Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a volumetric water meter. Background Technology

[0002] A volumetric water meter measures water consumption by counting the number of times an internal fixed volume chamber is filled and emptied. The amount of water consumed is directly proportional to the number of times the chamber is filled and emptied. It has high measurement accuracy and is often used in applications requiring high-precision measurement, such as industrial fluid monitoring and scientific research experiments.

[0003] Currently, commercially available volumetric water meters, such as the device for improving the metering quality disclosed in patent CN202853671U, typically include a meter casing and a piston mechanism. A central partition is located at the bottom of the casing's inner cavity, dividing the bottom into an inlet and outlet area. Simultaneously, a support structure of the same height as the central partition is provided on the inner wall of the casing, providing a platform for installing the piston mechanism. Therefore, directly incorporating the central partition and support structure within the casing effectively forms a diversion box, isolating the inlet and outlet and supporting the piston mechanism and other components. While this structure meets the diversion and support requirements of volumetric water meters, the diversion box and casing are an integral structure, cast using a mold. Due to users' high demands for water quality and product structural strength, the casing is usually made of copper, and the integration of the diversion box into the casing results in higher overall production costs. In addition, it leads to a more complex internal structure of the watch case, which makes the mold structure more complex during the overall casting process, and the demolding process more complicated. This is not conducive to the rapid manufacturing of the watch case, resulting in low manufacturing efficiency and difficulty in meeting the needs of large-scale production. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this paper aims to provide a volumetric water meter with a separate diversion box housed within the inner cavity of the meter casing. The diversion box is made of plastic, enabling separate arrangement and subsequent assembly of the diversion box and the meter casing. Furthermore, the diversion box is made of a lower-cost material, reducing manufacturing costs. Additionally, the separation of the diversion box and the meter casing simplifies the structure of each component, facilitating individual manufacturing followed by reassembly. This results in simpler molds and manufacturing processes, higher manufacturing efficiency, and meets the needs of large-scale production.

[0005] The specific technical solution is as follows:

[0006] A volumetric water meter includes a casing and a metering component, the metering component being installed inside the casing. It also includes a flow divider box. The casing has a mounting cavity arranged from top to bottom. An external inlet and an external outlet, both communicating with the mounting cavity, are respectively opened on both sides of the bottom of the casing. The mounting cavity has an upper opening, and the cross-section of the mounting cavity located in the middle or upper part of the casing is greater than or equal to the cross-section of the bottom. The flow divider box is detachably installed and mounted inside the bottom of the mounting cavity. The metering component is installed within the mounting cavity. In the middle and upper part of the cavity, the diversion box is arranged in a barrel shape with the barrel opening facing upwards. The diversion box is equipped with a vertically arranged partition to divide the inner cavity of the diversion box into an inlet chamber and an outlet chamber. The two sides of the diversion box are respectively provided with an inner inlet and an inner outlet that communicate with the inlet chamber and the outlet chamber. After the diversion box is installed in the installation cavity, the inner inlet and the inner outlet communicate with the outer inlet and the outer outlet, respectively. The barrel opening of the diversion box abuts against the bottom of the metering component. The diversion box is made of plastic.

[0007] In the aforementioned volumetric water meter, a positioning hole is provided on the meter casing and inside the bottom of the mounting cavity, and a positioning block that mates with the positioning hole is provided on the outer side of the bottom of the diversion box.

[0008] In the aforementioned volumetric water meter, a sealing groove is formed on the side wall of the diversion box, outside the inner inlet and the inner outlet. A sealing ring is provided in each sealing groove, and when the diversion box is installed in the mounting cavity of the meter housing, the two sealing rings abut against the inner side wall of the mounting cavity.

[0009] In the aforementioned volumetric water meter, a groove is formed at the bottom of the metering component, and a sealing ring is provided in the groove, with the sealing ring abutting against the opening of the diversion box.

[0010] The aforementioned volumetric water meter further includes a stabilizing adjustment component, which is disposed between the diversion box and the meter housing. The stabilizing adjustment component is distributed on the outer side of the diversion box and abuts against the inner wall of the mounting cavity.

