重(zhong)力式防(fang)爆門宜采(cai)用(yong)圓(yuan)形(xing)或矩形(xing)結構(gou)(gou)，動(dong)作(zuo)壓力根據(ju)使用(yong)場景不(bu)同而有所差異，萊蕪重(zhong)力防(fang)爆門，用(yong)于(yu)(yu)(yu)煤粉倉(cang)的按1kPa動(dong)作(zuo)壓力設計，用(yong)于(yu)(yu)(yu)煙道的按不(bu)小于(yu)(yu)(yu)2kPa動(dong)作(zuo)壓力設計。門板與(yu)底座間應有良好的密(mi)封(feng)結合面，以防(fang)止(zhi)泄漏。密(mi)封(feng)條(tiao)應為(wei)彈性阻燃材料，密(mi)封(feng)結構(gou)(gou)便于(yu)(yu)(yu)拆(chai)卸更換。此外，轉動(dong)機(ji)構(gou)(gou)應為(wei)摩擦力小、不(bu)生銹、無油潤(run)滑的結構(gou)(gou)。在門板旋啟90度左右的位(wei)置上應設置靠背架，防(fang)止(zhi)門板大角度翻轉時損壞轉動(dong)機(ji)構(gou)(gou)
