According to the shocking burst diaphragm valve, the shape of a seal membrane and the position relationship between the seal membrane and the spray angle of a shocking burst pipe are set so that it can be ensured that a valve can be quickly and fully opened instantly after the shocking burst pipe detonates. The shocking burst diaphragm valve is characterized by comprising the shocking burst pipe, the valve, the seal membrane and a valve seat, the periphery of the seal membrane is clamped between the valve and the valve seat so that a channel formed by series connection of the valve and the valve seat can be sealed, the seal membrane is arched, the top of the arch extends towards the valve, the shocking burst pipe is arranged in the peripheral wall of the valve channel, a shocking burst pipe spray outlet is formed in the inner surface of the peripheral wall, and the included angle between the axial center line of the shocking burst pipe spray outlet and the axial center line of the valve channel, namely the spray angle of the shocking burst pipe ranges from 40 degrees to 50 degrees.
Description
Technical field
The present invention relates to valve technology, particularly a kind of electric detonation diaphragm valve, just can fully open valve by the shape of seal membrane and the position relationship of seal membrane and electric detonator angle of attack are set fast to guarantee that electric detonator detonates moment.
Background technique
Valve is normally used for controlling direction, the pressure of fluid, the device of flow in fluid system.Electric detonation diaphragm valve is different from common valve, and it is assemblied in the outlet of pressurized container conventionally, does not carry out modulability control, and just outlet is sealed.In the time needing pressurized gas in pressurized container spouting from outlet moment, just give electric detonator the electrical signal that detonates, electric detonator just can puncture rapidly the diaphragm originally sealing, and pressurized container is opened fast.So-called opening is fast most urgent sometimes, for example, need on-the-spot moment to eliminate initial burning things which may cause a fire disaster to eliminate fire or to fire the urgencies such as event, if open insufficient or open to have some setbacks or open and be obstructed etc., can affect adversely the opportune time.Inventor thinks, the position relationship of the shape of seal membrane and seal membrane and electric detonator angle of attack has significant impact to the valve open performance of electric detonation diaphragm valve.Through retrieval, do not have to find just can fully open fast the technology of valve by the shape of seal membrane and the position relationship of seal membrane and electric detonator angle of attack are set moment to guarantee that electric detonator detonates.
Summary of the invention
The present invention is directed to the defect or the deficiency that in prior art, exist, a kind of electric detonation diaphragm valve is provided, just can moment fully opens fast valve by the shape of seal membrane and the position relationship of seal membrane and electric detonator angle of attack are set to be conducive to guarantee that electric detonator detonates.
Technological scheme of the present invention is as follows:
Electric detonation diaphragm valve, it is characterized in that, comprise electric detonator, valve, seal membrane and valve seat, the periphery of described seal membrane is clamped between described valve and described valve seat to seal up the described valve passage forming of connecting with described valve seat, described seal membrane is arch, the vault of described arch extends to valve side, described electric detonator is arranged in the perisporium of valve passage, the internal surface of described perisporium has electric detonator jet exit, the angle of the longitudinal center line of described electric detonator jet exit and the longitudinal center line of described valve passage is that electric detonator angle of attack is 40 degree to 50 degree.
Described arch is that seal membrane sagitta is 4～8mm from the arch end to the size of vault.
Described valve passage bore is φ 30～45mm.
The periphery of described seal membrane sticks up to valve rollover, and the angle of tilt that forms seal membrane alice is the angle of the longitudinal center line of alice and described valve passage.
Described seal membrane alice angle of tilt is 30 degree to 33 degree.
The position that clamps described seal membrane alice between described valve and described valve seat is inclined-plane concave-convex fit structure.
The retaining part of described valve is inclined convex edge, and the retaining part of described valve seat is inclined-plane concave slope.
Described valve and described valve seat are fastenedly connected by hexagon socket head cap screw.
Technique effect of the present invention is as follows: electric detonation diaphragm valve of the present invention sprays seal membrane with the spray angle of 40 degree to 50 degree and can be conducive to guarantee that electric detonator detonates just can moment fully open fast valve by the arcuate in shape of seal membrane and electric detonator are set.Valve seat valve seal diaphragm all adopts 30 °～33 ° angles, seal membrane is put in 30 °～33 ° angles of valve seat, valve is put in 30 °～33 °, the inclined-plane angle above seal membrane and aligns, evenly firmly tighten with 4 hexagon socket head cap screws, utilize 30 °～33 ° inclined-planes that seal membrane is compressed, ensure the sealing in valve seat, electric detonator is fixed on valve with screw thread, with injection direction angle be that 40 °～50 ° seal membranes are positive arch, high 4～8mm, in the time giving electric detonator time break, electric detonator produces high-temperature high-pressure air flow and punctures seal membrane along pore direction, open gas cylinder passage, pressure of the inside of a bottle is ejected fast.The injection bore of valve valve seat is φ 30～φ 45.