[0011] In the aforementioned volumetric water meter, each stabilizing adjustment component includes an inclined insert block. Several guide grooves are formed on the outer wall of the diversion box along the vertical direction. Each guide groove corresponds to a stabilizing adjustment component. The inclined insert block is slidably disposed in the corresponding guide groove, and the groove wall of the guide groove is arranged at an inclination in the vertical direction.

[0012] In the aforementioned volumetric water meter, each stabilizing adjustment component further includes a clamping component, and each inclined block has a corresponding clamping component. The clamping component is arranged vertically with one end abutting against the corresponding inclined block and the other end abutting against the bottom of the metering component.

[0013] In the aforementioned volumetric water meter, the guide channels are all located at the connection point between the inner wall of the distribution box and the partition.

[0014] In the aforementioned volumetric water meter, the guide groove is located on the outside of the sealing ring in the radial direction of the diversion box.

[0015] The positive effects of the above technical solution are:

[0016] The aforementioned volumetric water meter achieves separate arrangement and combined installation of the meter casing and the diversion box by disassembling and installing a plastic diversion box inside the mounting cavity at the bottom of the casing. This allows the diversion box to be made of lower-cost plastic, reducing the overall cost of the water meter. In addition, the separate arrangement of the meter casing and the diversion box simplifies their respective structures, making mold making simpler, eliminating the need for more complex processing techniques, increasing manufacturing efficiency, facilitating processing and manufacturing, and meeting the needs of large-scale production.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0022] Figure 1 This is a structural diagram of an embodiment of the present invention: a volumetric water meter. Figure 2 This is a schematic diagram illustrating the installation of the watch case and the distributor box according to a preferred embodiment of this utility model. Figure 1 and Figure 2As shown, the volumetric water meter provided in this embodiment includes: a casing 1, a metering component 2, and a diversion box 3 disposed inside the casing 1 and abutting against the metering component 2. Water flows into the casing 1 and then through the diversion box 3 into the metering component 2. After being counted by the metering component 2, the water is discharged out of the casing 1 through the diversion box 3, thus meeting the usage requirements for water consumption monitoring. It is worth noting that the metering component 2 is a commonly used metering component 2 in commercially available volumetric water meters. A suitable type of metering component 2 can be selected and assembled into the casing 1. Therefore, the specific structure and working principle of the metering component 2 will not be described in detail here.

