Abstract

The invention provides an anti-vibration one-way valve for a corrugated spring. The anti-vibration one-way valve comprises an inlet connecting pipe nozzle, an outlet connecting pipe nozzle and an elevating pipe. A first concave cavity is formed in the right end face of the inlet connecting pipe nozzle. A first conical face cavity is formed in the left end face of the inlet connecting pipe nozzle.The first concave cavity and the first conical face cavity communicate through a first through cavity, and the first concave cavity, the first conical face cavity and the first through cavity are coaxial. A second concave cavity is formed in the left end face of the outlet connecting pipe nozzle. A second conical face cavity is formed in the right end face of the outlet connecting pipe nozzle. Thesecond concave cavity and the second conical face cavity communicate through a second through cavity, and the second concave cavity, the second conical face cavity and the second through cavity are coaxial. When the inlet connecting pipe nozzle and the outlet connecting pipe nozzle are in left and right butt joint, the right end face of the inlet connecting pipe nozzle and the left end face of the outlet connecting pipe nozzle are attached closely, and the first concave cavity and the second concave cavity form a space for containing an elevating valve. The opening and closing pressure difference of the one-way valve is reduced remarkably, and the vibration time is short.

Description

technical field [0001] The invention relates to a corrugated spring anti-vibration one-way valve, which is suitable for a booster conveying system of a launch vehicle and belongs to the field of valves. Background technique [0002] The one-way valve is an important part of the gas pressurization system of the launch vehicle, and it is widely used in the gas circuit of pressurization, ejection, and gas seal. In the prior art, the non-return valve has repeatedly fluttered in stand-alone tests and shooting range tests, affecting the normal operation of the booster system, and in severe cases, it may also cause the failure of the valve itself or the structure of other components of the booster system destroy. Contents of the invention [0003] (1) Technical problems to be solved [0004] Based on the above-mentioned deficiencies in the prior art, the present invention proposes a corrugated spring anti-vibration one-way valve, the opening and closing pressure difference of t...
