Embodiment

[0021] Example: During installation, insert one end of the pipe 2 into the nozzle 1, then slide the connecting cap 10 to one side of the ring plate 8, and turn the connecting cap 10 to screw it on one end of the nozzle 1 through threading. If the screw is screwed in, the pipe 2 and the pressure ring 9 will be pushed to the side of the nozzle 1 through the ring plate 8, and the end of the pipe 2 will be in close contact with the rubber pad 5 on the inner wall of the expanding ring 4 to achieve a primary seal. The rubber pad 5 is The conical structure with the same shape as the expanding ring 4, at the same time, the pressure ring 9 is embedded in the annular groove 6, and the sealing ring 7 is squeezed to achieve secondary sealing, wherein the setting of the tapering ring can play a role in guiding the flow. effect;

[0022] In order to ensure that the subsequent connecting cap 10 will not be rotated due to external factors, when the connecting cap 10 is screwed, the adjustment...

Abstract

The invention discloses a self-locking sealing pipeline connecting device which comprises a connecting pipe and pipelines arranged on the two sides of the connecting pipe, convex rings are fixedly arranged on the two sides in the connecting pipe, each convex ring is composed of a gradually-shrinking ring and a gradually-expanding ring, an embedding groove is formed in the circumference of the inner wall of each gradually-expanding ring, and a rubber pad is fixedly arranged in each embedding groove. The pipeline connecting device relates to the technical field of pipeline connection and is compact in structure, the connecting cap is screwed to the connecting pipe, so that the connecting cap pushes the pipeline to abut against the rubber pad of the gradually-expanding ring, primary sealing is achieved, meanwhile, the connecting cap enables the pressing ring to be embedded into the annular groove, and therefore the sealing effect of the pipeline is improved. And due to the arrangement of the locking structure, the phenomenon that the threads are loosened due to the fact that the connecting cap rotates due to external factors can be avoided, and convenience is brought to use of people.

Description

technical field [0001] The invention relates to the technical field of aviation pipeline connection, in particular to a self-locking and sealing pipeline connection device. Background technique [0002] A pipeline is a device for conveying gas, liquid or fluid with solid particles connected by pipes, pipe joints and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the pipeline to the low pressure, and the fluid can also be transported by its own pressure or gravity. Pipes have a wide range of uses and are essential components in all types of installations. [0003] Chinese patent CN214789710U discloses a plastic pipe connection head and a pipe connection device. The pipe connection head includes a connection part, a threaded part and a holding part, and the holding part is connected between the connection part and the threaded part; the pipe in the embodiment of the present application The connec...
