Adjustment of the pneumatic valve applicable occasions and application conditions

as a result of the movement of pneumatic valve pneumatic butterfly valve plate with polished, so most of the butterfly pneumatic valve can be used in the medium with suspended solids, based on the strength of the seal can also be used for powder and granular media.
adjustment structure of the pneumatic valve length and smaller overall height, opening and closing speed, when fully open, with a small fluid resistance, when open to around ° to °, and can perform a sensitive flow control, hong feng butterfly structure principle of the pneumatic valve is best suited for production of large diameter pneumatic valves.
think hong feng pneumatic valve under the condition of the following conditions, adjustment of pneumatic valve is used in the recommended:
(1) for throttling and adjusting control flow;
(2) slurry medium and medium containing solid particles;
3. Requiring shorter pneumatic valve structure;
(4) for opening and closing speed occasions;
5) differential smaller places.
in two position adjustment, reducing channel, low noise, have spirit of hole and gasification phenomenon, a small amount of leakage into the atmosphere, with abrasive medium, can choose butterfly pneumatic valve.
under the condition of the special working condition of throttling or seal strict, or wear, low temperature, Cryogenic use pneumatic valve adjustment, such as operating conditions require special design of triple eccentric metal sealing with conditioning or double eccentric butterfly pneumatic valve.
hong feng signal butterfly pneumatic valve driven by worm gear and worm drive gear shaft and butterfly plate rotating realize opening and closing and traffic control. Rotate the worm gear and worm drive gear handwheel, make the butterfly plate to achieve the purpose of opening and closing and regulating flow, the handwheel clockwise for pneumatic valve shut off.

use the device in accordance with the requirements of electric control the conductor of the cable connects to the corresponding terminal, and imported sealed cable, the cable is fixed at the same time, in order to prevent damage of external force affects the cable wiring. When the pneumatic valve 'seated' position, the following close to the CAM clockwise or counterclockwise rotation in open CAM, butterfly pneumatic valve in the pipe clamp, pay attention to whether the relay of uniform and reliable. Butterfly pneumatic valve is installed, the pipeline strength test, pneumatic valve plate must be in an open position. Butterfly pneumatic valve is installed, should periodically check, the check of the main projects are as follows: adjustment of pneumatic valve pneumatic seat and type O sealing ring damage. Pneumatic valve plate seal face seal performance. Butterfly pneumatic valve repair after assembly, opening and closing rotates can not have jam phenomenon. Butterfly pneumatic valve repair after assembly, should be sealed performance test as required.
