[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of the invention. However, those skilled in the art should understand that the specific components, devices, and features illustrated in the drawings and described herein are merely exemplary and should not be considered limiting.

[0025] This application aims to provide a valve device that has a filtering function and whose installation angle is not limited to one direction; it can be installed horizontally or vertically.

[0026] This application provides a valve device 1000, including a valve body component, a filter device, and a connecting member. The valve body component includes a first port portion and a second port portion. The first port portion includes a fluid inlet port, and the second port portion includes a fluid outlet port. The filter device is at least partially located between the fluid inlet port and the fluid outlet port. The valve body component includes a connecting portion, which includes a mounting port. The connecting member is detachably connected to the connecting portion. When the connecting member is detached from the connecting portion, the filter device can be disengaged from the valve body component through the mounting port. The connecting member includes a communicating channel. The connecting member includes an inner bottom wall, an inner side wall, and a partition portion extending from the inner side wall in a first direction toward the valve device. An impurity accommodating space is included between the partition portion and the inner bottom wall. The communicating channel connects the fluid inlet port and the impurity accommodating space.

[0027] The connecting component of the valve device includes a connecting channel. The connecting component includes an inner bottom wall, an inner side wall, and a baffle extending from the inner side wall in a first direction toward the valve device. There is an impurity accommodating space between the baffle and the inner bottom wall. The connecting channel connects the fluid inlet port and the impurity accommodating space, so that no impurity backflow occurs regardless of whether the valve device is installed vertically or horizontally.

[0028] For ease of description, the definition is... Figure 3 The direction indicated by the middle arrow X is the first direction, which is the vertical direction as described in this article. Figure 3 The valve assembly shown is installed vertically. Figure 4 The valve assembly 1000 shown is installed horizontally. Figure 4 As shown in the installation orientation, the horizontal direction is the first direction. Specifically, in the embodiment shown below, when the first opening of the valve core faces downwards, it is a vertical installation; when the mounting port of the valve body 1 faces downwards, it is a horizontal installation.

[0029] like Figures 1-6As shown, the valve device 1000 includes a valve body component 1, a connecting component 2, a filter device 3, and a valve core 5. The valve body component 1 includes a first port portion 110 and a second port portion 120. The first port portion 110 includes a fluid inlet port 111, and the second port portion 120 includes a fluid outlet port 121. The filter device 3 is at least partially located between the fluid inlet port 111 and the fluid outlet port 121. The valve body component 1 includes a connecting portion 13, which includes a mounting port 131. The connecting member 2 is detachably connected to the connecting portion 13. When the connecting member 2 is detached from the connecting portion 13, the filter device 3 can be disengaged from the valve body component 1 through the mounting port 131. The connecting member 2 includes a communicating channel 20. The connecting member 2 includes an inner bottom wall 210, an inner side wall 220, and a baffle portion 230 extending from the inner side wall 220 in a first direction toward the valve device 1000. The baffle portion 230 and the inner bottom wall 210 include an impurity accommodating space 200. The communicating channel 20 communicates the fluid inlet port 111 and the impurity accommodating space 200.

[0030] The valve device 1000 described above, by providing an impurity-receiving space 200 and a connecting channel 20 on the connecting member 2, allows the impurities carried by the fluid to be filtered by the filter device 3 after entering through the fluid inlet port 111 when the valve device 1000 is applied to the system. The impurities are then flushed into the impurity-receiving space 200 by the fluid through the connecting channel 20. The baffle 230 prevents impurities in the impurity-receiving space 200 from flowing back through the connecting channel 20 to the space between the filter device 3 and the fluid inlet port 111, or further back into the system pipeline where the valve device 1000 is applied. In other words, the valve device 1000 has the function of preventing the backflow of filtered impurities, thus allowing the valve device 1000 to meet the requirements for vertical installation. In contrast, the filter valves in the background art, if... Figure 3 As shown, with vertical installation, filtered impurities will inevitably flow back towards inlet 04, failing to meet the requirements for vertical installation. This valve device 1000, while possessing a filtering function, is not limited to installation in one direction; it can be installed horizontally as in the prior art, or as... Figure 3 As shown, it is installed vertically.

