Pipeline connection structure and hydraulic pipeline

Abstract

The invention discloses a pipeline connection structure, which comprises a steel pipe (1), a connecting nut (2) clamped on the steel pipe (1), a rubber tube, a wrap (4), a joint core (3) and a matching sleeve (6). According to the pipeline connection structure provided by the invention, the matching sleeve which can be selected along with the diameter of a steel pipe is additionally arranged in the joint core, so that the joint core can be directly connected with steel pipes of different diameters, the traditional structure characterized in that connection can only be realized by a transition joint is changed, the amount of parts is reduced, connection points in the integral pipeline are reduced, and leakage accidents are reduced. Different types of matching sleeves are used for sheathing the steel pipes of the corresponding types, the types of the steel pipe which can be subjected to butt joint with the joint core are expanded, the types of connecting accessories between the steel pipe and the joint core are reduced, unnecessary resource waste caused by excessive accessories is avoided, complex work of selecting the accessories due to assembling is omitted, and the assembling time is saved. The invention also discloses a hydraulic pipeline applying the pipeline connection structure.

Description

technical field [0001] The invention relates to the field of hydraulic pipes, in particular to a pipe connection structure and a hydraulic pipe. Background technique [0002] In the hydraulic pipeline, the diameter of the steel pipe, the shape and connection method of the oil port, the selection of the hose and joint core, the selection of the transition joint, and the selection of the type of connection accessories need to be considered when assembling the hose joint. And each accessory contains multiple models, and the combination and matching of various accessories can complete the overall assembly of the rubber hose joint. Inconvenience in design, production, stocking and storage adds to overall maintenance costs. In addition, in the connection structure of the pipeline, it is usually necessary to use a transition joint to realize the matching and docking of the steel pipe and the joint core. The more connected parts, the more possible leak points, which increases the ...
