[0003] The anti-surge governing valve is a kind of device specially designed to prevent the surge phenomenon of centrifugal gas compressor during operation, surge refers to the phenomenon that the outlet pressure of compressor suddenly rises when the flow rate decreases to a certain value, resulting in unstable operation of the compressor. To prevent surge, the anti-surge governing valve automatically adjusts the opening of the valve to ensure that the compressor operates within a safe flow range. Its working principle is to monitor the outlet pressure and flow rate of the compressor. When the flow rate decreases to the lower limit of the safe range, the bypass valve or vent valve is automatically opened to increase the flow rate through the compressor, thereby preventing the compressor from entering the surge zone. However, during use, the sealing material of the anti-surge governing valve may be affected by temperature, pressure and chemical corrosion of the fluid medium during long-term use, which may cause the sealing surface to not fit tightly, resulting in leakage. In the prior art, for harsh working conditions such as high temperature and high pressure, metal sealing materials such as hard alloy and stainless steel can be used, and special surface treatment processes such as spraying and surfacing can be used to improve the hardness and smoothness of the sealing surface, thereby enhancing the sealing performance.
