Technical Field
[0001] This application relates to water meters, and more particularly to a water meter with a multi-diameter interface. Background Technology
[0002] A water meter is a measuring instrument used to measure and record the amount of water flowing through it. It is widely used in various water use scenarios such as households, businesses, and municipal water supply. It is an important tool for realizing reasonable water resource billing, water conservation management, and water supply system monitoring. Water meters can accurately measure water consumption, which greatly improves water supply management. They have been widely used in various water use scenarios such as residential communities, commercial complexes, and industrial plants, and have become an important infrastructure for smart city construction and efficient water resource management.
[0003] Currently, most water meter interfaces on the market adopt a single fixed diameter design. In actual installation and use, due to the different historical evolution and standards of water supply pipelines in different buildings and regions, the outer diameter specifications of the pipelines are complicated, and the water meter interface often does not match the size of the pipeline on site. As a result, construction workers have to use additional fittings such as adapters, reducing flanges or reducers for conversion. This not only increases material costs and inventory management difficulties, but also leads to complicated installation process, extended construction time, and the introduction of multiple potential leakage points. Utility Model Content
[0004] The purpose of this application is to provide a water meter with multiple diameter interfaces, which solves the problem that using additional fittings such as adapters, reducing flanges or reducers to connect to a single fixed diameter water meter not only increases material costs and inventory management difficulty, but also leads to complicated installation procedures, extended construction time, and the introduction of multiple potential leakage points.
[0005] The water meter with a multi-diameter interface provided in this application adopts the following technical solution: it includes a water meter body, a metering module is installed inside the water meter body, a water inlet pipe is fixedly connected to the water inlet of the water meter body, a first sleeve is threaded on the inner side of the water inlet pipe, a second sleeve is fixedly connected to one end of the first sleeve, a plurality of shrink plates are fixedly connected to the end of the first sleeve away from the second sleeve, an adjusting block is fixedly connected inside the water inlet pipe, a sealing gasket is provided inside the first sleeve, a threaded groove is opened on the inner wall of the second sleeve and a clamping nut is threadedly connected, an adjusting ring is sleeved on the outer side of the water inlet pipe, a rotating ring is fixedly connected to one end of the adjusting ring, and a water pipe body is provided inside the water inlet pipe; By adopting the above technical solution, during the use of this device, the operator needs to place the water pipe body inside the first sleeve, so that the water pipe body contacts the adjusting block, and then rotate the adjusting ring to make the rotating ring drive the slider to rotate, thereby causing the second sleeve to drive the first sleeve to move axially along the thread direction inside the water inlet pipe. In this way, the conical structure of the adjusting block forces the shrink plate to shrink, thus completing the fixation of the water pipe body and the water inlet pipe. This solves the problem of using additional fittings such as adapters, reducing flanges or reducing pipes to connect a single fixed diameter water meter, which not only increases material costs and inventory management difficulty, but also leads to complicated installation process, extended construction time, and the introduction of multiple potential leakage points.
[0006] Preferably, the shrink plate is made of spring steel and is evenly distributed circumferentially at one end of the first sleeve; By adopting the above technical solution, the shrink plate is made of spring steel and is evenly distributed around the circumference. By utilizing the good elastic deformation ability and structural strength of spring steel, it is ensured that the shrink plate can shrink stably during the adjustment process to adapt to different pipes, and can also provide a continuous and uniform clamping force to ensure the stability of the pipe connection, while extending the service life of the shrink plate.
[0007] Preferably, the adjusting block is conical in shape, and the inner wall of the conical adjusting block is provided with a smooth coating. By adopting the above technical solution, the adjusting block is designed as a cone and the inner wall of the cone is coated with a smooth coating. The cone structure provides a gradual guiding effect for the shrinkage of the shrink plate, making the shrinkage adjustment more stable and precise. The smooth coating reduces the frictional resistance between the shrink plate and the adjusting block, reduces wear during the adjustment process, and makes the adjustment operation more effortless and smooth.
[0008] Preferably, a clamping block is fixedly connected to the end of the shrink plate away from the first sleeve, and an anti-wear block is fixedly connected to the side of the clamping block, and the clamping block is located inside the adjusting block; By adopting the above technical solution, the clamping block at the end of the shrink plate cooperates with the anti-wear block on the side, and the clamping block is located inside the adjusting block. The clamping block can further enhance the clamping stability of the pipe, and the anti-wear block can avoid pipe damage caused by direct friction between the clamping block and the outer wall of the pipe. At the same time, it reduces the wear of the clamping block itself, protects the pipe and improves the durability of the device.
