泡沫比例混合器是向泡沫產生設備和噴射設備提供混合液的設備，它與泡沫消防車上的消防泵或固定式消防泵配套使用，向泡沫滅火器設備輸送混合液。下面
川消小編為您講解下該產品的使用。
Foam proportioner is a device that provides mixed liquid to foam generating equipment and spraying equipment. It is used together with the fire pump or fixed fire pump on foam fire truck to deliver mixed liquid to foam extinguisher equipment. Now let's talk about the use of this product.
該比例混合器使用于低倍泡沫滅火系統，與消防泡沫炮、空氣泡沫槍、空氣泡產生器、空氣泡沫鉤管和液下噴射空氣泡沫產生器等配用。泡沫液一般配用3%型和6%型的低倍數蛋白泡沫滅火劑。
This proportioner is used in the low magnification foam fire extinguishing system, and is matched with the fire foam monitor, air foam gun, air bubble generator, air foam hook pipe, and underwater jet air foam generator. Foam liquid is generally equipped with 3% and 6% low expansion protein foam extinguishing agent.
泡沫比例混合器安裝在水泵上，與水泵相配用，根據配用泡沫噴射設備的泡沫混合液量的要求，按比例吸取泡沫液，并送水泵進水管中使之與水混合形成泡沫混合液的消防設備。
The foam proportioner is installed on the water pump and matched with the water pump. According to the requirements of the foam mixture volume of the foam spraying equipment, the foam liquid is drawn proportionally and sent to the fire fighting equipment of the water pump inlet pipe to mix it with water to form foam mixture.
1、混合器由調節手柄、指示牌、調節閥、混合室及擴散管等構成。
1. The mixer is composed of regulating handle, indicator, regulating valve, mixing chamber, diffusion tube, etc.
2、混合器指示牌上標有不同的流量指數，該指數與泡沫噴射設備的混合液量值對應。如：將調節手柄指向“4”數值時,混合器可滿足額定流量為4L/s的噴射泡沫設備所需泡沫混合液的混合比，其余以此類推。混合器均適合配用6%泡沫液。
2. Different flow indexes are marked on the indicator board of the mixer, which correspond to the volume of mixed liquid of foam injection equipment. For example, when the regulating handle is pointed to the "4" value, the mixer can meet the mixing ratio of foam mixture required by the foam injection equipment with the rated flow of 4L/s, and so on. All mixers are suitable for 6% foam liquid.
3、混合器應安裝在水泵附近,與水泵的進、出水管相連接?；旌掀鞒隹趬毫σ?0.03MPa,否則將影響混合器吸取泡沫液性能。
3. The mixer shall be installed near the water pump and connected with the water inlet and outlet pipes of the water pump. The outlet pressure of the mixer shall be less than 0.03MPa, otherwise the performance of the mixer to absorb foam liquid will be affected.
4、混合器進口壓力在0.6—1.4MPa范圍內,吸取泡沫液量在某一擋中基本不變。而產生和噴射泡沫設備在不同壓力下其混合液發生變化時,其混合比將發生變化。因此要適當調整和控制產生和噴射泡沫設備的壓力,使其壓力不能太高或太低,以便保證混合比在6～7％。
4. The inlet pressure of the mixer is within the range of 0.6-1.4MPa, and the amount of foam liquid absorbed is basically unchanged at a certain gear. When the mixture of foam generating and spraying equipment changes under different pressures, the mixing ratio will change. Therefore, the pressure of foam generating and spraying equipment shall be properly adjusted and controlled to ensure that the pressure is not too high or too low, so as to ensure the mixing ratio is 6-7%.
5、混合器適用6%型低倍數蛋白泡沫滅火劑。
5. The mixer is suitable for 6% type low expansion protein foam extinguishing agent.
該比例混合器工作原理是：
The working principle of the proportioner is:
當水泵壓力以很高的速度從噴嘴噴出進入混合室時，由于射流質點的橫向紊動擴散作用，將泡沫液吸入管內的空氣帶走，管內形成真空，泡沫液被吸入。兩股流體在擴散管前喉管內混合并進行能量交換，水流速度減小，被吸入液體的速度增加，在喉管出口處二者趨近一致，壓力逐漸增加。混合液通過擴散管后，大部分動能轉換為壓力能，使壓力進一步提高，后進入水泵再次在泵內充分混合并輸出。
When the water pump pressure is ejected from the nozzle into the mixing chamber at a very high speed, the air in the foam liquid suction pipe is taken away due to the transverse turbulent diffusion of the jet particle, and a vacuum is formed in the pipe, and the foam liquid is sucked in. The two streams of fluid mix and exchange energy in the throat before the diffuser. The water flow velocity decreases, and the speed of the liquid sucked in increases. At the throat outlet, the two tend to be the same, and the pressure gradually increases. After the mixed liquid passes through the diffusion tube, most of the kinetic energy is converted into pressure energy to further increase the pressure, and then the inlet pump is fully mixed and output in the pump again.
此外應經常保持消防泡沫炮的完整和清潔，每使用過一次后應沖洗干凈。同時應注意檢查各聯接件是否緊固，密封圈是否缺損，操縱桿和手動調節轉動件是否靈活，以保證消防泡沫炮應急使用時性能可靠。更多相關內容就來我們網站

In addition, keep the fire foam monitor complete and clean, and wash it after each use. At the same time, attention should be paid to checking whether the connecting pieces are fastened, whether the sealing ring is damaged, and whether the operating lever and the manually adjusted rotating parts are flexible to ensure the reliable performance of the fire foam monitor in emergency use.
