Plastic globe valve is now widely used in water, air, oil, corrosive chemical liquids and other fluids, much market users widespread concern. Plastic stop valve method of use Opening and closing the globe valve, force should be smooth, can not impact. Some of the impact of opening and closing of the high-pressure globe valve components have been considered this impact and the general cut-off valve can not wait for Gang. When the RPP plastic shut-off valve fully open, the hand wheel should be reversed a little, so tight between the threads, so as not to loosen the damage. At the beginning of the pipeline, there are many internal dirt, RPP plastic globe valve can be micro-Kai, the use of high-speed flow of media, it washed away, and then gently shut down (can not quickly closed, Meng closed to prevent residual impurities folder seal Surface), open again, so repeated several times, rinse the dirt, then put into normal work. Often open RPP plastic globe valve, the sealing surface may be stuck with dirt, shut down also use the above method to flush it clean, and then officially closed. Such as the hand wheel, the handle is damaged or lost, should be immediately fitted, can not be replaced by the board wrench in order to avoid damage to the stem square, opening and closing ineffective, resulting in an accident in production. Some media, after closing the plastic shut-off valve to cool, the valve contraction, the operator should be closed again at an appropriate time, so that the sealing surface without fissure, or medium flow through the slit at high speed, it is easy to erosion Sealing surface. Operation, if found to be too strenuous operation, should analyze the reasons. If the packing is too tight, may be appropriate to relax, such as stem skew, should notify the staff to repair. Some shut-off valve, in the closed state, the closure of the thermal expansion, resulting in difficult to open; If you must open at this time, the valve cap can be loosened to a half circle to a circle, eliminating the stem stress, and then the plate wheel.
