Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Reference Figures 1-6 , the present invention discloses a safety type metal compensator, which includes a metal compensator main body 1 and connecting flanges 4 installed at both ends of the metal compensator main body 1. A damping spring 5 is installed on the outer surface of the metal compensator main body 1,

[0023] A support member one 2 and a support member two 3 are installed on the outer surface of the metal compensator main body 1. The support member one 2 includes two clamping blocks one 25, and the support member two 3 includes two clamping blocks two 33. The outer surfaces of the clamping blocks one 25 and the outer surfaces of the clamping blocks two 33 are fixedly connected to the outer surface of the damping spring 5;

[0024] The support member one 2 further includes a support plate one 21, a rotating rod 22, a gear 23, a transmission rack 24, and a rotating wheel 26. The support plate one 21 is fixedly installed on the outer surface of the metal compensator main body 1, and a rotating wheel 26 is movably installed inside the support plate one 21.

[0025] Further, a rotating rod 22 is fixedly installed on the outer surface of the rotating wheel 26. The outer surface of the rotating rod 22 is in movable contact with the inside of the support plate one 21, and a gear 23 is installed on the bottom surface of the rotating wheel 26.

[0026] Further, two sliding cavities are opened inside the support plate one 21. Sliding blocks are movably installed on the inner walls of the two sliding cavities. Transmission racks 24 are installed on the outer surfaces of the two sliding blocks, and the outer surfaces of the transmission racks 24 are meshed with the outer surface of the gear 23.

[0027] Further, two moving grooves are opened on the outer surface of the support plate one 21. The outer surfaces of the two sliding blocks are correspondingly in movable contact with the inner walls of the moving grooves, and the bottom surfaces of the two sliding blocks are fixedly connected to the top surfaces of the clamping blocks one 25 correspondingly.

[0028] Further, the support member two 3 further includes a support plate two 31 and a connecting column 32. A support plate two 31 is installed on the outer surface of the metal compensator main body 1, and a connecting column 32 is jointly installed on the outer surface of the support plate two 31. The outer surface of the connecting column 32 is in movable contact with the inside of the two clamping blocks two 33.

[0029] When the metal compensator body 1 and two connecting flanges 4 are used to connect pipelines for work, when external pressure or internal medium flow occurs in the pipelines and the metal compensator body 1, it will cause changes in the shape or length of the damping spring 5. Rotate the rotating wheel 26 by hand, and the rotating wheel 26 synchronously drives a number of rotating rods 22 to perform rotational motion. The rotating rods 22 increase the friction force between the rotating wheel 26 and the first support plate 21. The rotating wheel 26 stably drives the gear 23 to perform rotational motion. The gear 23 synchronously drives two transmission racks 9 to move towards each other. The two transmission racks 9 synchronously drive the sliding blocks to move in the sliding cavity. The two sliding blocks synchronously drive the first clamping block 25 to mechanically squeeze the damping spring 5, and the first clamping block 25 synchronously drives the second clamping block 33 to stably move on the connecting column 32 through the annular wire 6, and the two second clamping blocks 33 stably mechanically squeeze the damping spring 5;

[0030] Further, two annular wires 6 are jointly installed on the outer surface of the first clamping block 25 and the outer surface of the second clamping block 33.

[0031] The slight and stable mechanical squeezing of the damping spring 5 by the first clamping block 25 and the second clamping block 33 relieves the deformation of the damping spring 5, maintains the normal shape of the pipeline or the metal compensator body 1, prevents excessive deformation or failure, thereby maintaining the stability and reliability of the metal compensator body 1, and can reduce the fatigue degree of the damping spring 5, extend its service life, reduce the frequency of maintenance and replacement, reduce the operating cost of the pipeline system. Maintaining the normal shape of the damping spring 5 can ensure that the metal compensator body 1 can effectively absorb the deformation and vibration in the pipeline, prevent pipeline leakage or damage caused by the failure of the metal compensator body 1, and improve the safety of the system.

[0032] The working principle and usage process of the present utility model: When the metal compensator body 1 and two connecting flanges 4 are used to connect pipelines for work, when external pressure or internal medium flow occurs in the pipelines and the metal compensator body 1, it will cause changes in the shape or length of the damping spring 5. Rotate the rotating wheel 26 by hand, and the rotating wheel 26 synchronously drives a number of rotating rods 22 to perform rotational motion. The rotating rods 22 increase the friction force between the rotating wheel 26 and the first support plate 21. The rotating wheel 26 stably drives the gear 23 to perform rotational motion. The gear 23 synchronously drives two transmission racks 9 to move towards each other. The two transmission racks 9 synchronously drive the sliding blocks to move in the sliding cavity. The two sliding blocks synchronously drive the first clamping block 25 to mechanically squeeze the damping spring 5, and the first clamping block 25 synchronously drives the second clamping block 33 to stably move on the connecting column 32 through the annular wire 6, and the two second clamping blocks 33 stably mechanically squeeze the damping spring 5;

[0033] The slight and stable mechanical extrusion of the first clamping block 25 and the second clamping block 33 relieves the deformation of the damping spring 5, maintains the normal shape of the pipeline or the main body 1 of the metal compensator, prevents excessive deformation or failure, thereby maintaining the stability and reliability of the main body 1 of the metal compensator, and can reduce the fatigue degree of the damping spring 5, extend its service life, reduce the frequency of maintenance and replacement, reduce the operating cost of the pipeline system. Maintaining the normal shape of the damping spring 5 can ensure that the main body 1 of the metal compensator can effectively absorb the deformation and vibration in the pipeline, prevent pipeline leakage or damage caused by the failure of the main body 1 of the metal compensator, and improve the safety of the system.
