  密閉門有(you)防(fang)水性和(he)(he)防(fang)護(hu)性，那(nei)么防(fang)水密(mi)閉(bi)門和(he)(he)防(fang)護(hu)密(mi)閉(bi)門有(you)什(shen)么不同呢？

    一、防水密(mi)(mi)閉(bi)門(men)(men)用(yong)于(yu)井(jing)下主(zhu)(zhu)變電所和(he)主(zhu)(zhu)排水泵房通往(wang)井(jing)底車(che)場的通道內，容易關閉(bi)，以防止水的突然浸入。本密(mi)(mi)閉(bi)門(men)(men)門(men)(men)扇為平鋼板、井(jing)字(zi)筋板、圈梁(liang)等組焊而成。門(men)(men)框(kuang)為槽鋼、工字(zi)鋼組合框(kuang)架結(jie)構。拉緊(jin)裝置為楔形(xing)滑塊楔緊(jin)。門(men)(men)樞(shu)采用(yong)滾動(dong)軸承支撐(cheng)。密(mi)(mi)閉(bi)門(men)(men)是一種能增加氣密(mi)(mi)性的門(men)(men)。密(mi)(mi)閉(bi)門(men)(men)的材料有(you)木(mu)質、鋼質的。關鍵部件是密(mi)(mi)封裝置。

    二、防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)設(she)置在出入(ru)口最(zui)外側(ce)，具(ju)有阻(zu)擋沖(chong)(chong)擊波(bo)(bo)和隔絕毒(du)劑兩種功(gong)能。防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)應能阻(zu)擋沖(chong)(chong)擊波(bo)(bo)，滿足(zu)相(xiang)應的抗(kang)力要求。選用時，不僅應滿足(zu)洞口尺寸的需要，還應滿足(zu)設(she)計壓力要求。鋼結構門(men)雖然價格較(jiao)高(gao)，防(fang)(fang)早期核(he)輻射性能也較(jiao)差，但因其自重較(jiao)輕，啟閉(bi)(bi)靈活，故通常用于(yu)尺寸相(xiang)對較(jiao)大的車輛(liang)出入(ru)口。防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)有很多(duo)分類，如人(ren)防(fang)(fang)防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)、鋼制防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)、鋼筋混凝土(tu)防(fang)(fang)護(hu)密(mi)閉(bi)(bi)門(men)。
