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 exhibition, the dust explosion accident in China.On August 2nd, 2014, Fauna of Kunshan, Jiangsu Zhong Rong metal products Co., Ltd hair
Raw especially great aluminum dust explosion accident eventually leads to 146 people death, 258 people injury, 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 prevented through special designing, can stop that pressure wave and flame spread to it from the process equipment of dust explosion along pipe laying
The destroying infection that its process equipment generates separates explosion in part, will loss caused by inevitable dust explosion accident
It is preferably minimized.
Patent application No. is CN201710160378.1 discloses 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 is under normal conditions by magnet effect together with magnet adsorption, and the separate pipe flange inclined-plane, when quick-fried
During fried generation, the flap is pushed deflector and flap by explosion wave percussion so that flap and the pipe flange
Inclined-plane is bonded, and 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 shock wave and flame are when impacting flap, it may appear that due to shock wave and fire
Flame power is excessive, and flap is caused to damage, and prevents flap and feed pipe from sealing, it is impossible to play the role of flame proof.
Utility model content
More than technical problem is based on, the utility model provides a kind of unidirectional flame proof valve of resistance to deformation, existing so as to solve
The technical issues of flame proof valve flap is easily damaged by shock wave and flame impingement, leads to that flame proof cannot be played the role of.
The technical solution adopted in the utility model is as follows：
A kind of unidirectional flame proof valve of resistance to deformation, including housing, housing both ends are respectively arranged with feed pipe and discharge nozzle and use
In the flap of folding feed pipe；Described flap one end is provided with rotation axis, and flap can rotate around rotation axis and realize feed pipe and open
It closes；The flap is metallicl magnetic material, and inner walls are provided with the magnet that can adsorb flap, and the angle that flap is opened is
20°-30°；
The flap is located at is provided with buffer board with feed pipe contact position, is provided between buffer board and flap multiple slow
Flushing device；Each buffer unit includes the spring of multiple coaxial arrangements, the not phase of multiple spring heights in same buffer unit
Together；
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 mounting holes are equipped with, elastic rod coordinates with mounting 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 as to which flap be made to be connect with feed pipe
Cheng Zhong depresses elastic rod.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, buffer board is provided on the utility model flap, when flap is connect with feed pipe, charging tube end can press
Contracting buffer board so as to stretch into inside flap, increases the leakproofness between flap and feed pipe, and buffer board be internally provided with it is slow
Flushing device can avoid flap from damaging to impact force into row buffering, and the spring heights in same buffer unit are different, so as to
When buffer board buffers, buffer unit carries out multi-buffer to buffer board, and flap is allow to bear higher impact force；
2nd, the utility model is when flap is connect with feed pipe, the mounting hole in elastic rod and flap set on feed pipe
Cooperation, can be such that flap is connected with feed pipe firmer, and when avoiding the flap from being connect with feed pipe, flap is unexpected by suction function
It opens.
Preferably, the mounting hole is through-hole, so as to when flap is separated with feed pipe, can directly pass through fixation
The elastic rod being stuck in mounting hole is shunk in hole, so as to separate conveniently flap and feed pipe；
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, so as to which buffer unit not only be allow to 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 relatively rotates one end of axis with flap and connect；So as to make the tie point of magnet and flap away from
Flap center of gravity farther out, reduces the burden of magnet.
