Anti-cold-consolidation circular pipe connecting structure

Abstract

The invention discloses an anti-cold-consolidation circular pipe connecting structure. The anti-cold-consolidation circular pipe connecting structure comprises a connector, circular pipes and clamping sleeves, wherein the connector is provided with a fluid channel, and the clamping sleeves are arranged at the two ends of the connector. The inner end faces of the two ends of the connector are conical surfaces. External threads are arranged on the outer end faces of the two ends of the connector. Each clamping sleeve is formed by welding a locking nut and a clamping device together. A gap used for allowing the end opening of the connector to be arranged therein in a sleeved mode is reserved between each locking nut and the corresponding clamping device. The sizes of the locking nuts are matched with the diameters of the outer end faces of the connector, and the locking nuts are provided with internal threads engaged with the external threads on the outer end faces of the connector. The clamping devices are arranged between the locking nuts and the connector. Pipe insertion through holes with the diameters being matched with the diameters of the circular pipes are formed in the middles of the clamping devices. Conical surfaces are further arranged at the ends, facing the connector, of the clamping devices. The axial included angles of the conical surfaces of the connector are larger than the axial included angles of the conical surfaces of the clamping devices. By the adoption of the anti-cold-consolidation circular pipe connecting structure, rapid pipe connection can be achieved.

Description

technical field [0001] The invention relates to the field of pipeline engineering, in particular to an anti-cold solidification round pipe joint structure. Background technique [0002] In the existing construction site, traditional methods are often used for water supply or other fluid pipelines, such as arranging steel wires outside the pipelines for binding and winding, or using flanges for butt welding to weld the two pipelines to death, but this operation method not only It is time-consuming and labor-intensive, and a lot of labor costs are wasted. Moreover, when the engineering process is fast, the pipeline needs to be relocated. At this time, it takes a lot of time to disassemble and reassemble the pipeline. The disassembly of the flange welding form is more troublesome, and even the cost of purchasing a new flange needs to be increased.
