Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a water conservancy pipeline quick connector. Background Art

[0002] When laying and installing existing water conservancy pipelines, they are usually carried to the construction site using hoists or manually. Then the pipelines are connected section by section, and the two sections of pipeline flanges are fastened and connected to form an integral structure using bolts. However, the sizes of municipal water conservancy pipelines are relatively large. When aligning the two sections of pipelines, it is necessary to move the pipe bodies on both sides multiple times to make the two sections of pipelines concentric and align the flange end faces. The whole process is very time-consuming. At the same time, the nuts and bolts are inconvenient to disassemble and assemble, which increases working time and reduces work efficiency. Therefore, a water conservancy pipeline quick connector is designed to solve the above problems. Utility Model Content

In the process of continuously screwing the fastening bolts, the clamping oblique block squeezes the flanges of the two sections of the pipe into alignment and seals under the action of the two edges of the trapezoidal groove;

[0007] Preferably, the opening and closing angle of the first shrink ring and the second shrink ring is a, wherein 270°≥a≥0°;

[0008] The beneficial effects of the utility model are: 1. During the shrinking and clamping process of the first shrinking ring and the second shrinking ring, the driving part at the bottom end of the clamping oblique block touches the pipe body, so that the clamping oblique block is pushed into the trapezoidal groove. Under the action of the two sides of the trapezoidal groove, the clamping oblique block squeezes and aligns the flanges of the two sections of the pipe and seals them; 2. By screwing together the fastening bolts of the U-shaped fixing mouth, the first shrinking ring and the second shrinking ring are shrunk and clamped, thereby completing the alignment and sealing of the two sections of the pipe. The whole process is very simple. BRIEF DESCRIPTION OF THE DRAWINGS
