Abstract

A permanent magnetic valve with a characteristic of fast response is used for executive components of fuel-feeding control and high-accuracy control systems of an automobile and a rocket engine. By means of a permanent magnet, the characteristics of a magnetic circuit are changed, inductivity of a magnetic valve coil is reduced, and the magnetic valve can produces the fast response to a signal, achieves quick starting and closing and improves a pulse characteristic of an engine and stability of the systems. The permanent magnetic valve comprises a connector, a filter device assembly, the permanent magnet, a casing, the coil, a valve body, an upper gasket, an armature assembly, a lower gasket and a valve seat. The filter device assembly comprises an upper press ring, a filter screen and a lower press ring. The armature assembly comprises an armature, an upper reed, a lower reed, an outer fastening ring, a blocking plate, a pin, an inner fastening ring and a magnetic inducting ring. The valve adopts the permanent magnet to adjust the characteristics of the magnetic circuit, enables current on the coil to be changed fast and enables switching speed of the magnetic valve to be improved remarkably. Resultant force consisting of permanent magnetic force produced by the permanent magnet and spring force can ensure reliable seal of the valve seat.

Description

technical field [0001] The invention relates to a permanent magnet solenoid valve with fast response characteristics, which can be used for the management and control of engine fuel media with high requirements on impulse response characteristics, and can also be used as a key executive element of high stability control systems and hydraulic systems. Background technique [0002] Fast Response Switching Solenoid valves are the key actuators of many control systems, and the switching speed of solenoid valves is directly related to the stability and controllability of the system. [0003] In addition, the pulse characteristics of the engine are closely related to the response speed of the solenoid valve. For liquid rocket engines, automobile engines and other products that require very high pulse performance and consistency, it is a very critical technology to realize the rapid response of the solenoid valve. The faster the response speed of the solenoid valve, the better the...
