通風管道是工業(yè)與民用建筑的通風與空調工程用金屬或非金屬管道,是為了使空氣流通,降低有害氣體濃度的一種市政基礎設備.今天我們就來了解一下通風管道安裝前的一些小學問:

Ventilation pipe is a kind of metal or nonmetal pipe used in ventilation and air conditioning engineering of industrial and civil buildings. It is a kind of municipal basic equipment to make the air circulate and reduce the concentration of harmful gases

1、應按某系統(tǒng)的某樓層通風管道中止繪制,并注明接口位置.

1. First of all, the drawing should be stopped according to the ventilation duct of a certain floor of a certain system, and the interface position should be indicated

2、通風管道設計應中止編號,從起點開端編號,起點普通為接口位置,相同斷面規(guī)格、相同長度節(jié)為同一號碼,除此應按次第編號.以便于組織制造施工.

2. In the design of ventilation duct, the numbering shall be stopped and the numbering shall start from the starting point. The starting point is the common interface position, and the same section specification and length section shall be the same number. In addition, the numbering shall be carried out according to the order, so as to organize the manufacturing construction

3、通風管道設計需標示支吊架位置,支吊架位置間距及一切材料規(guī)格需符后規(guī)范懇求及工藝規(guī)則.

3. The position of supports and hangers, the distance between supports and hangers, and all material specifications shall comply with the specifications and process rules

4、制造通風管道設應優(yōu)先思索彎頭與變徑滿足內外表面同心彎管懇求、變徑長度懇求.

4. In the design of ventilation duct, elbow and reducing should be considered to meet the requirements of concentric elbow and reducing length

5、通風管道設計應標示起端與彎頭位置、變徑位置、管線所處軸線位置、管底標高。

5. The position of starting end and elbow, the position of reducing diameter, the position of pipeline axis and the elevation of pipe bottom shall be marked in the design of ventilation pipe.
