Description

Technical Field

[0001] This utility model relates to the field of home heating technology, and in particular to a water supply valve. Background Technology

[0002] In the field of home heating technology, wall-hung boiler heating systems are gradually gaining popularity among consumers due to their high heating efficiency and relatively low heating costs. While meeting the heating needs of households, wall-hung boiler heating systems also integrate the function of providing domestic hot water.

[0003] In a wall-mounted boiler, the heating circulation system and the hot water system are two independent flow paths, providing heating and domestic hot water to users respectively. However, as usage time increases, water will be lost from the heating circulation loop, requiring water to be replenished. The water replenishment valve typically cannot achieve effective heat exchange between the heating and hot water systems, resulting in low thermal efficiency. Furthermore, the water replenishment operation is complex, the system integration is poor, and its function is limited, making it difficult to meet the demands of modern households and industries for high efficiency, energy saving, and convenience.

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] like Figures 1 to 15As shown, a water supply valve includes: a base 1, which is provided with a first water channel 11, a second water channel 12, a third water channel 13, and a fourth water channel 14. The first water channel 11 and the third water channel 13 are connected through a first water exchange area 15, and the second water channel 12 is connected through a second water exchange area 16; a first valve 2, which is connected to the base 1. The first valve 2 is provided with a first water passage 21 that can communicate with the first water channel 11, and a second water passage 22 that is interconnected with the first water passage 21. The first valve 2 is connected to a... A first valve core assembly 3 capable of opening or closing the connection between the second water passage 22 and the first water passage 21; a second valve 4, which is connected to the base 1, wherein the second valve 4 is provided with a third water passage 41 that can communicate with the third water passage 13 and a fourth water passage 42 that can communicate with the fourth water passage 14, the second valve 4 is also provided with a fifth water passage 43 that can communicate with the third water passage 41, the second valve 4 is also provided with a second valve core assembly 5 capable of opening or closing the connection between the fifth water passage 43 and the third water passage 41, and the second valve 4 is provided with a first water outlet 4a that communicates with the fifth water passage 43.

[0038] This utility model has two water channels: a heating system and a hot water system. The heating system includes a first water inlet 4a, a fifth water passage 43, a third water passage 41, a third water channel 13, a first water exchange area 15, a first water channel 11, and a first water passage 21. The hot water system includes a fourth water passage 42, a fourth water channel 14, a second water exchange area 16, a second water channel 12, and a second water channel 22. When only heating is used, the heating water flows through the first water inlet 4a, the fifth water passage 43, and the third water passage 41, and then flows out from the side of the third water passage 41 closest to the fifth water passage 43. When heating and hot water are used simultaneously, the second valve core assembly 5 is activated, and the heating water flows through the first water inlet 4a, the fifth water passage 43, and the third water passage 41, and then sequentially through the first water inlet 4a, the fifth water passage 43, and the third water passage 41, and then through the second water channel 22. The system consists of three water channels 13, a first water exchange zone 15, a first water channel 11, and a first water path 21. At this time, the water in the hot water system flows from the second water path 22, the second water channel 12, the second water exchange zone 16, the fourth water channel 14, and the fourth water path 42, and then flows out from the outlet of the fourth water path 42. Since the first water exchange zone 15 and the second water exchange zone 16 are both located on the base 1, when the hot water in the heating system flows in the first water exchange zone 15, it can exchange heat with the water in the second water exchange zone 16 to heat the water. When water needs to be added, the first valve core assembly 3 is activated, so that the second water path 22 is connected to the first water path 21. At this time, the water in the first water path 21 can enter the second water path 22 to add water to the heating system.

[0039] It is conceivable that the first water exchange zone 15 has multiple first water exchange layers 151, and the second water exchange zone 16 includes multiple second water exchange layers 161. The multiple first water exchange layers 151 and the multiple second water exchange layers 161 are stacked vertically, and each of the second water exchange layers 161 is disposed between two adjacent first water exchange layers 151 or on the lower layer of the first water exchange layers 151. This design makes the heat exchange efficiency better.

[0040] It is conceivable that a flow meter 9 capable of monitoring the flow rate of the hot water system is also installed on the first valve 2.

