The invention discloses a lip-seal clamping and pressing type pipe fitting connector and an installation process of the lip-seal clamping and pressing type pipe fitting connector. The lip-seal clamping and pressing type pipe fitting connector comprises a pipe fitting, a pipe and a seal ring, wherein the pipe fitting is provided with a bell mouth, the pipe is inserted in the bell mouth of the pipe fitting, the seal ring is located between the inner side wall of the bell mouth of the pipe fitting and the outer side wall of the portion, where the pipe is inserted, of the bell mouth, and the seal ring is provided with a main ring and a ring lip. The ring lip of the seal ring is of a cylindrical cone shape, and the included angle between the ring lip and the axial direction of the pipe is 0-89 degrees. The ring lip of the seal ring is attached to the outer wall of the pipe, and a seal and stretching quantity ratio of 10-35 percent is kept. The outer diameter of the main ring of the seal ring is attached to an inner annular groove of an outwards-protruding ring of the pipe fitting, and sealing compression is kept. The lip-seal clamping and pressing type pipe fitting connector and the installation process of the lip-seal clamping and pressing type pipe fitting connector have the advantages which are unavailable in the prior art that the lip-seal clamping and pressing type pipe fitting connector is simple in structure, good in sealing performance, long in service life and the like.
Description
technical field [0001] The invention relates to the field of pipeline installation, in particular to a lip seal pressing type pipe fitting joint and an installation process thereof. Background technique [0002] Water pipeline engineering, the pipe connection interface of gas pipeline engineering, food pipeline and other projects, the existing clamping type pipeline connection technology, all adopt the structural technology of compressing elastic seals, the jaws of the clamping tool The structural technology is also manufactured to meet the sealing matching of the clamping elastic seal. The clamping jaw must not only meet the technical requirements for the compression ratio of the seal, but also meet the requirement that the clamping connection will not be pulled out or loosened. The technical requirements for locking and clamping, the difficulty in manufacturing the jaws, and the high requirements for the clamping force. The serious defect of the existing technical process ...
