一种二位三通双向截止的插装式高压型电磁球阀
By designing a two-position three-way bidirectional shut-off cartridge-type high-pressure solenoid ball valve, and combining the valve body, electromagnetic drive assembly, and ball valve assembly, the internal leakage and sealing reliability problems of traditional hydraulic solenoid valves under high-pressure conditions are solved. This achieves zero-leakage line sealing and bidirectional shut-off and switching control with multiple ports, improving the valve's sealing performance and stability.

AI Technical Summary
Traditional hydraulic solenoid valves suffer from internal leakage and poor sealing reliability under high-pressure conditions, and cannot achieve a three-position bidirectional shut-off function with a single valve body.
The cartridge-type high-pressure solenoid ball valve with two-position three-way bidirectional shut-off is combined with the valve body, electromagnetic drive assembly and ball valve assembly. It utilizes the symmetrical hemispherical sealing surface and conical valve seat to cooperate with the valve core and pressure balance chamber, and sets up a stepped valve core and pressure balance chamber to achieve zero leakage line sealing and bidirectional shut-off and switching control of multiple oil ports.
It achieves zero-leakage line sealing under high-pressure conditions, improves valve sealing and stability, extends service life, and supports efficient switching control of multiple oil ports.
