Nitrogen sealing device (nitrogen sealed valve) is operational self-reliance by ZZDG type command type pressure regulator (here for nitrogen valve) and type ZZDX self-reliance decay pressure regulator (hereinafter referred to as nitrogen discharge valve) of two most. When the tank pressure increases more than the set value for nitrogen valve closed, nitrogen discharge valve open (roof have a breather valve, or the breather valve failure won't open), the tank excess pressure relief. In the storage tank pressure is lower, nitrogen discharge valve closed, open valve for nitrogen, the nitrogen injection to the tank. For nitrogen valve pressure below 1.0 Mpa, best before the pressure is high, it can be installed in front of the valve for nitrogen a ZZYP type pressure regulator reduced the pressure to themselves. Below 1.0 Mpa, in order to improve reliability and use effect.
Nitrogen sealing device (nitrogen sealed valve) for (drain) nitrogen pressure setting is convenient, may be done under the condition of continuous production. Within the scope of the set pressure, such as from 100 mm H20 H20 need to adjust to 50 mm, may by adjusting for nitrogen at the top of the valve adjusting screw, change the spring force, needs a new set of process could be achieved with value. Nitrogen discharge valve adjustment is also in the same way. Breathing valve set point adjustment: After the above Settings to adjust, in order to avoid breathing valve opening and closing is frequent, the respiration valve value should be greater than the pressure setting.
