Nowadays, Jinan ventilation pipe processing is very common in our daily life. With the continuous development of economy, more and more people choose this kind of pipeline. But how much do you know about it? Do you know which layout points should be followed when dealing with this pipeline? If you don't know, follow up and learn!

1、支撐原則

1. Supporting principle

管道不應(yīng)直接支撐在有閥門(mén)部件的設(shè)備上，應(yīng)單獨(dú)設(shè)置支架或吊架。管道的焊接位置應(yīng)在施工方便或應(yīng)力小的地方。焊縫不應(yīng)位于支架上，距離不應(yīng)小于200毫米

The pipeline shall not be directly supported on the equipment with valve components, and the support or hanger shall be set separately. The welding position of the pipeline should be in the place where the construction is convenient or the stress is small. The weld shall not be located on the support and the distance shall not be less than 200 mm

2、管道加工系統(tǒng)網(wǎng)的布局形式

2. Layout form of pipeline processing system network

為了便于管網(wǎng)的管理和運(yùn)行調(diào)整，管網(wǎng)系統(tǒng)不宜過(guò)大。當(dāng)同一系統(tǒng)有多個(gè)支管時(shí)，這些支管應(yīng)分級(jí)控制，同一系統(tǒng)的吸入點(diǎn)不應(yīng)過(guò)多。需要注意每個(gè)支管的壓力平衡。有三種常見(jiàn)的管網(wǎng)布局模式：主管、單管和環(huán)管。

In order to facilitate the management and operation adjustment of the pipe network, the pipe network system should not be too large. When there are more than one branch pipe in the same system, these branch pipes should be controlled by stages, and the suction points of the same system should not be too many. Attention should be paid to the pressure balance of each branch pipe. There are three common pipe network layout modes: main pipe, single pipe and loop pipe.

3、鋪設(shè)原則

3. Laying principle

管道敷設(shè)應(yīng)采用明裝暗裝，一般采用明裝。因?yàn)槊餮b便于維護(hù)，當(dāng)無(wú)法使用外露安裝時(shí)，考慮采用隱蔽安裝方式。

The pipeline shall be installed in an open and concealed manner, generally in an open manner. Because the surface installation is easy to maintain, when the exposed installation cannot be used, the concealed installation method should be considered.

管道應(yīng)盡可能成列布置，并盡可能沿墻或柱平行敷設(shè)。如果管徑較大或保溫應(yīng)設(shè)在墻側(cè);一般情況下，兩條管道平行敷設(shè)時(shí)，間距不應(yīng)小于100 ~ 200毫米

Pipes shall be arranged in rows as far as possible and parallel to walls or columns as far as possible. If the pipe diameter is large or the insulation should be set at the wall side; in general, when two pipes are laid in parallel, the spacing should not be less than 100 ~ 200 mm

4、不同的含塵氣體性質(zhì)不同，分段處理的凈化應(yīng)不同。

4. Different dust containing gases have different properties, so the purification of segmented treatment should be different.

當(dāng)污染源長(zhǎng)時(shí)間集中在一個(gè)凈化系統(tǒng)中時(shí)，它們可以分為幾個(gè)系統(tǒng)。然而，污染物的混合會(huì)導(dǎo)致燃燒、爆炸危險(xiǎn)以及不同溫度和濕度的氣體。混合后，管道中會(huì)出現(xiàn)冷凝、灰塵或不同性質(zhì)的氣體，影響回收或凈化效率。

When pollution sources are concentrated in one purification system for a long time, they can be divided into several systems. However, the mixing of pollutants can lead to combustion, explosion hazard and gases with different temperature and humidity. After mixing, condensation, dust or gases with different properties will appear in the pipeline, which will affect the recovery or purification efficiency.

5、通風(fēng)管道處理系統(tǒng)連接原則

5. Connection principle of ventilation duct treatment system

以焊接為主要連接方式的管道，應(yīng)設(shè)置足夠數(shù)量的法蘭連接，以螺紋為主要連接方式的管道，應(yīng)設(shè)置足夠數(shù)量的柔性接頭，以適合安裝、拆卸和檢修。

For pipelines with welding as the main connection mode, sufficient flange connections shall be set; for pipelines with thread as the main connection mode, enough flexible joints shall be set to suit for installation, disassembly and maintenance.

6、布局要保證整個(gè)系統(tǒng)的泄漏量小，要保證吸塵口有足夠的風(fēng)量;減少阻力。

6. The layout should ensure that the leakage of the whole system is small, there should be enough air flow at the dust suction port, and the resistance should be reduced.

7、風(fēng)管的布置應(yīng)盡量減少其長(zhǎng)度和不必要的轉(zhuǎn)彎。空調(diào)箱應(yīng)位于地下室內(nèi)。

7. The layout of air duct should minimize its length and unnecessary turning. The air conditioning box shall be located in the basement.

濟(jì)南通風(fēng)管道廣泛應(yīng)用于公共設(shè)施領(lǐng)域，是酒店的排煙設(shè)備，空調(diào)通風(fēng)設(shè)備是典型的通風(fēng)管道。通風(fēng)設(shè)備和管道設(shè)備制造商有自己的進(jìn)料方法和特殊的原料進(jìn)料通道。每種材料都有質(zhì)量檢驗(yàn)證書(shū)，以確保其性能。

Jinan ventilation pipe is widely used in the field of public facilities. It is the smoke exhaust equipment of hotel, and the air conditioning ventilation equipment is a typical ventilation pipe. Manufacturers of ventilation and plumbing equipment have their own feeding methods and special raw material feeding channels. Each material has a quality inspection certificate to ensure its performance and safety.
