Description

The proposed technical solution relates to fire fighting equipment and can be used in fire extinguishing installations to obtain a spray torch of a fire extinguishing liquid and for its uniform distribution over the area protected from the fire.

The most common designs of sprinkler sprinklers consist of a housing with a fitting, a shut-off device with a thermal lock, a spray outlet, and the shut-off device consists of a cover and a compensator.

When triggered by a heat source, the thermal lock is destroyed, the flow of extinguishing fluid, passing through the outlet of the fitting, moves the lid and compensator of the locking device to the area of connection of the handle with the sprinkler outlet, where they can wedge and freeze under the action of the fluid flow, breaking and distorting the concentric shape spray pattern, thereby deteriorating the irrigation uniformity of the area protected from the fire.

In order to improve the uniformity of irrigation of the protected area, it is necessary to ensure that the parts and parts of the locking device and thermal lock from the flow of extinguishing agent spent, which have become unnecessary.

In the well-known sprinkler sprinkler RU 18931, a spring is used to remove unnecessary parts of the sprinkler from the fluid stream after actuation, which is fixed in the initial state by the arms of the housing and bends around the lid of the locking device.

When the thermal lock is activated, the spring, being released, pushes the cover and the compensator to the side of the arches, thereby preventing these parts from hanging at the junction of the arch and the socket.

A relatively new sprinkler RU 152784 is known, which has a fairing with a through hole at the point of convergence of the arms, a socket is fixed on the fairing, and a glass bulb and a spring membrane are installed between the fairing and the nozzle, covering the nozzle opening and acting as a locking device for the sprinkler sprinkler.

The flattened shape of the spring membrane does not allow a reliable engagement of the membrane using a discharge spring in the same way as in the sprinkler according to RU 18931 and does not allow for the forced removal of the membrane with the help of such a spring after the thermal lock has been triggered away from the arches.

As a prototype taken sprinkler according to patent RU 152784.

The disadvantage of the sprinkler is the possibility of freezing (jamming) after the sprinkler of the spring membrane is activated in the area of convergence of the arches with the cowling, which causes irregularity in the irrigation of the protected area, which reduces the extinguishing efficiency.

The task to which the utility model is directed is to increase the extinguishing efficiency.

This problem is solved due to the fact that a sprinkler sprinkler containing a nozzle with converging arches forming a fairing at the convergence point in which a through hole is made with a deformable element located, a socket is fixed, a glass bulb and a spring membrane are installed between the fairing and the fitting, which closes the outlet of the sprinkler, according to the utility model, at an equal distance from the arches, in one place, on the interface line of the spring membrane with the seat in the sprinkler housing but connecting the elastomeric element.

The elastomeric linking unit may be made of an aqueous dispersion of rubber or, for example, of the adhesive material “Latex Elaftor 7000” TU 2294-019-13693708-2004, by metered application in the form of a droplet at the place where the membrane is joined with the body, followed by polymerization of the applied material in natural conditions.

The presence of an elastomeric link between the membrane and the body of the sprinkler, away from the arches, allows the membrane to be moved away from the plane in which the arches are located after the irrigator is triggered, thus, any effect on the extinguishing medium flowing from the outlet is eliminated, while maintaining the specified uniform irrigation.

The technical result provided by the above set of features is the increased extinguishing efficiency due to the stable predetermined uniform irrigation of the protected area.

The operation of the utility model is explained in more detail using the drawings shown in FIG. 1, 2, 3, 4.

FIG. 1 is a cross-sectional view of a sprinkler sprinkler in a running condition;

FIG. 2 is a sectional view of a sprinkler sprinkler on the right in a curb condition;

FIG. 3 - bottom view of the sprinkler sprinkler in running order;

FIG. 4 - view of the sprinkler sprinkler on the right in the worked state.

The sprinkler sprinkler consists of a nozzle 1 with an outlet 2 closed in a running state with a spring membrane 3 fixed in the seat socket 4, two arcs 5 extend from the nozzle, which converge on the fairing 6, in which the hole 7 is made and the socket 8 is fixed on the outside , a thermal bulb 9 is installed between the spring membrane and the deformable element 10 fixed in the fairing, while at the same distance from the arches, in one place, on the interface line between the spring membrane and the seat socket, a connecting el tamernoe link 11.

The sprinkler works as follows.

When exposed to the heat flow of air, the thermobox 9 breaks down, the spring membrane 3 leaves the seat 4 under the influence of the pressure of the extinguishing agent flow, but, under the action of the compressive forces of the elastomeric connecting link 11, deviates to the side from the plane in which the arms 5 are located, without interfering with the free passage of the flow extinguishing agent.

Thus, due to the presence of an elastomeric connecting link, the task is solved to increase the extinguishing efficiency (a given uniformity of irrigation of the protected area is ensured).
