Description
Technical field
The present invention relates to a kind of elbow more particularly to a kind of Double-metal composite elbows.
Background technique
With the extensive use of stainless steel composite pipe, matched Double-metal composite elbow uses more and more, mesh
Preceding common Double-metal composite elbow generally uses three kinds of techniques：First is that dried shrimp elbow, as patent 201220095121.5 proposes
A kind of corrosion-resistant alloy lined composite mitre elbow is made using compound pipeline complex pipeline by setting-out, cutting, butt welding process, easy to leak,
Bearing capacity is low, service life is short；Second is that interior dried shrimp elbow, the kind integral lining corrosion resistant proposed such as patent 201420490748.X
Alloy composite elbow is lost, outside is carbon steel seamless elbow, and inside is curved using the stainless steel welded dried shrimp that is welded into, and rises into using liquid
Type, the technique welding difficulty is big, erosion resistant coating easy to leak, layering；Or third is that punched bend, what patent 201120425968.0 proposed
Punching type Bending Pipes, the technique are stamped and formed out using metallurgical composite plate, corrosion resistance and good, but cost of manufacture is high,
The pure stainless steel material of close prices, can not be acceptable to the market.
Summary of the invention
Solving the scheme that above-mentioned technical problem uses is：A kind of Double-metal composite elbow, to solve Double-metal composite elbow
Safety is bad, the problem of service life is short, not withstand pressure, anti-corrosion layer is easily layered, high production cost.Bimetallic of the invention is compound
Elbow has that corrosion resistance stabilization, long service life, at low cost, the strong bore range of bearing capacity is wide, and has metallurgical compound
The characteristics of, bond strength is high, has a wide range of application.
In order to achieve the above objectives, the technical scheme adopted by the invention is that：A kind of Double-metal composite elbow includes that carbon steel is curved
Head and the inner surface stainless steel layer for being covered on the Carbon Steel Elbow, the stainless steel layer are spliced by symmetrical two pieces of stainless steel faceplates
It forms, two pieces of stainless steel faceplates form stainless steel layer in Carbon Steel Elbow interior welds, and two pieces of stainless steel faceplates connect
The welding pool on touching side infiltrates through the Carbon Steel Elbow.
Further, two end of stainless steel layer respectively sets one and ring is welded and fixed, and the ring that is welded and fixed is a circle
Ring is welded and fixed the Stainless Steel layer side that ring and two stainless steel faceplates are spliced into and is welded to connect described in one, the weldering
Connect fixed ring outer surface and the Carbon Steel Elbow inner surface have a spacing, it is described be welded and fixed ring outer surface and the Carbon Steel Elbow it
Between spacing pass through welded connecting.
The beneficial effects of the present invention are：
1, the outside of Double-metal composite elbow is Carbon Steel Elbow, has preferable bearing capacity, internal stainless steel layer and carbon
Steel elbow interior wall fits closely, and weld seam is arranged along flow direction, flow-passing surface is smooth, and resistance is small, and abrasion is small, and service life is long.
2, weld seam is merged stainless steel layer with Carbon Steel Elbow welding, so that the combination of two kinds of materials of carbon steel and stainless steel is strong
Degree is much larger than the curved formula of interior dried shrimp, so that pipeline has the larger temperature difference of receiving and negative pressure ability, applicable performance get a promotion.
3, nozzle soldering and sealing is handled, and is conducive to construction welding, is improved the installation quality of product.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples：
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is A-A sectional schematic diagram.
Attached drawing 3 is the preferred schematic diagram of the utility model.
Attached drawing 4 is stainless steel faceplate preferred structure schematic diagram.
Attached drawing 5 is P point enlarged diagram in Fig. 3.
In figure：Stainless steel layer 3, stainless steel faceplate 4, ring 5 is welded and fixed in Carbon Steel Elbow 2.
Specific embodiment
In conjunction with attached drawing of the invention, the technical solution of the embodiment of the present invention is explained and illustrated, but following embodiments
It is merely a preferred embodiment of the present invention, and not all, based on the fact that applying the embodiment in mode, those skilled in the art of the present technique exist
Other embodiments obtained under the premise of creative work are not made, protection scope of the present invention is belonged to.
As shown in Figure 1 to Figure 2, a kind of Double-metal composite elbow includes Carbon Steel Elbow 2 and is covered on the Carbon Steel Elbow 2
Inner surface stainless steel layer 3（Preferably, stainless steel layer 3 is with a thickness of 0.8~4mm）, stainless steel layer is by symmetrical two pieces of surface stainless steels
Plate 4 is spliced, and two pieces of stainless steel faceplates 4 form stainless steel layer 3 in 2 interior welds of Carbon Steel Elbow, and two pieces described stainless
The be in contact welding pool on side of steel facing 4 infiltrates through the Carbon Steel Elbow 2, and welding pool infiltrates through the outer wall for making stainless steel layer 3
It is fitted closely with the inner wall of Carbon Steel Elbow 2,3 two end of stainless steel layer connect it with 2 inner wall of Carbon Steel Elbow by welding, thus shape
At longitudinal two connecting sewings（Respectively there is a weld seam on 4 two side of stainless steel faceplate, and the welding pool of weld seam infiltrates through the carbon steel
Elbow 2）And two end circumferential connecting sewing（A circumferential weld seam is respectively provided at 4 two end of stainless steel faceplate）.
In Fig. 3,5,3 two end of stainless steel layer respectively sets one and ring 5 is welded and fixed, and it is a circular rings that ring 5, which is welded and fixed,（Weldering
Connect fixed ring 5 with a thickness of 2/3rds of 3 thickness of stainless steel layer, generally higher than 1mm）, ring 5 and two are welded and fixed described in one
3 side of Stainless Steel layer that a stainless steel faceplate 4 is spliced into is welded to connect, and 5 outer surface of ring is welded and fixed and the carbon steel is curved
First 2 inner surface has spacing, and the spacing between 5 outer surface of ring and Carbon Steel Elbow 2 is welded and fixed by being welded to connect, ring is welded and fixed
Pad between 5 and Carbon Steel Elbow 2 is soldered fixed ring 5 makes it not be in contact with the liquid in bend pipe to covering, to make
3 two end of stainless steel layer and the connection of Carbon Steel Elbow 2 are tighter.
Such as Fig. 4, stainless steel faceplate 4 is that " watt " shape stainless steel is spliced, and tiles stainless steel can pass through punching press or casting
Be equal to Carbon Steel Elbow internal diameter at, outer diameter, the two be bonded by cold heat assembly technology after by will be stainless to weld seam
Steel layer merges to form two longitudinal seams with Carbon Steel Elbow inner wall, achievees the effect that metallurgical bonding.
Installation process, it is first that a molding Carbon Steel Elbow 2 is fixed, then that two pieces of stainless steel faceplates 4 are placed on carbon steel is curved
In first 2, two pieces of stainless steel faceplates 4 are made to form a complete stainless steel layer 3 in Carbon Steel Elbow 2 by welding later, two pieces
Weld seam welding pool on stainless steel faceplate 4 infiltrates through the Carbon Steel Elbow 2, and 3 two end of stainless steel layer is welded on carbon steel later
It, can also be using the inner wall that the connection of ring 5 two end of stainless steel layer and 2 two end of Carbon Steel Elbow is welded and fixed on the inner wall of elbow 2.
Structure in this example is only that the illustration and explanation for claim are not answered in order to mass reading understanding
It is considered as the limitation for claim, the range and legal equivalent feature that protection scope of the present invention should be recorded with claim are
It is quasi-.
