Processing a specific purpose tool for heat exchanger expand tube place seepage, belonging to heat exchange equipment maintenance technique field, for solving the technical problem of heat exchanger expand tube place seepage in prior art.Technical scheme is: it is made up of the joint that rises, multidiameter, sliding sleeve and door, the shank of joint of rising is installed in multidiameter Left-side center hole, sliding sleeve is set in multidiameter interlude, sliding sleeve and multidiameter interlude are matched in clearance, sliding sleeve external diameter is less than multidiameter left end shaft shoulder diameter, and multidiameter right axis section installs door.During use, aimed at by expanded joint head in heat exchanger tube, the shaft shoulder on the left of hand grip sliding sleeve reciprocating percus-sion intermediate, such expanded joint head makes the metallic walls of tube end be squeezed and the generation flowing plastic deformation that swollen, thus heat exchange tube-to-tube sheet connection is closely connected; Expanded joint is complete, holds sliding sleeve and clashes into door in the other direction, can take out expanded joint head.The utility model is simple and reliable for structure, expanded joint Be very effective, and operation use safety, durable, popularizing application prospect is wide.
Description
Technical field
The utility model relates to a kind of specific purpose tool processing heat exchanger expand tube place seepage, belongs to heat exchange equipment maintenance technique field.
Background technology
Heat exchanger is extensive use in the industrial production, is mainly used to the transmission realizing heat, makes heat pass to cryogen by high temperature fluid.One of subject matter that heat exchanger exists is exactly leak, and leaks and has interior leakage and leak outside two kinds: leaking outside is in operation easily is found, and also easily processes; For internal leakage, generally mainly refer to that heat exchanger tube leaks, common are two kinds of situations a kind of is that rising of exchanger tubes and tubesheets connects place's seepage, and another kind is that heat exchanger tube itself leaks.Leak for heat exchanger tube itself, heat exchanger tube blocks by replacing heat exchanger tube or processing plug; For exchanger tubes and tubesheets expanded joint place seepage, general reason is often because pressure oscillation and variations in temperature make exchanger tubes and tubesheets place have gap, produce seepage, there is the often bad solution of this situation, due to long-time use, the plastic deformation ability of heat exchanger tube is poor, needs stronger External Force Acting to produce plastic deformation; In addition for the online heat exchanger installed, by the restriction in in-site installation environment, space etc., process bothers more.
Utility model content
Technical problem to be solved in the utility model is to provide the specific purpose tool of a kind of structure simple, easy and simple to handle, efficient process heat exchanger expand tube place seepage, solves the defect in background technology.
The technical scheme solved the problems of the technologies described above is:
A kind of specific purpose tool processing heat exchanger expand tube place seepage, it is made up of the joint that rises, multidiameter, sliding sleeve and door, the shank of joint of rising is installed in multidiameter Left-side center hole, sliding sleeve is set in multidiameter interlude, sliding sleeve and multidiameter interlude are matched in clearance, sliding sleeve external diameter is less than multidiameter left end shaft shoulder diameter, and multidiameter right axis section installs door.
The specific purpose tool of above-mentioned process heat exchanger expand tube place seepage, also comprise pull-out bar in formation, pull-out bar is external thread structure, and multidiameter right axis section has center screw, is threaded with pull-out bar.
The specific purpose tool of above-mentioned process heat exchanger expand tube place seepage, described in the rise head of joint be taper, shank is externally threaded cylindrical for having.
The specific purpose tool of above-mentioned process heat exchanger expand tube place seepage, described multidiameter Left-side center hole has internal thread, is connected with the shank threads of the joint that rises; Described multidiameter right axis section has external screw thread, and door center has screw and is threaded with multidiameter right axis section.
The specific purpose tool of above-mentioned process heat exchanger expand tube place seepage, described sliding sleeve is cylindrical shape, and the gap of sliding sleeve and multidiameter interlude is 0.10 ~ 0.15mm, and described multidiameter overall length is 250mm ~ 400mm.
The specific purpose tool of above-mentioned process heat exchanger expand tube place seepage, described sliding sleeve is cylindrical shape, and described sliding sleeve outer surface is knurling structure.
The beneficial effects of the utility model:
When using the utility model, expanded joint head is aimed in heat exchanger tube, the shaft shoulder on the left of hand grip sliding sleeve reciprocating percus-sion intermediate, such expanded joint head makes the metallic walls of tube end be squeezed and the generation flowing plastic deformation that swollen, thus heat exchange tube-to-tube sheet connection is closely connected; Expanded joint is complete, holds sliding sleeve and clashes into door in the other direction, can take out expanded joint head.The utility model is simple and reliable for structure, expanded joint Be very effective, and operation use safety, durable, popularizing application prospect is wide.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Be labeled as in figure: the joint 1 that rises, multidiameter 2, sliding sleeve 3, door 4, pull-out bar 5.
Detailed description of the invention
As shown in the figure, the utility model is made up of the joint 1 that rises, multidiameter 2, sliding sleeve 3, door 4 and pull-out bar 5, the female centre bore of tool is had on the left of multidiameter 2, right axis section has external screw thread and right axis section center has screw, joint 1 head that rises is taper, shank is externally threaded cylindrical for having, rise by the shank of joint 1 with multidiameter 2 Left-side center hole for being threaded, cylindrical shape sliding sleeve 3 is set in the interlude of multidiameter 2, and gap is 0.10 ~ 0.15mm between the interlude of multidiameter 2, guarantee that sliding sleeve 3 can be free to slide at the interlude of multidiameter 2; Door 4 center screw is threaded with multidiameter 2 right axis section; Pull-out bar 5 is external thread structure, is threaded with the center screw of multidiameter 2 right axis section.
The overall length of the utility model multidiameter 2 is 250mm ~ 400mm, and the joint 1 that rises is the assembly that multiple head sizes is different, shank is measure-alike, the joint 1 that rises head sizes can being selected to match with it according to the heat exchanger tube diameter leaked; Sliding sleeve 3 outer surface does annular knurl process.
Using method of the present utility model is as follows:
First, according to the expanded joint head 1 that the specification of leaking heat exchanger tube selects head sizes and heat exchanger tube diameter to match, joint 1 shank that rises is screwed in the Left-side center screw of multidiameter 2; Then, sliding sleeve 3 is inserted in the interlude of multidiameter 2, expanded joint head 1 is aimed in heat exchanger tube, the promptly shaft shoulder on the left of sliding sleeve 3 reciprocating percus-sion multidiameter 2, such expanded joint head 1 makes the metallic walls of tube end be squeezed and be swollen, make heat exchanger tube produce flowing plastic deformation, thus heat exchange tube-to-tube sheet connection is closely connected; If desired increase expanded joint strength, hand hammer can be adopted to knock the right axis section end of multidiameter 2, increase amount of plastic deformation; Exchanger tubes and tubesheets expanded joint is complete, need dismounting rise joint 1 time, door 4 is screwed in the right axis section of multidiameter 2, holds sliding sleeve 3 and in the other direction clash into door 4, coordinate pull-out bar 5 to stretch out and can conveniently take out simultaneously.
The utility model structure is simple, and easy for operation, two people's compounding practices, repeatedly use through scene, respond well, can meet scene rush to repair construction needs.
