    The need for the establishment of barrier devices in fall trunks in drainage systems in buildings has become more pronounced, with the intention of counteracting the entry of rats into residential properties. In addition, there are environmental problems associated with manure collection facilities in fur farms, which include manure collection manure which is fed into a manure collection system via vertically oriented pipes. The environmental problems cause misalignment and, in extreme cases, the death of fur animals that reside in cages located near said tubes. It is recognized by the invention that both of the above issues are solved by establishing a one-way valve (2) comprising an annular member (8) for insertion into a tube (4) comprising a downwardly sloping surface (10) which opens into a Rectangular aperture comprising a plurality of spring loaded flap portions (24) jointly blocking the aperture of the tube (4) allowing passage of fluids / liquids and particles to pass from above. In a particular embodiment of the one-way valve (2) according to the invention, the annular member (8) is formed with a sleeve (40) and a tip end (42), so that the one-way valve (2) can form part of a fall stem.

    The present invention relates to a one-way valve / block for vertically oriented drain pipes.
    The applications and the purpose of placing such one-way latches / vents are numerous. For example, such barriers are placed on falls for the purpose of preventing rats and other creeps from entering residential properties through the sewer system, in other cases barriers / vents are used to prevent flooding when the sewer systems do not have sufficient capacity during extreme rainfall events. however, there is a need for use of one-way barriers / valves for other purposes, for example in connection with slurry scraper systems and gyile plants with trenches and vertically oriented drainage pipes, for production units for fur animals. The slurry scrapers are of the type comprising a gutter below the cages for the fur animals, which culminates in one or more vertically oriented drainage pipes which are connected to a manure collection system produced by the fur animals in the cages.
    The automatic systems are made up of a draft wire that is passed across the channels, drawn by a game where a number of scraper units are attached to the draft wire that carry the slurry against the drain pipes. The scrapers are provided along the circumference of the scraper end with a one-row plastic brush for the purpose of "sweeping" the inside sides of the gutter for slurry.
    However, there may also be facilities including scraper ends where the manure is scraped to, and down into the drainage pipes from the manure end, with a manually operated scraper.
    Naturally, a certain number of vertically oriented drainage pipes, standing in connection with a manure collection tank, occur in a common fur animal production facility. Said vertically oriented drainage pipes are typically located near the ends, and in one of the outermost phases of the respective production halls, a fur animal production unit. For larger production units, it may be necessary to locate said vertically oriented drainage pipes immediately below a plurality of cages in the production unit. Ρΐηιη7πκηη
    Practical observations have shown that fur animals living in the cages around said vertically oriented drainage tubes take up less food, and grow slower than animals placed in cages further away from said tubes. This results in less skins, thereby losing revenue for the producer of skins. is very dependent on the size of the skin produced. Furthermore, a higher mortality rate of animals staying in the cages near said drains for the slurry plant has been observed, which is of course unacceptable, primarily from an animal ethical point of view, but also from an economic point of view.
    One of the explanations for the smaller uptake of animals staying in the cages around the drainage pipes is that the ammonia vapors (fumes) from the manure supplied to the drainage pipes rise and pollute the air in the area around them, which degrades the quality of the air that the animals that staying in the cages near and immediately above these pipes must breathe, causing a lack of well-being and a lack of hunger for the animals. In particularly unfortunate cases, the environmental impact of the pipes in the form of ammonia vapors, can cause stress on the animals, and in some cases have lethal effects.
    It would be preferable to thwart said rise of ammonia vapors from said manure drain pipe, which could be achieved by mounting a suction in the drainage system which ensures that the ammonia vapors (vapor) remain in the pipes, but this leaves another problem, namely, to which Extracted air must be emitted. With the stricter environmental regulations on emissions of nitrogen to the atmosphere, extraction of air will hardly be a solution that will satisfy the requirements of a WM assessment in connection with a fur farm.
