Where Is The Valve Handwheel Installed

The valve handwheel should be located in a place that is easy to access, easy to operate and maintain. The valves on the rows of pipelines (such as the pipelines entering and exiting the device) should be arranged centrally, and consideration should be given to operating platforms and ladders. The valves on the pipelines should be arranged in parallel. The clear distance between the handwheels should not be less than 10Qmm. In order to reduce the distance between the pipes, the valves can be staggered. The installation position of the frequently operated valve handwheel should be easy to operate, and the appropriate installation height is 1.2m from the operating surface. When the height of the center of the valve handwheel exceeds the operation surface by 2m, a platform for centralizedly arranged valve groups or frequently operated individual valves and valves should be provided, and appropriate measures should be taken for individual valves that are operated infrequently (such as chain wheels, extension Poles, moving platforms, moving ladders, etc.). The chain of the sprocket should not impede traffic. Valves on pipelines and equipment for hazardous media must not be installed within the height of a person's head to avoid injury to the person's head or direct injury to the person's face when the valve leaks.
