Embodiment
[0018] see Figure 1 to Figure 6 , The special-shaped pipe elbow insulation shell is divided into two symmetrical elbow shells 1 and 2 by the central plane 4, and the shell 3 is suitable for 90 ° special-shaped pipe elbow heat preservation shell. see Figure 5 with Image 6 The fasteners are self-tapping screws 7, and a plurality of self-tapping screws 7 fixedly connect the two symmetrical elbow shells 1 and 2 to form a complete special-shaped pipe elbow insulation shell. When in use, wrap the insulation layer 6 made of insulation material outside the high-temperature pipeline 5 , and the special-shaped pipe elbow insulation shells 1 and 2 are buckled outside the insulation layer 6 and fixedly connected with a plurality of self-tapping screws 7 .

The invention relates to a heat preserving shell for a special-shaped pipeline elbow of an engineering pipeline. The heat preserving shell for the special-shaped pipeline elbow is a heat preserving shell for a nonstandard pipeline elbow; and the radius R2 of a small circular arc of the heat preserving shell is greater than the radius r2 of a small circular arc of a standard pipeline elbow, and the radius R1 of a large circular arc and the radius R of a central circular arc of the heat preserving shell are equal to the radius r1 of a large circular arc and the radius r of a central circular arc of the standard pipeline elbow. When the heat preserving shell for the special-shaped pipeline elbow is pressed, in order to enhance the strength of the heat preserving shell for the special-shaped pipeline elbow and eliminate the wrinkles of the heat preserving shell for the special-shaped pipeline elbow, three convex ribs are arranged on the inner side of the heat preserving shell for the special-shaped pipeline elbow additionally; and the size of each convex rib is changed with the size of the heat preserving shell for the special-shaped pipeline elbow. The special-shaped pipeline elbow divides the heat preserving shell for the special-shaped pipeline elbow into two symmetrical elbow shells along a central plane. The heat preserving shell for the special-shaped pipeline elbow is easy to disassemble and assemble, can be used repeatedly, and has obvious economic benefits.
Description
technical field [0001] The invention relates to a special-shaped pipe elbow insulation shell of an engineering pipeline. Background technique [0002] At present, the engineering pipeline elbow insulation shells of the prior art are generally connected by multi-section iron sheet bites to form a shrimp bent structure, which is complicated to manufacture, has a long processing period, is not beautiful, and cannot be reused. There are also plastic shells formed by plastic molds, which have low strength, are easy to age, and have a short service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the existing engineering pipeline elbow insulation shells, and provide a special-shaped pipeline elbow insulation shell with reasonable design, easy disassembly and assembly, and reusability. [0004] The technical solution adopted by the present invention to solve the above technical...
