MODULAR DEVICE FOR CONNECTION multilayer pipe welding tool fittings, adapters and welding tools welding equipment ADAPTER

摘要

The utility model relates to a compound of the multilayer composite pipe and the electrofusion method of diffusion welding by means of manual welders and welding machines. A modular device for connecting at least two end portions of multilayer pipes, or at least one end portion of the multilayer pipe with at least one end portion of a single-layer pipe, or one functional unit piping system made of a polymer by injection molding, or molding, It represents at least one fitting comprising at least two standardized connecting elements disposed on the end portions of the fitting, and at least two daptera, each of which is designed as a monolithic or composite or assembly element, and one part, the response to the coupling member is attached to the fitting, and its other part via fixing means to the end portion of the multilayer pipe, or the end portion of a single-layer pipe, or functional device pipeline system, or other fittings or other adapters. Together with the module structure is used: welding the fitting tool with the heating head interior and exterior surfaces, welding adapter tool with the heating head pipe and the surface of the annular slot fastening assembly adapter, the welding tool adapter comprising mounted on the handle shaft, and fixed on the handle or rod lock adapter. The technical result - improving quality connection reliability of multilayer composite tubes, reducing the risk of reduction of the flow cross section at their connection, expanding the range of application of the device, reducing the necessary range of devices for connecting multilayer pipes. 99 ZP f-ly, 17 yl.
