Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] figure 1 It is a structural diagram of the pipeline connection device of the present invention.

[0021] Such as figure 1 As shown, the ports at both ends of the pipe 101 are bell mouth structures, the inner side of the port at one end is lined with a sealing ring female port 102 , and the inner side of the port at the other end is lined with a sealing ring mouth 103 . The sealing ring female port 102 and the sealing ring sub port 103 are engaged with each...

Abstract

The invention discloses a pipe connecting device and solves the problems that existing liquid or slurry delivery pipes connected by welding are difficult to repair and change, and service environments of the liquid or slurry delivery pipes are limited. The pipe connecting device comprises pipe openings in flared structures at two ends of a pipe, a seal ring primary opening and a seal ring secondary opening, two half clamps and flanges. The seal ring primary opening and the seal ring secondary opening meshing with each other are arranged inside the two openings at two ends of the pipe respectively. The two half clamps are sleeved to the pipe openings, each clamp is provide with an outer flared structure corresponding to one pipe opening. A connecting plate is fixed at an inner opening of each clamp, and the two connecting plates are connected through bolts. The diameter of the flanges sleeved on the clamps is smaller than outside diameter of the clamps and larger than inside diameter of the clamps. The pipe connecting device is solid and durable, is capable of delivering high pressure liquid or slurry heavier than 100kg, is free of weld seams on the inner wall and outer wall and is convenient for connecting, and the service environments are unrestricted.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a pipeline connection device. Background technique [0002] The current connection between liquid or slurry pipelines is mostly direct welding. The disadvantage of direct welding of pipelines is that it is difficult to maintain and replace; or the flanges are welded and then connected by movable flanges, and the pipelines connected after welding with flanges , the use environment is limited, such as the situation of floating on the water surface, the problem of joint fracture is prone to occur, and, because the welded flange is produced by injection molding, the cost is high and it is not wear-resistant. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing liquid or slurry conveying pipes are connected by welding, so maintenance and replacement are difficult, and the use environment is limited. [0004] In order ...
