The invention relates to PMI in the wall of the exhaust shafts.You know the smoke removal device containing the circuit mounted on the opening of the exhaust shafts, a valve mounted for movement along the opening on the vertical guides placed in the box drive electromagnet holder, which is connected through a hook with flap and having a bevel on the front end, the hinge manual opening of the valve and seal (Patent RU 2159394, CL F 24 F 13/08, 08 In 15/00, 1999. - prototype).In this device, the labyrinth seal though and has resisted demoralizing, but it does not provide backlash-free coupling of the sealing surfaces of the valve and circuit, the smoke through the gaps will get that lowers the operational characteristics of the device.Elastic sealing elements on the circuit and the sealing surface of the valve do not form a closed sealing zone, the possible penetration of the smoke remains.The objective of the invention is to provide improved operational characteristics of the device by creating gapless resistance demoralizing.For this purpose, the smoke removal device containing the circuit mounted on the opening of the exhaust shafts, a valve mounted for movement hydrated through a hook with flap and having a bevel on the front end the hinge manual opening of the valve and the gasket provided with a compression spring and an eccentric clamp, and the flap is made in the form of a box-shaped outer wall and a retractable inner wall limited progress, rasperry compression springs, while the inner wall has a limb along the top and bottom edges and attached to the limb axis, through which it is connected with the outer wall through the elongated through holes on its sides, eccentric clamp has eccentricity, the greater the progress retractable wall was installed using round holes on the horizontal ends of the box-shaped outer wall and connected with the inner wall of the through oval holes on its limb both wall mounted with the possibility to fit each of them to a suitable mating surface contour assasino.The invention is illustrated by drawings, where Fig.1 shows a device smoke, front view; Fig.2 - section a-a in Fig.1; Fig. 3 - section b-B in Fig.1; Fig.4 - section b-b of Fig.1, the inner wall of the valve shown in the pushed position, and Fig.5 is a variant of the device with a sealing belt.The smoke removal device contains a circuit 1, the vertical guides, posted in box 3, the drive electromagnet 4, the holder 5, which is connected through a hook 6 with the flap and having a bevel 7 on the front end, the hinge 8 manual opening of the valve and the seal formed by the walls of the valve and circuit.The device is provided with a spring 9 compression ratio and Cam clamp 10.The flap is made in the form of a box-shaped outer wall 11 and sliding the inner wall 12 a limited stroke. Both walls rasperry springs 9.The inner wall has a limb 13 along the top and bottom edges and attached to the limb axis 14, whereby it is connected with the outer wall through an elongated through hole 15 made on the lateral sides of the walls 11. Holes 15 also serve as restrictors wall 12 forward.Eccentric clamp is made in the form of a round rod and attached to it a round rod of smaller diameter. The clip has an eccentricity greater progress retractable wall was installed using round holes 16 on the horizontal ends of the box-shaped outer wall and connected with the inner wall of the through oblong holes 17 on its limb with the ability to push and pull the latest.Both walls of the valve are mounted with a possibility when the population is as follows.In the closed position of the valve 2 by means of a hook 6 fixed to the front end of the holder 5. Inner wall 12 and outer wall 11, Repartee springs 9, are drawn to the mated surfaces of the circuit 1 without a gap around the perimeter. By performing a sliding inner wall limited progress pinched falling flaps contour excluded, because the force of friction from the preload of the walls 11, 12 to the circuit in comparison with the weight of the valve is small, and the efforts of the springs through the axis 14 are closed at the ends of the oblong holes 15, which limit the spreading of the walls.For opening the valve includes an electromagnet 4. When the anchor from engagement with the holder 5 is overcome the frictional force generated partial weight of body. Another friction force created by the compression spring, when the wall rasperry, supports the valve on weight, due to this, the load on the electromagnet is reduced.When disengagement of the holder from the hook 6, the flap falls under its own weight and maintained by the limiter circuit 18 move down. Drop valve is retarded by the spring 9, which, as well as shock absorber 19 the impact of the fall is softened.Opening the valve manually by turning the covered position, the flap is lifted manually. So that the friction force created by the compression springs, not resisted, wall pull together with the help of an eccentric clamp 10 by turning the lever 20 at an angle of 180o. Due to the eccentric connection of the clip with the inner wall of the through oblong holes 17 pinched eccentric on the limb 13 when translating clip from one position to another are excluded.When communicating the valve with bevel 7 drive box deviates from it to align the holder with the hook, then returns to the starting position, the flap hangs on the front end of the holder, and an eccentric clamp means to its original position. As the clip is the eccentricity, the greater the stroke of the inner wall, the Cam inside the oval hole is placed with a gap that prevents the springs to shore the walls to bring them closer to the path closely.Under the action of compression spring inner wall extends, moving through the axes until the end of the oblong hole, and stops. These holes restrict the movement of the wall, as well as the strength of contraction of the walls of the path during straightening springs.In the contact surface of the inner wall with paired with it the surface of contronceni.Since the outer and inner walls rasperry elastic elements of the same effort, the result of the contact surface of the outer wall with paired with her surface contour formed additional sealing zone 22, which creates additional gapless resistance demoralizing.Shock absorber - rubber or felt gaskets form a seal the sides of the box-shaped wall.According to the variant of Fig. 5 during a fire at education through cracks on the inner wall 12 of the smoke lingers outer wall 11 is connected with the inner wall of the through limb 13 around the perimeter. Preload the inner wall to the circuit by means of an elastic element 9, two of which are attached to the loop at the top, and the other two attached to the flap at the bottom. Such a fixing elastic elements allows you to move the valve without preload it to the loop on the larger roads and thereby facilitates lifting the flaps in original closed position manually.Feasibility the ability of the claimed invention in comparison with the prototype is to provide improved operational characteristics of the device by creating mezzatorre, contains circuit, mounted on the opening of the exhaust shafts, a valve mounted for movement along the opening on the vertical guides placed in the box drive electromagnet holder, which is connected through a hook with flap and having a bevel on the front end, the hinge manual opening of the valve and seal, characterized in that it is provided with a compression spring and an eccentric clamp, and the flap is made in the form of a box-shaped outer wall and a retractable inner wall limited progress, rasperry compression springs, while the inner wall has a limb along the top and bottom edges and attached to the limb axis, through which it is connected with the outer wall through the elongated through holes on its sides, eccentric clamp has eccentricity, the greater the progress retractable wall was installed using round holes on the horizontal ends of the box-shaped outer wall and connected with the inner wall of the through oval holes on the limb, and both walls are mounted with the possibility to fit each of them to a suitable mating surface contour assasino.
