High-pressure rapid inflation and deflation system

Abstract

The invention provides a high-pressure rapid inflation and deflation system. The high-pressure rapid inflation and deflation system comprises a tank body, the two ends of the tank body are provided with an inflation head and a deflation head respectively and sealed through O-shaped sealing rings, and the inflation head, the tank body and the deflation head are all made of high-strength steel. According to the high-pressure rapid inflation and deflation system, the functional requirements for storing inert gases such as nitrogen, carbon dioxide and argon and rapidly inflating and deflating are met, and the blank of a non-welding forming high-pressure gas cylinder structure design method is filled up; the tank body, the deflation head and the inflation head are made of high-strength steel materials and form a closed container together with a manual stop valve and an ejector rod, so that the light weight of the high-pressure rapid inflation and deflation system is realized on the premise of ensuring the safety; and the tank body is connected with the deflation head and the inflation head in a fastening mode through threads and then fastened through an upper fixing plate, a lower fixing plate and a threaded rod, and the performance requirements for air tightness, safety, reliability and accuracy are met in a spherical sealing and sealing ring sealing mode.

Description

technical field [0001] The invention relates to a high-pressure rapid inflation and deflation system. Background technique [0002] High-pressure rapid gas filling and deflation systems are widely used, but at present, domestic high-pressure gas storage tanks are mainly welded and formed structures, and the production, processing and molding of lightweight structural high-pressure containers are difficult, and there is no high-pressure gas storage tank with integrated rapid gas charging and deflation functions. At present, the material selection standards for high-pressure vessels in China are limited to low-strength materials, and the production technology of high-strength raw materials lags far behind Japan, Germany, the United States and other western developed countries, and the welding and forming technology of high-strength steel high-pressure vessels, domestic As a result, the design of high-pressure vessels can only ensure the strength by selecting low-strength mater...

Problems solved by technology

[0002] High-pressure quick filling and deflation systems are widely used, but at present, domestic high-pressure gas storage tanks are mainly welded structures, and the production, processing and molding of lightweight structural high-pressure containers are difficult, and there is no high-pressure gas storage tank with integrated fast filling and deflation functions.

At present, the material selection standards for high-pressure vessels in China are limited to low-strength materials, and the production technology of high-strength raw materials lags far behind Japan, Germany, the United States and other western developed countries, and the welding and forming technology of high-strength steel high-pressure vessels, domestic As a result, the design of high-pressure vessels can only ensure the strength by selecting low-strength materials to increase the wall thickness, and cannot achieve substantial weight reduction.
