Plastic as pneumatic valve using method

plastic by the pneumatic valve has been widely used in water, air, oil, corrosive liquid chemical fluid, such as user's market attention.

plastic used as pneumatic valve method open/close by the pneumatic valve, strength should be smooth, not impact. Some impact open/close the high-pressure pneumatic valve parts is considered as the the impact and generally by the pneumatic valve can't wait. After the RPP plastic by the pneumatic valve fully open, should reverse a little hand wheel, between the screw thread, so as to avoid looseness damage. At the beginning of the line, internal dirt is more, RPP plastic by the pneumatic valve can be tiny qi, using high speed flow of medium, it washed away, then gently close ( Cannot be quickly closed, slammed shut to prevent residual impurities task of sealing surface) , once again open, repeat many times, clean dirt, back into work. Normally open RPP plastic by the pneumatic valve, sealing surface may stick with dirt, closed and want to use the method to be washed clean, and then formally locked. Such as the handwheel, handle the damage or loss, shall be immediately to match neat, do not replace with adjustable wrench, so as not to damage the pneumatic valve rod, opening and closing is ineffective, so that accidents in production. Some medium, pneumatic valve closed after cooling, the deadline for the submission of plastic shrinkage of pneumatic valve, operators should be in the appropriate time to close it again, let the sealing surface crack, leaving no otherwise, medium thin seam high-speed flow, it is easy to erosion seal face. Operations, such as found too difficult operation, causes should be analyzed. If the packing is too tight, can relax appropriately, such as pneumatic valve stem skew, personnel shall be notified to repair. Some by the pneumatic valve, when closed, closed heat expansion, open the difficulties; If must open at this time, can be pneumatic valve cover screw loosen to half a circle a circle, eliminate stress, pneumatic valve stem and plate hand wheel.
