Abstract

An energy-saving type automatic compensation valve core multi-functional pilot solenoid valve comprises a valve body and a solenoid drive mechanism, a wave-shaped diaphragm is arranged inside a valve chamber and comprises a main diaphragm, wave-shaped lips are arranged in a radial extension manner on the periphery of the main diaphragm, auxiliary flow passages are arranged in a valve cover and the valve body and internally provided with an auxiliary valve, the auxiliary valve comprises an auxiliary valve core, the auxiliary valve core is connected with a dynamic magnetic core in the solenoid drive mechanism, and an adjusting screw is arranged inside the valve cover and extends into the auxiliary flow passage. The energy-saving type automatic compensation valve core multi-functional pilot solenoid valve is suitable for large-stroke and mass-flow occasions, strong in shock resistance, reliable in sealing, capable of compensating errors during actual processing and assembling and controlling on-off speed of the valve according to actual requirements, and strong in applicable medium load performance, the valve is maintained open in an electrically neutral manner, and the electricity power is saved.

Description

Technical field: [0001] The invention relates to the mechanical field, in particular to a valve, in particular to an energy-saving multifunctional pilot solenoid valve with automatic compensating valve core. Background technique: [0002] In the prior art, the diaphragm solenoid valve has been widely used because of its convenient processing, film molding, simple structure, low cost, less maintenance, and less strict requirements on the cleanliness of the medium. The diaphragm solenoid valve is closed by the interaction of the spring and the main spool (diaphragm), while the auxiliary spool adopts a direct-acting soft seal. The flat diaphragm has a small stroke and a small flow rate, which is not suitable for the working requirements of a large stroke and a large flow rate; the valve core will be within the processing tolerance range of the parts, and the closing performance will decrease or the valve cannot be closed normally, and the service life will be reduced; in additi...
