Description
Technical field
?the utility model relates to tube coupling, and particularly a kind of cup-shaped tube coupling of new type of ship topside that has copper steel explosive clad plate, by using two kinds of different materials composite structures, reduces the corrosion of seawater to tube coupling, the working life of improving tube coupling.
Background technique
No matter be ship for civil use or military boats and ships, especially submarine, the main frame of its power system all needs cooled with seawater while turning round, and the ballast system on various naval vessel has also needed a large amount of work of entering to arrange seawater.Therefore various naval vessel is all designed with a large amount of hull valves or kingston valve, in order to control the row that enters of seawater.And the cup-shaped tube coupling of hull valve (hereinafter referred to as cup-shaped tube coupling) is as the supporting structure of hull valve, be welding as one (seeing Fig. 1) with hull, when design-build, cup-shaped tube coupling is mainly considered the performance of the aspects such as its machinery and welding aspect selection, the normal employing steel manufacture close with hull structure material property, and the flange of the hull valve being connected with cup-shaped tube coupling is generally Cuprum alloy (as materials such as BIO, B30).Cup-shaped tube coupling inwall leads directly to seawater, once even this position occur corrosion failure at hull valve in closed condition, seawater still can be entered in people cabin by site of perforation, affect the normal operation of interior other equipment of ship, the safety that jeopardizes naval vessel and ship, thereby very harmful.
Summary of the invention
The purpose of this utility model is, for well solving seawater, cup-shaped tube coupling etching problem is proposed to a kind of cup-shaped tube coupling of new type of ship topside that has copper steel explosive clad plate, by using two kinds of different materials composite structures, reduce the corrosion of seawater to tube coupling, the working life of improving tube coupling.
To achieve these goals, the technical solution of the utility model is: a kind of cup-shaped tube coupling of new type of ship topside that has copper steel explosive clad plate, include a copper inner tube and an outer tube, described outer tube is formed by the explosive clad plate pipe crimping welding of copper coin and steel plate, the outer rim side of described copper, the compound outer tube of steel be can with the steel plate of naval vessel topside Plate Welding, the interior ring side of outer tube is copper coin, and on inner pipe, the interior ring of described outer tube is connected with copper inner tube close contact outer tube sleeve.
Scheme is further: described outer tube is fixedly connected with inner tube with the welding of copper inner tube by lower end surface, copper interior ring side copper plate both sides.
Scheme is further: the connecting sewing of described copper steel explosive clad plate pipe crimping welding is copper-copper, steel-steel dual-layer welding connecting sewing.
The utility model outer tube is the bi-metal double-pipe rolling with steel copper explosive clad plate, and skin is steel, can realize the direct melting welding with hull, and internal layer is Cuprum alloy (B10 or B30), can realize direct melting welding with copper pipe joint.Blast compound plate rolls into after tubular, has a butt joint, can adopt same material welding wire to carry out melting welding welding.It is a kind of novel cup-shaped tube coupling that adopts explosive clad plate pipe crimping welding procedure.Because tube coupling and the position of contact with sea water have adopted the Cuprum alloy the same with kingston valve material, fundamentally stopped the potential difference corrosion at flange plate place, the anti-seawater corrosion grade of tube coupling inwall reaches consistent with kingston valve simultaneously.
Steel copper explosive clad plate at home market can directly be purchased.This novel tube coupling make full use of ripe explosive clad plate product as and hull between welding transition, reached and can be connected and can realize good corrosion-resistant object with hull is reliable, this tube coupling overall work life-span is not less than 10 years, has greatly saved the maintenance expenses on naval vessel.
Accompanying drawing explanation
Fig. 1 is the working state schematic representation of cup-shaped tube coupling on hull;
Fig. 2 is the utility model structural representation;
Fig. 3 is the outer tube schematic diagram that the explosive clad plate pipe crimping welding of copper coin and steel plate forms.
Embodiment
On China naval vessel and ship, the cup-shaped tube coupling standard of CB540-2004 < < topside > > is carried out in the design of current used cup-shaped tube coupling and production always, the material of standard code tube coupling should adopt 607A cast steel, as shown in Figure 1, the cup-shaped tube coupling 1 of this kind of material, although can be good at solving the welding between tube coupling and ship side steel plate 2, but cast steel material is very easily by seawater corrosion in seawater, and especially the inwall of the cup-shaped tube coupling of steel is comparatively serious by seawater directly etching situation.In addition, because kingston valve is Cuprum alloy, and between the cup-shaped tube coupling of steel, there is very strong potential corrosion.Therefore, be generally 3 to 5 years the working life of cup-shaped tube coupling, whole ship will lie up and sit pier and could repair, and cost is very large, and 2-1 is the face directly contacting with seawater outside Fig. 1 centre board, be fixed with the Cuprum alloy kingston valve being connected with cup-shaped tube coupling inside the side of a ship on 2-2 deck.
Because copper product can be resisted seawater corrosion, in order to improve the cup-shaped tube coupling that has proposed to use copper product the working life of cup-shaped tube coupling, yet the complete cup-shaped tube coupling of copper copper cannot weld with steel ship side, in order to solve tube coupling and ship side welding, therefore produced the compound cup-shaped tube coupling of steel copper of the present embodiment mode.
Referring to Fig. 2 and Fig. 3, a kind of cup-shaped tube coupling of new type of ship topside that has copper steel explosive clad plate, include a copper inner tube 1-1 and an outer tube 1-2, described outer tube is formed by the explosive clad plate pipe crimping welding of copper coin 1-2-1 and steel plate 1-2-2, the outer rim side of described copper, the compound outer tube of steel be can with the steel plate of naval vessel topside Plate Welding, the interior ring side of outer tube is copper coin, and on inner pipe, the interior ring of described outer tube is connected with copper inner tube close contact outer tube sleeve.
In order to realize the interior ring of outer tube, there is the good preferred scheme that is connected to be with copper inner tube: described outer tube is fixedly connected with inner tube with the welding of copper inner tube by lower end surface, copper interior ring side copper plate both sides.
In embodiment, the connecting sewing of described copper steel explosive clad plate pipe crimping welding is copper-copper, steel-steel dual-layer welding connecting sewing.
Owing to having adopted copper, the compound cup-shaped tube coupling of steel, adopted the Cuprum alloy the same with kingston valve material with the position of contact with sea water, stopped the potential difference corrosion at flange plate place, tube coupling inner wall anti-corrosive and anti-marine growth Performance Ratio cast steel tube coupling improve greatly simultaneously, the overall work life-span is not less than 10 years, has greatly saved the maintenance expenses on naval vessel.
