Pneumatic pneumatic valve installation methods and techniques in detail

Pneumatic pneumatic valve before installation should do the following steps, the operation of the pneumatic pneumatic valve was able to make better work.



1, a visual inspection must be conducted before installation, pneumatic valve nameplate shall comply with the current national standard 'general pneumatic valve symbol' GB12220 rules. For the working pressure is greater than 1. 0 mpa and pneumatic valve with the function of cutting on ZhuGanGuan, strength and strict performance test should be done before the installation, qualified rear must use.

2, before installation, check the pneumatic pneumatic valve no missing parts, each part model is correct, check the pneumatic valve body without sundry, solenoid pneumatic valve and the muffler internal nonblocking

3, the pneumatic valve and cylinder are placed in the closed position.

4, strength test, the test pressure for the nominal pressure of 1. 5 times, duration of not less than 5 min, pneumatic valve shell, packing should be no leakage as qualified.

5, 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.

6, after the installation and debugging of pneumatic pneumatic valve ( Under normal circumstances gas supply pressure is zero. 4 to 0. 7MPa） Debugging operation manual operation with electromagnetic air valve opening and closing ( The electromagnetic solenoid coil manual operation shall be effective after losing electricity , observation of pneumatic 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.



7, have hair before installation should keep dry, not in open air.

8, pneumatic valves to check all the pipes before installation, make sure that the pipe welding slag and other foreign body.

9 manual type, pneumatic valve, pneumatic valve body resistance is moderate, pneumatic valve torque matching with the selected actuator torque.

10, pneumatic valve connected with the flange specifications correctly, pneumatic valve flange pipe flange to the clamp and consistent standards. It is recommended to use pneumatic valve is special flange, flat welding flange shall be used.

11, verify the flange welding, pneumatic valve welding flanges shall not be made after installation, so as not to burn rubber parts.

12, in the pipe flange are going to have to pack good, and with pneumatic valve into the.

13 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.

14, 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.

15, when installation, pneumatic disc to stop in the closed position. Open position should be according to the board to determine the Angle of rotation. With bypass air moving valve, pneumatic valve, open the ventilation should be taken before opening valve. Pneumatic pneumatic valve shall be installed according to the manufacturer's installation instructions and big weight of pneumatic valve, should set up a solid foundation. Installation position, height, import and export direction must comply with the design requirements, pay attention to the direction of the medium flow shall conform to the direction of the arrow by pneumatic valve body, the connection should be firmly connected
