Description
Technical field
The utility model is related to tube coupling, more particularly to a kind of cup-shaped tube coupling of anticorrosion.
Background technology
Either ship for civil use or military boats and ships, are designed with a large amount of hull valves or kingston valve are used when working in the seawater
With control seawater enter row.And the cup-shaped tube coupling of hull valve（Hereinafter referred to as cup-shaped tube coupling）As the supporting construction of hull valve, with side of a ship body
(referring to Fig. 1) is welding as one, in design-build, cup-shaped tube coupling mainly considers its machinery and welding performance in terms of selection, leads to
Manufactured frequently with the steel close with Ship Structure material property.The flange of the hull valve being connected with cup-shaped tube coupling is usually xenogenesis
Metal.Cup-shaped tube coupling faces the environmental factor such as seawater scouring in external dynamic sea immersion and pipeline in actual applications, with pipeline method
The sealing surface groove inner side local corrosion of orchid connection is more serious, and more serious general corrosion would generally occur on bore area.
Even if once the position occurs corrosion failure being closed in hull valve, seawater still is able to be entered in cabin by site of perforation,
The normal operation of other equipment, jeopardizes the safety of naval vessel and ship in influence ship, very harmful.
The content of the invention
In order to solve the above problems well, the purpose of this utility model there is provided a kind of cup-shaped tube coupling of anticorrosion, lead to
Cross to cup-shaped tube coupling endoporus titanium pipe-inserted, flange face using electron beam welding technology inlay titanacycle isolation pipeline maritime interior waters with it is cup-shaped
Tube coupling body contacts, while insulation processing is carried out with coating at electron beam weld, so as to solve dissimilar metal in seawater
In galvanic corrosion problem, solve briny environment under, to the general corrosion and localized corrosion problems of cup-shaped tube coupling body.
The purpose of the present invention is achieved through the following technical solutions：
A kind of cup-shaped tube coupling of anticorrosion, cup-shaped tube coupling outside is designed with pump pressure experiment bolt and is detected for being pumped；Cup-shaped pipe
Section is attached with pipeline flange by the combination of bolt, nut and pad, and is sealed using seal washer, while cup-shaped
When tube coupling and pipeline flange are connected, the bolt, nut and pad and pipeline flange are avoided by insulation spacer and insulating sleeve
Directly contact；And in the cup-shaped tube coupling endoporus titanium pipe-inserted, titanacycle is inlayed in flange face, completely cut off pipeline maritime interior waters and cup
The contact of shape tube coupling.
Further, the bolt, nut and pad are steel part.
Further, the pipeline flange is titanium alloy side of a ship outer valves flange.
Further, the titanium tube and titanacycle are attached by the method for electron beam welding, and in electron beam welding weldering
At seam insulation processing is done using coating.
Further, with pressure hull by being welded to connect, cup-shaped tube coupling side of a ship outside is directly exposed to seawater to cup-shaped tube coupling
Environment or with the pre-buried welding of outboard steel.
The utility model having the beneficial effect that compared to existing technology：
1st, the cup-shaped tube coupling of anticorrosion described in the utility model, by cup-shaped tube coupling endoporus titanium pipe-inserted, flange face edge
Embedding titanacycle, completely cuts off pipeline maritime interior waters and cup-shaped tube coupling body contacts, while by insulating coating at electron beam weld
Reason, so as to solve the problems, such as galvanic corrosion；
Right when the 2nd, the cup-shaped tube coupling of anticorrosion described in the utility model, cup-shaped tube coupling and titanium alloy pipeline or valve body connection
Junction increases gasket seal, plays a part of sealing, and now contact surface is that same metal contact does not exist potential corrosion.In bolt
Steel Bolt is avoided by way of insulating sleeve and insulation spacer are installed with titanium alloy pipeline or valve body mounting hole and titanium is closed
The directly contact of golden pipeline or valve body, serves corrosion-resistant effect.
