Description

High-pressure valve structure Technical Field The invention relates to the technical field of valve sealing, in particular to a high-pressure valve structure. Background The valve plays a key role in various fluid control systems, and can be completely opened or closed to allow or prevent fluid flow, and then the flow rate of the fluid is controlled by adjusting the opening of the valve, so that the variety and the specification are quite various, and the valve can be divided into a low-pressure valve, a high-pressure valve and the like according to the controlled pressure. Through retrieval, the high-pressure valve structure and the processing technology of the bulletin No. CN118328165A comprise a valve body, wherein the top of the valve body is fixedly connected with a top cover, the top of the top cover is fixedly connected with a bracket, the top of the bracket is provided with an actuator, the bottom of the actuator is provided with a valve rod, the bottom of the valve rod penetrates through the top cover and the valve body and is fixedly connected with a valve clack, an inner shell is arranged between the top cover and the valve body, and the valve clack is positioned in the inner shell and is in sliding connection with the inner shell. Based on the above patent, in the use process of the traditional stop valve, most of the valves are sealed by sealing gaskets or fillers in the use and sealing processes, so that the sealing method is single and the effect is limited; in order to solve the technical problem of single sealing method, the application provides a high-pressure valve structure. Disclosure of Invention The invention aims to solve the defects in the prior art, and provides a high-pressure valve structure, which can obviously improve the sealing effect of a valve, prolong the service life of the valve and ensure the safety of a system and the reliability of operation through two sealing modes of a valve clack and a sealing ring.
