Hard seal ball valve, ball core, including body seat, shaft and guide sleeve, its characteristic is that the ball core, adopting the fixed support structure in the product of the seat contact with the ball core is equipped with a convex sets, in the product of the seat sealing surface with ball core installation has a lip seal type; Beside the product guide sleeve are installed on the axis of the seal. This product technical solution to solve the GSP technology of pulverized coal conveying special ball valve sealing unreliable, seal surface hardening layer falls off easily, the problem of large torque, at the same time solve the problem of the guiding parts easy to damage, but also improves the ability of valve abnormal anti jamming, need not with special pipeline purging gas. Matters needing attention are: 1, hard seal ball valve in the closed state, the body still exist inside pressure fluid before 2, maintenance, remove line pressure and make the valve is in open position 3, assembly flange bolts must be symmetrical, gradually and evenly tighten 4, the assembly should not be allowed to have metal scraps, fiber and fat ( With the provisions of the exception) Dust and other impurities, foreign bodies, such as pollution, adhesion, or stay in part on the surface or into the inner cavity 5, you must first find out on the ball valve, the downstream piping have indeed after unloading the pressure, dismantling operations to 6, decomposition, and then assembly must be careful to prevent damage the sealing surface of the parts, especially the nonmetallic parts, remove the o-rings inappropriate use of special tools before 7, maintenance, electricity or gas 8, cleaning agents should be disconnected from ball Industrial Valves in the rubber 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 9, break down the single parts can use dip way 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. 10, non-metallic parts shall be immediately removed from the cleaning agent, after cleaning shall not soak for a long time after 11, cleaning after wash wall cleaning agent to volatilize and ( Available not soak cleaner silk cloth to wipe) Are assembled, but shall not be shelved for a long time, or it will rust, dust contamination 12, 13 new parts also need to be cleaned before assembly and 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. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on the rubber seal, Industrial Valves stem seal face and friction surface coated with a thin layer of grease before 14, maintenance, the actuator (with support from thank you for visiting our web site www。 quanlivalve。 com】 , if you have any questions, you can call us, we will be dedicated to provide you with quality services.
