Maintenance methods of various ball valves

In the long-term use and management process of various safety valves, the enterprise may be damaged at the same time as the electric stainless steel flange ball valve, so how should we manage it? The manufacturer suggests to take you to know the maintenance method of the valve. The 33V electric valve has good self sealing and self sealing performance, and is a metal stop valve with long service life. Electric explosion-proof ball valve is widely used in petroleum, chemical, electric power, paper, metallurgy and other industries. Pneumatic knife gate valve is a right angle rotary regulating valve used with valve positioner.

1. The soft seal ball valve is usually used as the sealing material, while the hard seal ball valve is sealed with metal surface. When the pipeline ball valve needs to be cleaned, care should be taken during disassembly to prevent damage and leakage of the seal

2. In the process of use, if the filler has slight leakage, please slightly tighten the stem nut before stopping the leakage, and do not tighten it again.

3. Before use, clean the pipe and the flow passage parts of the body with water to prevent the residual iron filings and other debris from entering the body cavity.

4. The ball valve is closed, the valve keeps part of the medium and bears a certain pressure.

5. Long term outdoor storage before maintenance of the ball valve will rust the valve body and parts, which can not be used normally. The storage of the ball valve is rainproof, waterproof, moisture-proof, and the tightness of the flange cover

6. If slight leakage of filler is found during use, the valve stem nut shall not be tightened until the leakage stops

Therefore, depending on the situation, different maintenance balls need to be performed to ensure the performance of the ball.
