Description

Technical Field

[0001] The utility model relates to the technical field of valve components, in particular to a temperature sensor installation structure and a water outlet valve. Background Art

[0002] A gas-fired wall-mounted heating boiler (referred to as a wall-mounted boiler) uses natural gas, liquefied petroleum gas, or manufactured coal gas as its energy source, generating heat through combustion to provide home heating and domestic water. The outlet valve is an essential component of the wall-mounted boiler, serving as a diversion mechanism. Water from the boiler's combustion chamber flows through the outlet valve into the heating system, providing heating for the user. Water from the combustion chamber can also flow through the outlet valve into the domestic water line, providing hot water for use in areas such as the bathroom and kitchen.

[0003] In the related art, the bathroom outlet of the water outlet valve is usually connected to a metal joint, one end of which is plugged into the bathroom outlet, and the other end is provided with a threaded structure to connect to the domestic water pipeline to achieve fluid communication. In order to prevent the hot water flowing out of the bathroom outlet of the water outlet valve from being too hot, a temperature sensor is usually provided on the water outlet valve. The temperature sensor is used to detect the water temperature at the bathroom outlet so that the regulating component can adjust the flow rate of cold water in time according to the signal fed back by the temperature sensor. However, the installation position of the temperature sensor becomes a problem. It should be installed as close to the water outlet of the metal joint as possible to improve the accuracy of the detection result. If a hole is drilled near the water outlet of the metal joint, the threaded structure on the metal joint will be damaged, thereby affecting the stable connection between the metal joint and the water pipeline and affecting the safety of the water outlet valve.

[0054] Figure 1 A schematic structural diagram of the water outlet valve provided in this embodiment is shown at one viewing angle. Figure 2 A schematic cross-sectional structural diagram of the water outlet valve provided in this embodiment is shown. Figure 3 Shown Figure 2 Schematic diagram of the local structure. Figure 4 FIG. 1 shows a structural schematic diagram of the valve body 100 of the water outlet valve provided in this embodiment. Figure 5 FIG. 2 shows a schematic structural diagram of the connection joint 2 provided in this embodiment. Figure 1-Figure 5As shown, this embodiment provides a temperature sensor mounting structure, which includes a mounting portion 1, a connecting joint 2 and a temperature detecting component 3. The mounting portion 1 has a fluid channel for fluid to pass through, and a first mounting hole 11 connected to the fluid channel is provided on the side wall of the mounting portion 1; the connecting joint 2 is partially sealed and inserted into the fluid channel, and the part of the connecting joint 2 extending out of the fluid channel is used to connect to an external pipeline, and a second mounting hole 211 corresponding to the first mounting hole 11 is provided on the side wall of the connecting joint 2; the detection end 31 of the temperature detecting component 3 passes through the first mounting hole 11 and the second mounting hole 211 in sequence and extends into the inner hole of the connecting joint 2 for detecting the fluid temperature therein, and the temperature detecting component 3 is sealed and assembled with the mounting portion 1 and / or the temperature detecting component 3 and the connecting joint 2.

[0055] It should be explained that the temperature sensor mounting structure provided in this embodiment is mainly used on the water outlet valve, the mounting portion 1 is formed on the valve body 100, and the fluid channel on the mounting portion 1 forms a part of the bathroom channel 101 in the valve body 100.

[0056] Figure 6 The structure diagram of the water outlet valve provided in this embodiment is shown in another perspective. Figure 1 and Figure 6 Briefly describe the specific structure and working principle of the water outlet valve. Figure 1 and Figure 6 As shown, this embodiment also provides a water outlet valve, which is mainly used in the water system of a wall-mounted boiler to provide users with domestic water and meet their heating needs. Specifically, the water outlet valve includes a valve body 100, which has a three-way valve cavity, a bathroom channel 101, a heating channel 102, a heat exchange water inlet channel 103, and a heat exchange water outlet channel 104. The inlet of the three-way valve cavity is connected to the combustion chamber, and the three-way valve cavity can selectively connect to the heating channel 102 or the heat exchange water inlet channel 103. The heat exchange water inlet channel 103 is connected to the inlet of the heat exchange channel of the heat exchange structure, and the heat exchange water outlet channel 104 is connected to the water supply channel of the heat exchange structure. The heat exchange water outlet channel 104 is also connected to the bathroom channel 101. During use, when the three-way valve chamber is connected to the heating channel 102, the hot water heated by the combustion chamber can flow into the heating system through the three-way valve chamber and the heating channel 102 to meet the user's heating needs; when the three-way valve chamber is connected to the heat exchange water inlet channel 103, the hot water heated by the combustion chamber can flow into the heat exchange channel of the heat exchange structure through the three-way valve chamber and the heat exchange water inlet channel 103, and exchange heat with the water in the water supply channel of the heat exchange structure. After heat exchange, the water in the water supply channel can flow out to the heat exchange water outlet channel 104, and then flow from the bathroom channel 101 to the bathroom system to provide domestic water for users.

