Description

Technical Field

[0001] The utility model relates to the technical field of heating integrated water channels, in particular to an integrated water channel module. Background Art

[0002] The integrated water channel module is usually installed in the wall-mounted boiler system to achieve the connectivity and switching of the pipelines. The integrated water channel module usually includes an inlet valve, an outlet valve and a heat exchanger connected between the inlet valve and the outlet valve. The outlet valve and the inlet valve are usually connected to the heat exchanger by screws. After integration and assembly by the manufacturer, they are shipped to the client. However, during transportation, the integrated water channel module will be affected by external forces such as impact and bumps, causing the positions of the various interfaces of the inlet valve and the outlet valve to shift, making the various interfaces incompatible with the tools used by the client to install the water pipes. In severe cases, it may even cause the screws to loosen, posing a risk of leakage.

[0003] Therefore, there is an urgent need to provide an integrated waterway module to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0040] This embodiment provides an integrated water channel module that can be installed in a wall-mounted boiler system and is mainly used to achieve the connection and switching of pipes. Figure 1 As shown, the integrated water channel module includes a water outlet valve 10, a water inlet valve 20 and a heat exchanger 30. The water outlet valve 10 and the water inlet valve 20 are respectively fixed at the two ends of the heat exchanger 30 by screws, and the water outlet valve 10 and the water inlet valve 20 are located on the same side of the heat exchanger 30. The integrated water channel module also includes a limit plate 80, which is fixedly connected to the bottom of the water outlet valve 10 and the water inlet valve 20.

[0041] Specifically, if Figure 1 and Figure 2 As shown, the bottom of the valve body 11 of the water outlet valve 10 is provided with a second valve port 112 and a fifth valve port 116, and the bottom of the water inlet valve 20 is provided with a sixth valve port 22. The second valve port 112, the fifth valve port 116, and the sixth valve port 22 are oriented in the same direction and are all provided with a connector 90. The connector 90 is used to connect to the external pipeline. The limiting plate 80 is provided with a limiting hole 81 with a shape that is adapted for each connector 90 to pass through. During installation, the limiting plate 80 is sleeved on the outside of each connector 90 and then fixedly connected to the water outlet valve 10 and the water inlet valve 20. In this way, the cooperation between the connector 90 and the limiting hole 81 can limit the water inlet valve 20 and the water outlet valve 10, thereby preventing the interface of the water inlet valve 20 and the water outlet valve 10 from being offset due to external forces during transportation, thereby preventing the screws between the water inlet valve 20, the water outlet valve 10 and the heat exchanger 30 from loosening, and reducing the risk of leakage.

[0042] Furthermore, the limiting plate 80 is connected to the bottom of the outlet valve 10 and the inlet valve 20 respectively by fasteners, thereby ensuring the stability of the connection between the limiting plate 80 and the outlet valve 10 and the inlet valve 20, and further improving the limiting effect of the inlet valve 20 and the outlet valve 10 during transportation. The fasteners can be screws.

[0043] In this embodiment, the valve bodies 11 of the water inlet valve 20 and the water outlet valve 10 are both plastic, while the joints 90 are metal, specifically copper. Using engineering plastics to manufacture the water inlet valve 20 and the water outlet valve 10 significantly reduces product weight and production costs compared to all-metal materials. Furthermore, metal joints 90 offer better torsional resistance than plastic.

[0044] In an optional embodiment, if Figure 3 and Figure 4As shown, the connector 90 specifically includes a rotating portion 91, an anti-rotation portion 92, and an external connection portion 93. The anti-rotation portion 92 is connected between the rotating portion 91 and the external connection portion 93. The rotating portion 91 has a circular cross-section and is rotatably connected to the corresponding valve port. The anti-rotation portion 92 is rotationally limited in cooperation with the corresponding limiting hole 81 to limit the rotation of the connector 90 during transportation, thus effectively limiting the position. The external connection portion 93 is used to connect to an external pipeline. In the prior art, the connector 90 is rotationally limited in cooperation with the corresponding valve port through the anti-rotation portion 92. However, the torque that each valve body 11 made of engineering plastic can withstand is small. Excessive torque during later installation may damage the water inlet valve 20 and the water outlet valve 10. By setting the above-mentioned type of joint 90, the joint 90 can be rotatably matched with the valve port through the rotating part 91, and the anti-rotation part 92 is rotationally limited and matched with the limiting hole 81, and the torque force point is moved to the joint 90 and the limiting plate 80. The joint 90 is a copper part, so it can withstand a large torque, avoiding damage to the water inlet valve 20 and the water outlet valve 10.

