Description
Technical field
The present invention relates to tubesheet calculation field, particularly relate to a kind of two-layer compound tube sheet.
Background technology
Tube sheet is a kind of accessory being inlaid with pipe on steel plate, first punches on tube sheet, then installs pipe in hole, and carries out being welded and fixed formation tube sheet.
During use, tube sheet typically contacts with industrial colling or other chemical mediators, impurity, salt, gas and microorganism etc. in industrial colling all can constitute the corrosion to tube sheet and weld seam, reduce the service life of tube sheet, and owing to pipe is welded on tube sheet, dismantling relatively difficult, add the difficulty of replacing, maintenance cost remains high.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of two-layer compound tube sheet, erection & lift and the efficiency of dismounting, reduces maintenance cost.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of two-layer compound tube sheet, including: top layer panel and bottom fixed plate, described top layer panel parallel is arranged on the upper surface of bottom fixed plate, it is connected with several hollow pipe between described top layer panel and bottom fixed plate, several top step hole it is provided with on described top layer panel, several bottom shoulder hole corresponding with top step hole it is respectively arranged with in described bottom fixed plate, the top of described hollow pipe is separately positioned in top step hole, the bottom of described hollow pipe is separately positioned in the bottom shoulder hole of correspondence, bolt is used to fix between described top layer panel and bottom fixed plate.
In a preferred embodiment of the present invention, described top step hole includes that bottom is installed straight hole and installs, with bottom, the top chamfer perforate that straight hole is connected.
In a preferred embodiment of the present invention, the internal diameter that straight hole is installed in described bottom is identical with the outside diameter of hollow pipe.
In a preferred embodiment of the present invention, the bottom opening diameter of described top chamfer perforate is identical with the diameter of bore of hollow pipe.
In a preferred embodiment of the present invention, described top layer panel being provided with the fixing hole of described bolt, the opening part of described fixing hole is provided with rubber seal plug.
The invention has the beneficial effects as follows: a kind of two-layer compound tube sheet that the present invention points out, utilize top layer panel and the cooperation of bottom fixed plate, hollow pipe is fixed between the two flexibly, it is not necessary to welding, assembly and disassembly are the most more convenient, reduce the cost of later maintenance.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the present invention a kind of two-layer compound tube sheet one preferred embodiment.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of two-layer compound tube sheet, including: top layer panel 1 and bottom fixed plate 2, described top layer panel 1 is set in parallel in the upper surface of bottom fixed plate 2, several hollow pipe 3 it is connected with between described top layer panel 1 and bottom fixed plate 2, several top step hole 11 it is provided with on described top layer panel 1, several bottom shoulder hole 21 corresponding with top step hole 11 it is respectively arranged with in described bottom fixed plate 2, the top of described hollow pipe 3 is separately positioned in top step hole 11, the bottom of described hollow pipe 3 is separately positioned in the bottom shoulder hole 21 of correspondence, bolt 5 is used to fix between described top layer panel 1 and bottom fixed plate 2.Under the pincer attack of top layer panel 1 and bottom fixed plate 2, hollow pipe 3 is firmly fixed in inside, the convenience that installation and removal are all compared, and need not weld, and service life is long.
Described two-layer compound tube sheet has been specifically designed top step hole 11 and bottom shoulder hole 21, described top step hole 11 includes that bottom is installed straight hole and installs, with bottom, the top chamfer perforate that straight hole is connected, bottom shoulder hole 21 is similar with the moulding in top step hole 11, is also configured with straight hole and chamfered bore.
Further, the internal diameter that straight hole is installed in described bottom is identical with the outside diameter of hollow pipe 3, and the top of hollow pipe 3 is installed straight hole by bottom and wrapped.
Further, the bottom opening diameter of described top chamfer perforate is identical with the diameter of bore of hollow pipe 3.Outside fluid flows directly into hollow pipe 3 through top chamfer perforate, and top chamfer perforate has confluxes and the effect of fast guiding.
Further, described top layer panel 1 being provided with the fixing hole 12 of described bolt 5, the opening part of described fixing hole 12 is provided with rubber seal plug 4.Rubber seal plug 4 effectively prevents the fluid of outside from bolt 5 is produced impact, extends bolt 5 service life and motility.
In sum, a kind of two-layer compound tube sheet that the present invention points out, compared with common tube sheet, eliminate welding procedure, service life is longer, and dismantles the most more convenient, advantageously reduces replacing and the maintenance cost in later stage.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
