Pipe fitting connecting piece
The invention relates to the technical field of pipe fitting connection, and discloses a pipe fitting connecting piece which comprises a fixed pipe fitting, a sealing ring and a locking ring. According to the device, sealing of the connecting position of the pipe fitting is achieved through mutual matching of the sealing ring and the fixed pipe fitting, then the sealing ring and the fixed pipe fitting are further locked through the second protrusion on the locking ring and the first protrusion on the fixed pipe fitting, secondary locking is achieved, and due to the fact that the sealing ribs are arranged on the inner side wall and the outer side wall of the sealing ring, the sealing effect is good. The sealing ribs extend downwards in an inclined mode, so that when the shape change trend occurs at the pipeline connecting position due to overlarge pressure or overheat expansion, the sealing ribs enable sealing fastening force to be larger and larger under the pressure effect, the shape change trend can be effectively restrained, shape change is prevented, and the service life is prolonged. And a better sealing effect can be achieved.
本发明涉及管件连接技术领域，公开了一种管件连接件，包括：固定管件、密封环和锁紧环；该装置先通过密封环与固定管件相互配合实现对管件连接处的密封，再通过锁紧环上的第二凸起与固定管件上的第一凸起，进一步地锁紧密封环与固定管件，实现二次锁紧，并且因密封环的内外侧壁均设有密封棱条，且密封棱条倾斜向下延伸，因此当管道连接处因压力过大或者过热膨胀出现形状变化趋势时，密封棱条在压力作用下会使密封紧固力越来越大，能够有效抑制这种形状变化的趋势，防止形状出现变化以延长使用寿命，并且还能够起到更好的密封效果。
