The inner surface of the lower fastener and the inner surface of the upper fastener are in a semi-circular shape, the tee junction assembly suitable for lining fusion welding is characterized in that the left end and the right end of the inner surface of the lower fastener and the left end and the right end of the inner surface of the upper fastener are respectively provided with a protruding structure, a groove is formed in the outer surface of one end of each straight pipe, a protruding edge is arranged at the other end of each straight pipe, a round hole is formed in the upper fastener, a step is arranged on the edge of the round hole, the protruding structures at the left end and the right end of the inner surface of the lower fastener and the left end and the right end of the inner surface of the upper fastener are respectively buckled with one straight pipe, one straight pipe is welded on the step on the edge of the round hole of the upper fastener, and the lower fastener is connected with the upper fastener in a welding mode. The tee junction assembly suitable for lining fusion welding has the advantage of facilitating replacement of flanges of different sizes according to demands at a construction site.
Description
Technical field
The utility model belongs to the pipe fitting connection part, specifically a kind of three-way connecting module that is applicable to the liner welding.
Background technique
Existing anti-corrosion pipeline is in order to meet anticorrosion and requirement of strength, the composite structure of the plastic material of employing inside lining anti-corrosive better performances and the steel pipe of outside higher-strength, the steel pipe of this composite corrosion-resistant pipe and flange part adopt welding, during connection, adopt two flanged surfaces relatively to connect.The tee pipe fitting that industrial conveying pipe arrangement is used is mostly casting, is not easy to the replacing of different flange size.
Summary of the invention
The purpose of this utility model is the defect for prior art, proposes a kind of three-way connecting module that is applicable to the liner welding of being convenient to change the different size flange.
The purpose of this utility model is achieved in that a kind of three-way connecting module that is applicable to the liner welding of the present utility model, it comprises three straight tubes, three flanges, lower fastener and upper fastener, the internal surface semicircular in shape of above-mentioned lower fastener and upper fastener, there is respectively protruding structure at the two ends, left and right that it is characterized in that the internal surface of lower fastener and upper fastener, one end outer surface of straight tube is fluted, the other end of straight tube has convex edge, circular hole is arranged on upper fastener, there is step at the circular hole edge, the protruding structure at the two ends, left and right of the internal surface of lower fastener and upper fastener is straight tube of snapping respectively, straight tube of welding on the step at circular hole edge on upper fastener, lower fastener and upper fastener are welded to connect.
A kind of three-way connecting module that is applicable to the liner welding of the present utility model, the mode of employing assembly welding, can adopt the flange of different size to carry out assembly welding.Therefore, the utlity model has and be convenient at the construction field (site), change as required the characteristics of different size flange.
