Description

Technical Field

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

[0002] In related technologies, water valves within hydraulic modules possess both shut-off and conduction functions. The connection between the water valve and the workpiece within the hydraulic module is a threaded connection. For example, when the workpiece is a pipe, both ends of the water valve are equipped with internal or external threads (such as pipe threads or tapered threads) that match the pipe's threaded portion, connecting to the pipe by rotating the water valve. However, this connection structure requires reserved installation space within the hydraulic module, and the water valve is installed and disassembled using installation equipment (such as a wrench), resulting in a large footprint for the hydraulic module and a complex valve structure that is difficult to disassemble. Utility Model Content

[0003] This utility model provides a water valve, a hydraulic module, and a heating unit to solve the technical problems of water valve installation requiring a pre-set installation space in the hydraulic module, resulting in a large area occupied by the hydraulic module, and water valve structure being complex and difficult to disassemble.

[0004] This utility model provides a water valve including a first connector and a second connector. The first connector has a first connecting portion, and the second connector has a second connecting portion. The first connecting portion is one of a male connector and a female connector, and the second connecting portion is one of a male connector and a female connector. The first connecting portion is configured to connect with a third connecting portion of a first workpiece, and the third connecting portion is the other of the male connector and the female connector. The second connecting portion is configured to connect with a fourth connecting portion of a second workpiece, and the fourth connecting portion is the other of the male connector and the female connector. The female connector has an insertion space, and the side wall surrounding the insertion space has a first slot communicating with the insertion space. The outer side surface of the male connector has a second slot, and the male connector is configured to be inserted into the insertion space. A first locking member is detachably inserted through the first slot and the second slot to fix the first connector and the first workpiece through the first connecting portion and the third connecting portion. A second locking member is detachably inserted through the first slot and the second slot to fix the second connector and the second workpiece through the second connecting portion and the fourth connecting portion.

[0005] Thus, by setting a first slot on the water valve connector and a second slot on the workpiece connected to the water valve, the locking element can fix the connector and the workpiece after being inserted into the first and second slots, thereby securing the water valve. During disassembly, the locking element can be pulled out of the first and second slots to separate the water valve from the workpiece. Therefore, the installation of the water valve does not require the involvement of installation equipment, eliminating the need to reserve space in the hydraulic module to accommodate such equipment, reducing the area occupied by the hydraulic module, and simplifying the disassembly and installation of the water valve.

[0006] In some embodiments, both the first clip and the second clip include two clamping arms and a connecting arm. The two clamping arms are respectively connected to the opposite ends of the connecting arm. The clamping arms pass through the first slot. Each clamping arm is provided with a clamping part. The clamping part is configured to be embedded in the second slot. The two clamping parts are configured to clamp the third connecting part and the fourth connecting part respectively.

[0007] In this way, the stability of the first card connecting the first connecting part and the third connecting part can be improved, as can the stability of the second card connecting the second connecting part and the fourth connecting part.

[0008] In some embodiments, the shape of the clamping portion is adapted to the shape of the periphery of the male end where the second slot is provided.

[0009] In this way, the clamping part can better clamp the third connecting part and the fourth connecting part.

[0010] In some embodiments, the second connecting portion and the third connecting portion are male connectors, each male connector having at least one limiting groove spaced apart from the second slot. The water valve includes at least one sealing ring, each sealing ring being embedded in a corresponding limiting groove. The sealing rings are configured to seal the first connecting portion and the third connecting portion, and to seal the second connecting portion and the fourth connecting portion.

[0011] Thus, by setting a limiting groove on the male end and embedding the sealing ring in the limiting groove, the sealing performance of the first and third connecting parts, as well as the sealing performance of the second and fourth connecting parts, can be improved.

[0012] In some embodiments, the sealing ring is an O-ring.

[0013] In this way, the sealing performance of the first and third connecting parts can be improved, as well as the sealing performance of the second and fourth connecting parts.

[0014] In some embodiments, the water valve includes a valve body, with the first connector and the second connector disposed at both ends of the valve body. The valve body and the first workpiece are detachably connected via the first connecting portion and the third connecting portion, and the valve body and the second workpiece are detachably connected via the second connecting portion and the fourth connecting portion.

[0015] In this way, by detachably connecting the workpiece to the valve body, the installation and removal of the water valve becomes simple and quick, facilitating maintenance and replacement.

[0016] In some embodiments, the water valve includes a valve handle, a valve stem, and a valve ball. The valve handle is fixedly connected to the valve ball via the valve stem. The valve body has a receiving cavity, and the valve ball is configured to be rotatably connected to the valve body in the receiving cavity via the valve handle.

[0017] This allows the valve ball of the water valve to be controlled by the valve handle, thus enabling the water valve to be closed or opened, and the valve opening degree to be adjusted, thereby precisely controlling the water flow rate to meet different usage needs.

[0018] In some embodiments, the valve ball is provided with a through first flow channel. When the first workpiece and the second workpiece are fixed to the first connector and the second connector respectively, the valve handle drives the valve ball to rotate so that the first workpiece communicates with the second workpiece through the first flow channel.

[0019] Thus, by providing a through first flow channel on the valve ball, when the water valve is opened, the first workpiece and the second workpiece can be connected through the first flow channel, allowing the liquid in the first workpiece to flow into the second workpiece through the first flow channel.

