在市場高速發展的趨勢下，對通風管道的需求越來越高，在各個行業中，它已經成為人們生活中必不可少的一部份。通風管道系統加工的布局平整美觀、簡單緊湊、安裝、操作、檢修的方便等因素決定管道系統的合理性，應滿足平時排風與火災時排煙的要求。那么通風管道安裝的系統布局一般有哪些步驟？需要注意些什么？下面來聽聽通風管道加工的技術人員是怎么說的吧？

With the rapid development of the market, the demand for ventilation pipe is higher and higher. In various industries, it has become an essential part of people's life. The layout of the processing of the ventilation pipeline system is flat and beautiful, simple and compact, and the installation, operation, maintenance and other factors determine the rationality of the pipeline system, which should meet the requirements of ventilation and smoke exhaust in case of fire. So what are the general steps of the system layout for the installation of ventilation ducts? What should we pay attention to? Now let's listen to the technical personnel of ventilation pipe processing?

通風管道加工的系統布局需遵循以下幾點：

The following points shall be followed for the system layout of ventilation pipe processing:

一、系統網的布局形式

1、 Layout form of system network

為方便管網的管理和運行調節，管網系統不宜過大，同一系統有多個分支管時，應將這些分支管分級控制，且同一系統的吸氣點不宜過多，一定要注意各支管的壓力平衡。常用的管網布局方式有干管配管、個別配管、環狀配管3種。

In order to facilitate the management and operation regulation of the pipe network, the pipe network system should not be too large. When there are multiple branches in the same system, the branches should be controlled by levels, and the suction points of the same system should not be too many. It is necessary to pay attention to the pressure balance of each branch pipe. There are three types of pipe network layout: main pipe, individual pipe and ring pipe.

二、布局的原則

2、 Principles of layout

1、通風管道安裝系統的鋪設原則

1. Laying principle of ventilation pipe installation system

管道鋪設分明裝、暗裝，一般采用明裝。因為明裝以便于檢修，在無法采用明裝時考慮暗裝方式，管道盡可能的集中成列，盡量沿墻或柱子平行鋪設，若管徑大或保溫應布局在靠墻側。一般兩根管道平行布局時，間距不小于100～200mm。

The pipeline shall be installed in a clear and concealed manner, and generally installed in an open manner. Because the open installation is convenient for maintenance, the concealed installation method shall be considered when the open installation is not available. The pipes shall be arranged in rows as far as possible, and shall be laid parallel to the wall or column as far as possible. If the pipe diameter is large or the insulation shall be arranged on the wall side. Generally, when two pipelines are arranged in parallel, the spacing shall not be less than 100-200mm.

2、通風管道加工系統的連接原則

2. Connection principle of ventilation pipe processing system

在以焊接為主要連接方式方法的管道中，應設置足夠數量的法蘭連接，在以螺紋為主的連接管道中應設置足夠的活接頭，以便宜于安裝、拆卸、檢修。

In the pipeline with welding as the main connection method, a sufficient number of flange connections shall be set, and in the pipeline with thread as the main connection method, a sufficient number of movable joints shall be set, which is cheaper than installation, disassembly and maintenance.

3、通風管道加工系統的支撐原則管道不宜與閥件直接支撐在設備上，應單獨設置支架或吊架，管道的焊縫位置應在施工方便或受力較小的地方，焊縫不得位于支架處且距離不小于200mm。

3. The support principle of the processing system of the ventilation pipe is that the pipe should not be directly supported on the equipment with the valve, and the support or hanger should be set separately. The weld position of the pipe should be at the place where the construction is convenient or the stress is small, and the weld should not be at the support and the distance should not be less than 200 mm.

4、不同含塵氣體性質不同，則凈化的分段處理應不同。

4. If the properties of different dust containing gases are different, the subsection treatment of purification should be different.

當污染源多時可以集中在一個凈化系統中，也可分為幾個系統，但出現污染物混合會引起燃燒、爆炸危險、不同溫度和濕度的氣體，混合后出現管道內結露、粉塵或氣體性質不同，影響回收或凈化效率的。

When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, when pollutants are mixed, it will cause combustion, explosion hazard, gases with different temperature and humidity. After mixing, condensation, dust or gas properties in the pipeline will be different, which will affect the recovery or purification efficiency.

5、通風管道加工系統布局中要保證整體系統的漏損小，確保吸塵口的有足夠的風量。

5. In the layout of the ventilation pipe processing system, it is necessary to ensure that the leakage of the whole system is small and that the dust collector has sufficient air volume.

6、通風管道加工系統布局要減小阻力。

6. The layout of the ventilation pipe processing system should reduce the resistance.
