The valve seat is provided with a valve core insertion hole, and a bottom of the valve core insertion hole is provided with a valve port. The valve cavity housing is detachably assembled with the valve seat. A valve core is guided and assembled in the valve cavity housing, the valve core has an inserted segment, the inserted segment is inserted in the valve core insertion hole, and the valve core is provided with a flow channel. An insertion sealing ring is provided between a hole wall of the valve core insertion hole and an outer peripheral surface of the inserted segment of the valve core. The valve seat and the valve cavity housing are relatively translated in an axial direction of the valve core insertion hole and are assembled in place in a relatively translational manner. A fixed structure is provided between the valve seat and the valve cavity housing, and the fixed structure is configured to relatively fix the valve seat and the valve cavity housing when the valve seat and the valve cavity housing are assemble…
