Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to an energy-saving water supply equipment. Background Technology

[0002] Water supply equipment refers to equipment and systems used to provide clean drinking water or industrial water. They typically include components such as water pumps, water tanks, pipes, valves, filters, and water purifiers, used to transport water from water sources to places where water is needed. Among existing energy-saving water supply equipment, there is a type of negative pressure-free variable frequency water supply equipment. This equipment adjusts the pump speed through a frequency converter to match water demand, utilizes municipal residual pressure, and combines a flow stabilizing tank and a vacuum suppressor to achieve negative pressure-free water supply. Furthermore, the main pump of the equipment starts intelligently in rotation, and with the help of a remote pressure gauge for precise pressure adjustment, auxiliary components maintain pressure and prevent shock, achieving efficient and energy-saving water supply.

[0003] Currently, when a vacuum suppressor is installed in the flow stabilization tank of a negative pressure-free variable frequency water supply system, if the water flow state inside the flow stabilization tank is complex (such as turbulence or eddies) or the operating conditions fluctuate greatly, the float below the vacuum suppressor is easily impacted by the water flow and swings abnormally, which can cause the connecting rod behind the float of the vacuum suppressor to deform and fail. This, in turn, affects the stable operation of the negative pressure-free variable frequency water supply system where the vacuum suppressor is located. To address this, we propose an energy-saving water supply system. Utility Model Content

[0004] The main objective of this invention is to provide an energy-saving water supply device. By installing an anti-impact mechanism at the flange pipe above the slow-flow tank of the energy-saving water supply device, and by incorporating an insertion pipe and multiple water inlet buffer structures within the slow-flow tank, a low-impact water flow is provided to the float of the vacuum suppressor. When the water flow, after multiple slow-flow stages, contacts the float of the vacuum suppressor, it will not exert a large impact force on the float, effectively preventing the float below the vacuum suppressor from abnormally swinging and being damaged by the water flow impact. This ensures that the negative pressure-free variable frequency water supply device containing the vacuum suppressor can stably supply energy-saving water, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An energy-saving water supply device includes a slow-flow tank and a vacuum suppressor. The slow-flow tank has an upper flange pipe fixedly connected to its top. It also includes an anti-surge mechanism, which comprises a rubber disc gasket, an insertion pipe, a flange pressure plate, a rubber gasket, a support ring, an inclined baffle, a conical bottom baffle, and a support cylinder. A rubber disc gasket is pressed onto the surface of the upper flange pipe, and a flange pressure plate is pressed onto the surface of the rubber disc gasket. The upper flange pipe, flange pressure plate, and rubber disc gasket are locked together by bolts and nuts. The flange pressure plate has a central opening... The device is integrally formed with an insert tube that is inserted into the upper flange pipe and the slow-flow tank. A support tube is welded to the lower pipe body away from the flange pressure plate. A conical bottom baffle and a support ring are stacked and welded upwards inside the insert tube above the support tube. Inclined baffles for slowing flow are arranged and fixed on the inner ring wall of the support ring. An inclined groove is opened through the central bottom of the conical bottom baffle. A core hole is opened in the center of the bottom of the support tube. A conical cover seat is welded to the support tube above the core hole. An entry groove is opened through the bottom of the support tube outside the conical cover seat.

[0006] Furthermore, a vertical rubber sleeve is integrally formed below the rubber disc pad, which is fitted onto the outside of the insertion tube, and the vertical rubber sleeve is fastened between the inner wall of the insertion tube and the upper flange tube. By adopting the above technical solution, the rubber disc gasket is clamped on the outside of the insertion tube with a vertical rubber sleeve, so that the insertion tube can be sealed when it is inserted into the upper flange tube.

[0007] Furthermore, a rubber gasket is pressed between the flange of the vacuum suppressor and the flange of the upper flange tube, and a through hole for bolts is provided between the rubber gasket, the flange pressure plate, and the rubber gasket. By adopting the above technical solution, after the flange of the vacuum suppressor presses against the rubber gasket and contacts the flange of the upper flange pipe, the bolts can pass through the surface hole of the vacuum suppressor flange, the rubber gasket, the surface hole of the upper flange pipe flange, and the rubber disc gasket and screw on with the nut to complete the flange connection between the vacuum suppressor and the upper flange pipe and the flange pressure plate.

