The smoke removal device

 

(57) Abstract:

The invention relates to a device for removing smoke from the floors of the building through openings in the wall of the exhaust shafts. The device contains a circuit, the valve driving magnet holder, a return spring and hinge manual opening of the valve. The electromagnet holder and the recoil spring is accommodated in a box. The holder is connected through a hook with flap and with the armature of an electromagnet. The hinge is fixed on a circuit above the opening. The box is hinged on the hinge and the flap on the front end of the holder along the axis of the center of gravity. At the ends of the valve and the circuit made the tabs. In the closed position of the valve and the circuit form a labyrinth seal with two steps. The formation of complex shapes gap creates resistance to demoralizing. The device has an elastic sealing elements in the form of petals. The petals are attached to the circuit on the perimeter with the possibility of contact with the sealing surfaces of the valve. The technical result is improved performance. 3 Il.

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 the possibility of moving along the opening on the vertical guides, the drive magnet holder, which is connected through a hook on the valve and armature of the electromagnet, and the seal /A. with. The USSR 1298494, CL E 24 E 13/08, 1984).

In this device, the seal may melt, causing sticking of the valve in the circuit.

The damper is fixed to the holder by means of a hook-hooks console that leads to deviations from the contour of the sealing surfaces of the valve, education direct gaps. This reduces the resistance demoralizing.

The closest in technical essence is the smoke removal device containing a valve mounted to move along the opening on the vertical guides placed in the box drive electromagnet holder, which is connected through a hook on the valve and armature of the electromagnet and having a bevel on the front end, a return spring, and a hinge manual opening of the valve (Patent RU N 2111802, class B 08 B 15/00, 1992 - prototype).

In this device, the sealing surfaces of the valve are prevented from contact with the circuit as it is moved along the vertical guide rails by means of wheels and flanged rollers.

Formed by the walls of the valve and loop gap Charonne characteristics of the device.

The objective of the invention is to provide improved operational characteristics of the device by creating significant resistance to demoralizing.

For this unit, smoke, containing a valve mounted to move along the opening on the vertical guides placed in the box drive electromagnet holder, which is connected through a hook on the valve and armature of the electromagnet and having a bevel on the front end, a return spring, and a hinge manual opening of the valve, has a labyrinth seal at least two stages formed by the tabs on the ends of the valve and circuit, and an additional elastic sealing elements in the form of petals, which are fixed on the circuit around the perimeter with the possibility of contact with their grooved edges with the sealing surfaces of the valve, when this hinge manual opening of the valve is fixed on a circuit above the opening along the symmetry axis, and the drive box is connected to hinge not on the axis of the center of gravity can be rotated around the hinge preload valve to the elastic petals, and the holder is connected through a hook with the flap not along the axis of the center of gravity of the latter, and with an anchor - posledstviya smoke, front view of Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 1.

The smoke removal device contains a circuit 1 mounted on the opening, the valve 2 is installed to move along the opening on the vertical guides, placed in box 3, the drive electromagnet 4, the holder 5, which is connected through a hook 6 with the valve and armature 7 of the electromagnet and having a bevel 8 on the front end and a return spring 9. The spring is mounted on the holder axis and has a common focus 10. It also contains a hinge 11 manual opening of the valve.

The device has a labyrinth seal 12 in at least two stages. Steps are formed by the protrusions 13 and 14 located at the ends of the valve and circuit. Lateral protrusions serve as vertical guides for moving the valve. It additionally has an elastic sealing elements in the form of petals 15. The petals are attached to the circuit on the perimeter with the possibility of contact with their grooved edges with sealing surfaces 16 of the flap.

The hinge 11 manual opening of the valve is fixed on the circuit over the aperture on the axis of symmetry /Fig. 1/. When this drive box 3 is connected to hinge not on the axis center is Zan through the hook 6 with the flap not along the axis of the center of gravity of the latter.

The smoke removal device works 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, the other end of the holder is connected with the armature of the electromagnet 4 by radial surfaces 17.

The tabs 13, 14 at the ends of the flaps 2 and loop 1, when the opening is closed, form a labyrinth seal 12 in at least two stages. Formed by the complex shape of the gap has a significant resistance demoralizing.

Elastic sealing elements in the form of petals 15, which is fixed on a circuit around the perimeter with the possibility of contact with their grooved edges with sealing surfaces 16 of the valve to generate resistance to demoralizing additionally.

For opening the valve includes an electromagnet. When the anchor from engagement with the holder overcome the frictional force created by the weight of the flap.

The elastic force of the petals and opposite force caused by displacement of the axis of the center of gravity of the drive box and the damper support the latest on weight, due to this, the load on the holder is reduced, the operation of the electromagnet is facilitated, and the reliability of operation is increased, radial power the electromagnet and with a hook damper preload valve to the petals falling, the flap falls under its own weight and maintained by the limiter circuit 18 move down. The impact of the fall damper is softened due to the shock absorber, such as a rubber plate 19 fixed to the base circuit. In reverse starting position holder is rotated about its axis to another by means of a return spring 9. The electromagnet turns off the microswitch /not shown/, which is also placed in the box 3.

Opening the valve manually by turning on the drive itself boxes around the axis of the hinge to the full release of the holder from engagement with the flap.

In closed position the flap is lifted manually. When communicating the valve with bevel 8 drive box 3 deviates from it to align the holder with the hook, then returns to the starting position, the holder is in the depths of a hook and flap hangs on the front end of the holder along the axis of the center of gravity.

Samosatene occurs without intervention, which is useful for periodic health checks of the device.

Feasibility the ability of the claimed invention in comparison with the prototype is to provide an improvement which P CLASS="ptx2">
