A rotor ring structure for water hammer effect elimination device

Abstract

The invention discloses a rotor ring structure for a water hammer effect elimination device, which discloses a rotor ring structure that forms a helical turbulence through a helical spoiler to helically disturb the impacting water flow and improve the turbulence effect, and is characterized in that two sets of helical turbulence The plates are respectively placed on both sides of the rotor ring, and a group of said spiral spoilers are composed of at least three spiral spoilers distributed at equal angles, said spiral spoilers are spiral plates, and the spiral spoilers The thickness gradually decreases from both sides of the middle part to form an arc-shaped surface, the arc-shaped surface is provided with brushes, the spiral spoiler is provided with through holes, and the inner wall of the spiral spoiler is embedded with at least two reinforcements. Silk.

Description

technical field [0001] The invention relates to a rotor ring structure for a water hammer effect eliminating device, which relates to a rotor ring structure used in a water hammer effect eliminating device, and belongs to the field of hydraulic engineering. In particular, it relates to a rotor ring structure that forms a helical turbulent flow through a helical spoiler to perform helical perturbation of the impinging water flow and improves the effect of the turbulent flow. Background technique [0002] The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow will be under the action of inertia. In the prior art, a piston buffer mechanism is set on the side of the valve pipeline to impact the surrounding pipe wall. However,...

Problems solved by technology

[0002] The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, mainly because the valve will generate a pressure. This is the so-called "water hammer effect" in hydraulics. In the prior art, a piston buffer mechanism is set on the side of the valve pipe to impact against the surrounding pipe walls. However, due to the limited arrangement and number of pistons, it is impossible to wrap and decompress the entire circumferential surface of the pipeline, resulting in slow buffering efficiency for water hammer force and unsatisfactory decompression effect.

[0003] A water hammer effect elimination device designed by the applicant to solve the above problems, including water inlet connecting pipe, main body, rotor ring with diverter plate, pressure relief cylinder, protective cover, water outlet connecting pipe and other structures, and in design and use It is found that because the splitter plate of the rotor ring is a simple flat plate structure, due to its light weight and thin thickness, when the rotor ring rotates, the splitter plate has a poor ability to disturb the water flow impacting around the tube wall, and cannot effectively and quickly rotate the impacting water flow.