[0020] In some embodiments, the water valve includes a filter screen and a fixed cover. The valve body has a through hole communicating with a receiving cavity. The valve ball has a second flow channel. The through hole communicates with the first flow channel through the second flow channel. The fixed cover extends into the through hole and is detachably connected to the valve body. The fixed cover is configured to extend into the second flow channel and abut against the filter screen, such that the filter screen is fixedly connected to the valve ball in the first flow channel.

[0021] Thus, by installing a filter screen in the first flow channel, impurities in the liquid flowing through the water valve can be filtered out, preventing impurities from entering the hydraulic module and affecting its operation. Furthermore, the filter screen is fixed inside the first flow channel by a retaining cover, so removing the filter screen is quick and easy; simply remove the retaining cover.

[0022] In some embodiments, the water valve includes a positioning seat and a fixing seat, which are respectively disposed on opposite outer sides of the valve body.

[0023] Thus, by setting a positioning seat on the water valve, the position of the water valve on the hydraulic module can be determined, avoiding deviations during water valve installation and improving installation efficiency; by setting a fixing seat on the water valve, the stability of the water valve in the hydraulic module can be further improved.

[0024] This utility model provides a hydraulic module, which includes the water valve described in any of the above embodiments.

[0025] In some embodiments, the first workpiece includes a first pipe, the third connecting portion is disposed at one end of the first pipe, and the first connector and the first pipe are connected through the first connecting portion and the third connecting portion; and / or the second workpiece includes a second pipe, the fourth connecting portion is disposed at one end of the second pipe, and the second connector and the second pipe are connected through the second connecting portion and the fourth connecting portion; and / or the second workpiece includes a heat exchanger, the fourth connecting portion is disposed on the heat exchanger, and the second connector and the heat exchanger are connected through the second connecting portion and the fourth connecting portion.

[0026] Thus, by connecting the first and second pipes with a water valve, the flow rate of domestic water within the pipes can be controlled. By connecting the water valve to the heat exchanger, the domestic water entering the heat exchanger can be controlled, thereby improving the heat exchanger's heat exchange efficiency.

[0027] In some embodiments, the second workpiece includes a water tank, the fourth connecting part is disposed on the water tank, and the water valve and the water tank are connected through the second connecting part and the fourth connecting part.

[0028] In this way, by connecting the water valve and the water tank, it is possible to control the flow of domestic water from the hydraulic module into the water tank or control the flow of domestic water from the water tank into the hydraulic module, thereby improving the stability of the hydraulic module.

[0029] In some embodiments, the hydraulic module includes an expansion tank, the second component includes a third pipe, one end of the third pipe is connected to the expansion tank, the fourth connection is disposed at the other end of the third pipe, and the water valve and the third pipe are connected through the second connection and the fourth connection.

[0030] In this way, by connecting the water valve to the expansion tank, excess water in the hydraulic module can flow into the expansion tank through the water valve, thereby preventing the hydraulic module from being too pressurized to a certain extent.

[0031] This utility model provides a heating unit, which includes the hydraulic module described in any of the above embodiments.

[0048] In related technologies, water valves are equipped with connectors, and the connector design generally adopts a threaded connection method. This, to some extent, limits the installation and maintenance efficiency of hydraulic systems. Because threaded connections require specialized tools for installation and disassembly, the operation process is relatively complex and prone to problems such as leakage. This connection method not only prolongs installation time and increases labor costs, but also inconveniences maintenance personnel and reduces work efficiency when equipment malfunctions and requires repair.

[0049] To solve the above-mentioned technical problems, this utility model provides a water valve 100.

[0050] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides a water valve 100 comprising a first connector 10 and a second connector 20. The first connector 10 is provided with a first connecting portion 11, and the second connector 20 is provided with a second connecting portion 21. The first connecting portion 11 is one of a male connector 30 and a female connector 40, and the second connecting portion 21 is one of a male connector 30 and a female connector 40. The first connecting portion 11 is configured to connect with a third connecting portion 210 of a first workpiece 200, which is the other of a male connector 30 and a female connector 40. The second connecting portion 21 is configured to connect with a fourth connecting portion 310 of a second workpiece 300, which is a male connector 30 and a female connector 40. The other end of the head 40; the female head 40 has an insertion space 41 inside, and the side wall surrounding the insertion space 41 has a first slot 42 communicating with the insertion space 41. The outer side surface of the male head 30 has a second slot 31. The male head 30 is configured to be inserted into the insertion space 41. The first locking member 50 is detachably inserted through the first slot 42 and the second slot 31 so that the first connector 10 and the first workpiece 200 are fixedly connected through the first connecting part 11 and the third connecting part 210. The second locking member 60 is detachably inserted through the first slot 42 and the second slot 31 so that the second connector 20 and the second workpiece 300 are fixedly connected through the second connecting part 21 and the fourth connecting part 310.

