I. Introduction of GTG-series light transmission holes

  设在罐顶,用于油罐安装和清洗时采光和通风,透光孔上部与通气孔连接,平时用眼圈盲板封闭。 GTG-series light-transmitting holes are set on the top of the tank for lighting and ventilation during oil tank installation and cleaning. The upper part of the light-transmitting holes is connected to the ventilation holes and is usually closed with blindfolds. When cleaning the oil tank, open the blindfold of the eye circle and connect the ventilation hole, and the tank can be mechanically ventilated.
