The invention provides an acid-resistant manhole structure for a concentrated sulfuric acid tank truck, and solves the problems that a manhole cover and a manhole seat of a manhole of an existing concentrated sulfuric acid tank truck are easy to corrode, and a sealing gasket is easy to corrode and fall off, so that the manhole loses a sealing function, is difficult to operate and the like, the manhole structure mainly comprises the manhole cover and the cylindrical manhole seat; the manhole cover is characterized in that an annular sealing groove used for installing a sealing gasket is formed in the manhole cover; the annular sealing groove is of a structure with a small opening and a large inner cavity. A sealing face, used for being in butt joint with the manhole cover, at the upper end of the cylindrical manhole seat is an arc face.

    本发明提供了一种浓硫酸罐车用耐酸人孔结构,解决了现有浓硫酸罐车的人孔存在人孔盖、人孔座易被腐蚀,密封垫易被腐蚀而脱落,从而造成人孔丧失密封功能,操作困难等问题,该人孔结构主要包括人孔盖以及筒状人孔座;其改进之处是:人孔盖上开设有用于安装密封垫圈的环形密封凹槽;环形密封凹槽为开口小且内腔室大的结构;筒状人孔座上端,用于与人孔盖对接的密封面呈圆弧面。
