Problems solved by technology

However, setting valves often affects other pipeline branches, and increasing the pipe diameter means that the pipeline needs to occupy more space, which reduces production efficiency and increases product costs

Abstract

The invention relates to an adjustable self-stabilization flow velocity reducer for a pipe. The flow velocity reducer comprises an input mechanism and an output mechanism, wherein a cavity is formed inside after the input mechanism is connected with the output mechanism; a flow inlet is formed in the input mechanism; a flow outlet is formed in the output mechanism; the flow inlet and the flow outlet are respectively connected with the pipe; a speed reducing mechanism is arranged in the cavity, and comprises a main shaft, multiple stoppers arranged at the upper end of the main shaft, a rotating wheel arranged at the lower end of the main shaft, and blades arranged on the rotating wheel; the stoppers are positioned at the back side of the flow inlet; the blades are positioned at the front side of the flow outlet; and the rotating wheel and the blades revolve under the flowing effect of a fluid. Compared with the prior art, the flow velocity reducer uses a method of blocking the flow inlet by the stoppers to realize the negative feedback adjustment between the fluid pressure and the flow velocity so as to realize a function of flow velocity self-stabilization; and included angles between the blades of the rotating wheel and the main shaft of the rotating wheel can be adjusted to change the remainder energy of the fluid in the flow outlet so as to realize the adjustment of the flow velocity in a stable range.

Description

Technical field [0001] The invention relates to a flow rate adjusting device, in particular to an adjustable and self-stabilizing flow rate reducer for pipelines. Background technique [0002] Fluids are ubiquitous in industrial production, including the most widely used water, lubricating oil necessary for the operation of machinery and equipment, and some specific liquids required for production, such as industrial alcohol and concentrated sulfuric acid. In production, the transportation of liquid fluids is often realized by pipelines, but this will cause a problem-the flow and flow rate are not well controlled, often near the source, the high pressure of the liquid and fluid causes the flow and velocity to be large. Providing a specific place with a flow rate and flow rate that meets the requirements without affecting other places is a problem that has always been wanted to be solved in industrial production but has not been solved well. [0003] At present, the general solutio...
