Installation requirements
Before installing the valve, carefully check whether the model and specification of the valve used are consistent with the design.
Check whether the valve can be applied under the required conditions according to the model of the valve and the factory manual.
When the valve is hoisted, the rope should be tied to the flange connection between the valve body and the valve cover, and should not be tied to the handwheel or valve stem, so as not to damage the valve stem and the handwheel.
When installing the valve on the horizontal pipeline, the valve stem should be vertically upward, and the valve stem should not be installed downward.
When installing the valve, it is not allowed to use the forced connection method of pulling and pulling hard, so as to avoid damage due to uneven force.
The rising stem gate valve should not be installed in the underground damp place, so as to avoid the valve stem from rusting.
Assembly requirements
Cleaned parts must be kept sealed for installation.
The requirements for the installation process are as follows:
The installation workshop must be kept clean, or a temporary clean area should be built, such as using newly purchased color strips or plastic films to prevent dust from entering during the installation process.
Assembly workers must wear clean cotton work clothes, cotton caps, no hair leakage, clean shoes, plastic gloves, and degreased hands.
Assembly tools must be degreased and cleaned before assembly.
