Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a device for reducing outlet flow velocity. Background Art

[0002] The water flow rate in the pipeline refers to the speed at which water flows in the pipeline, which is usually measured by the flow rate of water passing through the pipeline per unit time.

[0025] Here’s how it works:

[0026] First, connect the pipe body 1 to the drainage pipe and wait for drainage to start;

[0027] Second, when drainage begins, the water flows through the pipe body 1 to the outlet pipe 2, and the water flows through the buffer block 31 for initial buffering to achieve the effect of reducing the flow rate, and then reaches the buffer plate 362 for further buffering, and then is discharged. The baffle 33 can prevent the water from flowing out of the adjustment groove 361, and the baffle 33 moves along the limit groove 35 through the limit rod 34 to achieve comprehensive shielding;

[0028] Third, when the flow rate needs to be adjusted, pull the connecting rod 367 to pull the connecting rod 367 out of the fixed rod 368, and then pull the connecting rod 367 upward to fix the connecting rod 367 on the previous fixed rod 368. When the connecting rod 367 moves, it drives the connecting block 365 to move through the hinge 366. When the connecting block 365 moves, it drives the left end of the buffer plate 362 to move, so that the buffer plate 362 rotates along the fixed axis 363. When the left end of the buffer plate 362 rises, the right end of the buffer plate 362 drops, thereby adjusting the angle of the buffer plate 362 and then realizing the adjustment of the flow rate.