[0045] In another optional embodiment, the clearance between the connector 90 and the valve port is greater than the clearance between the connector 90 and the stopper hole 81. With this arrangement, when the connector 90 is rotated and deflected by torsional force, the force point can be shifted to the connector 90 and the stopper plate 80, thus preventing damage to the water inlet valve 20 and the water outlet valve 10.

[0046] Optionally, in order to achieve the rotation limiting effect of the anti-rotation part 92 and the limiting hole 81, the cross-section of the anti-rotation part 92 can be a regular polygon, such as an equilateral triangle, a square, a regular pentagon or a regular hexagon, etc. Of course, it can also be an irregular shape, and the shape of the limiting hole 81 can be adapted to the anti-rotation part 92.

[0047] Preferably, in this embodiment, Figure 2 and Figure 3 As shown, the cross-sections of the anti-rotation portion 92 and the limiting hole 81 are both regular hexagons. This arrangement facilitates processing and reduces processing costs.

[0048] In an optional embodiment, if Figure 3 As shown, a chamfer 94 is formed between each adjacent side surface of the anti-rotation portion 92. By providing the chamfer 94, the anti-rotation portion 92 can serve as a primary limit structure. That is, during transportation, the cooperation between the anti-rotation portion 92 and the limit hole 81 can limit the rotation of the connector 90, playing an effective limit role. After arriving at the customer's end, the connector 90 needs to be connected to an external pipeline. By providing the chamfer 94, the anti-rotation portion 92 will lose its function after being subjected to a certain torque. Therefore, only a slight force is required to twist the connector 90, and the anti-rotation portion 92 can rotate within the limit hole 81, completing the pipeline installation operation.

[0049] In an optional embodiment, in combination Figure 2 and Figure 3The outer circumference of the rotating portion 91 is provided with a first slot 911, and the circumferences of the valve port 2 112, the valve port 5 116, and the valve port 6 22 are each provided with two first through holes 118 that cooperate with the first slots 911. The first pin 119 passes through the first through hole 118 and is inserted into the first slot 911, so that the connector 90 can be axially fixedly assembled in the corresponding valve port. By pulling the first pin 119 out of the first slot 911 and the first through hole 118, the connector 90 can be disconnected from the valve port. Through the above arrangement, the connector 90 can be quickly installed and removed, and the operation is convenient. The valve bodies 11 of the water inlet valve 20 and the water outlet valve 10 are both plastic parts, and it is not easy to process threads on plastic parts. Even if they are processed, it is difficult to control the position when rotating and installing the connector 90, and the plastic parts are easily damaged. Therefore, the above technical solution can be used to solve the fixing problem.

[0050] Specifically, if Figure 4 As shown, the outlet valve 10 includes a valve body 11, a three-way valve core 12, and a drive member 13. The valve body 11 is further provided with a valve port 111 and a valve port 3 113 connected to the heat exchanger 30. The valve body 11 also has a valve cavity 101. The three-way valve core 12 is disposed within the valve cavity 101. The drive member 13 is disposed outside the valve body 11 and connected to the three-way valve core 12. The drive member 13 can be a synchronous motor or a stepper motor and can drive the three-way valve core 12 to move along its axial direction so that the valve port 111 can selectively connect to the valve port 2 112 or the valve port 3 113. The valve port 111 is connected to the heat source through a pipeline for the inflow of hot water; the valve port 2 112 is connected to the heating pipeline for the outflow of hot water to achieve heating.

[0051] like Figure 4 and Figure 7 As shown, the valve body 11 is further provided with a valve port seven 117, which is arranged side by side with the valve port three 113. The water inlet valve 20 is provided with a valve port eight 23 and a valve port nine 24. The valve port three 113 of the water outlet valve 10 is connected to the interface one 31 of the heat exchanger 30, the valve port seven 117 is connected to the interface two 32 of the heat exchanger 30, the valve port eight 23 of the water inlet valve 20 is connected to the interface three 33 of the heat exchanger 30, and the valve port nine 24 is connected to the interface four 34 of the heat exchanger 30. There are hot water channels and cold water channels in the heat exchanger 30. The interface one 31 and the interface three 33 are connected to the hot water channel, and the interface two 32 and the interface four 34 are connected to the cold water channel. The hot water flowing through the hot water channel can exchange heat with the cold water flowing through the cold water channel. Valve port five 116 is connected to valve port seven 117. Valve port five 116 is the outlet for domestic hot water. Hot water in the cold water channel flows through valve port seven 117 to valve port five 116 for user use. Valve port six 22 is connected to valve port nine 24. Valve port six 22 is connected to an external water source to supply water to the cold water channel. The water inlet valve 20 also has valve port ten 25, which is connected to valve port eight 23 and connected to a water pump. The water pump transports the medium back to the heat source, forming a medium circulation system.

