Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to a water supply and drainage device with controllable flow rate. Background Technology
[0002] A city's water supply and drainage network is like its "blood vessels," crucial for its normal operation. During water supply, adjusting the water flow rate allows for the rational allocation of water usage across different areas and time periods, preventing localized water pressure anomalies. For drainage, rapid drainage is necessary during heavy rains, and wastewater treatment plants require precise flow control to ensure efficient processes. However, existing drainage devices often rely on simple valves, only capable of interrupting or roughly adjusting water flow. They cannot detect and adjust dynamically changing drainage volumes in real time. More seriously, these devices lack filtration and cleaning functions, failing to promptly remove impurities, leading to easy pipe blockages and disrupting the normal operation of the drainage system. Utility Model Content
[0003] The main purpose of this utility model is to provide a water supply and drainage device with controllable flow rate, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Screws are threadedly connected to both the right front end and the right rear end of the drainage conversion frame head. A removable filter structure is movably inserted into the filter inlet. A water inlet pressure reduction control structure is fixedly connected to the lower left end of the drainage conversion frame head. The right side of the water inlet pressure reduction control structure extends into the left side of the drainage conversion frame head and is located to the left of the filter inlet. A large drain pipe is fixedly connected to the lower right end of the drainage conversion frame head.
[0006] The water inlet pressure reduction control structure includes a water inlet pipe, which is fixedly connected to the lower left end of the drainage conversion frame head. A control valve is provided on the left side of the outer surface of the water inlet pipe. The right side of the water inlet pipe extends into the drainage conversion frame head and is fixedly connected to a rotating pipe. A drainage diversion and pressure reduction component is fixedly connected to the upper part of the outer surface of the rotating pipe. An outlet pipe is fixedly connected to the right side of the outer surface of the water inlet pipe.

[0008] By adopting the above technical solution: the water inlet pipe is regulated by the control valve. After the water flows into the rotating pipe, the drainage diversion and pressure reduction component plays a role. When the water level rises, the buoyancy ball drives the anti-detachment pin block to move in the anti-detachment sliding groove, so that the diversion pipe diverts and reduces pressure through the diversion water pipe. In conjunction with the outlet pipe, the precise control and reasonable distribution of water flow are achieved, ensuring the stable operation of the device.
[0009] Preferably, the diversion pipe is located above the outlet pipe, the lower end faces of the two anti-slip grooves are lower than the lower end face of the diversion pipe, the two anti-slip pins are respectively matched with the dimensions of the two anti-slip grooves, and the lower end face area of the buoyancy ball is equal to the inner diameter area of the diversion pipe.

[0011] Preferably, the buoyancy ball is slidably connected to the diverter pipe via two anti-detachment pins and two anti-detachment grooves.
[0012] By adopting the above technical solution, the buoyancy ball is slidably connected to the diversion pipe through specific accessories, which can move sensitively with the water level and accurately regulate the water flow, thus achieving effective control of the water flow while ensuring the normal operation of the drainage device.
[0013] Preferably, the removable filter structure includes a filter frame, a handle rod fixedly connected to the upper left part of the filter frame, a snap-fit plate fixedly connected to the middle of the front and rear ends of the filter frame, and a through screw hole opened in the middle of the end of each snap-fit plate away from the filter frame. A waterproof gasket is inserted and fixedly connected to the upper part of the filter frame, a coarse filter screen is inserted and fixedly connected to the lower left end of the filter frame, a medium-sized filter screen is fixedly connected to the middle of the upper inner wall and the middle of the lower inner wall of the filter frame, and several through small filter holes are opened at the right end of the filter frame.
[0014] By adopting the above technical solutions: the handle is easy to pick up, the snap-fit plate and screw holes are easy to fix, the anti-seepage gasket prevents leakage, and the coarse, medium and small filter screens and small filter holes filter impurities in order from large to small, ensuring the quality of the drainage water and ensuring smooth drainage of the device.
[0015] Preferably, the filter frame is movably connected to the drainage conversion frame head via a filter inlet, and the waterproof ring is located directly above the filter inlet and tightly abuts against the upper surface of the drainage conversion frame head.
[0016] By adopting the above technical solution: the filter frame is inserted into the drainage conversion frame head via the filter inlet, which is convenient for installation and disassembly. The anti-seepage gasket is tightly abutted against the frame head, effectively preventing water leakage from the interface and ensuring the sealing and normal operation of the drainage device.
[0017] Preferably, the filter frame is movably snapped to the upper front and upper rear of the drainage conversion frame head by two snap-fit plates, and the two snap-fit plates are detachably connected to the drainage conversion frame head by two screw holes and screws.
