[0002] The pipeline switching device is a device for diverting, converging or switching flow directions. Under high pressure and large diameter conditions, the pipeline switching device reduces the number of connecting bolts of the valve body itself, thereby enhancing the reliability of the valve and overcoming the influence of the system's deadweight on the normal operation of the valve. The pipeline switching device is widely used as a medium switching device in pipelines in coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceutical industry, etc.

[0003] In the prior art, since a pipeline switching device is often used in the chemical production process, and the pipeline switching device is composed of a feed port, a switching hose, a sealing strip, a discharge port and a cylinder, when the pipeline switching device is used, the switching hose is driven by the cylinder, and the switching hose is brought into contact with different discharge ports according to the operation of the cylinder, thereby realizing the switching of the pipeline. However, when the pipeline switching device is used, since the pipeline switching device is driven by the cylinder to connect the switching hose with different discharge ports to achieve the switching of the pipeline, since the end of the switching hose is in contact with the sealing strip, when the cylinder switches the position of the switching hose, there will be a deviation because the position of the switching hose when it moves is not vertically corresponding to the position of the discharge port, resulting in leakage problems when the pipeline is switched.

The sealing of the switching device uses an airtight ring. The switching hoses of the feed port and the discharge port 301 of the switching device are connected by a steel wire hose.

[0024] The top of the hose interface 201 is fixedly installed with a mouth ring 4, the side of the mouth ring 4 is fixedly connected to a side block 401, the top of the side block 401 is fixedly connected to an end block 402, the bottom of the end block 402 is fixedly connected to a clamping rod 403, the bottom end of the end block 402 contacts a gasket 404, the bottom surface of the gasket 404 is fixedly connected to an arc plate 405, the inner wall of the arc plate 405 is fixedly connected to an outer plate 406, the inner wall of the hose interface 201 is fixedly arranged with a wall panel 5, the inner wall of the wall panel 5 is fixedly provided with a stop block 501, and the bottom end of the surface of the hose interface 201 is fixedly installed with a fixed gasket 6.

[0025] The end of the mouth ring 4 contacts the sealing strip, which seals the top of the two discharge ports 301 where they meet the hose interface 201. The mouth ring 4 is located at the top of the hose interface 201, and the center of the mouth ring 4 has a groove that matches the shape of the hose interface 201.

At this time, the frame plate 7 can be fixed to the surface of the cylinder 3 by means of the block 701 and the protrusion 702. At the same time, when the cylinder 3 is operating, the position of the frame plate 7 on the surface of the cylinder 3 can be adjusted according to the frequency of vibration, so that the position of the cylinder 3 during use is more stable.