[0057] The heating system specifically refers to heat dissipation components such as radiators, floor heating pipes, or fan coil units. Water heated in the combustion chamber is pumped through a water outlet valve to these heat dissipation components, dissipating heat into the indoor air. This heat is then dissipated, thereby raising the indoor ambient temperature to meet the user's heating needs. The bathroom system specifically refers to water-using devices for showering, washing, and other operations. Therefore, both heating and bathroom systems are relatively mature technologies in this field, and their specific structures will not be detailed in this embodiment.

[0058] However, in the related art, the temperature of the water flowing out from the outlet of the bathroom channel can only be adjusted by the heat exchange efficiency of the heat exchange structure and the initial temperature of the water flowing into the heat exchange structure, resulting in a higher temperature of the water flowing out from the outlet of the bathroom channel of the water outlet valve, affecting the user's water experience.

[0059] In order to solve the above problems, in this embodiment, the water outlet valve also includes an adjusting component 200, and the valve body 100 also has a cold water flow channel 105 connected to the bathroom channel 101. The cold water flow channel 105 is connected to an external water source. The cold water flowing into the cold water flow channel 105 and the hot water flowing into the heat exchange outlet flow channel 104 can flow out from the outlet of the bathroom channel 101 after mixing; the adjusting component 200 is configured to adjust the flow rate of cold water in the cold water flow channel 105 to avoid the temperature of the water flowing out of the bathroom channel 101 being too high, affecting the user experience.

[0060] It should be noted that this embodiment does not limit the specific structure of the regulating assembly 200. Any regulating assembly in the prior art capable of regulating the flow of cold water into the cold water flow channel 105 is within the scope of protection of this embodiment. Furthermore, this embodiment does not limit the three-way switching method of the three-way valve chamber. Any method in the prior art capable of achieving three-way switching of the three-way valve chamber so that the three-way valve chamber can selectively connect to the heating channel 102 or the heat exchange water inlet flow channel 103 is within the scope of protection of this embodiment.

[0061] It should be explained that the connection joint 2 of the temperature sensor mounting structure provided in this embodiment is used to connect the bathroom channel 101 and the bathroom system to supply water to the bathroom system; the temperature detection component 3 is used to detect the temperature of the fully mixed mixed water in the bathroom channel 101, so that the adjustment component 200 can accurately adjust the flow rate of cold water in the cold water flow channel 105 according to the temperature signal fed back by the temperature detection component 3, thereby ensuring that water of appropriate temperature flows out of the bathroom channel 101 to meet the user's usage needs. Of course, in other embodiments, the temperature sensor mounting structure can also be used in other valve structures (such as water inlet valves, etc.) to be installed in the flow channel where fluid temperature detection is required, and the above-mentioned effects can also be achieved.

[0062] In this embodiment, by respectively providing corresponding first mounting holes 11 and second mounting holes 211 on the mounting portion 1 and the connecting joint 2, on the one hand, a suitable mounting position can be provided for the installation of the temperature detecting component 3 to ensure that it can be stably installed. On the other hand, the opening position of the second mounting hole 211 is provided at the part where the connecting joint 2 extends into the mounting portion 1, which can avoid the position where the connecting joint 2 is connected to the external pipeline, thereby ensuring a stable connection between the connecting joint 2 and the external pipeline; in addition, the connecting joint 2 is sealed and plugged into the mounting portion 1, and the temperature detecting component 3 and the mounting portion 1 and / or the temperature detecting component 3 and the connecting joint 2 are sealed and assembled, thereby ensuring the sealing of the connection parts between the mounting portion 1, the connecting joint 2 and the temperature detecting component 3, reducing the possibility of leakage at each connection part, and ensuring the safety of the entire water outlet valve.

[0063] To achieve a sealed assembly between the temperature sensing member 3 and the mounting portion 1 and / or between the temperature sensing member 3 and the connecting joint 2, in this embodiment, the temperature sensor mounting structure further includes a first sealing member (not shown) disposed between the sensing end 31 and the first mounting hole 11 and / or between the sensing end 31 and the second mounting hole 211. The first sealing member is a rubber sealing ring, which facilitates installation, provides a good sealing effect, and is relatively low in cost.

[0064] like Figure 3 As shown, to achieve a sealed connection between the connecting joint 2 and the mounting portion 1, the temperature sensor mounting structure further includes a second sealing member 4. The second sealing member 4 is located between the mounting portion 1 and the connecting joint 2, thereby achieving a sealed connection between the connecting joint 2 and the mounting portion 1 and preventing water in the bathroom passage 101 from leaking through the gap between the connecting joint 2 and the mounting portion 1. In this embodiment, the second sealing member 4 is a rubber sealing ring, which is easy to install, has a good sealing effect, and is relatively low in cost.

