Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage, specifically to a water supply and drainage device that facilitates flow adjustment. Background Technology
[0002] Water supply and drainage generally refers to urban water supply systems, drainage systems, municipal water supply and drainage, and building water supply and drainage, abbreviated as water supply and drainage. Water supply and drainage refers to the organic integration of urban water supply, sewage treatment, drainage and water conservation, and the unified management of urban water resource development, utilization and protection. Water supply equipment refers to the water supply system installed in a building, including equipment components such as water tanks, water pumps, and water pipes. Its function is to provide clean and hygienic tap water to provide water services for the living and production of users in the building.
[0003] A search revealed a water supply and drainage filtration device with publication number CN220214211U. Specifically, the device includes a pipe body and an anti-clogging mechanism. The anti-clogging mechanism comprises a drive assembly, a sliding groove, a filter screen, and a cleaning pipe. The drive assembly provides sliding conditions for the sliding groove to move the filter screen, and the cleaning pipe provides replacement conditions for the filter screen. When the filter screen is replaced, the drive assembly drives the sliding groove to slide, and the sliding groove moves the filter screen closer to the cleaning pipe. Finally, the filter screen is removed from the sliding groove by hand through the cleaning pipe, thus achieving filter screen disassembly and solving the problem of filter disassembly.
[0004] Existing water supply and drainage systems lack the ability to easily adjust flow rates, requiring manual rotation or raising of valve cores to change the flow area. Moreover, the adjustment range is limited and non-linear. The water supply and drainage system in the comparative case mentioned above also lacks the ability to easily adjust flow rates. Thus, in order to maintain a stable flow rate over a long period of time, it is necessary to continuously run the water pump or throttle the flow through the valve, thereby increasing the energy consumption of the water supply and drainage system and making it unsuitable for occasions with intermittent water use.
[0005] Therefore, it is necessary to invent a water supply and drainage device that is easy to adjust the flow rate to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a water supply and drainage device that facilitates flow regulation. Through a downstream regulating pipe, regulating ring, horizontal plate, first push rod, flow plug, second push rod, and flow cage, the device achieves the ability to easily regulate flow. This automatic flow regulation avoids the flow deviation caused by the lag in manual adjustment of traditional valves. Furthermore, precise matching of flow and clearance is achieved through mechanical linkage, adapting to complex operating conditions. This design, with its automatic mechanical adjustment, eliminates the need for continuous energy consumption, making the device suitable for intermittent water use scenarios. The overall automated adjustment reduces labor costs, addressing the problem that existing water supply and drainage devices lack the ability to easily regulate flow. This requires manual rotation or raising / lowering of the valve core to change the flow area, and the adjustment range is limited and non-linear. Furthermore, the water supply and drainage devices in the aforementioned comparative cases also lack this ability. Under long-term use, to maintain stable flow, continuous operation of the water pump or valve throttling is required, increasing energy consumption and making the device unsuitable for intermittent water use.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a water supply and drainage device that facilitates flow adjustment, including a water supply and drainage tank, which is the main body for treating sewage and mixed water;
[0008] The water inlet pipes are all fixedly installed above the water supply and drainage tank to assist water inlet. A downstream regulating pipe is fixedly installed at the bottom of the water supply and drainage tank. An regulating ring is fixedly installed inside the downstream regulating pipe. A horizontal plate is fixedly installed above the regulating ring. A first push rod is slidably connected inside the horizontal plate.
[0009] A flow plug is fixedly installed at the bottom of the first push rod for the first push rod to push the flow plug. Fixing blocks are fixedly installed on both sides of the flow plug. A second push rod is fixedly installed at the bottom of the flow plug. A flow squirrel cage is hinged to the bottom of the second push rod. An outer fixing ring is fixedly installed inside the lower part of the downstream regulating pipe.
[0010] The mounting block is fixedly installed on both sides inside the downstream regulating pipe. It is used to fix a waterproof sealing cylinder above it, and a waterproof nitrogen spring is fixedly installed inside the waterproof sealing cylinder. The top end of the waterproof nitrogen spring is fixedly connected to the bottom of the mounting block.
