Description

Technical Field

[0001] The utility model relates to the technical field of valve parts, in particular to a valve body structure for a water outlet valve and a water outlet valve. Background Art

[0002] The water circuit system of a wall-mounted boiler is a water heater powered by natural gas. It has a powerful central heating function for families, can meet the heating needs of multiple rooms, and can provide domestic water for places such as family bathing and kitchens. Among them, the water outlet valve is an essential valve structure in the water circuit system of the wall-mounted boiler.

[0003] In the existing valve body structure of the water outlet valve, the flow channels mostly adopt straight flow channels. When processing the straight flow channels, process holes are usually machined on the valve body structure. When using this water outlet valve, a sealing plug is also required to block the process holes. The setting of the process holes increases potential leakage risk points on the water outlet valve, and the setting of the sealing plug increases the workload during the assembly of the water outlet valve, resulting in low assembly efficiency and high processing cost.

[0004] Therefore, there is an urgent need to propose a valve body structure for a water outlet valve to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a valve body structure for a water outlet valve and a water outlet valve. On the one hand, the number of process holes can be reduced to reduce potential leakage risk points on the water outlet valve.

[0061] Embodiment 1

[0062] Figure 1 The structural schematic diagram of the valve body structure for the water outlet valve provided in this embodiment is shown from one perspective.

[0063] Figure 2 The structural schematic diagram of the valve body structure for the water outlet valve provided in this embodiment is shown from another perspective.

[0064] Figure 3 Shows Figure 2 The cross-sectional schematic diagram at A - A. Figure 4The structural schematic diagram of the water outlet valve 100 provided by this embodiment is shown. As Figures 1 - 4 shown, this embodiment provides a valve body structure for a water outlet valve, which is applied to the water outlet valve 100. The valve body structure for the water outlet valve includes a three-way valve part 11 and a connecting flow channel. The three-way valve part 11 has a valve cavity 110 extending along a first direction, and the first direction is the axial direction of the three-way valve part 11; the axis of the connecting flow channel is inclined relative to the first direction, and the three-way valve part 11 and the connecting flow channel are of an integral structure.

[0065] For the valve body structure for the water outlet valve provided by this embodiment, by providing a connecting flow channel communicated with the valve cavity 110 of the three-way valve part 11 and the connecting flow channel being inclined relative to the axial direction of the three-way valve part 11, compared with the straight channel in the prior art, on the one hand, the number of process holes can be reduced to reduce potential leakage risk points on the valve body structure for the water outlet valve, and on the other hand, the use of sealing plugs can be reduced to reduce the processing cost to a certain extent; by setting the three-way valve part 11 and the connecting flow channel as an integral structure, the assembly link between the three-way valve part 11 and the connecting flow channel can be omitted, shortening the assembly time of the water outlet valve 100, improving the assembly efficiency, and avoiding leakage at the connection between the three-way valve part 11 and the connecting flow channel, improving the use safety of the water outlet valve 100.

[0066] Further, the connecting flow channel includes a heating connecting flow channel 1001 and a heat exchange connecting flow channel 1002. The heating connecting flow channel 1001 is communicated with one end of the valve cavity 110, and the heat exchange connecting flow channel 1002 is communicated with the other end of the valve cavity 110 to realize the three-way switching of the valve body structure for the water outlet valve.

[0067] Specifically, the valve body structure for the water outlet valve further includes an extension valve part 12 and a first valve part 13. The extension valve part 12 is connected to the three-way valve part 11, and a heating channel 121 extending along a second direction is arranged in the extension valve part 12, and the first direction and the second direction are arranged at an angle; the first valve part 13 is connected to the three-way valve part 11, and a first heat exchange water inlet flow channel 131 is arranged in the first valve part 13. The valve cavity 110 and the heating channel 121 are communicated through the heating connecting flow channel 1001, and the valve cavity 110 and the first heat exchange water inlet flow channel 131 are communicated through the heat exchange connecting flow channel 1002. Among them, the heating channel 121 is used to connect to the heating system 500 (refer to Figure 5 ), and the first heat exchange water inlet flow channel 131 is used to connect to the heat exchange structure 300 (refer to Figure 5 ). The above settings are used to realize that the water outlet valve 100 selectively supplies water to the heating system 500 or the heat exchange structure 300 to provide domestic water for users or meet the heating needs of users.

[0068] In this embodiment, the first direction and the second direction are perpendicular to each other. Of course, the specific value of the included angle between the first direction and the second direction in this embodiment is not limited, and the designer can adjust the included angle between the first direction and the second direction according to actual needs.

[0069] As Figure 3 shown, the valve chamber 110 is connected to the heating communication channel 1001 through an arc transition structure. This design can make the connection between the valve chamber 110 and the heating communication channel 1001 smoothly transition and can provide a guiding effect for the water passing through here.

[0070] Optionally, the inclination angle of the heating communication channel 1001 relative to the first direction is 25° to 75°. This angle range can facilitate the processing of the valve body structure for the water outlet valve and can avoid the overall size of the valve body structure for the water outlet valve being too large in the first direction or the second direction, resulting in a large installation space for the water outlet valve 100 and increasing the installation difficulty. Exemplarily, the inclination angle of the heating communication channel 1001 relative to the first direction can be 30°, 40°, 45°, 50°, 60°, etc.

