Jacket type pneumatic valve ball points should be paid attention to during maintenance

, only removable jacket type pneumatic valve ball pressure before and after, to dismantling operations for the jacket type pneumatic valve ball. Pneumatic valve, on the jacket type ball decomposition and assembly process again, need to have the protection of the sealing parts, especially non-metal components, parts like o-rings it is best to use special tools. And jacket type pneumatic valve pneumatic ball valve to assembly to tighten bolts must be symmetrical, gradually and evenly. Should, cleaning agents and jacket type pneumatic valve ball of rubber parts, plastic parts, metal parts and working medium ( For example, gas) Are incompatible. Working medium is gas, can use gasoline ( GB - Clean the metal parts. 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 the cleaning agent, 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 parts also need to be cleaned before assembly. And use of grease lubrication. Grease and jacket type pneumatic valve ball 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. , the assembly should be there is no 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.
