工厂、写字楼、酒店都会安装通风蜜桃成人在线精品视频，但是后期安装多少肯定和之前的建筑的管线等有不可避免的接触，那么通风蜜桃成人在线精品视频安装应该注意些什么呢？
The factory, the office building, the hotel will install the ventilation pipe, but the later installation is sure to have the inevitable contact with the pipeline of the building before, so what should the installation of the ventilation pipe be noticed?
1.施工前设备总管工程师应将各工种的管线、单线画在一张平面图上。每种蜜桃成人在线精品视频用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现问题，将问题解决在安装之前，以免影响后期工程进程。
Before construction, the chief engineer of the equipment shall draw the pipeline and single line of each type of work on a plan. Each type of pipe is used with a color pen. At all points of intersection, it should synthesize its elevation to see if there is any contradiction, find problems in time, and solve the problems before installation, so as not to affect the later engineering process.
2.解决各种通风蜜桃成人在线精品视频相碰及协调的原则，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。冷、热水管与下水管相碰，则应改变冷、热水的蜜桃成人在线精品视频。
The principles to solve the collision and coordination of various ventilation ducts are generally: "small pipes allow large pipes to be pressurized without pressure". For example, if the water pipe collides with the wind pipe, it should turn the water pipe. When cold and hot water pipes collide with the water pipes, the cold and hot water pipes should be changed.
3.为减少投资，节省空间，降低层高，有些敷设无坡度要求的蜜桃成人在线精品视频，可以穿梁敷设，比如自来水蜜桃成人在线精品视频，消防喷洒干管等，一切均合理规划。
In order to reduce investment, save space and reduce the height of layers, some pipes with no slope requirements can be laid with beams, such as water pipe, fire sprinkler, and so on. All of them are reasonably planned.
4.对于比较复杂的民用建筑，在设计阶段，暖通、水电、建筑等工种应协商好空间分隔，定出每种蜜桃成人在线精品视频的标高和可施工范围。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决定，以免出现不可预估的损失。
For more complex civil buildings, in the design stage, the HVAC, hydroelectric, building and other types of work should first negotiate a good space separation, set up the elevation and the scope of the construction of each kind of pipe. In general, we should not exceed the prescribed limits. In case of a separate section, it should be negotiated with other projects in order to avoid an unexpected loss.
