Embodiment Construction
[0017] The present invention adopts two two-position three-way electromagnetic ball valves with small flow rate as pilot control valves, and adopts the method of inserting and adding a cover plate to connect four sets of cone valve-type two-way inserting assemblies with the same structure through holes opened inside the valve body. , the pilot control valve controls the opening or closing of the valve ports of each cartridge assembly, thereby changing the communication mode of the four valve ports P, A, B, and T of the three-position four-way electromagnetic reversing valve to realize the reversing function. The specific implementation will be further described below in conjunction with the accompanying drawings:
[0018]The present invention consists of two pilot control valves (a, b), four sets of plug-in components (c, d, e, f), two control cover plates (1, 2) and one plug-in block (3), each The plug-in assembly includes a valve core (10), a valve sleeve (9), a spring (5) a...
