Abstract
The utility model discloses a marine anti-corrosion tube plate connecting joint, which is characterized by comprising an embedded plate (2) embedded in a plate (1), a tube (3) is penetratingly arranged on the embedded plate (2), flanges (5) are fixed on two sides of the embedded plate (2) via connecting bolts (4), gaskets (6) are disposed among the flanges (5) and the embedded plate (2), and the thickness of the embedded plate (2) is larger than that of the plate (1). The marine anti-corrosion tube plate connecting joint is simple in structure and skillful in design, and can prevent electrochemical corrosion from being generated due to the fact that special materials are selected between a tube and a plate.
Description
Technical field
The utility model relates to a kind of tube sheet jointing, and especially a kind of being applied on the boats and ships can effectively prevent because of adopting foreign material to produce the tube sheet jointing of electrochemical corrosion effect between pipe fitting and the plate.
Background technique
Aluminum alloy is because of its good physics, chemical property, application in shipbuilding, carrier is increasingly extensive, especially aspect hull structure loss of weight, raising headway, seawater corrosion resistance ability and the minimizing energy consumption more and more important effect being arranged, adopt aluminum alloy to become a trend as the shipbuilding stock.And in the structure of boats and ships, often exist some to run through the seawaterline pipe fitting that is used to carry seawater of plate, these pipe fittings need adopt non-aluminum alloy material to make (generally selecting Stainless Steel Tube for use), because aluminum alloy in the seawater that flows the ulcer corrosion can take place, this is the corrosion that a kind of rate of corrosion is exceedingly fast.But this just makes between the plate (material is an aluminum alloy) that is in contact with one another and the pipe fitting (material is non-aluminum alloy) and has potential difference, and the contact between this dissimilar metal can cause the electrochemical corrosion effect in seawater, seriously influenced the working life of boats and ships.Therefore need a kind of linkage structure that can address the above problem or mode now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, can prevent because of selecting foreign material for use between pipe fitting and the plate, and produce the tube sheet jointing of electrochemical corrosion effect.
Concrete solution of the present utility model is: a kind of boats and ships corrosion protection tube sheet jointing, it is characterized in that: it comprises the insert plate 2 that is embedded in the plate 1, on insert plate 2, be penetrated with pipe fitting 3, both sides at insert plate 2 are fixed with flange 5 by connecting bolt 4, are provided with pad 6 between flange 5 and the insert plate 2.
The thickness of described insert plate 2 is greater than the thickness of plate 1.
The utility model is compared with prior art, has following advantage:
The tube sheet jointing of this kind of structural type, it is simple in structure, design ingeniously, rationally distributed, its special construction can prevent that the parts point of contact of different metal materials is exposed outside, come in contact with seawater, and producing the electrochemical corrosion effect, the tube sheet jointing of this structural type can also guarantee the intensity and the close property of plate, simultaneously its part thickening that may corrode, increase corrosion allowance, prolonged the working life of boats and ships; Therefore we can say that this tube sheet jointing has possessed multiple advantage, be particularly suitable in industries such as shipbuilding, transportation, applying that its market prospects are very wide.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of boats and ships corrosion protection tube sheet jointing, it comprise one can fixedly embedded insert plate 2 on plate 1, on insert plate 2, fixedly be penetrated with pipe fitting 3, both sides at insert plate 2 are fixed with flange 5 by connecting bolt 4, be provided with pad 6 between flange 5 and the insert plate 2, and the thickness of insert plate 2 is greater than the thickness of plate 1.
When the jointing of this kind structural type is applied on the hull of aluminum alloy material, insert plate 2 aluminium alloy materials are made, select for use stainless steel material to make with the pipe fitting 3 that insert plate 2 directly contacts, flange 5 in insert plate 2 outsides is stainless steel material with connecting bolt 4 and makes, and also be provided with pad 6 between flange 5 and insert plate 2, pad 6 selects for use insulation rubber to support.Can directly not contact between the flange 5 of different materials and the insert plate 2 like this, prevent from or slow down it electrochemical corrosion takes place.
And, strengthen the size of insert plate 2 because the thickness of insert plate 2 is greater than the thickness of plate 1, and can avoid plate 1 part to bear higher stress, guaranteed the intensity and the close property of plate 1, also increased corrosion allowance simultaneously.
Claims (2)
1. boats and ships are with corrosion protection tube sheet jointing, it is characterized in that: it comprises the insert plate (2) that is embedded in the plate (1), on insert plate (2), be penetrated with pipe fitting (3), both sides at insert plate (2) are fixed with flange (5) by connecting bolt (4), are provided with pad (6) between flange (5) and the insert plate (2).
2. boats and ships according to claim 1 corrosion protection tube sheet jointing, it is characterized in that: the thickness of described insert plate (2) is greater than the thickness of plate (1).
