Dear friends, are you still worried about how to ensure the quality of air duct construction? I believe this is also the concern of consumers.

首先，為了使施工的效果更好，我們應制定一些嚴格的實行措施。一點，就是在施工前，根據施工的要求和施工的現場環境畫出施工圖和組織設計方案，并且在實施過程中嚴格按照施工圖和組織設計方案進行操作，不可隨意更改。

First of all, in order to make the construction effect better, we should formulate some strict implementation measures. One point is to draw the construction drawing and organization design scheme according to the construction requirements and the construction site environment before construction, and operate in strict accordance with the construction drawing and organization design scheme during implementation, which cannot be changed at will.

二點，對于施工中所要用到的材料質量應進行檢驗，如查看相關的合格證書，沒有問題后才可以用到施工中。

Second, the quality of materials to be used in construction shall be inspected. If there is no problem, they can be used in construction.

三點，施工中應嚴格按照國家出行的相關規定進行施工，從而保證施工的全性。

Third, the construction shall be carried out in strict accordance with the relevant national travel regulations, so as to ensure the integrity of the construction.

四點，對于施工中的人員的技術應進行指導，讓其掌握施工中的要領并進行實地的測量，記錄相關的測量數據，提高施工的質量。

Four points, technical guidance should be given to the personnel in construction, so that they can master the essentials in construction, carry out field measurement, record relevant measurement data and improve the quality of construction.

五點，依照合理的程序進行施工，檢查中發現問題要及時返修并予以相關的指導。

Five points: the construction shall be carried out according to reasonable procedures, and the problems found in the inspection shall be repaired in time and given relevant guidance.

六點，完善施工中的獎懲制度，在確保每個施工員的全的況下，對認真工作的施工員進行相應的獎勵，從而鼓勵大家重視施工的整體質量。

Six points, improve the reward and punishment system in construction, and reward the conscientious constructors under the condition of ensuring the integrity of each constructor, so as to encourage everyone to pay attention to the overall quality of construction.

后，在施工結束后相關的人員應仔細檢查施工記錄，對出現的問題及時提出并解決，確認沒有問題后，再進行交底工作。

After construction, relevant personnel shall carefully check the construction records, put forward and solve the problems in time, and conduct disclosure after confirming that there are no problems.

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 pipes in modern buildings is becoming more and more scientific. In the construction process, the general principle is that small pipes give way to large pipes: small pipes are easy to bend, and the cost is low. This principle is the avoidance principle.

小管讓大管：小管繞彎容易，且造價低。

Small tube makes big tube: small tube is easy to bend, and the cost is low.

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。

The branch pipe gives way to the main pipe: the diameter of the branch pipe is generally small. See 1 for the reasons for avoiding the ventilation pipe project. In addition, the influence scope and importance of the branch pipe are not as important as the main pipe.

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。

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 flow.

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。

The normal temperature pipe is replaced by the high (low) temperature pipe (the cold water pipe is replaced by the hot water pipe, and the non insulated pipe is replaced by the insulated pipe): the exhaust shall be considered when the ventilation pipeline project is higher than the normal temperature; If it is lower than normal temperature, anti condensation and thermal insulation shall be considered.

給水管讓排水管：除了上述3條原因外，通常排水管管徑大，且水中雜質多。

Water supply pipe and drainage pipe: in addition to the above three reasons, the diameter of the drainage pipe is usually large and there are many impurities in the water.

低壓管讓高壓管：高壓管造價高，且強度要求也高。

Low pressure pipe to high pressure pipe: high pressure pipe has high cost and high strength requirements.

氣體管讓水管：水流動的動力消耗大。

Gas pipe makes water pipe: the power consumption of water flow is large.

一般管道讓通風管：體積大，繞彎困難。

General ventilation pipe: large volume, difficult to bend.

金屬管讓非金屬管：金屬管易彎曲切割和連接。

Metal pipe allows non-metallic pipe: metal pipe is easy to bend, cut and connect.

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。

Small valves make more valves: installation, operation and maintenance of Shanxi oil fume purification system shall be considered.
