The issue of leak detection for equipment valves
Thread Content
As the title suggests, cone valves are used for sealing the coal hopper in fixed-bed Ruhr-type furnaces. How can the sealing performance under such operating conditions be evaluated? For example, how can the leakage rate under airtight conditions be evaluated more reasonably?
We usually check for airtightness by checking the pressure and listening for sounds. In the event of a leak when it is airtight, replace the valve head directly.
Is there a standard for measuring pressure changes? The key question is whether this valve can remain leak-free under these operating conditions?
