Description

Valve structure suitable for high temperature high pressure operating mode Technical Field The utility model belongs to the technical field of valves, and relates to a valve structure suitable for high-temperature high-pressure working conditions. Background The valve is widely applied to the fields of petroleum and natural gas, petrochemical industry, environmental protection, electric power, metallurgy and the like, wherein the valve is not lack of the use scene of high temperature and high pressure. In a high-temperature and high-pressure scene, the middle part of the valve rod bears stronger action pressure, and the two ends of the valve rod are stressed less, if a cylindrical valve rod is adopted, the problem of larger cost of the valve rod exists. Disclosure of Invention The utility model aims to provide a valve structure suitable for high-temperature high-pressure working conditions, which can solve the problems and can select a smaller-sized executing mechanism. According to the technical scheme, the valve structure suitable for the high-temperature and high-pressure working condition comprises a valve body and a valve rod, wherein the middle part of the valve rod is a reinforcing rod part, the two ends of the valve rod are conventional rod parts, a valve plate base assembly is arranged on the periphery of the reinforcing rod part, a medium hole is formed in the middle of the valve body, valve body holes are formed in the two sides of the medium hole, the valve plate base assembly is positioned in the medium hole, the conventional rod part is rotatably arranged in the valve body hole, and a sealing surface is arranged between the valve body and the valve plate base assembly.
