In order to achieve the above purpose, the utility model adopts the following technical scheme:

an anticorrosion heat-insulation elbow comprises an elbow body, wherein the elbow body is formed by rolling a plate; the plate comprises at least two base plates, and adjacent base plates are connected with each other through a stamping occlusion part; the punching press interlock portion sets up the hook plate on adjacent foundatin plate including the cooperation, the hook plate is buckled for the foundatin plate border and forms, and the hook plate on the adjacent foundatin plate hooks from top to bottom, then the hook plate after the punching press colludes makes the laminating of adjacent hook plate inseparable, accomplishes the fixed connection between the adjacent foundatin plate.

Further, the number of the base plates is four.

Furthermore, a plurality of groups of rivet holes are correspondingly arranged on the plate, the rivet holes are close to the rolling seams of the plate, and pull rivets are arranged in the rivet holes.

Furthermore, the number of the rivet holes is eight, and two groups are respectively arranged on each foundation plate.

Furthermore, the base plate is made of iron.

The utility model discloses following beneficial technological effect has:

the utility model discloses in interconnect through punching press interlock portion between the adjacent foundatin plate for the panel itself of having assembled does not have through-hole and slit, has strengthened the leakproofness of the elbow body itself after rolling up well greatly, effectively avoids external steam, impurity etc. to get into in the anticorrosive heat preservation elbow and then ageing inefficacy such as heat preservation, anticorrosive coating with higher speed, is favorable to working medium pipeline's permanent protection, this application modern design, the installation is under construction very convenient, has very strong practicality.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-3, the corrosion-resistant and heat-insulating elbow according to the embodiment includes an elbow body 1, and the elbow body 1 is formed by rolling a plate; the plate comprises four base plates 2, the base plates 2 are made of iron, and the adjacent base plates 2 are connected with each other through a stamping occlusion part 3; punching press interlock portion 3 sets up hook plate 4 on adjacent foundatin plate 2 including the cooperation, and hook plate 4 is buckled for foundatin plate 2 border and forms, and hook plate 4 on adjacent foundatin plate 2 hooks from top to bottom, then hook plate 4 after the punching press colludes makes adjacent hook plate 4 laminating inseparable, accomplishes the fixed connection between the adjacent foundatin plate 2.

Correspond on the panel and be provided with eight rivet holes, be provided with two sets of respectively on each foundatin plate 2, be provided with in the rivet hole and draw rivet 5, the rivet hole is close to the book system seam 6 department of panel, and the book system seam 6 of preferred panel is located elbow plate body 1's leading flank or trailing flank, thereby avoids outside steam, impurity etc. to influence the life-span of 1 inboard heat preservation of elbow body, anticorrosive coating in getting into elbow body 1 through the book system seam 6 of panel.
