The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1-2, a sealing member for connecting a pressure pipeline comprises a connecting pipe body 1 and sealing rings 2, wherein two ends of the connecting pipe body 1 are conical heads, notches 11 are formed in the conical heads along the axial direction, annular grooves 12 for installing sealing rings 3 are formed in outer rings of the conical heads, a flange plate 13 is arranged in the middle of the connecting pipe body 1, two sealing rings 2 are sleeved at ports of the pipeline 100 and are respectively located at two sides of the flange plate 13, the sealing rings 2 are provided with connecting portions 21 corresponding to the flange plate 13, the connecting portions 21 of the sealing rings 2 penetrate through the flange plate 13 through long bolts to be connected, and toothed rings 22 are arranged on the inner sides of one ends, away from the flange plate 13, of the sealing rings 2. Specifically, in this embodiment, during the use, establish two sealing rings 2 cover respectively in the pipe mouth outside of pipeline 100, again with connecting pipe body 1 both ends insert the mouth of pipe of pipeline 100 in, make as hard connection, simultaneously because connecting pipe body 1 both ends are the conical head form, and set up the incision on the conical head, it is comparatively smooth and easy when making it insert, the mouth of pipe extrusion conical head of pipeline 100, because the existence of incision 11, make the conical head can shrink, ring groove 12 is equipped with in the conical head, as the mount pad of installing sealing washer 3, set up ring flange 13 in the middle part of connecting pipe body 1, ring flange 13 protrusion is outside pipeline 100, be used for being connected with sealing ring 2, specifically be connected with ring flange 13 through the bolt, and make two sealing rings 2 can be in axial direction taut. The connecting portion 21 of the sealing ring 2 is matched with the flange 13, a gasket can be arranged between the connecting portion 21 and the flange 13 for enhancing the sealing performance, meanwhile, a toothed ring 22 is arranged at one end of the sealing ring 2 far away from the flange 13, one end of the toothed ring 22 is specifically connected with the inner side of the end portion of the metal sealing ring 2 through a rotational molding process, the other end of the toothed ring 22 is exposed, the toothed ring 22 is matched with the outer side of the pipeline 100 to be connected, and the sealing is realized.
