Abstract

The invention discloses an integrated decompression device, comprising: a first high-pressure self-locking valve, a second high-pressure self-locking valve, a third high-pressure self-locking valve, a decompression valve I, a decompression valve II, a decompression valve III, One-way valve I, one-way valve II, inlet multi-way element I, inlet multi-way element II, outlet multi-way element, outlet three-way element, conduit, bottom plate, second outer casing nut II, first band I, second Cuff I, third cuff I, cuff II, first cuff III, second cuff III, cuff IV, first pressure sensor I, second pressure sensor I, pressure sensor II and pressure sensor III. The present invention integrates components used for decompression in each path, realizes the decompression of two paths of high-pressure gas to the required pressure of each path and divides the flow to realize the supply of four paths of gas, so that the device has high functional integration, small weight, The advantages of more convenient use and maintenance.

Description

technical field [0001] The invention belongs to the technical field of gas medium delivery in aerospace propulsion systems, and in particular relates to an integrated decompression device. Background technique [0002] In the spacecraft propulsion system, the gas medium is mainly used for the pressurization of the propellant tank, the actuation control of the air control valve of the engine, the whirling and blowing of the engine starting turbine, etc. The above three types of uses have different requirements on the pressure of the gas medium, so three Air supply with different pressures. The gas medium is generally stored in the container at high pressure. Except for the engine starting turbine whirling blowing path, the gas pressure required by the other two paths is relatively low. Therefore, it is necessary to decompress the gas medium stored in the high-pressure container to meet the requirements. Two-way pressure demand for supply gas. [0003] The existing decompres...
