Structure of pneumatic pressure control valve < / div >

pneumatic pressure control valve is a kind of pressure balance type pneumatic control valve, the structure of single seat, sleeve, with many spring pneumatic diaphragm actuator, actuator low height, light weight, simple equipment. Pneumatic pressure pneumatic valve pneumatic control valve core with cage sleeve pneumatic valve core, the air pressure change of pneumatic valve core linear displacement, the automatic control of pneumatic control valve opening, the pressure of the fluid inside the pipeline continuous adjustment.
analysis of the structure principle of the pneumatic pressure control valve is as follows:
pneumatic pressure control valve because they do not need other foreign energy such as electricity, gas, only rely on media's own energy to drive, both energy saving and environmental protection, easy to use, after the installation is set pressure value can be put into automatic operation, so the control accuracy is not high, and the lack of electricity, gas, has been more and more widely used. But in the process of pneumatic pressure control pneumatic valve use, must pay attention to the particularity of selection, otherwise easy to cause accident. In use process, must pay attention to the use of selection and installation environment, therefore, detailed understanding of the working principle and structure of the pneumatic valve pneumatic pressure control is very important.
