Description

Technical Field

[0001] The invention belongs to the technical field of water heater tank production, and in particular relates to a tool for plugging an interface of a water heater tank. Background Art

[0002] The water tank of a water heater is one of the common water storage devices, which includes an inner tank and an outer shell, as well as a heat-insulating material filled between the inner tank and the outer shell. In order to meet the water inlet and water outlet requirements of the water heater tank, it usually also includes a pipe joint connected to the inner tank and capable of passing through the outer shell. In order to meet the sealing requirements of the water heater tank and prevent it from being immersed in external gas or liquid, it usually also includes a transfer cover disposed between the outer shell and the pipe joint and connected to the two.

[0003] In the production process of the water heater tank, it is necessary to fill the space between the inner tank and the outer shell of the water heater tank with insulation material. When filling the insulation material, due to the structural limitation of the adapter cover, the insulation material will overflow from the gap between the adapter cover and the outer shell and between the adapter cover and the pipe joint, resulting in waste of insulation material. It can be seen that the overflow of insulation material from the gap between the adapter cover and the outer shell and between the adapter cover and the pipe joint is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In order to solve all or part of the above-mentioned problems, the purpose of the present invention is to provide a tool for sealing the interface of the water heater tank, so as to solve the problem of the thermal insulation material overflowing from the gap between the adapter cover and the outer shell and between the adapter cover and the pipe joint in the prior art, and to reduce the waste of thermal insulation material and reduce the production cost of the water heater tank.

[0005] The present invention provides a tool for sealing an interface of a water tank of a water heater, wherein the water tank of the water heater comprises an outer shell, an inner tank arranged in the outer shell, a pipe joint connected to the inner tank and capable of passing through the outer shell, and an adapter cover arranged between the outer shell and the pipe joint and connected to the two. The tool comprises: a tool body having a connecting end and a control end opposite thereto; a first clamping component arranged on the tool body; and a second clamping component arranged on the tool body; wherein the tool body is constructed so that when its connecting end is connected to the pipe joint, not only the first clamping component can press the adapter cover onto the pipe joint, but also the second clamping component can press the adapter cover onto the outer shell.

[0006] Furthermore, the second clamping component includes: a pressure cap, which is slidably mounted on the tool body; a nut, which is mounted on the tool body and cooperates with the external thread provided on the tool body through its internal thread, so that the nut can be rotated and push the pressure cap to move toward the direction close to the shell.

[0007] Furthermore, the pressure cap includes a barrel, an inner flange connected to the inner circumferential wall of the barrel and used to contact the tool body and the nut, and an outer flange connected to the outer circumferential wall of the barrel and capable of applying pressure to the adapter cover.

[0008] Furthermore, the tool also includes a sealing rubber ring which is sleeved on the barrel and abuts against an outer flange of the pressure cap close to the outer shell, and the pressure cap is made of solid metal material.

[0009] Furthermore, the pressure cap is made of polyurethane soft glue with a Shore hardness of 70-90HA.

[0010] Furthermore, the first clamping component comprises a clamping ring fixedly or detachably sleeved on the tool body.

[0011] Furthermore, the connection between the clamping ring and the tool body is a threaded connection.

[0012] Furthermore, the tool body includes a guide channel arranged therein, the guide channel includes an inlet for receiving a heating medium and an outlet for connecting to the pipe joint, and the tool also includes a tubular adapter arranged on the tool body and connected to the outlet.

[0013] Furthermore, it also includes a handle vertically arranged on the control end of the tool body.

[0014] Furthermore, the connection between the tool body and the pipe joint is a threaded connection.

[0015] Furthermore, the water tank of the water heater is a water tank of an air-energy water heater.

[0016] It can be seen from the above technical solution that the tool for sealing the interface of the water tank of the water heater of the present invention connects the connecting end of the tool body to the pipe joint by the operator operating the operating end of the tool body, so that the first pressing component presses the adapter cover on the pipe joint, and the second pressing component presses the adapter cover on the shell. When the adapter cover is pressed onto the pipe joint and the shell, if the insulation material is filled between the shell and the inner tank, the insulation material cannot overflow from the gap between the adapter cover and the pipe joint, and also cannot overflow from the gap between the adapter cover and the shell, thereby solving the problem of the insulation material overflowing from the gap between the adapter cover and the shell and between the adapter cover and the pipe joint, and reducing the waste of insulation material and the production cost of the water tank of the water heater.

[0021] The present invention will be further described below in conjunction with the accompanying drawings. Figure 1 A tool for plugging an interface of a water heater tank according to an embodiment of the present invention is shown; Figure 2 for Figure 1 The tool is shown in cross-section when in use. Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a tool 100 for plugging the interface of a water heater tank. The water heater tank is preferably a water tank of an air-energy water heater. The water heater tank includes a shell 210, an inner tank 220 disposed in the shell 210, and a pipe joint 230 connected to the inner tank 220 and capable of passing through the shell 210, and an adapter cover 240 disposed between the shell 210 and the pipe joint 230 and connected to the two. The tool 100 includes a tool body 10, a first clamping component 20 and a second clamping component 30. The tool body 10 has a connecting end and a control end opposite thereto. The first clamping component 20 and the second clamping component 30 are respectively disposed on the tool body 10. The tool body 10 is configured such that when its connecting end is connected to the pipe joint 230, not only the first clamping component 20 can clamp the adapter cover 240 on the pipe joint 230, but also the second clamping component 30 can clamp the adapter cover 240 on the shell 210. The operator manipulates the manipulation end of the tool body 10 to connect the connection end of the tool body 10 to the pipe joint 230, so that the first pressing component 20 presses the adapter cover 240 onto the pipe joint 230, and the second pressing component 30 presses the adapter cover 240 onto the shell 210. When the adapter cover 240 is pressed onto the pipe joint 230 and the shell 210, if the insulation material is filled between the shell 210 and the inner tank 220, the insulation material cannot overflow from the compressed gap between the adapter cover 240 and the pipe joint 230, and also cannot overflow from the gap between the adapter cover 240 and the shell 210, thereby solving the problem of the insulation material overflowing from the gap between the adapter cover 240 and the shell 210 and between the adapter cover 240 and the pipe joint 230, reducing the waste of insulation material, and reducing the production cost of the water tank of the water heater.