    Thus, it will be necessary to seek other solutions, and here, actual valve valves have been tried to block the opening of the pipes when no slurry passes through them. However, practical experience has shown that there are major problems in the operation of such flap valves, as they are clogged with straw and manure, which is why they have not spread, and instead the above-mentioned scenarios regarding smaller skins and greater mortality must be accepted.
    It is an object of the invention to provide a device which prevents the entry of pests such as rats and mice, and which furthermore prevents the propagation of ammonia vapors (vapors) from vertically oriented drainage pipes that transport / carry smelling fluids such as manure and wastewater.
    It is recognized by the invention that such a device is constituted by a one-way valve for vertically oriented drainage pipes, characterized in that the valve comprises an annular workpiece whose outer diameter is approximately but smaller than the actual diameter of a current drainpipe which comprises a workpiece. downwardly and toward the center axis of the tube, inclined surface extending between the periphery of a first upward end of the annular member, and to a multi-angular aperture adjacent a second downward end of the annular member, which square opening, below each of the the sides thereof, and at a distance therefrom, comprises a flap portion mounted about a hinge connection, the first side of which is hinged to the annular body, and spring-loaded towards the upward end of the annular member for impact against a stop near the hinge connection, so that the flap portions in association block the opening in the tube but allow fluids Fluids and particles advanced to the tube may pass past the flap portions by deflecting the spring-actuated flap portions.
    This provides the advantage of a one-way valve that allows passage of fluids / liquids and particles to pass to the subsequent drainage system, but at the same time prevents the presence of the valve undesirable living creatures under the valve such as rats, which is prevented by the spring-actuated flap portions, which immediately after passage of supplied fluids / liquids and particles, block the opening in the annular blank.
    Furthermore, experiments have shown that the presence of the valve according to the invention, in slurry for livestock production units, of the kind comprising vertically oriented drainage pipes in connection with a manure collection system, and in particular automatic slurry scavenger plant production units, - causes a considerable reduction in the amount of ammonia vapor rising through the vertically oriented tube, the opening / lysis of a vertically oriented tube with the one-way valve after passage of fluids / liquids and particles, the valve flaps tilting back to the initial position and substantially blocks the opening in the tube, thus interrupting the connection between the pipeline system and the collection point of the fluid / liquid and particles supplied. In order to secure the valve according to the invention against unintentional clogging, with consequent lack of locking function, the tiltable, spring-actuated flap parts can be triangular. This embodiment causes the fluid / liquid particles to pass the valve not to be adhered to the flap portions resulting in clogging of the valve, as the area of the individual flaps decreases downward, which causes the probability of adhesion to the valve flap surfaces during passage of the fluid / fluid and / or the particles are very small. In a particularly preferred embodiment of the valve according to the invention, the pivotally mounted, spring-acting triangular flap members may be similar and configured as straight-legged triangles whose baseline comprises one half of the hinge joint which cooperates with the other half of the hinge joint attached to it. inner periphery of the annular workpiece, and whose like sides extend parallel to the tip ends, opposite to the baseline, which in the closed state of the valve is located in the center axis of the annular workpiece. In addition to the aforementioned advantages of the geometry of the flap parts, the advantage is further obtained that, since the triangular flap parts are similar, replacing a flap part in a current valve requires only one type of spare part, which is advantageous from a service and economic point of view. In order to be able to insert the valve according to the invention into an existing installation, the outside of the annular blank may comprise retaining means for holding the valve in a preferred position in the light of a vertically oriented tube. In a preferred embodiment of the valve according to the invention, the retaining means are comprised of at least three ribbon members for mounting along the periphery of the annular member, which ribbon member comprises a first downward end for insertion into slots in the annular member, which ribbon member is formed with locking means cooperating with openings and locking means on the periphery of the annular workpiece, and another free end, which is bent as an inverted U-shaped hook, for attachment to a free end of the vertically oriented pipe.
