Pneumatic control valve installation details and skills < / div >

pneumatic control valve is usually controlled by pneumatic actuators and pneumatic valve connection installation after the formation of the composite. Pneumatic control valve installation and debugging is very important, this article mainly introduces the pneumatic control valve installation details and skills:
A. The installation process should always comply with the pneumatic control valve installation instructions and pay attention to the point; B。 Pneumatic control valve working environment temperature in ( - 30 ~ + 60) Relative humidity is not more than 95% 95%, the relative humidity is not more than 95%; C。 Control the length of straight pipe before and after pneumatic valve position should have, not less than 10 times the pipe diameter ( 10 d) Pneumatic valve, in order to avoid the straight pipe is too short and affect the flow characteristic; D。 Between the pneumatic valve installation, read the instruction manual. Products described in this instruction manual before installation and when installation should pay attention to safety issues and preventive measures; E. Confirm the pipeline cleaning: tube of the foreign body can damage the pneumatic valve sealing surface or even hinder the pneumatic valve core, the ball or butterfly plate movement caused by the pneumatic valve cannot be closed properly. In order to reduce the possibility of danger happens, should be cleaned all the pipe before installation of pneumatic valve. Confirm having cleanup dirt, metal chips, welding slag, and other foreign matter. In addition, check the pipeline flange in order to ensure a smooth surface of the gasket. If there is a threaded end pneumatic valves, paint on the pipe pin the high-grade pipe sealant. Don't on female thread sealants, because on the female thread excess sealant will be packed into pneumatic valve body. Redundant sealant will result in the accumulation of pneumatic valve core card plug or dirt, pneumatic valve can't normal close; F。 We carefully check control pneumatic valve: before installation, check and remove all transportation stop, protective use plug or the lid on the surface of the gasket, check the pneumatic valve inside to ensure that there is no foreign body; H。 Pneumatic control valve should be installed in horizontal pipe runs with them up and down and the vertical pipe, typically under pneumatic valve to support, to ensure stable and reliable. For special occasions, it is necessary to control pneumatic valve installed on the vertical pipe, also should control pneumatic valve support ( Except for small diameter control pneumatic valve) 。 When installed, want to avoid to bring additional stress to the control of pneumatic valve) ； G。 To ensure that at the top and bottom of the pneumatic valve leave enough space so that at the time of inspection and maintenance easily remove the actuators or pneumatic valve core. For pneumatic valve flange connection, make sure the flange surface accurately aligned evenly so that the gasket surface contact. Later, in the flange of gently tighten bolts, the last in a staggered form and tighten the bolt. Pneumatic control valve should be installed in storage when using the matters needing attention: A. This pneumatic valve should be stored in dry room and must be blocked on both ends of the channel, are not allowed to be stacked tailings storage; B。 Long-term storage of pneumatic control valve should be checked regularly, remove dirt, in all the moving parts and processing surface should be coated with anti-rust oil, prevent rust; C。 This pneumatic valve should be installed in horizontal pipe runs with required vertical installation, pneumatic valve lever upwards; D。 Required by this arrow and the medium for installation.
fault phenomenon and reason of pneumatic control pneumatic valve, can suit the action to solve.