[0051] Thus, by providing a first slot 42 at the connector of the water valve 100 and a second slot 31 on the workpiece connected to the water valve 100, the locking element can fix the connector and the workpiece after being inserted into the first slot 42 and the second slot 31, thereby securing the water valve 100. During disassembly, the locking element can be pulled out from the first slot 42 and the second slot 31 to separate the water valve 100 from the workpiece. Therefore, no installation equipment is required during the installation of the water valve 100, eliminating the need to reserve space in the hydraulic module 1000 to accommodate the installation equipment, reducing the area occupied by the hydraulic module 1000, and simplifying the disassembly and installation of the water valve 100.

[0052] The water valve 100 can be applied to, but is not limited to, the hydraulic module 1000. The hydraulic module 1000 can be applied to a heating unit. In one embodiment, the heating unit may include an outdoor unit, a domestic water tank 340, a gas boiler, a zone one system, and a zone two system. The hydraulic module 1000 can be connected to the outdoor unit, the domestic water tank 340, the gas boiler, the zone one system, and the zone two system via pipes. The outdoor unit may include a heat pump system, which can heat cold water into hot water and distribute the hot water to the hydraulic module 1000.

[0053] A gas boiler can use the heat generated during gas combustion to heat cold water to produce hot water. The hot water output from the gas boiler is distributed by a hydraulic module 1000.

[0054] Optionally, the heating unit also includes solar panels, and the hydraulic module 1000 is connected to the solar panels via pipes. The solar panels are used to generate electricity using solar energy, and use the electricity to heat cold water to form hot water, which can be transmitted to the hydraulic module 1000 for distribution.

[0055] Firstly, the hydraulic module 1000 can deliver hot water to the coil inside the domestic water tank 340. The hot water transfers heat through the coil to the domestic water in the domestic water tank 340, raising the temperature of the domestic water. The domestic water tank 340 can be connected to water outlet valves 100 such as faucets and shower heads, and the heated domestic water can be supplied to users through these outlet valves.

[0056] Secondly, the hydraulic module 1000 can deliver hot water to a zone system, which may include heaters suspended from the indoor ceiling, including but not limited to fan coil units (FCUs). The fan coil units can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0057] Thirdly, the hydraulic module 1000 can deliver hot water to the Zone 2 system, which may include underfloor heating and / or radiators. Underfloor heating can radiate the heat from the hot water to the floor, while radiators can radiate the heat from the hot water into the room, thereby raising the temperature of the floor and the room.

[0058] The hydraulic module 1000 can integrate various components installed by the client, facilitating installation and maintenance. Optionally, in one embodiment, the hydraulic module 1000 includes structural components and system components. Structural components include, but are not limited to: chassis, frame, door panel, top cover, decorative ring, etc.; system components include, but are not limited to: water valve 100, magnetic filter, buffer energy storage tank, mixing valve (three-way valve), water pump, air vent valve, safety valve, water pressure gauge, expansion tank 400, anti-backflow valve, constant pressure water supply valve, soft water filter, etc.

[0059] The workpiece can be any component in the hydraulic module 1000 that needs to be installed and connected to the water valve 100. The workpiece may include, but is not limited to, the drain valve 100, cold water delivery pipes, and hot water delivery pipes.

[0060] Specifically, the water valve 100 includes a first connector 10 and a second connector 20, which can be used to connect a first workpiece 200 and a second workpiece 300. The first connector 10 has a first connecting portion 11, which can be a male connector 30 or a female connector 40; the second connector 20 has a second connecting portion 21, which can be a male connector 30 or a female connector 40.

[0061] The first workpiece 200 is provided with a third connecting portion 210, and the first connecting portion 11 can be connected to the third connecting portion 210. When the first connecting portion 11 is a male connector 30, the third connecting portion 210 is a female connector 40, and when the first connecting portion 11 is a female connector 40, the third connecting portion 210 is a male connector 30. The second workpiece 300 is provided with a fourth connecting portion 310, and the second connecting portion 21 can be connected to the fourth connecting portion 310. When the second connecting portion 21 is a male connector 30, the fourth connecting portion 310 is a female connector 40, and when the second connecting portion 21 is a female connector 40, the fourth connecting portion 310 is a male connector 30.

[0062] The female connector 40 includes an insertion space 41, which allows the male connector 30 to be inserted. A first slot 42 communicating with the insertion space 41 is provided on the side wall of the insertion space 41. For example, when the first connecting part 11 or the second connecting part 21 is a female connector 40, the first slot 42 is provided on the first connecting part 11 and the second connecting part 21; when the third connecting part 210 or the fourth connecting part 310 is a female connector 40, the first slot 42 is provided on both the third connecting part 210 and the fourth connecting part 310.

[0063] A second slot 31 is provided on the outer surface of the male connector 30, and when the male connector 30 is inserted into the insertion space 41 and fixed, the first slot 42 can be disposed opposite to the second slot 31. For example, when the first connecting part 11 or the second connecting part 21 is a male connector 30, the second slot 31 is disposed on the first connecting part 11 and the second connecting part 21; when the third connecting part 210 or the fourth connecting part 310 is a male connector 30, the first slot 42 is disposed on the third connecting part 210 and the fourth connecting part 310.

