Newbie seeking help with valves
Thread Content
Hello, experts. Our company needs to evacuate the space between the tanks at a gas station; sometimes water is present in that space, which causes water to come out during the vacuuming process. Therefore, a valve is needed to prevent water from being pumped out. In other words, it is possible to evacuate air, and the water valve will close in that case. If you have any recommended manufacturers or valves, please let me know. Thank you.
Can I inject water? This way, the gas is expelled.
It's sufficient to install a gas-liquid separator between the tank interlayer and the valve. I’ve really never heard of a valve with a soda separation function before.
For something that’s only outdated but not truly ineffective, the valve is probably powerless to do anything
A gas-liquid separator can be installed at the inlet and outlet of a gas compressor for gas-liquid separation; I’m not sure whether this is feasible or not.
We need to look at this matter from the root. First, why is there water in the vacuum insulation layer? Once again, to what extent does the insulation effect of the vacuum layer with water affect the system? Is this process condition safe? What is most feared at present is the normalization of abnormal processes. Everyone on site treated the abnormal conditions as normal, and a series of failures in safety measures led to the accident. This is just my personal opinion; please don’t criticize if you don’t agree
Hello, I’m not able to specify the exact inconvenience. Under normal circumstances, there should be no water in a compartment that has already become vacuum-sealed. Some oil tank manufacturers do not produce products of high quality; over time, this can lead to leaks, and water will accumulate in the interlayer. The pump, which is designed to replenish the air, will then draw out that water. So, a device is installed at the exhaust port to prevent the liquid from being drawn out.
What is the purpose of evacuating air? If water gets in, doesn’t that mean there’s a problem with the sealing?
It involves adding a gas-water separator to the vacuum pump pipeline, which functions as a filter, but it affects the efficiency of the pump.
