Wuxi Xinming self-control valve industry to introduce to you to keep these three aspects, yoursPneumatic control valvewill not present leaked questions. In the pneumatic control valve technology, the air filter, control valve and oil mist device three kinds of air source processing components are assembled together called pneumatic triplet, which is used to purify and filter the air source entering the pneumatic surface and reduce the pressure to the surface to supply additional air source pressure, which is equivalent to the function of the power transformer in the circuit. The valve limit switch is a kind of on-site appearance for detecting the valve condition in the control system. It is used to output the opening or closing position of the pneumatic control valve with the signal of the switch value (contact), which is accepted by the controller or searched and sampled by the computer.

In the pneumatic control valve technology, the air filter, control valve and oil mist device three kinds of air source processing components are assembled together called pneumatic triplet, which is used to purify and filter the air source entering the pneumatic surface and reduce the pressure to the surface to supply additional air source pressure, which is equivalent to the function of the power transformer in the circuit. The valve limit switch is a kind of on-site appearance for detecting the valve condition in the control system. It is used to output the opening or closing position of the pneumatic control valve with the signal of the switch value (contact), which is accepted by the controller or searched and sampled by the computer. After confirmation, the next procedure is performed.

This product can also be used as an air filter pressure reducer for interlocking protection of important valves and remote alarm indication in the self-system. The planning is light and small, and the device is convenient. Therefore, it is used together with pneumatic transmitters, pneumatic regulators, valve positioners and other product devices. If the air filter and the regulating valve are planned as a whole, they become two couplings. Proper air pressure control will definitely make the function reach the expectation. The air pressure control system is the core of the air pressure regulating valve. A series of problems exist in this aspect. The air pressure control requirements cannot reach the expected specifications, and the power for valve replacement is relatively low, which will fundamentally affect the water flow control function. Before air pressure regulation, it is necessary to have a full understanding of the urgency of the water area. If it is relatively stable, the low-pressure control concept should be selected at the moment. If the water flow is relatively turbulent, the high-pressure control concept should be selected. When the water flow is changed, it is necessary to change the air pressure in time to fundamentally reach the expected working effect. After the above description, I believe that we have a more comprehensive understanding of the importance of pneumatic control valve enterprise control. This kind of system will be upgraded in all aspects in the future, and the system will have stronger advantages after it is perfected.
       Pneumatic control valveCommon leakage problems, valve leakage pneumatic control valve due to improper stem length, stem length is too long, so that the stem up and down too short, resulting in valve core and seat clearance is not completely touch, resulting in valve leakage. Pneumatic control valve packing leakage Pneumatic control valve will be packed into the stuffing box, will apply axial pressure to the control valve. Due to the plastic deformation of the packing, radial pressure will occur, and the valve stem touches tightly, but the touch is uneven. During operation of the pneumatic control valve, the valve stem and the package will move axially. In high temperature and high pressure environment, due to high permeability, simple leakage. Pneumatic control valve spool and valve seat deformation leakage erosion and impact of pneumatic control valve, so that its deformation, with the passage of time, there will be a valve core and valve seat mismatch phenomenon, there is a gap between them, and because the gap is loose and leakage. If your pneumatic control valve leaks, you must first remove the above points and prescribe the right medicine.
The above is Wuxi Xinming automatic control valve industry to introduce the relevant content.
