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 ...
