Electric butterfly valve characteristics and use environment, as well as procurement precautions, and maintenance of the detailed introduction

1. Characteristics of electric butterfly valve
Electric butterfly valve is a butterfly valve driven by electric actuator, which has the following characteristics:
(1) Simple structure, small volume, light weight, flexible opening and closing, convenient installation;
(2) reliable sealing, a variety of sealing materials, used for gas, liquid, powder and other media control;
(3) small flow resistance, fluid resistance is small, in large caliber and low pressure loss occasions have superior performance;
(4) High control precision, can accurately control the flow rate and pressure of fluid;
(5) Long service life, simple maintenance.
2. Use environment of electric butterfly valve
Electric butterfly valve is suitable for the following environment:
(1) Temperature range: -40¡æ~+200¡æ;
(2) Pressure range: 0.6MPa~6.4MPa;
(3) Media: water, sewage, oil, gas, chemicals, etc.;
(4) Industries: petroleum, chemical, metallurgy, electric power, pharmaceutical, food, etc.
3. Purchasing precautions of electric butterfly valve:
(1) Confirm the specification, model, material and driving mode of the electric butterfly valve;
(2) Check whether the working pressure and temperature range of the electric butterfly valve meet the requirements;
(3) Confirm whether the sealing structure of the electric butterfly valve can meet the requirements;
(4) To understand the reputation of electric butterfly valve manufacturers, after-sales service is perfect, choose guaranteed products.
4. Maintenance of electric butterfly valve
(1) Check the seal and corrosion of the electric butterfly valve regularly and deal with it in time;
(2) When replacing the sealing material, the material suitable for the medium should be selected and the lubricant should be used reasonably;
(3) Check whether the connecting bolts of the valve and driving device are loose, and remove dust and foreign matter;
(4) Ensure that the working environment of the electric butterfly valve is clean and prevent the intrusion of impurities;
(5) Regularly clean the internal parts of the electric butterfly valve, and replace the badly worn parts;
(6) The electrical system maintenance of the electric butterfly valve must be carried out by professionals.