[0008] Furthermore, six sets of water passage grooves are distributed in a ring on the outer wall of the insertion tube, and guide rib blocks are welded and installed in the six sets of water passage grooves. The guide rib blocks are integrally formed on the outer ring surface of the support ring and the cone bottom baffle. By adopting the above technical solution, the inserted pipe can enter the water in the slow-flow tank through the water channel, and the support ring and the cone bottom baffle can be firmly installed by welding in the water channel with the help of the connecting guide block.

[0009] Furthermore, a column is welded to the outer side of the cone-shaped cover of the cone cover seat, and the column of the cone cover seat is welded to the support surface outside the core hole; By adopting the above technical solution, after the cone cover is welded to the surface of the support cylinder with a column, the water in the slow flow tank can also be flushed upward into the insertion pipe through the core hole and the slot of the support cylinder. The water at the core hole is blocked by the cone cover, which buffers the impact force of the water flow into the insertion pipe.

[0010] Furthermore, inclined grooves for water passage are reserved between the inclined baffles within the support ring; By adopting the above technical solution, the inclined baffle in the support ring can buffer the impact force of the water flow after water passes through, thanks to the inclined trough position.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides an anti-impact mechanism by installing a flange pipe above the slow-flow tank of the energy-saving water supply equipment. The anti-impact mechanism is set up with an insertion pipe and multiple water inlet buffer structures in the slow-flow tank, thereby providing a low-impact water flow to the float of the vacuum suppressor. When the water flow after multiple slow-flows comes into contact with the float of the vacuum suppressor, it will not generate a large impact force on the float of the vacuum suppressor, effectively preventing the float below the vacuum suppressor from being damaged by abnormal swinging due to water flow impact, and ensuring that the negative pressure variable frequency water supply equipment where the vacuum suppressor is located can stably supply energy-saving water. Furthermore, when the insertion tube of the anti-impact mechanism is inserted into the upper flange tube, a rubber sleeve is used for sealing. At the same time, there are rubber disc gaskets and rubber joint gaskets pressed between the flange pressure plate of the insertion tube and the flange of the upper flange tube and the vacuum suppressor, ensuring the sealing performance of the upper flange tube, vacuum suppressor and anti-impact mechanism after assembly.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4 As shown, an energy-saving water supply device includes a slow-flow tank 1 and a vacuum suppressor 3. The top of the slow-flow tank 1 is fixedly connected to an upper flange pipe 2. It also includes an anti-rush mechanism 4, which comprises a rubber disc gasket 5, an insertion pipe 7, a flange pressure plate 8, a rubber gasket 9, a support ring 11, an inclined baffle 12, a conical bottom baffle 14, and a support cylinder 16. A rubber disc gasket 5 is pressed onto the surface of the upper flange pipe 2, and a flange pressure plate 8 is pressed onto the surface of the rubber disc gasket 5. The upper flange pipe 2, the flange pressure plate 8, and the rubber disc gasket 5 are locked together by bolts and nuts. The central opening of the flange pressure plate 8 is integrally formed. An insertion tube 7 is inserted into the upper flange pipe 2 and the slow-flow tank 1. A support cylinder 16 is welded to the lower pipe body of the insertion tube 7 away from the flange pressure plate 8. A conical bottom baffle 14 and a support ring 11 are stacked and welded upwards inside the insertion tube 7 above the support cylinder 16. Inclined baffles 12 for slowing flow are arranged and fixed on the inner ring wall of the support ring 11. An inclined groove 15 is opened through the central bottom of the conical bottom baffle 14. A core hole 17 is opened in the center of the bottom of the support cylinder 16. A conical hood seat 18 is welded to the support cylinder 16 above the core hole 17. An entry groove 19 is opened through the bottom of the support cylinder 16 outside the conical hood seat 18.

[0019] Among them, the rubber disc pad 5 has an integrally formed lower part of the disc pad, which is fitted onto the outside of the insertion tube 7, and the rubber disc pad 6 is clamped between the inner tube wall of the insertion tube 7 and the upper flange tube 2. By adopting the above technical solution, the rubber disc gasket 5 is clamped to the outside of the insertion tube 7 with the vertical rubber sleeve 6, so that the insertion tube 7 and the upper flange tube 2 can be installed in a sealed manner.

