an isolation sealing element 11 is arranged between the empty cavity 18 and the sealing cavity 7, and grooves 20 for arranging the isolation sealing element 11 are arranged at the top of the main valve body 1 and the bottom of the upper valve cover 3; the end B of the support rod 13 is sleeved in the isolation sealing piece 11 and extends into the sealing cavity 7, the valve port sealing piece 10 is fixed at the end B of the support rod 13, when the electromagnetic valve body 15 is powered off, the iron core 16 is ejected out through the spring 17 so as to drive the support rod 13 to swing, the valve port sealing piece 10 fixed at the end B of the support rod 13 seals the valve port 9, and the electromagnetic valve is in a closed state; when the electromagnetic valve body 15 is electrified, the iron core 16 is retracted to drive the supporting rod 13 to swing, so that the valve port sealing piece 10 fixed at the end B of the supporting rod 13 opens the valve port 9, and the electromagnetic valve is in an open state.
The middle position of the isolation sealing piece 11 is provided with an arc-shaped isolation surface 19, particularly, the arc-shaped isolation surface 19 is in a fold or wave shape, the supporting rod 13 is inserted from the arc-shaped isolation surface 19, so that the supporting rod 13 can swing flexibly, the middle of the arc-shaped isolation surface 19 is a wrapping sleeve extending into the sealing cavity 7, the end B of the supporting rod 13 is firmly wrapped by the wrapping sleeve and extends into the sealing cavity 7, and in particular implementation, the end B of the supporting rod 13 is used as an insert to be formed into the isolation sealing piece 11 at one time, further, the isolation sealing piece 11 is made of polytetrafluoroethylene, the isolation sealing piece 11 is formed by injection molding, when fluid enters the electromagnetic valve, no matter the electromagnetic valve is in an open state or a closed state, the fluid does not enter the end of the upper valve cover 3, namely, the fluid and the electromagnetic driving device 5 are completely isolated, and the influence of the fluid on the electromagnetic driving device 5 can be well reduced, for example, under the condition that no isolation, the fluid has granular impurities, the fluid can cause the iron core to be blocked; the acidic fluid may corrode the core, etc.
