The utility model relates to an anti-explosion valve, which comprises a valve seat 1, a corrugated tube 2, a corrugated tube flange 3, an anti-explosion sheet 4, an anti-explosion sheet tightening flange 5, a pricking pin 6 and a bracket 7, wherein an external pipeline can be mounted on the valve seat 1, so as to derive pressure-relieving materials; one end of the corrugated tube 2 is mounted on the valve seat 1; the valve seat 1 is used for mounting equipment; the corrugated tube flange 3 is mounted at the other end of the corrugated tube 2; the anti-explosion sheet 4 is tightened between the corrugated tube flange 3 and the anti-explosion sheet tightening flange 5; the pricking pin 6 is mounted on the bracket 7, so as to adjust the stretching length of the pricking pin; and the bracket 7 is mounted on the valve seat 1. The pressure inside a cavity formed by the corrugated tube 2 and the anti-explosion sheet 4 is the same as that inside the equipment; the corrugated tube 2 can perform telescopic movement under the action of the pressure; with the stretching of the corrugated tube 2, the anti-explosion sheet 4 is close to the tip of the pricking pin 6, when the pressure is large enough, the pricking pin 6 pricks the anti-explosion sheet 4 to break, and the pressure inside the equipment is released. In order to enable the anti-explosion valve to adapt to high pressure, a spring 8 can be further mounted between the ant-explosion sheet tightening flange 5 and the bracket 7.
Description
Technical field
The utility model relates to a kind of explosion-proof valve, and explosion-proof valve is installed on equipment or the pipeline, when equipment or manifold pressure surpass safety pressure, by explosion-proof valve device for discharging or pipeline pressure, prevents the superpressure explosive accident.
Background technique
The burst disk of common explosion-proof valve by the withstand voltage limit of self material, realizes overpressure failure, the release device mesohigh.Safety rate by the quality of burst disk, is not very reliable fully.Pressure fixing does not simultaneously have selectivity.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of new type explosion proof valve simple in structure.Having solved and used common explosion-proof valve safety rate fully by the quality of burst disk, is not very reliable.Pressure fixing does not simultaneously have optionally problem.The utility model explosion-proof valve adopts the passive mode that punctures of 6 pairs of burst disk 4 of pricker.Reduced the material requirement to burst disk 4, the passive mode that punctures is safe and reliable.Pricker is adjustable, and a cover diaphragm can be suitable for various pressure, has reduced the selection to burst disk 4.In order to solve the high pressure application, the utility model is mounting spring 8 between burst disk clamp flange 5 and support 7 also, makes explosion-proof valve can be fit to higher pressure.
A kind of implementation of the utility model explosion-proof valve is the explosion-proof valve that explosion-proof valve is made up of valve seat 1, bellows 2, bellows flange 3, burst disk 4, burst disk clamp flange 5, pricker 6 and support 7.On the valve seat 1 outer pipeline can be installed, derive the release material.One end of bellows 2 is installed on the valve seat 1, and valve seat 1 is used for and equipment is installed, and the other end of bellows 2 is installed bellows flange 3, and burst disk 4 is fastened between bellows flange 3 and the burst disk clamp flange 5; Pricker 6 is installed on the support 7, can regulate the pricker extrusion; Support 7 is installed on the valve seat 1.Bellows 2 is interior identical with the equipment internal pressure with the cavity that burst disk 4 forms, and under pressure, bellows 2 is done fore and aft motion, along with bellows 2 elongations, burst disk 4 is near the tip of pricker 6, when pressure is enough big, pricker 6 punctures burst disk 4, and burst disk 4 is broken, and discharges the pressure in the equipment.In order to make explosion-proof valve be fit to high pressure, the utility model can also be between burst disk clamp flange 5 and support 7 mounting spring 8, make explosion-proof valve can be fit to higher pressure.
The another kind of implementation of the utility model explosion-proof valve is the explosion-proof valve that explosion-proof valve is made up of valve seat 1, bellows 2, bellows flange 3, burst disk 4, burst disk clamp flange 5, pricker 6, support 7 and spring 8.One end of bellows 2 is installed on the valve seat 1, and valve seat 1 is used for and equipment is installed, and the other end of bellows 2 is installed bellows flange 3, and burst disk 4 is fastened between bellows flange 3 and the burst disk clamp flange 5; Pricker 6 is installed on the support 7, can regulate the pricker extrusion; Support 7 is installed on the valve seat 1.Bellows 2 is interior identical with the equipment internal pressure with the cavity that burst disk 4 forms, and spring 8 is installed between burst disk clamp flange 5 and the support 7; Under pressure, bellows 2 overcomes the elastic force of spring 8 and does fore and aft motion, and along with bellows 2 elongations, burst disk 4 is near the tip of pricker 6, and when pressure was enough big, pricker 6 punctured burst disk 4, and burst disk 4 is broken, and discharges the pressure in the equipment.Because the effect of spring 8 makes explosion-proof valve can be fit to higher pressure.
