Described a kind of electrical ball valve, it is characterised in that: the wire diameter of described valve seat O is higher than groove end face on joint and on the end of valve body, line part junction between groove end face 0.2 to 3 millimeters.
Described a kind of electrical ball valve, it is characterised in that: on described joint, groove path is not more than valve seat O internal diameter, and on joint, the big footpath of groove is not less than valve seat O external diameter.
Described a kind of electrical ball valve, it is characterised in that: the right-hand member port of described valve end is set to the conical surface.
Described a kind of electrical ball valve, it is characterised in that: the port of described valve body side port is provided with groove, and the executor's sealing gasket between executor and valve body side port is arranged in a groove.
Described a kind of electrical ball valve, it is characterised in that: tighten with two bolts when sealing with executor's sealing gasket between described valve body side port and executor, thus the sealing realized between valve body and executor is with fixing.
Operation principle of the present utility model is to utilize the elastic compression of O to make seat compression spool, thus realizing the sealing of valve seat and valve core chamber, makes electrical ball valve switching torque less.
This utility model compared with prior art has the advantage that 1, switching torque is greatly lowered；2, cost and the volume of executor are greatly reduced；3, energy consumption when system is run is reduced.
