As long as the ventilated environment can make the air refreshing, and this can not be separated from the ventilation project, the whole project will be based on the location of the affirmative plan, and ensure smooth ventilation, which central needs ventilation project?

　　一、建筑內(nèi)：應(yīng)設(shè)排煙設(shè)備，但不具備自然排煙條件的房間、走道及中庭等，均應(yīng)采用機(jī)械排煙方式。高層建筑主要受自然條件(如室外風(fēng)速、風(fēng)壓、風(fēng)向等)的影響會(huì)較大，普通采用機(jī)械排煙方式較多。

　　1. Inside buildings: smoke exhaust equipment should be installed, but mechanical smoke exhaust should be used in rooms, aisles and atriums that do not have natural smoke exhaust conditions. High-rise buildings are mainly affected by natural conditions (such as outdoor wind speed, wind pressure, wind direction, etc.). Mechanical smoke exhaust is commonly used.

　　二、人防工程下列部位：

　　2. The following parts of civil air defense works:

　　1、經(jīng)常有人停留的中央，或可燃物較多的房間、大廳；

　　1. The center where people often stay, or rooms or halls with more combustibles;

　　2、消費(fèi)車(chē)間需求通風(fēng)工程；

　　2. Demand ventilation engineering in consumer workshop;

　　3、長(zhǎng)度比擬長(zhǎng)的分散走道；

　　3. Distributed walkways with comparatively long lengths;

　　其實(shí)這些中央相對(duì)而言運(yùn)用通風(fēng)工程的中央比擬多，除此之外，凡是需求通風(fēng)的中央，也是需求它的，它的應(yīng)用范圍普遍。

　　In fact, these centers use ventilation engineering relatively more than the central, in addition, all the need for ventilation of the central, but also need it, its application is widespread.

　　通風(fēng)管道廠是工業(yè)與民用建筑的通風(fēng)與空調(diào)工程用金屬或復(fù)合管道，降落有害氣體濃度的一種市政根底設(shè)備。鄭州通風(fēng)管道制造時(shí)種類(lèi)比擬多，下面通風(fēng)管道的小編就為我們同享一下三通接通的優(yōu)勢(shì)，希冀對(duì)我們有所輔佐。

　　Ventilation Pipeline Plant is a kind of municipal basic equipment for ventilation and air conditioning engineering of industrial and civil buildings, which uses metal or composite pipes to reduce the concentration of harmful gases. There are many kinds of ventilation pipes in Zhengzhou when they are manufactured. The small edition of the ventilation pipes below will share the advantages of the three-way connection and hope to be helpful to us.

　　三通接口是一款三通管道接頭，適用于水、油品、蒸汽、酸性介質(zhì)等。三通接口，主要是用于三條管道的聯(lián)接，避免漏水、漏氣等。圓螺旋風(fēng)管及配件、扁圓螺旋風(fēng)管及配件是國(guó)外先進(jìn)螺旋風(fēng)管工藝制造技術(shù)，具有阻力小，強(qiáng)度高，耐腐蝕，內(nèi)壁外表光滑、平整、設(shè)備便當(dāng)，密封性好、圓螺旋風(fēng)管適用性強(qiáng)等特征，在大廈、超市、地道、工廠、酒店、陶瓷窯爐、吸塵等作業(yè)的通風(fēng)或冷暖氣的傳送普遍適用。螺旋風(fēng)管具有以下幾特征:強(qiáng)度好、阻力小、設(shè)備簡(jiǎn)單便當(dāng)、適用作業(yè)廣、螺旋風(fēng)管標(biāo)準(zhǔn)廣。

　　The three-way joint is a three-way pipe joint, which is suitable for water, oil, steam, acid medium, etc. The three-way interface is mainly used for the connection of three pipelines to avoid leakage of water and air. Circular spiral duct and fittings, flat spiral duct and fittings are the advanced manufacturing technology of spiral duct abroad. They have the characteristics of small resistance, high strength, corrosion resistance, smooth inner surface, flat surface, convenient equipment, good sealing and strong applicability of circular spiral duct. They are in buildings, supermarkets, tunnels, factories, hotels and ceramics. The ventilation or the transmission of cold and warm air in kiln, dust collection and other operations are generally applicable. The spiral duct has the following advantages: good strength, small resistance, simple and convenient equipment, wide application and wide standard of spiral duct.