[0031] Furthermore, such as Figures 2-7 As shown, the connecting member 2 includes a first member 21 and a second member 22. The first member 21 is detachably connected to the connecting part 13, and the first member 21 is detachably connected to the second member 22. The first member 21 includes the aforementioned connecting channel 20 and partition part 230. The second member 22 includes the aforementioned impurity containing space 200, inner bottom wall 210, and inner side wall 220.

[0032] With the above-described structure of connecting member 2, the filter device 3 can be removed from valve body component 1 after the first component 21 and connecting part 13 are disassembled. After the second component 21 and second component 22 are disassembled, impurities in the impurity containing space 200 of the second component 22 can be easily cleaned. The separate arrangement of the first component 21 and second component 22 also facilitates the processing of the connecting channel 20 and the partition part 230.

[0033] Furthermore, such as Figure 6 As shown, the first component 21 includes a first threaded section 211, a second threaded section 212, and a partition portion 213. The connecting portion 13 is threadedly connected to the first threaded section 211, and the second threaded section 212 is threadedly connected to the second component 22. The partition portion 213 is located between the first threaded section 211 and the second threaded section 212, and includes a partition portion 230 and a communicating channel 20. With this configuration, the first component 21 is a single piece, which can be machined easily. One first component 21 directly forms two threaded sections for connection with the valve body component 1 and the second component 12, minimizing the increase in the number of parts.

[0034] In further proposals, such as Figure 6 and Figure 8 As shown, the partition portion 213 is circular, and the connecting channel 20 is a central through hole located in the partition portion 213. Thus, in Figure 3 As shown, the portion of the partition 213 located between the lower end W of the central through hole and the inner sidewall 220 serves as the aforementioned partition 230. To further clarify the partition 230, as shown... Figure 8 As shown, Figure 3 A schematic diagram of the right view of the partition portion 213 of the first component 21 in the AA direction. The partition portion 230 is the area M shown in the shaded part of the figure. The height H of the partition portion 230 is not less than 7mm. If the height is too low, the effect of preventing impurities from flowing back will be limited.

[0035] like Figure 3 and Figure 4As shown, the valve device 1000 also includes a valve core 5, a handle 4, and a valve stem 6. Operating the handle 4 allows the valve stem 6 to rotate the valve core 5 relative to the valve body component 1, thereby placing the valve core 5 in an open or closed position. The rotation direction of the valve core 5 is perpendicular to the first direction. Of course, operating the valve stem 6 via the handle 4 is only one implementation method for rotating the valve core 5, and not a limitation on the structure. The valve core 5 is at least partially located within the inner cavity of the valve body component 1. The valve core 5 includes a valve core cavity 50, a first opening 51, a second opening 52, and a third opening 53. The third opening 53 faces the mounting port 131. The filter device 3 passes through the third opening 131; here, "passes through" means that the filter device 3 is at least partially inserted into the valve core cavity 50 through the third opening 53 after passing through the mounting port 131. The filter device 3 is at least partially located within the valve core cavity 50. The first opening 51 and the second opening 52 are arranged opposite each other; here, "oppositely arranged" means that the centerlines of the first opening 51 and the second opening 52 are completely or approximately coincident. When the valve core 5 is in the open position, the fluid inlet port 111, the first opening 51, the valve core cavity 50, the second opening 52, and the fluid outlet port 121 are connected in sequence. The center lines of the fluid inlet port 111, the first opening 51, the valve core cavity 50, the second opening 52, and the fluid outlet port 121 are completely or approximately coincident, which can minimize the flow resistance of the fluid entering.

[0036] like Figure 3 As shown, when the valve core 5 is in the open position and the first opening 51 is facing downward, in the first direction, the height of the partition 230 is greater than the height of the first opening 51, so that the partition 230 can more reliably restrict the backflow of impurities.

