Abstract

The invention provides a novel bent pipe fitting which comprises a bend and two splicing pipes. The splicing pipes are connected to the two ends of the bend through threads, the lower portions of the two splicing pipes are detachably connected with a supporting frame, a channel allowing a pipeline to pass is formed between the supporting frame and the bend, the convex upper end of the bend communicates with an external pipe, and the external pipe is in screw joint with an end cover. The novel bent pipe fitting has the following beneficial effects that the bent pipe fitting is good in stability and detachable, the bent pipe fitting is assembled and disassembled, a filtering function is achieved, impact of pipeline liquid on the convex portion of the bend can be weakened through the arranged external pipe, and the arranged supporting frame can achieve the effect of supporting the pipe fitting.

Description

technical field [0001] The invention belongs to the field of pipelines, in particular to a novel bridge-crossing elbow. Background technique [0002] Plastic pipes are widely used in the transportation of various fluids, such as various liquids, gases, etc. In some logistics-intensive areas, there are often multiple pipes criss-crossing. In order to avoid physical damage caused by mutual extrusion between crossing pipes, It is necessary to use bridge elbow fittings to erect and separate the intersecting pipes. The bridge elbow refers to the junction of water pipes and water pipes or water pipes and line pipes, and is often found at the junction of hot water pipes and cold water pipes. Existing bridge bends are usually one-time injection molding or direct bending of pipes under heating, which cannot be disassembled. [0003] One-time injection molding of the bridge elbow, the internal fluid passage of the elbow is not a smooth arc, such as a corner-shaped passage, resulting...
