Embodiment 1
[0032] One of the specific implementations of the heat exchanger diaphragm seal welding seam cutting machine of the present application, the heat exchanger diaphragm sealing seam cutting machine is applied to the cutting of the heat exchanger diaphragm sealing seam 10, referring to the prior art figure 1 with figure 2 As shown, the heat exchanger includes a tube bundle 2, a tube shell 3 and a tube box 4, and the tube bundle 2 is pierced through the tube sheet 5, wherein: the tube box 4 is provided with a spherical diaphragm sealing disc 6, and the spherical diaphragm sealing disc 6 is arranged in the tube box Between the end 9 and the pipe box end cover 7; the spherical diaphragm sealing disc 6 includes a spherical membrane 61 arranged in the middle and a flat edge ring 62 arranged along the outer circumference of the spherical membrane 61; the flat edge ring 62 It is sealed with the pipe box end 9 through a sealing weld 10 ; the pipe box end 9 is fixedly connected with the p...
Embodiment 2
[0039] The second specific embodiment of the heat exchanger diaphragm seal welding seam cutting machine of the application, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment adopt the explanation in embodiment 1, No further details will be given here. The difference between this embodiment and embodiment 1 is that the reference image 3 As shown, the frame 12 is provided with an adjustment spoke 15 with a chute in the middle, and the frame 12 is fixed to the pipe box end 9 through the adjustment spoke 15 . Generally speaking, the 9 manholes at the end of the pipe box are relatively fixed and designed to vary from 500mm to 700mm. Adjusting the radial expansion and contraction of the spokes 15 can be applied to the range of change from 600mm to 800mm in the center circle of the threaded hole 91 at the end of the pipe box 9. , but the above variation range can be changed according to design requi...
Embodiment 3
[0042] The third specific embodiment of the heat exchanger diaphragm seal welding seam cutting machine of the present application, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment adopt the explanation in embodiment 1, No further details will be given here. The difference between this embodiment and Embodiment 1 is that the installation of the frame 12 and the pipe box 4 does not need to use the threaded hole 91 at the end 9 of the pipe box. Instead refer to Figure 5 As shown, the frame 12 is fastened to the pipe box outer circle 1 of the pipe box end 9 by tightening bolts 21 . If necessary, depending on the situation of the threaded holes 91, the number of tightening bolts 21 can be appropriately increased to enhance the connection rigidity.