[0023] Specifically, the casing 1 has a mounting cavity 11 arranged from top to bottom, providing space for the subsequent installation of the flow divider box 3 and the metering component 2. Meanwhile, an external water inlet 12 and an external water outlet 13 are respectively opened on both sides of the bottom of the casing 1, and both the external water inlet 12 and the external water outlet 13 are connected to the mounting cavity 11. This allows water entering from the external water inlet 12 to first enter the mounting cavity 11, be metered, and then discharged through the external water outlet 13, meeting usage requirements. Furthermore, the mounting cavity 11 has an upper opening, allowing the flow divider box 3 and the metering component 2 to be installed into the mounting cavity 11 through the upper opening, facilitating assembly. Furthermore, the cross-section of the mounting cavity 11 located in the middle or upper part of the housing 1 is set to be greater than or equal to the cross-section of the bottom. This ensures that when the diversion box 3 and the metering component 2 are installed from the upper opening of the mounting cavity 11 into the mounting cavity 11, they will not be blocked by the structure on the inner wall of the mounting cavity 11, ensuring that the diversion box 3 can be smoothly installed to the bottom of the mounting cavity 11. Moreover, the diversion box 3 is disassembled and installed in the bottom of the mounting cavity 11, filling the bottom space of the mounting cavity 11. Additionally, the metering component 2 is installed in the middle and upper parts of the mounting cavity 11, so that water entering the mounting cavity 11 from the bottom of the housing 1 first enters the diversion box 3 for diversion. The diverted water then enters the metering component 2 for counting, and the counted water is discharged back into the diversion box 3. Finally, the water is discharged from the bottom of the housing 1 through the diversion box 3, meeting the water consumption monitoring requirements. Furthermore, the diversion box 3 is arranged in a barrel shape with its opening facing upwards, forming a stable internal cavity to ensure a stable flow rate during subsequent metering. The diversion box 3 and the metering component 2 can be connected through their openings, meeting the requirements for water flow between them. Additionally, a vertically arranged partition 31 is installed inside the diversion box 3, dividing its internal cavity into an inlet chamber 32 and an outlet chamber 33, thus isolating the inlet and outlet water. In addition, an inner inlet 34 and an inner outlet 35 are respectively provided on both sides of the diversion box 3, and the inner inlet 34 and the inner outlet 35 are connected to the inlet chamber 32 and the outlet chamber 33 respectively. After the diversion box 3 is installed in the installation cavity 11 and in place, the inner inlet 34 and the inner outlet 35 are connected to the outer inlet 12 and the outer outlet 13 respectively. The opening of the diversion box 3 is then placed against the bottom of the metering component 2, so that the water flowing in from the outer inlet 12 will enter the inlet chamber 32 of the diversion box 3 through the inner inlet 34. The water in the inlet chamber 32 will then enter the metering component 2. After the water has been metered by the metering component 2, it will return to the outlet chamber 33 of the diversion box 3 and finally be discharged through the inner outlet 35 and the outer outlet 13, thus realizing volumetric water consumption metering.In addition, the diversion box 3 is made of plastic, while the meter housing 1 is still made of copper. Compared with the one-piece meter housing 1, the use of copper is reduced, and the diversion box 3 is made of lower-cost plastic. This not only meets the usage requirements, but also effectively reduces the manufacturing cost. In addition, it also realizes the separate arrangement of the diversion box 3 and the meter housing 1, so that the diversion box 3 and the meter housing 1 can be processed separately. This makes the structure of the diversion box 3 and the meter housing 1 simpler, which in turn makes the structure of the corresponding mold simpler. It does not require more complicated processing technology, improves manufacturing efficiency, facilitates processing and manufacturing, and better meets the needs of large-scale production of volumetric water meters.

[0024] More specifically, a positioning hole 14 is provided on the casing 1 and on the inner side of the bottom of the mounting cavity 11. One or more positioning holes 14 are provided. At the same time, a positioning block 36 that cooperates with the positioning hole 14 is provided on the outer side of the bottom of the diverter box 3. This allows the diverter box 3 to be installed in the mounting cavity 11 by the positioning block 36 being inserted into the corresponding positioning hole 14 to achieve assembly positioning and post-installation limitation, meeting the needs of rapid assembly and ensuring that the inner inlet 34 and inner outlet 35 of the diverter box 3 can always be connected to the outer inlet 12 and outer outlet 13 respectively, preventing the diverter box 3 from moving in the mounting cavity 11 during use and affecting the flow rate.

[0025] More specifically, a sealing groove 37 is formed on the side wall of the diversion box 3, outside the inner inlet 34 and the inner outlet 35. At the same time, a sealing ring is provided in each sealing groove 37. When the diversion box 3 is installed in the mounting cavity 11 of the casing 1, the two sealing rings can abut against the inner side wall of the mounting cavity 11 respectively, so as to seal the gaps between the diversion box 3 and the casing 1, the outer inlet 12, the inner inlet 34, the inner outlet 35 and the outer outlet 13, thereby improving the sealing performance.

[0026] More specifically, a groove 21 is provided at the bottom of the metering component 2, and a sealing ring is provided in the groove 21. When the metering component 2 is installed in the meter case 1, the sealing ring can abut against the opening of the diverter box 3 to achieve a seal between the bottom of the metering component 2 and the opening of the diverter box 3, thus preventing water leakage.

[0027] Figure 3 This is a structural diagram of a stabilizing adjustment component according to a preferred embodiment of the present invention. Figure 1 and Figure 3As shown, a stabilizing adjustment component 4 is also provided between the shunt box 3 and the meter housing 1. At this time, the stabilizing adjustment component 4 is distributed on the outside of the shunt box 3 and abuts against the inner wall of the mounting cavity 11. Since the shunt box 3 is installed in the meter housing 1 by a combination assembly method, there is an assembly gap, which may cause the shunt box 3 to shift during use, thereby affecting the measurement accuracy. However, the stabilizing adjustment component 4 can fill the gap between the shunt box 3 and the meter housing 1, eliminating the risk of movement of the shunt box 3 after installation and improving the installation stability of the shunt box 3.

