人(ren)(ren)(ren)孔(kong)分為緊急泄壓人(ren)(ren)(ren)孔(kong)、防爆阻火呼(hu)吸(xi)人(ren)(ren)(ren)孔(kong)、罐(guan)(guan)頂人(ren)(ren)(ren)孔(kong)、罐(guan)(guan)壁人(ren)(ren)(ren)孔(kong)和(he)帶芯人(ren)(ren)(ren)孔(kong)

人孔已有(you)成型產品，直徑通常(chang)為600mm。人孔中(zhong)心距(ju)地板一般為750mm。便(bian)于工作人員在安裝(zhuang)、清洗(xi)、維護時進出油罐或通風。

非(fei)金(jin)屬(shu)(shu)油(you)(you)罐(guan)的人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)設在(zai)罐(guan)頂(ding)上(shang)，金(jin)屬(shu)(shu)油(you)(you)罐(guan)的人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)設在(zai)罐(guan)壁***下圈板上(shang)。大都為(wei)直徑(jing)600mm的圓(yuan)孔(kong)(kong)(kong)，其(qi)中心距底板750mm，為(wei)油(you)(you)罐(guan)清洗(xi)或維修人(ren)(ren)(ren)(ren)員進(jin)(jin)出(chu)油(you)(you)罐(guan)用，又(you)稱作道門。檢修清理(li)油(you)(you)罐(guan)時(shi)刻(ke)利用人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)進(jin)(jin)行(xing)采光和(he)通風。立式油(you)(you)罐(guan)的容量在(zai)5000m3以下時(shi)設1~2個(ge)人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)，5000m3以上(shang)的設2個(ge)人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)。人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)的安裝(zhuang)應(ying)與進(jin)(jin)出(chu)油(you)(you)管線(xian)相隔(ge)不大于90°。當(dang)只設一(yi)(yi)個(ge)人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)時(shi)，應(ying)將其(qi)置于罐(guan)頂(ding)透光孔(kong)(kong)(kong)的對(dui)面;當(dang)設2個(ge)人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)時(shi)，其(qi)中一(yi)(yi)個(ge)設在(zai)透光孔(kong)(kong)(kong)的對(dui)面，另一(yi)(yi)個(ge)應(ying)至少與第 一(yi)(yi)個(ge)人(ren)(ren)(ren)(ren)孔(kong)(kong)(kong)相隔(ge)90°。

人孔應有一(yi)個(ge)設在(zai)進(jin)出油管(guan)右側附近，并盡(jin)量使人孔正對罐室密閉門，以便人員(yuan)進(jin)出、維修油罐和通風接管(guan)用。

由于人孔(kong)安裝在油罐的下層體圈(quan)上(shang)，防滲漏就顯得特(te)別(bie)重要(yao)(yao)。要(yao)(yao)求兩法蘭(lan)結合面(mian)必須保證其平直(zhi)度，無(wu)飄扭(niu)現象。加(jia)強(qiang)板(ban)和法蘭(lan)應盡量在整塊鋼(gang)板(ban)上(shang)切割而不拼(pin)接。法蘭(lan)和蓋(gai)板(ban)上(shang)加(jia)工有密封(feng)圈(quan)，在施工中要(yao)(yao)特(te)別(bie)注意保護(hu)。密封(feng)用3mm厚石棉(mian)橡膠(jiao)墊片(pian)，不允(yun)許有折裂。安裝人孔(kong)蓋(gai)板(ban)上(shang)緊螺栓時，要(yao)(yao)成對角均勻用力，以(yi)防孔(kong)蓋(gai)變形。
