The invention relates to fire fighting equipment, in particular to devices for removal of smoke from the premises on the floors of the building through openings in seriousa on the axle by means of limb and through the anchor holes on the walls of the circuit holder actuator, the load associated with the help of a hook holder and by means of the lever with the valve stop and the gasket (and.with. The USSR 1016625, CL F 24 F 13/08, 1981 - prototype).

In this device, the lever locking element is fixed on the circuit, and the emphasis placed on the inclined flap. A short lever arm is in contact with the stops, and a long arm with a weight at the end connected with the holder of the actuator. This kinematic relationship leads to a weakening of the contact of the short arm with an emphasis moment created by the weight of the cargo. When this valve, shifting under its own weight down, moving away from the path. Resulting in the upper horizontal section there is no contact of the valve circuit, which reduces the resistance demoralizing.

In addition, the flap is supported by limb on the axis and through the anchor holes on the walls of the path, not tight and the lower horizontal section, as round holes do not allow the flap to adhere to the path.

When triggered, the locking element flap in case of sticking on the path may not open as the cargo interacting with emphasis through the lever when the drop hangs above the doorway on the path of the friction force when coab and it may not be enough to open the valve, that reduces the reliability of the device.

In addition, the leash to limit pivoting the flap is mounted on the circuit that can cause warping as a damper, and the path to a dynamic load.

The objective of the invention is to improve the reliability of operation and create significant resistance to demoralizing.

For this purpose, the smoke removal device containing the circuit, rotary damper, based on the axis using the limb and through the anchor holes on the wall contour, the holder with the drive, the load associated with the help of a hook holder and by means of the lever with the valve stop and the seal has an additional chute attached to the flap on the perimeter and on the front wall of the slot, when the gasket is placed in the trench with the possibility of contact with the attachment plane when immersed loop through the slot into the gutter, the anchor holes on the walls of the circuit have an elongated shape and are inclined, the emphasis has the form of a movable pin with a spring end and is mounted above the opening in the circuit, a lever connected with the flap hinge, and the weight attached to the lever with the possibility to adjust its position relatively to oporinia illustrated by drawings, where in Fig.1 shows a device, smoke, General view; Fig.2 - node I in Fig.1.

The smoke removal device contains a circuit 1, the rotary valve 2, resting on the axle 3 by means of the limb 4 and through the support hole 5 - wall 6 of the circuit, the holder 7 with the actuator 8 (electromagnet). It also contains the load 9 connected by means of a hook 10 with the holder and by means of the lever 11 with the valve, the stop 12 and the sealing gasket 13.

The device additionally has a groove 14, secured to the flap on the perimeter and on the front wall of the slot 15. When the gasket is placed in the trench with the possibility of contact with privalochnoj plane when immersed loop through the slot into the gutter.

Anchor holes 5 on the walls of the circuit have an elongated shape and are inclined.

The stop 12 has the form of a movable pin has a spring end with a vertical downward gradient above the doorway on the path.

The lever 11 is connected with the flap hinged by a pin 16.

The load 9 is fixed to the lever 11 by means of threads 17 with the possibility to adjust its position relative to the stop 12 and the interaction with the holder 7 through the hook 10 and focus 12 is not the s in the gutter protects it from damage, keeps you from falling out outside the trench reduces the possibility of warping of the valve and accordingly the strip.

The smoke removal device works as follows.

The valve 2 in the closed position is fixed on the circuit 1 by the holder 7 connected with the armature of the electromagnet 8. Cargo 9 hook 10 rests on the holder and in contact directly with a spring stop 12. The position of the cargo on the lever 11 by means of threads 17 is adjusted relative to the stop so that the flap adjacent to the path at the top. Seating the valve to the path around the perimeter of the support hole 5 on the walls 6 of the circuit is made oblong and are tilted, due to this axis 3 and the flap under its own weight shifted down and to the path.

When turning on the drive anchor of the solenoid disengages from the holder. Load your weight through the hook 10 rotates the holder down and at the same time rotates around the axis 16 with the lever 11. To eliminate the hang of the cargo at the stop bearing surface of the latter is performed with a vertical slope. At the end of his falling cargo flies on the valve and held in it, and the flap having an impulse, under the action of its own weight and doba 16 angle, which eliminates the possibility of distortion of the valve and circuit.

In the initial position valve with return cargo manually. Upon contact of a hook with a bevel holder actuator deviates from the doorway. When the cargo with his hook occupies a position between the holder and the stop, the actuator is in its place and thereby fixed closed flap.

In order for the valve to open manually, rather actuator to rotate on itself about the axis 19.

Feasibility the ability of the claimed invention in comparison with the prototype is to provide improved operational characteristics of the device by increasing reliability and create significant resistance to demoralizing.

The smoke removal device containing the circuit, rotary damper, based on the axis using the limb and through the anchor holes on the wall contour, the holder with the drive, the load associated with the help of a hook with the holder and with the lever - valve, stop and strip, characterized in that it additionally has a spout attached to the flap on the perimeter and on the front wall of the slot, when the gasket is placed in the trench with contactcenter have an elongated shape and are inclined, the emphasis has the form of a movable pin with a spring end and is mounted above the opening in the circuit, a lever connected with the flap hinge, and the weight attached to the lever with the possibility to adjust its position relative to the stop and interact with the holder through a hook and focusing directly.
