Natural gas generating units with the engine load changes, the mixer by governor control and conditioning, to supply or mixed gas, adapt to the engine power demand. The mixer mixer and air pressure opening to control the fuel gas of the cone valve.
When the pressure of the fuel gas enters the mixer to the fixed value, can make the air and gas mixture comprising the volume ratio unchanged, the air-fuel ratio does not change because of load is not the same. This is of vital importance to the engine working conditions.
Air enters the mixer, mixer horizontal tube into the gas from the mixer in a two cone valve. Two conical valve installed in the horizontal pipe at both ends of the diaphragm assembly, a spring sheet.
When the mixer is not in operation, the side wall at both ends of the diaphragm in the spring under the effect of the mixer body and clinging, femoral artery and the conical valve block two transverse pipe mouth and hindering the gas after.