[0020] Among them, a rubber gasket 9 is pressed between the flange of the vacuum suppressor 3 and the flange of the upper flange pipe 2, and a through hole for bolts is opened between the rubber gasket 9, the flange pressure plate 8 and the rubber disc gasket 5. By adopting the above technical solution, after the flange of the vacuum suppressor 3 presses against the rubber gasket 9 and contacts the flange of the upper flange pipe 2, the bolt can pass through the flange surface hole of the vacuum suppressor 3, the rubber gasket 9, the flange surface hole of the upper flange pipe 2 and the rubber disc gasket 5 and be screwed with the nut to complete the flange connection between the vacuum suppressor 3 and the upper flange pipe 2 and the flange pressure plate 8.

[0021] Among them, six sets of water passage grooves 10 are distributed in a ring on the outer wall of the insertion tube 7, and guide rib blocks 13 are welded and installed in the six sets of groove cavities of the water passage grooves 10. The guide rib blocks 13 are integrally formed on the outer ring surface of the support ring 11 and the cone bottom baffle 14. By adopting the above technical solution, the insertion pipe 7 can enter the water in the slow-flow tank 1 through the water channel 10, and the support ring 11 and the cone bottom baffle 14 can be firmly installed by welding in the water channel 10 with the help of the guide rib block 13.

[0022] Among them, the cone-shaped cover of the cone cover 18 is welded with a column on the outside of the cone-shaped cover body, and the column of the cone cover 18 is welded on the surface of the support cylinder 16 outside the core hole 17. By adopting the above technical solution, after the cone cover seat 18 is welded to the surface of the support cylinder 16 with the column, the water in the slow flow tank 1 can also be rushed upward into the insertion tube 7 through the core hole 17 and the slot 19 of the support cylinder 16. The water at the core hole 17 is blocked by the cone cover seat 18, which buffers the impact force of the water flow into the insertion tube 7.

[0023] Among them, the inclined baffles 12 inside the support ring 11 are reserved with inclined grooves for water passage; By adopting the above technical solution, the inclined baffle 12 inside the support ring 11 can buffer the impact force of the water flow after water passes through, thanks to its inclined groove position.

[0024] It should be noted that this utility model is an energy-saving water supply device. By setting an anti-collision mechanism 4 at the flange pipe 2 above the slow-flow tank 1 of the energy-saving water supply device, the rubber disc gasket 5 of the anti-collision mechanism 4, together with the vertical rubber sleeve 6, is fitted under the insertion pipe 7. At this time, the rubber disc gasket 5 is in contact with the lower plate surface of the flange pressure plate 8. After the insertion pipe 7 with the vertical rubber sleeve 6 is inserted into the upper flange pipe 2, the flange pressure plate 8 can press the rubber disc gasket 5 and contact the flange of the upper flange pipe 2. At this time, the rubber gasket 9 can press on the surface of the flange pressure plate 8. Subsequently, the vacuum suppressor 3 can press on the surface of the rubber gasket 9, so that the float of the vacuum suppressor 3 can enter the insertion pipe 7 along the rubber gasket 9 and the flange pressure plate 8. At this time, the bolt can pass through the flange surface hole of the vacuum suppressor 3, the rubber gasket 9, the flange surface hole of the upper flange pipe 2, and the rubber disc gasket 5 and be screwed with the nut to complete the flange connection between the vacuum suppressor 3 and the upper flange pipe 2 and the flange pressure plate 8. When water is flushed into the slow-flow tank 1 for water supply, the water flow can slowly enter the insertion pipe 7 along the core hole 17 and the slot 19 of the support cylinder 16. At the same time, the water flow is guided into the insertion pipe 7 by the water passage 10. The water at the core hole 17 is blocked by the cone cover seat 18, which buffers the impact force of the water flow into the insertion pipe 7. When the water in the cavity of the insertion pipe 7 comes into contact with the float of the vacuum suppressor 3, the water flow in the insertion pipe 7 flows slowly again along the inclined groove 15 of the cone bottom baffle 14, and finally flows slowly upward into the insertion pipe 7 between the inclined baffles 12 in the support ring 11. When the water flow after multiple slow flows comes into contact with the float of the vacuum suppressor 3, it will not generate a large impact force on the float of the vacuum suppressor 3, preventing the float below the vacuum suppressor 3 from being damaged by abnormal swinging due to the impact of the water flow, and ensuring that the vacuum suppressor 3 is located in the negative pressure-free variable frequency water supply equipment to stably supply energy-saving water.
