What Should I Do If The Factory Pneumatic Ball Valve Is Closed?

Update time:2021.11.16       Views:251

 If the pneumatic ball valve is not closed tightly, the production will be obviously affected. Therefore, you need to pay special attention to these details during use. Then how do we solve the problem of the pneumatic ball valve not being tightly closed? The manufacturer will take you to understand it. The maximum flow volume of the electric cut-off ball valve: Due to its streamlined layman and full right-angle rotation control, the maximum volume is particularly high, the flow capacity is particularly large, and the flow resistance is small, so a smaller and more economical valve size can be used . The maximum reliability (safety) of the pneumatic shut-off valve: the valve body is an integral structure, sturdy and durable, the operation is not affected by the pipeline pressure, and the leakage of the valve body can be avoided. The electric explosion-proof gate valve has excellent adjustment characteristics: the V-shaped ball valve has an approximate equal percentage flow characteristic and an adjustable ratio of up to 300:1. Therefore, the V-shaped ball valve can provide accurate control in a wide range of changes.


First. The sealing surface has no pre-tightening structure pressure. The valve seat sealing surface should be regularly organized to check the pressure of the pre-tightening device. If there is any leakage or loose contact on a sealing working surface, the valve seat sealing surface should be slightly compressed. The pre-compression process The spring failure should be replaced as well. Second. There is a large gap between the wrench, valve stem and ball as the connection between the three, the wrench has reached the user's closed position, and the rotation angle of the ball is controlled less than 90 degrees, resulting in information leakage, the wrench, valve stem and ball of the limit protection mechanism When the connection between the three models is loose and the gap changes too much, it should be repaired and tightened firmly; adjust the state limit block to eliminate the advance angle of the adjustable wrench, so that the sphere is formed correctly to achieve opening and closing. Third. The ball is overturned, the assembly should be correct, and the operation should be stable. It is not allowed to be used as a throttle valve. After the ball is overturned, it should be repaired in time and replaced with a different seal seat. Fourth. If the sealing surface is crushed, the bolts at the valve seat should be tightened evenly and the force should be small. It is better to tighten it several times. It is inevitable that the sealing surface is too tight for too much time. The damaged sealing surface can be repaired by grinding.


Therefore, the manufacturer believes that the pneumatic ball valve is not closed tightly, and it is necessary to find out the problem and solve it in time to avoid affecting normal use..
