Description
Technical field
The present invention relates to gas cylinder technology woods stock, in particular it relates to one disclosure satisfy that high pressure high-cleanness, high requirement
Under the gas cylinder with deflation structure of supply demand and bleed method.
Background technology
Filling gas pressure vessel has been widely used for the every field of productive life, and major part pressure vessel is
Metal or metal are made with composite, and pressure is low, volume is big, weight is high, along with commercial production small size, gently
The requirement quantified, the requirement of gas cylinder improves the most therewith, and at present major part gas cylinder cannot meet this requirement, therefore,
High pressure, small size pressure vessel become the important directions of development.Especially limited in installation site, construction weight
Require strict, in the case of using environment harsh, be badly in need of small size high pressure or the ultrahigh pressure vessel of Development of Novel.
National inventing patent CN101463942A discloses a kind of minitype high voltage gas container inflation/deflation structure, this height
Pressure vessel is open annular structure, and gas cylinder air inlet is provided with charge valve, and outlet is provided with electric initiator, gas outlet
Connect unidirectional three-way valve.The electric initiator installed at cylinder outlet in this structure severs exit spool, discharges gas.
There are two kinds of risks in this structure, one be electric initiator be first use, if spool cannot once cut off, a whole set of
Device will lose efficacy, it is impossible to supply；Two be turned off during have metal structure to destroy, unavoidably produce metal dust,
Or gunpowder leakage in electric initiator once occurs, these fifth wheels can enter down-stream system, shadow with gases at high pressure
Ring GAS QUALITY；Three are destroyed spool and electric initiator is ramed and may affect gas and circulate.
National inventing patent CN202419129U discloses a kind of pressure vessel containing gases at high pressure, and gas outlet sets
Having the spool that can be destroyed, outside transfer block is provided with for destroying raming of spool, rams and is started by electric initiator.
During work, spool is destroyed, gas release in gas cylinder.There is the defect of four aspects in this structure: one is that gas cylinder work needs
Rely on having ramed of installing in outside transfer block, need transfer block to coordinate with gas cylinder accurately, otherwise can affect and hit
The power of spool is hit in butt, affects spool appearance of fracture, thus affects circulation area；Two is that transfer block needs to take one
Determine volume, cannot install and use in the case of some limited space；If three is to produce metal fragment after spool destroys,
Down-stream system can be entered, it is difficult to ensure GAS QUALITY with gases at high pressure；Four are destroyed spool and electric initiator hits
Head may affect gas circulation.
Therefore, existing gas cylinder and bleed method thereof cannot ensure that gases at high pressure discharge smoothly, and cannot meet
The requirement of high-cleanness, high.Meanwhile, there is certain difficulty in use in the structure of some limited space.
Summary of the invention
For above-mentioned deficiency present in prior art, object of the present invention is to provide one and there is deflation structure
Gas cylinder and bleed method, by electric initiator cut off cylinder outlet cut-out structure, get through gas cylinder venting
Passage, cuts off and has the angular groove of band in structure, have stress to concentrate at sharp corner during cut-out, and fracture is the most variable
Shape, cutting-off process is reliable, solves the shortcoming that existing structure cuts off poor reliability and break top broken affects circulation area；
By arranging multi-layer sintering filter screen at cylinder outlet, filter discharging gas in gas cylinder, solve in gas
Fifth wheel that may be present is brought into the hidden danger of down-stream system；Gas has the interface connecting electric initiator, protects
Demonstrate,prove electric initiator and the relative position cut off between structure, improve cut-out reliability, solved what switching brought
Coordinate deviation；After electric initiator work, the parts that drop are blocked is cutting off intracavity, will not block gas and pass through, and
The external part of raming of electric initiator is provided with groove at gas by part, it is ensured that the smooth circulation of gas, solves
After existing spool destroys, drop spool and electric initiator is ramed the hidden danger of blocking gas channel.
For achieving the above object, the present invention is achieved by the following technical solutions.
