Nodular cast iron pipeline fixing structure

Abstract

The invention discloses a nodular cast iron pipeline fixing structure. The nodular cast iron pipeline fixing structure mainly comprises a first nodular cast iron pipeline and a second nodular cast iron pipeline. A connection bearing port is formed in a first nodular cast iron pipeline connector, an inserting and connecting port is formed in a second nodular cast iron pipeline connector, and the inserting and connecting port is inserted in the connecting bearing port. The first nodular cast iron pipeline is provided with a first pipeline clamp and a first check ring which are mutually attached.The first check ring is fixed to the side, facing the connecting bearing port, of the first pipeline clamp. The second nodular cast iron pipeline is provided with a second pipeline clamp and a secondcheck ring which are mutually attached, the second check ring is fixed to the side, facing the inserting and connecting port, of the second pipeline clamp. The first pipeline clamp and the second pipeline clamp are fixed through a fixing block. The nodular cast iron pipeline fixing structure is simple and reasonable in design, the nodular cast iron pipelines can resist axial pull force and transverse pull force through the first pipeline clamp and the second pipeline clamp, and displacement of the nodular cast iron pipelines 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...

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.
