    通風管道施工如何進行避讓?

    通風管道在現代建筑上的使用越來越科學,在施工過程中總體原則是小管讓大管:小管繞彎容易,且造價低,這種原則即是避讓原則:

    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:

    1、小管讓大管:小管繞彎容易,且造價低。

    1. Small pipes make big pipes: Small pipes are easy to bend and have a low cost.

    2、分支管讓主干管:分支管一般管徑較小,通風管道工程避讓理由見第1條,另外還有一點,分支管的影響范圍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、有壓管讓無壓管(壓力流管讓重力流管):無壓管(或重力流管)改變坡度和流向,對流動影響較大。

    3. 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.

    4、常溫管讓高(低)溫管(冷水管讓熱水管、非保溫管讓保溫管):通風管道工程高于常溫要考慮排氣;低于常溫要考慮防結露保溫。

    4. 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、給水管讓排水管:除了上述第3條原因外,通常排水管管徑大,且水中雜質多。

    5. 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、低壓管讓高壓管:高壓管造價高,且強度要求也高。

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

    7、氣體管讓水管:水流動的動力消耗大。

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

    8、一般管道讓通風管:體積大,繞彎困難。

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

    9、金屬管讓非金屬管:金屬管易彎曲、切割和連接。

    9. Metal pipes make non-metallic pipes easier to bend, cut, and connect.

    10、閥件小的讓閥件多的:山西油煙凈化系統考慮安裝、操作、維護等因素。

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