Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, and in particular relates to an electromagnetic water meter connection structure. Background Art

[0002] In order to enhance water leakage control and reduce water waste, municipal administration in large cities has begun to establish DMA leakage control management systems. In terms of hardware, it is necessary to add electromagnetic water meters to each water supply node. Due to the narrow space in the valve well, conventional electromagnetic water meters on the market are of standard length. The electromagnetic water meter with a nominal diameter of 100mm is 250mm long (DN100: 250mm), the electromagnetic water meter with a nominal diameter of 150mm is 300mm long (DN150: 300mm), and the electromagnetic water meter with a nominal diameter of 200mm is 350mm long (DN200: 350mm). All of them are relatively long and cannot be installed directly on one side of the valve when used with other connecting equipment.

[0003] There are two main solutions. One is to set up a separate electromagnetic water meter well, digging a separate well next to the valve well to install the electromagnetic water meter. The other is to remove the branch pipe valve, cut the branch pipe length, and then reinstall the valve and water meter together.

[0004] The problems with both of the aforementioned solutions are that they require extensive engineering work and require a water outage in the main pipeline, which would impact a wide area and prevent many residents from accessing water. Furthermore, the first method requires damaging the road surface, making it unsuitable for areas with valuable conservation value or narrow areas (such as alleyways in large cities, old villages, and ancient towns). The second method sometimes also requires widening the valve well for construction. Utility Model Content

[0005] In view of this, the utility model provides an electromagnetic water meter connection structure with a simple structure, short length, no need to stop water supply, can be directly installed next to the valve in the valve well, and can be quickly connected, thereby improving installation efficiency.

[0006] The utility model is realized through the following technical solutions:

[0007] An electromagnetic water meter connection structure, comprising: an electromagnetic water meter and a pipe connector;

[0008] The electromagnetic water meter includes a water meter body, a meter seat and a connecting pipe;

[0009] One end of the connecting pipe is coaxially fixedly connected to one end of the pipe connector; the other end of the pipe connector is used to coaxially fixedly connect to the pipe;

[0010] The meter base is fixed on the connecting pipe, and the water meter body is fixed on the meter base;

[0011] The orthographic projection area of ​​the meter seat on the connecting pipe is smaller than the orthographic projection area of ​​the water meter body on the connecting pipe.

[0012] Furthermore, the meter base is a stepped cylindrical structure, including a large cylindrical section and a small cylindrical section; the end of the small cylindrical section is connected to the connecting pipe, and the end face of the small cylindrical section is an arc surface for cooperating with the connecting pipe; the water meter body is arranged on the end face of the large cylindrical section.

[0013] Furthermore, the meter base and the connecting pipe are integrally formed.

[0014] Furthermore, the peripheral components include: valve wells, main water supply pipes, branch water supply pipes and valves;

[0015] The water supply branch pipe passes through two opposite side walls of the valve well in sequence and is connected to the water supply main pipe. The valve is installed on the water supply branch pipe and is located in the valve well. The part of the water supply branch pipe located downstream of the valve is called branch pipe section II.

[0016] The electromagnetic water meter connection structure is arranged in the valve well and connected between the branch pipe section II and the valve.

[0017] Furthermore, flanges are provided at both ends of the connecting pipe, a flange is provided at the downstream end of the valve, and a flange is provided at the upstream end of the pipe connector;

[0018] The upstream end of the connecting pipe is fixedly connected to the valve through a flange, and the downstream end of the connecting pipe is fixedly connected to the pipeline connector through a flange.

[0019] Furthermore, when the nominal diameter of the water supply branch pipe is 100 mm, the total axial length of the electromagnetic water meter connection structure shall not exceed 400 mm; the actual pipe length occupied by the electromagnetic water meter connection structure shall not exceed 200 mm;

[0020] When the nominal diameter of the water supply branch pipe is 150mm, the total axial length of the electromagnetic water meter connection structure shall not exceed 420mm; the actual pipe length occupied by the electromagnetic water meter connection structure shall not exceed 220mm;

[0021] When the nominal diameter of the water supply branch pipe is 200mm, the total axial length of the electromagnetic water meter connection structure shall not exceed 450mm; the actual pipe length occupied by the electromagnetic water meter connection structure shall not exceed 250mm.

[0022] Furthermore, when the nominal diameter of the water supply branch pipe is 65 mm, 80 mm, 250 mm, 300 mm and 400 mm, the length of the electromagnetic water meter is shortened to less than 60% of the original standard length.

[0023] Beneficial effects:

[0024] (1) The water meter connection structure provided by the present invention has a water meter body fixedly mounted on a connecting pipe via a meter base. Since the orthographic projection area of ​​the meter base on the connecting pipe is smaller than the orthographic projection area of ​​the water meter body on the connecting pipe, the axial length of the connecting pipe can be shortened to the greatest extent possible while ensuring the performance of the electromagnetic water meter, thereby adapting to installation in a narrow space. In addition, the water meter connection structure uses a pipe connector, which facilitates construction and can further improve the installation efficiency of the electromagnetic water meter connection structure.

[0025] (2) The cross-sectional area of ​​the small cylindrical section of the meter base of the utility model is small, which is conducive to shortening the length of the connecting pipe; the cross-sectional area of ​​the large cylindrical section is large, which facilitates the connection between the water meter body and the meter base.

