The adjusting mechanism of the main work

in the process of production, in order to make the medium parameters such as pressure, flow conforms to the requirement of technological process, need to install the regulator to adjust the above parameters. The main working principle of regulating mechanism, it is by changing the pneumatic valve and pneumatic valve and pneumatic pneumatic valve seat valve between the circulation area, achieve the purpose of regulating the parameters. Belong to this type of pneumatic valves are collectively referred to as the pneumatic control valve, which is divided into depending on the medium power driven itself is called the displacement type pneumatic control valve, such as reduced pressure pneumatic valve, pneumatic valve regulated all leading up to driving, Such as electricity, compressed air and fluid power) Called him drive type pneumatic control valve, such as electric regulating pneumatic valve, pneumatic regulating pneumatic valve and hydraulic pneumatic valve, etc.
