Embodiment Construction
[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] Specific embodiment 1 of the thruster assembly of the present invention, such as Figure 1 to Figure 4 As shown, the thruster assembly includes a high pressure air source pressure reducing valve 1 and a thruster 11, a pressure regulating pressure reducing valve 4 is provided between the high pressure gas source pressure reducing valve 1 and the thruster 11, and the pressure regulating pressure reducing valve 4 includes a valve body 40 and the valve seat 42 arranged in the valve body 40. The valve body 40 has a high-pressure chamber 48 on both sides of the valve seat 42 for high-pressure gas to enter and a low-pressure chamber for low-pressure gas to enter. The valve seat 42 is provided with The orifice 41 that communicates with the high-pressure chamber 48 and the low-pressure chamber and the spool 45 that adjusts the opening of the orifice through ...

The invention relates to a pressure regulating pressure reducing valve, a thruster assembly and an engine. The pressure regulating pressure reducing valve comprises a valve body and a valve seat arranged in the valve body, the valve body is internally provided with a high-pressure chamber for allowing a high-pressure fluid to enter and a low-pressure chamber for allowing a low-pressure fluid to enter, the high-pressure chamber and the low-pressure chamber are positioned on the two sides of the valve seat, a throttling opening communicating with the high-pressure chamber and the low-pressure chamber and a valve core used for adjusting the opening degree of the throttling opening through movement are arranged on the valve seat, a spring used for exerting elasticity on the valve core to enable the valve core to move in the direction enabling the opening degree of the throttling opening to be reduced is arranged in the high-pressure chamber, a piston which divides the low-pressure chamberinto an adjusting part and an output part is slidably assembled in the low-pressure chamber, the adjusting part is provided with an adjusting part inlet for allowing a low-pressure adjusting fluid toenter, the piston is provided with a pushing part which pushes the valve core to enable the valve core to open the throttling opening under the action of the pressure of the low-pressure adjusting fluid, and the adjusting part is provided with a low-pressure adjusting part outlet used for discharging the low-pressure adjusting fluid to enable the valve core to reduce the opening degree of the throttling opening.
Description
technical field [0001] The invention relates to a pressure regulating decompression valve, a thruster assembly and an engine. Background technique [0002] At present, the launched sounding rocket is equipped with an arrow platform with attitude control capability, which realizes the control of the arrow attitude. The attitude control engine it carries is a fixed-thrust engine, which cannot adjust the thrust of the engine according to the timing of the arrow attitude. Therefore, the control accuracy is poor. For the arrow platform, the normal Work has an impact. [0003] The application publication number is CN101907039A, and the Chinese patent application with the application publication date of 2010.12.08 discloses a nitrogen-cooled gas micro-propulsion device using three cylindrical propellant tanks. The nitrogen-cooled gas micro-propulsion device with three cylindrical propellant tanks includes three High-pressure propellant storage tank, high-pressure inflation valve,...
