川消闭式泡沫水喷淋装置属于自动喷水和泡沫联用灭火系统的一种类型。在原有的湿式自动喷水灭火系统基础上增加了泡沫液供给装置，既可以喷水，又可以喷泡沫。由于泡沫与火焰相遇时能产生封闭效应、冷却效应、蒸汽效应等几种灭火效应的综合作用，故有良好的灭火效能。

The Sichuan fire extinguishing closed foam water sprinkler is a type of automatic sprinkler and foam combined fire extinguishing system. On the basis of the original wet automatic sprinkler system, a foam liquid supply device is added, which can spray both water and foam. When foam meets the flame, it can produce a combination of sealing effect, cooling effect, steam effect and other fire extinguishing effects, so it has good fire extinguishing efficiency.

该灭火系统采用水成膜灭火剂或成膜氟蛋白泡沫灭火剂，这种泡沫灭火剂在易燃液体的表面形成一种水成膜作为屏障隔绝空气，抑制易燃液体的表面气体蒸发，因而提高了灭火效果，并且可以防止火灾复燃，该灭火系统即节省了灭火用水，又提高了灭火效率，更适合用于水资源匮乏的地区。闭式泡沫-水喷淋灭火系统集中了湿式自动喷水灭火系统和泡沫灭火系统的优点，是更高的级别的自动灭火系统，可以完全代替普通的水喷淋自动灭火系统，其灭火效果更好。

This fire extinguishing system uses aqueous film-forming extinguishing agent or film-forming fluoroprotein foam extinguishing agent. This foam extinguishing agent forms an aqueous film-forming agent on the surface of flammable liquid as a barrier to isolate air and inhibit the evaporation of surface gas of flammable liquid, thus improving the fire extinguishing effect and preventing the re combustion of fire. This fire extinguishing system not only saves fire extinguishing water, but also improves the fire extinguishing efficiency, which is more suitable for areas where water resources are scarce. The closed foam water sprinkler system combines the advantages of the wet automatic sprinkler system and the foam fire extinguishing system. It is a higher level automatic fire extinguishing system and can completely replace the ordinary water sprinkler system, with better fire extinguishing effect.

在备用状态下，系统中各控制阀处于常态位置，并充满稳定的压力水(压力为0.14-1.2Mpa)，系统压力水通过泡沫罐供水管道14和供水控制阀13进入泡沫罐A的罐体和之间，内的水成膜泡沫液在囊外系统水压的作用下，通过泡沫液断流阀20压入泡沫液控制阀的进口端。同时，系统压力水通过控制管路进水球阀19、过滤器18、单向阀17、压力泄放阀、控制管路26进入泡沫液控制阀的控制腔，使泡沫液控制阀处于关闭状态，此时，系统处于备用状态。

In the standby state, each control valve in the system is in the normal position and filled with stable pressure water (pressure is 0.14-1.2Mpa). The system pressure water enters between the tank body of foam tank A through the water supply pipeline 14 of foam tank and the water supply control valve 13. Under the effect of the water pressure of the system outside the capsule, the water film forming foam liquid inside is pressed into the inlet end of the foam liquid control valve through the foam liquid cut-off valve 20. At the same time, the system pressure water enters the control chamber of the foam concentrate control valve through the control pipeline inlet ball valve 19, filter 18, one-way valve 17, pressure relief valve and control pipeline 26, so that the foam concentrate control valve is closed. At this time, the system is in standby state.