[0009] Preferably, a baffle is fixedly connected inside the first sleeve, the sealing gasket is in contact with the baffle, and the sealing gasket is made of silicone. By adopting the above technical solution, the baffle inside the first sleeve contacts the silicone sealing gasket. The baffle provides stable support and positioning for the sealing gasket, ensuring that the sealing gasket is not easily displaced under pressure. The silicone sealing gasket has excellent elasticity and sealing performance. Under pressure, it can tightly fit the outer wall of the pipe, effectively preventing water leakage and improving sealing reliability.
[0010] Preferably, a limiting ring is fixedly connected to the outside of the water inlet pipe, and a groove adapted to the limiting ring is opened inside the adjusting ring, with the limiting ring located inside the groove of the adjusting ring; By adopting the above technical solution, the limiting ring on the outside of the water inlet pipe cooperates with the groove inside the adjusting ring to play an axial limiting role for the adjusting ring, preventing axial displacement or detachment of the adjusting ring during rotation and use, ensuring the stability of the connection between the adjusting ring and the water inlet pipe, and ensuring the normal operation of the adjustment.
[0011] Preferably, the outer side of the adjusting ring is provided with a plurality of threaded holes, and a positioning bolt is threaded into the threaded holes of the adjusting ring. By adopting the above technical solution, the positioning bolts on the outside of the adjusting ring can be tightened after the adjusting ring has been adjusted. The position of the adjusting ring is locked by the tightness between the end of the bolt and the outer wall of the water inlet pipe, which prevents it from loosening due to vibration and other factors during subsequent use, thus ensuring the stability of the overall structure and maintaining the stable state of the pipeline connection.
[0012] Preferably, the outer side of the second sleeve is provided with a plurality of sliding grooves, and the inner side of the rotating ring is fixedly connected with a plurality of sliders, the plurality of sliders being located inside the plurality of sliding grooves and slidably connected to the sliding grooves; By adopting the above technical solution, the sliding groove on the outer side of the second sleeve is slidably connected to the slider on the inner side of the rotating ring, realizing the transmission connection between the adjusting ring and the second sleeve. This allows the rotational motion of the adjusting ring to be stably transmitted to the second sleeve, thereby driving the first sleeve to move axially. At the same time, the cooperation between the sliding groove and the slider restricts the relative rotation of the two, ensuring the high efficiency and stability of power transmission and guaranteeing the smooth and reliable adjustment process.
[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This multi-diameter interface water meter, through the arrangement of an inlet pipe, a first sleeve, a second sleeve, a shrink plate, a clamping block, an anti-wear block, an adjusting block, an adjusting ring, a rotating ring, a slider, a sliding groove, a sealing gasket, and a clamping nut, requires the operator to place the water pipe body inside the first sleeve so that the water pipe body contacts the adjusting block. Then, rotating the adjusting ring causes the rotating ring to drive the slider to rotate, thereby causing the second sleeve to drive the first sleeve to move axially along the thread direction inside the inlet pipe. This movement is achieved through the conical structure of the adjusting block. The shrink plate is forced to contract, causing the clamping block to hold and fix the water pipe body, thus completing the fixation of the water pipe body and the inlet pipe. At this time, the clamping nut can be inserted into the inside of the first sleeve to press the sealing gasket, causing the sealing gasket to deform and fit tightly with the water pipe body, preventing water leakage. This solves the problem of using additional fittings such as adapters, reducing flanges or reducers to connect to a single fixed diameter water meter, which not only increases material costs and inventory management difficulty, but also leads to complicated installation process, extended construction time, and the introduction of multiple potential leakage points.

