No picture, no truth:o Compact the filler a bit more; if that doesn’t work, replace it with a new one. If it still doesn’t work, the problem becomes serious.
Check whether the packing gland is tight; if not, it needs to be replaced
Release pressure, remove the old packing, fill in new packing, and then tighten it again
Live loading is also a solution
Check whether the packing gland is tightened properly; if not, tighten it again. If there is still leakage, relieve the pressure and replace the packing; if that doesn’t work, replace the valve.
