Pneumatic butterfly valve characteristics and use environment, as well as procurement precautions, and maintenance of the detailed introduction
1. Characteristics of pneumatic butterfly valve
Pneumatic butterfly valve is a kind of pneumatic actuator driven disc valve, 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, semi-fluid and other media control;
(3) small flow resistance, fluid resistance is small, in large caliber and low pressure loss occasions have superior performance;
(4) Zero leakage, usually using triple seal structure, can achieve zero leakage effect;
(5) Long service life, simple maintenance.
2. Use environment of pneumatic butterfly valve
Pneumatic butterfly valve is suitable for the following environments:
(1) Temperature range: -20¡æ~+120¡æ;
(2) Pressure range: 0.6MPa~1.6MPa;
(3) Media: water, sewage, oil, gas, chemicals, etc.;
(4) Industries: petroleum, chemical, metallurgy, electric power, pharmaceutical, food, etc.
3. Pneumatic butterfly valve procurement precautions:
(1) Confirm the specification, model, material and driving mode of pneumatic butterfly valve;
(2) Check whether the working pressure and temperature range of the pneumatic butterfly valve meet the requirements;
(3) Confirm whether the sealing structure of the pneumatic butterfly valve can meet the requirements;
(4) To understand the reputation of pneumatic butterfly valve manufacturers, after-sales service is perfect, the purchase of guaranteed products.
4 pneumatic butterfly valve maintenance
(1) Regularly check the seal of the pneumatic butterfly valve, corrosion, etc., timely treatment;
(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 pneumatic butterfly valve is clean and prevent the intrusion of impurities;
(5) Regularly clean the internal parts of the pneumatic butterfly valve and replace the parts with serious wear;
(6) The maintenance of hydraulic and pneumatic systems must be carried out by professionals.
