Embodiment Construction

[0033] The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention.

[0034] Below, first refer to figure 1 The structure of the solenoid valve 1 according to the embodiment of the present application will be described in detail.

[0035] Such as figure 1 As shown, the solenoid valve 1 may include a valve core 10 , an electromagnet 20 , a valve seat 30 and a sealing elastic member 40 . The valve core 10 , the electromagnet 20 , the valve seat 30 and the sealing elastic member 40 can all or partly be located in the housing 70 . In this embodiment, the electromagnet 20 and the valve seat 30 are located on opposite sides of the valve core 10 . The spool 10 is movable to be engaged with the valve seat 30 to close the solenoid valve 1 , and is movable to be separated from the valve seat 30 to be opened to the solenoid valve 1 . In particular, the valve core 10 can seal the valve port 32 of the valve seat 30 , t...

Abstract

Disclosed is an electromagnetic valve (1), comprising: a valve core (10), the valve core (10) comprising a moving iron (11) and a sealing member (12); an electromagnet (20), the electromagnet (20) being configured to make the valve core (10) move along a first direction (X); a valve port (32), the valve port (32) being able to be closed and opened by the sealing member (12); and a sealed elastic member (40), the sealed elastic member (40) being configured to bias the moving iron (11) towards the valve port (32), the sealing member (12) thus tending to close the valve port (32), wherein the sealing member (12) can move relative to the moving iron (11) along the first direction (X) and an opposite second direction (Y).

Description

technical field [0001] The invention relates to a solenoid valve. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] The solenoid valve is the basic equipment in the industrial control system. Its working principle is to control the position of the valve core by controlling the power on and off of the solenoid coil, so as to realize the flow control of the fluid flowing through the solenoid valve and other functions. [0004] In the existing solenoid valve, when the electromagnet is excited, it mainly needs to overcome the fluid force generated by the pressure difference between the fluids on both sides of the valve and the sealing force exerted by the sealing spring to improve the sealing reliability of the valve. Since the magnetic field force of the fixed iron of the electromagnet on the spool (that is, the moving iron) will rapidly decay as the ga...