[0064] The water valve 100 includes a first locking member 50 and a second locking member 60. The first locking member 50 and the second locking member 60 are detachably connected to the first locking groove 42 and the second locking groove 31. When disassembling the water valve 100 and the first workpiece 200 or the second workpiece 300, the first locking member 50 and the second locking member 60 can be removed, thereby releasing the connection lock between the water valve 100 and the first workpiece 200 or the second workpiece 300, allowing the water valve 100 to be separated from the first workpiece 200 or the second workpiece 300. During installation, the male connector 30 can be inserted into the insertion space 41 of the female connector 40, and the first slot 42 and the second slot 31 can be aligned and connected. Then, the first locking piece 50 or the second locking piece 60 can be inserted into the first slot 42 and the second slot 31 to fix the first connecting part 11 and the third connecting part 210, or fix the second connecting part 21 and the fourth connecting part 310, thereby fixing the first connector 10 and the first workpiece 200, or fixing the second connector 20 and the second workpiece 300. In summary, this can reduce the operating space to a certain extent and reduce the difficulty of after-sales replacement of parts. The whole process is basically tool-free. The first locking piece 50 and the second locking piece 60 include, but are not limited to, locking pins ( Figure 4 ),card( Figure 5 )wait.

[0065] It is understood that in the embodiment shown in the figure, the card is in the form of a pin, and the connecting arm 62 can serve as an operating part, which can facilitate the user to operate the card for assembly and disassembly.

[0066] In the embodiment shown in the figure, the card is in the form of a card and also includes a handle. The handle is connected to the side of the connecting arm 62 away from the clamping part 611. The handle allows the user to easily operate the card for assembly and disassembly.

[0067] Please see Figure 4 and Figure 5 In some embodiments, the first clip 50 and the second clip both include two clamping arms 61 and a connecting arm 62. The two clamping arms 61 are respectively connected to the two opposite ends of the connecting arm 62. The clamping arms 61 pass through the first slot 42. Each clamping arm 61 is provided with a clamping part 611. The clamping part 611 is configured to be embedded in the second slot 31. The two clamping parts 611 are configured to clamp the third connecting part 210 and the fourth connecting part 310 respectively.

[0068] In this way, the stability of the first card 50 connecting the first connecting part 11 and the third connecting part 210 can be improved, and the stability of the second card 60 connecting the second connecting part 21 and the fourth connecting part 310 can be improved.

[0069] Specifically, when the first connector 10 and the first workpiece 200 are fixedly connected, or the second connector 20 and the second workpiece 300 are connected, and the first connecting part 11 and the second connecting part 21 are female heads 40, the clamping part 611 can be embedded in the second slot 31. The two clamping parts 611 clamp the third connecting part 210 or the fourth connecting part 310, so that after the third connecting part 210 is inserted into the insertion space 41 of the first connecting part 11 or after the fourth connecting part 310 is inserted into the insertion space 41 of the second connecting part 21, the clamping part 611 clamps and fixes the third connecting part 210 at the second slot 31, so that the third connecting part 210 is not easy to or will not shake. Or the clamping part 611 clamps and fixes the fourth connecting part 310 at the second slot 31, so that the fourth connecting part 310 is not easy to or will not shake. Meanwhile, since the clamping arm 61 passes through the first slot 42 and the clamping part 611 is embedded in the second slot 31, the third connecting part 210 or the fourth connecting part 310 cannot be pulled out from the insertion space 41. This can improve the stability of the first clamping member 50 connecting the first connector 10 and the second workpiece 300 connecting the second connector 20, thereby realizing the fixed connection between the first connector 10 and the first workpiece 200 through the first connecting part 11 and the third connecting part 210, and the fixed connection between the second connector 20 and the second workpiece 300 through the second connecting part 21 and the fourth connecting part 310.

[0070] Please see Figure 2 In some embodiments, the shape of the clamping part 611 is adapted to the shape of the periphery of the male head 30 where the second slot 31 is provided.

[0071] In this way, the clamping part 611 can better clamp the third connecting part 210 and the fourth connecting part 310.

[0072] Specifically, in one embodiment, referring to Figures 2 and 3, when the second connecting part 21 is a male head 30, the periphery of the second slot 31 of the second connecting part 21 is cylindrical, and the clamping part 611 is an arc shape that matches the above-mentioned cylindrical shape, so that the clamping part 611 can better fit with the second connecting part 21, the contact area between the clamping part 611 and the second connecting part 21 is large, reducing or avoiding the shaking of the second connecting part 21, and making the clamping of the second connecting part 21 more stable.

[0073] It is understood that in other embodiments, the periphery of the second slot 31 provided by the second connecting part 21 may be in other shapes, such as square column, polygonal column, etc., and is not limited to cylindrical.

[0074] Please see Figure 2 In some embodiments, the second connecting portion 21 and the third connecting portion 210 are male heads 30, and the male head 30 is provided with at least one limiting groove 32. The limiting groove 32 is separated from the second slot 31. The water valve 100 includes at least one sealing ring 70. Each sealing ring 70 is embedded in a corresponding limiting groove 32. The sealing ring 70 is configured to seal the connection between the first connecting portion 11 and the third connecting portion 210, and to seal the connection between the second connecting portion 21 and the fourth connecting portion 310.

[0075] Thus, by providing a limiting groove 32 on the male connector 30 and embedding the sealing ring 70 in the limiting groove 32, the sealing performance of the first connecting part 11 and the third connecting part 210, as well as the sealing performance of the second connecting part 21 and the fourth connecting part 310, can be improved.

