低倍数泡沫灭火系统的内外浮顶指代什么？实际上这个操作在使用中还是很重要的，下面川消小编就来为您讲讲吧。

What does the internal and external floating roof of low expansion foam fire extinguishing system mean? In fact, this operation is very important in use. Let's talk about it for you.

1、非水溶性泡沫液储罐液下半液下喷射，起泡沫混合液供给强度不应小于5L/(min.m)，连续供给不应小于40min。

1. The water-insoluble foam liquid is sprayed under the liquid and half liquid in the storage tank. The supply intensity of foam mixed liquid shall not be less than 5L / (min.m), and the continuous supply shall not be less than 40min.

2、泡沫进入甲乙液体的速度不应大于3m/s；泡沫进入丙类液体速度不应大于6m/s，对于水溶性液体储罐来说，应设置泡沫缓冲装置。

2. The velocity of foam entering the liquid of Party A and Party B shall not be greater than 3m / S; The velocity of foam entering class C liquid shall not be greater than 6m / s. for water-soluble liquid storage tanks, foam buffer devices shall be provided.

3、每个泡沫产生器应用独立的混合液管道引致防火堤外。

3. Each foam generator shall be led out of the fire dike by an independent mixed liquid pipeline.

4、连接泡沫产生器的泡沫混合液立管应用关卡固定在管壁上，关卡间距不宜大于3m。

4. The foam mixed liquid riser connected to the foam generator shall be fixed on the pipe wall with gates, and the distance between gates shall not be greater than 3m.

5、防护堤外泡沫混合液或泡沫管道的设置要求：

5. Requirements for setting of foam mixed liquid or foam pipeline outside the protective Embankment:

①固定式液上喷射：每个泡沫产生器应在防护堤外独立设置控制阀。

① Fixed liquid jet: each foam generator shall be provided with an independent control valve outside the protective dike.

②半固定液上喷射：每个泡沫产生器应在防火堤距地0.7m设置带有门馆的管牙接口。

② Spray on semi fixed liquid: each foam generator shall be provided with a pipe thread interface with a door hall 0.7m above the ground.
