Description

High-temperature-resistant corrosion-resistant valve seat based on composite material Technical Field The utility model relates to the technical field of valve seats, in particular to a high-temperature-resistant and corrosion-resistant valve seat based on a composite material. Background In the field of industrial production, valves are used as key control components in fluid delivery systems, and the stability and reliability of their performance directly affect the safety and efficiency of the entire production process. Particularly, under severe working conditions of high temperature and strong corrosion, valve seat materials of common valves are difficult to meet the use requirements, and problems of insufficient high temperature resistance, poor corrosion resistance and the like are easy to occur, so that the service life of the valves is greatly shortened, the maintenance cost and the downtime of equipment are increased, and safety accidents can be even caused in severe cases. The existing valve seat materials, such as some traditional metal materials, have certain advantages in terms of strength, but are easy to creep and oxidize in a high-temperature environment to reduce the sealing performance of the valve, while some nonmetallic materials have certain corrosion resistance, but have the problems of softening, deformation and the like in a high-temperature condition, so that the normal operation of the valve cannot be ensured. In addition, the existing valve also has some defects in the aspect of connecting the guide pipe, such as inconvenient connection mode, poor connection stability and the like, and brings a plurality of inconveniences to the installation, disassembly and overhaul work of staff, meanwhile, in the long-term use process of the valve, the problem that the connection parts of the valve seat and the guide pipe and the like are easy to loosen, leak and the like further influences the use effect of the valve, so that the high-temperature-resistant and corrosion-resistant valve seat based on the composite material is provided.
