Detailed Description
The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.
The embodiment is shown in fig. 1 to 5, and a flange type joint includes an outer joint 2 and an inner joint 1 connected by a bolt 3, where the outer joint 2 includes an outer flange 201, the end surface of the outer flange 201 is provided with a plurality of positioning sleeves 204, the center position of the outer flange is further provided with an outer cone boss 203, the inner joint 1 includes an inner flange 101, the end surface of the inner flange 101 is provided with a plurality of step holes 106, the center position of the inner flange is further provided with an inner cone groove 103, the step holes 106 can be matched with the positioning sleeves 204, the inner cone groove 103 can be matched with the outer cone boss 203, the bottom end of the inner cone groove 103 is provided with a positioning clamp groove 104, a seal ring 4 can be installed in the positioning clamp groove 104, and the seal ring 4 can be matched with the end surface of the outer cone boss 203.
