Is the bead in the valve of a glass tube level gauge effective?
Thread Content
The 300m3 storage tank is equipped with a glass tube level gauge. There is some concern regarding the risk of material leakage in case the glass tube breaks. However, in such a scenario, a ball inside the valve of the glass tube level gauge acts as a check valve; when there is significant leakage of material, this ball automatically presses against the inside of the valve, preventing the material from leaking out. In this way, large amounts of material will not leak due to the breakage of the glass tube. It’s not clear whether this check ball actually works effectively in practice I hope someone experienced can give me some advice. Thank you!
If it’s just the glass tube that cracks, then there should be no problem. But if the entire glass tube breaks, then those glass beads won’t function either :shutup:
In storage tanks equipped with glass tube level gauges, the check ball plays a certain role in practice; the more significant the pressure difference, the more pronounced the check function is.
