Introduces electric pneumatic valve and pneumatic adjust the installation technology of pneumatic valve

. Adhere to the correct installation technology should always comply with the pneumatic control valve ( Adjust the pneumatic valve manufacturer's installation instructions and pay attention to the point. Here the typical installation instructions as a simple conclusion. 。 Reading manuals between pneumatic valve installation, read the instruction manual. Products described in this instruction manual before installation and the installation should pay attention to safety issues and preventive measures. According to the guidelines in the manual to do help to ensure the installation simple and successful. 。 Verify that the foreign body in pipeline cleaning it might 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, leading to a pneumatic valve can't normally closed. 。 Check the pneumatic control valve ( Although regulating pneumatic valve pneumatic valve manufacturers will take some steps to prevent the transport damage, but this kind of damage or possible, and can be found and notified prior to installation. Do not install already know that has been damaged during transportation and storage of 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 body to ensure that there is no foreign body inside. 。 Most of the use of pipe connection good practice control pneumatic valve ( Adjust the pneumatic valve can be installed in any position, however, the most commonly used method is to vertically and is located in the upper part of the pneumatic valve actuator. If actuators level installation is needed, of the actuator is considered adding an extra vertical support. Shall ensure that such installation of pneumatic valve, fluid flow and the flow arrow or the direction indicated by the instruction manual. 。 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. Space distance can usually figure from the pneumatic valve manufacturer of dimension. 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. Properly tighten to avoid uneven gasket load, and helps to prevent leak, also helps to avoid the damage of the flange or even the possibility of cracks. When the connection flange and pneumatic valve flange material is different, pneumatic valve fluorine-butterfly butterfly this precaution is particularly important. Installed on the control of pneumatic valve ( Adjust the pneumatic valve upstream and downstream pressure pipe will help to check the flow or pressure drop. Will bring pressure pipe received from bend, reducing or hole diameter of straight pipe. This position can be due to fluid turbulent flow to minimize the inaccuracy. Use/or/inch ( - Mm tube put pressure on the actuator interface connected to the controller. Keep the short distance connection, and try to reduce the number of pipe fittings and elbow in order to reduce the system time lag. If the distance must be very long, you can in pneumatic control valve ( To adjust using a pneumatic valve positioner or supercharger.
