Pneumatic ball valve seal leakage problem

Pneumatic ball valve seal leakage problem


must be sealed pneumatic ball valve when the installation is processed, if the sealing is not good will cause the valve can't normal work.


sealing is not good reason:


1, pneumatic ball valve sealing ring connection may be loose screw, screw, pressure circle;


2, sealing ring and body welding, welding quality is poor.


3, pneumatic ball valve sealing ring connection and corrosion;


4, sealing ring rolling is lax.


the solution:


1, screw, compression ring cleaning, replacement of damaged parts, grinding seal and connection closed surface, repackaging. Of corrosion damage larger components, available methods of welding, bonding repair;


2, pneumatic ball valve sealing ring should be according to the welding specification to don't understand the repair welding. When unable to repair welding should be cleared the original welding and surfacing processing;


3, sealing ring junction surface corrosion, grinding are available, and bonding methods such as repair, repair in use should replace the sealing ring;


4, pneumatic ball valve sealing rolling leak should note adhesive rolling fixed again.
