通風(fēng)管道是用于自然通風(fēng)以及工業(yè)生產(chǎn)和工業(yè)建筑物中通風(fēng)項(xiàng)目的金屬或復(fù)合管道，這是一種室內(nèi)通風(fēng)，可減少城市基礎(chǔ)設(shè)施中有害物質(zhì)的濃度。關(guān)于通風(fēng)管道工程項(xiàng)目安裝的關(guān)鍵點(diǎn)，下面就為大家簡單介紹。
Ventilation duct is a kind of metal or composite pipe used for natural ventilation and ventilation projects in industrial production and industrial buildings. It is a kind of indoor ventilation, which can reduce the concentration of harmful substances in urban infrastructure. On the key points of ventilation pipeline project installation, the following is a brief introduction.
在安裝通風(fēng)管道之前，需要仔細(xì)檢查貨物，驗(yàn)證是否有證明書和產(chǎn)品規(guī)格來建立原始的恒壓條件，產(chǎn)品密封是否完好以及外觀是否無效。當(dāng)鉛封損壞且原始固定壓力不符合工程設(shè)計(jì)壓力時(shí)，應(yīng)重復(fù)抗壓強(qiáng)度和氣密性測試。在整個(gè)安裝過程中應(yīng)用安全系數(shù)很方便，避免了安裝后無法使用它的情況。
Before installing the ventilation duct, it is necessary to carefully inspect the goods to verify whether there are certificates and product specifications to establish the original constant pressure conditions, whether the product seal is intact and whether the appearance is invalid. When the lead seal is damaged and the original fixed pressure does not meet the engineering design pressure, the compressive strength and air tightness test shall be repeated. It is very convenient to apply the safety factor in the whole installation process to avoid the situation that it cannot be used after installation.

安裝安全閥并通過鉆孔和焊接將其連接到機(jī)械設(shè)備和管道時(shí)，通風(fēng)管道工程圖的孔徑應(yīng)與安全閥的外徑相同。帶環(huán)法蘭的安全閥用于焊接短法蘭管，鉆孔后長度不超過120mm。安全閥應(yīng)以環(huán)形法蘭的形式安裝，安全閥用螺栓固定到位。鉆孔后，焊接一段不大于100mm的英制螺紋管，并安裝安全閥螺栓。嚴(yán)格管理中間標(biāo)準(zhǔn)，而不是輕載，這會(huì)縮短管道的使用壽命。
When installing a safety valve and connecting it to mechanical equipment and piping by drilling and welding, the hole diameter of the ventilation pipe engineering drawing shall be the same as the outer diameter of the safety valve. The safety valve with ring flange is used for welding short flange pipe, and the length after drilling shall not exceed 120mm. The safety valve shall be installed in the form of ring flange, and the safety valve shall be bolted in place. After drilling, weld a section of inch thread pipe no more than 100 mm, and install the safety valve bolt. Strict management of intermediate standards, rather than light loads, will shorten the service life of the pipeline.
通過上述的介紹，相信大家對通風(fēng)管道工程項(xiàng)目安裝的關(guān)鍵點(diǎn)有更深入的認(rèn)識(shí)和了解，感謝大家的觀看，如有需要，可以直接電話聯(lián)系我司。
