Description

Technical Field

[0001] The invention relates to the technical field of fluid pipelines, and in particular to a water impact regulating device for a water supply pipeline. Background Art

[0002] In water supply pipelines, water hammer effect is a hydraulic phenomenon accompanied by sharp fluctuations in fluid pressure and flow rate, usually caused by the closing and opening of valves in the pipeline system, the starting and stopping of water pumps, and the sudden stopping of turbines. When an open valve is suddenly closed or the water supply pump stops, the water flow will generate a pressure on the valve and pipe wall, mainly the valve or pump. Due to the smooth pipe wall, the subsequent water flow quickly reaches the maximum hydraulic force under the action of inertia and produces a destructive effect. This is the "water hammer effect" in hydraulics, called positive water hammer. On the contrary, a closed valve will also produce water hammer after it is suddenly opened or the water supply pump is started, which is called negative water hammer.

[0003] In order to prevent the harm caused by the water hammer effect, a piston-type buffer mechanism is installed on the water supply pipeline to buffer the force of water flow impacting the surrounding pipe walls. When the valve or water pump is suddenly closed and the water flow rate is fast, most of the water flow cannot enter the interior of the piston-type buffer mechanism in time, resulting in the water supply pipeline still needing to withstand a large impact force, and the ability to eliminate the water hammer effect needs to be improved. Therefore, the present application proposes a water shock regulating device for a water supply pipeline. Summary of the invention

[0018] Please combine Figures 1 to 9 As shown, the present invention provides a water impact regulating device for a water supply pipeline, comprising a piston cylinder 12 and a piston plate 14 slidably arranged inside the piston cylinder 12, a hydraulic gauge 121 and a vent 122 are fixedly installed on the top of the piston cylinder 12, the pressure of the cavity above the piston plate 14 inside the piston cylinder 12 can be adjusted through the vent 122, and the hydraulic gauge 121 detects the pressure of the cavity above the piston plate 14 inside the piston cylinder 12, and the water impact regulating device also includes: The outer cylinder 10 is fixedly mounted on the bottom end of the piston cylinder 12, and the outer cylinder 10 is connected to the inside of the piston cylinder 12. A pair of inner tubes 11 are fixedly mounted inside the outer cylinder 10, and flanges 111 are fixedly mounted on one end of the two inner tubes 11. The water impact adjustment device is fixedly mounted on the water supply pipeline through the flanges 111. A plurality of inclined tubes 13 are fixedly mounted on one of the inner tubes 11. The top ends of the plurality of inclined tubes 13 are connected to the inside of the piston cylinder 12, and the top ends of the inclined tubes 13 are located below the piston plate 14. The water flows normally in the pipeline. When the water flows, the pressure of the cavity above the piston plate 14 is greater than the normal water pressure. The piston plate 14 closes the top ends of the plurality of inclined tubes 13. When the water pump or valve is suddenly closed, the water pressure in the pipeline increases rapidly. At this time, the water pressure is greater than the pressure of the cavity above the piston plate 14. The water flow can enter the cavity below the piston plate 14 through the inclined tube 13, causing the piston plate 14 to move upward to buffer the water impact. The inclined tube 13 is set to an inclined state, and the end of the inclined tube 13 faces the flow direction of the water flow, which is conducive to the rapid entry of the water flow into the inclined tube 13, and the effect of eliminating the water impact is better. A plurality of rotating plates 21 are provided and are located between the two inner tube bodies 11, and the plurality of rotating plates 21 are evenly spaced and distributed in the circumferential direction of the inner tube body 11; The fitting blocks 22 are provided in plurality and are all fixedly mounted on one end of an inner tube body 11. The fitting blocks 22 are evenly spaced and distributed in the circumferential direction of the inner tube body 11. The plurality of rotating plates 21 and the plurality of fitting blocks 22 are combined into a cylindrical shape. A first annular frame is fixedly mounted on the inner surface of the outer cylinder 10, and a plurality of rotating plates 21 are rotatably mounted on the first annular frame, and a torsion spring 26 is fixedly arranged between each rotating plate 21 and the first annular frame; The second annular frame is slidably mounted on the inner surface of the outer cylinder 10, and a plurality of rotating rods 24 are rotatably mounted on the second annular frame. The plurality of rotating rods 24 correspond to the plurality of rotating plates 21 one by one, and the rotating rods 24 are rotatably connected to one end of the rotating plate 21; The first transmission assembly is fixedly installed between the piston plate 14 and the second annular frame. The first transmission assembly is configured so that when the piston plate 14 rises, the second annular frame slides to rotate the multiple rotating plates 21, and when the rotating plates 21 stop rotating, the piston plate 14 can continue to rise. With regard to the above structure, when the valve or water pump is suddenly closed, the water pressure in the pipeline increases rapidly, and the water flow enters the cavity below the piston plate 14 through the inclined tube 13. At this time, the piston plate 14 moves toward the top of the piston cylinder 12. During the rising process of the piston plate 14, the second annular frame slides inside the outer cylinder 10 under the action of the first transmission assembly, so that the multiple rotating plates 21 rotate into an inclined state, and part of the area of ​​the multiple rotating plates 21 is located in the inner tube On the inner side of the body 11, part of the water flowing inside the inner tube body 11 will hit the rotating plate 21, and the rotating plate 21 will guide the water flow to the cavity below the piston plate 14 to avoid that after the water pressure increases rapidly, the water flow cannot enter the cavity below the piston plate 14 in time, resulting in the water supply pipeline still needing to withstand a large impact force, affecting the service life of the water supply pipeline. Using multiple rotating plates 21 to guide the water flow to the cavity below the piston plate 14 can speed up the elimination of the water impact force and better protect the water supply pipeline. After the water impact is eliminated, the water pressure in the pipeline returns to normal. At this time, the pressure in the cavity above the piston plate 14 is greater than the water pressure in the pipeline, and the piston plate 14 moves downward to close the top of the inclined tube 13.