[0041] The first valve 2 includes a first valve body 23 and a connecting seat 24 connected to the first valve body 23. The first valve body 23 has multiple first ports 231 that are respectively connected to the first water channel 11 and the second water channel 12. The first valve body 23 has the first water passage 21 and the second water passage 22. The connecting seat 24 can connect the first water passage 21 and the second water passage 22. The first valve core assembly 3 is connected to the connecting seat 24. The first ports 231 are provided to facilitate installation and docking, allowing the first valve body 23 to be quickly installed and positioned on the base 1. At the same time, the connecting seat 24 and the first valve body 23 have a detachable structure for easy installation. The first through hole 232 is provided to connect the first water passage 21 and the second water passage 22.

[0042] The connecting seat 24 is provided with a first channel 241 and a second channel 242 spaced apart. The connecting seat 24 is also provided with a first connecting port 243 that allows the tops of the first channel 241 and the second channel 242 to communicate. The first valve body 23 is provided with a first connecting hole 244 that allows the second channel 242 to communicate with the second water passage 22. The first valve body 23 is also provided with a third channel 245 that allows the first channel 241 to communicate with the first water passage 21. The first valve core assembly 3 can open or close the first connecting port 243 so that the first channel 241 and the second channel 242 are in a conducting state or a closed state.

[0043] When water needs to be added, the first valve core assembly 3 is activated, so that the first connection port 243 is in the open state. At this time, the first channel 241 and the second channel 242 are in the conductive state. The water flow in the second water circuit 22 of the hot water system can enter the second channel 242 from the first connecting hole 244, and then enter the first water circuit 21 after passing through the first connection port 243, the first channel 241 and the third channel 245, for adding water to the heating system.

[0044] The first valve core assembly 3 includes a first mounting base 31 connected to the connecting seat 24. The first mounting base 31 is connected to a first movable member 32 that can move relative to it, approaching or moving away from the first connection port 243. The first movable member 32 is provided with a first sealing member 33 that can move relative to it, approaching or moving away from the first connection port 243. When the first sealing member 33 approaches and fits against the first connection port 243, it can close the first connection port 243. When water needs to be added, the first movable member 32 is adjusted, and the first movable member 32 can move relative to the first mounting base 31. At this time, the first sealing member 33 connected to the first movable member 32 gradually separates from the first connection port 243, and the first connection port 243 is in an open state, connecting the first channel 241 and the second channel 242. When water does not need to be added, the first movable member 32 is rotated in the opposite direction. At this time, the first movable member 32 drives the first sealing member 33 to gradually approach the first connection port 243 and close the first connection port 243 again. The position of the first movable part 32 is observed to determine whether the first connection port 243 is open or closed.

[0045] The connecting seat 24 is provided with a protruding ring 246, and the first connecting port 243 is located at the protruding ring 246. The first sealing member 33 is located between the first channel 241 and the second channel 242 and corresponds to the protruding ring 246. When the first movable member 32 moves relative to the first mounting seat 31, the first sealing member 33 can gradually approach and contact the protruding ring 246 to close the first connecting port 243. The protruding ring 246 facilitates the setting of the first connecting port 243 and also facilitates the first sealing member 33 to abut against it, thereby completely closing the first connecting port 243 and improving the sealing performance.

[0046] A sealing element 34 is provided between the connecting seat 24 and the first mounting seat 31. The first mounting seat 31 is detachably connected to the sealing element 34, and the first mounting seat 31 has a protruding first stop portion 311. The first movable member 32 has a first stop surface 321 that can cooperate with the first stop portion 311. The first movable member 32 also has a protruding limiting portion 322. The first mounting seat 31 has a second stop surface 312 that the limiting portion 322 can abut against. The sealing element 34 cooperates with the first mounting seat 31 for waterproofing. The limiting portion 322 on the first movable member 32 can cooperate with the second stop surface 311 to abut against it, thereby limiting the range of movement of the first movable member 32. At the same time, when the first movable member 32 continues to move, the limiting portion 322 can pass through the second stop surface 312. At this time, the first stop portion 311 cooperates with the first stop surface 321, thereby preventing the first movable member 32 from detaching from the first mounting seat 31.