[0052] In the heating state, valve port 1 11 is connected to valve port 2 112 and is blocked from valve port 3 113. The hot water flowing in from valve port 1 111 flows through valve port 2 112 to the heating pipeline and is then transported back to the heat source through the water pump, forming a medium circulation; in the bathroom state, valve port 1 11 is connected to valve port 3 113 and is blocked from valve port 2 112. The hot water flowing in from valve port 1 111 flows through valve port 3 113 to the hot water channel of the heat exchanger 30, and then flows through valve port 8 23 of the water inlet valve 20 to the water pump at valve port 10 25. The water pump transports the medium back to the heat source, forming a medium circulation. At the same time, external cold water flows from valve port 6 22 to valve port 9 24, and then flows into the cold water channel of the heat exchanger 30. The cold water in the cold water channel exchanges heat with the hot water in the hot water channel, and then flows out through valve port 7 117 to valve port 5 116, and then flows into the bathroom pipeline to supply water to the bathroom for user use. In this embodiment, the heat exchanger 30 is a plate heat exchanger. Of course, in other embodiments, the heat exchanger 30 is not limited to a plate heat exchanger.

[0053] Further, if Figure 5 and Figure 6 As shown, the valve body 11 of the water outlet valve 10 is further provided with a bypass pipe 114 and a bypass flow channel 115. In the heating state, the bypass pipe 114 is connected to the valve port 2 112, and the bypass pipe 114 has an outlet 1 1141 and an outlet 2 1142. The outlet 1 1141 is provided at the axial end of the bypass pipe 114, and the outlet 2 1142 is provided on the circumferential side wall of the bypass pipe 114; Figure 9 As shown, the outlet 1141 can be connected to the valve port 21 of the water inlet valve 20 through the external pipeline 40, or, as shown in FIG. Figure 5 As shown, outlet 1141 and valve port 4 21 are both sealed by a plug 60; one end of the bypass channel 115 is connected to outlet 2 1142, and the other end is connected to valve port 3 113 through the valve chamber 101. A bypass valve 50 is provided in the bypass pipe 114. The bypass valve 50 is used to selectively connect valve port 2 112 to the external pipeline 40 or the bypass channel 115. The bypass valve 50 can be a one-way valve, which is used to unidirectionally connect valve port 2 112 and bypass pipe 114 to prevent water backflow.

[0054] The integrated water channel module provided in this embodiment is in a heating state, such as Figure 9 and Figure 10As shown, when external pressure relief is required, an external pipeline 40 is installed at the outlet 1141 of the bypass pipe 114 to communicate with the valve port 4 21 of the water inlet valve 20. When the medium pressure in the pipeline is greater than the pressure set by the bypass valve 50, the bypass valve 50 opens, the valve port 2 112 is directly connected to the external pipeline 40, and at the same time is cut off from the bypass flow channel 115. The medium in the bypass pipe 114 can flow into the valve port 4 21 of the water inlet valve 20 through the external pipeline 40, and then flow back to the heat source through the water pump at the valve port 10 25; Figure 5 and Figure 6 As shown, when internal pressure relief is required, the external pipe 40 is directly removed and the outlet 1 141 and valve port 4 21 are sealed with a plug 60. When the bypass valve 50 is opened, valve port 2 112 is directly connected to the bypass flow channel 115. The medium in the bypass pipe 114 can flow to the valve cavity 101 through the bypass flow channel 115, then flow into the hot water channel of the heat exchanger 30 through valve port 3 113, and then flow through valve port 8 23 of the water inlet valve 20 to the water pump at valve port 10 25 to transport the medium back to the heat source. Therefore, this integrated water channel module, whether it is an external bypass or an internal bypass, can be implemented in the same water outlet valve 10, and can be quickly switched according to customer needs. The product has strong applicability, is easy to prepare, has high production efficiency, is convenient and fast to switch, and is low in cost.

