Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model is achieved through the following technical solutions:
As shown in Figure 2, the utility model cancels Floating Head Flange and the hook circle of floating tubesheet end, arranges take over and pass the new structure of housing at bobbin carriage end socket.Floating tubesheet 1 adopts N-type tube plate structure (N-type tube sheet is a kind of pattern of tube plate structure in GB151), direct and cylindrical shell pipe nipple 2 is welded to connect, cylindrical shell pipe nipple 2 is that a bit of cylindrical structure (can be caused stress large if tube sheet and end socket directly weld, be connected, play the effect slowing down stress by cylindrical shell pipe nipple 2.), cylindrical shell pipe nipple 2 and spherical seal head 3 are directly welded to connect, cancel flange bolt to connect, adapter 4 and end socket 3 are directly welded to connect, reduce sealing surface, expansion joint 5 is arranged in shell-side outlet adapter simultaneously, namely shell side is arranged on outer so that install and maintenance, the connection of pipe, shell side adopts novel structural clamp plate 7, is bolted, is connected at shell side by bolt with shell side companion flange 8 and 9 at tube side and flange 6.Convenient installation and maintenance, be especially applicable to tube side temperature simultaneously, pressure be higher, the operating condition that shell side pressure is lower.
Shell side in the utility model is divided into two parts, and a part is shell-side cylinder 10, and another part is outer skull 13, more convenient like this dismounting and cleaning shell side.Wherein shell-side cylinder 10 is columnar structured, outer skull 13 comprises outer skull flange 12, cylindrical shell 13, end socket 14 and shell-side outlet adapter 15, shell flange 11 is provided with at the end face of shell-side cylinder 10, with bolts by flange 11 and outer skull flange 12 between shell-side cylinder 10 and outer skull 13.The shell-side outlet adapter 15 that end socket 14 connects is shell-side outlet.
As shown in Figure 3, adopt novel structural clamp plate 7 in the connection of pipe, shell side, grip block 7 is be clamped and connected by flange 8 and flange 9 with the connection of shell side.Grip block 7 is by being connected with flange 6 bolt with the connection of tube side.Flange 8 and flange 9 are companion flanges, for connecting grip block 7, realize the connection function of tube side outlet and shell-side outlet.Also gasket seal is housed between grip block and 6,8,9.Flange 8 and shell-side outlet are taken over and are welded to connect, and flange 9 and reduced pipe are welded to connect.
One end and the end socket 3 center drilling place of adapter 4 are welded to connect, and the other end and flange 6 are directly welded to connect, and expansion joint 5 is arranged in shell-side outlet adapter, and expansion joint is ordinary construction, and the position just arranged is in the convenient installation of shell side and maintenance.Expansion joint is directly welded in shell-side outlet adapter.This structure saves material, reduces leakage point, and (because expansion joint is placed on shell-side outlet, if be placed on tube side discharge connection 4, the diameter of inevitable shell-side outlet adapter 15 can increase the opening diameter covered outside reducing.), expansion joint is arranged on the upper convenient installation of shell-side outlet adapter and maintenance, and expansion joint only bears shell side pressure simultaneously.This structure saves material, reduces sealing surface, conveniently in the adapter that expansion joint is arranged on shell-side outlet installs and maintenance, is particularly suitable for tube side pressure high, the operating mode that shell side pressure is low simultaneously.
As shown in Figure 4, be the disc-shaped structure of central aperture, at disk border, place has groove to the structure of grip block 7, being convenient to flange 8,9 and clamping, grip block 7 having screw, for being bolted with flange 6.
Described shell-side cylinder 10 has shell side import and shell-side outlet, and shell-side fluid flows through whole housing after entering from shell side import, returns from grip block 7, finally flows out from shell-side outlet.Tube side fluid flows into from reduced pipe, enters in heat exchanger tube through grip block 7 and floating tubesheet 1, finally flows out from tube side outlet.
Technique scheme is a kind of embodiment of the present utility model, for those skilled in the art, on the basis that the utility model discloses principle, be easy to make various types of improvement or distortion, and the structure be not limited only to described by the above-mentioned specific embodiment of the utility model, therefore previously described just preferred, and not there is restrictive meaning.
