What are the signs if the upper and lower outlet valves of a glass plate level gauge become clogged? Is it the glass panel that gets full, or are there other signs?
The valve at the top is blocked, so the liquid level can’t rise; the blockage at the bottom causes an incorrect liquid level reading. Inspection completed
This usually involves closing the upstream and downstream valves, opening the vent, and then opening the upstream and downstream valves separately to determine which port is blocked.
If there is a blockage at the upper level, the display will change, but at a slower pace; if there is a blockage at the lower level, the display will not change.
The method to determine whether it is a false level is as mentioned on the second floor: regardless of whether the inlet or outlet is blocked, it is necessary to first confirm whether the current level is normal before making a judgment.
Lower valve plug in place; liquid level remains unchanged； When the upper valve is blocked, the change in liquid level becomes slower and slower, until no change occurs any more (an air lock is formed). During processing, the upper and lower valves can be closed separately, and the drain plug or valve can be opened to determine which valve is blocked, after which appropriate actions can be taken
The glass plate of the container in our unit is fitted, the upper discharge valve is blocked, and the glass plate level gauge shows it’s full.:o
What I would like to ask is, based on experience, can it be determined directly from the appearance? When the valve we mentioned gets blocked, the glass plate becomes full
Yeah, that’s right; it’s blocked at the bottom, so the liquid level won’t change. Open the drain valve to empty the material, and when it’s put back into use, the liquid level won’t be visible. If the upper outlet valve gets clogged, no gas phase can be discharged
