Abstract
The utility model discloses a novel copper steel friction welding connection warship broadside cup-shaped tube joint. A tube joint body is comprised. The tube joint body comprises a steel outer ring which can be welded with a warship broadside steel plate and a copper inner ring. The steel outer ring is sheathed on the outer round surface of the copper inner ring. One end of the copper inner ring is a flange end which is connected with a warship broadside inner copper alloy sea valve. The other end of the copper inner ring is an outer side end which extends out of the warship broadside. The end face of the outer side end of the copper inner ring is flush with one end face of the steel outer ring. The copper and steel composite cup-shaped tube joint is used, and the part which contacts the seawater is made of copper alloy which is the same as the material of the sea valve, thus potential difference corrosion of a flange is eliminated. Compared with a cast steel tube joint, the performances of inner wall corrosion prevention and sea creature prevention of the tube joint are greatly improved. The overall service life is no less than 10 years, and the warship repair cost is greatly saved.
Description
Technical field
?the utility model relates to tube coupling, and the cup-shaped tube coupling of new type of ship topside that particularly a kind of copper steel friction welding connects, 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 the cup-shaped tube coupling of new type of ship topside that a kind of copper steel friction welding connects, 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: the cup-shaped tube coupling of new type of ship topside that a kind of copper steel friction welding connects, there is a tube coupling body, wherein, described tube coupling body have one can with the steel outer shroud of naval vessel topside Plate Welding, a copper interior ring, steel exterior ring cap is on the periphery of copper interior ring, the flange end that in Shi Yu naval vessel, one end topside of copper interior ring, Cuprum alloy kingston valve connects, the other end of copper interior ring is the outboard end stretching out outside naval vessel topside, an end face setting of the end face of the outboard end of copper interior ring and steel outer shroud.
Further, the inner headed face of described steel outer shroud and the periphery of copper interior ring are tolerance interference fit to scheme, by hot jacket, are fixed together.
Further, the inner headed face of described steel outer shroud and the periphery of copper interior ring link together by radial friction welding scheme.
The utility model forms a kind of novel cup-shaped tube coupling by alloy tube coupling and steel bushing by radial friction welding inventive combination.Owing to having adopted radial friction Welding, Cuprum alloy tube coupling and steel sleeve are closely welded as a whole, thereby have realized steel-steel welding reliably on steel hull.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, and the 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.
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 the deck of 2-2.
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 copper cup-shaped tube coupling of 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, the cup-shaped tube coupling of new type of ship topside that a kind of copper steel friction welding connects, there is a tube coupling body 1, wherein, described tube coupling body have one can with the steel outer shroud 1-1 of naval vessel topside Plate Welding, a copper interior ring 1-2, steel exterior ring cap is on the periphery of copper interior ring, the flange end 1-2-1 that in Shi Yu naval vessel, one end topside of copper interior ring, Cuprum alloy kingston valve connects, the other end of copper interior ring is the outboard end 1-2-2 stretching out outside naval vessel topside, an end face setting of the end face of the outboard end of copper interior ring and steel outer shroud.
For steel outer shroud and copper interior ring are firmly linked together, below two kinds of preferred versions:
The first, the inner headed face of described steel outer shroud and the periphery of copper interior ring are tolerance interference fit, by hot jacket, are fixed together.
It two is that the inner headed face of described steel outer shroud and the periphery of copper interior ring link together by radial friction welding.
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.
