Description
Technical field
The present invention relates to gas cylinder technology woods stock, particularly, relate to a kind of gas cylinder with deflation structure and bleed method thereof of the air feed demand that can meet under the requirement of high pressure high-cleanness, high.
Background technique
Filling gas pressurized container has been widely used in the every field of productive life, major part pressurized container is that metal or metal and composite material are made, pressure is low, volume is large, weight is high, along with industrial production small volume, light-weighted requirement, the requirement of gas cylinder also improves thereupon, current most of gas cylinder cannot meet this requirement, and therefore, high pressure, small volume pressurized container become the important directions of development.Especially limited in mounting point, structure weight requires strict, when Environmental Conditions is harsh, is 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, and this high-pressure bottle is open annular structure, and gas cylinder suction port is provided with gas charging valve, and outlet is provided with electric initiator, and air outlet connects unidirectional three-way valve.The electric initiator installed at cylinder outlet in this structure severs outlet port spool, release gas.There are two kinds of risks in this structure, one be electric initiator is once use, if spool cannot once cut off, package unit will lose efficacy, cannot air feed; Two is have Structural Hardware to destroy in cutting-off process, unavoidably produces metallic dust, or once occur that in electric initiator, gunpowder leaks, these fifth wheels can enter down-stream system with pressurized gas, affect GAS QUALITY; Three be destroyed spool and electric initiator ram may affect gas circulation.
National inventing patent CN202419129U discloses a kind of pressurized container of splendid attire pressurized gas, and air outlet is provided with the spool that can be destroyed, and outside transfer block is provided with for destroying raming of spool, rams to be started by electric initiator.During work, spool is destroyed, air release in gas cylinder.There is the defect of four aspects in this structure: one is that gas cylinder need of work relies on having ramed that outside transfer block is installed, and needs transfer block to coordinate accurately with gas cylinder, otherwise can affect to ram and clash into the power of spool, affects spool appearance of fracture, thus affect circulation area; Two is that transfer block needs to take certain volume, cannot install and use when some limited space; If three is produce metal fragment after spool destroys, down-stream system can be entered with pressurized gas, be difficult to ensure GAS QUALITY; Four be destroyed spool and electric initiator ram may affect gas circulation.
Therefore, existing gas cylinder and bleed method thereof cannot ensure that pressurized gas 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.
