Problems solved by technology
In order to improve the sealing performance of the gate plate of the valve, a sealing ring is usually arranged around the gate plate. Usually, the sealing ring and the gate plate are connected by adhesive or sleeved, which causes the sealing ring to be easily damaged after long-term use. Peeling or loosening, thus affecting the sealing of the gate and affecting the sealing of the valve

The invention relates to the technical field of valves, in particular to a valve gate sealing structure. The valve gate sealing structure comprises a gate, wherein a connecting rod mounting groove is formed in the top of the gate, a circle of internal thread is arranged in the mounting groove, a connecting rod fastening seat is arranged on the edge of the mounting groove, flexible sealing layer fixing grooves are formed in the front face and the back face of the gate respectively, and flexible sealing layers and the fixing grooves are fixed through pressing strips. According to the valve gate sealing structure, the connecting rod mounting groove is formed in the top of the gate, one circle of internal thread is arranged in the mounting groove, the connecting rod fastening seat is arranged on the edge of the mounting groove, the flexible sealing layer fixing grooves are formed in the front face and the back face of the gate respectively, and the flexible sealing layers and the fixing grooves are fixed through the pressing strips. By adopting the structure, the strength of connection between the flexible sealing layers and the gate is high, the compactness of connection is high, and the sealing performance of the gate is not affected by expansion damage after long-term soaking.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a valve gate sealing structure. Background technique [0002] Valve (Valve) is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of the flowing fluid medium. Valves are the basic components in the piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. In order to improve the sealing performance of the gate plate of the valve, a sealing ring is usually arranged around the gate plate. Usually, the sealing ring and the gate plate are connected by adhesive or sleeved, which causes the sealing ring to be easily damaged after long-term use. Peeling or loosening will affect the sealing performance of the gate and affect the sealing performance of the valve. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a ...
