The smoke removal device
(57) Abstract:The invention relates to a device for removing smoke from the premises on the floors of the building through openings in the wall of the exhaust shafts. The device contains a circuit, the valve, vertical guide rods with thickened upper ends, the upper and lower strips, by means of which the flap is moved along the opening on the rods and in the closed position, tightened to the path. It also comprises a drive magnet holder in the form of a sprocket connected by a roller suspension with anchor and through hook - with flap and seal. It additionally has a locking spacer rods with nuts. Each rod is connected with the circuit by means of two brackets through their sleeve, which is fixed on the rod with both ends by means of nuts. In the closed position of the valve by means of a hook is held on the sprocket, and the sprocket from rotating around the axis of the frozen due to the roller suspender. When the electromagnet the armature out of engagement with an asterisk. Flap under its own weight, turning a star falls and is held on the basis of the circuit by means of the stroke limiter down. The technical result is blochstrasse to devices for removal of smoke from the premises on the floors of the building through openings in the wall of the exhaust shafts.You know the smoke removal device containing the circuit, a valve mounted for movement along the opening on the vertical guide rods by means of upper and lower clamps, the drive magnet holder, which is connected through a roller suspension with the armature of the electromagnet and through hook - with flap, and a sealing zone.with. The USSR 1298494, CL F 24 F 13/08, 1984 - prototype).In this device, the rigid fastening loop on the opening by welding causes distortion of the attachment plane on the installation. Which flap is adjacent to the path with gaps, which reduces the resistance demoralizing.The upper and lower clamps in the form of staples cover the rods with a gap. The clearance does not provide and, accordingly, do not press the flap firmly to the path. The penetration of smoke remains.The rubber seal may melt, causing sticking of the valve on the path to the formation of cracks.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 contai using the upper and lower clamps, the drive magnet holder, which is connected through a roller suspension with the armature of the electromagnet and through hook - with flap, and a sealing zone has at least two locking rod with spacer nut connected with the circuit by means of the brackets through their sleeve with lock nuts at both ends, and each vertical guide rod has a thickened upper end, and the transition between thin and thick part of the stem is made conical, the upper clamp through the two holes with spherical walls covers different diameters of both terminals alternately, and the lower spring clamp secured to the bottom flap with the opportunity to interact with the base path.The invention is illustrated by drawings, where Fig.1 shows a device smoke, front view; Fig.2 - the same, top view; Fig.3 - section a-a in Fig.1.The smoke removal device contains a circuit 1 mounted on the opening in the wall of the exhaust shafts, the valve 2 is installed to move along the opening on the vertical guide rods 3 by means of the upper clamp 4 and the lower clamp 5. It also contains the drive electromagnet 6, the holder 7, the associated chev star, installed on an axis for rotation in both directions. The sprocket relative to the vertical axis roller suspension (anchor) is asymmetrically.The attachment plane of the loop and flap provided with a heat-resistant sealing belt 10 in the form of a tube of oval profile with a possible elastic filler.The device has two locking rod 11 with the spacer nut 12. For wide openings, the number of terminals can be increased. Each rod is connected with the circuit by means of brackets 13 through the sleeve 14. The sleeve on the rod with both ends fixed by lock nuts 15.A vertical guide rod 3 has a thickened upper end. The transition between thin and thick part of the stem is made conical. The upper clamp 4 in the form of the strap through the two holes 16 with a spherical wall covers different diameters d and D both terminals alternately. And the lower clamp 5 in the form of spring strips secured to the bottom flap with the opportunity to interact with the base path.The smoke removal device works as follows.The circuit 1 at the aperture is fixed folding with lock rods C nuts utomlyayutsya respectively in the base and the ceiling opening, locking the rod in a vertical position. Thereafter, the sleeve 14 of each bracket 13 is fixed on the rod with both ends by means of nuts 15, and thereby the circuit is kept at the doorway.This consolidation does not transmits the force of tightening the nuts on the circuit that protects against warping the attachment plane. In addition, the locking rods can simplify the Assembly and disassembly of the device.When lifting the valve 2 in the initial closed position of the upper plate 4 through the openings 16 with a spherical wall slides without crushing the smaller diameter of the rod 3. When passing the strap through the cone to the larger diameter of the valve is pressed against the contour. At the end of the damper up the lower spring plank interacting with the base circuit, presses the valve to the path below. In all the closed flap is bogatoi to the path. In the closed position of the valve by means of a hook 9 is held on the sprocket 7, which itself against rotation around the axis is held with the help of roller suspension 8 mounted on the armature of an electromagnet 6.Execution holder in the form of stars provides samosatene valve without human intervention, which is useful when port with roller suspension bracket moves in a vertical direction until the roller beyond the depression of the sprocket. Then the flap under its own weight, turning through a hook star, falls and is held in the open position on the basis of the circuit by means of the upper clamping plate 4. The impact of the fall damper is softened due to the shock absorber 17.Feasibility the ability of the claimed invention in comparison with the prototype is to provide improved operational characteristics of the device by creating significant resistance to demoralizing. The smoke removal device containing the circuit, a valve mounted for movement along the opening on the vertical guide rods by means of upper and lower clamps, the drive magnet holder, which is connected through a roller suspension with the armature of the electromagnet and through hook - with flap, and a sealing zone, characterized in that it has at least two locking rod with the pressure nut connected with the circuit by means of the brackets through their sleeve with lock nuts at both ends, and each vertical guide rod has a thickened upper end, and the transition between thin and thick part of the rod is provided with a tapered, the upper hold-down means is Suginami clamp attached to the bottom flap with the opportunity to interact with the ground contour.
