    The present invention relates to a device (1) at the valve (2) for air control of a building through a single opening in a wall by means of a temperature-sensitive sensor body (6) and a valve plate (7) regulating the opening (4). The invention solves, among other things, the problem of draft and odor in strong winds. With a non-return valve (8) in the supply air valve, the ventilation remains largely intact without any discomfort in the form of increased draft or odor spread. (Fig. 1)

    The present invention relates to a device for a valve for air control of a building through an opening in a wall by means of a temperature-sensitive sensor body and an opening regulating valve plate.
    It is previously known with self-regulating and self-closing valves of the type specified above for ventilation purposes in buildings, e.g. as shown in SE451 502B and SE461 747B. However, these do not solve problems that can arise due to over-ventilation in strong winds and the resulting negative pressure in the building, since then adjacent valves are often completely closed manually. A common scenario regarding ventilation in strong winds is as follows: When it blows hard against the building, the supply air inside the building increases and is experienced as drafts from the valve. On the read side, the function is reversed and the supply air valve becomes the exhaust air valve instead.
    Since this is then experienced as a draft from the supply air valve on the windward side, this means that this valve is usually closed manually. This creates a negative pressure in the building with a great risk of so-called backlash and odor and air spread through flooding between the apartments in an apartment building.
    There are then two problems to be solved, namely partly to solve the problem of drafts and retractors and partly also to achieve automatic regulation of the ventilation opening and thereby reduce the need for manual regulation and the risk that the valve remains in the closed position at undesired times, but with the possibility of adjusting the degree of closure.
    The main object of the present invention is, among other things, to solve said problems in a simple and efficient manner. The said object is achieved with a device according to the present invention which is mainly characterized in that a combined air deflector and non-return valve is arranged at the opening inside the valve plate.
    This is done to increase comfort, reduce energy consumption and reduce the risk of moisture and mold damage. This is achieved by means of a combined air deflector and non-return valve and which reduces the risk of over-ventilation in strong winds and which spreads the air in a way that minimizes the feeling of draft. Automatic adjustment of the ventilation opening after changing the outdoor temperature and with a non-return valve that prevents over-ventilation in strong winds provides improved heat economy that lowers energy consumption.
    Automatic control of the ventilation opening but with the possibility of manual control reduces the need for manual control and thus the risk of the valve being forgotten in the closed position with an increased risk of moisture and mold damage.
    The invention is described below as a preferred embodiment with reference to the accompanying drawings, in which Fig. 1 shows in perspective and partly in cut position a device at a valve and with a non-return valve shown in open position and with the combined air deflector and non-return valve in effective air diverting position, Fig. 1A shows the device with the valve in open position and the air deflector and non-return valve in activated closed pull-back position, Fig. 2 shows a cross-sectional view of the device with valve and air deflector and with non-return valve in open activated position, 10 l 25 Fig. 3 shows the device with the valve in the closed screwed-in position and with the air deflector and the non-return valve in the closed pull-back position, and Fig. 4 shows in detail the bearing for the valve plate and with the end stop for screwing in the valve plate.
    A device 1 at a valve 2 which is intended for air control of a building 3 through an opening 4 in a wall 5 by means of a temperature-sensitive sensor body 6 and with a said opening 4 regulating valve plate 7 comprises according to the present invention a combined air deflector and non-return valve 8 and which is arranged at the opening 4 and inside the valve plate 7. That is to say between the valve plate 7 itself and a frame 9 for said valve 2.
    The said combined air deflector and the non-return valve are formed by an opening closable disc 8 which is arranged movable. The disc 8 is received supportively with part 10 of its circumferential portion tiltable around the lower portion 4A and 4 of the frame 9, respectively. 9A in holder ll.
    More specifically, a number of holders 11 are preferably located on the lower part 9A of the frame 9, preferably at a mutual distance A from each other. It is convenient to arrange at least two such holders, as shown in Fig. 1 and Fig. 1A, so that said combined air deflector and non-return valve disc 8 can be received by said holder 11, preferably that the circumferential portion of the disc supports against projecting support portions 12 and that the lower side portion of the disc is retained laterally by means of upwardly projecting stop portions 13. It is also possible to design other holders ll than the hook-shaped ones shown and also with a different number, from a single up to many. The combined air deflector and non-return valve disc 8 is received inclined towards the inside 7A of said open valve plate 7 in the normal opening position I of the valve 2, see Figs. 1 and 2, and thereby directing incoming air 14 upwards in the direction towards the room in question 16 ceilings 17, but to close said opening 4 in the event of a pull-back. In this case, at said non-return valve-forming position II, see Figs.
    Suitably, said combined air deflector and non-return valve disc 8 is formed of a porous fiber and / or textile material and which is provided with a center hole 40. The disc 8 is threaded with the center hole 40 enclosing the sensor body 18 and holder and the valve plate 7. 19. which is stored adjustably by means of threaded connection 20, 21 between the valve plate 7 and a sensor housing 22 receiving the sensing body 6, is arranged to cooperate with a number of stops 23, which limit the automatic closing movement of said valve plate 7 and thereby limit the air gap 24 formed between the valve plate 7 and its frame 9, for example to 4 mm, but that means 25 are provided which allow manual continued closing movement of the valve plate 7 to the fully closed position, see Fig. 3.
    Suitably the said means 25 is formed by a resilient locking tongue 26 and a receptacle 27 thereof which is receptive to the housing 18 or the valve plate 7 hub 19 and said end stop stop 23 for the valve plate 7 hub 19 and with the end portion 29 of the valve plate center hub 19 for cooperation. Said abutment 23 is formed by lugs located on centered support arms 31 of the valve frame 9 which can be screwed to the wall 5. hub 19.
    A rotatable end cap 32 is arranged in a known manner to be locked to the housing 18 by means of internal locking means (not shown) and thereby form end stops for a compression spring 33 receivable therein with one end 33A thereof and the opposite end 33B of the spring abutting against the said support arms 31 of the frame 9 at its center.
    The nature and function of the valve and its device should have been apparent from the above and with the aid of the accompanying drawings.
    The invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, in particular as regards the nature of the various parts, or by the use of equivalent technology, without departing from the scope of the invention as defined in the scope of the invention.