[0076] Specifically, please combine Figure 1 When the second connecting portion 21 and the third connecting portion 210 are male connectors 30, the male connector 30 is provided with at least one limiting groove 32, which is used to limit the sealing ring 70 so that the sealing ring 70 will not or cannot easily move. The male connector 30 is provided with a second retaining groove 31, that is, the second connecting portion 21 and the third connecting portion 210 are provided with a second retaining groove 31, which is separated from the limiting groove 32. Correspondingly, the first connector 10 includes a first connecting portion 11, the second connecting portion 21 is a female connector 40, and the second workpiece 300 includes a fourth connecting portion 310, which is a female connector 40, that is, the first connecting portion 11 and the fourth connecting portion 310 are provided with a first retaining groove 42. The first clip 50 can pass through the third connecting part 210 of the first workpiece 200 and fit with the first connecting part 11 of the first connector 10, and the second clip 60 can pass through the fourth connecting part 310 of the second workpiece 300 and fit with the second connecting part 21 of the second connector 20, so that the first workpiece 200 and the first connector 10, the second workpiece 300 and the second connector 20 can be fixedly connected.

[0077] Each sealing ring 70 is embedded in a corresponding limiting groove 32, so that the sealing ring 70 can be limited by the limiting groove 32. The position of the sealing ring 70 will not change or is not easy to change, which reduces the occurrence of sealing failure or reduced sealing performance due to the displacement of the sealing ring 70 to a certain extent.

[0078] The number of sealing rings 70 and limiting grooves 32 can be determined according to specific requirements (such as pressure requirements). In the figure, the first connector 10 and the first workpiece 200 are sealed together by two sealing rings 70, and the second connector 20 and the second workpiece 300 are sealed together by two sealing rings 70. The two sealing rings 70 are respectively embedded in the two limiting grooves 32.

[0079] In one example, the sealing ring 70 can be a rubber ring or a silicone ring, which can improve the sealing between the first connecting part 11 and the second connecting part 21.

[0080] In some embodiments, the sealing ring 70 is an O-ring 70.

[0081] In this way, the sealing performance of the first connecting part 11 and the third connecting part 210 can be improved, as well as the sealing performance of the second connecting part 21 and the fourth connecting part 310 can be improved.

[0082] Specifically, when the first connecting part 11 is a female head 40 and the third connecting part 210 is a male head 30, the cross-section of the O-ring 70 is O-shaped or circular. When the O-ring 70 is compressed by the first connecting part 11 and the third connecting part 210, it can extend and deform along the outer wall of the third connecting part 210 and the inner wall of the first connecting part 11, thereby increasing the contact area and bonding force between the O-ring 70 and the first connecting part 11 and the third connecting part 210, thus improving the sealing performance.

[0083] Please see Figure 2 In some embodiments, the water valve 100 includes a valve body 80, a first connector 10 and a second connector 20 disposed at both ends of the valve body 80, the valve body 80 and the first workpiece 200 are detachably connected by a first connecting part 11 and a third connecting part 210, and the valve body 80 and the second workpiece 300 are detachably connected by a second connecting part 21 and a fourth connecting part 310.

[0084] Thus, by detachably connecting the workpiece to the valve body 80, the installation and removal of the water valve 100 becomes simple and quick, facilitating maintenance and replacement.

[0085] Specifically, the water valve 100 includes a valve body 80. The valve body 80 is the main structure of the water valve 100, serving to house and support other components of the water valve 100. For example, the valve body 80 houses and supports components such as the ball, valve seat, and valve stem 110, ensuring the normal operation of the water valve 100. The material selection for the valve body 80 depends on factors such as the corrosiveness, temperature, and pressure of the medium. For example, the material of the valve body 80 can be carbon steel, stainless steel, or alloy steel.

[0086] The first connector 10 and the second connector 20 can be disposed at opposite ends of the valve body 80, so that the valve body 80 can be detachably connected to the first workpiece 200 through the first connecting part 11 and the third connecting part 210, and the valve body 80 can be detachably connected to the second workpiece 300 through the second connecting part 21 and the fourth connecting part 310.

[0087] Please see Figure 2 In some embodiments, the water valve 100 includes a valve handle 90, a valve stem 110, and a valve ball 120. The valve handle 90 is fixedly connected to the valve ball 120 via the valve stem 110. The valve body 80 is provided with a receiving cavity 81. The valve ball 120 is configured to be rotatably connected to the valve body 80 in the receiving cavity 81 by the valve handle 90.

[0088] In this way, the valve ball 120 of the water valve 100 can be controlled by the valve handle 90, thereby opening or closing the water valve 100 and adjusting the valve opening to precisely control the water flow and meet different usage needs.

[0089] Specifically, the water valve 100 includes a valve handle 90, a valve stem 110, and a valve ball 120. The water valve 100 can control the flow of fluid through the cooperation of the valve handle 90, valve stem 110, and valve ball 120. The valve handle 90 is usually located outside the water valve 100 and can be operated by the user. The water valve 100 can be opened and closed by rotating or pushing the valve handle 90.

[0090] The valve handle 90 is fixedly connected to the valve ball 120 via the valve stem 110. The valve stem 110 is a component that connects the valve handle 90 and the valve ball 120, and can transmit the rotation or push-pull action of the valve handle 90 to the valve ball 120, so that the valve ball 120 rotates within the valve body 80.

