4.结构和工作原理
PY系列半固定式（轻便式）泡沫灭火装置（见下图），由管线式比例混合器、泡沫液储液箱、吸液管等部分组成。当消防泵的压力水供水管道进入比例混合器时，形成负压区，可将储液箱里的泡沫液吸入比例混合器，按比例（3或6）形成混合液。经扩散管道送出进行灭火。
4. The structure and working principle
PY series of semi-fixed (portable-type) foam extinguishing plant (see below) consists of thepipeline foam proportioner, foam liquid storage tank, pipettes and other parts. When the fire pump pressure water supply pipe into the proportioner, form a negative pressure zone and the foam liquid in the liquid storage tank can be inhaled proportioner, in p
