Pneumatic ball valve closed lax will lead to production is affected by the obvious, therefore in use process need special attention to these details, so how do we solve the problem of pneumatic ball Industrial Valves closed lax? Factory under the belt you know it. Maximum flow capacity electric cutting ball valve: because of its streamlined dilettante and quarter-turn full control of reason, make the maximum volume is extremely high, flow capacity particularly big, small flow resistance, so you can use smaller more economic use of the valve size. Pneumatic cut-off valve biggest reliable ( Security) Sex: the body as a whole structure, strong and durable, operation is not affected by the pipeline pressure one, and can avoid the leakage of the valve body. Electric explosion-proof gate valves have excellent control characteristics: v-type ball valve is approximate equal percentage flow characteristic and up to 300:1 adjustable ratio. So the v-shaped ball valve can be in wide range of change provides precise control. The first. Sealing surface structure without preload pressure, valve seat sealing surface should be regularly check device can preload pressure, find a seal face ever leak or contact should be a little loose pressure Industrial Valves seat sealing surface, in the process of the preloading spring effect loss and replacement. In the second. Wrench, as between the stem and ball joint clearance, wrench has to the user, shut down and the ball less than 90 degrees of rotation Angle control and information leakage, limited protection agency of wrench, stem and a sphere model are mutually joint is loose and when clearance is too large, should repair, fastening tightly; Adjust good state limit block, remove the adjustable wrench is advance Angle, make sphere form the correct opening and closing. In the third. Sphere rushed over and assembly should be correct, smooth operation, does not allow for the use of throttle valve parts, ball impact should be processed in a timely manner after the repair, replacement of different seal seat. In the fourth. Crushed on sealing surface, tighten the seat bolts should be uniform, force is smaller, the better to close a few times more, inevitably a tight too much time is too tight, damage the sealing surface of crapping to repair can be performed. Manufacturers think pneumatic ball valve closed lax, therefore, need to find out the problem, timely solve, avoid affect the normal use. 。
