Abstract

The invention discloses a high-temperature fuel gas adjusting valve used for a rocket engine. The high-temperature fuel gas adjusting valve used for the rocket engine is composed of a valve body, an upper end cover, connection end covers, a motor shaft sleeve, a rotating shaft, a valve element and a valve element bracket. The motor is fixedly connected with the upper end cover; an output shaft of the motor is fixedly connected with the motor shaft sleeve which is connected with the rotating shaft and the valve element in a cooperative manner, and positioning and transmission are achieved; and the valve element is connected with the valve element bracket. Gas conveying pipe heat insulating pieces are installed at the two ends of the valve element bracket and fixedly connected with the connection end covers; the valve body is in threaded connection with the connection end covers and is fixedly connected with the upper end cover through bolts; and the connection end covers are connected with a fuel gas pipeline. The high-temperature fuel gas adjusting valve changes the circulating area by changing the rotating angle of the valve, and therefore thrust adjustment of a solid propellant engine, flow adjustment of a solid fuel gas generator or fuel gas flow adjustment of a primary fuel gas generator of the solid rocket ramjet engine can be achieved; and the high-temperature fuel gas adjusting valve is safe and reliable. The high-temperature fuel gas adjusting valve is simple in structure, convenient to install and operate and good in heat protection effect.

Description

technical field [0001] The invention relates to the technology of thrust regulation of solid rocket motor and flow regulation of solid rocket motor, in particular, relates to a high-temperature gas regulating valve for rocket motor. Background technique [0002] In the variable thrust technology of solid engines and the gas flow regulation technology of solid rocket ramjet engines, the gas control valve design scheme is a good scheme, and many schemes have been tested and verified. [0003] Among the existing published technical documents, invention patent 201310345207.8 discloses an electric cone valve type solid rocket ramjet gas flow regulating device, and patent 201310380537.0 proposes a cone valve type gas flow regulating device. The main difference between these two regulating device patents is the driving device of the valve, and the main body of the regulating device is a cone valve. When the cone valve is used for flow adjustment, the requirements for the profile o...
