低倍數泡沫滅火系統的內外浮頂指代什么？實際上這個操作在使用中還是很重要的，下面
川消小編就來為您講講吧。
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.
低倍數泡沫滅火系統--外浮頂
Low expansion foam fire extinguishing system -- external floating roof
1、飛水溶性液體的泡沫混合液提供強度不應小于12.5L/(min.m)，連續供給不應小于30min2、外浮頂檐口設計①泡沫堰板高出密封0.2m。設在擋雨板下泡沫堰板不應小于0.3m。
1. The supply strength of foam mixed liquid of water-soluble liquid shall not be less than 12.5l / (min.m), and the continuous supply shall not be less than 30min2. External floating roof cornice design: ① the foam weir plate shall be 0.2m higher than the seal. The foam weir plate set under the rain shield shall not be less than 0.3m.
②泡沫噴射口泡沫堰板與管壁有不應小于0.6m間距。噴射口在浮頂上時，泡沫堰板與管壁不宜小于0.6間距。
② The spacing between the foam weir plate at the foam injection port and the pipe wall shall not be less than 0.6m. When the injection port is on the floating roof, the spacing between the foam weir plate and the pipe wall should not be less than 0.6.
低倍數泡沫滅火系統--內浮頂
Low expansion foam fire extinguishing system -- inner floating roof
1、泡沫堰板與管壁間距不應小于0.55m，高度不應小于0.5m2、單個泡沫產生器保護周長不應大于24m3、非水溶液體的泡沫混合液供給強度不應小于12.5L(min.m)，連續供給不應小于30min。
1. The distance between the foam weir plate and the pipe wall shall not be less than 0.55M, the height shall not be less than 0.5m2, the protection perimeter of a single foam generator shall not be greater than 24m3, the supply intensity of the foam mixed liquid of non water soluble liquid shall not be less than 12.5l (min.m), and the continuous supply shall not be less than 30min.
低倍數泡沫滅火系統--固定頂設施要求
Low expansion foam fire extinguishing system -- Requirements for fixed roof facilities
1、非水溶性泡沫液儲罐液下半液下噴射，起泡沫混合液供給強度不應小于5L/(min.m)，連續供給不應小于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、泡沫進入甲乙液體的速度不應大于3m/s；泡沫進入丙類液體速度不應大于6m/s，對于水溶性液體儲罐來說，應設置泡沫緩沖裝置。
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、每個泡沫產生器應用獨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、連接泡沫產生器的泡沫混合液立管應用關卡固定在管壁上，關卡間距不宜大于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、防護堤外泡沫混合液或泡沫管道的設置要求：
5. Requirements for setting of foam mixed liquid or foam pipeline outside the protective Embankment:
①固定式液上噴射：每個泡沫產生器應在防護堤外獨立設置控制閥。
① Fixed liquid jet: each foam generator shall be provided with an independent control valve outside the protective dike.
②半固定液上噴射：每個泡沫產生器應在防火堤距地0.7m設置帶有門館的管牙接口。
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.
③泡沫混合液管道或泡沫管道上應設置放空閥且其管道應有2%的坡度破相放空閥。
③ Vent valve shall be set on foam mixed liquid pipeline or foam pipeline, and the pipeline shall be provided with 2% gradient phase break vent valve.
