Installation method of electric control valve

更新時(shí)間:2018.07.20
Installation of electric regulating valve:
Generally, the pipeline installing the regulating valve should not be too high off the ground or floor. When the height of the pipeline is greater than 2m, the platform should be set as far as possible to facilitate handwheel operation and maintenance.
Regulator belongs to the field instruments for environmental temperature should be in 25 ~ 60 ℃, relative humidity 95% or less. If it is installed in open air or high temperature, waterproof and cooling measures should be adopted. Stay away from the source or add vibration protection where there is a source.
In order to enable the control valve to continue the production process in case of failure or maintenance, the control valve shall add bypass pipeline.
The regulating valve should be installed vertically in general, and can be tilted in special cases. For example, when the tilt Angle is large or the valve itself is too heavy, the protection of supporting parts should be added to the valve.
Before installing the regulating valve, the pipeline shall be cleaned to remove dirt and welding slag. After installation, to ensure that no impurities remain in the valve body, the valve should be cleaned again, that is, all valves should be opened when entering the medium to avoid impurities sticking. After using the handwheel mechanism, the original neutral position should be restored.
