通風(fēng)管道常見(jiàn)的特色有哪些?
1、防火功用好：其時(shí)普遍存在的問(wèn)題是制品通風(fēng)道燃燒功用和耐火極限未經(jīng)有關(guān)部門(mén)檢測(cè)，且部分通風(fēng)道材料的燃燒功用、管壁厚度不符合要求。
1. Good fireproof function: At that time, the common problem was that the burning function and fireproof limit of product ventilation duct had not been inspected by relevant state departments, and the burning function and wall thickness of some ventilation duct materials did not meet the requirements.
2、造價(jià)低：濟(jì)南通風(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: Jinan ventilation duct can save about 40% of the project cost compared with the traditional brick ventilation duct.
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，能大幅度下降建筑物的承受荷載;
3. Light weight and high strength: Compared with traditional brick ventilation duct, magnesite ventilation duct has light weight and high strength, which can greatly reduce the bearing load of buildings.
4、規(guī)劃活絡(luò)：通風(fēng)管道可根據(jù)預(yù)留洞的巨細(xì)，隨時(shí)調(diào)整管道的標(biāo)準(zhǔn)標(biāo)準(zhǔn);
4. Planning flexible network: ventilation pipeline can adjust the standard standard of pipeline at any time according to the size of reserved holes;
5、規(guī)劃一起：通風(fēng)管道的開(kāi)口上裝置了煙氣止回閥和防火阻隔門(mén)，可以有用防止串味和串火;

5. Planning together: flue gas check valves and fire barrier doors are installed at the opening of the ventilation pipeline, which can be used to prevent cross-smelling and crossfire.
6、施工簡(jiǎn)略：增加了室內(nèi)空間，密閉性好、不返煙、不返臭，能大幅度改進(jìn)室內(nèi)環(huán)境。
6. Brief construction: Increased indoor space, good airtightness, no smoke return, no odor return, can greatly improve the indoor environment.
螺旋風(fēng)管在作業(yè)進(jìn)程會(huì)發(fā)生必定的噪音，假定在住宅區(qū)和商業(yè)區(qū)會(huì)對(duì)人們的日子發(fā)生很大的影響。那么我們?cè)谑┕みM(jìn)程中怎么削減噪音呢？
The helical duct will produce certain noise in the process of operation, assuming that in residential and commercial areas will have a great impact on people's lives. So how do we reduce noise in the construction process?
通風(fēng)管道體系作業(yè)噪音一般來(lái)源于以下幾個(gè)方面:
The working noise of ventilation duct system generally comes from the following aspects:
風(fēng)管的顫動(dòng)。因?yàn)轱L(fēng)管材料是鍍鋅板或者是金屬材料，在施工時(shí)要嚴(yán)峻按照施工檢驗(yàn)標(biāo)準(zhǔn)選擇鋼板厚度和施工工藝，比如風(fēng)管制作差錯(cuò)、平直度、風(fēng)管加固、支吊架選擇及制作設(shè)備等等。到了施工階段，出風(fēng)口盡量不要挨近設(shè)備。電扇前后盡量都有5米以上的長(zhǎng)度。假定可以增加彎頭數(shù)目也可以下降噪音，風(fēng)口加裝過(guò)濾網(wǎng)，噪音操控作用也很好。
Flutter of air duct. Because the material of air duct is galvanized sheet or metal material, the thickness of steel plate and construction technology should be strictly selected according to construction inspection standards, such as air duct errors, flatness, air duct reinforcement, support and hanger selection and production equipment, etc. At the construction stage, the outlet should not be close to the equipment as far as possible. The length of the electric fan should be more than 5 meters before and after it. It is assumed that the number of elbows can be increased and the noise can be reduced. A filter is installed in the tuyere, and the noise control function is also very good.
