儲罐(guan)(guan)透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)設(she)在(zai)罐(guan)(guan)頂(ding)，用(yong)于(yu)油(you)(you)罐(guan)(guan)安(an)(an)(an)裝(zhuang)和(he)清洗時(shi)采(cai)(cai)光(guang)(guang)和(he)通(tong)風。油(you)(you)罐(guan)(guan)的(de)(de)采(cai)(cai)光(guang)(guang)設(she)在(zai)罐(guan)(guan)頂(ding)上(shang)(shang)，一(yi)般為直(zhi)(zhi)接500mm的(de)(de)圓孔(kong)(kong)(kong)(kong)(kong)，平時(shi)有(you)孔(kong)(kong)(kong)(kong)(kong)蓋環以(yi)螺栓嚴密封閉。在(zai)清理檢修油(you)(you)罐(guan)(guan)時(shi)，用(yong)以(yi)采(cai)(cai)光(guang)(guang)，通(tong)風排氣。另外(wai)當保險活門(men)(men)的(de)(de)操作裝(zhuang)置失靈時(shi)，還可(ke)利用(yong)系于(yu)透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)處(chu)的(de)(de)鋼索來打開保險活門(men)(men)。當罐(guan)(guan)頂(ding)只設(she)立一(yi)個(ge)透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)時(shi)，應位于(yu)進出油(you)(you)管線(xian)上(shang)(shang)方的(de)(de)罐(guan)(guan)頂(ding)上(shang)(shang)；設(she)兩個(ge)透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)時(shi)，則透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)與(yu)人孔(kong)(kong)(kong)(kong)(kong)盡可(ke)能沿圓周(zhou)均(jun)勻分布，以(yi)利于(yu)采(cai)(cai)光(guang)(guang)和(he)通(tong)風，但至少(shao)有(you)一(yi)個(ge)透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)設(she)在(zai)罐(guan)(guan)頂(ding)平臺(tai)附近。透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)外(wai)緣應距罐(guan)(guan)壁800~1000mm.透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)上(shang)(shang)部與(yu)通(tong)氣孔(kong)(kong)(kong)(kong)(kong)連接，平時(shi)用(yong)眼圈盲板封閉。洗修油(you)(you)罐(guan)(guan)時(shi)打開眼圈盲板，接通(tong)通(tong)氣孔(kong)(kong)(kong)(kong)(kong)，罐(guan)(guan)內便(bian)可(ke)進行(xing)機(ji)械通(tong)風。 透(tou)光(guang)(guang)孔(kong)(kong)(kong)(kong)(kong)，地上(shang)(shang)式油(you)(you)罐(guan)(guan)的(de)(de)量(liang)油(you)(you)孔(kong)(kong)(kong)(kong)(kong)、阻火器、呼吸閥均(jun)組裝(zhuang)在(zai)人孔(kong)(kong)(kong)(kong)(kong)蓋上(shang)(shang)。地下埋土式油(you)(you)罐(guan)(guan)按規定不安(an)(an)(an)裝(zhuang)呼吸閥，而是在(zai)人孔(kong)(kong)(kong)(kong)(kong)蓋上(shang)(shang)安(an)(an)(an)裝(zhuang)一(yi)根伸高距地面4m以(yi)上(shang)(shang)的(de)(de)通(tong)氣管，把阻火器安(an)(an)(an)裝(zhuang)在(zai)通(tong)氣頂(ding)端，量(liang)油(you)(you)孔(kong)(kong)(kong)(kong)(kong)則直(zhi)(zhi)接安(an)(an)(an)裝(zhuang)在(zai)人孔(kong)(kong)(kong)(kong)(kong)蓋上(shang)(shang)。
透光分類：A型(xing)裝于平錐項(xiang)(xiang)罐，B型(xing)裝于拱(gong)項(xiang)(xiang)油(you)罐，C型(xing)裝于重質油(you)罐，D非標定做(zuo)。
