Abstract
The invention relates to a pressure-relief anti-explosion valve comprising a flange, a sealing cap and an explosion door. The flange sealed with a device having explosion hazards is fixedly connected with the same, the sealing cap is sealed with the flange, and the explosion door is installed inside the sealing cap and sealed to the periphery of a center hole of the flange. The explosion door comprises at least one guide rail, an explosion door body and a spring. The guide rails vertical to the flange are connected between the sealing cap and the flange, the explosion door body is used for relieving pressure when the device is popped open due to large pressure inside, the spring is used for connecting the explosion door body and the periphery of the center hole of the flange in a sealed manner, and the explosion door body is slidably connected with the guide rails and sealed with the periphery of the center hole of the flange. Since the explosion door body and the flange are connected in a sealed manner by the spring, when the pressure inside the device is large, the explosion door body is restored rapidly after being popped open to prevent air from entering, and a secondary explosion is avoided; and the pressure-relief anti-explosion valve is pressed against the flange relying on elastic force of the spring, so can be used repeatedly on the device in any manner of installation, and is wide in application.
Description
Technical field
The present invention relates to explosion-proof field, particularly a kind of pressure-relief explosion-proof valve.
Background technique
Existing explosion-proof valve has two kinds, and a kind of is to make explosion proof door be covered in the air outlet by gravity, and another kind is in the air outlet burst disk to be set.First kind of explosion-proof valve is because its explosion proof door is to rely on gravity to be sealed on the air outlet, so its mounting type can be restricted, its application area is comparatively limited to; And second kind of explosion-proof valve all needs to change burst disk because burst disk is disposable products after each pressure release, uses comparatively inconvenience.
Summary of the invention
The purpose of this invention is to provide a kind of recycling and widely used pressure-relief explosion-proof valve.
For achieving the above object, the technical solution used in the present invention is: a kind of pressure-relief explosion-proof valve, it comprises the flange that seals mutually and fixedly connected with the equipment that has hidden peril of explosion, be covered in the sealing cover on the described flange and be installed in the sealing cover and be covered in explosion proof door on the center hole border of described flange, described explosion proof door comprises that at least one is connected between sealing cover and the flange and perpendicular to the guide rail of flange, the spring that is flicked the explosion proof door body of pressure release and the center hole border of explosion proof door body and flange is tightly connected when the equipment internal pressure is excessive, described explosion proof door body is slidingly connected on the described guide rail and is covered on the center hole border of described flange.
Optimize, also be provided with seal ring between described explosion proof door body and the flange, described seal ring comprises the seal groove of the center hole border of being fixed in flange and is arranged on the interior sealing gasket of seal groove.
Optimize, spring can adopt helical spring or turriform spring.
Optimize, the described flange side's of being annular or ring, described sealing cover are cuboid shape or hemisphere type.
Optimize, described explosion proof door body is made by metallic material.
Because technique scheme is used, the present invention compared with prior art has following advantage: the present invention utilizes spring, and this is connected with flange seal with explosion proof door, when the equipment internal pressure is excessive, reset rapidly after this quilt of explosion proof door flicks, prevent that air from entering, and avoids secondary explosion, can use repeatedly, because it relies on the elastic force of spring to push against on flange, no matter how it is installed on the equipment can both be used, and application area is wider.
Description of drawings
Accompanying drawing 1 is the structural representation of pressure-relief explosion-proof valve of the present invention during normal pressure among the embodiment one;
Accompanying drawing 2 is the structural representation of pressure-relief explosion-proof valve of the present invention during pressure release among the embodiment one;
In the 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 present invention is further described.
Embodiment one
As shown in Figure 1, the pressure-relief explosion-proof valve comprises flange 1, sealing cover 2 and is installed in explosion proof door 3 and the seal ring between explosion proof door 3 and flange 1 between flange 1, the sealing cover 2.In the present embodiment, explosion proof door comprises two springs 33 that are symmetricly set on guide rail 31 between flange 1 and the sealing cover 2, are covered in the explosion proof door body 32 on the center hole border of flange 1 and the center hole border of explosion proof door body 32 and flange 1 is tightly connected, and spring 33 is arranged between explosion proof door body 32 and the sealing cover 2 and is in compressive state; Seal ring comprises the seal groove 41 of the center hole border of being fixed in flange 1 and is arranged on sealing gasket 42 in the seal groove 41.
Exist on the equipment of hidden peril of explosion to set out pore, flange 1 is square flange, and the cross section of sealing cover 2 also is square, and flange 1 is sealedly attached to the border of air outlet hole, and sealing cover 2 is sealed on around the outer of flange 1, blocks air outlet hole.
Two guide rail 31 vertical flanges 1 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 slidingly connected on the guide rail 31, when the equipment internal pressure is excessive, gas in the equipment flicks explosion proof door body 32, after the pressure release, the spring 33 that is arranged between explosion proof door body 32 and the sealing cover 2 pushes back to it on sealing gasket 42, and it is resetted rapidly, prevent that air from entering, and avoids secondary explosion.The impacting force of 33 pairs of explosion proof door bodies 32 of spring can be adjusted according to the withstand voltage degree of equipment.Computational methods are as follows: establishing the setting power that the pressure-relief explosion-proof valve opens is F1, meets the frictional force F2 of effect with guide rail, and explosion-proof deadweight Mg, spring power when the pressure-relief explosion-proof valve is P.Formula is as follows: when pressure-relief explosion-proof valve side is adorned: F1=P-F2; When the pressure-relief explosion-proof valve weighs straight the installation: F1=P-Mg-F2.
The above-mentioned parts that relate to are made for the fire prevention plastic material except sealing gasket, and all the other are metallic material and make.Since of the present invention simple in structure, make easily, be fit to middle-size and small-size enterprise and produce.
Embodiment two
Present embodiment and embodiment's one difference is: sealing gasket 42 is fixedly connected with explosion proof door body 32, and itself and seal groove 41 are complementary.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 separates with seal groove 41.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention as changing flange, sealing cover and spring configuration size.
