電氣上是否能控制不同防煙分區(qū)的風口關閉?當火災唄確認后，應能開啟排煙區(qū)域的排煙口和排煙風機，并自動關閉與排煙無關的通風、空調(diào)系統(tǒng)。

Whether can the electrical control different smoke preventing zoning tuyere close? When the fire Bai confirmation, should be able to open the exhaust area of the exhaust port and the exhaust fan, and automatically shut down ventilation, air conditioning system and smoke exhaust independent.

1、多個排煙分區(qū)合用排煙排風系統(tǒng)，排煙管道安裝的就是電動閥+排煙風口，平時常開排風，著火關閉非著火點排煙分區(qū)的設置在支管上的電動閥，超過280度風口熔斷關閉，煙氣如擴散到其他防煙分區(qū)則開啟此防煙分區(qū)支管上的電動閥。

1, a plurality of smoke control zones combined with smoke exhaust system, smoke exhaust pipe installation is electric valve + smoke outlet, usually open exhaust fan, fire electric valve non ignition smoke control zones set off on the branch pipe, more than 280 degrees air blown off, flue gas such as spread to other smoke preventing zoning is to open the anti electric smoke zoning branch pipe on the valve.

2、一般住宅的地下室為儲藏功能，并劃分為小的儲藏間，排煙排風系統(tǒng)合用，一套系統(tǒng)也就負責1個或者2個防煙分區(qū)，并且煙氣擴散很快。

2, the general residential basement for storage function, and is divided into small storeroom, smoke exhaust system combination, a set of system is also responsible for 1 or 2 smoke preventing zoning, and smoke spread quickly.

其實，閥門來回開啟與關閉，通風設備廠家認為這樣反而降低了系統(tǒng)的安全性，所以采用全部敞開的排煙風口比較好，平時常開排風，著火也全部開啟，超過280度關閉。

In fact, the valve to open and close the back and forth, ventilation equipment manufacturers think that it reduces the system security, so using the smoke exhaust all open the better, usually open ventilation, fire are all open, more than 280 degrees off.濟南油煙凈化器
