style="text-indent:25px">實驗室氣路系統(tǒng)主要由氣源切換系統(tǒng)、管道系統(tǒng)、壓力調(diào)節(jié)系統(tǒng)、氣點、監(jiān)控報警系統(tǒng)組成。對于一些易燃易爆氣體，如氫氣和乙炔，在設(shè)計和施工過程中可能會有細(xì)微差異，必須增加安全控制裝置，如氣體回火防止器。實驗室氣路系統(tǒng)選擇標(biāo)準(zhǔn)：供氣安全為主。根據(jù)國家相關(guān)法律法規(guī)，包括壓縮空氣在內(nèi)的所有壓縮氣體都是危險化學(xué)品，一旦發(fā)生了事故，就可能會造成嚴(yán)重的人身傷害。因此，只有供氣的基本功能遠(yuǎn)遠(yuǎn)不夠，還要保證足夠的安全性能。</p><p style="text-indent:25px">學(xué)校實驗室氣路安裝要求：1、所有氣體管道由好的、完全退火型、無縫連接的不銹鋼管道 (BA 級) 組成。銅管*在氣體管道末端使用，并且對氣體純度的要求也不是太嚴(yán)格的地方。2、氣路安裝管道不得與電纜、導(dǎo)線敷設(shè)在同一框架上。3、易燃?xì)怏w，如乙炔，需與其它氣體分開引入。如果氫氣管道與其他可燃?xì)怏w管道平行敷設(shè)，間距不應(yīng)小于 0.5 M; 交叉敷設(shè)時間距離不應(yīng)小于 0.25 M。分層鋪設(shè)時，氫管道應(yīng)位于上方。4、壓縮空氣在管道上的雜質(zhì)和濕氣有過濾凈化裝置。這種凈化裝置需要并聯(lián)一路，用單獨的閥門進行隔離，便于過濾裝置的維護。5 、高純度氣體管道的連接采用無縫焊接。只有在連接到閥門或調(diào)節(jié)裝置時，才能使用連接器配件。6 、各實驗室必須有單獨的控制閥、減壓閥、壓力表。7、通往工作臺的氣體管道應(yīng)配備單獨的控制閥。在工作臺上均勻排放各種氣體的控制閥。建議在 He氣管道前安裝氣體凈化裝置。8、氣體管道每 1.5 m左右需要一個支架。另外，根據(jù)氣體管道彎曲的半徑，設(shè)置合適的支架位置。必須所有彎曲點都要有支撐。氣路安裝的所有支架都應(yīng)進行鍍鋅和防腐處理。實驗室采用集中供氣的方式輸送高純氣體，可以保持氣體純度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
