[0002] A household water meter system integration package is installed in the water meter box before the tap water enters the household, which controls the water circuit. Traditional household water meter system integration packages require wrapping Teflon tape to connect adjacent valves, which is troublesome to install and maintain, requires skilled installers, takes a long time, and has high installation costs. Moreover, because a threaded connector is required between the two connected valves, the overall length of the household water meter system integration package is too long, making it inconvenient to install in the water meter box, and the large flow resistance causes additional water flow loss. Utility Model Content

[0003] The purpose of this utility model is to propose a household meter system integration package, which solves the technical problems of existing household meter system integration packages, such as troublesome installation and maintenance, long installation time, high skill requirements for installers, and excessive overall length of the household meter system integration package due to the installation of threaded connectors.

[0056] A household water meter system integration package is installed in the water meter box before the tap water enters the household, which controls the water circuit. Traditional household water meter system integration packages require wrapping Teflon tape to connect adjacent valves, which is troublesome to install and maintain, requires skilled installers, takes a long time, and has high installation costs. Moreover, because a threaded connector is required between the two connected valves, the overall length of the household water meter system integration package is too long, making it inconvenient to install in the water meter box, and the large flow resistance causes additional water flow loss.

[0057] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment provides a household meter system integration package, including a water meter component 1, a first shut-off valve 2, a check valve 3, and a second shut-off valve 4. The first shut-off valve 2 is installed at the front end (water inlet end) of the water meter component 1, and the water meter component 1 and the first shut-off valve 2 are sealed together by a quick-connect structure 5. The check valve 3 and the second shut-off valve 4 are installed at the rear end (water outlet end) of the water meter component 1, and the check valve 3 is located between the water meter component 1 and the second shut-off valve 4. The check valve 3 is sealed together with the water meter component 1 and the second shut-off valve 4 by a quick-connect structure 5.

[0058] In this household meter system integration package, the water meter component 1 and the first shut-off valve 2 are sealed together by a quick-connect structure 5, and the check valve 3 is sealed together with the water meter component 1 and the second shut-off valve 4 by a quick-connect structure 5. That is, both are sealed together by a quick-connect structure 5, eliminating the need for Teflon tape and threaded connectors, simplifying installation, greatly accelerating installation efficiency, and reducing the skill requirements for installers. Moreover, it shortens the overall length of the household meter system integration package, making it easier to install inside the water meter box. The shortened length also reduces flow resistance and water flow loss.

[0059] Optionally, the first shut-off valve 2 and the second shut-off valve 4 are gate valves, ball valves, or globe valves. The first shut-off valve 2 and the second shut-off valve 4 can be configured as gate valves, ball valves, or globe valves according to requirements to meet different application needs. In this embodiment, the first shut-off valve 2 is a gate valve, which has the advantages of low flow resistance design, bidirectional sealing capability, and high durability; the second shut-off valve 4 is a globe valve, which has the advantages of precise flow regulation, reliable high-pressure sealing, and convenient maintenance. In other embodiments, the first shut-off valve 2 and the second shut-off valve 4 can also be selected from other types of shut-off valves according to requirements.

[0060] Optionally, the water meter assembly 1 includes a water meter 11, a first adapter 12, and a second adapter 13. The first adapter 12 is located at the front end of the water meter 11, and the second adapter 13 is located at the rear end of the water meter 11. The water meter 11 is threadedly connected to the first adapter 12 and the second adapter 13. The first adapter 12 is sealed to the first shut-off valve 2 via a quick-connect structure 5, and the second adapter 13 is sealed to the check valve 3 via a quick-connect structure 5. In this embodiment, the water meter 11 is connected to the first adapter 12 and the second adapter 13 via a union nut, which allows for a quick and convenient connection. The quick connection between the first adapter 12 and the first shut-off valve 2, and the quick-connect structure 5, and the quick-connect structure 5 between the second adapter 13 and the check valve 3, enables a rapid connection between the two.

