Abstract

The invention provides a quick-response solenoid electromagnetic valve which is mainly composed of an inlet connector (1), an outer magnetizer (2), a return spring (3), a return spring gasket (4), a valve body (5), a coil (6), an armature assembly (7), a sealing spring gasket (8) and a valve seat (9). According to the quick-response solenoid electromagnetic valve, the return spring (3) is added, and idle running is arranged between the return spring (3) and the armature assembly (7), so that the return spring (3) can absorb kinetic energy generated in the start and movement processes of armature without influencing switching-on of the electromagnetic valve and convert the kinetic energy into elastic potential energy for accelerating switching-off of the electromagnetic valve, and thus the switching-on response time and the switching-off response time of the electromagnetic valve are increased simultaneously. Moreover, the armature assembly (7) is of a two-end-suspended friction-free structure, and the electromagnetic valve can have the advantage of being long in service life while the response time is furthermore increased.

Description

technical field

[0001] The invention belongs to the mechanical field and relates to a solenoid valve structure suitable for a satellite attitude control engine. Background technique

[0002] Solenoid solenoid valve has been widely used in aerospace, automobile and petrochemical fields due to its simple structure, reliable function and stable performance. The response speed of the solenoid solenoid valve is its key technical index. For example, the solenoid solenoid valve used for satellite attitude control thrusters, its response speed directly determines the maneuverability and flexibility of attitude adjustment, which is related to whether the satellite can quickly , Accurate orbit. Therefore, the response characteristics of solenoid valves have become the key performance pursued in the design of aerospace solenoid valves, and are also the main direction for the development of high-performance solenoid valves.
