Install the matters needing attention and the maintenance of pneumatic control valve

The maintenance of pneumatic control valve: as the regulator using the environment evil Shirley, hard to avoid appear some fault in use. Therefore, for certain control valve maintenance and maintenance is necessary. The main content of the pneumatic - valve daily maintenance should have the following: ( ) The body wall. Check the pressure, corrosion conditions. ( ) The seat. Because medium infiltration, fixed seat with the thread is susceptible to corrosion on the inner surface of the seat is loose, should be careful when checking. In high-pressure situations, still should check whether the valve seat sealing surface was broken to pieces. ( ) The valve core. Carefully check whether all parts of the valve core is corrosion, wear and tear, especially under the condition of high pressure differential valve core is more serious wear and tear, and should be pay attention to. Also had a similar phenomenon, should check whether the valve stem or connected to the valve core is loose, etc. ( ) Diaphragm, o-ring and other gasket. Check whether the aging and crack damage. ( ) Packing. Check whether the ptfe packing, sealing grease is aging, dry, mating surface is damaged. Pneumatic control valve installation using the matters needing attention in the field of industrial processes, and people can use pneumatic - valve control instrument at ordinary times, it is very important to the application of the instrumentation, control instrument can guarantee the production and processing precision, so the staff in daily work will be as one of the important contents of the application of control instrument. Pneumatic control valve is the industry process control instrument, is also often used in the production of equipment, equipment at work can be powered by compressed gas, the working principle of equipment is simple, structure is very reasonable, so when using pneumatic adjustable valve installation is very convenient. Although in the use of pneumatic control valve operation method is very simple, but in order to guarantee the pneumatic control valve in the use of more efficient, workers need to pay attention to equipment installation method of use. When installing pneumatic adjustable air valve should be installed make sure good height, pneumatic valve installation position can not be and too close to the ground, pneumatic control valve should keep a certain distance and the ground, the other device also need to set aside a certain size, the advantage is in pneumatic adjustable air valve problems facilitate maintenance operations. Pneumatic control valve installation, should increase certain support structure at the bottom of the device, so that we can make pneumatic valve more stable during operation, some production work environment is special because it is over, when fixed installation equipment should also avoid the generation of additional stress. Staff in the process of using pneumatic - valve at ordinary times, should pay attention to the dry degree of adjustable air valve installation environment, installation environment humidity shoulds not be too big, should also guarantee the channel is smooth, at ordinary times when installed using pneumatic - valve must pay attention to these problems.
