Description
Technical field
The utility model is related to a kind of explosion venting valves, are mainly used in gas driven generator technical group field.
Background technology
The problems such as gas driven generator group inevitably occurs tempering, blows out in the process of running, serious tempering is put
Big gun can cause the damage of the equipment such as air filter, silencer, waste heat boiler, not only influence the safe and stable operation of unit, even
Serious economic loss and casualties can also be caused.Therefore, it is installed on gas driven generator group air inlet pipeline and smoke-exhaust pipeline
Explosion venting valve is the necessary means for ensureing unit safety stable operation.After installing explosion-proof valve, high temperature and high pressure gas can be in time from venting of dust explosion
It is released at valve, avoids the generation of bad accident.
Currently, gas driven generator group technical disadvantages existing for inlet and outlet pipeline explosion venting valve：1, the sealing cover of explosion venting valve with
Without sealing material between valve body, the pressing force against sealing cover is sealed, and be easy to cause leakage；2, explosion venting valve sealing cover uses
The mode of spring straining or compression be mounted on valve body on, when unit tempering, blow out energy it is big when easily cause spring excessive tensile
Or compress and fail, or even beat winged sealing cover；Using counterweight sealing cover when, explosion venting valve open when be easy to cause limit failure or
The problems such as person's rotation axis falls off leads to venting of dust explosion defective valve.
Utility model content
The technical problems to be solved in the utility model is：A kind of gas driven generator group inlet and outlet pipeline explosion venting valve is provided,
It under the premise of realizing venting of dust explosion function, while solving the problems such as explosion venting valve seal failure, security reliability is low, ensures gas power generation
The safe operation of unit.
Explosion venting valve described in the utility model, including valve body, valve body are set as the shell of both ends open, are arranged in valve body and live
Plug, piston are set as the shell of bottom opening, and connecting flange is arranged in valve body top, and mounting flange, connecting flange top is arranged in lower part
Portion connects stop flange, and the medial surface of mounting flange is arranged sealing element, venting of dust explosion hole, venting of dust explosion hole is distributed on the side wall of valve body lower portion
Positioned at the top of mounting flange, male half coupling is arranged in mounting flange medial surface, sealing ring is arranged in male half coupling, sealing ring is adhered to convex
Stop portion.
Sealing ring can be heat safe rubber seal, and heat safe rubber seal is bonded between piston and mounting flange
Circle, ensure that the sealing reliability of explosion venting valve in unit normal course of operation；When unit is tempered, blows out, high pressure draught will live
Plug jacks up upwards, is limited by stop flange, limiting device is reliable；Conducted oneself with dignity by piston and realize and reset, reset it is simple, can
It leans on.
The piston includes the cylinder of both ends open, and top end plate and bottom end plate, bottom is respectively set in cylinder both ends
End plate corresponds to male half coupling setting groove.
It is solid by fastener that gasket, connecting flange and stop flange are set between the connecting flange and stop flange
It is fixed.
The connecting flange and mounting flange is welded to the both ends of valve body.
The valve body and piston is disposed as cylindrical housings.
Assembled explosion venting valve is vertically mounted to the inlet and outlet pipeline of gas driven generator group on dress flange.Unit is just
Often when operation, piston realizes that the compression between its bottom end plate and sealing ring seals by dead weight；When unit occur tempering or
When blowing out, high temperature, high pressure air-flow piston is jacked up upwards, rest at stop flange, be tempered, blow out the high pressure draught of generation
Venting of dust explosion is then realized by the window that valve body lower portion opens up；After the completion of venting of dust explosion piston by conduct oneself with dignity self-return, again realize with it is close
Sealing between seal.
The utility model has the beneficial effects that：
By the anti-venting of dust explosion valve arrangement of Curve guide impeller, the purpose of smooth venting of dust explosion is not only realized, and avoid leakage problem
With returning device Problem of Failure.Improve the reliability and service life of explosion venting valve.

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1~Fig. 2, explosion venting valve described in the utility model, including valve body 4, valve body 4 are set as both ends open
Shell, valve body 4 is interior to be arranged piston 3, and piston 3 is set as the shell of bottom opening, and connecting flange 8 is arranged in 4 top of valve body, and lower part is set
Mounting flange 1 is set, 8 top of connecting flange connects stop flange 10, and sealing element, 4 lower part of valve body is arranged in the medial surface of mounting flange 1
Side wall on be distributed with venting of dust explosion hole 6, venting of dust explosion hole 6 is located at the top of mounting flange 1, and male half coupling 5 is arranged in 1 medial surface of mounting flange,
