When high voltage hard seal ball valve in the operation and maintenance, should pay attention to some matters, a total of 12 points, specific as follows: 1, high voltage hard seal ball valve in the closed state, the body still exist inside the pressure fluid; 2, maintenance, remove line pressure and the valve is in open position; Disconnect the power supply or source; The actuators and stand out; 3, you must first find out on the ball valve, the downstream piping have indeed after unloading the pressure, to dismantling operation; 4, decomposition, and then assembly must be careful to prevent injury when sealing surface of the parts, especially the nonmetallic parts, remove the o-rings inappropriate use of special tools; 5, when assembly flange bolts must be symmetrical, gradually and evenly tightened; Six, cleaning agents should be with the rubber ball Industrial Valves parts, plastic parts, metal parts and work medium are incompatible. Working medium is gas, cleaning metal parts available petrol. Non-metallic parts clean with clean water or alcohol 7, break down of individual parts can clean with dip way, still left did not break down the non-metallic metal parts can be fine clean clean immersion cleaner silk ( In order to avoid fall off fiber adhesion on the parts) Scrub, when cleaning should remove all adhesion on the surface of grease, dirt, plastic product, dust, etc. ; 8, non-metallic parts shall be immediately removed from the cleaning agent, after cleaning must not soak for a long time; 9, after cleaning after wash wall detergent volatile and are assembled, but shall not be shelved for a long time, or it will rust and dust pollution; 10, the new parts also need to be cleaned before assembly; 11, the use of grease lubrication, grease and ball Industrial Valves should be metal material, rubber parts, plastic parts and working medium are incompatible. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on rubber seal, valve stem seal face and friction surface coated with a thin layer of grease; 12, assembly should not be allowed to have metal chips, fiber, fat ( With the provisions of the exception) Dust and other impurities, foreign bodies, such as pollution, adhesion, or stay on the parts surface or into the lumen.
