Description

Technical Field

[0001] The utility model relates to the technical field of valve sleeves, in particular to a valve sleeve with a noise reduction function. Background Art

[0002] As one of the important parts of the valve, the valve stem is mainly used for transmission. The upper end of the valve stem is connected to the actuator or handle, and the lower end directly drives the valve core to move or rotate to achieve the valve opening or closing or regulation. During the installation and use of the valve, a protective cover is usually reinforced on the outside of the valve stem to ensure the normal opening and closing of the valve.
