Flexible pneumatic valve when using the matters needing attention

Flexible pneumatic valve is a kind of used to implement the circulation piping system or truncation and flow control components, have been widely used in many fields. Flexible pneumatic valve plate installed on the diameter of the pipe direction. In pneumatic valve pneumatic valve, cylindrical channels in the disc plate around the axis of rotation, rotation Angle for 0 ° ~ 90 °, rotate to 90 °, the pneumatic valve is fully open. The pneumatic valve average installation.
flexible pneumatic valve use notice:
1, the assembly check pneumatic pneumatic valve before no missing parts, each part model is correct, check the pneumatic valve body without sundry, non-blocking solenoid pneumatic valve and the muffler.
2, the pneumatic valve and cylinder are placed in the closed position.
3, will hit the pneumatic valve cylinder, ( The installation direction and pneumatic valve parallel or vertical) , see if the screw hole for again, won't have too big deviation, if you have a little deviation, cylinder block turning point, then tighten the screw.
4, after the installation, debugging of pneumatic pneumatic valve ( Under normal circumstances gas supply pressure is zero. 4 to 0. 6MPa） Debugging operation manual operation with electromagnetic air valve opening and closing ( The electromagnetic solenoid coil manual operation shall be effective after losing electricity And observe the flexible pneumatic valve opening and closing. If found in the process of the test and operation of pneumatic valve some difficulty in opening and closing process of the initial, after normal, you may need to dispatch cylinder stroke ( On both ends of the cylinder stroke adjusting screw to adjust a bit at the same time, the adjustment when the pneumatic valve must be running to the open position, and then dispatch air off again) Pneumatic valve opening and closing action, until smooth and closed without any leakage. Also it is important to note that the adjustable type silencer pneumatic valve opening and closing speed can be adjusted, but not too small, otherwise may cause pneumatic valve is not action.
5, have to send before installation should keep dry, not in open air.
6, pneumatic valves to check all the pipes before installation, make sure that the pipe welding slag and other foreign body.
7, flexible pneumatic valve, pneumatic valve body resistance is moderate, hand-operated pneumatic valve torque matching with the selected actuator torque.
8, flexible pneumatic valve connected with the flange specifications correctly, pipe flange to the clamp are in conformity with the pneumatic valve flange standard. It is recommended to use pneumatic valve is special flange, flat welding flange shall be used.
9, verify the flange welding, pneumatic valve welding flanges shall not be made after installation, so as not to burn rubber parts.
10, the pipe flange are going to have to pack good, and with pneumatic valve into the.
11 and install all flange bolts, with the hand tight and will confirm the pneumatic valve and flange has to then be careful opening and closing of the pneumatic valve, to ensure that the opening and closing flexible.
12, the pneumatic valve fully open, tighten bolts, using a wrench, in accordance with the diagonal order without washers, never will bolt screw tight, in case caused serious distortion of pneumatic valve laps, open-close torque is too big.
