Description

Technical Field

[0001] This utility model relates to the field of water circuit valve accessories for wall-hung boilers, and in particular to a water circuit valve connecting element. Background Technology

[0002] Wall-hung boilers are dual-purpose boilers that provide both heating and domestic hot water. They feature built-in plate heat exchangers or other heat exchange structures (the term "plate heat exchanger" in this context does not preclude the possibility of using other heat exchange structures as substitutes), providing instant hot water. Wall-hung boiler systems are primarily used for heating and require connection to a hot water storage tank with an independent heat exchange tank.

[0003] Water valves are installed at the bottom of the casing of the wall-mounted boiler / combination boiler and the system boiler for connecting to the external water system. In order to achieve universal production molds for the main structure of the water valves in the combination boiler and the system boiler, reduce product models and specifications, and reduce production management costs, it is necessary to ensure that the water valves (inlet and outlet valves) can be used in the combination boiler with the plate heat exchanger integrated, and can also be used in the system boiler after the plate heat exchanger is removed.

[0004] However, when using a water valve with the plate heat exchanger removed in a system boiler, a connecting element is needed to connect the heating water interface and the domestic water interface on the water valve that were originally connected to the plate heat exchanger. Utility Model Content

[0005] The main objective of this invention is to provide a water circuit valve connecting element and a water circuit valve, so as to at least solve the above-mentioned technical problems existing in the prior art.

[0006] To achieve the above objectives, a first aspect of this utility model provides a water circuit valve connecting element for connecting a heating water interface and a domestic water interface on a water circuit valve. The water circuit valve connecting element includes: a coupling plate for connecting to the water circuit valve, the coupling plate having a coupling surface facing the water circuit valve when connected to the water circuit valve, a first inlet / outlet and a second inlet / outlet being provided on the coupling surface, the coupling plate also having a pipe surface facing away from the water circuit valve when connected to the water circuit valve, and a connecting pipe being provided on the pipe surface to connect the first inlet / outlet and the second inlet / outlet.

[0007] In one embodiment, a threaded post is provided on the coupling surface of the coupling plate, and the threaded post is located between the first inlet / outlet and the second inlet / outlet.

[0008] In one embodiment, the connecting pipe is welded to the coupling plate.

[0009] In one embodiment, a first welding hole and a second welding hole are provided on the pipeline surface for welding and connecting the two ends of the pipeline. The first welding hole is directly connected to the first inlet and outlet, and the second welding hole is directly connected to the second inlet and outlet.

[0010] In one possible implementation, the connecting pipe is an arc-shaped pipe.

[0011] In one embodiment, the connecting pipe is made of copper.

[0012] In one embodiment, a sealing flange is provided at the edge of the coupling surface of the coupling plate.

[0013] In one embodiment, the threaded post is positioned at the center between the first inlet / outlet and the second inlet / outlet; or, the threaded post is positioned off-center from the center line connecting the first inlet / outlet and the second inlet / outlet.

[0014] In a second aspect, this utility model provides a water valve, including a valve body and a water valve connecting element. The valve body is provided with a heating water interface and a domestic water interface. The water valve connecting element is used to connect the heating water interface and the domestic water interface. The first inlet and outlet and the second inlet and outlet are respectively connected to the heating water interface and the domestic water interface.

[0015] In one embodiment, a fixing hole is provided on the valve body between the heating water interface and the domestic water interface. When the water valve connecting element is assembled on the valve body, the fixing hole is aligned with the threaded hole on the threaded post, and the water valve connecting element is assembled on the valve body by fastening screws.

[0016] The water circuit valve of this utility model can be used in the water circuits of wall-mounted boilers, dual-purpose boilers and system boilers. The water circuit valve connecting element can connect the heating water interface and the domestic water interface on the water circuit valve, which were originally used to connect to the plate heat exchanger, in the water circuit of the system boiler. This realizes the commonality of the production mold of the water circuit valve in dual-purpose boilers and system boilers, reduces the number of product models and specifications, and lowers the production management cost.

[0026] The water valve 100 (wall-hung boiler inlet / outlet valve) in this utility model can be used in a dual-purpose boiler with the plate heat exchanger 200 integrated, or in a system boiler after the plate heat exchanger 200 has been removed. (Refer to...) Figure 1 When the water valve 100 is connected to the plate heat exchanger 200, the hot water inlet and outlet of the plate heat exchanger 200 are connected to the heating water interface 101 on the water valve 100, and the cold water inlet and outlet of the plate heat exchanger 200 are connected to the domestic water interface 102 on the water valve 100. Then, the plate heat exchanger 200 and the water valve 100 are connected and fixed by fastening screws 400 passing through the fixing holes 103 on the plate heat exchanger.

