The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of kitchen guarding with dual fire-proof function uses the smoke discharging valve, comprise valve casing 1, junction plate 2, the inner chamber of valve casing 1 can be cylindrical, the cuboid or the square bodily form, valve casing 1 is provided with inlet end 3 and outlet side 4, valve casing 1 links to each other with junction plate 2, junction plate 2 links to each other with building exhaust passage wall 9, outlet side 4 is passed junction plate 2 and is arranged in building exhaust passage 5, inlet end 3 links to each other with indoor exhaust pipeline 6, tilting in valve casing 1 have a retaining wall 8, retaining wall 8 is provided with steam vent 16, non-return valve block 11 is journaled on the non-return valve shaft 10, the lower end of non-return valve block 11 contacts with retaining wall 8 and cover steam vent 16 under action of gravity, realize check function, after 10 rotations of non-return valve shaft, open steam vent 16 under the effect of the wind-force that non-return valve block 11 is carried in indoor exhaust pipeline 6, realize the smoke evacuation function, fire prevention valve block 13 is suspended in the valve casing 1 under the effect of fire prevention valve shaft 12 and fuse 14 and is positioned at the top of steam vent 16, be set with torsion spring 15 on the fire prevention valve shaft 12, one end of torsion spring 15 offsets with fire prevention valve block 13, one end of fuse 14 links to each other with the inner chamber of valve casing 1, the other end links to each other with fire prevention valve block 13, after fuse 14 fusing, fire prevention valve block 13 rotates around fire prevention valve shaft 12 under the effect of torsion spring 15, cover on non-return valve block 11 and until fire prevention valve block 13 glands, realize dual fire-proof function steam vent 16.
For the ease of the replacing of fuse 14, inlet end 3 can be linked to each other with cover plate 7, cover plate 7 links to each other with valve casing 1, only cover plate 7 is pulled down from valve casing 1 when changing fuse 14, hand can be stretched in the valve casing 1 and change easily.If inlet end 3 is directly linked to each other with valve casing 1, so also can when changing fuse 14, directly will be sleeved on after air duct 6 on the inlet end 3 takes off, put in the valve casing 1 with hand and change, also more convenient.
In addition, the also available stage clip of torsion spring 15 replaces, and an end of stage clip links to each other with catch wall 8 or valve casing 1, and the other end offsets with fire prevention valve block 13.
Fuse 14 can be fusible link or fuse link during concrete enforcement, can bear certain pulling force under its normal condition, automatic disconnection when reaching fusing point (about 70 ℃), thus the depression bar 15 that is attached thereto is fallen under action of gravity.
The size of each parts should accurately design during concrete enforcement, interferes preventing.
The course of work of the present utility model is;
When indoor exhaust wind equipment is worked, non-return valve block 11 turns to equilibrium state around non-return valve shaft 10 automatically under the effect of wind-force, the steam vent 16 of flue gas from retaining wall 8 enters the outlet side 4, and by the building exhaust passage 5 enter in the atmosphere, and the valve block 13 of preventing fires this moment is in suspension status under the effect of fuse 14, can not influence the air draft effect, when indoor exhaust equipment quits work, non-return valve block 11 is closed steam vent 16 (this be because the position of non-return valve shaft 10 on the top of the center of gravity of valve block 10) automatically under the effect of gravity, play anti-collaborating effect, the flue gas of other user's discharge can not inlet chamber in.
When naked light takes place when, temperature in the building exhaust passage 5 rises rapidly, when the fuse 14 that is positioned at valve casing 1 is sensed fire temperature, and when reaching its fusing-off temperature (being generally 70 ℃), fuse 14 automatic disconnections, at this moment, the rotation rapidly under torsion (pressure) effect of gravity and torsion spring 15 (or stage clip) of fire prevention valve block 13, and be pressed on the non-return valve block 11, make non-return valve block 11 cover on steam vent 16 and compress, make them can not be around 10 rotations of non-return valve shaft, under the double action of fire prevention valve block 13 and non-return valve block 11, high-temperature flue gas or naked light can not reach the fireproof purpose in steam vent (16) inlet chamber.As shown in Figure 2.
When needs are changed fuse 14, as long as cover plate 7 is pulled down from valve casing 1, just hand can be stretched in the valve casing 1, take off the fuse 14 that has fused, again change new fuse 14, the torsion that fuse 14 overcomes torsion spring 15 makes fire prevention valve block 13 leave steam vent 16, guarantees the unimpeded of normal smoke discharging passage.
