Description

Technical Field

[0002] Anti-corrosion valves are control components in pipeline fluid transportation systems. They are used to change the cross-section of the passage and the flow direction of the medium. They have functions such as diversion, shut-off, regulation, throttling, check, diversion or overflow. Valves used for fluid control range from the simplest shut-off valve to various valves used in extremely complex automatic control systems. There are many varieties and specifications of valves. The nominal diameter of the valve ranges from extremely small instrument valves to industrial pipeline valves with a diameter of up to 10m. Valves can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. There are many types of valves, among which butterfly valves are widely used in various medium and low pressure gas and liquid controls.

[0003] However, due to the flaky structure of the valve plate, the butterfly valve is prone to wear and corrosion, which reduces its strength. At the same time, butterfly valves are generally used in long-term exposure to air in a harsh operating environment, and the valves are prone to rust, which affects their service life.
