Globe Valve Operation
Not only should we learn to install and maintain the globe valve, but also we must be able to operate it.
When opening and closing the globe valve, the force should be steady without impact. When the globe valve is fully opened, the handwheel should be turned upside down to tighten the threads to avoid loosening and damage. When the pipeline is first used, there is a lot of internal dirt. You can open the globe valve slightly, use the high-speed flow of the medium to wash it away, and then close it gently (not fast or violently to prevent residual impurities from trapping the sealing surface). Turn it on again, repeat this many times, flush out the dirt, and then put it into normal work.
If the globe valve is opening for a long time, there may be dirt on the sealing surface. When it is closed, use the above method to flush it, and then formally close it tightly. If the handwheel and handle are damaged or lost, they should be provided immediately, and can not be replaced with a flexible wrench, so as to avoid damage to the valve stem and failure of opening and closing, which may cause accidents in production.
Some medium cools down after the globe valve is closed, causing the valve to shrink. The operator should close it again at an appropriate time so that there are no crevices on the sealing surface. Otherwise, the medium will flow through the crevices at high speed and it will easily erode the seal.
During operation, if the operation is found to be too laborious, the reason should be analyzed. If the packing is too tight, it can be properly loosened. If the valve stem is skewed, personnel should be notified to repair it. In some globe valves, when closed, the closing part is heated and expanded, which makes it difficult to open; if it must be opened at this time, the valve cover can be loosened half a turn to one turn to eliminate the stress on the valve stem, and then move the handwheel.