[0026] (3) The electromagnetic water meter connection structure of the utility model is set downstream of the valve. During installation, it is only necessary to close the valve. The installation can be completed in only 1 to 2 hours without the need for large-scale water outage construction.

[0027] (4) The pipe actually occupied by the electromagnetic water meter connection structure of the present invention is shorter than the standard length of the existing electromagnetic water meter, and can be actually applied to installation in narrow spaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0033] This embodiment provides an electromagnetic water meter connection structure, see the attached Figure 1-3 , including an electromagnetic water meter 5 and a pipe connector 8;

[0034] The peripheral components include: valve well 3, water supply main pipe 1, water supply branch pipe 2 and valve 4;

[0035] The water supply branch pipe 2 passes through two opposite side walls of the valve well in sequence and is connected to the water supply main pipe 1. A valve 4 is installed on the water supply branch pipe 2 and is located in the valve well 3. The part of the water supply branch pipe 2 located upstream of the valve 4 (i.e., between the valve 4 and the water supply main pipe) is called branch pipe section I 21, and the part of the water supply branch pipe 2 located downstream of the valve 4 is called branch pipe section II 22. The electromagnetic water meter connection structure is installed in the valve well and is connected between the branch pipe section II 22 and the valve 4.

[0036] The electromagnetic water meter includes a water meter body 51, a meter base 52 and a connecting pipe 53;

[0037] One end of the connecting pipe 53 is coaxially fixedly connected to the valve 4, and the other end is coaxially fixedly connected to one end of the pipe connector 8; the other end of the pipe connector 8 is coaxially fixedly connected to the branch pipe section II 22;

[0038] The meter base 52 is fixed on the connecting pipe 53, and the water meter body 51 is fixed on the meter base 52;

[0039] The orthographic projection area of ​​the meter base 52 on the connecting pipe 53 is smaller than the orthographic projection area of ​​the water meter body 51 on the connecting pipe 53 .

[0040] It should be noted that the pipe connector 8 is a shelf product and existing technology. The pipe connector 8 can be a pipe universal connector or other general retractors, which will not be described here.

[0041] This embodiment provides an electromagnetic water meter connection structure. First, the electromagnetic water meter connection structure is installed downstream of the valve 4. Installation only requires closing the valve 4, and installation can be completed in just one to two hours, eliminating the need for large-scale water outages. Second, the water meter body 51 is fixed to the connecting pipe 53 via a meter base 52. Because the orthographic projection area of ​​the meter base 52 on the connecting pipe 53 is smaller than the orthographic projection area of ​​the water meter body 51 on the connecting pipe 53, the axial length of the connecting pipe 53 can be minimized while maintaining the performance of the electromagnetic water meter, allowing it to fit into the confined space within the valve well. Finally, the water meter connection structure uses a pipe connector 8, which further improves the installation efficiency of the electromagnetic water meter connection structure.

[0042] The meter base 52 is a stepped cylindrical structure, consisting of a large cylindrical section and a small cylindrical section. The end of the small cylindrical section is connected to the connecting tube 53, and the end surface of the small cylindrical section is a curved surface for mating with the connecting tube 53. The water meter body is mounted on the end surface of the large cylindrical section. The small cylindrical section has a small cross-sectional area, which helps shorten the length of the connecting tube 53. The large cylindrical section has a large cross-sectional area, which facilitates the connection between the water meter body and the meter base 52. In one embodiment, the meter base 52 and the connecting tube 53 are integrally formed.

[0043] In one embodiment, flanges are provided at both ends of the connecting pipe 53, a flange is provided at the downstream end of the valve 3, and a flange is provided at the upstream end of the pipe connector 8;

[0044] The upstream end of the connecting pipe 53 is fixedly connected to the valve 3 via a flange, and the downstream end of the connecting pipe 53 is fixedly connected to the pipeline connector 8 via a flange.

[0045] Specifically, when the nominal diameter of the water supply branch pipe 2 is 100 mm, the total axial length of the electromagnetic water meter connection structure is no more than 400 mm; since the pipe connector 8 and the branch pipe section II 22 are coaxially nested, the actual pipe length occupied by the electromagnetic water meter connection structure is no more than 200 mm;

[0046] When the nominal diameter of the water supply branch pipe 2 is 150 mm, the total axial length of the electromagnetic water meter connection structure is not greater than 420 mm; the actual pipe length occupied by the electromagnetic water meter connection structure is not greater than 220 mm;

[0047] When the nominal diameter of the water supply branch pipe 2 is 200 mm, the total axial length of the electromagnetic water meter connection structure is no more than 450 mm; the actual pipe length occupied by the electromagnetic water meter connection structure is no more than 250 mm.

[0048] For other calibers (such as DN65, 80, 250, 300, 400, etc.), the length of the electromagnetic water meter is shortened to less than 60% of the original standard length.

[0049] The actual pipe length occupied by the electromagnetic water meter connection structure is shorter than the standard length of existing electromagnetic water meters, making it suitable for installation in narrow spaces.

[0050] Installation method:

[0051] Step 1: Close valve 4;

[0052] Step 2: Measure and determine the cutting size of the branch pipe section II 22, and cut the branch pipe section II 22;

[0053] Step 3: Connect the downstream end of the pipe connector 8 to the cut branch pipe section II 22;

[0054] Step 4: Connect the two ends of the electromagnetic water meter to the valve 3 and the upstream end of the pipe connector 8 respectively.

[0055] Step 5: Open the valve.

[0056] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
