Description

Technical Field

[0001] The utility model relates to the technical field of welded bellows, in particular to a welded bellows assembly with high reliability. Background Art

[0002] Welded bellows is a metal tube made by precision welding multiple stamped thin hollow diaphragms. This type of tube is highly flexible and scalable and is widely used in various industrial fields. The structure of the welded bellows consists of two formed hollow diaphragms, which are welded at the inner edges to form diaphragm pairs. Then, multiple diaphragm pairs are welded at the outer edges to form a corrugated section. The two ends are then welded to the end plate metal to form a complete bellows group.

[0003] During the use of existing welded bellows, the positioning of the bellows is completely dependent on the flanges at both ends, and the middle part lacks effective support. When the bellows are subjected to internal or external loads, especially when the bellows are long, they are prone to excessive bending deformation, which not only affects the service life of the bellows, but may also cause safety problems such as leakage or breakage.

[0008] Through the above technical solution, the middle or both ends of the bellows are supported by the support plate, so that the bellows can effectively reduce bending deformation when subjected to internal and external loads, enhance the overall stability of the bellows during use, and improve the reliability under various working conditions. By turning the handwheel, the bidirectional screw is rotated, and the mounting seats are moved closer or farther away from each other, thereby adjusting the position of the support plate, which is convenient for flexible adjustment according to bellows of different lengths.

[0009] As a further improvement of the above solution, the handwheel is located outside the fixed base, and the surface of the mounting seat is slidably connected to the inner wall of the sliding groove.

[0010] Through the above technical solution, the handwheel located on the fixed base is easy to operate during use, and the sliding groove limits the mounting base, making the mounting base more stable when moving.

[0011] As a further improvement of the above solution, there are two mounting seats, and the two mounting seats are symmetrically distributed around the fixed base.

[0012] As a further improvement of the above solution, a plurality of threaded holes adapted to fastening bolts are provided on the surfaces of the vertical plate and the connecting plate, and the inner wall of the support plate contacts the surface of the corrugated pipe.

[0013] Through the above technical solution, the vertical plate and the connecting plate are fixed by tightening bolts, and the height of the connecting plate can be adjusted according to needs through a plurality of threaded holes.

[0014] As a further improvement of the above solution, both ends of the fixed base are fixedly connected with fixed plates, and the inner wall of the fixed plate is fixedly connected with a limiting rod.

[0015] As a further improvement of the above solution, the inner wall of the limiting rod is slidably connected to a diagonal support plate, and one end of the diagonal support plate away from the limiting rod is fixedly connected to the surface of the vertical plate.

[0016] Through the above technical solution, the diagonal support plate plays a role of stable support, ensuring the stability of the vertical plate when in use. When the vertical plate moves, it will slide along the surface of the limit rod with the diagonal support plate.

[0017] As a further improvement of the above solution, the surface of the corrugated pipe is provided with a corrugated protective sleeve, and the surface of the corrugated protective sleeve is provided with a clamp.

[0018] Through the above technical solution, the corrugated protective sleeve is installed on the surface of the corrugated pipe through a clamp, which provides additional physical protection for the corrugated pipe, prevents the external environment from damaging the corrugated pipe, and extends the service life of the bellows.

[0019] Compared with the prior art, the beneficial effects of the present invention are:
