Detailed Description
See figure 1. The miniature energy-saving electromagnetic valve in the prior art comprises a body 1, a coil 2 and a movable iron core 3, wherein the coil 2 and the movable iron core 3 form a coil assembly. The neck of the movable iron core 3 is provided with a helical spring 9, the other end of the helical spring is abutted against the coil 2, and the movable iron core is driven to move forwards or backwards through the matching of the spring and the coil. The movable iron core is hollow, the sealing elements 35 are filled in the movable iron core, and the sealing elements 35 extend to the head end face and the tail end face of the movable iron core. A gap is reserved between the periphery of the movable iron core 3 and the inner wall of the coil 2, so that an air channel is formed.
A supporting seat 8 is arranged behind the movable iron core 3, the supporting seat 8 is hollow to form an air passage, and the air passage is also formed in a coil behind the supporting seat. When the movable iron core 3 retreats, the rear end of the movable iron core pushes against the supporting seat 8, and the sealing element seals an air passage on the supporting seat.
