注意事項：

    由(you)于人孔(kong)安(an)裝在(zai)油(you)罐的最下層體圈(quan)上(shang)，防(fang)滲(shen)漏就顯(xian)得特(te)別(bie)重要(yao)。要(yao)求兩法(fa)蘭(lan)結合面必(bi)須保證其平直度，無飄扭現象。加(jia)強板和法(fa)蘭(lan)應盡量(liang)在(zai)整塊鋼板上(shang)切割而不拼接。法(fa)蘭(lan)和蓋(gai)板上(shang)加(jia)工有密(mi)封圈(quan)，在(zai)施工中要(yao)特(te)別(bie)注意(yi)保護。密(mi)封用(yong)3mm厚石棉(mian)橡膠墊(dian)片，不允許有折裂。安(an)裝人孔(kong)蓋(gai)板上(shang)緊螺栓時，要(yao)成對角(jiao)均與用(yong)力(li)，以防(fang)孔(kong)蓋(gai)變形。

1、以人孔(kong)(kong)上覆承受負荷(he)能力劃分(fen)以人孔(kong)(kong)上覆承受負荷(he)能力劃分(fen)可分(fen)為汽-20級和汽-10級兩種(zhong)

2、以人孔(kong)(kong)的通(tong)(tong)向劃分可分為直通(tong)(tong)人孔(kong)(kong)、三通(tong)(tong)人孔(kong)(kong)、四通(tong)(tong)人孔(kong)(kong)和斜(xie)通(tong)(tong)人孔(kong)(kong)，具體(ti)詳見下(xia)表(biao)1。其中，斜(xie)通(tong)(tong)人孔(kong)(kong)又分為15°、30°、45°、60°、75°共五種(zhong)。每種(zhong)斜(xie)通(tong)(tong)人孔(kong)(kong)的角(jiao)度(du)，可適(shi)用于±7.5°范圍以內。
