How to determine if there is internal leakage in a vaporization lockhopper valve?
Thread Content
The question is, which valve are you referring to?
The lockout valve should be equipped with a transmitter for measuring pressure or differential pressure; in the event of a leak, an alarm will be triggered for either the pressure or differential pressure, and this can be seen on the display
There are many types: pressure filling valves, pressure relief valves, flushing water valves, slag locking valves, and so on
1. When the coal powder lockhopper valve is closed, monitor the changes in lockhopper pressure. 2. Check whether the pressure relief pipeline of the slag lock hopper is hot; check the pressure with the valve closed, and see if there is any overflow in the flushing water tank
The temperature of the lockhopper: internal leakage in any of the valves can cause this temperature to rise gradually. This is usually visible on the computer, after which it is necessary to check whether the pipelines connected to those valves are hot, in order to determine which valve is leaking
Specifically speaking, there are several valves here
