Description
Technical field
The present invention relates to gas technical field of fire control, and in particular to a kind of gas fire-fighting flame proof valve.
Background technique
Dust at present explosion easily occurs in grain and agricultural product dust, metallic dust, coal dust, pharmaceutical engineering powder, petroleum
The industries such as mechanical ash, textile industry fiber, timber processing.With the hair of production-scale continuous expansion and powder retrofit
Multiple trend is presented in the dust explosion accident of exhibition, China.On August 2nd, 2014, Fauna of Kunshan, Jiangsu Zhong Rong metal product Co., Ltd hair
Raw especially great aluminum dust explosion accident, eventually leads to that 146 people are dead, 258 people are injured, and 3.51 hundred million yuan of direct economic loss.For
The generation of fire and explosion accident is prevented, national departments concerned requires these workplaces that should take stringent explosion precaution.Flame proof
Valve is anti-by special designing, and pressure wave and flame can be stopped to spread to it along pipe laying from the process equipment of dust explosion
The destroying infection that its process equipment generates will lose by explosion partition in part caused by inevitable dust explosion accident
It is preferably minimized.
Application No. is the patents of CN201710160378.1 to disclose a kind of unidirectional flame proof valve open in usual, it is characterised in that：
Including valve body, flap, magnet, deflector, pipe flange, the deflector is connected on the flap, the pipe flange includes tube method
Blue inclined-plane, the flap are acted on by magnet being attached together with magnet under normal conditions, and far from the pipe flange inclined-plane, when quick-fried
When fried generation, the flap is pushed deflector and flap by explosion wave percussion, so that flap and the pipe flange
Inclined-plane fitting, forms mechanical seal, and the unidirectional flame proof valve is closed.Although this patent can separate explosion generate shock wave and
Flame, prevents subsequent explosion, but for convenience of explosion time, shock wave by flap and feed pipe mechanical seal, flap and into
Angle between expects pipe only has 20-30 °, to can stop dust, influences transport of the dust in flame proof valve.
Summary of the invention
Based on the above technical problem, the present invention provides a kind of gas fire-fighting flame proof valves, thus solve it is existing unidirectionally every
Quick-fried valve influences the technical issues of dust transport.
The technical solution adopted by the present invention is as follows：
A kind of gas fire-fighting flame proof valve, including shell, shell both ends are respectively arranged with feed pipe and discharge nozzle and are used for
Open and close the flap of feed pipe；Described flap one end is provided with rotation axis, and flap can rotate around rotation axis and realize feed pipe and open and close；
The flap is metallicl magnetic material, and inner walls are provided with the magnet that can adsorb flap,
The shell is located at flap top and is provided with gas fire department, and gas fire department lower part is provided with gas outlet,
Gas outlet is located above flap；One end that discharge nozzle is located at opposite flap is provided with temperature inductor, and temperature inductor, gas disappear
Anti- mechanism is connect with control system.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1, fire fighting gas of the present invention can not only put out a fire, but also gas fire department gas outlet is located above flap, quick-fried
When fried, temperature inductor detects that temperature increases, and then controls fire department by control system and discharges fire-fighting to enclosure interior
Gas, fire fighting gas impact flap, are closed flap rotation with feed pipe, therefore flap is in normal work, can be with
It is horizontal positioned, it avoids influencing dust transport；
2, fire fighting gas impacts flap, after connecting flap with feed pipe, the shock wave for generation of exploding further with valve
Valve contact, is completely embedded flap with feed pipe, and the shock wave and flame for avoiding explosion from generating are propagated by pipeline toward upstream, keeps away
Exempt to generate subsequent explosion；
3, one end that discharge nozzle is located at opposite flap is arranged in temperature inductor, is detecting explosion at the first time, is making to disappear
Anti- gas has enough time so that flap closes feed pipe；And when shock wave is run in shell, there is enough disappear
Anti- gas is buffered and is put out a fire.
Preferably, the flap, which is located at, is provided with buffer board with feed pipe contact position, is arranged between buffer board and flap
There are multiple buffer units；Each buffer unit includes the spring of multiple coaxial arrangements, and multiple springs in same buffer unit are high
Degree is all different；
The feed pipe is located at flap one end outer circumference surface and is provided with multiple elastic rods, and elastic rod position is corresponded on flap and is set
Multiple fixation holes are equipped with, elastic rod cooperates with fixation hole connect flap and feed pipe；
It is inclined-plane at the top of the elastic rod, inclined-plane is arranged in flap side, so that flap be made to connect with feed pipe
Cheng Zhong depresses elastic rod.
Buffer board is provided on flap, when flap is connect with feed pipe, charging tube end can compress buffer board, thus
It protrudes into inside flap, increases the leakproofness between flap and feed pipe, and buffer board is internally provided with buffer unit, it can be right
Impact force is buffered, and flap is avoided to damage, and the spring heights in same buffer unit are different, to buffer in buffer board
When, buffer unit carries out multi-buffer to buffer board, and flap is allow to bear higher impact force；
When flap is connect with feed pipe, the fixation hole cooperation in elastic rod and flap being arranged on feed pipe can make
Flap connects firmer with feed pipe, and when flap being avoided to connect with feed pipe, flap is thrown open by suction function.
Preferably, the fixation hole is through-hole, to can directly pass through fixation when separating flap with feed pipe
The elastic rod being stuck in fixation hole is shunk in hole, so that flap and feed pipe conveniently be made to separate；
Preferably, multiple springs in the same buffer unit are set gradually from inside to outside, and multiple spring heights are from interior
It is sequentially increased outward, to not only allow buffer unit carry out multi-buffer to buffer board, but also spring heights are from inside to outside
It is sequentially increased, makes the spring highest of outermost, avoid most intermediate spring heights highest, in buffering, since middle springs are straight
Diameter is too small to cause spring to bend, and influences buffering effect；
Preferably, the magnet and flap relatively rotate one end of axis and connect, thus make the tie point of magnet and flap away from
Flap center of gravity farther out, reduces the burden of magnet.