[0091] The valve body 80 is provided with a receiving cavity 81, and the valve ball 120 is disposed in the receiving cavity 81. The valve ball 120 usually has one or more through holes 82. When the valve ball 120 rotates to a specific position, the through holes 82 can communicate with or block the first connecting part 11 and the second connecting part 21 of the valve body 80, thereby controlling the flow of fluid.

[0092] Please see Figure 2In some embodiments, the valve ball 120 is provided with a through first flow channel 121. When the first workpiece 200 and the second workpiece 300 are fixed to the first connector 10 and the second connector 20 respectively, the valve handle 90 drives the valve ball 120 to rotate so that the first workpiece 200 communicates with the second workpiece 300 through the first flow channel 121.

[0093] Thus, by providing a through first flow channel 121 on the valve ball 120, when the water valve 100 is opened, the first workpiece 200 and the second workpiece 300 can be connected by the first flow channel 121, so that the liquid of the first workpiece 200 flows into the second workpiece 300 through the first flow channel 121.

[0094] Specifically, a first flow channel 121 is provided on the water valve 100, penetrating the valve ball 120, allowing fluid to flow through. Furthermore, when the first workpiece 200 and the second workpiece 300 are respectively fixed to the first connector 10 and the second connector 20, the valve handle 90 can drive the valve ball 120 to rotate, allowing the first workpiece 200 to communicate with the second workpiece 300 through the first flow channel 121, thereby allowing domestic water in the first workpiece 200 to flow into the second workpiece 300 through the first flow channel 121.

[0095] Please see Figure 2 In some embodiments, the water valve 100 includes a filter screen 130 and a fixing cover 140. The valve body 80 is provided with a through hole 82 communicating with the receiving cavity 81. The valve ball 120 is provided with a second flow channel 122. The through hole 82 communicates with the first flow channel 121 through the second flow channel 122. The fixing cover 140 extends into the through hole 82 and is detachably connected to the valve body 80. The fixing cover 140 is configured to extend into the second flow channel 122 and abut against the filter screen 130, so that the filter screen 130 is fixedly connected to the valve ball 120 in the first flow channel 121.

[0096] Thus, by setting a filter screen 130 in the first flow channel 121, impurities in the liquid flowing through the water valve 100 can be filtered out, preventing impurities from entering the hydraulic module 1000 and affecting its operation. Furthermore, the filter screen 130 is fixed inside the first flow channel 121 by a fixing cover 140, so that when removing the filter screen 130, only the fixing cover 140 needs to be removed to take it out, which is convenient and quick.

[0097] Specifically, the water valve 100 includes a filter screen 130 and a fixing cover 140. The filter screen 130 is used to filter domestic water flowing through the water valve 100, and the fixing cover 140 is used to fix the filter screen 130 inside the water valve 100. The valve body 80 is provided with a through hole 82 communicating with the receiving cavity 81. The shape of the through hole 82 is adapted to the shape of the fixing cover 140, allowing the fixing cover 140 to extend into the through hole 82 and be detachably connected to the valve body 80. For example, the fixing cover 140 and the valve body 80 can be fixed by a threaded connection. An internal or external thread (such as a pipe thread or a tapered thread) matching the threaded portion of the inner wall of the through hole 82 is provided on the outer side of the fixing cover 140, and the fixing cover 140 is connected to the through hole 82 by rotating it.

[0098] The valve ball 120 is provided with a second flow channel 122, which is connected to the first flow channel 121 and the through hole 82 respectively. Thus, the through hole 82 is connected to the first flow channel 121 through the second flow channel 122. The filter screen 130 can be disposed on the end face of the fixed cover 140. When the fixed cover 140 extends into the through hole 82 and the second flow channel 122, it can cooperate with the valve ball 120 to hold the filter screen 130, so that the filter screen 130 is fixedly connected to the valve ball 120 in the first flow channel 121.

[0099] Please see Figures 6 to 8 In some embodiments, the water valve 100 includes a positioning seat 150 and a fixing seat 160, which are respectively disposed on opposite outer sides of the valve body 80.

[0100] Thus, by setting a positioning seat 150 on the water valve 100, the position of the water valve 100 on the hydraulic module 1000 can be determined, avoiding deviations during the installation of the water valve 100 and improving installation efficiency; by setting a fixing seat 160 on the water valve 100, the stability of the water valve 100 in the hydraulic module 1000 can be further improved.

[0101] Specifically, the water valve 100 also includes a positioning seat 150 and a fixing seat 160. The positioning seat 150 can position the water valve 100 within the hydraulic module 1000, ensuring accurate installation of the water valve 100 within the hydraulic module 1000. The fixing seat 160 can fix the water valve 100 onto the hydraulic module 1000. The fixing seat 160 has fixing holes through which the water valve 100 can be fixed to the bracket of the hydraulic module 1000. The positioning seat 150 has positioning posts, which position the water valve 100 within the hydraulic module 1000.

[0102] In some implementations, such as Figure 6 The fixing seat 160 can be set on opposite sides of the valve body 80, so that the water valve 100 can be fixed by the fixing seat 160 on both sides.

