Description
Technical field
This utility model is related to equipment heat exchanger tube leakage proof field, more particularly to a kind of novel heat exchange pipe plug.
Background technology
Frequently with welding closure, plug mostly adopts round steel, with lathe process into circular cone for domestic heat exchanger tube closure at present
Type, the external diameter value of plug microcephaly is less than the inner diameter values of heat exchanger, and large head external diameter value, will be stifled when using more than the inner diameter values of heat exchanger
Head is placed in heat exchanger tube pounds tight rear welding；But there are many drawbacks in welding closure, such as one side welding stress is easily caused
Surrounding tube leaking, if on the other hand having inflammable and explosive medium in heat exchanger, cannot carry out heat exchanger tube using traditional plug
Closure.
Utility model content
The purpose of this utility model is to provide a kind of novel heat exchange pipe plug, it is therefore intended that solved existing using welding
The drawbacks of existing during technology closure heat exchanger tube.
To achieve these goals, this utility model is employed the following technical solutions：
A kind of novel heat exchange pipe plug, including package assembly, internal member and bolt, package assembly and internal member are frustum type；
The external diameter of package assembly stub end is more than the internal diameter of heat exchanger tube, and the external diameter of the little head end of package assembly is less than the internal diameter of heat exchanger tube, package assembly
Center offers through hole, and through hole is made up of screwed hole and fastener hole two parts, the diameter with diameter greater than screwed hole of fastener hole, spiral shell
Pit is opened in the little head end of frustum type package assembly, and the diameter of screwed hole matches with the external diameter of bolt；Internal member stub end
External diameter is less than the internal diameter of heat exchanger tube and more than the internal diameter of fastener hole, and the external diameter of the little head end of internal member is bored less than the internal diameter of fastener hole
The little head end of bench-type internal member offers blind hole, and the diameter of blind hole matches with the external diameter of bolt；The length value of bolt is equal to logical
The length value in hole.
The beneficial effects of the utility model：
Novel heat exchange pipe plug described in the utility model, employs package assembly, internal member and bolt, and former using expansion
Reason gets up triplicity, when heat exchanger tube is blocked, without welding, need to only tighten on bolt, and closure is easier, using model
Enclose also more extensive；Simultaneously novel heat exchange pipe plug described in the utility model can also be disassembled from heat exchanger tube, just with
Maintenance.
Description of the drawings
Fig. 1 is the structural representation of package assembly described in the utility model；
Fig. 2 is the structural representation of internal member described in the utility model；
Fig. 3 is use state figure of the present utility model.
Specific embodiment
As depicted in figs. 1 and 2：Novel heat exchange pipe plug described in the utility model, including package assembly 1, internal member 2 and spiral shell
Bolt 6, wherein, package assembly 1 and internal member 2 are frustum type, and frustum type not only easily makes, while the diameter transition of frustum type is put down
It is slow, be conducive to making internal member 2 smoothly enter package assembly 1, while being also beneficial to package assembly 1 further gos deep into heat exchanger tube 7.
, more than the internal diameter of heat exchanger tube 7, the external diameter of the little head end of package assembly 1 is less than heat exchanger tube 7 for the external diameter of the stub end of package assembly 1
Internal diameter, it is ensured that the little head end of package assembly 1 can enter heat exchanger tube 7, stub end can not enter heat exchanger tube 7, and the center of package assembly 1 is also opened
Through hole is provided with, through hole is connected with the two parts of fastener hole 4 by screwed hole 3 and constituted, the diameter with diameter greater than screwed hole 3 of fastener hole 4,
Fastener hole 4 is used to accommodate internal member 2, and screwed hole 3 is opened in the little head end of frustum type package assembly 1, the diameter and bolt of screwed hole 3
6 external diameter matches.
The external diameter of the stub end of internal member 2 is less than the internal diameter of heat exchanger tube 7 and more than the internal diameter of fastener hole 4, it is ensured that when internal member 2
During in the fastener hole 4 of package assembly 1, internal member 2 can extrude fastener hole 4, so that package assembly 1 expands；The microcephaly of internal member 2
Internal diameter of the external diameter at end less than fastener hole 4, it is ensured that internal member 2 can smoothly enter fastener hole 4, frustum type internal member 2 it is little
Head end offers blind hole 5, and diameter and the external diameter of bolt 6 of blind hole 5 match.
The length value of bolt 6 is equal to the length value of through hole, to ensure that internal member 2 is entered after fastener hole 4, when tightening bolt 6,
Internal member 2 and package assembly 1 being capable of move toward one anothers.
As shown in Figure 3：During using novel heat exchange pipe plug described in the utility model, the internal diameter of heat exchanger tube 7 is first according to
Select suitable plug；Then the internal member 2 of plug is set in the package assembly 1 of plug（Fastener hole 4）It is interior, and bolt 6 of screwing on；
Then plug is placed in the heat exchanger tube 7 for needing closure as shown in Figure 3, and tightens bolt 6；Now, because internal member 2 is fixed
In fastener hole 4, therefore during bolt 6 is tightened, internal member 2 further will be moved into fastener hole 4 and further squeezed
Compress solid hole 4, package assembly 1 will under the extruding of internal member 2 expansion so that package assembly 1 expands so that plug plays closure
The effect of leakproof.
Novel heat exchange pipe plug described in the utility model, employs package assembly 1, internal member 2 and bolt 6, and using swollen
Swollen principle gets up triplicity, when heat exchanger tube 7 is blocked, without welding, need to only tighten on bolt 6, and closure is easier,
Range of application is also more extensive；Under simultaneously novel heat exchange pipe plug described in the utility model can also be dismantled from heat exchanger tube 7
Come, just with maintenance.
Finally it should be noted that：Various embodiments above is only illustrating the technical solution of the utility model, rather than it is limited
System；Although being described in detail to this utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It still can modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent；And these are changed or are replaced, the essence for not making appropriate technical solution departs from this practicality newly
The scope of each embodiment technical scheme of type.