    The advantage of this is that in this embodiment, the valve can only be immersed in a vertically oriented tube, and held in the luminaire by a vertically oriented tube, Ρΐηιη7ηκηη, hanging in the ribbon blanks whose folded Il-shaped hooks engage the free end of a currently vertically oriented pipe. In one embodiment of the valve where it is established in a new pipe system, the first end of the annular workpiece may comprise a socket with a sealing ring for tightly sealing the tip end of a drain pipe, and the outer periphery of the other end of the annular workpiece may be formed. as the tip end of a pipe, intended for tightly fitting up into a socket with a sealing ring in a drain pipe.
    Hereby it is achieved that the valve according to the invention can be built into a drainage system with vertically oriented drop trunks, where the valve can act as a rat stop.
    The invention will be explained in more detail below with reference to the drawing, wherein

D * i nine ητηιτηη In connection with the description of the present invention, it has been decided to use the one-way valve 2 according to the invention in vertically oriented pipes in connection with slurry scraper systems and slurry systems with gutters 6 and vertically oriented drainage pipes 4, for production units for fur animals . The slurry scrapers are of the type comprising a gutter beneath the cages for the fur animals, which culminates in one or more vertically oriented drain pipes 4, which are connected to a manure collection system (not shown) for manure produced by the fur animals in the cages. In FIG. 1, there is shown a first embodiment of the one-way valve 2 according to the invention, where it is intended for insertion into a vertically oriented drain pipe 4 in connection with a gutter 6 for collecting slurry from cages used for production and storage of fur animals.
    As can be seen, the valve comprises an annular blank 8, the outside diameter of which is approximately, but smaller, corresponding to the inside diameter of a current drain pipe 4, which blank 8 comprises a downwardly inclined surface 10 towards the center axis of the pipe extending between the periphery 12 of the upwardly facing first end 14 of the annular workpiece 8, and to a multi-angled opening 16 closest to the downwardly facing other end 18 of the annular workpiece 8. The multi-edged opening 16 comprises, under each of the sides 20 thereof, and at a small distance from them. , a flap portion 24 hingedly about a hinge connection 22, the first side of which 26 (cf. Fig. 4) is hinged to the annular body 8, and spring influenced by springs 25 towards the upward end 14 of the annular blank 8 for impact. against a stop 28 (cf. Fig. 5) near the hinge connection 22, so that the flap portions 24 jointly block the opening 30 of the tube 4 but allow fluids / liquids and particles which advanced to the tube 4, can pass past the flap portions 24 by deflecting the spring-actuated flap portions 24, by the weight of the fluids / liquids and particles supplied. The flap portions 24 are shown in this and the next and described embodiments of the one-way valve 2 according to the invention as triangular, but the inventor reserves the right to use other shapes and embodiments. In FIG. 1 it is seen how the one-way valve 2 is arranged by passing it through the nozzle end 32 of the slurry end and down into the vertically oriented tube 4. In the illustrated embodiment of the one-way valve 2, three upwardly oriented holding means 34 comprise three first free end 33 of the holding means. 34 comprises apertures 35 for receiving locking mechanisms 37 in scenes 39 with locking mechanisms 41 in annular blank 8, so that when locking the first free end 33 of the holding means in a relevant backdrop 39, the locking means 41 are displaced through the opening 35 and locking the holding means 34 in the backdrop 39. The second free end 36 is bent so that they can engage the end of the pipe 4 inserted in the spout piece 32, whereby the one-way valve 2 is held in place as shown. 2nd
    FIG. 3 shows the slurry end 6, with the vertically oriented tube 4, seen from below, and where the one-way valve 2 is open, the flap portions 24 being bent downwards, creating a star-shaped groove 27 in the vertically oriented tube 4, where fluids / liquids and particles can pass.
