Abstract

The invention discloses a high-pressure gas filling valve, which comprises an inflatable seat body, a through hole, a valve cavity, an inflatable nozzle, an inflatable valve, a retaining ring and a first sealing ring. There is a through hole under the mouth, a valve cavity under the through hole, a retaining ring under the valve cavity, an inflation valve and a first sealing ring inside the valve cavity; one end of the inflation valve is an inflation thimble, and the other end is an inflation valve core ; The first sealing ring is set on the inflation thimble, and the inflation hole runs through from the top of the inflation thimble to the bottom and communicates with the valve chamber. A gas cracker includes an expansion tube and a gas-filled ignition head. The filling valve of the present invention has simple structure, easy processing of structural components, low manufacturing cost, and no air leakage; the gas cracker has simple structure, easy processing of structural components, low manufacturing cost, no air leakage, safe transportation, and no squibs Hidden danger, large expansion force.

Description

technical field [0001] The invention belongs to the technical field of gas filling valves, in particular to a high-pressure gas filling valve and a gas cracker thereof. Background technique [0002] In the prior art, the one-way valve is usually used for low-pressure inflation, and the high-pressure inflation usually adopts a screw-lock air-lock valve to lock and inflate, and the inflation speed is slow. There is also a high-pressure inflation valve imported from the United States, which has a complex structure, high manufacturing process requirements, and is expensive. Due to the high price, the application field is limited. [0003] If the cracking device needs to be cleaned during the filling process (multiple processes are required), it is necessary to manually screw the screw to lock the gas. Even if the one-way valve disclosed by the notification number CN205858345U is used to fill the liquid carbon dioxide, it needs to be filled to 10- With a pressure of 150MPa, the ...
