In the process of using pneumatic ball Industrial Valves, influenced by many factors, will encounter a lot of different faults, so these failures? 吗? Manufacturers will take you to correct the valve failure. Carbon steel check valve is the valve is used as boiler feed water and steam to cut off the valve, it can lift check valve and globe or Angle valves of the comprehensive function. American standard check valve according to the conditions of use, Industrial Valves can be all-metal structure, can also be embedded in disc shelves rubber mat or rubber ring form. Forged steel check valve used for industrial piping block medium counter-current device. Pneumatic valve in the closed state, the body still exist inside pressure fluid pressure. Prior to servicing the Industrial Valves, must remove pipeline internal pressure and the valve is in open position, disconnect the electricity or gas, pneumatic actuators and stand out. And then split the work can proceed to repair. Pneumatic valve is evolved by the cock. It rotates 90 degrees with the same action, different is the cock body is ball, has a circular hole passage through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow. Pneumatic valve just has to rotate 90 degrees of operating and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Decomposition and repackaging must be careful to prevent damage the sealing surface of the parts, especially the nonmetallic parts, take out the appropriate use of special o-rings with tools, reassemble the valve flange bolts must be symmetrical, gradually and evenly tighten, cleaner with pneumatic valve of rubber parts, plastic parts, metal parts and working medium etc are incompatible. Non-metallic parts with pure water or alcohol cleaning medium is gas, cleaning metal parts available petrol. 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 scrub of silk. When cleaning should remove all adhesion on the surface of grease, dirt, plastic product, dust, etc. Assembly time should not be allowed to have metal scraps, fiber dust, grease and other impurities, foreign bodies, such as pollution, adhesion, or stay on the parts surface, or into the lumen. If the filler has a small leakage occurs, the stem nut should be locked. So said problems pneumatic ball valve failure, must be timely find out the fault, and you can use the student correct method research is analyzed.
