4.結(jié)構(gòu)和工作原理
PY系列半固定式（輕便式）泡沫滅火裝置（見(jiàn)下圖），由管線(xiàn)式比例混合器、泡沫液儲(chǔ)液箱、吸液管等部分組成。當(dāng)消防泵的壓力水供水管道進(jìn)入比例混合器時(shí)，形成負(fù)壓區(qū)，可將儲(chǔ)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。經(jīng)擴(kuò)散管道送出進(jìn)行滅火。
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
