Abstract
The utility model discloses a non-welding, special-shaped, transitional connecting pipe fitting, which comprises a connecting pipe fitting body, provided with a large-diameter connecting pipe on one end and a small-diameter connecting pipe on the other end, and a variable diameter conical pipe inside the pipe fitting which can communicate the large-diameter connecting pipe with the small-diameter connecting pipe. With the application of the technological scheme, a uniform and smooth surface can be formed on the intracavity of the utility model. Moreover, the fibrous tissues of the interior metal of the utility model is continuous and the pressure bearing capacity has risen by over 50% compared with the existing welding components at home because of the integrated forging and shaping. Therefore, compared with the existing technologies, the utility model has the advantages of easier manufacture, lower production cost, steadier working performance, higher safety and reliability, etc.
Description
Technical field
The utility model relates to a kind of high temperature of thermal power generation conveying, special-shaped transition connection pipe fitting of welding-free type of pressure duct of being used for, and belongs to thermal power generation and carries high temperature, high-pressure control device technical field.
Background technique
The transition connection pipe fitting is important, the key structure spare in the thermal power generation boiler high temperature and high pressure steam line transportation, its effect mainly is that the ultra-high temperature, the transition in the hyperpressure pipeline that are used for thermal power generation boiler delivery of steam process connect, and plays the shunting transition, ensures proper functioning, ensures its Safety performance.At present domestic transition tube mainly adopts the segmentation processing welding fabricated structure that forms of assembly welding again.Inner chamber butt welding place of this structure is a trapezoidal faces, and a ring-type weld seam arranged in its structure, the transition tube of this welding fabricated structure, the mass stability of its weld seam and welding heat affected zone is difficult to guarantee, reliability is low, because of its inner chamber is not the structure of uniformity smooth surface, reduced its working life greatly.Therefore existing transition fitting have that manufacturing process is various, complex process, the process-cycle is long, cost is high shortcoming, particularly group welding piece its withstand voltage poor safety performance in the course of the work, equipment and life security incident take place easily.
Summary of the invention
The purpose of this utility model is: provide a kind of welding-free type abnormal shape transition connection pipe fitting easy, that manufacture cost is lower, working life is long, service behaviour is safe and reliable of making, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises connection pipe fitting body (4), end at connection pipe fitting body (4) is provided with major diameter connecting tube (1), the other end at connection pipe fitting body (4) is provided with minor diameter connecting tube (2), and is provided with the reducing Taper Pipe (3) that major diameter connecting tube (1) and minor diameter connecting tube (2) can be interconnected in connection pipe fitting body (4); Connection pipe fitting body (4) is the integrated type pipe fitting body of no soldered; The internal diameter of major diameter connecting tube (1) is than the big 300～500mm of internal diameter of minor diameter connecting tube (2), and the external diameter of major diameter connecting tube (1) is than the big 400～600mm of external diameter of minor diameter connecting tube (2); The length of major diameter connecting tube (1) and minor diameter connecting tube (2) is 200～250mm.
Owing to adopted technique scheme, inner chamber of the present utility model forms uniform and smooth surface, and owing to adopt integral forging and forming, the fibrous structure of its interior metal is continuous, the raising that bearing capacity is shaped than domestic existing weld assembly more than 50%.Therefore, the utility model compared with prior art, have make easily, manufacture cost is lower, stable work in work, advantage such as safe and reliable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the side's of employing ingot or octagon ingot are made connection pipe fitting body (4), with at the bottom of steel ingot remove feeders, the ingot and after the heating, use the drift punching, one end of jointed tubular workpieces body (4) is made into major diameter connecting tube (1), the other end of jointed tubular workpieces body (4) is made into minor diameter connecting tube (2), and the length of major diameter connecting tube (1) and minor diameter connecting tube (2) is 200～250mm; Produce reducing Taper Pipe (3) between major diameter connecting tube (1) and the minor diameter connecting tube (2), heat-treat then, obtain not having the integrated type pipe fitting body of soldered; Wherein, the internal diameter of major diameter connecting tube (1) is than the big 300～500mm of internal diameter of minor diameter connecting tube (2), and the external diameter of major diameter connecting tube (1) is than the big 400～600mm of external diameter of minor diameter connecting tube (2).