[0065] Figure 7 FIG. 2 shows a cross-sectional structural diagram of the connection joint 2 provided in this embodiment. Figure 7 Combined with Figure 3 、 Figure 5 As shown, the connecting joint 2 includes a plug-in portion 21 and an external portion 22 connected to each other. The plug-in portion 21 is sealed and plugged into the fluid channel. The second mounting hole 211 is provided on the plug-in portion 21. The outer wall of the external portion 22 is provided with a connection structure connected to an external pipeline. Among them, the second sealing member 4 is provided between the plug-in portion 21 and the mounting portion 1. When connecting, the second sealing member 4 can be first sleeved on the plug-in portion 21, and then the plug-in portion 21 of the connecting joint 2 can be inserted into the fluid channel of the mounting portion 1. The second sealing member 4 not only seals the connecting joint 2 and the mounting portion 1, but also has elastic force. Its two sides can be tightly pressed against the connecting joint 2 and the mounting portion 1, thereby ensuring a stable connection between the connecting joint 2 and the mounting portion 1.

[0066] Optionally, the connection structure on the external connection part 22 is an external thread, that is, the external connection part 22 is connected to the external pipeline by thread, which is convenient for disassembly and assembly, and the connection is stable.

[0067] To ensure stable installation of the second seal 4, in this embodiment, a mounting groove 212 is provided on the outer wall of the connector 2 (specifically, the plug portion 21). The mounting groove 212 is used to mount the second seal 4, preventing it from shifting or falling off during use and ensuring accurate positioning during installation. Of course, in other embodiments, the mounting groove 212 can also be provided on the inner wall of the mounting portion 1 to achieve the same effect.

[0068] like Figure 3 and Figure 7 As shown, the plug-in portion 21 is a stepped structure, and a limiting step 1011 is protruded inwardly on the inner wall of the fluid channel. The step surface 213 of the plug-in portion 21 can abut against the limiting step 1011 to limit the insertion depth of the connecting joint 2 in the fluid channel, thereby avoiding the plug-in depth of the connecting joint 2 being too deep, resulting in the length of the connecting joint 2 exposed in the fluid channel being too short, affecting the stability of its connection with the external pipeline, and at the same time, it can avoid the plug-in depth of the connecting joint 2 being too shallow, affecting the stability of the connection between the plug-in portion 21 and the mounting portion 1.

[0069] Continue as Figure 3 As shown, in some embodiments, the second sealing member 4 is located upstream of the temperature detection member 3 in the direction of fluid flow, and a first sealing member is provided between the detection end 31 and the second mounting hole 211. This arrangement prevents fluid in the bathroom passage 101 from leaking through the gap between the connecting joint 2 and the mounting portion 1, thereby ensuring the safety of the entire water outlet valve. In this example, a first sealing member can also be provided between the detection end 31 and the first mounting hole 11.

[0070] In other embodiments, the second sealing member 4 is located downstream of the temperature detecting member 3 along the fluid flow direction. In this case, the first sealing member can be provided between the detecting end 31 and the first mounting hole 11, or between the detecting end 31 and the second mounting hole 211, or between the detecting end 31 and the first mounting hole 11 and between the detecting end 31 and the second mounting hole 211. All of the above arrangements can prevent the fluid in the bathroom passage 101 from leaking through the gap between the connecting joint 2 and the mounting portion 1.

[0071] Figure 8 FIG. 1 shows a schematic structural diagram of the pressing member 5 provided in this embodiment. Figure 9 FIG. 1 shows a schematic structural diagram of the temperature detection element 3 provided in this embodiment. Figure 10 Shown Figure 1 A partial enlarged view at point A. Figures 8-10 As shown, the temperature sensor mounting structure further includes a pressing member 5, one end of which is connected to the mounting portion 1, and the other end of which can press the temperature detecting member 3 against the mounting portion 1. The provision of the pressing member 5 can further improve the stability of the installation of the temperature detecting member 3 and prevent it from falling out of the first mounting hole 11 and the second mounting hole 211 during use.

[0072] Specifically, an annular limiting portion 32 is also protruding from the outer periphery of the detection end 31. When the detection end 31 is extended into the first mounting hole 11 and the second mounting hole 211, the annular limiting portion 32 is partially exposed on the mounting portion 1, and the other end of the clamping member 5 can be pressed against the annular limiting portion 32, thereby ensuring the stable installation of the temperature detection member 3 and the mounting portion 1.

[0073] In this embodiment, the pressing member 5 is connected to the mounting portion 1 by a fastener, which is convenient for assembly and disassembly and has a stable connection. Of course, in other embodiments, the pressing member 5 can also be connected to the mounting portion 1 by other connection methods, which is not limited in this embodiment.

[0074] Optionally, the other end of the pressing member 5 is provided with a notch 51 for the temperature detecting member 3 to pass through. By providing the notch 51 on the pressing member 5, both ends of the notch 51 can form a pressing portion for pressing against the annular limiting portion 32, thereby increasing the contact area between the pressing member 5 and the annular limiting portion 32 and improving the pressing effect; in addition, compared with the solution of providing an avoidance hole on the pressing member 5, the provision of the notch 51 can facilitate the installation of the pressing member 5. After the temperature detecting member 3 is installed on the mounting portion 1, the pressing member 5 can be installed from one side of the temperature detecting member 3 without having to be inserted from the head of the temperature detecting member 3, thereby simplifying the operation process and improving assembly efficiency.

[0075] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
