wherein: 1. connecting the pipe body; 2. a first flange joint; 3. a second flange joint; 4. connecting a flange with a hole; 5. an annular seal ring.
Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the utility model briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
This embodiment provides a novel reducing flange joint pipe, including connecting tube body 1 and fixed mounting connect 2 at the first flange of connecting tube body 1 left end and fixed mounting connect 3 at the second flange of connecting tube body 1 right-hand member. Wherein, the internal diameter of first flange joint 2 and second flange joint 3 all equals with the internal diameter of connecting body 1. While the outer diameter of the first flange joint 2 is smaller than the outer diameter of the second flange joint 3.
When encountering the pipeline of different latus rectum and linking to each other, if pipeline A links to each other with pipeline B, pipeline A is different with pipeline B's diameter, and pipeline A's flange is the same with the model of first flange joint 2 in the novel reducing flange connecting pipe of above-mentioned, pipeline B's flange is the same with the model of second flange joint 3 in the novel reducing flange connecting pipe of above-mentioned, then only need when connecting with the flange butt joint of first flange joint 2 in the novel reducing flange connecting pipe of above-mentioned with pipeline A tip, with the second flange joint 3 in the novel reducing flange connecting pipe of above-mentioned with the flange butt joint of pipeline B tip can, at this moment, the fluid in the pipeline A flows into in the pipeline B behind the above-mentioned novel reducing flange connecting pipe.
In order to improve the application range of the novel reducing flange connecting pipe, at least two groups of flange connecting holes 4 are formed in the first flange joint 2 and the second flange joint 3. In this embodiment, two sets of flange connection holes 4 are formed on the first flange joint 2 and the second flange joint 3. Each group of flange connecting holes 4 comprises a plurality of flange connecting holes 4 which are uniformly distributed on the same circumference, and the axis of the circumference is superposed with the axis of the flange joint. In addition, the diameters of the circumferences of the two groups of flange connecting holes 4 on the first flange joint 2 and the second flange joint 3 are different. First flange joint 2 and second flange joint 3 all can dock with two kinds of flange joint of different models through two sets of flange connecting holes 4 to make novel reducing flange joint applicable in the pipeline of multiple different diameters.
