electric ball valve consists of electric actuator and valve electric ball valves, is one of the industrial automation process control pipe pressure components, usually used for pipeline medium (remote, Through, to cut off the medium) Control. factory types are: the electric ball Industrial Valves floating ball valve, the fixed ball ball Industrial Valves, ball valve, v-shaped ball valve, three-way ball valve, stainless steel ball valves, forged steel ball valve, sulfur discharge ball valve, ball valve, three-way ball valve, pneumatic ball valves, electric ball valves, card sets of ball valves, welding ball valve, flanged ball valves, threaded ball valve. Now many people don't know how to maintain after bought electric ball valves, led to the short service life of electric ball valves, frequent replacement, such as the following valve co. , LTD. Will introduce electric ball valve of some of the maintenance of common sense. 1, the use of grease lubrication. Grease and ball valve should be metal material, rubber parts, plastic parts and working medium are incompatible. Working medium is gas, available for example 221 grease. On the surface of the seal installation groove grease, grease on rubber seal, valve stem seal face and friction surface coated with a thin layer of grease. 2, decomposition and assembly again when the sealing surface of the parts, must be careful to prevent injury especially non-metal parts, o-rings inappropriate use of special tools. 3, the new parts also need to be cleaned before assembly. 4, cleaner should be with the rubber ball valve parts, plastic parts, metal parts and working medium ( For example, gas) Are incompatible. Working medium is gas, can use gasoline ( GB484 - 89). Clean the metal parts. Non-metallic parts clean with clean water or alcohol. 5, the 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. 6, break down of a single component can use the way of baptism to clean. 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. 7, non-metallic parts after cleaning shall be immediately removed from the cleaning agent, may soak for a long time. 8, the assembly on the flange bolts must be symmetrical, step by step, to tighten evenly. 9, after wash wall cleaning agent to volatilize and after cleaning, Available not soak cleaner silk cloth to wipe) Assembly, but shall not be shelved for a long time, or it will rust dust contamination. 10, must first find out the electric ball valve, the downstream piping have indeed after unloading the pressure, to carry out dismantling operations.
