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(fēng)管道加工的系統(tǒng)布局需遵循以下幾點(diǎn)：

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

一、系統(tǒng)網(wǎng)的布局形式

1、 Layout form of system network

為方便管網(wǎng)的管理和運(yùn)行調(diào)節(jié)，管網(wǎng)系統(tǒng)不宜過大，同一系統(tǒng)有多個(gè)分支管時(shí)，應(yīng)將這些分支管分級控制，且同一系統(tǒng)的吸氣點(diǎn)不宜過多，一定要注意各支管的壓力平衡。常用的管網(wǎng)布局方式有干管配管、個(gè)別配管、環(huán)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(fēng)管道安裝系統(tǒng)的鋪設(shè)原則

1. Laying principle of ventilation pipe installation system

管道鋪設(shè)分明裝、暗裝，一般采用明裝。因?yàn)槊餮b以便于檢修，在無法采用明裝時(shí)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(shè)，若管徑大或保溫應(yīng)布局在靠墻側(cè)。一般兩根管道平行布局時(shí)，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(fēng)管道加工系統(tǒng)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(yīng)設(shè)置足夠數(shù)量的法蘭連接，在以螺紋為主的連接管道中應(yīng)設(shè)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(fēng)管道加工系統(tǒng)的支撐原則管道不宜與閥件直接支撐在設(shè)備上，應(yīng)單獨(dú)設(shè)置支架或吊架，管道的焊縫位置應(yīng)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(zhì)不同，則凈化的分段處理應(yīng)不同。

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

當(dāng)污染源多時(shí)可以集中在一個(gè)凈化系統(tǒng)中，也可分為幾個(gè)系統(tǒng)，但出現(xiàn)污染物混合會引起燃燒、爆炸危險(xiǎn)、不同溫度和濕度的氣體，混合后出現(xiàn)管道內(nèi)結(jié)露、粉塵或氣體性質(zhì)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(fēng)管道加工系統(tǒng)布局中要保證整體系統(tǒng)的漏損小，確保吸塵口的有足夠的風(fēng)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(fēng)管道加工系統(tǒng)布局要減小阻力。

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