[0037] like Figure 2 and Figure 3 As shown, the filter device 3 includes a filter section 31. When the valve core 5 is in the open position and the first opening 51 is facing downward, that is, in the first direction, the height of the partition 230 is greater than the height of the first opening 51. The filter section 31 connects the fluid inlet end 111 and the fluid outlet end 121. The connecting channel 20 is located between the filter section 31 and the partition 230 to prevent impurities collected in the impurity holding space from directly entering the fluid outlet end 121 through the connecting channel 20.

[0038] like Figures 2-5As shown, the filter device 3 includes a fixing frame 32, which is fixedly connected to the filter part 31. Specifically, the two can be injection molded together. Specifically, the fixing frame 32 can be an injection-molded portion formed by injection molding the filter part 31 with its edge as an insert. The fixing frame 32 includes a cylindrical part 321 and a lower fixing part 322. The lower fixing part 322 is limitedly connected to the connecting part 13. This limiting connection can be a fixed connection or a non-fixed connection, as long as the filter device 3 does not rotate relative to the valve body component 1 after the lower fixing part 322 is connected to the connecting part 13. The valve device 1000 also includes a sealing gasket 7, which is located between the lower fixing part 322 and the partition part 213. The sealing gasket 7 includes a flow hole 70, which connects the fluid inlet port 111 and the connecting channel 20. The flow hole 70 is arranged around the connecting channel 20. Here, "around" means that the inner wall of the flow hole 70 cannot block the connecting channel 20. The inner wall of the filter hole 70 and the inner wall forming the connecting channel 20 have the same shape and size, which is also within the range of the surrounding. As long as the connecting channel 20 is not blocked, the purpose is to reduce fluid resistance when the valve device 1000 is used.

[0039] The mounting bracket 32 ​​facilitates the limiting connection between the filter device 3 and the valve body component 1, while also allowing for... Figure 2 As shown, in a specific embodiment of the filter device 3, the filter section 31 is entirely located within the fixing frame 32. The fixing frame 32 includes an opening, which includes a left opening 323 and a right opening 324. The left opening 323 faces the fluid inlet port 111, and the right opening 324 faces the fluid outlet port 121. When the valve core 5 is in the open position, the fluid inlet port 111, the left opening 323, the right opening 324, and the fluid outlet port 121 are connected. The fixing frame 32 can improve the service life of the filter section 31 and improve the overall strength of the filter device 3. The right opening 324 and the left opening 323 are respectively opposite to the fluid inlet port 111 and the fluid outlet port 121, reducing flow resistance during use.

[0040] Furthermore, the mounting bracket 32 ​​includes a cover portion 322, and the filter portion 31 divides the interior of the mounting bracket 32 ​​into a first space 327 and a second space 328. When the valve core 5 is in the open position, the first space 327 faces the first opening 51, and the second space 328 faces the second opening 52. The cover portion 322 is located between the second space 328 and the partition portion 213, and the cover portion 322 blocks one end of the second space 328 facing the partition portion 213. The connecting channel 20 and the partition portion 230 are located between the first space 327 and the impurity containing space 200. The cover portion 322 further prevents impurities in the impurity containing space 200 from entering the second space 328 and flowing to the fluid outlet port 121, and also prevents impurities carried by the fluid from flowing through the fluid inlet port 121 and then through the first space 327 to the right end of the second space 328. Figure 2(As shown) Enter the second space 328.

[0041] like Figure 3 and Figure 4 As shown, since the first component 21 and the second component 22 are detachably connected, to prevent leakage at the connection point, the connecting component 2 further includes a sealing ring 24. The sealing ring 24 is sleeved on the second component 22. The second component 22 includes an operating section 221 and a third threaded section 222. The third threaded section 222 is threadedly connected to the second threaded section 212. The sealing ring 24 abuts against and seals against the first component 21 and the second component 22. Specifically, the operating section 221 may include an end face facing the first component, and the sealing ring 24 is seated on the end face, abutting against and sealing against the first component 21 and the second component 22. Alternatively, it can be as follows: Figure 7 As shown, the outer wall of the second component 22 includes an annular groove 223, and the sealing ring 24 is sleeved in the annular groove 223 and abuts against the inner wall of the first component 21 for sealing.