    The position shown by the flap portions 24 in the valve 2 is atypical and occurs only when fluids / liquids and particles pass through the one-way valve 2 according to the invention. Normally, when no fluids / liquids and particles are supplied through the one-way valve 2, the flap portions 24 will be located so that the opening 16 through the one-way valve 2 is blocked, which occurs by the action of the springs 25. This means that there is no free opening between the underlying pipe system. and manure collection systems when the spout and thus the one-way valve 2 according to the invention are not supplied with fluids / liquids and particles, which causes a considerable reduction in the odor and fumes from the underlying pipe system and manure collection system. This results in significantly better environmental conditions for the fur animals located in cages near and immediately above the spawning socket 32 and the manure drainage 4, resulting in greater quality of life and willingness to feed, and ultimately larger skins. In FIG. 4 is a sectional view taken along line E-E of FIG. 3, the one-way valve 2 is again shown in the open position, with the flap portions 24 in the bent position. In FIG. 5, there is a detail sectional view of a flap portion 24 of the embodiment shown in FIG. 1-4, one-way valve 2, according to the invention, shows how the hinge connection 22 is positioned such that the flap portions 24 are located at a small distance a, from the bottom edge 19 of the sides 20 of the multilayer opening 16, below the inclined surface 10 of the annular workpiece 8, at a portion 38 projecting on the bottom edge which constitutes the stop against which the spring-actuated flap portions 24 in the closed position of the valve are pressed against. This construction causes the one-way valve 2 according to the invention not to be clogged by particles supplied to a current vertically oriented tube in which the one-way valve 2 is arranged. In FIG. 6 is a top view of another embodiment of the one-way valve 2, according to the invention, which comprises a sleeve 40 and a tip end 42 for incorporation in a vertically oriented pipe system, cf. FIG. 7, 8 and 9. This is done by changing the shape of the annular blank 8 so that it will in effect constitute a piece of pipe, comprising the aforementioned sleeve 40, formed with a recess 43 for receiving a sealing ring (not shown). , for tightly fitting the tip end 44 of a tube 46 located above the one-way valve 2 and a tip end 42 intended for accommodating the sleeve 48 on a tube 50 located below the one-way valve 2. FIG. 8 and FIG. 9th
    As shown in FIG. 6, the hinge joints 22 are protected by the sloping surface 10 so that particles do not have the ability to attach to the hinge joints, thereby preventing the spring-actuated flap portions 24 from tilting back to the starting point and blocking the liner 27, where the flap portions 24 are located. abutment with the protruding portions 38 constituting the stop of the spring-actuated flap portions 24 in the closed position of the valve being pressed against by the springs 25, cf. 5 and FIG. 7. In FIG. 7, the one shown in FIG. 6 shows the second embodiment of the one-way valve 2, according to the invention, shown in perspective view, seen obliquely from above, where the inclined surface 10 is rendered invisible, so that the hinge connections 22 between the annular workpiece 8 and the flap parts 24 and the springs 25 are visible. The one-way valve 2 operates in the same manner as described above, with the difference that it now appears as a fully integral part of a vertically oriented pipe system. FIG. 8 shows how the valve shown in FIG. 6 and FIG. 7, the tip end 44 of a tube 46 located above is inserted into the sleeve 40 of the one-way valve 2, and in FIG. 9 shows how the tip end 42 of the one-way valve 2 is inserted into the sleeve 48 on an underlying pipe 50. In some cases, it may be convenient to place a cleaning element (not shown) immediately below the one-way valve 2, should a need arise for replacement of wear parts. the one-way valve 2 according to the invention.
    In this construction of the one-way valve 2, it will not be possible, for example for a rat, to pass the one-way valve 2 from below, simply because the flap parts 24 in combination will block the opening 16 in the pipe. D4 ΓΜ Λ-7Γ ί ^ ηΓΐ
    According to the invention there is provided a one-way valve 2 which satisfies both a need for blocking the illumination in vertically oriented pipe systems, for example drop trunks, so that animals such as rats cannot pass further into the pipe system in, for example, the drainage system in a house, and a need to prevent unwanted ascent of vapors and unpleasant odors from manure collection systems, in particular manure collected in pits at fur production facilities.
