Vacuum pneumatic ball valve failure and solutions

vacuum pneumatic valve has long been affected by the material flush, friction, causing severe impact wear, cannot meet the normal production, at the same time, the equipment could shorten. The moment for pneumatic ball valve wear more adopts wear-resisting material, such as ceramic materials, application more technical system. Polymer materials with excellent tackiness, super wear resistance, safe solve the disadvantages of the metal often wear, ensure the normal production of enterprise devices. And materials of ceramic materials and the unique surface enhancer, dry ground in the worst environment impact abrasion resistance and resistance to physical performance even better than that of any steel than ceramic tile, product performance and the types of coal is an ideal material to prevent coal deposition.
vacuum butterfly pneumatic valve products have long service life and maintenance free, in daily use should pay attention to the following:
low pneumatic ball valve in the closed state, the pneumatic valve internal compression of remains fluid;
low maintenance, remove line pressure and pneumatic valve is in open position;
low maintenance, disconnect the power supply or source;
low maintenance, actuators and stand out;
low must first find out the pneumatic ball valve, the downstream piping have indeed after unloading the pressure, to carry out dismantling operation;
when low decomposition and assembly again sealing surface of the parts, must be careful to prevent injury especially non-metal parts, remove the o-rings inappropriate use of special tools;
low assembly when the flange bolts must be symmetrical, gradually and evenly tight;
low cleaner should with pneumatic ball valve of rubber parts, plastic parts, metal parts and working medium ( Such as gas are incompatible. Non-metallic parts clean with clean water or alcohol;
low break down individual 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 scrub on the parts. When cleaning should remove all adhesion on the surface of grease, dirt, plastic product, dust, etc. ;
low non-metallic parts shall be immediately removed from the cleaning agent, after cleaning must not soak for a long time;
low after wash wall cleaning agent to volatilize and after cleaning, Available not soak cleaner silk are assembled, but shall not be shelved for a long time, or it will rust and dust pollution;
when new parts also need to be cleaned before assembly;
low 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 should be not allowed to have metal chips, fiber, fat ( Regulations except use of dust and other impurities, foreign bodies, such as pollution, adhesion, or stay on the parts surface, or into the lumen.