[0011] Preferably, a water supply and drainage filter screen is fixedly installed inside the water supply and drainage tank, and a sludge collection filter box is fixedly installed at the bottom of the water supply and drainage filter screen.
[0012] Preferably, a telescopic cylinder is fixedly installed on the outside of the water supply and drainage tank, and a dirt scraper is fixedly installed at the front end of the telescopic cylinder, and the dirt scraper is slidably connected to the water supply and drainage tank.
[0013] Preferably, the adjusting ring is slidably connected to the flow plug, and the flow cage is slidably connected to the outer fixing ring.
[0014] Preferably, a manifold is fixedly installed at the bottom end of the downflow regulating pipe, a water supply and drainage discharge pipe is fixedly installed at the other end of the manifold, and a water supply and drainage purification box is fixedly connected to the other end of the water supply and drainage discharge pipe.
[0015] Preferably, each of the water supply and drainage purification boxes has a purification filter bag fixedly installed inside, and a water supply pipe is fixedly installed outside the water supply and drainage purification box.
[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0017] This utility model includes a downstream regulating pipe, an regulating ring, a horizontal plate, a first push rod, a flow plug, a second push rod, and a flow cage. When using this water supply and drainage device, as the flow rate of the water entering the water supply and drainage tank increases, the water directly impacts the flow plug on the downstream regulating pipe. The flow plug slides vertically down via the first push rod, simultaneously driving the flow cage down within the outer fixed ring via the second push rod, thereby widening the gap for the water supply and drainage to flow out of the downstream regulating pipe. When the inflow rate decreases, the waterproof nitrogen spring compressed by the sliding flow plug will cause the flow plug to rise towards the regulating ring. In this way, the flow plug and the flow cage together reduce the flow gap of the water supply and drainage, giving the water supply and drainage device the ability to easily regulate the flow rate. This automatic flow regulation avoids the flow deviation caused by the lag in manual adjustment of traditional valves. Moreover, the precise matching of flow rate and gap is achieved through mechanical linkage, adapting to complex working conditions. At the same time, this design for easy flow regulation, through automatic adjustment of the mechanical structure, requires no continuous energy consumption, making the water supply and drainage device suitable for intermittent water use scenarios. The overall automatic adjustment also reduces labor costs. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The water supply and drainage device shown includes a water supply and drainage tank 1, which is the main body for treating sewage and mixed water.
[0028] The water inlet pipe 2 is fixedly installed above the water supply and drainage box 1 to assist water inlet. The bottom of the water supply and drainage box 1 is fixedly installed with a downstream regulating pipe 7. An regulating ring 8 is fixedly installed inside the downstream regulating pipe 7. A horizontal plate 9 is fixedly installed above the regulating ring 8. A first push rod 10 is slidably connected inside the horizontal plate 9.
[0029] A flow plug 11 is fixedly installed at the bottom of the first push rod 10 and is used by the first push rod 10 to push the flow plug 11. Fixing blocks 12 are fixedly installed on both sides of the flow plug 11. A second push rod 13 is fixedly installed at the bottom of the flow plug 11. A flow cage 14 is hinged to the bottom of the second push rod 13. An outer fixing ring 15 is fixedly installed inside the lower part of the downstream regulating pipe 7.
[0030] Mounting block 16 is fixedly installed on both sides inside the downstream regulating pipe 7. A waterproof sealing cylinder 17 is fixedly installed above it. A waterproof nitrogen spring 18 is fixedly installed inside the waterproof sealing cylinder 17. The top of the waterproof nitrogen spring 18 is fixedly connected to the bottom of the fixing block 12. When the inlet water flow decreases, the waterproof nitrogen spring 18, which is compressed by the sliding flow plug 11, will drive the flow plug 11 to rise towards the regulating ring 8. In this way, the flow plug 11 and the flow cage 14 together reduce the flow gap of water supply and drainage, so that the water supply and drainage device has the ability to easily adjust the flow.
