Corrosion-resistant valve seal structure

Abstract

This utility model belongs to the field of valves, specifically a corrosion-resistant valve sealing structure. It addresses the shortcomings of existing valve sealing performance: traditional valve sealing structures are prone to leakage after long-term use, affecting production safety. Installation and maintenance are also complex, requiring professional personnel and increasing maintenance costs and time. The proposed solution includes a main valve body and two auxiliary valve bodies, located at opposite ends of the main valve body. The auxiliary valve bodies and the main valve body are fixedly connected by a connecting assembly. A valve stem rotatably passes through the top center of the main valve body, and a valve plate is fixedly connected to the bottom of the valve stem. In this utility model, multiple sliding arc-shaped plates form a ring-shaped sealing structure, combined with the compression sealing of side rubber strips, ensuring zero leakage when the valve is closed. Simultaneously, the sealing ring between the limiting ring and the fixing ring further enhances the sealing performance, effectively preventing media leakage.
