Description

Technical Field

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

[0002] As we all know, the rotor valve is a valve used to control the flow of fluids. Its core component is a rotating rotor, which is usually installed inside the valve. The rotor can be cylindrical, spherical or other shapes. By rotating to open or close the valve, the fluid can be turned on and off and the flow rate can be adjusted. Rotor valves are widely used in various industrial fields, including chemical, petroleum, natural gas, water treatment, etc. Its characteristics include simple structure, good sealing performance, wide adjustment range, etc., and are often used in occasions where frequent flow adjustment is required.
