What is the method of pneumatic valve in maintenance and installation?

When referring to the pneumatic control valve, it is believed that most people who have touched such components will not be unfamiliar. It is also known that such valves are generally connected to the regulating valve by a pneumatic actuator and installed and adjusted. And the formation of the combination. Of course, this installation and commissioning is very important. In the article, details of the installation of such control valves will be introduced.
The
Regardless of who installs it, it is necessary to observe the installation instructions and points of attention of the pneumatic regulating valve during installation; because its working ambient temperature can only be at minus 30°C to 60°C, and relative humidity cannot exceed 95%. The use of the environment; and the valve before and after the position must also have a straight section, the length can not be less than 10 times the diameter of the pipe, the valve straight pipe section is too short, making the flow characteristics.

When you install the valve, you must first read the instruction manual carefully. Because this manual mainly introduces such products and the safety precautions and precautions that must be taken into account before installation and during the process; of course, the pipeline must be cleaned and confirmed at the same time. Since foreign matter is easily present in the pipe, it can cause damage to the sealing surface of the valve or impede the movement of the valve plug, ball or disc, and ultimately make it impossible to close it properly. Therefore, to reduce the risk of a dangerous situation, it is necessary to install it before installation. It is necessary to clean the pipeline.

Also need to carefully check the pneumatic control valve, all the transport block, protective plug or gasket surface cover to check and clear it, but also the body of the valve there is no foreign body; to ensure that the valve on the upper and lower sides are sufficient The space, easy to check and maintain, easy to remove the actuator or valve core, such as the use of flanged valve body, to ensure that the flange surface is very accurate alignment, easy to gasket surface are very uniform contact. Then, after the flange is centered, it is necessary to gently tighten the bolt, and it is necessary to tighten the bolt in a staggered form.

When storing, installing, using, what should pay attention to the pneumatic regulating valve?

Pneumatic control valves like this should be placed in a dry room, and the two ends of the passage must be blocked and not stacked. For long-term storage of the regulating valve, check and remove dirt regularly. All kinds of moving parts and processing surfaces need to be coated with anti-rust oil to prevent regurgitation valve from rusting; when installing horizontal pipelines, they need to be installed vertically and the valve stems must be upwards; at the same time, they must be installed according to the media indicated by the arrows in the diagram.
