Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
A kind of pipeline of floating-head heat exchanger beam shell side structure for pressure test, including stuffing-box, filler pressing and O shape rubber seal；
The side of stuffing-box and the outer skull side flange of movable tube sheets heat exchanger are tightly connected, and floating tube sheet 9 is arranged in filler
In the stuffing-box shell ring 15 of culvert, filler pressing includes filler pressing shell ring 7, and filler pressing shell ring 7 is located in stuffing-box shell ring 15
One end be resisted against 9 sealing surface of floating tube sheet, the other end of filler pressing shell ring 7 is connect with stuffing-box.
The both ends of stuffing-box shell ring 15 are respectively equipped with the first stuffing-box flange 3 and the second stuffing-box flange 5, the first stuffing-box
The size of the outer skull side flange 2 of the size and movable tube sheets heat exchanger of flange 3 matches, and is bolted.
The first sealing structure is equipped between first stuffing-box flange 3 and outer skull side flange 2；First sealing structure includes opening
It is located at the annular groove 16 of the first stuffing-box flange 3, is equipped with the first sealing ring 4,7 outer wall of filler pressing shell ring in annular groove 16
It is matched with 15 inner wall of stuffing-box shell ring, filler pressing shell ring 7 is located at one end except stuffing-box shell ring 15 equipped with filler pressing
Flange 6, filler pressing flange 6 and the size of the second stuffing-box flange 5 match, and are bolted.
Second seals structure is equipped between filler pressing shell ring 7 and floating tube sheet 9, second seals structure includes that setting is being filled out
Second between the outer groove 17 and outer groove 17 and floating tube sheet 9 of one end that material pressing ring shell ring 7 is resisted against floating tube sheet 9 is close
Seal 8, the range of degrees of outer groove 17 are 13 ° to 18 °, and the present embodiment is preferably 15 °.
Fig. 1 is that pipeline of floating-head heat exchanger beam shell side structure for pressure test scene of the present invention uses installation diagram.
Fixed tube sheet 11+ heat exchanger tube 13+ floating tube sheet 9 constitutes pipeline of floating-head heat exchanger beam, pipeline of floating-head heat exchanger beam system
Make and still uses original pressing ring 10+ gasket 12+ bolt, spiral shell in 11 side of fixed tube sheet when shell side pressure test leak-detecting in maintenance process
The structural shape of mother's fastening, pressing ring 10 is connected with the bobbin carriage side flange 14 of heat exchanger cylinder by bolt and nut, only in adjustable pipe
9 side of plate uses the utility model tooling.
The present embodiment structure include stuffing-box (stuffing-box structure is shown in Fig. 3), filler pressing (filler pressing structure is shown in Fig. 5) and
First sealing ring 4, the second sealing ring 8.
Stuffing-box structure is as shown in figure 3, by 5 groups of the first stuffing-box flange 3, stuffing-box shell ring, the second stuffing-box flange welderings
It forms.It is provided with groove 16 on first stuffing-box flange 3, first sealing ring 4, the first stuffing-box flange 3 and outer skull side flange are installed
2 are fastened with bolt, nut, are compressed the first sealing ring 4 and are formed sealing.First stuffing-box flange 3 uses the B-mode downhand welding of NB/T47022
The structural shape of flange, structural shape of the second stuffing-box flange 5 using slip-on-welding plate flange, the first stuffing-box flange 3, second
Stuffing-box flange 5 is made with steel plate, low manufacture cost.Stuffing-box shell ring thickness is designed by design pressure, stuffing-box
The length of shell ring is stretched out 1 maximum length of heat exchanger cylinder according to the floating tube sheet 9 that long-term heat exchanging device restrains in-site measurement and is determined.
Stuffing-box shell ring is rolled using steel plate.It is more preferable in view of there are out-of-roundness in roll bending, welding production for stuffing-box shell ring
Control floating tube sheet 9 and stuffing-box shell ring between gap to realize that good sealing effect, stuffing-box are right after group is welded into shape
Stuffing-box shell ring inner hole carries out turnery processing.
Filler pressing structure by filler pressing flange 6 with 7 groups of filler pressing shell ring as shown in figure 5, welded, filler pressing
Flange 6 is using the structural shape of slip-on-welding plate flange, and the thickness of filler pressing shell ring 7 is according to 9 seam allowance of floating tube sheet and stuffing-box
The gap of shell ring inner hole is determined as 16mm, and fall 7 end end face of filler pressing shell ring 15 ° of outer groove 17, utilizes the oblique of groove 17
Second sealing ring 8 is compressed the gap between floating tube sheet 9 and stuffing-box shell ring by face.The length of stuffing-box shell ring is according to long-term exchange
The floating tube sheet 9 of hot device tube bank in-site measurement stretches out 1 minimum length of heat exchanger cylinder and determines.
First stuffing-box flange 3 is designed according to the design pressure and inside nominal diameter of heat exchanger shell, to guarantee first
The mating connection of stuffing-box flange 3 and outer skull side flange 2.The design size of second stuffing-box flange 5 and filler pressing flange 6
It is consistent, to guarantee the mating connection of stuffing-box and filler pressing.For commonly using same inside nominal diameter, different designs pressure
The structure for pressure test of (refer to our usually used design pressure 1.6MPa, 2.5MPa, 4.0MPa), the second stuffing-box flange 5 and is filled out
Expect that pressing ring flange 6 can be unified to design by 2.5MPa, the filler pressure of inside nominal diameter same in this way, different designs pressure structure for pressure test
Circle may be implemented to exchange, and facilitate manufacture.
First sealing ring 4, the second sealing ring 8 are cut out using rubber plantation item according to the diameter of sealing surface, and interface is cut
It directly overlaps at 10 ° -15 ° of oblique angles or is fastened with glue sticking, or with tetrafluoro adhesive tape.By the first sealing ring 4,
The sealing of second sealing ring 8 forms an airtight cavity in heat exchanger shell pass, so that it may carry out shell side and suppress.
The sealing of heat exchanger shell pass and floating tube sheet 9 is that the pattern of 9 sealing surface of floating tube sheet is compressed using filler pressing, is led to
The length for crossing control stuffing-box shell ring and filler pressing shell ring 7 is just able to satisfy floating tube sheet 9 and stretches out the different length of heat exchanger cylinder 1
The needs of degree.Inside nominal diameter same in this way, the other heat exchanger of same pressure stage can complete pressure testing as long as a set of tooling, simultaneously will
The the second stuffing-box flange 5 and filler pressure of the structure for pressure test of the same inside nominal diameter of wirking pressure 1.6MPa, 2.5MPa, 4.0MPa
Circle flange 6 is designed to a kind of specification, keeps the filler pressing of the structure for pressure test of same inside nominal diameter, different pressures rank mutual
It changes, strengthens the versatility of structure for pressure test.On the other hand, outer skull side flange 2 is borrowed with the sealing of 3 junction of the first stuffing-box flange
With O shape rubber seal rings for seal principle, can be born most using the pattern that faying face opens groove installation O shape rubber seal appropriate
Big pressure can reach 100MPa, and sealing effect is good, after sealing surface compact, substantially without fastening repeatedly again during suppressing,
It is laborsaving time saving.Sealing element the first sealing ring 4, the second sealing ring 8 are used uniformly same diameter rubber plantation item according to sealing surface diameter
It is cut out, makes sealing element that there is interchangeability, and reusable, use cost is low.Moreover this tooling all uses spiral shell
Bolt, nut fastening, it is compact-sized, it is easy to install and use simple.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.It is not retouched in detail in this specification
That states partly belongs to the prior art well known to professional and technical personnel in the field.
