Abstract
The utility model discloses a connecting device for a large diameter pipeline. The connecting device for the large diameter pipeline comprises the large diameter pipeline and is characterized in that a sleeve is sleeved on connecting ends of every two large diameter pipelines, filler is arranged between the two large diameter pipelines, check rings with embossments are arranged at two ends of the inner wall of the sleeve, and gaps are arranged between ends with embossments of the check rings and end openings of the two large diameter pipelines. The connecting device for the large diameter pipeline is capable of effectively connecting and sealing large diameter pipelines with smooth surfaces, convenient to operate, obvious in effect, low in cost and easy to maintain.
Description
Technical field
The utility model relates to pipeline connection technology, particularly a kind of device for the large diameter pipeline connection.
Background technique
Now, the connecting means between the pipeline is a lot, wherein mainly contain be welded to connect, be threaded, flange connects, socket joint connects etc.; Wherein each connects again various technological methods.The socket joint in past connects, and is that pipeline makes joint socket, pouring into (or squeeze into, insert, clamp-on) filler after another root pipeline insertion.Filler has flax silk, rubber ring, lead, cement, plastics etc. very various.These connecting means all respectively have excellent, shortcoming.But their deficiency point is all not bery adaptations of pipeline connection to steel pipe, engineering plastics pipe etc. smooth in appearance.Usually, the connection of steel pipe, engineering plastics pipe etc. smooth in appearance pipeline adopts welding method to connect.But, in the field that does not have electricity, weld just very inconvenient; Also have, welded pipe line has to consider the welding cost problem, such as, welding heavy caliber carbon steel and stainless multiple tube, its method more complicated, cost costliness.
Summary of the invention
The purpose of this utility model provides a kind of large diameter pipeline connection set, and by cleverly sleeve structure design, effectively the large diameter pipeline with smooth in appearance connects, and easy to operate, effect is remarkable, and is with low cost, is easy to safeguard.
Concrete technological scheme:
A kind of large diameter pipeline connection set is to be made of sleeve pipe, filler.Large diameter pipeline connecting end cover has sleeve pipe in twos, sleeve pipe and be provided with in twos filler between the large diameter pipeline.The back-up ring of projection is respectively established at the internal surface of sleeve pipe two ends.Keep between back-up ring protruding end and the two large diameter pipeline ports in the gap, to make things convenient for packing into of filler, prevent that simultaneously dried filler from dropping out and affect sealing.
Establish the sleeve pipe of back-up ring in the utility model adopts, join and corresponding filler again, effectively the large diameter pipeline with smooth in appearance connects, and easy to operate, effect is remarkable, and is with low cost, is easy to safeguard.
