Treatment method and daily maintenance of leakage of electric valve gearbox

The action force distance of electric valve is larger than that of ordinary valve. The opening and closing speed of electric valve can be adjusted. It has simple structure and easy maintenance. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metal and radioactive media. Electric valves are usually composed of electric actuators and valves. The electric valve uses electric energy as power to drive the valve through the electric actuator to realize the opening and closing action of the valve, so as to achieve the purpose of opening and closing the pipeline medium.
Electric valve is a necessary tool to reduce workers' labor intensity and solve the harsh working environment. In its working process, various leakage problems are often caused due to vibration, temperature, seal aging and other reasons, such as gearbox leakage. If not handled in time, it will not only cause environmental pollution, but also have potential safety hazards. When an enterprise encountered the leakage problem of electric valve gearbox, it was treated with soray carbon nano polymer material. The material is a high-performance polymer material reinforced by carbon nano materials. Its advantage is that it can be cured quickly at low temperature (- 20 ℃ - 0 ℃) or in humid environment. It can deal with the leakage problem in various environments, and can be well adhered to various metals, concrete, glass, plastic, rubber and other materials.
In order to ensure the safe and stable operation of electric valves, we should not only find problems and deal with them in time, but also pay attention to daily maintenance, such as:
The electric valve shall be stored in a dry and ventilated room, and both ends of the passage must be blocked.
Electric valves stored for a long time shall be inspected regularly, dirt shall be removed, and anti rust oil shall be coated on the processing surface.
After installation, regular inspection shall be carried out. Main inspection items: wear of sealing surface; Wear of stem and trapezoidal nut; Whether the packing is out of date and invalid. If it is damaged, it shall be replaced in time; After the maintenance and assembly of the electric valve, the sealing performance test shall be carried out.
For electric valves in operation, various valve parts shall be complete and intact. It is not allowed to knock, stand or support heavy objects on the running electric valve; In particular, non-metallic electric valves and cast iron electric valves should be prohibited.