[0047] The second valve 4 includes a second valve body 44. The third water passage 41, the fourth water passage 42, and the fifth water passage 43 are disposed within the second valve body 44. The second valve body 44 has a second port 441 connected to the third water passage 41 and a third port 452 connected to the fourth water passage 42. The second valve 4 also has a first opening 45 and a second opening 46, which are arranged along the third water passage 41, and the fifth water passage 43 is disposed between the first opening 45 and the second opening 46. The first opening 45 and the second opening 46 can be opened or closed by the second valve core assembly 5, thus adapting to heating-only mode or simultaneous use of hot water and heating, making it very convenient to use.

[0048] The second valve core assembly 5 includes a second mounting base 51 connected to the second valve body 44. A sliding rod 52 is provided between the second mounting base 51 and the second valve body 44, which can slide relative to each other. The sliding rod 52 is provided with a second sealing member 53 and a third sealing member 54. The second sealing member 53 is located on one side of the first opening 45, and the third sealing member 54 is located on one side of the second opening 46. The second mounting base 51 is also connected to a driving member 55 that can drive the sliding rod 52 to slide. The second sealing member 53 can slide with the sliding rod 52 to close the first opening 45 or leave the first opening 45. The third sealing member 54 can slide with the sliding rod 52 to leave the second opening 46 or close the second opening 46. An elastic member 56 is provided between the third sealing member 54 and the second mounting base 51, which can push the third sealing member 54 to reset the third sealing member 54.

[0049] When switching between heating-only mode and simultaneous hot water and heating mode is required, the drive unit 55 is activated. After the drive unit 55 is activated, the sliding rod 52 is moved. At this time, the second sealing member 53 and the third sealing member 54 on the sliding rod 52 move accordingly. As the second sealing member 53 gradually closes the first opening 45, the third sealing member 54 gradually disengages from the second opening 46. At this time, the first opening 45 is closed and the second opening 46 is open. Hot water in the heating system flows out from the first water inlet 4a, the fifth water passage 43, and the third water passage 41, and then from the side of the third water passage 41 closest to the fifth water passage 43. At this time, only the heating system is working, and as the second sealing member 53 gradually disengages from the first water inlet 4a, the third water passage 43, and the fifth water passage 44, the hot water in the heating system flows out from the first water inlet 4a, the fifth water passage 43, and the third water passage 41. When the opening 45 is opened, the third sealing member 54 gradually closes the second opening 46. The heating water flows through the first water inlet 4a, the fifth water passage 43 and the third water passage 41, and then sequentially through the third water channel 13, the first water exchange area 15, the first water channel 11 and the first water passage 21. The water in the hot water system flows out from the outlet of the fourth water channel 42 after passing through the second water channel 22, the second water passage 12, the second water exchange area 16, the fourth water channel 14 and the fourth water passage 42. Since the first water exchange area 15 and the second water exchange area 16 are both located on the base 1, when the hot water in the heating system flows in the first water exchange area 15, it can exchange heat with the water in the second water exchange area 16 and heat the water.

[0050] The second valve body 44 is also provided with a sixth water passage 47, which has a first connecting channel 471 and a second connecting channel 472. One end of the first connecting channel 471 is located in front of the first opening 45, and one end of the second connecting channel 472 is located behind the second opening 46. The sixth water passage 47 can be used to connect to other water passages, making it more convenient to use.

[0051] The second valve 4 and the first valve 2 are also provided with a plurality of connectors 61 or closures 62. The second valve 4 and the first valve 2 are provided with a stop component 7 that can prevent the connectors 61 or closures 62 from detaching from the second valve 4 and the first valve 2. The stop component 7 can prevent the connectors 61 or closures 62 from detaching from the second valve 4 and the first valve 2.

[0052] The connector 61 or the sealing head 62 is provided with a top surface that can abut against the stop component 7 or a slot 63 into which the stop component 7 can be engaged. The top surface and the slot 63 ensure that the connector 61 or the sealing head 62 and the stop component 7 are in a snap-fit ​​or abutting state, making it more convenient to use. Furthermore, the second valve 4 and the first valve 2 are also provided with a stop portion 800 that prevents the stop component 7 from disengaging from the second valve 4 and the first valve 2. The stop portion 800 is designed to prevent the stop component 7 from disengaging from the second valve 4 and the first valve 2, making the stop component 7 more securely installed.

[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