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a water supply and drainage filter screen 3 is fixedly installed inside the water supply and drainage tank 1. A dirt collection box 4 is fixedly installed at the bottom of the water supply and drainage filter screen 3. The double-layer water supply and drainage filter screen 3 is used to filter sewage and mixed water when water enters the water supply and drainage tank 1, thereby improving the water quality of the water supply and drainage. A telescopic cylinder 5 is fixedly installed on the outside of the water supply and drainage tank 1. A dirt scraper 6 is fixedly installed at the front end of the telescopic cylinder 5. The dirt scraper 6 is slidably connected to the water supply and drainage tank 1. Under long-term use, the telescopic cylinder 5 can drive the dirt scraper 6 to scrape off the dirt on the water supply and drainage filter screen 3. The water is pushed into the sludge collection filter box 4 to ensure the filtration effect of the water supply and drainage filter screen 3. The regulating ring 8 is slidably connected to the flow plug 11, and the flow cage 14 is slidably connected to the outer fixed ring 15. As the flow rate of the water supply and drainage entering the water supply and drainage tank 1 increases, the water will directly impact the flow plug 11 of the downstream regulating pipe 7. The flow plug 11 slides vertically down through the first push rod 10, and simultaneously drives the flow cage 14 to slide down in the outer fixed ring 15 through the second push rod 13, thereby expanding the gap of the water supply and drainage flowing out of the downstream regulating pipe 7.
[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a manifold 19 is fixedly installed at the bottom of the downflow regulating pipe 7, and a water supply and drainage discharge pipe 20 is fixedly installed at the other end of the manifold 19. A water supply and drainage purification box 21 is fixedly connected to the other end of the water supply and drainage discharge pipe 20. The water supply and drainage purification box 21 can store the water supply and drainage flowing out from the downflow regulating pipe 7 and perform secondary filtration and purification on the water supply and drainage before use. Purification filter bags 22 are fixedly installed inside the water supply and drainage purification box 21, and a water supply pipe 23 is fixedly installed outside the water supply and drainage purification box 21. The overall structure of the purification filter bags 22 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to maintain or replace them in a timely manner.
[0033] The working principle of this utility model is as follows: First, the inlet pipe 2 is connected to the external sewage and mixed water pipes, allowing the sewage and mixed water to enter the water supply and drainage tank 1. The water supply and drainage tank 1 is equipped with two layers of water supply and drainage filters 3 to filter the incoming water supply and drainage. As the flow rate increases, the water directly impacts the flow plug 11 of the downstream regulating pipe 7. The flow plug 11 then slides vertically down via the first push rod 10, and simultaneously, via the second push rod 13, it drives the flow cage 14 to slide down within the outer fixed ring 15, thereby widening the gap in the flow of water supply and drainage through the downstream regulating pipe 7. Subsequently, when the inlet flow rate decreases, the waterproof nitrogen spring 18, compressed by the sliding flow plug 11, causes the flow plug 11 to return to its original position and rise towards the regulating ring 8. In this way, the flow plug 11 and the flow cage 14 together reduce the flow gap in the water supply and drainage, making the water supply and drainage device easily adjustable. The automatic flow regulation of this device avoids the flow deviation caused by the lag in manual adjustment of traditional valves. Furthermore, it achieves precise matching of flow and clearance through mechanical linkage, adapting to complex operating conditions. This easy-to-adjust flow design, through automatic adjustment of the mechanical structure, eliminates the need for continuous energy consumption, making the water supply and drainage device suitable for intermittent water use scenarios. The overall automatic adjustment reduces labor costs. The water supply and drainage, after primary filtration through the downstream regulating pipe 7, then passes through the manifold 19 and the water supply and drainage discharge pipe 20 into the water supply and drainage purification tank 21. The purification tank 21 contains multiple purification filter bags 22, allowing for secondary purification and filtration of the water supply and drainage before use, thereby improving water quality. Finally, after completing the installation and use of the entire water supply and drainage device according to the above operations, routine maintenance is required. This completes the usage process of the easily adjustable flow water supply and drainage device.
[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