[0103] In some implementations, such as Figure 7 As shown, the fixing seat 160 can be set on one side of the water valve 100, so that the water valve 100 can be fixed by the fixing seat 160 on one side.

[0104] In some implementations, such as Figure 8 As shown, the fixing seat 160 can be set on one side of the water valve 100, and the positioning seat 150 can be set on the other side of the water valve 100, so that the water valve 100 is fixed by the fixing seat 160 on one side and the water valve 100 is positioned by the positioning seat 150 on one side.

[0105] Please refer to it again. Figure 3 The hydraulic module 1000 provided in this embodiment includes the water valve 100 of any of the above embodiments.

[0106] Specifically, the hydraulic module 1000 may include a water valve 100, a first workpiece 200, and a second workpiece 300, as described in any of the above embodiments. The water valve 100 may include a first connecting portion 11 and a second connecting portion 21, the first workpiece 200 may include a third connecting portion 210, and the second workpiece 300 may include a fourth connecting portion 310.

The first locking member 50 is detachably connected through a first locking groove 42 and a second locking groove 31 so that the first connector 10 and the first workpiece 200 are fixedly connected through a first connecting part 11 and a third connecting part 210. The second locking member 60 is detachably connected through a first locking groove 42 and a second locking groove 31 so that the second connector 20 and the second workpiece 300 are fixedly connected through a second connecting part 21 and a fourth connecting part 310.

The female connector 40 has an insertion space 41, and the sidewall surrounding the insertion space 41 has a first slot 42 communicating with the insertion space 41. The outer surface of the male connector 30 has a second slot 31. The male connector 30 can be inserted into the insertion space 41 of the female connector 40. Correspondingly, the water valve 100 includes a first locking member 50 and a second locking member 60. The first locking member 50 is detachably inserted through the first slot 42 and the second slot 31 to fix the first connector 10 and the first workpiece 200 together via the first connecting portion 11 and the third connecting portion 210. The second locking member 60 is detachably inserted through the first slot 42 and the second slot 31 to fix the second connector 20 and the second workpiece 300 together via the second connecting portion 21 and the fourth connecting portion 310.

[0108] In another embodiment, the first connecting portion 11 and the second connecting portion 21 are male connectors 30, and the third connecting portion 210 and the fourth connecting portion 310 are female connectors 40. The female connector 40 has an insertion space 41, and the sidewall surrounding the insertion space 41 has a first slot 42 communicating with the insertion space 41. The outer surface of the male connector 30 has a second slot 31. The male connector 30 can be inserted into the insertion space 41 of the female connector 40. Correspondingly, the water valve 100 includes a first locking member 50 and a second locking member 60.

The second locking member 60 is detachably inserted through the first slot 42 and the second slot 31 to fix the second connector 20 and the second workpiece 300 through the second connecting portion 21 and the fourth connecting portion 310.

[0109] In another embodiment, the first connecting portion 11 and the second connecting portion 21 are female connectors 40, and the third connecting portion 210 and the fourth connecting portion 310 are male connectors 30. The female connector 40 has an insertion space 41, and the sidewall surrounding the insertion space 41 has a first slot 42 communicating with the insertion space 41.

The second locking member 60 is detachably inserted through the first slot 42 and the second slot 31 to fix the second connector 20 and the second workpiece 300 through the second connecting portion 21 and the fourth connecting portion 310.

[0110] Please see Figure 1 , Figure 2 and Figure 9In some embodiments, the first workpiece 200 includes a first pipe 220, a third connecting portion 210 is disposed at one end of the first pipe 220, and the first connector 10 and the first pipe 220 are connected through the first connecting portion and the third connecting portion 210; and / or the second workpiece 300 includes a second pipe 320, a fourth connecting portion 310 is disposed at one end of the second pipe 320, and the second connector 20 and the second pipe 320 are connected through the second connecting portion and the fourth connecting portion 310; and / or the second workpiece 300 includes a heat exchanger 330, a fourth connecting portion 310 is disposed on the heat exchanger 330, and the second connector 20 and the heat exchanger 330 are connected through the second connecting portion and the fourth connecting portion 310.

[0111] Thus, by connecting the first pipe 220 and the second pipe 320 through the water valve 100, the flow rate of domestic water in the pipes can be controlled. By connecting the water valve 100 to the heat exchanger 330, the domestic water entering the heat exchanger 330 can be controlled, thereby improving the heat exchange efficiency of the heat exchanger 330.

[0112] Specifically, the first workpiece 200 can be the first pipe 220, which can be used to transport domestic water. The third connecting part 210 is provided at one end of the first pipe 220, and the first connector 10 and the first pipe 220 are connected through the first connecting part and the third connecting part 210.

[0113] The second workpiece 300 can be a second pipe 320, which can be used to transport domestic water. The fourth connecting part 310 is provided at one end of the second pipe 320, and the second connector 20 and the second pipe 320 are connected by the second connecting part and the fourth connecting part 310.

[0114] In some embodiments, the second workpiece 300 may be a heat exchanger 330, which may include, but is not limited to, a plate heat exchanger 330. The heat exchanger 330 is used to exchange the domestic water supplied to the heat exchanger 330 via the water valve 100 and the refrigerant supplied to the heat exchanger 330 for heat exchange. A fourth connecting part 310 is provided on the heat exchanger 330, and the second connector 20 and the heat exchanger 330 can be connected via the second connecting part and the fourth connecting part 310, thereby allowing the water valve 100 to be connected to the heat exchanger 330 and controlling the domestic water entering the heat exchanger 330.

