As we all know, ball valves are widely used in chemical, petroleum, metallurgical and other fields, and the inner wall of the prevailing fully welded ball valve is extremely smooth. In the process of conveying the medium of the ball valve, the friction between the inner wall of the ball valve and the medium is very small, and the medium can pass unimpeded, however, the fully welded ball valve will be affected by some factors in operation.

First, the influence of sealing materials

In the actual working conditions, the fully welded ball valve is generally through various gases as the medium: such as natural gas, gas, gas, chemical industry, heating, heating, etc., the temperature of these media is generally between -20 °C -150 °C, and the nominal pressure is PN16-25 pressure, soft seal can meet the requirements, but the quality of soft sealing material is not hard, it is easy to cause medium leakage. And due to the serious wear and tear of the medium operation, over time, the service life of the fully welded ball valve is greatly reduced.

Second, the impact of processing technology

The overall quality of various fully welded ball valve spools will be determined by the processing technology, and the thickness of the wear-resistant layer of the molded hose is uneven, which is easy to break the thin first. Therefore, the wear resistance and acid and alkali resistance of the ball valve will become very poor, which can only meet the general working conditions, and the spool of the fully welded ball valve using high-quality technology can well ensure the wear-resistant layer and uniform cloth thickness.

Third, the impact of material corrosion

Affected by the corrosion of the valve body, the opening and closing mechanism is damaged, and the valve body is poorly worked, resulting in the driving device, pneumatic or electric actuator of the fully welded ball valve often closed too tightly or can not be completely closed, and the rust of the material of the fully welded ball valve will greatly reduce the service life of the workpiece.

In summary, the main influencing factors of the all-welded ball valve in the process of use are sealing materials, processing technology, material corrosion, etc., so in the process of selecting and using high-quality all-welded ball valves, users need to carefully study the manufacturing process and materials of all-welded ball valves, and make reference choices according to actual applications.
