二、通風管道安裝技巧
Two, ventilation pipe installation skills
通風管道在現(xiàn)代修建上的運用越來越科學，在施工過程中整體準則是小管讓大管：小管繞彎容易，且造價低，這種準則便是躲避準則。信任很多人對通風管道工程中的躲避準則不清楚。
Ventilation pipes are used more and more scientifically in modern construction. In the construction process, the overall criterion is that small pipes make large pipes: small pipes bend easily, and the cost is low. This criterion is the evasion criterion. A lot of people believe that the avoidance criteria in ventilation piping engineering are not clear.
通風管道安裝注意事項
Matters needing attention in installation of ventilation pipes
1、小管讓大管：小管繞彎容易，且造價低。
1, the small tube allows the big pipe: the small pipe is easy to turn around, and the cost is low.
2、分支管讓主干管：分支管一般管徑較小，通風管道工程躲避理由見第1條，別的還有一點，分支管的影響范圍和重要性不如主干管。
2. Branch pipe to main pipe: Branch pipe generally smaller diameter, ventilation pipeline engineering evasion reasons see Article 1, there is another point, the influence of the scope and importance of branch pipe is not as important as the main pipe.
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)改動坡度和流向，對活動影響較大。
3. Pressure pipe to pressure pipe (pressure pipe to gravity pipe): Pressure pipe (or gravity pipe) to change the slope and direction of flow, the impact on the activity is greater.
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. Normal temperature pipe let high (low) temperature pipe (cold water pipe let hot water pipe, non-thermal insulation pipe let thermal insulation pipe): Ventilation pipeline project above normal temperature to consider exhaust; below normal temperature to consider anti-condensation insulation.
5、給水管讓排水管：除了上述第3條原因外，一般排水管管徑大，且水中雜質多。
5. Water supply pipe to let drainage pipe: In addition to the above reasons for the third article, the general drainage pipe diameter, and water impurities.
6、低壓管讓高壓管：高壓管造價高，且強度要求也高。
6. Low pressure tube allows high pressure pipe: high pressure pipe has high cost and high strength requirement.
7、氣體管讓水管：水活動的動力耗費大。
7, gas pipes make water pipes: the power of water activities is expensive.
8、一般管道讓通風管：體積大，繞彎困難。
8, the general duct allows ventilation pipe: large volume, difficult to turn around.
9、金屬管讓非金屬管：金屬管易彎曲、切開和銜接。
9, metal pipes allow non-metallic tubes: metal pipes are flexible, cut and connected.
10、閥件小的讓閥件多的：山西油煙凈化體系考慮設備、操作、維護等要素。
10. Small valve parts and more valve parts: Shanxi oil fume purification system considers equipment, operation, maintenance and other elements.
