专注通风管道加工·排烟罩

First of all, the ventilation duct has good fire resistance: the current common problem is that the combustion performance of the finished ventilation duct has not been tested by the relevant department, and the combustion performance and pipe wall thickness of some ventilation duct materials do not meet the requirements. Secondly, the cost is low: compared with the traditional brick ventilation duct, the ventilation duct can save the project cost; compared with the traditional brick ventilation duct, the magnesite ventilation duct has light weight and high strength, which can greatly reduce the bearing load of the building; Flexible design: the size of the ventilation pipe can be adjusted at any time according to the size of the reserved hole; Fifth, the design is unique: flue gas check valve and fire isolation door are installed on the opening of the ventilation pipe, which can prevent cross smell and cross fire; Simple construction: increased indoor space, good airtightness, no smoke, no odor, can greatly change the indoor environment.

对于比较复杂的民用建筑，在设计阶段，各工种应该协商好空间分隔，定出每种管道的标高范围。

For more complex civil buildings, in the design phase, each type of work should negotiate space separation and determine the elevation range of each type of pipe.

一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。其次解决各种通风管道相碰及协调的原则，一般为：“小管让大管，有压让无压”。例如，自来水管与风管相撞，则应当自来水管拐弯。

In general, you should not exceed the limits set for yourself. In case of pipeline section crossing the boundary, it shall negotiate with other projects. Secondly, the principle to solve the collision and coordination of various ventilation pipes is generally: "small pipes give way to large ones, and pressure gives way to non pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn.

冷、热水管与下水管相碰，则应改变冷、热水管道。再有施工前应设备总管的工程师，将各工种的管线，单线画在一张的平面图上。

If the cold and hot water pipes collide with the sewer pipe, the cold and hot water pipes shall be changed. Before construction, the engineer in charge of equipment shall draw the pipelines and single lines of various types of work on a plan.

每种管道用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题解决在安装之前。为了减少投资，节省空间，降低层高，有些敷设无坡度要求的管道，可以穿梁敷设(如自来水管道，消防喷洒干管等)。

One color pen for each type of pipe. The elevation of each intersection shall be integrated to see if there is any contradiction, and the problem shall be solved before installation. In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as water supply pipes, fire sprinkler main pipes, etc.).

山东厨房排烟设备通风管道从建筑结构设计来看由于有主、副烟道之分是不能随意横向改动的，否则会影响排烟并有倒灌的可能，将烟道口上下移动则不会有影响。再有就是特别是饭店的通风管道安装，在通风管道的选择上更要注意，好的通风管道具有非常多的优势，使用的全部都是不锈钢材质的通风管道一点是看烟机的形式，如果是西式烟机一般烟道的走向为垂直向上，外加不锈钢烟道装饰板，烟道口可改入吊顶内，如果是中式烟机由于烟道导管外一般无装饰板，则烟道口需改在吊顶下适当位置，以便烟道导管经装饰板或从烟机吊柜内同烟机连接。

From the perspective of architectural structure design, the ventilation duct of smoke exhaust equipment in Shandong kitchen can not be changed horizontally at will due to the difference between main flue and auxiliary flue, otherwise it will affect the smoke exhaust and have the possibility of back pouring. Moving the flue mouth up and down will not have an impact. In addition, especially for the installation of ventilation ducts in hotels, we should pay more attention to the selection of ventilation ducts. Good ventilation ducts have many advantages. All the ventilation ducts made of stainless steel are in the form of flue gas fans. For western style flue gas fans, the general flue direction is vertical upward, and stainless steel flue decorative plates are added. The flue opening can be changed into the ceiling, If there is generally no decorative plate outside the flue duct of the Chinese type flue gas turbine, the flue opening shall be changed to an appropriate position under the ceiling so that the flue duct can be connected to the flue gas turbine through the decorative plate or from the flue gas turbine cabinet.
