10.0mm。同時玻璃透明件一般應(yīng)以內(nèi)腔安裝，因為當(dāng)內(nèi)部有壓力時，彈性密封墊趨于壓縮狀態(tài)，會加強密封性能。彈性密封墊的材質(zhì)，一般采用丁腈橡膠；當(dāng)燈具的功率較大時，可采用石棉橡膠板或硅橡膠、氟橡膠等離火自熄的材料。還必須注意的是，在安裝玻璃透件時，就采取措施，從結(jié)構(gòu)上保證壓緊燈罩、玻璃管、透明板的周邊，受力要均勻，避免引起透明件內(nèi)部產(chǎn)生危險的機械應(yīng)力。對于隔爆型燈具的玻璃透明件，還可以采用與外殼燈體直接膠封的方法密封固定。這種結(jié)構(gòu)對膠封材料要求較高，以硅橡膠為宜。燈具透明件與外殼部件的固定，在結(jié)構(gòu)上必須保證，在更換光源時，透明件和密封件不得從外殼部件上脫落。</p><p style="text-indent:25px">防爆燈具安裝注意事項： 1、燈具傾斜安裝時，必須調(diào)整接頭與鋼管的相對位置，保證遮光板在燈泡的正上方； 2、安裝和維護燈具時，必須先切斷電源； 3、使用時,燈具表面有一定溫升，屬正?，F(xiàn)象，透明件中心溫度較高，不得觸摸； 4、必須使用本公司配備的電器； 5、更換燈泡時,應(yīng)使用同類型、功率的燈泡：如果改變燈泡類型或功率，應(yīng)相應(yīng)更換配套鎮(zhèn)流器。我們在安裝和日常使用的時候一定要小心注意一些，如果它出現(xiàn)故障，我們應(yīng)馬上請專業(yè)的維修人員來進(jìn)行維修。并且我們應(yīng)定期檢查燈具的安全度,也可以有效的保證我們使用的安全性。防爆燈具的選用、安裝、使用和維護均是保障防爆燈具長期安全、可靠、工作不可缺少的環(huán)節(jié)。</p><div

style="text-indent:25px">防爆燈具的種類比較多，主要是通過隔爆外殼，來承受燈具內(nèi)部可能產(chǎn)生的性混合物的壓力，井阻止向周圍的性混合物傳爆來達(dá)到防爆目的。隔爆型的防爆燈具，可適用電源不超過 l000V 的有白熾燈、鹵鎢燈、熒光燈泡（包括緊湊型熒光燈），高壓汞燈、高壓鈉燈、自鎮(zhèn)流高壓汞燈和金屬鹵化物燈等。其結(jié)構(gòu)特點首先是必須具備一個能承受住 GB3836．2 規(guī)定的強度試驗檢驗的隔爆外殼，這個整體的隔爆外殼，包括原則上須用金屬材料構(gòu)成的燈體部件和與此相配備的堅實的燈罩等透明件部件兩大部分。防爆燈具產(chǎn)品特性：透明燈罩采用擴散防眩目凌晶鋼化玻璃，鋼化純度高。防水防爆燈具</p><p style="text-indent:25px">按照材質(zhì)的有所不同，優(yōu)勢特征有所不同，故而防爆燈具價格不一樣。防水防爆燈具</p><p
