PHYM系列壓力式比例混合裝置由壓力罐、膠囊、比例混合器、安全閥、排氣閥、壓力表、單向閥及各類控制閥及管道組成。由泵供給壓力水，將泡沫液按一定比例置換出來后與壓力水混合成泡沫混合液。由于膠囊將泡沫液與水隔開，泡沫液一次沒用完，下次可以繼續(xù)使用且混合精度穩(wěn)定、可靠。

Foam bladder tank is used for providing foam solution for foam system. It mainly consists of pressure tank, rubber bladder, proportioner, control valves, and pipelines. Pressurized water is needed to swap out foam concentrate from bladder in the tank as a certain proportion. Foam concentrate then mix with pressurized water and become foam solution. There is feed inlet to refill or change foam concentrate for the tank.
