Problems solved by technology

[0002] Globe valve is a valve that completely connects or cuts off the closed pipeline. It is widely used in industrial and living fields to control the flow of medium in pipelines. Usually, the globe valve rotates the handwheel to make the valve stem rise and fall to drive the valve disc to move vertically. The linear displacement of the medium flow direction achieves the purpose of opening and closing. At present, the inner sealing surface of the globe valve and the valve disc at the bottom of the valve stem are closed by the rotation of the hand wheel, which requires artificially providing sufficient tightening force to seal the valve disc and the valve body. The surface is compacted and fitted. When turning the handwheel to control the stop valve, it is often time-consuming and laborious, and it is difficult to completely disconnect the medium in the pipeline, which brings inconvenience to the user.

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0012] Such as figure 1 As shown, the present invention provides a rotary control shut-off valve, which includes a valve body 1, a valve stem 2, an air inlet joint 3 and an air outlet joint 4. Extending into the valve body 1, a sealing seat 6 is provided. The sealing seat 6 is arranged vertically upward. The upper surface of the sealing seat 6 is provided with a stepped groove, and the lower end surface of the valve flap 5 is provided with a Engaged protrusion 7; considering that the user can relieve the hand pressure when rotating the handwheel 8, the top of the valve stem 2 is provided with a handwheel 8 with a sheath 9, and the sheath 9 is a plastic material sleeve Connected to the edge of the hand wheel 8; as a preferred solution, considering that the valve disc 5 can be fully pressed against the sealing seat 6 during the downward mo...
