Abstract

The invention relates to a two-position three-way electromagnetic valve, in particular to a full-unloading disc type magnetic pole large-drift-diameter two-position three-way electromagnetic valve, which is used for solving the problems that when an existing two-position three-way electromagnetic valve is designed in a non-unloading large-drift-diameter mode, the opening and closing response is slow, the structural size and the weight are large, then the capacity of an air inlet channel and an air outlet channel is limited, and the response performance of a high-thrust engine of over 3000N is influenced. The full-unloading disc type magnetic pole large-drift-diameter two-position three-way electromagnetic valve comprises a valve body, an electromagnetic shell, an outer lining ring, an inner lining ring, an exhaust valve seat, an air inlet valve seat, a valve element rod, a reset spring, a magnetic disc and a coil.

Description

technical field [0001] The invention relates to a two-position three-way solenoid valve, in particular to a two-position three-way solenoid valve with a full unloading disc type magnetic maximum diameter. Background technique [0002] In the fast-response high-thrust orbital control engine, the system sometimes requires the control valve to meet the high-flow and high-pressure requirements of the high-thrust engine above 3000N, and at the same time, it should also achieve fast opening and closing response, light structure and valve flow resistance loss low performance. In order to meet the above scheme, an electro-pneumatic valve structure composed of a two-position three-way electromagnetic auxiliary valve and a two-position two-way air-controlled main valve is usually used. The control of inflation pressure build-up and exhaust pressure relief is realized by using the change of the air pressure in the control chamber to realize the opening and closing control of the main ...