[0042] The aforementioned valve body component 1 includes a first valve body 11 and a second valve body 12. The first valve body 11 and the second valve body 12 are made of brass. The first component 21 and the second component 22 are also made of brass. The first valve body 11 includes the aforementioned first port portion 110. The second valve body 12 includes the aforementioned connecting portion 13 and the second port portion 120. The first port portion 110 and the second port portion 120 are coaxially arranged. Brass is easy to machine and gives each component a certain thickness, which is convenient to meet the strength requirements of the valve device 1000.

[0043] This application also provides a heat pump system, such as Figure 9 As shown, the heat pump system includes a water heater body 300 and an inlet valve. The fluid outlet port of the inlet valve is connected to the water heater body 300. The inlet valve is any of the valve devices 1000 mentioned above.

[0044] Because this heat pump system uses the valve device 1000 of this application, the relative positions of the inlet valve and the water heater body 300 during installation are more flexible than those in the prior art.

[0045] This application also provides a heat pump system, such as Figure 9 As shown, the heat pump system includes a water heater body 300 and an inlet valve. The fluid outlet port of the inlet valve is connected to the water heater body 300. The inlet valve is any of the valve devices 1000 described in this application.

[0046] Because this heat pump system uses the valve device 1000 of this application, the relative positions of the inlet valve and the water heater body 300 during installation are more flexible than those in the prior art.

[0047] The valve device 1000 in this heat pump system serves both as an on / off switch to control water supply to the water heater body and as a filter for impurities. Furthermore, when the valve device 1000 needs to be installed horizontally, only one valve device 1000 needs to be installed between the water collector 500 and the water heater body 300, eliminating the need to install a filter ball valve and a vertically installed inlet valve on the connection pipe between the water heater body and the water collector. This reduces the number of system components, and the valve device can be installed horizontally or vertically, making the installation space of the heat pump system more flexible and diverse than in the prior art.

[0048] This application discloses a heat pump system, including a water heater body 300, a valve device 1000, and a water collector 500, such as... Figures 1-7 As shown, the valve device 1000 includes a valve body component 1, a filter device 3, and a connecting member 2. The valve body component 1 includes a first port portion 110 and a second port portion 120. The first port portion 110 includes a fluid inlet port 111, and the second port portion 120 includes a fluid outlet port 121. The filter device 3 is at least partially located between the fluid inlet port 111 and the fluid outlet port 121. The connecting member 2 includes a first member 21 and a second member 22. The valve body component 1 includes a connecting portion 13, which includes a mounting port 131. The first member 21 is detachably connected to the connecting portion 13. After component 21 is detached from the connecting part 13, the filter device 3 can be disengaged from the valve body component 1 through the mounting port 131 of the connecting part 13; the second component 22 is detachably connected to the first component 21, the second component 22 includes an impurity containing space 200, the first component 21 includes a connecting channel 20 and a baffle 230, the connecting channel 20 connects the fluid inlet port 111 and the impurity containing space 200, the fluid outlet port 121 faces the water heater body 300, the second port 120 is fixedly connected to the water heater body 300, the fixing here includes detachable fixing, and the first port 110 is connected to the water collector 500.

[0049] The valve device 1000 in this heat pump system serves both as an on / off switch to control water supply to the water heater body and as a filter for impurities. Furthermore, when the valve device 1000 needs to be installed horizontally, only one valve device 1000 needs to be installed between the water collector 500 and the water heater body 300. This eliminates the need to install a filter ball valve and a vertically installed inlet valve on the connecting pipe between the water heater body 300 and the water collector 500. This reduces the number of system components, and the valve device can be installed horizontally or vertically, making the installation space of the heat pump system more flexible and diverse than in the prior art.

[0050] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention. All technical features and improvements that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
