We use many fire smoke exhaust pipes in our daily life. The fire smoke exhaust system itself belongs to the important object of the public. However, the requirements for fire smoke exhaust and ventilation pipes are also very high. Generally speaking, strictly speaking, when selecting fire, smoke exhaust and ventilation ducts, the first consideration is flame retardancy. As we all know, fire fighting work is carried out in the environment of high temperature or even open fire, so the fire resistance and flame retardancy of ventilation pipes need to be considered. However, does the fire smoke exhaust pipe need fire prevention and insulation?

1、 排煙管可以保溫，因?yàn)楦鶕?jù)相關(guān)要求，特別是一些排煙管，周圍溫度可能比較高。如果不能滿足設(shè)置要求，應(yīng)結(jié)合管道間距采取保護(hù)措施。如果不能滿足20cm的要求，則需采取保溫保護(hù)。

1. The smoke exhaust pipe can be insulated, because according to relevant requirements, especially some smoke exhaust pipes, the surrounding temperature may be relatively high. If the setting requirements cannot be met, protective measures shall be taken in combination with the pipe spacing. If the requirement of 20cm cannot be met, thermal insulation protection shall be taken.

2、 有些排煙管不需要隔熱處理。如果其他條件滿足要求，也能在室外排放室內(nèi)煙氣，則無需再做保溫處理，也無需安裝普通排氣管。

2. Some smoke exhaust pipes do not need heat insulation. If other conditions meet the requirements and indoor flue gas can be discharged outdoors, there is no need to conduct thermal insulation treatment or install ordinary exhaust pipe.

事實(shí)上，消防排煙管道需要防火保溫處理，這對于在使用過程中有著重要的作用價值。

In fact, the fire exhaust pipe needs fire protection and thermal insulation treatment, which plays an important role in the use process.

如何控制地下室排風(fēng)排煙共用風(fēng)口？ 電氣上是否能控制不同防煙分區(qū)的風(fēng)口關(guān)閉？當(dāng)火災(zāi)唄確認(rèn)后，應(yīng)能開啟排煙區(qū)域的排煙口和排煙風(fēng)機(jī)，并自動關(guān)閉與排煙無關(guān)的通風(fēng)、空調(diào)系統(tǒng)。

How to control the common air outlet of basement exhaust and smoke exhaust? Can you electrically control the closing of air vents in different smoke prevention zones? When the fire is confirmed, it shall be able to turn on the smoke outlet and smoke exhaust fan in the smoke exhaust area, and automatically turn off the ventilation and air conditioning system irrelevant to smoke exhaust.

1、多個排煙分區(qū)合用排煙排風(fēng)系統(tǒng)，這種情況的話，電動閥+排煙風(fēng)口更好，平時常開排風(fēng)，著火關(guān)閉非著火點(diǎn)排煙分區(qū)的設(shè)置在支管上的電動閥，超過280度風(fēng)口熔斷關(guān)閉，煙氣如擴(kuò)散到其他防煙分區(qū)則開啟此防煙分區(qū)支管上的電動閥

1. Multiple smoke exhaust zones share the smoke exhaust system. In this case, the electric valve + smoke exhaust outlet is better. Usually, the exhaust is always open, and the electric valve set on the branch pipe of the smoke exhaust zone without ignition point is closed on fire. If the air outlet exceeds 280 degrees, it is fused and closed. If the smoke diffuses to other smoke prevention zones, open the electric valve on the branch pipe of this smoke prevention zone

2、一般住宅的地下室為儲藏功能，并劃分為小的儲藏間，排煙排風(fēng)系統(tǒng)合用，一套系統(tǒng)也就負(fù)責(zé)1個或者2個防煙分區(qū)，并且煙氣擴(kuò)散很快，閥門來回開啟與關(guān)閉，采用全部敞開的排煙風(fēng)口比較好，平時常開排風(fēng)，著火也全部開啟，超過280度關(guān)閉。

2. Generally, the basement of a residence is used for storage and is divided into small storage rooms. The smoke exhaust system is shared. A set of system is responsible for one or two smoke prevention zones, and the smoke diffuses quickly. The valves are opened and closed back and forth. It is better to use all open smoke exhaust outlets. It is usually open for exhaust, and all fire are opened, and closed at more than 280 degrees.
