The attachment structure of convenient and swift, good sealing effect cracking furnace tube.
The object of the present invention is achieved like this：A kind of attachment structure of cracking furnace tube, it includes and cracking furnace body
The boiler tube of connection, described boiler tube is made up of several end to end male boiler tubes and the female boiler tube being engaged with male boiler tube, described
Public boiler tube outer wall on be socketed with lap joint flange, be socketed with lower lap joint flange on the outer wall of described female boiler tube, it is described
Ω ring pads are provided between upper lap joint flange and lower lap joint flange, the gap location between described male boiler tube and female boiler tube is provided with
Sealing ring.
Described upper lap joint flange is Z-type structure.
Described male boiler tube and female boiler tube are provided with the annular opening groove being engaged with Ω ring pads.
Described upper lap joint flange and lower lap joint flange are provided with the annular opening being engaged with Ω ring pads.
Beneficial effects of the present invention：The problem of technical characteristic disclosed in this invention exists for traditional structure, spy improves
Connected for globe joint male and female flange, dismounting is simple, change boiler tube conveniently, it is convenient to use, and used in sealing
Interior sealing and the collective effect of external seal seal it, have the advantages that good sealing effect, and external seal is sealed using Ω rings pad, this
Kind of sealing means are sealed using the principle of air seal, have the advantages that good sealing effect, the present invention with it is simple in construction,
Easy to use, quick and easy for installation, good sealing effect advantage.
