Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to an electric flushing-free stop valve. Background Art

[0002] The electric flush-free globe valve is a special valve designed to prevent high-speed media erosion, ensuring long-term durability and reliability of the sealing surface. Through its unique design and operating principle, the electric flush-free globe valve effectively solves the sealing surface wear and leakage problems caused by media erosion during use of traditional globe valves.

[0003] The valve core (valve disc) of existing electric flushless stop valves is often fixedly connected to the valve stem. During long-term use, the valve core sealing surface may become damaged due to various reasons. Once the valve core is damaged, internal leakage will occur, which requires the entire valve body to be removed from the pipeline for repair or replacement. This not only reduces maintenance efficiency but also causes significant economic losses. Therefore, an electric flushless stop valve is proposed. Utility Model Content
