Description
Technical field
The utility model is related to a kind of stuffing box type heat exchanger sealing structure, refers specifically to a kind of single tube journey floating head heat exchange
Packing box seal structure in device screw-threaded coupling.
Background technology
The packing box seal structure of prior art as shown in figure 1, mainly include tube side adapter 1, shell side adapter 2, back-up ring 3,
Soft metal ring 4, airtight and watertight padding 5, hold-down ring 6, flange 7.The packing box seal pair of this kind of structure, back-up ring 3 and the end of hold-down ring 6
15 degree of inclination angles are in inner side（Such as Fig. 2）, it is unfavorable for compressing airtight and watertight padding 5；Soft metal ring 4 is placed in angle of heel and sealing in back-up ring 3
Between filler 5, and it is not provided between the tip inside inclination angle of hold-down ring 6 and airtight and watertight padding 5；The compression of airtight and watertight padding 5 is directly by pressing
Tight ring 6 screws realization with the internal and external threads of both tube side adapters 1, in the assembly or disassembly structure, due to airtight and watertight padding and pressure
Frictional force between tight ring is very big, and large-diameter thread itself assembling is more difficult, therefore required pretightning force is very big so that assembling is tired
Difficulty, thrust deficiency causes sealing effectiveness bad.
Utility model content
The utility model provides packing box seal structure in a kind of single tube journey floating head heat exchanger screw-threaded coupling, preferably protects
Sealing effectiveness is demonstrate,proved, and assembled, repaired more convenient, applicable pressure limit is wider.
To achieve these goals, the technical solution adopted in the utility model is：
Packing box seal structure in a kind of single tube journey floating head heat exchanger screw-threaded coupling, mainly includes tube side adapter, shell side
Adapter, tube side adapter is nested in shell side adapter and forms packing cavity between the two, and back-up ring, soft gold are set gradually in described filler chamber
Category ring, airtight and watertight padding and hold-down ring, thread-locking ring；One end of tube side adapter is affixed with back-up ring, the relative other end and
Locked by screw thread between thread-locking ring, and trip bolt is assemblied in the axial threaded hole of thread-locking ring, is coordinated
Contacted with hold-down ring afterwards, hold-down ring is contacted with airtight and watertight padding.
There are inclined 15 degree of inclination angles laterally one end of the back-up ring contact airtight and watertight padding.
There are inclined 15 degree of inclination angles laterally one end of the hold-down ring contact airtight and watertight padding.
The soft metal ring is placed in airtight and watertight padding two ends, and is respectively placed in inclination outside the outer big end of angle of heel of back-up ring and hold-down ring
At the big end in angle.
The outer tube component is reducer, and its big end flanges is affixed with flange, and flange takes over affixed with shell side.
Compared with prior art, structure of the present utility model, airtight and watertight padding compression effect is good, changes rubbing surface and sealing
Filler compacting structure, making the pretightning force of thread-locking ring reduces, it is final compress airtight and watertight padding by tighten trip bolt transmission power to
Hold-down ring is realized, makes assembling and repair more convenient, and can reach preferable sealing effectiveness, and applicable pressure limit is wider.
Brief description of the drawings
Fig. 1 is the interior packing box seal structural representation of prior art.
Fig. 2 is the partial enlarged drawing in I portions in Fig. 1.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the partial enlarged drawing in II portions in Fig. 3.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 3, packing box seal structure in a kind of single tube journey floating head heat exchanger screw-threaded coupling, mainly including tube side
Adapter 1, shell side adapter 2, back-up ring 3, soft metal ring 4, airtight and watertight padding 5, hold-down ring 6, thread-locking ring 7, trip bolt 8, flange
9th, outer tube component 10.The packing box seal structure is linked in shell side adapter 2, when tube bank is flexible, in shell side adapter 2
Do axially reciprocating in surface.The tube side adapter 1 is nested in shell side adapter 2 and forms packing cavity between the two, the packing cavity
Inside set gradually back-up ring 3, soft metal ring 4, airtight and watertight padding 5 and hold-down ring 6, thread-locking ring 7；One end of the tube side adapter 1
Affixed with back-up ring 3, the relative other end is locked with thread-locking ring 7 by screw thread, and trip bolt 8 is assemblied in screw fastening
In the axial threaded hole of tight ring 7, contacted with hold-down ring 6 after cooperation, hold-down ring 6 is contacted with airtight and watertight padding 5.When trip bolt 8 is filled
Assigned in the ring wall axial threaded hole of thread-locking ring 7, and after thread-locking ring 7 is screwed in place, trip bolt 8 is tightened in order,
Thrust is transferred to airtight and watertight padding 5 by hold-down ring 6, it is final to compress airtight and watertight padding 5, it is pre- needed for trip bolt 8 due to tightening
Clamp force is far smaller than the pretightning force needed for screwing thread-locking ring 7, so assembly difficulty can be greatly reduced, while can also make sealing
The more consolidation of the extruding of filler 5, reaches better seal effect, with suitable for wider array of pressure limit.
The back-up ring 3, using being welded to connect, plays a part of baffle seal filler 5 with tube side adapter 1, and welding structure is compared with one
Body processing can material-saving.
The back-up ring 3 and the outside of hold-down ring 6 are provided with 15 degree of inclination angles（As shown in Figure 4）, it is therefore intended that crush seal filler 5
During, airtight and watertight padding 5 is extruded more consolidation, and packing cavity lateral direction is pressed against, make sealing effectiveness more preferable；In back-up ring 3
Soft metal ring 4 is placed between outer angle of heel and airtight and watertight padding 5 and between the outer angle of heel of hold-down ring 6 and airtight and watertight padding 5, it is therefore intended that
Baffle seal filler 5 is squeezed into the gap between the gap between back-up ring 3 and shell side adapter 2 or hold-down ring 6 and shell side adapter 2.
During the airtight and watertight padding 5 is compacted, slided without relative with the contact surface of hold-down ring 6, compared with prior art
Interior packing box seal structure is compared, and sliding friction surface has been transferred at contact surface of the hold-down ring 6 with thread-locking ring 7, due to
Coefficient of friction between steel and steel is small compared with the coefficient of friction between steel and filler, therefore required when thread-locking ring 7 is screwed
Pretightning force can be reduced, and need to only be screwed thread-locking ring 7 to initial and be compressed the state of airtight and watertight padding 5, so that it is difficult to reduce assembling
Degree.
The outer tube component 10 is reducer, and its big end nominal diameter is identical with the shell side adapter 2, small end nominal
Diameter is identical with the tube side adapter 1, as tube side interface, plays a part of connection equipment tube side and external process pipeline,
When changing airtight and watertight padding, certain operating space is reserved by dismantling the part, be easy to working drawing review.
Above content is to combine the further detailed description that specific optimisation technique scheme is made to the utility model, no
Can assert that specific implementation of the present utility model is only limited to these explanations.For the utility model person of ordinary skill in the field
For, without departing from the concept of the premise utility, some simple deformations can also be made and improved, should all be regarded as
Protection domain of the present utility model.
