Pneumatic flanged ball valves in use process, influenced by various factors, therefore, its service life will be falling, so in order to avoid the pneumatic flanged ball valves service life, which need to pay attention to details in use? 吗? What method? 吗? 1, in the use of pneumatic valve, often should keep clean, drive screw must be lubricated periodically, find fault, should immediately stop using, find out the reason to remove fault. Lift check valve can be divided into main swing check valve ( In accordance with the center of gravity rotating) And lift check valve ( Move along the axis) 。 Carbon steel check valve is the valve is used as boiler feed water and steam to cut off the valve, it can lift check valve and globe or Angle valves of the comprehensive function. High temperature check valve belongs to a kind of automatic valve, main effect is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium. 2, pneumatic valve open and close at hand wheel, lever, or through other tools do not, in order to avoid damage to the valve components. The handwheel clockwise closing, otherwise it is open. 3, the use of pneumatic valve in the fully open or fully closed only, flow control, are not allowed to do so by the corrosion of the sealing surface, accelerated wear and tear. Gate valve and reverse screw sealing device, described the handwheel turning to the fastening position, to prevent the leakage from the packing media. 4, long-term storage of Industrial Valves shall be checked regularly exposed to processing surface should be clean, to remove dirt, ball valves shall be stored stated when the blocks at both ends and in conducting state, two ends of pneumatic Industrial Valves, and channel should be stopped in the closed position, neatly stored in a dry place indoor and ventilated, the stack or open account. 5, packing gland bolts shall be uniformly tight, should not be pressed into crooked state, in order to avoid collision incidents block Industrial Valves stem movement or cause information leakage. Therefore, in order to prolong the service life of pneumatic flanged ball valves, in use process, need to pay attention to these details, in order to ensure its good performance.
