Abstract

The invention relates to a satellite-used bilateral shearing-type normally-closed titanium alloy gunpowder fuel gas actuated valve, which mainly comprises a matrix, a blind pipe component, a cutter, a burning resisting ring, a seal ring, a choke plug, a sealing fin, a plug and a soldering flake, wherein the cutter is arranged in an inner chamber of the matrix and is in matching seal with the matrix through a seal component; a high-pressure high-temperature fuel gas chamber, a cutter channel and a cuttings chamber are formed in the inner chamber of the matrix in sequence; and the blind pipe component is fixed on the matrix and runs through the matrix and the cutter channel. Conical surface wedge tightness seal is formed by the cutter and the matrix after the cutter acts, so that the seal reliability and resistance to pressure of the valve are improved after the valve acts, thereby being beneficial for long-term storage of a medium.

Description

technical field [0001] The invention relates to a double-sided cut-off type normally closed titanium alloy gunpowder gas actuated valve for satellites, which is used in different parts of satellite propulsion subsystems to control the opening of helium and propellants. Background technique [0002] The gunpowder gas actuated valve is one of the important automatic components in various systems of aerospace models, and plays a role in fluid control in the system. The gunpowder gas actuated valve is actuated by the high-pressure gas generated by the combustion of gunpowder. It has the characteristics of good sealing, small size, light weight, fast response, and it can actuate high-voltage energy with only a small pulse power supply. Therefore, Widely used in liquid rocket engines. At present, in various aerospace model systems in our country, the gunpowder gas actuated valve is mostly used in the workplace where the working medium is isolated and closed. However, the existin...
