    Reagent mixing device and inflatable duct plug containing said device. Object of the invention.
    The object of the invention is a reagent mixing device, applicable to shutters inflate bias ducts; as well as an inflatable duct shutter containing said reagent mixing device. Field of application of the invention.
    This invention is applicable in the sealing of passageways of electrical, telephone or similar cables, for the protection of said cables. State of the art
    Currently there are different sealing devices on the market intended to seal those ducts inside which pass cables such as electrical, telephone or similar cables.
    These devices comprise an inflatable outer bag that has inside it means for generating and / or releasing a gas capable of inflating said outer bag, so that said bag adapts to the free space inside the duct making its sealing .
    Specifically, in document ES 2 302 866T3 (EP 1 614 953) a device of this type for sealing conduits used in electrical, telephone and similar lines is described, the device being composed of a flexible rectangular sheet with folding lines and provided with a perimeter strip that facilitates its adhesion or welding forming a closed compartment, as a bag, whose walls once arranged around a main conduit at the end of a pipe or conduit to adapt to the curvature of said conduit or conduit and said main conduit when the compartment is inflated.

    This device comprises for the inflation of the compartment a small tank loaded with a pressurized gas, fixed to an internal wall of the compartment and provided with opening means that can be manipulated from the outside of the compartment to open a hole or outlet port of the tank to allow gas to escape from the tank into the compartment and cause gradual and slow inflation of the compartment.
    Other devices are also known for sealing ducts that house a reaction system inside the inflatable bag to generate the gases necessary for inflation of said bag.
    Specifically, in document ES 2 546 453 T3 a pressure generating device for sealing ducts is described in which the inflatable outer bag contains an inner bag carrying a reaction system capable of releasing gases capable of inflating the outer bag; said reaction system comprising a solid reagent and a liquid reagent contained in a collapsible bag.
    The characteristic of said device is that the folding bag is provided on one of its sides with a weaker weld that breaks when subjected to manual pressure, the reagents are mixed, and the inner bag has a partial weld that circumscribes an area where the reaction of the solid reagent and the liquid reagent takes place.
    Document ES 2 562 712 A 1 also describes a duct sealing tank, and a sealing device containing said reservoir.
    The tank in question comprises an elongated hollow body of flexible material with a first section and a second section containing a liquid; said hollow body when pressed releases the liquid contained therein.
    5 l O The sealing device has an external, tightly sealed, flexible container, inside which the aforementioned tank is housed and a flexible container in turn contains a carbonated chemical compound and a reagent, so that when the tank is pressed, the release of the liquid contained therein; said liquid, upon contact with the reagent of the flexible container, causes an effervescence reaction that produces a gas, and thereby inflation of the flexible container.
    15 20 A generalized disadvantage of the aforementioned background, provided with a reaction system to generate an inflating gas from the bag, is that the liquid reagent container reservoir is housed inside said outer bag and must be manually pressed to cause the exit of the liquid and its mixed with the reagent; it is usual that the discharge of the liquid is carried out incompletely since part of it returns to the inside of the tank when the tank is manually depressed, and the reagent of the liquid reagent into the tank is favored by the gas pressure itself generated during the initial mixing of the reagent and the liquid.
    25 The applicant of the present invention is unaware of the existence in the market of reagent mixing devices applicable to inflatable duct shutters that have an automatic release, injection and mixing system, capable of guaranteeing the release of all the fluid contained in the tank and intended to be mixed with the reagent to generate inflation gases of the inflatable duct shutter.
    30 Description of the invention
    To solve the aforementioned problems, a reagent mixing device has been devised, applicable to inflatable duct seals; as well as a shutter
    inflatable duct containing said reagent mixing device.
    The reagent release and mixing device, object of this invention, comprises a reagent product container connected to a liquid dispenser containing a fluid intended to be mixed with the reagent product causing a release of inflation gases.
    According to the invention, the fluid dispenser comprises:
    a cylindrical reservoir container of the fluid and having at a front end a mouth of smaller diameter coupled to a conduit of connection with the reagent product container;
    a plunger housed in the reservoir with the possibility of displacement between a rear loading position and a previous fluid discharge position;
    a thrust spring that acts on the plunger and tends to move it towards
    the previous position of discharge of the fluid, a trigger that can be operated manually, which retains the piston in the rear position of loading and which, when released, automatically causes the sudden displacement of the piston to the previous position of discharge by the action of the thrust spring and the discharge of all the fluid contained in the reservoir into the container carrying the reagent product.
    With the aforementioned characteristics, it is guaranteed that once the trigger is activated, all the fluid contained in the reservoir is moved to the reagent product container, coming into contact with the same and guaranteed an adequate reaction of the reactive product, and the generation of gases
    Both the reactive product and the fluid in charge cause a reaction with gas release, are of a known type, for example a carbonated chemical compound and water, which when coming into contact cause a reaction that releases CO2.
    The inflatable duct shutter object of this invention, comprising a flexible, inflatable, bag-like body, has the particularity of incorporating the aforementioned release and reagent mixing device for inflation.
    According to the invention, the reagent container is housed within the flexible body of the inflatable shutter, it being provided that the fluid dispenser connected by a flexible conduit to said reagent connector can be arranged either inside, or in the exterior, of said inflatable flexible body. Description of the figures.

    The fluid dispenser (3) comprises a cylindrical reservoir (31), fluid container (F), which has at a front end a mouth (32) of smaller diameter coupled to the conduit (2) connecting with the container (1) of reactive product (R).
    Inside the reservoir (31) a piston (33) is housed with the possibility of displacement between a rear loading position shown in Figures 1 and 2, and a previous fluid discharge position shown in Figure 3.
    The dispenser (3) comprises a pushing spring (34) that acts on the plunger and tends to move it towards the previous fluid discharge position shown in Figure 3; , a manually operated trigger (35), represented in this case by a tilting trigger, which retains the piston (33) in the rear loading position shown in Figures 1 and 2, and which, when actuated, releases the piston (33) automatically causing the thrust spring (34) the sudden displacement of the piston (33) towards the previous discharge position, and the discharge of all the fluid (F) contained in the reservoir (31) in the container (1) carrying the reactive product (R).
    The mixture of the fluid (F) and the reactive product (R) causes a chemical reaction with the release of gas.
