For the shut-off valve , the external leakage is still handled well. For the middle flange leakage, tighten the bolt of the middle flange. If it is not enough, open it to see if the flange gasket is damaged. Leakage, it is necessary to close the packing gland. If the packing is too loose, it is necessary to add the packing. If it is directly leaking on the body, it can be welded under low pressure. If it is high pressure, give it up directly, safety first, for the internal leakage problem. The situation is not sure. First, it may not be closed, and then shut down with force. Second, the valve seat seal is damaged. This will be re-grinding. If the valve core is damaged, it depends on whether it is damaged by the medium or damaged by the medium. , but both must re-weld the sealing surface.
The internal leakage is generally damaged by the valve seat or the sealing surface of the valve core. This can grind the valve seat or the sealing surface of the valve plug. However, there is an special case that if the electric or pneumatic is used, the valve stroke may not be set. The external leakage depends on what is leaking. If the valve body leaks, it can only change the valve.
If there is an internal leak, there should be a problem with the sealing surface.
If the leak occurs, the valve is different and the leak position is different.
If the packing leaks outside, if it is tight or replace the packing, we often use the pressure plugging to stop the parking.
There are many leak points in the shut-off valve. In most cases, the leak is leaking from the gland. When the gland is opened or replaced, the gland should be replaced and the gland should be tightened. The internal leakage is that the sealing surface on the inside of the valve core is broken, but the actual experience tells us that sometimes the internal leakage may be stuck on the valve core, causing internal leakage. The specific treatment method is to open and close the valve. It is enough to wash away the hard objects several times. If it is a problem with the valve itself, choose the right time to replace the valve.
