The invention aims to provide a gusset plate, a Coriolis flowmeter and a method for manufacturing the gusset plate, which ensure that the gusset plate is attached to a bent section of a pipe body and reduce the manufacturing cost of the gusset plate.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. In this embodiment, the outer contour of the cross section of the pipe bending section 5 is circular, and the pipe bending section 5 is a circular pipe bending section at this time. The outer contour may be in other shapes such as an ellipse, a regular polygon, etc., depending on the actual situation.
Referring to fig. 3 to 4 and 12 to 14, the present embodiment provides a gusset plate 1, which includes a first plate 6 and a second plate 9. The first plate body 6 is provided with an inner curved surface section 7, and the inner curved surface section 7 is attached to the inner side of the pipe body bending section 5. The second plate body 9 has an outer curved surface section 10, and the outer curved surface section 10 is used for being attached to the outer side of the pipe bending section 5. The first plate body 6 is used for being fixedly connected with the second plate body 9, so that the inner curved surface section 7 and the outer curved surface section 10 respectively hold the pipe body bending section 5 from the inner side and the outer side.
In this embodiment, because first plate body 6 and second plate body 9 are laminated with body bending section 5 through interior curved surface section 7 and outer curved surface section 10 respectively, can improve hookup location's stability, avoid taking place relative slip. In addition, through dividing into first plate body 6 and second plate body 9 with gusset plate 1, can prepare first plate body 6 and second plate body 9 respectively earlier, install first plate body 6 and second plate body 9 at body bending segment 5 again, reduce the preparation degree of difficulty.
As a possible example, the first plate body 6 further has a first solder guide groove 8, the first solder guide groove 8 being arranged adjacent to the inner curved section 7, and the second plate body 9 further has a second solder guide groove 11, the second solder guide groove 11 being arranged adjacent to the outer curved section 10. When connecting first plate body 6 with pipe body bending section 5 brazing to and when connecting second plate body 9 with pipe body bending section 5 brazing, first brazing filler metal guiding groove 8 and second brazing filler metal guiding groove 11 can guide the brazing filler metal to get into the assigned position to improve the quality of brazing.
