The invention relates to fire fighting equipment, namely, devices control the flow of operating ognegasitelem environment for fire fighting.

Known trigger-locking device (UPP), containing a pneumatic cylinder with a piston connected to the backbone with supplied ognegasitelem environment, building pad, magnetic drive, which made the pre-chamber connected with the cylinder through the bypass channel and constantly communicated with the motive gas cylinder through the inlet port (see the description of the utility model RU # 17676, published 20.04.2001).

The disadvantages of the known technical solutions are insufficient effectiveness of fire fighting systems because of the need to maintain the motive cylinder of gas under high pressure, and low reliability of the locking trunk with ognegasitelem environment.

The technical result of the claimed invention is to improve the efficiency and reliability of the device.

This object is achieved in that the shut-starting device, containing a pneumatic cylinder with a piston and a rod connected to the crane distribution device connected to the bus supplied ognegasitelem environment, building pad electromagnetic actuator, in which ruskovaara, associated with the cylinder through the bypass channel and constantly communicated with the motive gas cylinder through the inlet port, according to the invention, the bypass channel is equipped with mechanical spring-loaded shut-off body, a rod which is connected with the armature of an electromagnet opening of the bypass channel when moving the anchor and the bypass gas from the chamber in the pneumatic cylinder, and trigger the actuator is equipped with a manual transmission, made in the form of handles associated with thrust inside sleeve made therein longitudinal grooves in the thrust fixed transverse pin, the projecting ends of which are located in the slots of the sleeve with the possibility of relative movement of the sleeve and thrust in within the length of the grooves and the opposite end of the sleeve is bonded with the rod of the locking member.

The task is achieved by the fact that in the case of starting the electromagnetic actuator can be made unloading chamber in which is placed a spring locking member and which is communicated with starting the camera using a groove made in the stem of the locking member.

The task is achieved by the fact that the crane distribution device can be performed with the ball.

The task is achieved by the fact that the handle actuator can be equipped with protection is tion ring, the locking knob relative to the housing of the drive.

The invention is illustrated by drawings, in which:

1 shows a diagram of the device Assembly;

figure 2 - incision starting electromagnetic drive.

ROMs made according to the claimed invention, includes pneumatic cylinder 1 with a piston 2 and piston rod 3 connected, for example, with ball valve switchgear (not shown)connected to the backbone (not shown) supplied with ognegasitelem environment. Case 4 starting the electromagnetic actuator 5. In the housing 4 made the pre-chamber 6 connected with the cylinder 1 through the bypass channel 7, for example, through nipple 8. The camera 6 is constantly communicated with the motive gas cylinder (not shown) through the inlet port 9. The bypass channel 7 provided with a mechanical spring-loaded locking body 10, the piston rod 11 which is connected with the anchor 12 of the electromagnet 13, containing also the winding 14 and the core 15. The trigger actuator 5 is also equipped with manual transmission, made in the form of a handle 16 that is associated with a thrust of 17. Rod 17 is placed inside the sleeve 18 made therein longitudinal slots 19. In the deadlift 17 fixed transverse pin 20, the protruding ends of which are located in the grooves 19 of the sleeve 18. The opposite end of the sleeve 18 is bonded with the rod 11 of the locking body 10, for example, at the same time additional transverse pin 21. The handle 16 may be provided with protective ring 22, the locking handle 16 relative to the housing 4 of the drive.

In case 4 the starting of the drive can be made unloading chamber 23 in which is placed the spring 24 of the locking body 10. While unloading chamber 23 is in communication with the starting chamber 6 by means of a groove (not shown)made in the stem 11 of the locking body 10.

The device operates as follows. The pre-chamber 6 is constantly under the pressure of the gas coming out of the motive of the container via the inlet channel 9. The locking body 10 is drawn in by his side hole of the overflow channel 7 by means of a spring 24 and closes the gas outlet from the chamber 6. To enhance the pressure locking body 10 and parry pressure acting on the part of the area of its end surface, the gas is sent to the discharge chamber 23 of the groove made in the rod 11. The penetration of gas in other parts of the device is prevented by the installation of gaskets.

When receiving emergency electrical signal from the sensor fire on the electromagnet 13 of its anchor 12 is moved to the core 15 and pulls the rod 11, tearing off at this stop valve 10 from overlapping them holes bypass channel 7. Gas from the launching chamber 6 flows through the bypass channel 7 in pneumatic cylinder 1 and moves it then is the tier 2 and rod 3, which, in turn, opens the valve of the switchgear line feed agregating tools.

If necessary, you can open the locking body 10 and manually. To do this, move the rod 17 of the handle 16, pulling out his preliminary safety ring 22. The transverse pin 20 moves with the thrust 17 along the grooves 19 of the sleeve 18 to lock in the walls of the slots 19, and then begins to move and the sleeve 18, pulling the rod 11 of the locking body 10 together with the anchor 12. The presence of grooves 19 in the sleeve 18 allows you to move the rod 11 with the sleeve 18 relative to the stationary thrust 17 by operation of the electrical drive.

Thus, the effect of amplification through the use of pneumatic cylinder allows you to use a gas with a lower pressure in the motive cylinder, which significantly increases the reliability of long-term operation of the system due to the significant reduction of gas leaks. In addition, the effect of amplification also allows you to use the ball valve with sufficient force rotation due to the increased density of its installation in the pipeline and, consequently, more reliable locking.
