Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a movable docking type reducer. Background Art

[0002] A reducer is a fitting used in chemical pipelines, commonly known as a reducer. It is used to connect two pipes of different diameters and is divided into concentric reducers and eccentric reducers. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the flow rate requirement does not change much, a reducer is required. It is widely used in industrial production and processing and people's daily life.

[0003] At present, conventional reducers are generally fixed by screws during installation, but the joints may need to be disassembled and installed multiple times. Installation with screws is cumbersome and troublesome, and long-term use may cause gaps in the joints, resulting in leakage in the pipeline.

[0026] 2. The utility model proposes a movable docking type reducer. When installing the second water pipe, the second water pipe is aligned and inserted into the first fixed pipe, and the third pull rod is pulled outward to move the arc-shaped clamping plate into the limit groove. At the same time, the arc-shaped clamping plate on the other side moves into the limit groove due to the fourth spring, and then the second pull rod is pulled outward to allow the second water pipe to completely enter the first fixed pipe. When the second pull rod is released, the fifth spring resets the second pull rod, causing the second pull rod to be stuck in the second water pipe. The second water pipe is completely fixed by the arc-shaped clamping plate and the second pull rod. Through the provided clamping mechanism, the water pipe with a smaller diameter can be fixed on the other side of the connecting pipe, and can be quickly disassembled and installed.
