Problems with nitrogen seal setting of fixed roof tanks
Thread Content
Excuse me: Is this how the nitrogen seal of the fixed-top tank is set up? ——The nitrogen pipeline is led from the outer pipe of the nitrogen device in the factory to the tank area, and is connected to the nitrogen seal on the tank through a valve. The valve is opened to transport nitrogen when needed, and the valve is closed when not needed. Or - there may be a pressure display, the valve is closed when the pressure is reached, or the pressure is used to control the regulating valve on the nitrogen pipeline to maintain the pressure in the tank. I don’t know if this is right, but I just heard about nitrogen sealing. Willing to ask experts for guidance.
There is a pressure gauge, orifice plate or self-operated control valve, the nitrogen is always open, and an exhalation valve is installed on the top of the storage tank to maintain the pressure.
I agree with what was said on the second floor. It is very simple. Set up a pressure regulating valve with automatic pressure control. An orifice plate is set in front of the valve and set at about 3KPA. When the pressure is low, nitrogen is automatically supplied. When the pressure is high, the valve is closed. There is also a breathing valve to prevent the pressure from being too high.
After setting up according to the instructions on the third floor, do I still need to set up the nitrogen water sealing tank?
The third floor explains the problem of setting up nitrogen sealing pressure control. It has nothing to do with whether nitrogen sealing is set up or not.
