快盈11v通风管道施工如何进行避让?

通风管道在现代建筑上的使用越来越科学,在施工过程中总体原则是小管让大管:小管绕弯容易,且造价低,这种原则即是避让原则:

The use of ventilation ducts in modern buildings is becoming increasingly scientific. The overall principle during construction is that small pipes give way to large pipes: small pipes are easy to bend and have low cost. This principle is known as the avoidance principle:

快盈11v1、小管让大管:小管绕弯容易,且造价低。

快盈11v1. Small pipes make big pipes: Small pipes are easy to bend and have a low cost.

2、分支管让主干管:分支管一般管径较小,通风管道工程避让理由见第1条,另外还有一点,分支管的影响范围和重要性不如主干管。

2. Branch pipes give way to main pipes: Branch pipes are generally smaller in diameter, and the reasons for avoiding ventilation pipeline engineering are shown in the first point. In addition, the influence and importance of branch pipes are not as great as that of main pipes.

3、有压管让无压管(压力流管让重力流管):无压管(或重力流管)改变坡度和流向,对流动影响较大。

快盈11v3. Pressure pipes replace non pressure pipes (pressure flow pipes replace gravity flow pipes): Non pressure pipes (or gravity flow pipes) change slope and flow direction, which has a significant impact on flow.

快盈11v4、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考虑排气;低于常温要考虑防结露保温。

快盈11v4. Room temperature pipes give way to high (low) temperature pipes (cold water pipes give way to hot water pipes, non insulated pipes give way to insulated pipes): For ventilation pipeline projects above room temperature, exhaust should be considered; When it is below room temperature, anti condensation and insulation should be considered.

5、给水管让排水管:除了上述第3条原因外,通常排水管管径大,且水中杂质多。

快盈11v5. Water supply pipes give way to drainage pipes: In addition to the third reason mentioned above, drainage pipes usually have a larger diameter and more impurities in the water.

6、低压管让高压管:高压管造价高,且强度要求也高。

6. Low pressure pipes give way to high pressure pipes: High pressure pipes are expensive and require high strength.

7、气体管让水管:水流动的动力消耗大。

7. Gas pipes make water pipes: the power consumption of water flow is high.

8、一般管道让通风管:体积大,绕弯困难。

8. Generally, ventilation pipes are bulky and difficult to bend.

快盈11v9、金属管让非金属管:金属管易弯曲、切割和连接。

快盈11v9. Metal pipes make non-metallic pipes easier to bend, cut, and connect.

10、阀件小的让阀件多的:山西油烟净化系统考虑安装、操作、维护等因素。

10. Small valves make more valves: Shanxi oil fume purification system considers factors such as installation, operation, and maintenance.
