Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a globe valve. Background Art

[0002] The globe valve is one of the most widely used valves. It is widely popular because of the small friction between the sealing surfaces during the opening and closing process, relatively durable, small opening height, easy to manufacture, convenient to repair, and applicable not only to medium and low pressures but also to high pressures. As an extremely important cut-off valve, its sealing is achieved by applying torque to the valve stem. The valve stem applies pressure to the valve flap in the axial direction, making the sealing surface of the valve flap closely fit with the sealing surface of the valve seat to prevent the medium from leaking along the gap between the sealing surfaces.
