Description

Conveyor pipe cladding elbow pipe parts

The invention relates to the technical field of pipe fittings, in particular to an outer cladding elbow pipe part of a conveying pipeline.

Press, the existing conveying pipeline that provides the transportation of cold and hot fluids mainly includes a pipeline body, and a layer of insulation material is coated on the outside of the pipeline body, and a layer of metal sheath is coated on the outside of the insulation material. In this way, the insulation material covering the pipeline body can reduce the heat exchange between the cold and hot fluids and the environment during the pipeline transportation process, and the metal shell can protect the insulation material from being exposed to the sun and rain. damage.

On the pipeline conveyed by cold and heat pipes, if there is a turning point, an "elbow" will be formed, and the assembly method of the pipe body of the existing pipeline at the elbow part mainly includes three types, one of which is to The ends of the two straight tubular pipe bodies are chamfered at 45 degrees, so that the two pipe bodies set up vertically and horizontally can be connected and welded at an angle of 45 degrees, and the two pipe bodies set up vertically and horizontally Two straight tubular pipe bodies are connected by an elbow pipe, and then covered with insulation material, such as the "Shell of the outer edge of the insulation material of the elbow of the cold and heat pipe pipe" in the Republic of China Announcement No. 279493, and its three types As shown in the seventh figure, it is different from the second type of elbow pipe with a smaller radius, and the third type of elbow pipe (5) is covered with insulation material (6) The radius L1 of the rear inner curvature is set to the pipe diameter L2 behind the coating insulation material (6), that is, L1 is equal to L2. Therefore, the curvature of the elbow pipe (5) is relatively large to obtain a better flow of fluid in the delivery pipeline. smooth water effect.

Since when the fluid is transported in the pipeline, the elbow part of the pipeline is often impacted by the fluid turning, so that the junction of the elbow part of the pipeline is often prone to rupture and damage, so the elbow part must be regularly inspected. When inspecting or repairing the pipe body, when you want to inspect and repair the pipe body at the elbow, you must remove the metal sheath and insulation material at that place. The metal sheath and insulation material are usually unusable after dismantling, so With the inspection and maintenance of the pipe body at the elbow, the metal shell and insulation material at the elbow will also be replaced with new ones.

The three different types of elbow assembly will cause changes in the diameter of the pipe after the insulation material is covered, and the specifications and sizes of the different pipe diameters, so the existing industry is based on the three types of assembly of the elbow. For a pipe diameter of one specification, it is necessary to design a protective shell with a corresponding structure for matching. For the manufacturer, it will not only increase the cost of mold opening, but also easily hoard various types of metal protective shells, resulting in The increase of inventory cost and the inconvenience of storage management.

The reason is that the present inventor, in view of the above-mentioned deficiencies in the assembly and use of the outer cladding elbow pipe parts of the existing conveying pipeline, is assisted by his many years of manufacturing and design experience and knowledge in related fields, and through many ingenious ideas, And develop the present invention.

The present invention relates to an outer cladding elbow pipe part of a conveying pipeline, and its main purpose is to provide an outer cladding elbow pipe part of a conveying pipeline that can be used for the assembly of elbow parts of different conveying pipelines with the same protective shell .

In order to achieve the above-mentioned implementation purpose, the inventors have researched the following elbow pipe parts covering the delivery pipeline, which mainly include two semi-circular arc-shaped metal sheaths with the same shape, and make the two sheaths fit together to form a bend Pipe structure, the curved pipe structure includes a first nozzle, a second nozzle and a curved section extending from the first nozzle to the second nozzle, and defines an imaginary through the center of the first nozzle The first axis and a second axis imaginary through the center of the second nozzle, and make the first axis and the second axis together form a 90-degree angle, and make the curved section include a Curved part, and an outer curved part opposite to the inner curved part and located outside the curved section; wherein, the diameter of the first nozzle and the second nozzle is defined as D, and the inner curved part is defined The radius of the curved portion is R1, and the radius of the outer curved portion of the curved section is defined as R2, and R1≥D, and R2≤D/2.

In the above-mentioned elbow pipe part covered with the delivery pipe, at least one serial number is provided on the surface of the protective shell.

As for the above-mentioned outer cladding elbow pipe part of the delivery pipeline, at least one convex rib is respectively formed on the surface of the protective shell adjacent to the first nozzle and the second nozzle.

In the above-mentioned outer covering elbow pipe part of the conveying pipeline, the protective shell is extended with a joint piece on its side.

Thereby, when the two semi-arc-shaped protective shells of the present invention are combined to form an elbow structure to cover the heat insulation material at the elbow of the pipe body of a delivery pipeline, the curved section of the elbow structure can be used to The radius of the inner curved part is greater than or equal to its pipe diameter, and the radius of the outer curved part of the curved section is designed to be less than or equal to 1/2 of the pipe diameter, so that the inner space of the curved pipe structure formed by the two protective shells can be obtained. The best utilization effect, so that the same protective shell can be applied to the assembly types of the elbow parts of different pipelines, so as to effectively save mold opening costs and inventory costs, and improve the convenience of storage management.
