Medium: ultrapure water
FRP nitrogen sealed water tanks are generally used in ultra-pure water systems, that is, nitrogen is filled on the water surface of the water tank to maintain a proper positive pressure in the tank and prevent the atmosphere from contacting the water surface in the tank. Generally used in mixed bed or EDI electrodeionization equipment after the need to set up a buffer tank, a nitrogen sealed water tank is used as the buffer tank. The nitrogen sealing device is composed of two parts: a quick relief valve and a micro-pressure regulating valve. The quick relief valve consists of a pressure controller and a single-seat shut-off valve.
