Embodiment Construction
[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0021] The present invention needs to braze and connect 24 nozzles with gas hoods to the main and auxiliary oil pipes, and ensure that the flatness of the 24 nozzles after brazing is ≤0.3mm.
[0022] Such as figure 1 As shown, there is a pair of symmetrical shoulders 5 below the upper surface of the spout, such as figure 2 and image 3 As shown, structural part 1 is placed on the upper end surface of the spout across two shoulders. The width is 7mm, wherein the vertical side length on the outside (that is, outside the circumference of the fuel main pipe or the circumference of the annular base 2) is 12mm, and the length on the inside vertical side is 11.8mm, and the difference between the two is 0.2mm.
[0023] Such as Figure 4 As shown, 24 observation ports 3 are arranged at equa...