[0115] Please refer to it again. Figure 3 In some embodiments, the second workpiece 300 includes a water tank 340, a fourth connecting part 310 is disposed on the water tank 340, and the water valve 100 and the water tank 340 are connected through the second connecting part 21 and the fourth connecting part 310.

[0116] Thus, by connecting the water valve 100 and the water tank 340, it is possible to control the flow of domestic water from the hydraulic module 1000 into the water tank 340 or to control the flow of domestic water from the water tank 340 into the hydraulic module 1000, thereby improving the stability of the hydraulic module 1000.

[0117] Specifically, the second workpiece 300 can be a water tank 340, which can be a domestic water tank 340, used to store and distribute domestic water in the hydraulic module 1000. A fourth connection part 310 is provided on the water tank 340, and the water valve 100 and the water tank 340 can be connected through the second connection part 21 and the fourth connection part 310, thereby allowing the water valve 100 to control the domestic water entering the water tank 340.

[0118] Please see Figure 3 In some embodiments, the hydraulic module 1000 includes an expansion tank 400, the second workpiece 300 includes a third pipe 350, one end of the third pipe 350 is connected to the expansion tank 400, and a fourth connection 310 is provided at the other end of the third pipe 350. The water valve 100 and the third pipe 350 are connected through the second connection 21 and the fourth connection 310.

[0119] Thus, by connecting the water valve 100 to the expansion tank 400, excess water in the hydraulic module 1000 can flow into the expansion tank 400 after passing through the water valve 100, thereby preventing the hydraulic module 1000 from being under excessive pressure to a certain extent.

[0120] Specifically, the hydraulic module 1000 includes an expansion tank 400, which can be used to maintain the pressure stability of the hydraulic module 1000. The second component 300 includes a third pipe 350, one end of which is connected to the expansion tank 400, and a fourth connection 310 is located at the other end of the third pipe 350. The water valve 100 and the third pipe 350 are connected through the second connection 21 and the fourth connection 310, thereby enabling the water valve 100 to control the domestic water entering the water tank 340.

[0121] For example, when the water temperature in the water tank 340 rises, the volume expands and the pressure increases. The excess water can flow into the expansion tank 400, thereby preventing the hydraulic module 1000 from being under excessive pressure to some extent.

[0122] In the above embodiments, the water tank 340 and the expansion tank 400 can be connected, thereby improving the stability of the hydraulic module 1000.

[0123] Optionally, the hydraulic module 1000 may include components such as a water pressure gauge and an air vent valve, and the second workpiece 300 includes a fourth pipe. One end of the fourth pipe is connected to the water pressure gauge and air vent valve, and a fourth connection part 310 is provided at the other end of the fourth pipe. The water valve 100 and the fourth pipe are connected through the second connection part and the fourth connection part 310.

[0124] The present invention provides a heating unit including the hydraulic module 1000 of any of the above embodiments.

[0125] Specifically, in one embodiment, the heating unit may include heat source equipment and heating terminals. The hydraulic module 1000 is the core component of the heating unit, organically combining the heat source equipment and heating terminals to realize the generation, transmission, and distribution of heat. Hot water generated by the heat source equipment can be stored in a water tank 340 within the hydraulic module 1000. The hot water in the water tank 340 can be delivered to each heating terminal, thereby providing heat to the entire heating unit. The heat source equipment may include, but is not limited to, an outdoor unit, a gas boiler, or a solar water heater. The heating terminals may include, but are not limited to, a domestic water tank 340, a zone one system, and a zone two system.

[0126] The outdoor unit may include a heat pump system, which heats cold water into hot water and distributes it through the water tank 340 of the hydraulic module 1000. A gas boiler uses the heat generated during gas combustion to heat cold water to form hot water. The hot water output from the gas boiler is distributed through the water tank 340 in the hydraulic module 1000. A solar water heater can be connected to the hydraulic module 1000 via pipes. The solar water heater directly heats water using solar energy, and the hot water is then distributed through the water tank 340 in the hydraulic module 1000.

[0127] In one example, the heating terminal can be a domestic water tank 340. The water tank 340 in the hydraulic module 1000 can deliver hot water to the coils within the domestic water tank 340. The hot water then transfers heat through the coils to the domestic water in the domestic water tank 340, raising its temperature. The domestic water tank 340 can be connected to water outlet valves 100 such as faucets and showerheads, allowing the heated domestic water to be supplied to users.

[0128] In one example, the heating terminal could be a zone system. The water tank 340 in the hydraulic module 1000 can deliver hot water to the zone system, which may include heaters suspended from the indoor ceiling, including but not limited to fan coil units (FCUs). The fan coil units can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0129] In one example, the heating terminal could be a zone two system. The water tank 340 in the hydraulic module 1000 can deliver hot water to the zone two system, which may include underfloor heating and / or radiators. Underfloor heating radiates heat from the hot water to the floor, while radiators radiate heat from the hot water into the room, thereby raising the temperature of the floor and the room.

[0130] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0131] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
