The invention relates to a flexible pipe fitting. The pipe fitting comprises a pipe fitting body with at least one end provided with an outer thread and further comprises a threaded cap matched with the outer thread. A bevel structure is arranged at the front end of the outer thread, and annular tooth profiles are arranged on the bevel structure. The pipe fitting further comprises a clamping ring, and an inner bevel structure is arranged on an annular boss of a clamping ring head and provided with annular grooves. The annular grooves and the annular tooth profiles are matched to fasten and seal the expanded pipe fitting. Inner holes in the positions of the annular profiles are not smaller than an inner hole of the pipe fitting. A pushing gasket and an elastic dish gasket are arranged between the threaded cap and the annular boss of the clamping ring. According to the pipe fitting of the structure, the full-drift-diameter connection is achieved, the bevel structure and the pipe fitting are matched closely and smoothly, and flow resistance is reduced; meanwhile, the breeding space of legionella can be reduced, pipeline connection is safe and reliable, construction is convenient, and market popularization value is achieved.
Description
technical field [0001] The invention relates to the field of building pipelines, in particular to a pipe fitting for flexible pipes. Background technique [0002] With the development of construction pipeline technology, flexible pipe has gradually become the mainstream pipe material in the market due to its advantages of convenient production and transportation, flexible construction, wide application fields and low installation cost. At present, the mainstream flexible pipes include aluminum-plastic composite pipes, PE-X pipes, PE-RT pipes, PB pipes, and PE pipes. There are many connection methods for this type of pipes, including clamp connection. Typical existing technologies such as "A Clamp Plastic Pipe Fitting for Aluminum-plastic Composite Pipes" with the authorized announcement number CN 2510708Y; "The Inserting Structure of Hot-melt Pipe Fittings and PPR Pipes"; Sliding and Tight Connections, such as "The Connection Structure of Plastic Pipes" in CN 2620158Y. In ...
