Install the pneumatic regulating pneumatic valve should pay attention to what issues?

when installing adjusting pneumatic valve should pay special attention to the following:
( Regulating pneumatic valve should be installed in horizontal pipe runs vertically, in special cases need level and tilt when installation, usually to add support.
( When adjusting the nominal diameter of pneumatic valve and pipe diameter is not at the same time, should be equipped with reducing joint to connect.
( Installation site should have good environmental conditions and environmental temperature should be in - ~ ℃.
( Try to avoid installed in places that have requirements of seismic source, otherwise the necessary shockproof reinforcement measures should be taken.
( When installation, must make the arrow on the pneumatic valve or flange pointing in the direction of medium.
( Before installation, it is necessary to carefully remove the pipe welding slag and other sundry; After the installation, should make the pneumatic valve core is in the biggest opening, and the pipeline and regulating pneumatic valve cleaning again, in case of sundry jam and damage the throttling.
( Pneumatic control valve should be installed in the position of easy to maintain, repair.
( Pneumatic valve before the straight pipe should be as long as possible.
( Outlet piping applications - pipe diameters of straight pipe.
( In order to ensure that adjust the pneumatic valve and regulating system failure does not affect the production and safety accidents occur, are generally need to install the bypass and by-pass pneumatic valve. Before and after regulating pneumatic valve should be installed by the pneumatic valve, for high temperature and high pressure, easy to cold, viscous medium, also install pneumatic valve guide tube. Bypass in regulating pneumatic valve pneumatic valve cannot be installed directly above, in order to avoid the bypass pneumatic valve leakage of corrosive medium to adjust the pneumatic valve.
