Antifouling valve
The theoretical premise of general valve design is to work in clean gas source condition. When air valves are used in large and miscellaneous gas industry and mines containing a lot of dust, tar and other pollutants, the pollutants in the gas are easy to adhere to the air valve flow groove, surface and spring hole; under high temperature and pressure, the carbon deposit layer is easily formed on the whole of the air valve, and the impurities in the spring hole are not discharged in time, resulting in abnormal or stuck spring operation, resulting in the decrease of the flow area of the air valve, improper sealing, gas escape, gas escape, and gas jam. Leakage and other phenomena. The service life of the valve is greatly shortened and the power loss is obvious, which is far from the theoretical design service life. This phenomenon is particularly evident in coal-based enterprises.
The anti-fouling coating gas valve is characterized by high temperature and anti-fouling coating on the whole surface of the valve. The coating has strong corrosion resistance and anti-adhesion, which reduces the retention of oil pollution on the surface of the valve, channel grooves and spring holes, and reduces the carbon deposition rate. The valve is designed as an anti-blocking valve. It has a wide channel inclined flow groove and matching air holes, which can effectively discharge oil and impurities, thereby improving the service life of the valve and reducing power loss. The valve is especially suitable for the operation of huge and impure gases containing dust, tar and other impurities.
