Abstract

A sprinkler sprinkler is used for automatic extinguishing, it contains a nozzle with converging arches, a cowl in which a through hole is made with a deformable element installed in it, a socket is fixed on the cowl, a glass bulb and a spring membrane are installed between the deformable element and the nozzle, which covers the outlet of the sprinkler on the membrane has a spring bar in tension, clinging hook-shaped ends to the arms.

Description

Sprinkler sprinkler refers to fire fighting equipment and is used for automatic operation, to obtain a spray torch of a fire extinguishing agent (water or water solution) and for uniform distribution over the area protected from fire.

Known sprinkler sprinkler according to patent RU 163094, taken as a prototype.

The known sprinkler contains a nozzle with converging arches, forming a fairing at the convergence point, in which a through hole is made with a deformable element located in it, a socket is fixed, a glass bulb and a spring membrane are installed between the fairing and the nozzle, which covers the outlet, at the same distance from the arches, in one place, on the interface line between the spring membrane and the landing socket in the sprinkler body, a connecting elastomeric link is made.

During the actuation of the sprinkler, due to the tightening forces of the elastomeric connecting link, the membrane and the remnants of the triggered thermal bulb are moved away from the plane in which the arches are located, the flow of extinguishing agent is freely passing, the membrane and the fragments of the triggered glass thermoball are freely removed from the sprinkler, creating the necessary conditions for irrigation of the protected area.

A disadvantage of the known sprinkler is the susceptibility to rapid aging of the elastomeric unit under the influence of unfavorable external factors (the ultraviolet component of light exposure, temperature changes), which leads to the loss of the given function by the unit.

The task to which the utility model is directed is to increase the life of the irrigator.

The problem is solved due to the fact that the sprinkler sprinkler is made, comprising a nozzle with converging arches, forming a fairing at the convergence point, in which a through hole with a deformable element located in it is made, a socket is fixed, a glass bulb and a spring membrane are installed between the deformable element and the nozzle. , which closes the outlet of the sprinkler, according to a utility model, a folding spring bar is made in tension with hook-shaped ends, which atseplena for the wishbone, the bracket is mounted on the membrane on one side of the plane of the handles.

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

FIG. 1 - a general view of the irrigator on the right in a section in the equipped form;

FIG. 2 - view AA of the irrigator in running order.

The sprinkler sprinkler consists of a nozzle 1 with an outlet 2, which is closed in the running state by a spring membrane 3, which is fixed in the landing socket 4; two arches 5 depart from the fitting, which converge on the fairing 6, in which the hole 7 is made and a socket 8 is installed on the outside; a thermal bulb 9 is located between the spring membrane and the deformable element 10 fixed in the fairing; the hinged spring plate 11, in tension, is mounted on the membrane and hook-shaped ends 12 are hooked on the arms.

The sprinkler works as follows.

When exposed to the heat flow of air, the thermobox 9 is destroyed, the spring membrane 3 exits the seat nest 4 under the pressure of the extinguishing agent, but when it experiences the resistance of the bar 11, it turns around and, under the action of the extinguishing medium, goes away from the plane in which the arms 5 are located, entraining the remnants of the thermal bulb are behind them, without interfering with the free passage of the stream.

The hinged strip leads the spring membrane away from the sprinkler, preventing it from hanging in the sprinkler, and thus provides the necessary conditions for free irrigation of the protected area; the service life of the proposed mechanism for withdrawal from the sprinkler sprinkler of the spring membrane and the remains of the destructible thermal bulb is significantly increased, less dependent on adverse operating conditions.

Claims (1)

A sprinkler sprinkler containing a nozzle with converging arches forming a fairing at the convergence point, in which a through hole with a deformable element located therein, is provided with a socket, a glass bulb and a spring membrane are installed between the deformable element and the nozzle, which covers the outlet of the sprinkler, characterized in that that the folding spring bar is made in tension with hook-shaped ends, which is hooked on the arms, while the bar is installed on the membrane one side of the plane of the arrangement of the arms.
