Deyue Valve focuses on the production, manufacturing, sales and service of hard sealing wear-resistant ball valves, electric high-performance ball valves and hydraulic eccentric hemisphere valves.
The causes of internal leakage of eccentric hemisphere valve are as follows: 1. Improper pigging will damage the sealing surface and cause internal leakage; 2. If the ball valve is not maintained regularly as required or the maintenance method is improper, the ball valve may leak in advance; 3. If the ball valve is not maintained or moved for a long time, it will inevitably lead to damage of the sealing surface and internal leakage when opening and closing the eccentric hemisphere valve; 4. During the long-term operation of the ball valve, the valve rod or extension rod will rust and fall off, preventing the ball valve from rotating in place, which can lead to the ball valve not being opened and closed in place, resulting in internal leakage; 5. Improper operation, long-term use of eccentric hemisphere valve for flow and pressure regulation, long-term scouring of the sealing surface is likely to damage the spherical surface and sealing surface, resulting in internal leakage; 6. The ball valve is lack of regular maintenance, which causes the sealing grease to become dry and hard. The dried sealing grease accumulates behind the elastic valve seat, hinders the movement of the valve seat, and leads to seal failure. The above is the reason for the internal leakage of the eccentric hemisphere valve. You can learn about it. If you need friends, you can consult Wenzhou Jiadian Machinery Manufacturing Co., Ltd.
