Embodiment Construction

[0011] The present invention will be described in detail below with reference to the drawings and embodiments.

[0012] Such as figure 1 As shown, the present invention includes a corrugated pipe 1 with open ends, and two ends of the corrugated pipe 1 are respectively fastened and connected to an end pipe 2, 3 communicating with the corrugated pipe 1. A first bracket 4 is fastened to the end tube 2, and a second bracket 5 opposite to the first bracket 4 is fastened to the end tube 3. A hinge mechanism 6 is jointly supported between the first bracket 4 and the second bracket 5. The hinge mechanism 6 includes a hinge plate 62 with one end rotatably connected with the first bracket 4 and a hinge plate 61 with one end rotatably connected with the second bracket 5, and the other end of the hinge plate 62 is hinged with the other end of the hinge plate 61.

[0013] In the above embodiment, such as figure 2 As shown, one end of the hinge plate 62 can be rotatably connected to the first...

Abstract

The invention relates to a universal hinge type bellow expansion joint. The bellow expansion joint is characterized by comprising a bellows, one end of the bellows is tightly connected with a first end pipe, the other end of the bellows is tightly connected with a second end pipe, a first support is tightly connected on the first end pipe, and a second support opposite to the first support is tightly connected on the second end pipe; a hinge mechanism is supported between the first support and the second support and comprises a first hinge plate with one end rotationally connected with the first support and a second hinge plate with one end rotationally connected with the second support, and the other end of the first hinge plate is hinged with the other end of the second hinge plate. The supports are tightly connected on the two end pipes respectively, the hinge mechanism is supported between the two supports, the two hinge plates of the hinge mechanism are rotationally connected with the two supports, the two hinge plates are mutually hinged, and accordingly, transverse and bending deformation of the bellows can be controlled simultaneously, and deflection displacement of a Z-type special pipe system is compensated.

Description

Technical field [0001] The invention relates to an expansion joint, in particular to a universal hinge type corrugated expansion joint. Background technique [0002] Commonly used expansion joints include axial expansion joints, planar hinge expansion joints, universal hinge expansion joints, curved pipe pressure balanced expansion joints and tie rod expansion joints. Among them, the universal hinge type expansion joint can not only withstand certain internal pressure and external pressure, but also absorb the angular displacement caused by the thermal expansion of the pipeline, and has a certain shock resistance and shock resistance. It is widely used in large blast furnaces, hot blast stoves, thermal power plants, etc. field. The main function of the universal hinge type expansion joint is the flexible element composed of the hinge plate and the universal ring. However, due to the provision of the universal ring, the overall size and weight of the universal hinge type expansio...
