AI Technical Summary
Technical Problem
Existing shut-off valves cannot effectively intercept impurities in the fluid, leading to blockage or damage, and their sealing performance is weak, resulting in fluid leakage and affecting the reliable operation of the equipment.
Method used
By precisely controlling the upper and lower rotating plates and ensuring a tight fit between the sealing gasket and sealing ring, the fluid channel can be flexibly opened and closed. Impurities are intercepted by the packing material inside the filter box, enhancing the sealing performance and facilitating filter box maintenance.
Benefits of technology
It achieves efficient filtration and sealing of fluids, prevents leakage, extends the service life of shut-off valves, and ensures fluid purity and reliable equipment operation.
