Abstract

The invention relates to the technical field of aerospace, in particular to a valve combination device with an electric explosion valve in front. The valve combination device with the electric explosion valve in front comprises a shell body, an electric explosion valve control assembly, a one-way pressure increasing valve, a pressure reducer command valve and a pressure reducer main valve, a gas outlet port of the one-way pressure increasing valve communicates with a gas inlet port of a gas bottle, the gas bottle is connected to a gas inlet port of the pressure reducer main valve through a filler neck, the electric explosion valve control assembly is arranged on the filler neck, an air inlet port of the pressure reducer main valve communicates with the gas bottle, an outlet hole is formed in the pressure reducer main valve, the outlet hole communicates with an air inlet port of the pressure reducer command valve through a second channel, and an air outlet port of the pressure reducer command valve communicates with the pressure reducer main valve through a third channel. Communicating is carried out on a portion between the pressure reducer command valve and the pressure reducer main valve through a first pipeline, a second pipeline and a third pipeline, and therefore use of high-pressure pipelines is reduced, weld joints among the pipelines are reduced, and the reliability of the valve combination device with the electric explosion valve in front is improved.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a valve combination device with an electric explosion valve in front. Background technique [0002] Existing rocket engine extrusion conveying systems often use a decompression control unit to control the pressure of the air pillow in the storage tank, wherein the decompression control unit includes a gas cylinder connector, a booster one-way booster valve, a decompression valve, and a remote release of the gas cylinder. Pressure valves, filters, pressure sensors, tank pressure relief hand valves, safety valves and pipelines used to connect the above components. [0003] Among them, the parts and pipelines in the decompression control unit are connected by welding. However, under high pressure and vibration environment, cracks will appear between the parts and the pipeline, which will eventually cause the decompression control unit to lose its function.
