Abstract

The invention relates to the technical field of expansion joints, in particular to a universal angle hinge type expansion joint, which comprises a corrugated pipe, a left connecting pipe, a right connecting pipe and a pin shaft assembly, wherein the left connecting pipe and the right connecting pipe are arranged at the left and right ends of the corrugated pipe; the pin shaft assembly comprises a vertical plate, hinge plates, a pin shaft and a universal ring; the vertical plate is fixed on the left connecting pipe; the universal ring is fixed on the corrugated pipe; the vertical plate is fixedly connected with the universal ring through the hinge plates; the hinge plates are arranged on both sides of the corrugated pipe; the hinge plates are fixed together with the universal ring through the pin shaft; and a slide block is connected with the universal ring and the right connecting pipe. Due to the adoption of the universal angle hinge type expansion joint, axial compensation and angular compensation can be performed at the same time, multi-direction displacement compensation requirement on a pipeline is met, the working reliability and availability of the expansion joint are enhanced, and the service lives of equipment and a system are prolonged effectively; and the universal angle hinge type expansion joint is widely applied to inlets and outlets of central air conditioner pumps, high-rise building fire pumps and water supply pumps.

Description

technical field [0001] The invention relates to the technical field of expansion joints, in particular to a universal angle hinge type expansion joint. Background technique [0002] As we all know, when the pipeline is affected by various factors such as temperature changes or geological changes, and the pipeline is damaged by various displacements, the bellows expansion joint that compensates for the pipeline is used, but the compensation function can be divided into only axial compensation. Bellows expansion joints or bellows expansion joints with angular compensation only. Therefore, when the pipeline is expanded or compressed, the existing bellows expansion joint cannot make axial or angular compensation at the same time, thus reducing the service performance. Contents of the invention [0003] The object of the present invention is to provide a universal angle hinge type expansion joint with reasonable design, simple structure, which can be used for both axial compen...
