Valve body hole leakage issue
Thread Content
The self-sealing high-pressure valves produced by Shanghai Yuangao – what is that small hole in the valve body? There is a leak at this hole on site; the pressure and volume of the leak are not very high, and soap water keeps bubbling when sprayed there. Could some colleague please advise me on how to handle this? ? Flammable gases do not allow welding
Haven’t seen it; I’ll ask the manufacturer for information
Whether it should be called YuanGao Valve Industry or YuanGao Valve Company is a question. Check the company’s website.
Oh, is there this difference too? Let me take a look to confirm
This should be an inspection hole for the valve seal; as for how to handle it, it is necessary to consult the manufacturer
Hello, this is the exhaust vent. A leak here indicates a problem with the seal in that area. Check whether the bolts securing the packing gland are tightened; if not, tighten them
This indicates that the self-sealing mechanism in this area has failed. Such valves prevent leaks at higher pressures; once a leak occurs, it remains, and simply tightening the nuts won’t resolve the issue.
Leakage has already occurred at the self-sealing ring in the middle section. That’s why there’s a leak here.
Flammable gas is leaking; be careful!
