Under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
As shown in Figure 1 to Figure 3, the utility model embodiment fills out function seal structure for heat exchanger, including shell 1, first
Nipple joint 3 and the second nipple joint 7, the both ends of shell 1 are welded with housing end plug 10, the inner wall and shell of housing end plug 10
1 inner wall flushes, i.e. the internal diameter of the internal diameter of housing end plug 10 and shell 1 is equal.Fuse 9 is installed in shell 1, the two of fuse 9
End is equipped with mounting base, wherein and the first end of fuse 9 can be tightly connected with housing end plug by bolt lock, and the end mounting base
Outer diameter is greater than the internal diameter of housing end plug, so that the end fuse can not pass through enclosure interior；The mounting base 91 of the second end of fuse 9
Outer diameter be less than the internal diameter of housing end plug 10,91 end of mounting base at the end is stretched out outside shell 1, and end is welded with outer diameter and is less than
The fuse end cap 2 of 10 internal diameter of housing end plug.It is set with sealing ring 11 and sealing gland 12 in the mounting base 91 of 9 second end of fuse,
And 10 outer end face of outer wall and housing end plug that sealing ring 11 makes sealing ring and mounting base 91 is squeezed by sealing gland 12
The sealing of enclosure interior is realized in fitting, and by locking member lock sealing gland 12 and housing end plug 10, locking member can be used
Bolt.
As shown in Figure 1 to Figure 3, fuse end cap 2 can be connect with the first end of the first nipple joint 3 by welding manner,
The second end of first nipple joint 3 can be connected through a screw thread mode with the first end of the second nipple joint 7 and connect, and the first spiral shell
The junction of line adapter tube 3 and the second nipple joint 7 is set with German-style metal lensring 5, and screwed flange 4 is equipped on the first nipple joint 3, the
Two nipple joints 7 are equipped with screwed flange 6, and the outer diameter of screwed flange 4 and screwed flange 6 is respectively less than the internal diameter of shell 1, thus
Enable the overall structure of fuse second end to pass through shell, is taken out from shell, to clean.Screwed flange 4 and screw thread method
6 rotation of orchid moves toward one another compression German-style metal lensring 5 and first nipple joint 3 and 7 junction of the second nipple joint is sealed, and improves sealing
Performance.The outer diameter of screwed flange 4 and screwed flange 6 is less than 1~2mm of outer diameter of fuse end cap 2, is not only contributed to using the structure
Smoothly extraction fuse, and ensure that the intensity of two screwed flanges.
As shown in Figure 1 to Figure 3, the second end of the first nipple joint 3 be equipped with the matched external screw thread of screwed flange 4, and should
Externally threaded outer diameter enables screwed flange 3 the less than the outer diameter of 3 first end of the first nipple joint using structure design
Mobile adjustment position on one nipple joint 3, but the moving range of screwed flange 3 can be limited again simultaneously, it avoids dry with other components
It relates to.The first end of second nipple joint 7 be equipped with the matched external screw thread of screwed flange 6, and the externally threaded outer diameter is less than second
The outer diameter of 7 second end of nipple joint enables screwed flange 3 is mobile on the second nipple joint 7 to adjust using structure design
Whole position, but the moving range of screwed flange 6 can be limited again simultaneously, it avoids and other component interferences.On first nipple joint 3
Connecting hole 41 is distributed with along its circumferencial direction in screwed flange 4, and the screwed flange 6 on the second nipple joint 7 is along its circumferencial direction point
