泡沫噴頭和泡沫/水兩用噴頭是產生和噴射空氣泡沫的滅火部件，主要用于低倍數泡沫噴淋系統。下面
川消小編來講講泡沫噴頭工作原理及安裝要點。
Foam sprinklers and foam/water dual purpose sprinklers are professional fire extinguishing components that generate and spray air foam, mainly used for low expansion foam spray systems. Now let's talk about the working principle and installation points of foam nozzle.
1.工作原理
1. Working principle
空氣泡沫噴頭與固定式泡沫滅火系統配套使用，泡沫噴頭所需泡沫混合液由泡沫比例混合裝置提供，適用于3％或8％型低倍數泡沫混合液。
The air foam nozzle is used together with the fixed foam extinguishing system. The foam mixture required by the foam nozzle is provided by the foam proportioning device, and is suitable for 3% or 8% low expansion foam mixture.
當泡沫混合液經由管道輸送泡沫噴頭，在噴頭內部混合液與其吸入的空氣充分混合，形成擴散的霧化射流，觸及噴頭內壁、泡沫擊散器等形成渦流，并因此而發泡，成為低倍數泡沫，再經傘型擋水盤，在其周圍的保護面積內均勻的噴灑泡沫，覆蓋在燃燒物體的表面，窒息、冷卻從而撲滅火災。
When the foam mixture is transported to the foam nozzle through the pipeline, the mixture inside the nozzle is fully mixed with the air it inhales to form a diffused atomized jet, which touches the inner wall of the nozzle, the foam diffuser, etc. to form a vortex, and thus foams to form a low expansion foam. Then, through the umbrella shaped water deflector, evenly spray foam on the surrounding protected area to cover the surface of the burning object, asphyxiate and cool to extinguish the fire.
2.安裝
2. Installation
（1）下垂式泡沫噴頭安裝時傘形擋水盤朝下，直立式泡沫噴頭安裝時傘形擋水盤朝上。
(1) The umbrella shaped water deflector shall be downward when installing the sagging foam sprinkler, and upward when installing the vertical foam sprinkler.
（2）安裝泡沫噴頭的管道進口孔徑不得小于噴頭進口尺寸，根據工程需要，采取防止異物堵塞噴頭的措施。
(2) The inlet diameter of the pipe where foam sprinklers are installed shall not be less than the inlet size of the sprinklers. According to the needs of the project, measures shall be taken to prevent foreign matters from blocking the sprinklers.
（3）噴頭應安裝在不會受到機械損傷的地方，在安裝前應確認噴頭規格型號、連接尺寸等參數符合要求。
(3) The nozzle shall be installed at a place free from mechanical damage. Before installation, it shall be confirmed that the specifications, models, connection dimensions and other parameters of the nozzle meet the requirements.
This is the end of the question about the working principle and installation points of the foam nozzle explained by Chuanxiao Xiaobian. You can use this as reference information. More relevant information will come to our website http://www.xintli.net Consult!