[0018] By adopting the above technical solution: the filter frame is movably snapped to the drainage conversion frame head via a snap-fit plate, which facilitates initial positioning and installation. The snap-fit plate is detachably connected to the frame head via screw holes and screws, ensuring a stable connection and facilitating the subsequent disassembly, cleaning, and replacement of the filter frame.
[0019] Preferably, the coarse filter screen is located on the right side of the branch pipe and the outlet pipe.
[0020] By adopting the above technical solution, the coarse filter screen is located on the right side of the branch pipe and the outlet pipe, which can promptly intercept large particles of impurities in the water flow, prevent them from entering the subsequent pipes, effectively protect the branch pipe and the outlet pipe, and ensure smooth drainage.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. In this utility model, the inlet pipe is connected to the drainage conversion frame head for water supply. The control valve can initially adjust the water flow. After the water flows into the rotating pipe, the drainage diversion and pressure reduction component plays a key role. When the water level rises, the buoyancy ball slides in the anti-detachment groove through the anti-detachment pin block under the action of buoyancy. Because the lower end face of the buoyancy ball is compatible with the inner diameter area of the diversion pipe, the water will be diverted out of the diversion pipe when it rises, realizing diversion and pressure reduction. The outlet pipe also participates in drainage at the same time. The two work together to dynamically adjust the drainage speed according to the water level. The overall structure can accurately control the water flow, adapt to different drainage volumes, realize the regulation of water flow speed and pressure, and ensure the stable and efficient operation of the drainage device.
[0023] 2. In this utility model, the filter frame is inserted into the drainage conversion frame head through the filter socket, and is securely installed with the help of the snap-fit plate, screw holes and screws, and is easy to disassemble. The handle makes it easy to pick up the filter frame, and the anti-seepage gasket ensures that the connection is sealed to prevent sewage leakage. The multi-layer filtration design has a coarse filter screen to intercept larger particles of impurities, a medium filter screen to further filter medium-sized impurities, and a small filter hole to filter fine particles, effectively purifying the water flow. It is located on the right side of the branch pipe and the outlet pipe, so that the water can be fully filtered before it enters these pipes, avoiding impurities from entering and causing pipe blockage, thereby ensuring the smooth operation of the entire drainage system, improving drainage quality and the service life of the device.

[0032] Please see Figure 1-4 This utility model provides a technical solution:
[0033] A flow rate controllable water supply and drainage device includes a drainage conversion frame 1. A viewing window 2 is fixedly installed on the left front end of the drainage conversion frame 1. A through filter inlet 3 is opened on the right upper end of the drainage conversion frame 1. Screws 4 are threadedly connected to the right front end and the right rear end of the drainage conversion frame 1. A removable filter structure 5 is movably inserted into the filter inlet 3. A water inlet pressure reduction control structure 6 is fixedly connected to the lower left end of the drainage conversion frame 1. The right side of the water inlet pressure reduction control structure 6 extends into the left side of the drainage conversion frame 1 and is located to the left of the filter inlet 3. A thick drain pipe 7 is fixedly connected to the lower right end of the drainage conversion frame 1.
[0034] In this embodiment, the water inlet pressure reduction control structure 6 includes a water inlet pipe 61, which is fixedly connected to the lower left end of the drainage conversion frame head 1. A control valve 62 is provided on the left side of the outer surface of the water inlet pipe 61. The right side of the water inlet pipe 61 extends into the drainage conversion frame head 1 and is fixedly connected to a rotating pipe 63. A drainage diversion and pressure reduction assembly 64 is fixedly connected to the upper part of the outer surface of the rotating pipe 63. An outlet pipe 65 is fixedly connected to the right side of the outer surface of the water inlet pipe 61. The drainage diversion and pressure reduction assembly 64 includes a diversion pipe 641. Anti-slip grooves 642 are provided on both the front and rear parts of the inner wall of the diversion pipe 641. The right side of the outer surface of the diversion pipe 641... A diversion pipe 645 is fixedly connected to the diversion pipe 641. A buoyancy ball 643 is set directly above the diversion pipe 641. Anti-detachment pins 644 are fixedly connected to the front and rear of the outer surface of the buoyancy ball 643. The diversion pipe 645 is located above the outlet pipe 65. The lower end faces of the two anti-detachment grooves 642 are lower than the lower end face of the diversion pipe 645. The two anti-detachment pins 644 are respectively matched with the dimensions of the two anti-detachment grooves 642. The area of the lower end face of the buoyancy ball 643 is equal to the inner diameter area of the diversion pipe 641. The buoyancy ball 643 is slidably connected to the diversion pipe 641 through the two anti-detachment pins 644 and the two anti-detachment grooves 642.
