我们经常能够在通风管道施工现场有着密密麻麻的管道，不知道各个管道的使用用途，同时也不知道通风管道施工需要注意什么问题。今天就和排烟通风管道安装,跟小编一起来了解一下。
We often have dense pipes on the construction site of ventilation pipes. We don't know the purpose of each pipe and what problems need to be paid attention to in the construction of ventilation pipes. Today, I'm going to talk about the installation of smoke exhaust and ventilation pipes with Xiaobian.
常温管让高(低)温管(冷水管让热水管、非保温管让保温管)：通风管道工程高于常温要思考排气;低于常温要思考防结露保温。分支管让主干管：分支管通常管径较小，通风管道工程躲避，别的还有一点，分支管的影响规模和重要性不如主干管。
The normal temperature pipe allows the high (low) temperature pipe (the cold water pipe allows the hot water pipe, and the non insulated pipe allows the insulated pipe): when the ventilation pipeline engineering is higher than the normal temperature, the exhaust should be considered; Below normal temperature, anti condensation and thermal insulation shall be considered. The branch pipe gives way to the main pipe: the branch pipe usually has a small diameter, which is avoided by the ventilation pipe project. In addition, the influence scale and importance of the branch pipe are not as important as the main pipe.
有压管让无压管(压力流管让重力流管)：无压管(或重力流管)改动斜度和流向，对活动影响较大。小管让大管：小管绕弯简单，且造价低。给水管让排水管：除了上述第3条要素外，通常排水管管径大，且水中杂质多。
Pressure pipe to non pressure pipe (pressure flow pipe to gravity flow pipe): the non pressure pipe (or gravity flow pipe) changes the slope and flow direction, which has a great impact on the activity. Small tube to big tube: small tube bending is simple and low cost. Water supply pipe and drainage pipe: in addition to the above element 3, the diameter of the drainage pipe is usually large and there are many impurities in the water.
通常管道让通风管：体积大，绕弯困难。气体管让水管：水活动的动力耗费大。低压管让高压管：高压管造价高，且强度请求也高。给水管让排水管：除了上述第3条要素外，通常排水管管径大，且水中杂质多。金属管让非金属管：金属管易弯曲、切割和衔接。
Usually, the ventilation pipe is large and difficult to bend. Gas pipe makes water pipe: the power consumption of water activity is large. Low pressure pipe to high pressure pipe: high pressure pipe has high cost and high strength requirements. Water supply pipe and drainage pipe: in addition to the above element 3, the diameter of the drainage pipe is usually large and there are many impurities in the water. Metal pipe makes non-metallic pipe: metal pipe is easy to bend, cut and connect.
The above is a detailed introduction to the kitchen smoke hood of Jinan hotel. I hope it will be helpful to you If you have any questions, please contact us We will provide you with professional service http://www.jntfgd.com