[0027] Reference Figures 2-4In order to enable the water valve 100 to be used in a wall-hung boiler system, this utility model provides a water valve connecting element 300 for connecting the heating water interface 101 and the domestic water interface 102 on the water valve 100. The water valve connecting element 300 includes: a coupling plate 301 for connecting with the water valve 100. The coupling plate 301 has a coupling surface 3011 facing the water valve 100 when connected with the water valve 100. A first inlet / outlet 302 and a second inlet / outlet 303 are provided on the coupling surface 3011. The coupling plate 301 also has a pipe surface 3012 facing away from the water valve 100 when connected with the water valve 100. A connecting pipe 308 is provided on the pipe surface 3012 to connect the first inlet / outlet 302 and the second inlet / outlet 303. The connecting pipe 308 is preferably an arc-shaped pipe, but other shapes are not excluded.

[0028] In the embodiments of this utility model, when the connecting pipe 308 is set as an arc-shaped pipe, the connecting pipe 308 is made of copper material, which enables the connecting pipe 308 to have stable physical and chemical properties. However, it is not excluded that other materials may be used to manufacture the connecting pipe 308.

[0029] In the embodiments of this utility model, certain requirements are placed on the structural stability and sealing performance of the coupling plate 301. Generally, hard metals such as brass, which are not easily rusted or deformed, are used. When the connecting pipe 308 is made of copper, the coupling plate 301 cannot be made of copper. Therefore, the connecting pipe 308 and the coupling plate 301 cannot be integrally formed and need to be connected and fixed. To improve production efficiency, welding is used to connect the connecting pipe 308 and the coupling plate 301. Specifically, refer to... Figure 2 , Figure 4 The pipe surface 3012 is provided with a first welding hole 305 and a second welding hole 306 for welding the two ends of the connecting pipe 308. The first welding hole 305 is directly connected to the first inlet / outlet 302, and the second welding hole 306 is directly connected to the second inlet / outlet 303. Both the first welding hole 305 and the second welding hole 306 protrude from the surface of the pipe surface 3012. Raising the position of the welding hole can reduce the probability of damaging the coupling plate 301 during welding, and the longer length of the connecting pipe 308 extending into the welding hole can improve the welding reliability and sealing. After the connecting pipe 308 and the coupling plate 301 are welded, the first inlet / outlet 302 and the second inlet / outlet 303 are connected. That is, after the water valve connecting element 300 is assembled on the water valve 100, the heating water interface 101 and the domestic water interface 102 on the water valve 100 can be connected.

[0030] Reference Figure 2 , Figures 4-7In the embodiments of this utility model, the heating water interface 101 and the domestic water interface 102 on the water valve 100 are generally arranged in parallel and protrude from the surface of the valve body to form a racetrack-shaped boss. A racetrack-shaped sealing flange 307 is provided on the edge of the coupling surface 3011 of the coupling plate 301 to fit the racetrack-shaped boss on the water valve 100 and form a sealed plug-in fit. The sealing flange 307 can also play a guiding role during assembly. A fixing hole 103 is provided on the valve body of the water valve 100 between the heating water interface 101 and the domestic water interface 102. A threaded post 304 is provided on the coupling surface 3011 of the coupling plate 301. The threaded post 304 is located between the first inlet / outlet 302 and the second inlet / outlet 303. When the water valve connecting element 300 is assembled on the water valve 100, the threaded post 304 can be inserted into the fixing hole 103, and the fixing hole 103 can be aligned with the threaded hole on the threaded post 304. The water valve connecting element 300 can be assembled and fixed on the water valve 100 by tightening the fastening screw 400 with the threaded hole on the threaded post 304.

[0031] Reference Figure 8 and Figure 9 The specific location of the threaded post 304 is set according to the location of the fixing hole 103 on the water valve 100, so as to ensure that the threaded post 304 can be inserted into the fixing hole 103 during assembly. Therefore, the threaded post 304 can be set as follows: Figure 9 The center position can also be set as follows: Figure 8 It is located slightly above the center of the middle.

[0032] Reference Figure 3 and Figure 4 In an embodiment of this utility model, a water circuit valve 100 for a wall-hung boiler system is also provided, including a valve body and a water circuit valve connecting element 300. The valve body is provided with a heating water interface 101 and a domestic water interface 102 originally used to connect to the plate heat exchanger 200. The water circuit valve connecting element 300 is used to replace the plate heat exchanger 200 in connecting the heating water interface 101 and the domestic water interface 102. The first inlet and outlet 302 and the second inlet and outlet 303 are respectively connected to the heating water interface 101 and the domestic water interface 102.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
