Abstract
The present invention relates to a kind of pressure-relief anti-explosion valve, it comprises and sealing mutually and the flange be fixedly connected with the equipment that there is hidden peril of explosion, be covered in the sealing cover on flange and be installed in sealing cover and the explosion proof door be covered on the center hole border of flange, explosion proof door comprises at least one and to be connected between sealing cover and flange and perpendicular to the guide rail of flange, the spring being flicked the explosion proof door body of pressure release when equipment internal pressure is excessive and the center hole border of explosion proof door body and flange is tightly connected, explosion proof door body to be slidably connected on guide rail and to be covered on the center hole border of flange.The present invention utilizes spring, and by explosion proof door, this is connected with flange seal, when equipment internal pressure is excessive, explosion proof door this flicked rear rapid reset, prevent air from entering, avoid secondary explosion, can Reusability, because it relies on the elastic force of spring to be pushed against on flange, no matter how it is installed on equipment can use, and application area is wider.
Description
Technical field
The present invention relates to field of explosion, particularly a kind of pressure-relief anti-explosion valve.
Background technique
Existing explosion-proof valve has two kinds, and one makes explosion proof door be covered in air outlet by gravity, and another kind arranges burst disk in air outlet.The first explosion-proof valve due to its explosion proof door be rely on gravity be sealed on air outlet, so its mounting type can be restricted, its application area is comparatively limited to; And the second explosion-proof valve is disposable products due to burst disk, all need after each pressure release to change burst disk, use comparatively inconvenience.
Summary of the invention
The object of this invention is to provide one can recycle and widely used pressure-relief anti-explosion valve.
For achieving the above object, the technical solution used in the present invention is: a kind of pressure-relief anti-explosion valve, it comprises and sealing mutually and the flange be fixedly connected with the equipment that there is hidden peril of explosion, be covered in the sealing cover on described flange and be installed in sealing cover and the explosion proof door be covered on the center hole border of described flange, described explosion proof door comprises at least one and to be connected between sealing cover and flange and perpendicular to the guide rail of flange, the spring being flicked the explosion proof door body of pressure release when equipment internal pressure is excessive and the center hole border of explosion proof door body and flange is tightly connected, described explosion proof door body to be slidably connected on described guide rail and to be covered on the center hole border of described flange.
Optimize, be also provided with seal ring between described explosion proof door body and flange, the seal groove that described seal ring comprises the center hole border being fixed on flange and the sealing gasket be arranged in seal groove.
Optimize, spring can adopt helical spring or turriform spring.
Optimize, the described flange side of being annular or ring, described sealing cover is cuboid shape or hemisphere type.
Optimize, described explosion proof door body comprises metal material is made.
Because technique scheme is used, the present invention compared with prior art has following advantages: the present invention utilizes spring, and by explosion proof door, this is connected with flange seal, when equipment internal pressure is excessive, explosion proof door this flicked rear rapid reset, prevent air from entering, avoid secondary explosion, can Reusability, because it relies on the elastic force of spring to be pushed against on flange, no matter how it is installed on equipment can use, and application area is wider.
Accompanying drawing explanation
The structural representation of pressure-relief anti-explosion valve of the present invention when accompanying drawing 1 is normal pressure in embodiment one;
The structural representation of pressure-relief anti-explosion valve of the present invention when accompanying drawing 2 is pressure release in embodiment one;
In above accompanying drawing: 1, flange; 2, sealing cover; 3, explosion proof door; 31, guide rail; 32, explosion proof door body; 33, spring; 41, seal groove; 42, sealing gasket.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one
As shown in Figure 1, pressure-relief anti-explosion valve comprises flange 1, sealing cover 2 and the explosion proof door 3 be arranged between flange 1, sealing cover 2 and the seal ring between explosion proof door 3 and flange 1.In the present embodiment, explosion proof door comprises two springs 33 being symmetricly set on guide rail 31 between flange 1 and sealing cover 2, being covered in the explosion proof door body 32 on the center hole border of flange 1 and explosion proof door body 32 is tightly connected with the center hole border of flange 1, and spring 33 to be arranged between explosion proof door body 32 and sealing cover 2 and to be in compressive state; The seal groove 41 that seal ring comprises the center hole border being fixed on flange 1 and the sealing gasket 42 be arranged in seal groove 41.
The equipment that there is hidden peril of explosion sets out pore, and flange 1 is square flange, and the cross section of sealing cover 2 is also square, and flange 1 is sealedly attached to the border of air outlet hole, and sealing cover 2 is sealed on the periphery of flange 1, blocks air outlet hole.
Vertical flanges 1 of two guide rails 31 and lay respectively at the both sides of flange 1 center hole, the thickness of explosion proof door body 32 is not limit, choose 10mm in the present embodiment, explosion proof door body 32 is slidably connected on guide rail 31, when equipment internal pressure is excessive, explosion proof door body 32 flicks by the gas in equipment, after pressure release, the spring 33 be arranged between explosion proof door body 32 and sealing cover 2 is pushed back on sealing gasket 42, makes it reset rapidly, prevent air from entering, avoid secondary explosion.The impacting force of spring 33 pairs of explosion proof door bodies 32 can adjust according to the withstand voltage degree of equipment.Computational methods are as follows: the power that sets of setting pressure-relief anti-explosion valve to open is as F1, and meet the frictional force F2 of effect with guide rail, explosion-proof deadweight Mg, spring power when pressure-relief anti-explosion valve is P.Formula is as follows: when pressure-relief anti-explosion valve side fills: F1=P-F2; When pressure-relief anti-explosion valve is heavily directly installed: F1=P-Mg-F2.
Above-mentioned relate to parts except sealing gasket be that fireproof plastic glue material is made, all the other are metallic material and make.Because structure of the present invention is simple, make easily, be applicable to middle-size and small-size enterprise and produce.
Embodiment two
The difference of the present embodiment and embodiment one is: sealing gasket 42 and explosion proof door body 32 are fixedly connected, and itself and seal groove 41 match.During normal pressure, sealing gasket 42 is embedded in seal groove 41, and during pressure release, sealing gasket 42 ejects with explosion proof door body 32 and is separated with seal groove 41.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and the boundary dimension as changed flange, sealing cover and spring all should be encompassed within protection scope of the present invention.
