鍍鋅板螺旋風(fēng)管制作加工工藝特點(diǎn)及優(yōu)勢(shì)

Characteristics and advantages of manufacturing and processing technology for galvanized sheet spiral air ducts

（1）外觀質(zhì)量高。成形后的風(fēng)管內(nèi)壁潤(rùn)滑，外壁流利；

(1) High appearance quality. The inner wall of the formed air duct is lubricated, and the outer wall is smooth;

（2）風(fēng)管強(qiáng)度大。由于外壁咬口構(gòu)成的螺旋線棱筋平均散布，起到一個(gè)平均增強(qiáng)筋的效果，其單元強(qiáng)度大于通俗咬口式風(fēng)管；

(2) The strength of the air duct is high. Due to the evenly distributed spiral ribs formed by the bite on the outer wall, they have an average reinforcing effect, and their unit strength is greater than that of the common bite style air duct;

（3）風(fēng)管密封功能優(yōu)越。由于是機(jī)械加工，能削減報(bào)酬操作掉誤，確保風(fēng)管緊密，漏風(fēng)量遠(yuǎn)小于現(xiàn)行標(biāo)準(zhǔn)規(guī)則值；

(3) The sealing function of the air duct is superior. Due to its mechanical processing, it can reduce the cost of compensation and ensure that the air ducts are tight, and the air leakage rate is much lower than the current standard rules;

（4）資料用量削減。因?yàn)槁菪斤L(fēng)管單元強(qiáng)度大于通俗風(fēng)管，故同類規(guī)格風(fēng)管所用的卷材厚度可以減小一個(gè)型號(hào)，且風(fēng)管節(jié)長(zhǎng)比通俗咬口式風(fēng)管大，相同長(zhǎng)度的風(fēng)管節(jié)口數(shù)目分明削減，加之采用無(wú)法蘭銜接，可節(jié)流很多原資料；

(4) Reduce data usage. Because the strength of the spiral type air duct unit is greater than that of the ordinary air duct, the thickness of the coil used for similar specifications of air ducts can be reduced by one model, and the length of the air duct section is larger than that of the ordinary bite type air duct. The number of air duct sections of the same length is significantly reduced, and the use of flange free connections can save a lot of raw materials;

（5）加工速度快、精度高。由于是機(jī)械流水線加工，可不受功課手技能程度制約，對(duì)進(jìn)步風(fēng)管加工質(zhì)量非常有益。

(5) Fast processing speed and high precision. As it is a mechanical assembly line processing, it is not limited by the skill level of the workers, which is very beneficial for improving the quality of air duct processing.

什么是通風(fēng)管道及其產(chǎn)品特點(diǎn)淺析？

What is ventilation duct and its product characteristics?

1、通風(fēng)管道防火性能好：當(dāng)前普遍存在的問(wèn)題是成品通風(fēng)道燃燒性能和耐火限未經(jīng)家有關(guān)部門檢測(cè)，且部分通風(fēng)道材料的燃燒性能、管壁厚度不符合要求。

1. Good fire resistance performance of ventilation ducts: The current common problem is that the combustion performance and fire resistance limit of finished ventilation ducts have not been tested by relevant departments at home, and the combustion performance and wall thickness of some ventilation duct materials do not meet the requirements.

2、造價(jià)低：通風(fēng)管道與傳統(tǒng)磚砌通風(fēng)道比，能節(jié)約工程造價(jià)40%左右；

2. Low cost: Compared to traditional brick ventilation ducts, ventilation ducts can save about 40% of project cost;

3、輕質(zhì)高強(qiáng)：與傳統(tǒng)磚砌通風(fēng)道比，菱鎂通風(fēng)道自重輕、強(qiáng)度高，能大幅度降低建筑物的承受荷載；

3. Lightweight and High Strength: Compared with traditional brick ventilation ducts, magnesite ventilation ducts have a lighter weight and higher strength, which can significantly reduce the load-bearing capacity of buildings;

4、設(shè)計(jì)靈活：通風(fēng)管道可根據(jù)預(yù)留洞的大小，隨時(shí)調(diào)整管道的規(guī)格尺寸；

4. Flexible design: The ventilation duct can be adjusted in size according to the reserved hole size at any time;

5、設(shè)計(jì)獨(dú)特：通風(fēng)管道的開(kāi)口上安裝了煙氣止回閥和防火隔離門，可以有效防止串味和串火；

5. Unique design: The opening of the ventilation duct is equipped with a smoke check valve and a fire isolation door, which can effectively prevent odor and fire;

6、通風(fēng)管道施工簡(jiǎn)單，增加了室內(nèi)空間，密閉性好、不返煙、不返臭，能大幅度改善室內(nèi)環(huán)境。

6. The construction of ventilation ducts is simple, increasing indoor space, with good sealing, no smoke or odor return, and can greatly improve the indoor environment.
