Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
U-tube heat exchanger single tube structure for pressure test of the present invention, including bottom plate fixture 1, rocking lever 2, water injection module 3, injector 4
With screwing screw rod 5, as shown in Figure 1 and Figure 2.
The bottom plate fixture 1 is with leading flank, trailing flank and the U-shape structure of bottom surface.Wherein, the front side of bottom plate fixture 1
Face is provided with rectangular aperture at center, as heat exchange tube passage.Screw screw rod 5 to set perpendicular to bottom surface, with leading flank top center
The screw thread hole connected with rectangular aperture the threaded connection of Position Design, and end and the rectangle briquetting that is placed in rectangular aperture
It is threadedly coupled between the tapped blind hole of 101 top centers design, thus screws and form lead screw transmission between screw rod 5 and rectangle briquetting 101.
Above-mentioned rectangular aperture base and the bottom center position of rectangle briquetting 101 are provided with symmetrical V-groove, realize to wait to suppress jointly and change
The fixation of heat pipe end.Thus, tube end to be suppressed is passed through by rectangular aperture, is placed in the V-groove on rectangular aperture base
Interior positioning, screw rod 5 then is screwed by rotating, rectangle briquetting 101 is moved down, makes tube end position rectangle briquetting to be suppressed
