What are the safety instructions of electronic pneumatic regulators?

In the field of industrial processing, people usually use electronic pneumatic regulators, the application of these instruments is very important, control instruments can ensure the accuracy of production and processing, so the staff in the daily work will control the application of instruments as one of the important content. The electronic pneumatic regulator is an industrial 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, the structure is very reasonable, so when using pneumatic adjustable valve installation is very convenient.

Here is the content list:

  • Pay attention to the installation of equipment

  • Verify that dirt has been removed

  • Determine the working conditions of the electronic pneumatic regulator

Pay attention to the installation of equipment

Although the operation method is very simple when using the electronic pneumatic regulator, in order to ensure that the pneumatic regulator is more efficient when using, the staff need to pay attention to the installation and use of the equipment. When installing an electronic pneumatic regulator should make sure the good installation height, can't adjust the installation position of the air and ground too close, pneumatic control valve should keep a certain distance and on the ground, the other device also needs to set aside a certain size, the advantage is in pneumatically adjustable air valve problems facilitate maintenance operations.

When installing the electronic pneumatic regulator, a certain support structure should be added below the device, so that the pneumatic valve can be more reliable during the operation. Some production units should avoid the generation of additional stress when fixing the equipment because of the special environment.

Verify that dirt has been removed

Foreign bodies in the electronic pneumatic regulator may damage the sealing surface of the valve or even obstruct the movement of the spool, ball, or disc and cause the valve to fail to close properly. To minimize the possibility of hazardous conditions, clean all piping, including metal debris, welding slag and other foreign bodies, prior to valve installation. Also, check the piping to make sure it has a smooth gasket surface. If the valve has threaded ends, apply a high grade of pipe sealant to the male thread of the pipe. Do not apply a sealant to female threads as the excess sealant will be squeezed into the valve body on female threads. The excessive sealant will cause the spool jam or dirt accumulation, which will lead to the electronic pneumatic regulator can not shut down properly.

Determine the working conditions of the electronic pneumatic regulator

Make clear the purpose of the electronic pneumatic regulator in equipment or device, and determine the working conditions of pneumatic regulator valve: applicable medium, working pressure, working temperature and so on. Determine the nominal diameter and connection method of the pipe connected with the pneumatic control valve: flange, thread, welding, etc. Modes of movement can be divided into straight stroke and angular stroke two ways. Choose the type of electronic pneumatic regulator: closed circuit pneumatic control valve, regulating pneumatic control valve, safety pneumatic control valve. Also to determine its parameters: for electronic pneumatic regulators, according to different needs to determine the first allowable flow resistance, discharge capacity, back pressure, etc., and then determine the nominal diameter of the pipe and the diameter of the valve seat hole.

The characteristics of the electronic pneumatic regulator are simple to control, rapid response, and essential safety, no need to take additional explosion-proof measures. Visit NNT's website for more information.
