The invention discloses a high-temperature solenoid valve and a high-temperature thruster using the same. A thermal insulation pipe is sleeved on the periphery of the part of a valve rod of the high-temperature solenoid valve extending from the lower portion of a solenoid valve casing, during usage, media can diffuse a large amount of heat when passing through inlets and outlets on a valve seat, while heat generated by high-temperature gas needs to be transmitted to an electromagnetism through the thermal insulation pipe and the valve base in a transmission, convection and radiation mode, and the thermal insulation pipe fixed between the electromagnetism and the valve base and the valve rod penetrating through the thermal insulation pipe are made of thermal insulation materials, so that the thermal bridge effect can be achieved, heat exchanging between the valve base and the electromagnetism is reduced, heat diffused to the electromagnetism from the valve base is reduced, temperature of an electromagnetic coil is reduced during usage, the possibility of fusion of an insulation skin of the electromagnetic coil during usage is reduced, and the reliability of the solenoid valve used in the high-temperature environment is improved.
Description
technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a high-temperature solenoid valve, and also to a high-temperature thruster using the high-temperature solenoid valve. Background technique [0002] The spacecraft thruster is an important part of the spacecraft operation. According to the different fuel of the spacecraft, the requirements for the control components of the thruster are different. At present, solenoid valves are commonly used to control the work of high-temperature thrusters, so as to achieve the effect of adjusting the thrust of high-temperature thrusters from time to time. However, because the existing solenoid valve generally adopts that the electromagnet is directly fixed on the valve seat, for example, a direct-acting solenoid valve disclosed in a Chinese invention patent with the application number of 98217832.8, the valve seat in this type of solenoid valve is provided with a communicating The inlet...
