川消閉式泡沫水噴淋裝置屬于自動噴水和泡沫聯(lián)用滅火系統(tǒng)的一種類型。在原有的濕式自動噴水滅火系統(tǒng)基礎(chǔ)上增加了泡沫液供給裝置，既可以噴水，又可以噴泡沫。由于泡沫與火焰相遇時能產(chǎn)生封閉效應(yīng)、冷卻效應(yīng)、蒸汽效應(yīng)等幾種滅火效應(yīng)的綜合作用，故有良好的滅火效能。
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.
該滅火系統(tǒng)采用水成膜滅火劑或成膜氟蛋白泡沫滅火劑，這種泡沫滅火劑在易燃液體的表面形成一種水成膜作為屏障隔絕空氣，抑制易燃液體的表面氣體蒸發(fā)，因而提高了滅火效果，并且可以防止火災(zāi)復(fù)燃，該滅火系統(tǒng)即節(jié)省了滅火用水，又提高了滅火效率，更適合用于水資源匱乏的地區(qū)。閉式泡沫-水噴淋滅火系統(tǒng)集中了濕式自動噴水滅火系統(tǒng)和泡沫滅火系統(tǒng)的優(yōu)點，是更高的級別的自動滅火系統(tǒng)，可以完全代替普通的水噴淋自動滅火系統(tǒng)，其滅火效果更好。
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.
在備用狀態(tài)下，系統(tǒng)中各控制閥處于常態(tài)位置，并充滿穩(wěn)定的壓力水(壓力為0.14-1.2Mpa)，系統(tǒng)壓力水通過泡沫罐供水管道14和供水控制閥13進入泡沫罐A的罐體和之間，內(nèi)的水成膜泡沫液在囊外系統(tǒng)水壓的作用下，通過泡沫液斷流閥20壓入泡沫液控制閥的進口端。同時，系統(tǒng)壓力水通過控制管路進水球閥19、過濾器18、單向閥17、壓力泄放閥、控制管路26進入泡沫液控制閥的控制腔，使泡沫液控制閥處于關(guān)閉狀態(tài)，此時，系統(tǒng)處于備用狀態(tài)。
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.