[0061] Furthermore, such as Figures 3-5As shown, the quick-connect structure 5 includes a first socket 51, a first plug 52, and a plug-in 53. Both the first socket 51 and the first plug 52 are tubular structures. The first socket 51 is provided with a first insertion hole 511, which is connected to the interior of the first socket 51. The first plug 52 is provided with a first slot 521. The structures of the first socket 51 and the first plug 52 are compatible. The first socket 51 can be fitted onto the first plug 52, and the two are sealed together. The first insertion hole 511 and the first slot 521 are arranged opposite to each other. The plug-in 53 can be inserted into the first insertion hole 511 and the first slot 521 to connect the first socket 51 and the first plug 52. The quick-connect structure 5 has a first sleeve 51 on one of the two interlocking structures and a first plug 52 on the other. The first sleeve 51 can be fitted onto the first plug 52, and the first socket 511 on the first sleeve 51 is opposite to the first slot 521 on the first plug 52. The plug 53 is inserted into the first socket 511 and the first slot 521 to seal the first sleeve 51 and the first plug 52. The quick-connect structure 5 is simple and the connection operation is relatively convenient.

[0062] Optionally, a first plug 52 is provided on one of the first adapter 12 of the water meter assembly 1 and the first shut-off valve 2, and a first socket 51 is provided on the other; a first plug 52 is provided on one of the second adapter 13 of the water meter assembly 1 and the check valve 3, and a first socket 51 is provided on the other; a first plug 52 and a first socket 51 are provided on one of the check valve 3 and the second shut-off valve 4.

[0063] In this embodiment, a first socket 51 is provided on the first shut-off valve 2, and a first plug 52 is provided on the first adapter 12. The first socket 51 of the first shut-off valve 2 is plugged into the first plug 52 of the first adapter 12. A first plug 52 is provided on the second adapter 13. A first socket 51 is provided at one end of the check valve 3. The first socket 51 of the check valve 3 is plugged into the first plug 52 of the second adapter 13. A first plug 52 is provided at the other end of the check valve 3. A first socket 51 is provided on the second shut-off valve 4. The first socket 51 of the second shut-off valve 4 is plugged into the first plug 52 of the check valve 3.

[0064] Furthermore, a first insertion hole 511 is provided on the circumferential sidewall of the first socket 51. The first insertion hole 511 is perpendicular to the axis of the first socket 51. In this embodiment, the circumferential sidewall of the first socket 51 protrudes outward so that the first insertion hole 511 can be perpendicular to the axis of the first socket 51. The first insertion hole 511 penetrates the sidewall of the first socket 51 and communicates with the interior of the first socket 51. A first slot 521 is provided circumferentially along the first connector 52. When the first connector 52 extends into the first socket 51, the first slot 521 can communicate with the first insertion hole 511.

[0065] Preferably, the first slot 521 is a circular structure surrounding the first connector 52, meaning that the first connector 52 has the first slot 521 around its entire circumference. The first connector 52 is inserted into the first sleeve connector 51 and can rotate relative to the first sleeve connector 51. The connector 53 can be inserted into and stop at any position in the first slot 521. This arrangement allows the first connector 52 and the first sleeve connector 51 to rotate 360 ​​degrees axially and then lock, solving the problem of valve installation orientation and making it more convenient to install the household meter system integration package in a limited space, eliminating installation interference problems.

[0066] Optionally, one end of the first socket 511 is provided with an opening, and the inner wall of the opening is provided with an internal thread. The connector 53 is inserted into the first socket 511 and is threadedly connected to the internal thread, thereby fixing the connector 53 in the first socket 511 and preventing the connector 53 from arbitrarily coming out of the first socket 511.

[0067] Optionally, a limiting step and / or an axially arranged retaining ring 522 are provided within the first socket 51. The first plug 52 is inserted into the first socket 51, with its end face abutting against the limiting step and the end face of the first socket 51 abutting against the retaining ring 522. That is, a limiting step can be provided within the first socket 51 to limit the depth of the first plug 52 extending into the first socket 51. A retaining ring 522 can also be provided circumferentially around the first plug 52. Alternatively, both a limiting step and a retaining ring 522 can be provided simultaneously. In this embodiment, a limiting step is provided within the first socket 51, and a retaining ring 522 is provided circumferentially around the first plug 52. When the first plug 52 is inserted into the first socket 51, its end face abuts against the limiting step, and simultaneously, the end face of the first socket 51 abuts against the retaining ring 522. The first plug 52 is thus properly installed, and this structure provides good sealing and waterproofing. When the first connector 52 is installed in place, the first socket 511 and the first slot 521 are aligned.

[0068] Optionally, a filter and / or a pressure reducing valve are provided between the first adapter 12 and the first shut-off valve 2, with the filter achieving the function of filtration and the pressure reducing valve achieving the function of pressure reduction.