[0022] In this embodiment, the second clamping component 30 includes a pressing cap 32 and a nut 31. The pressing cap 32 is slidably mounted on the tool body 10. The nut 31 is mounted on the tool body 10 and cooperates with the external thread provided on the tool body 10 through its internal thread. The nut 31 can be rotated and push the pressing cap 32 to move toward the direction close to the outer shell 210 to ensure that the pressing cap 32 presses the adapter cover 240 on the outer shell 210 and achieves the purpose of adjustable clamping force at the same time. At the same time, the nut 31 cooperates with the internal thread and external thread of the tool body 10 to achieve its detachable connection. By replacing the pressing caps 32 of different sizes, the tool 100 can be used to block the interfaces of water heater tanks of different models, thereby expanding its application scenarios.

[0023] Preferably, the pressure cap 32 includes a barrel 32b, an inner flange 32c and an outer flange 32a. The inner flange 32c is connected to the inner peripheral wall of the barrel 32b and is used to contact the tool body 10 and the nut 31. The outer flange 32a is connected to the outer peripheral wall of the barrel 32b and can apply pressure to the adapter cover 240. Among them, the outer flange 32a can increase the contact area between the pressure cap 32 and the outer shell 210, and further improve the sealing effect between the two. The inner flange 32c can reduce the contact area between the pressure cap 32 and the tool body 10, and reduce the resistance generated when the pressure cap 32 slides on the tool body 10.

[0024] In this embodiment, in order to improve the sealing effect of the gap between the pressure cap 32 and the shell 210, the following two methods can be selected. The first method is that the tool 100 also includes a sealing rubber ring 40 that is sleeved on the barrel 32b and abuts against the outer flange 32a of the pressure cap 32 close to the shell 210, wherein the pressure cap 32 is made of a solid metal material. The solid metal material can be selected from materials such as copper, stainless steel or aluminum. Because stainless steel has the advantages of low cost and easy processing, stainless steel is selected as the preferred material. The sealing rubber ring 40 can further improve the sealing effect. The second method is that the pressure cap 32 is made of polyurethane soft glue with a Shore hardness of 70-90HA. Since the water tank shell 210 mostly adopts a thin-walled structure, it is easy to deform after being stressed and the outer surface is coated with an anti-corrosion coating. The polyurethane soft glue is soft and elastic, which can prevent the shell 210 from being deformed due to excessive pressure or the shell 210 from being scratched during installation and damaging the coating.

[0025] In the present embodiment, the first clamping component 20 includes a clamping ring fixedly or detachably mounted on the tool body 10. When the connecting portion of the tool body 10 is connected to the pipe joint 230, the clamping ring can press the adapter cover 240 toward the pipe joint 230 to prevent the insulation material from flowing out of the gap between the adapter cover 240 and the pipe joint 230. The first clamping component 20 and the tool body 10 are preferably detachably connected, especially threadedly connected. Therefore, by selecting clamping rings of different thicknesses or arranging the clamping rings at different positions on the tool body 10, the tool 100 can be used to seal the interfaces of water heater tanks of different models, thereby expanding its application scenarios.

[0026] In this embodiment, the tool body 10 includes a flow guide channel disposed therein, the flow guide channel includes an inlet for receiving a heating medium and an outlet for connecting a pipe joint 230, and the tool 100 also includes a tubular adapter 50 disposed on the tool body 10 and connected to its outlet. When the heat-insulating material between the inner liner 220 and the outer shell 210 is a foaming material, its foaming quality is affected by the temperature of the inner liner 220 and the outer shell 210. In winter, foaming defects may occur due to the excessively low temperature of the inner liner 220. At this time, the outlet of the heating device may be connected to the tubular adapter 50, and the heating medium may be introduced into the inner liner 220 through the outlet of the pipe joint 230 through the inlet of the flow guide channel, so as to heat the inner liner 220, reduce the occurrence of foaming defects, and improve the qualified rate of foaming.

[0027] In this embodiment, the tool 100 further comprises a handle 60 vertically disposed on the manipulation end of the tool body 10. The handle 60 helps the operator to easily manipulate the tool body 10 so as to connect its connection end with the pipe joint 230.

[0028] In this embodiment, the connection method between the tool body 10 and the pipe joint 230 can be selected as a snap connection, an interference fit or a threaded connection, etc., but it is recommended to preferably use a threaded connection because the threaded connection has a better sealing effect.

[0029] In summary, the water heater tank of each embodiment of the present invention can solve the problem of thermal insulation material overflowing from the gap between the pipe joint 230 and the outer shell 210 and between the pipe joint 230 and the inner tank 220, and save costs.