[0028] More specifically, each stabilizing adjustment component 4 located between the diverter box 3 and the watch case 1 includes an inclined insert block 41. At this time, several guide grooves 38 are provided on the outer side wall of the diverter box 3 in the vertical direction. The guide grooves 38 extend along the barrel opening side of the diverter box 3 towards the bottom. Each guide groove 38 corresponds to a stabilizing adjustment component 4, which facilitates the installation of the stabilizing adjustment component 4 from the upper opening of the watch case 1, making the operation more convenient. In addition, the inclined insertion block 41 is slidably disposed in the corresponding guide groove 38, and the groove wall of the guide groove 38 is arranged obliquely in the vertical direction, so that the groove depth of the guide groove 38 is deeper closer to the barrel opening of the diverter box 3, and shallower closer to the bottom of the diverter box 3. When the inclined insertion block 41 is inserted into the corresponding guide groove 38 from one end of the barrel opening of the diverter box 3 and the inclined insertion block 41 is pressed downward, the two sides of the inclined insertion block 41 will respectively press the outer side wall of the diverter box 3 and the inner side wall of the mounting cavity 11, thereby squeezing into the assembly gap between the casing 1 of the diverter box 3, restricting the movement of the diverter box 3, and ensuring that the diverter box 3 is more stable after installation.

[0029] More specifically, each stabilizing adjustment component 4 includes not only the aforementioned inclined insertion block 41, but also a clamping component 42. During assembly, each inclined insertion block 41 corresponds to a clamping component 42. The clamping component 42 is arranged vertically with one end abutting against the corresponding inclined insertion block 41, so that the arrangement direction of the clamping component 42 is the arrangement direction of the guide groove 38. At the same time, the other end of the clamping component 42 abuts against the bottom of the metering component 2, so that when the metering component 2 is installed in the case 1, the bottom of the metering component 2 can press down on the inclined insertion block 41 through the clamping component 42, preventing the inclined insertion block 41 from coming out in the opposite direction and causing the diverter box 3 to loosen, thus further ensuring the stability of the diverter box 3 after installation.

[0030] More specifically, the guide grooves 38 on the diversion box 3 are all set at the part where the inner wall of the diversion box 3 connects with the partition 31. Since both ends of the partition 31 need to be connected to the side wall of the inner cavity of the diversion box 3, the wall thickness at the junction of the two is thicker and the structural strength is higher. Opening the guide grooves 38 at this place will not have too much impact on the diversion box 3 itself, and the structural design is more reasonable.

[0031] More specifically, in the radial direction of the diversion box 3, the guide groove 38 is set on the outside of the sealing ring, so that the guide groove 38 is located on the outside of the sealing ring. This ensures that when the diversion box 3 and the metering component 2 are assembled together, the inclined insert 41 and the clamping member 42 in the guide groove 38 will not interfere with the sealing of the sealing ring when the diversion box 3 and the metering component 2 are sealed through the sealing ring. This ensures the stability of the structure after installation while guaranteeing the sealing.

[0032] The volumetric water meter provided in this embodiment includes a casing 1, a diversion box 3, and a metering component 2. By disassembling and installing the diversion box 3 within the mounting cavity 11 of the casing 1, and installing the metering component 2 within the mounting cavity 11 and abutting against the diversion box 3, the casing 1 and the diversion box 3 are designed separately and then combined for installation while meeting the volumetric water consumption requirements. This allows the diversion box 3 and the casing 1 to be made of different materials, replacing the original copper diversion box 3 with a lower-cost plastic material, thus reducing the manufacturing cost of the water meter. In addition, the separate casing 1 and the diversion box 3 simplify their respective structures, making the corresponding manufacturing mold structure simpler, simplifying the processing technology, improving manufacturing efficiency, and facilitating manufacturing, thus better meeting the needs of large-scale production of volumetric water meters.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