[0069] It should be noted that when a filter is installed, it is connected to adjacent structures via quick-connect structure 5; similarly, when a pressure reducing valve is installed, it is connected to adjacent structures via quick-connect structure 5 to improve installation efficiency. Alternatively, both a filter and a pressure reducing valve can be installed simultaneously, and they are also connected via quick-connect structure 5.

[0070] A filter pressure reducing valve 7 can also be provided between the first adapter 12 and the first shut-off valve 2 (although not shown in the figure of this embodiment, it can be found in [reference]). Figure 8 The filter pressure reducing valve 7 in the system has both filtering and pressure reducing functions, simplifying the integration of the household meter system. The filter pressure reducing valve 7 is connected to the first adapter 12 and the first shut-off valve 2 via a quick-connect structure 5, enabling rapid installation of the filter pressure reducing valve 7 and improving installation efficiency.

[0071] This household meter system integration package uses a quick-connect structure to connect two valves, eliminating the need for Teflon tape and threaded connectors, which greatly speeds up the installation efficiency. Since no threaded connectors are required, the length of the entire household meter system integration package is shortened, thus reducing water flow loss.

[0072] The quick-connect structure 5 allows two valves that are plugged in to rotate 360 ​​degrees along the axis, solving the valve installation orientation problem and making it easier to install the household meter system integration package in a limited space, eliminating installation interference problems.

[0073] The household meter system integration package connects the two components through a quick-connect structure 5, which requires less skill from workers. The overall installation requires no other components, and the fixed dimensions are controlled by the product design, eliminating valve group leakage caused by installation.

[0074] Example 2:

[0075] This embodiment provides a household meter system integration package. The difference between this embodiment and Embodiment 1 lies in the structure of the water meter component 1, such as... Figure 6 and Figure 7As shown, in this embodiment, the water meter assembly 1 includes a smart water meter 10, a first flow stabilizer 14, and a second flow stabilizer 15. The first flow stabilizer 14 is located at the front end of the smart water meter 10, and the second flow stabilizer 15 is located at the rear end of the smart water meter 10. The smart water meter 10 is threadedly connected to the first flow stabilizer 14 and the second flow stabilizer 15, respectively. The first flow stabilizer 14 is sealed to the first shut-off valve 2 via a quick-connect structure 5, and the second flow stabilizer 15 is sealed to the check valve 3 via a quick-connect structure 5. The first flow stabilizer 14 and the second flow stabilizer 15 are located at the front and rear ends of the smart water meter 10 to stabilize the water flow and ensure more accurate detection by the smart water meter 10.

[0076] Furthermore, the first flow stabilizer tube 14 is typically about 10 cm long, and the second flow stabilizer tube 15 is about 5 cm long, in order to meet industry standards.

[0077] The other structures of the user meter system integration package in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0078] Example 3:

[0079] This embodiment provides a user meter system integration package. This embodiment is an improvement on embodiment two, such as... Figure 8 As shown, in this embodiment, a shut-off check valve 6 is installed at the rear end of the smart water meter 10, and the second flow stabilizing pipe 15 is sealed to the shut-off check valve 6 through a quick-connect structure 5. The shut-off check valve 6 also functions as the check valve 3 and the second shut-off valve 4 in embodiment two. The shut-off check valve 6 has a simple structure, which simplifies the structure of the household meter system integration package.

[0080] Furthermore, a filter and / or a pressure reducing valve are provided between the first flow stabilizing pipe 14 and the first shut-off valve 2. The filter achieves the function of filtration, and the pressure reducing valve achieves the function of pressure reduction.

[0081] It should be noted that when a filter is installed, it is connected to adjacent structures via quick-connect structure 5; similarly, when a pressure reducing valve is installed, it is connected to adjacent structures via quick-connect structure 5 to improve installation efficiency. Alternatively, both a filter and a pressure reducing valve can be installed simultaneously, and they are also connected via quick-connect structure 5.

[0082] In this embodiment, as Figure 8 As shown, a filter pressure reducing valve 7 is installed between the first flow stabilizing pipe 14 and the first shut-off valve 2. The filter pressure reducing valve 7 has both filtering and pressure reducing functions, simplifying the integration package of the household meter system. The filter pressure reducing valve 7 is connected to the first flow stabilizing pipe 14 and the first shut-off valve 2 through a quick-connect structure 5, which enables the filter pressure reducing valve 7 to be installed quickly and improves installation efficiency.

[0083] The other structures of the household meter system integration package in this embodiment are the same as those in Embodiment 2, and will not be described again here.
