Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a multidirectional metal expansion joint of high temperature, including ring flange 1, 1 fixed connection's of ring flange connecting pipe 2, fixed connection's bellows 3 between the connecting pipe 2, the cover is equipped with carriage 4 on the bellows 3, it presss from both sides 5 through a pair of curved pipe of bolt fixedly connected with on the connecting pipe 2, the welding has backup pad 7 and channel-section steel 8 on the pipe clamp 5, channel-section steel 8, connecting piece 9 and 4 swing joint of carriage through the bolt joint on the backup pad 7, channel-section steel 8 makes the stable fixing in backup pad 7 of connecting piece 9, the bolt joint has the cushion 10 with 4 butts of carriage on the connecting piece 9, cushion 10 plays the effect of the turned angle of restriction connecting piece 9.
Specifically, as shown in fig. 1, the support frame 4 is located in the middle of the corrugated tube 3, the support frame 4 is a metal frame in a regular quadrilateral shape, and the corrugated tube 3 has a certain contraction capacity.
Specifically, as shown in fig. 2, the connecting members 9 are riveted to the upper and lower end frames of the support frame 4, and the connecting members 9 are parallel to the axial lines of the connecting pipe 2 and the corrugated pipe 3.
Specifically, as shown in fig. 1, the middle parts of the side frames at both sides of the supporting frame 4 are riveted with the connecting pieces 9, the connecting pieces 9 are parallel to the axial lines of the connecting pipe 2 and the corrugated pipe 3, and a pair of connecting pieces 9 in different rotating directions are respectively arranged at both sides of the supporting frame 4, so that the expansion joint has a universal function after being installed on the pipeline.
