- pneumatic ball valve Wear-resistant ball pneumatic valve in detail

wear-resistant ball series pneumatic valve is learnt hard seal ball pneumatic valve technology abroad and the design and manufacture, the use of special sealing structure, reliable sealing performance, achieve zero leakage. Sphere and pneumatic seat has good shearing self-cleaning function. Seal with high wear-resistant tungsten carbide alloy hardening technology for processing, with high hardness and wear resistance performance, service life is times more than conventional metal sealing ball pneumatic valve, appearance is still maintain normal pneumatic valve ball and beautiful shape, particularly suitable for power plant dust removal, blast furnace pulverized coal ash discharge, conveying system, polycrystalline silicon, organic silicon and other special conditions, thoroughly solved the long plagued the pneumatic valve is easy to wear in the system, the problem of frequent replacement, will save the purchasing cost, and can reduce system downtime caused economic losses. Wear-resistant ball pneumatic valve is typically used for power plant boiler ash discharge, kuangfen, pulverized coal transportation, paper pulp pump, etc. , super wear-resistant ball pneumatic valve is typically used for organic silicon, polycrystalline silicon, mineral powder conveying, pulverized coal injection coal, shows that slurry pump and so on.
wear-resistant ball pneumatic valve wear-resistant pneumatic valve series two kinds, one kind is through the permeability tungsten carbide wear-resistant alloy to pneumatic valve sphere surface, increase the hardness of a sphere, to increase its wear resistance, make the medium particles by a pneumatic valve line, can resist medium of pneumatic valve body especially spherical and the sealing ring of erosion abrasion, and increase its service life, its hardness is usually chromium hardness - In between. Another major categories by supersonic flame spraying and flame spraying equipment to the sphere surface spraying tungsten carbide wear-resistant alloy, the hardness of - Between, can resist abrasion of larger particles of medium hardness, such is the dragon air produced super wear-resistant ball valve pneumatic valve. In addition, we also provide customers tailored, personalized service, to provide non-standard structure and import substitution design and production. Usually in understanding the operation condition of the products that users need, medium, temperature, pressure and other requirements and make a selection, but also consider its price as far as possible cost savings for customers. Wear-resistant ball temperature can reach of the pneumatic valve, using one-way seal form. Such as manual, electric and pneumatic drive way. Nominal diameter: DN - , nominal pressure. - 。 MPa, applicable temperature: - ℃, ℃, material: WCB, and etc. Pneumatic ball valve repair assembly must first find out the wear-resisting ball on the pneumatic valve, the downstream piping have indeed after unloading the pressure, to carry out dismantling operations. ( Decomposition and assembly again when the sealing surface of the parts, must be careful to prevent injury especially non-metal parts, using a special tool to take out the o-rings. ( Assembly the flange bolts must be symmetrically, gradually and evenly. ( Cleaner should with steel ball of the pneumatic valve rubber parts, plastic parts, metal parts and working medium ( For example, gas) Are incompatible. Working medium is gas, cleaning metal parts available petrol. Non-metallic parts clean with clean water or alcohol. ( 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. ( Non-metallic parts after cleaning shall be immediately removed from cleaner, may soak for a long time. ( After wash wall detergent volatilization and after cleaning, Available not soak cleaner silk cloth to wipe) Are assembled, but shall not be shelved for a long time, or it will rust and dust pollution. ( The new pneumatic ball valve parts also need to be cleaned before assembly. ( Use of grease lubrication. Grease and pneumatic ball valve should be metal material, rubber parts, plastic parts and working medium are incompatible. Working medium of gas, available such as grease. Besmear in seal installation groove on the surface of a thin layer of grease, apply a thin layer of grease on the rubber seals, pneumatic valve stem seal face and friction surface coated with a thin layer of grease. ( Assembly time 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.
