The sleeve 2 is embedded in the mounting cavity 14, the upper end of the sleeve 2 is communicated with the outer side of the valve body 1, and the lower end of the sleeve 2 is communicated with the flow passage 11. The upper end of the sleeve 2 is embedded with a static iron core 21, and the sleeve 2 is internally provided with a movable iron core 22 in a sliding way. The upper end surface of the movable iron core 22 is provided with a first annular groove 221, and the lower end surface of the static iron core 21 is provided with a second annular groove 211. A return spring 4 is arranged in the sleeve 2, the upper end of the return spring 4 is embedded in the first annular groove 221, and the lower end of the return spring 4 is embedded in the second annular groove 211.

A sealing member 222 is fixedly arranged at the lower end of the movable iron core 22, and in the present embodiment, the sealing member 222 is made of rubber. A sealing groove 15 is formed in the valve body 1, the sealing groove 15 and the sleeve 2 are coaxially arranged, and the upper end of the sealing groove 15 is communicated with the flow channel 11. When the valve is closed, the sealing element 222 penetrates through the flow passage 11 and is embedded in the sealing groove 15, so that the situation that the medium in the flow passage 11 impacts the sealing element 222 to cause the sealing element 222 to vibrate can be reduced.

The static iron core 21 is coaxially provided with a sliding groove 212 in a penetrating manner, the upper end of the movable iron core 22 is coaxially welded with a control lever 5, and the control lever 5 penetrates through the sliding groove 212 and extends to the outer side of the valve body 1. The handle 51 is welded to the upper end of the operating rod. When the electromagnetic coil 3 or other electronic components are in failure, the grippable handle 51 pulls the operating rod 5 upwards, so that the sealing member 222 slides into the sleeve 2, i.e. the opening of the electromagnetic valve is realized. Thus, the emergency opening of the solenoid valve can be realized.

In order to facilitate the fixing of the operating rod 5 after the solenoid valve is manually opened, the valve body 1 is provided with a fixing component for fixing the operating rod 5.