[0035] Through the above scheme: when water flows into the drainage conversion frame head 1 through the inlet pipe 61, the overall flow rate can be initially adjusted by the control valve 62. After the water flows into the rotating pipe 63, some water will enter the diversion pipe 641 of the drainage diversion and pressure reduction component 64. When the drainage volume increases and the water level rises, the buoyancy ball 643 slides upward in the anti-detachment groove 642 through the anti-detachment pin block 644 under the action of buoyancy. Since the lower end surface area of the buoyancy ball 643 is equal to the inner diameter area of the diversion pipe 641, its rise will cause the water to be diverted out from the diversion pipe 645, realizing diversion and pressure reduction. At the same time, the outlet pipe 65 also continuously drains water. The two work together to dynamically adjust the drainage speed according to the water level. The diversion pipe 645 and the outlet pipe 65 work together to ensure that the drainage device can dynamically adapt to different drainage volumes and ensure the stable and efficient operation of the drainage system.
[0036] In this embodiment, the removable filter structure 5 includes a filter frame 51. A handle 52 is fixedly connected to the upper left part of the filter frame 51. A snap-fit plate 53 is fixedly connected to the middle of the front and rear ends of the filter frame 51. A through screw hole 54 is opened in the middle of the end of each snap-fit plate 53 away from the filter frame 51. A waterproof gasket 58 is inserted and fixedly connected to the upper part of the filter frame 51. A coarse filter screen 55 is inserted and fixedly connected to the lower left end of the filter frame 51. A medium-sized filter screen 56 is fixedly connected to the middle of the upper inner wall and the middle of the lower inner wall of the filter frame 51. Several small filter holes 57 are opened at the right end of the filter frame 51. The filter frame 51 is movably connected to the drainage conversion frame head 1 through the filter inlet 3. The anti-seepage gasket 58 is located directly above the filter inlet 3 and tightly abuts against the upper end face of the drainage conversion frame head 1. The filter frame 51 is movably connected to the upper front and upper rear of the drainage conversion frame head 1 through two snap-fit plates 53. The two snap-fit plates 53 are detachably connected to the drainage conversion frame head 1 through two screw holes 54 and screws 4. The coarse filter screen 55 is located on the right side of the branch water pipe 645 and the outlet water pipe 65.
[0037] Through the above scheme: sewage flows from the drainage conversion frame head 1 into the removable filter structure 5. The sewage first passes through the coarse filter screen 55 to intercept larger particles of impurities, then enters the filter frame 51, where the medium-sized filter screen 56 further filters medium-sized impurities, and finally passes through the small filter hole 57 to filter fine particles. The handle 52 makes it easy to insert or remove the filter frame 51 into the drainage conversion frame head 1 through the filter insertion port 3. The snap-fit plate 53, together with the screw hole 54 and screw 4, fixes the filter frame 51. The anti-seepage gasket 58 ensures that the connection is sealed to prevent sewage leakage. Therefore, through the multi-layer filtration design, the sewage is filtered from coarse to fine, which greatly reduces the possibility of impurities entering the pipe, avoids pipe blockage, and ensures the normal operation of the drainage system. The detachable design makes it easy to remove the filter frame 51 regularly to clean impurities, improves the filtration effect, and extends the service life of the drainage system.
[0038] It should be noted that this utility model is a water supply and drainage device with controllable flow rate. During use, water first flows through the inlet pipe 61 into the drainage conversion frame head 1. The flow rate is initially regulated by the control valve 62. After the water flows into the rotating pipe 63, some water flows to the diversion pipe 641 of the drainage diversion and pressure reduction component 64. When the water level rises, the buoyancy ball 643, relying on buoyancy, slides upwards in the anti-detachment groove 642 through the anti-detachment pin block 644. Because its lower end surface area is equal to the inner diameter area of the diversion pipe 641, it causes water to be diverted from the diversion pipe 645, achieving pressure reduction. This works in conjunction with the outlet pipe 65 to regulate the flow rate. Simultaneously, sewage... Water enters the drainage conversion frame 1, where it passes through a coarse filter screen 55 to intercept large particles of impurities, and then through a medium filter screen 56 and a small filter hole 57 for further filtration. A handle 52 facilitates the removal of the filter frame 51, while a snap-fit plate 53, screw holes 54, and screws 4 are used for fixation. A waterproof gasket 58 ensures a tight seal. Through the coordinated operation of the components in the inlet pressure reduction control structure 6, precise regulation of water flow speed and pressure is achieved to adapt to different drainage volumes. The multi-layer filtration design of the removable filter structure 5 effectively intercepts impurities and prevents pipe blockage. The entire device ensures the stable and efficient operation of the water supply and drainage system, improving drainage quality and efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
