Nitrogen release device : This device adopts an internal feedback structure, allowing the medium to directly enter the detection mechanism (2) through the valve cover. The medium generates a force on the detection element, which balances with the preload force of the preset spring (3). When the pressure inside the tank rises to the pressure set point of the nitrogen release device, the balance is disrupted, causing the valve core (1) to move up, opening the valve and releasing nitrogen to the outside. When the pressure inside the tank drops to the pressure set point of the nitrogen release device, the valve is closed due to the action of the preset spring force.
