How to choose the gas valve in the official website of methane?
The regulator is a kind of equipment used in the gas transmission and distribution system to adjust the pressure, the solar energy, the safety of gas supply and the improvement of thermal efficiency. Usually used for centralized gas supply engineering, biogas high pressure adjusted to the rated pressure of appliance. At present, commonly used for RTZ-25H type marsh gas regulator, its structure as shown in figure 3.
Runfeng pipeline pressure regulator and imported gas storage leads connected to the air outlet and the gas appliance. The adjusting screw is used to control the spring; the tighter the screw clockwise, the higher the pressure of the air outlet; the film acts as a counterbalance to the pressure; the direct guide valve can control the size of the methane pressure.
from the gas storage gas by pressure regulator entrance throttling valve, the annular gap, the lower part of the film into space, methane pressure pressure and the lower film film the upper spring gradually reached equilibrium. Then according to the rated pressure to the stove before the gas appliance. When the inlet pressure is high, the valve is pushed up and the ring gap narrows to balance the upper and lower pressures of the film. On the contrary, when the inlet pressure drops, the valve drops and the ring gap widens, the film pressure is balanced up and down, and the gas supply is satisfied. Therefore, regardless of the inlet pressure change, the outlet pressure can be stabilized within a certain range, so that the flow rate to meet the use requirements.
