Can a check valve be installed on the air pipe? 1. The air pipe pressure is 6 m; it enters the tank from the bottom. To prevent backflow, can a check valve be installed? Can such a low pressure open the check valve? What type of check valve should be chosen? Thank you! 2. One of the storage tanks is equipped with a liquid seal, with a height of 0.25 m. To prevent negative pressure from drawing air into the tank, the tank’s vent pipe is connected to the atmosphere; thus, when negative pressure occurs, air is drawn into the tank from the atmosphere. Can such a low pressure be sufficient to open the check valve? What type of check valve should be chosen? Thank you!
Second question: Just use a breathing valve suitable for storage tanks.
A breathing valve should be used. . . . . . . . . .
Personally, I think it can’t be used! ! ! ! ! ! ! ! !
But the manufacturers of acid mist absorbers all use check valves; please advise!
Answer to the first question: The air pipeline can be raised above the liquid level in the tank, up to the U-tube, so that it will not flow into the front part of the inverted U-tube.
A low-pressure drop check valve can be used, with a pressure drop of 0.15 kPa achievable
Sir, does such a check valve really exist? Could you recommend a manufacturer?
It must be there; I’m not really sure about the manufacturer – I’m only responsible for providing the data sheet
There are some things I don’t understand. Are there any diagrams or actual images?
