泡沫消火栓是泡沫滅火系統(tǒng)中的重要裝置之一,特別適用于大面積有火災(zāi)危險的易燃液體和可燃液體的產(chǎn)生,貯存和使用場所.那么它的組成機構(gòu)是什么呢？來聽聽消防箱廠家的一番介紹: Foam hydrant is one of the most important devices in foam extinguishing system. It is especially suitable for the production, storage and use of flammable liquids and flammable liquids. To listen to the fire box manufacturer's introduction: 泡沫消火栓主要由法蘭、筒體、球閥、內(nèi)接、消防管牙及端蓋組成.地上式泡沫消火栓根據(jù)法蘭接口分為PSS80-65X2、PSS100-65X2、PSS150-65X2三種型號.泡沫消火栓額定工作壓力為1.6MPa范圍內(nèi). The foam hydrant is mainly composed of flanges, cylinders, ball valves, internal connection, fire hoses and end covers. The upper floor foam hydrants are divided into three types according to flange interfaces: PSS80-65X2, PSS100-65X2 and PSS150-65X2. The rated working pressure of foam hydrant is within 1.6MPa. 泡沫消火栓適合裝備于石油化工企業(yè)、煉油廠、貯油罐區(qū)、飛機庫等重要場所.安裝在泡沫混合液管錢上向泡沫噴射設(shè)備供給泡沫混合液的一種專用消防設(shè)備. Foam hydrant is suitable for oil and chemical enterprises, refineries, oil storage tanks, hangar and other important sites. It is a special fire equipment installed on foam mixing liquid pipe to supply foam mixing liquid to foam spray equipment. 泡沫消火栓箱主要由比例混合器、泡沫液罐、軟管卷盤(消防水帶)、滴水閥(低壓泄漏閥)、液面計、進(jìn)氣閥、進(jìn)水(排污)閥等構(gòu)成. Foam hydrant box is mainly composed of proportioning mixer, foam liquid tank, hose reel (fire hose), drip valve (low pressure leakage valve), liquid level gauge, intake valve, water inlet (drain) valve and so on. 泡沫消火栓箱在滅火時當(dāng)有不低于0.35MPa壓力的水以很高的速度流過泡沫消火栓箱的管道及管線比例混合器時,由于射流質(zhì)點的橫向移動的擴散作用,比例混合器的室內(nèi)形成真空(負(fù)壓),于是泡沫液儲罐內(nèi)的泡沫液在大氣的壓力作用下通過吸液管進(jìn)入混合器,與壓力水混合,最終達(dá)到一定比例的混合液.當(dāng)具有一定壓力的混合液流到時使泡沫混合液發(fā)泡.從而達(dá)到泡沫滅火的效果.該裝置廣泛用于隧道 油庫、化工廠、機庫、油田、燃油鍋爐、地下車庫等場所. Foam fire hydrant box at the time of the fire when there is no less than 0.35MPa pressure in water pipe velocity through the foam fire hydrant box high and pipeline proportioner, due to diffusion of the lateral movement of the particle jet, proportioner indoor vacuum (negative pressure), and the foam tank inside the foam liquid in atmospheric pressure through the pipette into the mixer, mixing water and pressure, the final mixture at a certain ratio. When the mixed fluid with certain pressure and flow the foam mixture foam. So as to achieve the foam extinguishing effect. The device is widely used in tunnel depot, chemical plants, oil and fuel boiler, hangar, underground garage and other places.
