  天然气发电机组随发念头负荷的改变,混合器受调速器的操控与调理,以增减混合气的供应量,适应发念头功率的需求。该混合器使用混合器前后的空气压差来操控燃料气锥形阀的开度。

  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.

  当进入混合器的燃料气压力坚持定值时,可使所构成的混合气中空气与燃气的体积比不变,使空燃比不因负荷不一样而变。这对发念头的工况至关重要。

  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.

  空气进入混合器,可燃气从混合器内一根两头有锥形阀的横管进入混合器。该横管两端的两个锥形阀装在膜片总成中,模片上有绷簧。

  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.

  当混合器不作业时,两头的膜片在绷簧的效果下与混合器体的侧壁紧贴,并股动上述锥形阀堵住横管的两头口而阻碍可燃气的经过。

  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.