[0055] That is, when a customer requires an external bypass, an external pipe 40 is installed between the outlet 1141 of the bypass pipe 114 and the valve port 4 21 of the water inlet valve 20. When a customer requires an internal bypass, the external pipe 40 is simply replaced with a plug 60, and both the outlet 1141 and the valve port 4 21 are sealed by the plug 60. Therefore, this integrated waterway module can switch the bypass flow channel 115 simply by replacing some parts. Compared to the prior art, there is no need to replace the water outlet valve 10 and the water inlet valve 20, nor is there any need to perform any structural changes such as drilling holes in the valve body 11 and the water inlet valve 20. This product has strong applicability, low cost, quick changeover, and high efficiency when switching between bypass modes for the entire unit.

[0056] In an optional embodiment, if Figure 5 and Figure 6 As shown, to achieve a removable connection of the plug 60, a second slot 61 is provided on the outer periphery of the plug 60. Two second through-holes 1111 are provided around the periphery of both the outlet 1141 and the valve port 21, which mate with the second slots 61. A second pin 70 passes through the second through-holes 1111 and is inserted into the second slot 61, thereby installing the plug 60 at the outlet 1141 of the bypass pipe 114 and the valve port 21 of the water inlet valve 20. The plug 60 can be disconnected from the bypass pipe 114 by removing the second pin 70 from the second slot 61 and the second through-holes 1111. This arrangement allows for quick installation and removal of the plug 60, making it easy to operate.

[0057] It should be noted that, in an optional embodiment, the external pipeline 40 can also be detachably connected to the outlet 1141 of the bypass pipe 114 and the valve port 21 of the water inlet valve 20 through the above-mentioned pin form, and the settings of its second through hole 1111 and the second slot 61 are exactly the same as the above content, which will not be repeated here.

[0058] In an optional embodiment, the bypass pipe 114, the bypass flow channel 115 and the valve body 11 are integrally formed. This arrangement can reduce production costs, improve structural stability, and facilitate production.

[0059] like Figure 5 and Figure 6 As shown, the axis of valve port 112 coincides with the axis of valve cavity 101, and the axis of bypass pipe 114 is perpendicular to the axis of valve port 111. The axis of valve port 111 is perpendicular to the axis of valve port 112, and also perpendicular to the axis of bypass pipe 114. In other words, the axes of valve port 111, valve port 112, and bypass pipe 114 are perpendicular to each other. By properly positioning these three, pipeline connections can be facilitated, facilitating a rational pipeline layout.

[0060] In an optional embodiment, if Figure 5 and Figure 6 As shown, the axis of the bypass flow channel 115 is tilted relative to the axis of the bypass pipe 114. The tilted bypass flow channel 115 can reduce the overall volume of the valve body 11.

[0061] In an optional embodiment, if Figure 10 and Figure 11 As shown, the external pipeline 40 includes a tube body 41 and a joint portion 42 connected to one end of the tube body 41 near the bypass pipe 114. The joint portion 42 is inserted into the bypass pipe 114 and is sealed with the inner wall of the bypass pipe 114. The bypass valve 50 includes a valve seat 51, a sealing valve core 52 axially movably disposed in the valve seat 51, and a return spring (not shown). The valve seat 51 is provided with a water hole connected to the water inlet of the bypass pipe 114. The sealing valve core 52 can seal and close the water hole. One end of the return spring abuts the sealing valve core 52, and the other end abuts the valve seat 51. The outer wall of one end of the valve seat 51 is tightly fitted with the inner wall of the bypass pipe 114, and the other end is inserted into the joint portion 42 and is sealed with the inner wall of the joint portion 42.

[0062] During external pressure relief, when the medium pressure in the pipeline is greater than the pressure set by the bypass valve 50, the force of the medium pushes the sealing valve core 52 to the left and compresses the reset spring. At this time, the water hole is opened, allowing the medium to flow into the valve seat 51 through the water hole. Since the outer wall of the valve seat 51 is sealed with the inner wall of the joint part 42, a closed channel is formed in the valve seat 51 and the joint part 42, and the medium will flow directly into the tube body 41 through the closed channel. When the force of the medium is less than the elastic force of the reset spring, the reset spring will drive the sealing valve core 52 to reset. Therefore, by sealing the outer wall of the valve seat 51 with the inner wall of the joint part 42, when the sealing valve core 52 is opened, the valve port 2 112 can be connected to the external pipeline 40 and cut off from the bypass flow channel 115. During internal pressure relief, as Figure 6 As shown, the plug 60 seals the outlet 1141, and the plug 60 is spaced apart from the valve seat 51. Therefore, when the sealing valve core 52 is opened, the medium can flow into the valve seat 51 through the water hole, and then flow into the bypass channel 115 through the gap between the valve seat 51 and the plug 60.
