Detailed description of the invention
The application will be further described in conjunction with the embodiment in accompanying drawing below:
It should be understood that the jacket heat-exchanger that the application mentions can be rapid-cooling heat exchanger, this jacket heat-exchanger is made up of multiple jacket pipes, so-called jacket pipe refers to that the pipe box that overall diameter is less enters in the pipe formed inside the pipe that interior diameter is bigger to have tubular construction, the group that the application is applied in jacket heat-exchanger straight tube between pipe is right, also includes the welding of the interior pipe of straight tube and the connector at both ends。
Embodiment 1
The pipe Deep Hole Welding group detailed description of the invention to device in the jacket heat-exchanger straight tube of the application, such as Fig. 1, shown in Fig. 2 and Fig. 3, right for group between pipe in jacket heat-exchanger straight tube, device is symmetrical arranged by described group with pipe shaft centre line, device is included conduit 3 by described group, the axis of cone 2 being connected with conduit 3, sleeve 1 with the axis of cone 2 taper fit, and it is arranged at the reinforcement pad of the axis of cone 2 excircle, device is stretched in jacket heat-exchanger straight tube and manages by described group, under the effect of External Force Acting B, sleeve 1 with reinforcement pad is advanced into the piece of two adjacent inner tube the big inwall making the outer surface of reinforcement pad be close to two adjacent inner tube with more straight two adjacent inner tube with the sleeve 1 of reinforcement pad of support simultaneously by the axis of cone 2。Wherein, described reinforcement pad is equal thickness pad 5 or non-equal thickness pad 6。Equal thickness pad 5 or non-equal thickness pad 6 are bonded at the outer surface of sleeve 1, equal thickness pad 5 or non-equal thickness pad 6 can be close to greatly the inwall of two pipe fittings along with the support of sleeve 1, make to exist between the inwall of two pipe fittings and sleeve 1 specific gap, required inner surface weld reinforcement A can be formed after two pipe fittings welds。After welding completes, External Force Acting knocks gently and rear pull catheter 3 can make the axis of cone 2 and the sleeve 1 with reinforcement pad get loose, to extract out outside pipe fitting。
Separately, reinforcement pad is the material different with pipe fitting, and the thickness of reinforcement pad can adjust。
Concrete, one end that the described axis of cone 2 connects with described conduit 3 is big end, and the described axis of cone 2 is small end away from one end of described conduit 3, and the internal taper of the external taper of the described axis of cone 2 and described sleeve 1 matches。The setting of the axis of cone 2 so that the axis of cone 2 is by sleeve 1 supports after external force big and more straight two pipe fittings be close to two pipe fittings inwall, inner surface staggered edge free automatically。
Concrete, the outer circumferential side of described conduit 3 is provided with location-plate 4。Adopt location-plate 4 and easy to connect group of operation to device of conduit 3, and play fixed supported effect, also act as auxiliary concentricity simultaneously and assist the staggered edge free ensureing two pipe fittings。Preferably, described location-plate 4 is plectane or rolling bearing。
Concrete, the described axis of cone 2 is the axis of cone 2 that solid round steel is formed or the axis of cone 2 rolled into for cored slab。
Concrete, the described axis of cone 2 along jacket heat-exchanger straight tube pipe axially offer cross-perforating, described cross-perforating connects with described conduit 3, the described axis of cone 2 radial direction of pipe along jacket heat-exchanger straight tube offers the radial perforation connected with described cross-perforating, and described radial perforation connects with the radial perforation of described sleeve 1 and just piece to two adjacent inner tube。When high-alloy steel or low-alloy steel welding, required protective gas can pass into from conduit 3, through the cross-perforating of the axis of cone 2, radial perforation and and sleeve 1 on radial perforation out just root to piece, and effectively protect welding。
The material that sleeve 1 is different with pipe fitting is made, and sleeve 1 forms a cylinder concordant with pipe fitting inner wall。When making two pipe fittings piece in flat-position welding termination process, by gravity and Arc effect so that the metal drop of decline is propped up by sleeve 1 entirely, and reinforcement weld seam cannot be formed at interior seam surface, fundamentally solve inseam reinforcement problem。
Embodiment 2
The detailed description of the invention of the jacket heat-exchanger of the application, including the sleeve-type heat exchanging pipe being made up of inner and outer tubes, wherein, by pipe Deep Hole Welding group in the jacket heat-exchanger straight tube described in above-described embodiment 1, device welding is connected between pipe in the straight tube of described jacket heat-exchanger。The features such as it is good that the jacket heat-exchanger after adopting this group that device is grouping welding has welding quality, and packaging efficiency is high, long service life。
Finally should be noted that; above example is only in order to illustrate the technical scheme of the application; but not the restriction to the application protection domain; although having made to explain to the application with reference to preferred embodiment; it will be understood by those within the art that; the technical scheme of the application can be modified or equivalent replacement, without deviating from the spirit and scope of technical scheme。
