Background
Referring to fig. 1, the existing three-way electromagnetic valve is mostly of a normally closed type, generally of a single coil structure, and has a normally closed connection port, a normally open connection port, a universal connection port and a pilot head; when the pressure is fed into the normally closed port, the spring force must be enhanced along with the increase of the pressure, but the spring force cannot bear the impact force of the pressure and the area ratio of the flow hole along with the continuous increase of the flow hole and the pressure. When the pressure is increased, the downward thrust of the movable iron core is increased continuously, and when the movable iron core needs to be electrified, the movable iron core needs to overcome the impact force of the pressure and the area ratio of the normally open port, and the electromagnetic valve cannot work.
Therefore, the existing three-way electromagnetic valve can only achieve small flow and small pressure, if the large flow is needed, the electromagnetic coil of the electromagnetic valve is very large, the spring force needs to be very strong, namely the impact force of the pressure to the area ratio needs to be borne, and the spring force needs to be overcome when the three-way electromagnetic valve is opened; therefore, it is necessary to design a three-way electromagnetic valve which can withstand high pressure medium and can be freely opened and closed under high pressure.