Detailed Implementation
[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0017] Example 1: A water meter with multiple diameter interfaces, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a water meter body 1, a metering module 2 installed inside the water meter body 1, a water inlet pipe 3 fixedly connected to the water inlet of the water meter body 1, a first sleeve 4 threadedly connected to the inner side of the water inlet pipe 3, a second sleeve 5 fixedly connected to one end of the first sleeve 4, several shrink plates 6 fixedly connected to the end of the first sleeve 4 away from the second sleeve 5, an adjusting block 9 fixedly connected inside the water inlet pipe 3, a sealing gasket 11 inside the first sleeve 4, a threaded groove on the inner wall of the second sleeve 5 threadedly connected to a clamping nut 12, an adjusting ring 13 sleeved on the outer side of the water inlet pipe 3, a rotating ring 15 fixedly connected to one end of the adjusting ring 13, a water pipe body 19 inside the water inlet pipe 3, and shrink plates 6 made of spring steel. Made of the same material, the shrink plate 6 is evenly distributed circumferentially at one end of the first sleeve 4. The adjusting block 9 is conical in shape, and the inner wall of the conical adjusting block 9 is coated with a smooth coating. A clamping block 7 is fixedly connected to the end of the shrink plate 6 away from the first sleeve 4. An anti-wear block 8 is fixedly connected to the side of the clamping block 7. The clamping block 7 is located inside the adjusting block 9. A baffle 10 is fixedly connected inside the first sleeve 4. A sealing gasket 11 is in contact with the baffle 10. The sealing gasket 11 is made of silicone. A limiting ring 18 is fixedly connected to the outside of the water inlet pipe 3. A groove adapted to the limiting ring 18 is opened inside the adjusting ring 13. The limiting ring 18 is located in the groove inside the adjusting ring 13. Several threaded holes are opened on the outside of the adjusting ring 13. The device is internally threaded with a positioning bolt 14. Several grooves 16 are formed on the outer side of the second sleeve 5. Several sliders 17 are fixedly connected to the inner side of the rotating ring 15. These sliders 17 are located inside and slidably connected to the grooves 16. Through the arrangement of the water inlet pipe 3, first sleeve 4, second sleeve 5, shrink plate 6, clamping block 7, anti-wear block 8, adjusting block 9, adjusting ring 13, rotating ring 15, sliders 17, grooves 16, sealing gasket 11, and clamping nut 12, during use, the operator must place the water pipe body 19 inside the first sleeve 4, ensuring the water pipe body 19 contacts the adjusting block 9. Then, rotating the adjusting ring 13 causes the rotating ring 15 to drive the sliders 17 to rotate, thereby causing the second sleeve 5 to rotate. The second sleeve 5 drives the first sleeve 4 to move axially along the thread direction inside the water inlet pipe 3. This forces the shrink plate 6 to shrink through the conical structure of the adjusting block 9, so that the clamping block 7 clamps and fixes the water pipe body 19, thus completing the fixation of the water pipe body 19 and the water inlet pipe 3. At this time, the clamping nut 12 can be inserted into the interior of the first sleeve 4 to press the sealing gasket 11, so that the sealing gasket 11 deforms and fits tightly with the water pipe body 19, preventing water leakage. This solves the problem that using additional fittings such as adapters, reducing flanges or reducing pipes to connect a single fixed diameter water meter not only increases material costs and inventory management difficulty, but also leads to complicated installation process, extended construction time, and the introduction of multiple potential leakage points.
[0018] The implementation principle of this application embodiment is as follows: During use, the operator inserts the water pipe body 19 into the first sleeve 4. When inserted, the water pipe body 19 passes through the sealing gasket 11, which tightly wraps the water pipe body 19. One end of the water pipe body 19 inside the first sleeve 4 contacts the adjusting block 9. After contact, the operator rotates the adjusting ring 13, causing the adjusting ring 13 to rotate outside the limiting ring 18. After the adjusting ring 13 rotates, the rotating ring 15 drives the slider 17 to rotate. After the slider 17 rotates, it causes the second sleeve 5 to rotate through the sliding groove 16. After the second sleeve 5 rotates, it causes the first sleeve 4 to rotate. Since the first sleeve 4 is threadedly connected to the water inlet pipe 3, it moves axially inside the water inlet pipe 3 after the first sleeve 4 rotates. When the first sleeve 4 moves, the slider 17 slides inside the sliding groove 16, continuously causing the second sleeve 5 to rotate. After the first sleeve 4 moves, the anti-wear block 8 contacts the conical adjusting block 9. This causes the shrink plate 6 to begin tightening until the clamping block 7 clamps the water pipe body 19. The operator then stops rotating the adjusting ring 13. Next, the operator rotates the positioning bolt 14, causing it to thread onto the adjusting ring 13 and contact the inlet pipe 3, thus limiting the adjusting ring 13 and preventing its rotation. The operator then places the clamping nut 12 at the end of the second sleeve 5 furthest from the first sleeve 4, and rotates it. Because the clamping nut 12 is threaded onto the second sleeve 5, it moves axially into the second sleeve 5 during rotation and enters the first sleeve 4 through it until the clamping nut 12 contacts the sealing gasket 11 at one end of the first sleeve 5 and compresses it. The compressed sealing gasket 11 deforms, sealing the inlet pipe 3. The device is then tested to see if it functions properly.
