多叶排烟口和多叶送风口只要一字之差,看起来像是一种东西,其实不然,多叶排烟口与多叶送风口的制造工艺尽管相同,结构也没有差异,可是它们在应用上仍是存有很大的

差异的,今日小编就给我们介绍一下多叶排烟口和多叶送风口的差异吧。正压送风机向逃生楼道里送风的风机。它将室外风压送入室内。当建筑物发生火灾时,会产生大量烟雾

、一氧化碳等有毒气体并遮挡视线,通过正压送风机给逃生的消防楼梯送风,使室内的烟雾不能抵达楼梯,给人们逃生创造条件。

多叶送风口大多数都装置在建筑物(building)的楼梯间或走廊上,平常是呈封闭的状况的,一旦发作火灾DC24V直流电信号长途翻开风口,体系内相应的风机(Draught Fan)就会协

同作业将烟道内的烟气及时的运送出去。

多叶排烟口一般装置在过道、电梯口、管道或许排烟室前或许无窗户的房间里,不同之处就不同在它会将楼梯间或许走廊里的烟气排向外部,送风与排烟的作业由体系内的风

机(Draught Fan)来完结,它只需要收到信号时将风口翻开就完结它的使命了。混流风机风压系数比轴流风机高,流量系数比离心风机大,用在风压和流量都“不大不小”的场合。

它填补了轴流风机和离心风机之间的空白。同时具备安装简单方便的特点。

多叶排烟口和多叶送风口的意图就是为了当发作火灾时,及时的经过风管将烟气排出,运送进新鲜的空气来,保证人员和抢险人员在进行救活抢险救援时吸入对人体有害毒气、

烟雾、悬浮于空气中的有害污染物,保证有连绵不断的新鲜的空气进入保证被困的人们正常的呼吸。正压送风机一般装于建筑物顶,与各层的正压风阀联动。火灾初期时打开风阀,

启动正压送风机,使楼梯间、电梯厅处于正压状态(送风状态)。一般在楼内各层风井设置百叶,做送风窗口用,各层开口风井不同,设置单双层,保证风压;或设加压送风口,

有时会带手动及遥控装置,可控制送风量。

As long as there is a word difference between the multi leaf smoke outlet and the multi leaf air supply outlet, it looks like a kind of thing. In fact, although the manufacturing

 process of the multi leaf smoke outlet and the multi leaf air supply outlet is the same and there is no difference in structure, they are still quite different in application. Today's

 editor will introduce the difference between the multi leaf smoke outlet and the multi leaf air supply outlet. Positive pressure supply fan is the fan that supplies air to the escape

 corridor. It sends the outdoor wind pressure into the room. When a building fires, a large number of toxic gases such as smoke and carbon monoxide will be produced and the

 sight will be blocked. The positive pressure air blower will supply air to the escape fire stairs, so that the indoor smoke can not reach the stairs, creating conditions for people to

escape.


Most of the multi leaf air supply outlets are installed in the staircases or corridors of buildings, usually in a closed condition. Once the DC24V DC electrical signal of a fire breaks

 out, the corresponding draught fan in the system will work together to transport the flue gas in time.


Multi leaf smoke vent is generally installed in the corridor, elevator entrance, pipeline or room without windows. The difference is that it will exhaust the smoke in the stairwell or 

corridor to the outside. The operation of air supply and smoke exhaust is completed by the draught fan in the system. It only needs to open the air vent when receiving the signal

 to finish its mission. The air pressure coefficient of the mixed flow fan is higher than that of the axial flow fan, and the flow coefficient is larger than that of the centrifugal fan. It fills 

the gap between axial flow fan and centrifugal fan. At the same time, it has the characteristics of simple and convenient installation.
