  • 8.A gas pressure regulating box equipped with an overpressure cut-off valve, the cut-off pressure is set at 1.5 times the output pressure. The box body of the gas pressure regulating box can be made into ordinary type or thermal insulation (heating) type according to the temperament. For dry, water-free qualities (such as natural gas, etc.), you can choose a common box. For gas qualities that contain water and are greatly affected by temperature changes (such as artificial coal gas, liquefied petroleum gas, etc.), you must select an insulated box to ensure the normal gas supply of the pressure regulating system.

    The working principle of a gas pressure regulator involves a balance between the incoming gas pressure and the force exerted by a spring inside the device. When gas flows into the regulator, it pushes against the diaphragm, which is connected to the spring. As the pressure increases or decreases, the diaphragm moves, adjusting the valve’s opening to maintain the set pressure. This feedback loop ensures that the output pressure remains consistent, regardless of variations in the input pressure or flow rate.

    With the slowdown of my country's economic growth rate, my country's economic growth mode will change from the original extensive to intensive in the future. From the perspective of the valve industry, the future development direction of valves is energy saving, so the development prospect of gas pressure reducing valves is very good. The gas pressure reducing valve is generally a diaphragm structure, and its precision is relatively high. The gas pressure reducing valve uses the diaphragm to sense the change of the outlet pressure, and the pilot valve is opened and closed to drive the spool to adjust the size of the overflow area of ​​the throttle portion of the main valve, so as to realize the pressure reducing and regulating function. When the pressure, temperature and specifications allow, the gas pressure reducing valve can be used as a water pressure reducing valve.
