Background

The two-position three-way electromagnetic valve can provide control gas for the gas actuating valve and provide an exhaust passage of the control gas. The traditional two-position three-way electromagnetic valve generally has two types of structures, namely a split type structure and an integral type structure: (1) the split type two-position three-way electromagnetic valve generally comprises an upper valve and a lower valve, the valves are linked with an iron core through ejector rods, the parts sealed with the valves are integrated on a shell, the processing difficulty is high, and the structure is complex. (2) The integral two-position three-way electromagnetic valve integrates the iron core and the valve, realizes the functions of power-on suction and sealing and simplifies the product structure. However, in the arrangement of the flow channel, the inlet gas generally passes through the flow channel of the electromagnet part and then enters the outlet through the flow channel on the shell, and the connection between the two channels has a problem of unsmoothness. Aiming at the technical defects of the traditional integral two-position three-way electromagnetic valve.
