Description
Technical Field
The utility model relates to a high temperature high pressure governing valve equipment technical field particularly, relates to a high temperature high pressure composite seal device.
Background
In the automatic control of modern plants, control valves play a very important role, and the production of these plants depends on the correct distribution and control of the flowing medium. These controls, whether energy exchange, pressure reduction, or simple vessel charging, require some final control element to accomplish. The regulating valve acts as a variable resistance in the conduit.
The sealing form of the existing regulating valve usually adopts devices such as a graphite gasket, a PTFE gasket and the like, but the devices such as the graphite gasket, the PTFE gasket and the like can not meet the normal sealing of the valve body under the working condition of high temperature and high pressure, and the leakage of the product is easily caused. There is currently no effective solution to this problem.
