Problems solved by technology

Therefore, after the connection is completed, the ductile iron pipes do not form a whole that resists lateral tension like the galvanized pipes connected by flanges or clamps, which will cause the pipe joints to come out and cause water leakage accidents.

Abstract

The invention discloses a ductile iron pipeline fixing structure, mainly comprising a first ductile iron pipeline and a second ductile iron pipeline, the joint of the first ductile iron pipeline is provided with a socket, and the joint of the second ductile iron pipeline is provided with a socket , the insertion port is inserted into the socket port, the first ductile iron pipe is provided with a first pipe holding card and a first retaining ring that fit each other, and the first retaining ring is fixed on the socket port facing the first pipe holding card One side of the second ductile iron pipe is provided with a second pipe holding card and a second retaining ring that fit together, and the second retaining ring is fixed on the side of the second pipe holding card facing the insertion port, so The first pipeline holding card and the second pipeline holding card are fixed by the fixing block. The invention has simple structure and reasonable design. The ductile iron pipeline can resist the axial tension and the transverse tension through the clamping of the first pipeline and the clamping of the second pipeline, and the displacement of the ductile iron pipeline in any direction is avoided.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a ductile iron pipeline fixing structure. Background technique [0002] Ductile iron pipe is an ideal pipe widely used in the world at present. It has the characteristics of high strength, good toughness, strong corrosion resistance, long life and convenient installation, and has unique acid, alkali, electrochemical and miscellaneous resistance. The characteristics of galvanic corrosion. Therefore, ductile iron pipes have been widely used as water delivery pipes in water supply and drainage systems. The most representative flexible interface method of ductile iron pipes is increasingly widely used in water, gas, and oil transportation projects. The conventional connection of ductile iron water pipes installed with slide-in (T-shaped) flexible joints mainly depends on the extrusion of the matching rubber rings at the pipe joints to form a whole connection. Therefore, the duct...
