The electromagnetic valve comprises an electromagnetic coil 2, a valve seat 3, a rectangular sealing ring 4, a valve core 5, a sliding valve core 6 and a reset spring 7, wherein the electromagnetic coil 2 and the valve seat 3 are welded to form a basic positioning structure, two ends of the reset spring 7 are simultaneously used for pushing the valve core 5 and the sliding valve core 6 to two ends in a reverse direction respectively to be pressed and fixed after being pre-pressed, a first sealing ring belt is formed at the G position of the valve seat 3, and the rectangular sealing ring 4 forms a static sealing second sealing point;
the sliding valve core 6 is provided with a flow channel C and a flow channel D, a sealing surface F is tightly matched with the valve seat 3 at the position G, and the flow channel B is blocked to be communicated with the flow channel E by virtue of a rectangular sealing ring 4;
the electromagnetic coil 2 comprises an electromagnetic coil shell 8, a copper coil 9 and a wrapping layer 1, wherein the copper coil 9 is tightly wrapped by the wrapping layer 1 and then is pressed into the electromagnetic coil shell 8 together, and the position K at the center serves as an electromagnetic pure iron structure;

the valve seat 3 is internally provided with a rectangular sealing ring groove, and the rectangular sealing ring 4 is positioned in the rectangular sealing ring groove. The axial sealing function can be achieved in the process that the sliding valve core 6 moves upwards after the electromagnetic coil 2 is electrified.
Principle of operation
The working state can be divided into two states of power-on and power-off; its function is to adjust the direction, flow, speed and other parameters of the medium in the system.
As shown in fig. 2, the non-energized operating state is the same as the assembled state; the valve core 5 and the slide valve core 6 are kept static under the action of the reset spring 7, a flow channel D on the slide valve core 6 is unblocked, and a channel through which a medium can flow is formed through A, C, E;
as shown in fig. 3, when the electromagnetic coil 2 of the switching valve is powered on, the electromagnetic coil 2 generates electromagnetic force, the sliding valve core 6 starts to move upwards under the action of the electromagnetic force to overcome the pre-pressure of the reset spring 7, at this time, the valve port G is opened until the valve core 5 contacts with the sliding valve core 6 to finally form another sealing ring band H, so that the valve port D is closed, and finally, the rectangular sealing ring 4 replaces the sealing function of the valve port G to block the communication between the flow passage a and the flow passage E, so that the flow passage B and the flow passage E are communicated, and the initial state is restored after the power failure;
then under the system requirement, the two working states are quickly and mutually converted to form a high-speed switch valve with a two-position three-way structure.
