Abstract
The invention discloses a tube plate with a built-in replacement tube. The tube plate comprises a circular foundation steel plate and multiple sections of hollow tubes, wherein the hollow tubes are respectively arranged in the circular foundation steel plate; a plurality of vertical step installing holes are formed in the circular foundation steel plate; the hollow tubes are respectively located in the step installing holes; a threaded hole is formed above each step installing hole; a threaded tube is screwed in each threaded hole; the bottom parts of the threaded tubes are respectively in contact with the top parts of the hollow tubes; an outer hexagon bolt end structure is arranged on the excircle of the top part of each threaded tube. Through the manner, according to the tube plate with the built-in replacement tube provided by the invention, the hollow tubes and the threaded tubes form a fluid channel; the assembly is quick; the replacement of the parts can be carried out; the maintenance is convenient, and the post-using cost is reduced.
Description
Technical field
The present invention relates to tubesheet calculation field, particularly relate to a kind of tube sheet of built-in replacement pipe.
Background technology
Tube sheet is a kind of accessory being inlaid with pipe on steel plate, first punches on tube sheet, then in hole, installs pipe, and carries out being welded and fixed formation tube sheet.
During use, tube sheet generally contacts with industrial colling or other chemical mediators, impurity in industrial colling, salt, gas and microorganism etc. all can form the corrosion to tube sheet and weld seam, reduce the service life of tube sheet, and being welded on tube sheet due to pipe, during replacing, the dismounting of pipe is more difficult, add the difficulty of maintenance, the maintenance cost in later stage is large.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of tube sheet of built-in replacement pipe, and hollow pipe is replaced convenient, reduces costs.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the tube sheet providing a kind of built-in replacement pipe, comprise: circular foundation steel plate and several sections of hollow pipes, described hollow pipe is separately positioned in circular foundation steel plate, several vertical ladder installing hole is provided with in described circular foundation steel plate, described hollow pipe lays respectively in ladder installing hole, the top of described ladder installing hole is respectively arranged with a screwed hole, screw respectively in described screwed hole and be provided with a screwed pipe, the bottom of described screwed pipe contacts with the top of hollow pipe respectively, the top cylindrical of described screwed pipe is provided with an outer-hexagonal bolt end structure.
In a preferred embodiment of the present invention, the outer setting of described screwed pipe has the screw thread corresponding with screwed hole.
In a preferred embodiment of the present invention, described circular foundation edges of plate is provided with several bolt mounting holes.
In a preferred embodiment of the present invention, the diameter of bore of described screwed pipe is identical with the internal diameter of hollow pipe.
The invention has the beneficial effects as follows: the tube sheet of a kind of built-in replacement pipe that the present invention points out, hollow pipe and screwed pipe constitute the passage of fluid, assemble fast, and can change, easy to maintenance, reduce later stage use cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of tube sheet one preferred embodiment of a kind of built-in replacement pipe of the present invention.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of tube sheet of built-in replacement pipe, comprise: circular foundation steel plate 1 and several sections of hollow pipes 3, described hollow pipe 3 is separately positioned in circular foundation steel plate 1, several vertical ladder installing hole 11 is provided with in described circular foundation steel plate 1, described hollow pipe 3 lays respectively in ladder installing hole 11, the top of described ladder installing hole 11 is respectively arranged with a screwed hole 12, screw respectively in described screwed hole 12 and be provided with a screwed pipe 2, the bottom of described screwed pipe 2 contacts with the top of hollow pipe 3 respectively, the cooperation of hollow pipe 3 and screwed pipe 2 constitutes the passage of fluid, assemble fast, the top cylindrical of described screwed pipe 2 is provided with an outer-hexagonal bolt end structure, outer-hexagonal bolt end structure convenient wrench screws, improve the efficiency of construction.
The feature of the tube sheet of described built-in replacement pipe is exactly the replaceability of hollow pipe 3 and screwed pipe 2, and the outer setting of described screwed pipe 2 has the screw thread corresponding with screwed hole 12.The position of hollow pipe 3 is fixed, sound construction, processing with low cost by screwed pipe 2.
Further, the edge of described circular foundation steel plate 1 is provided with several bolt mounting holes 13, and the convenient bolt that adopts of bolt mounting holes 13 is fixed on circular foundation steel plate 1 on other equipment.
Further, the diameter of bore of described screwed pipe 2 is identical with the internal diameter of hollow pipe 3, and inner wall smooth is easy to process, little to the resistance of fluid.
In sum, the tube sheet of a kind of built-in replacement pipe that the present invention points out, processing with low cost, installation effectiveness is high, and it is convenient to change, and the scope of application is more extensive.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