[0071] As Figure 2 shown, the inclination angle of the heat exchange communication channel 1002 relative to the first direction is 25° to 75°. This angle range can facilitate the processing of the valve body structure for the water outlet valve and can avoid the overall size of the valve body structure for the water outlet valve being too large in the first direction or the second direction, resulting in a large installation space for the water outlet valve 100 and increasing the installation difficulty. Exemplarily, the inclination angle of the heat exchange communication channel 1002 relative to the first direction can be 30°, 40°, 45°, 50°, 60°, etc. It should be noted that in actual processing, the inclination angle of the heat exchange communication channel 1002 relative to the first direction and the inclination angle of the heating communication channel 1001 relative to the first direction can be equal or not equal, and this embodiment does not limit this.

[0072] Embodiment Two

[0073] Figure 5 shows a schematic diagram of the water circuit structure of the wall-mounted boiler water circuit system provided in this embodiment. Figure 6 shows a schematic diagram of the structure of the water outlet valve 100 provided in this embodiment from one perspective. Figure 7 shows a schematic diagram of the structure of the water outlet valve 100 provided in this embodiment from another perspective. As Figures 5 - 7As shown in the figure, this embodiment provides a water circuit system for a wall-mounted boiler. The water circuit system of the wall-mounted boiler includes a combustion chamber 200, a heat exchange structure 300, a water inlet valve 400, and a water outlet valve 100. The combustion chamber 200 can heat the water therein; the heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 that are thermally coupled; the water inlet valve 400 can supply water to the combustion chamber 200 and the water supply channel 320; the water outlet valve 100 includes a valve body 1, and the valve body 1 is provided with a hot water inlet 1111, a first heat exchange water inlet flow channel 131, a first heat exchange water outlet flow channel 141, a heating channel 121, and a bathroom channel 142; the hot water inlet 1111 is connected to the hot water outlet 201 of the combustion chamber 200 through a connecting pipeline 600, and the hot water inlet 1111 can be selectively connected to the heating channel 121 or the first heat exchange water inlet flow channel 131; the first heat exchange water inlet flow channel 131 is connected to the inlet of the heat exchange channel 310, the outlet of the heat exchange channel 310 is connected to the second heat exchange water outlet flow channel 402 of the water inlet valve 400, the inlet of the water supply channel 320 is connected to the second heat exchange water inlet flow channel 401 of the water inlet valve 400, and the outlet of the water supply channel 320 is connected to the first heat exchange water outlet flow channel 141. Among them, in this embodiment, the valve body 1 of the water outlet valve 100 can adopt the valve body structure for the water outlet valve in Embodiment 1, which is convenient for processing and can reduce potential leakage risk points on the water outlet valve 100, thereby ensuring the safety of the water outlet valve 100 during use.

[0074] Specifically, during use, when the hot water inlet 1111 is connected to the heating channel 121, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the heating channel 121 in sequence and then flow into the heating system 500 to provide heating requirements for users. The water that has exchanged heat with the outside in the heating system 500 can then flow through the water inlet valve 400 and into the combustion chamber 200 to be heated again, thereby forming a heating water circulation loop; when the hot water inlet 1111 is connected to the first heat exchange water inlet flow channel 131, the hot water heated by the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipeline 600, the hot water inlet 1111, and the first heat exchange water inlet flow channel 131 in sequence and then flow into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the water supply channel 320, it flows through the water inlet valve 400 and into the combustion chamber 200 to be heated again, thereby forming a heat exchange circulation loop; the water in the external water source can flow into the water supply channel 320 of the heat exchange structure 300 through the water inlet valve 400. After exchanging heat with the water in the heat exchange channel 310, it then flows through the first heat exchange water outlet flow channel 141 and the bathroom channel 142 in sequence and into the bathroom system to provide domestic water for users.

[0075] It should be noted that the heating system 500 specifically refers to terminal heat dissipation components such as radiators, floor heating pipes, or fan coil units. The water heated in the combustion chamber 200 can be pumped through the water outlet valve 100 to the above-mentioned terminal heat dissipation components, and the heat is dissipated into the indoor air through heat dissipation, thereby increasing the indoor environmental temperature to meet the heating needs of users. The bathroom system specifically refers to water-using devices for users to take showers, wash, etc. Therefore, both the heating system 500 and the bathroom system are relatively mature technologies in this field, and the specific structures of the heating system 500 and the bathroom system will not be elaborated in this embodiment.

[0076] The material of the connecting pipeline 600 in this embodiment is not limited, and it can be made of copper pipes, corrugated pipes, stainless steel pipes, plastic pipes, etc.

[0077] It should also be noted that both the combustion chamber 200 and the water inlet valve 400 are relatively mature technologies in this field, and the specific structures of the combustion chamber 200 and the water inlet valve 400 will not be elaborated in this embodiment.

[0078] Figure 8 Fig. shows the structural schematic diagram of the water outlet valve 100 provided in this embodiment from another perspective. Figure 9 Fig. shows Figure 8 the sectional structural schematic diagram at B-B. As Figure 8 and Figure 9 and in combination with Figure 3 shown, a threaded structure is provided at the outlet of the heating channel 121. The threaded structure is used to connect the heating joint 5, and the heating joint 5 is used to connect the heating system 500 and the heating channel 121 to ensure a stable connection between the two. In addition, threaded connection has the advantages of firm connection and convenient disassembly and assembly.

[0079] As Figures 6 - 9 shown, a partition component 112 is provided in the valve cavity 110 of the valve body 1. The partition component 112 cooperates with the cavity wall of the valve cavity 110 to form a first cavity 1102, a main valve cavity 1101, and a second cavity 1103 that are arranged at intervals along the first direction. The main valve cavity 1101 can selectively communicate with the first cavity 1102 or the second cavity 1103. The second cavity 1103 is connected to the first heat exchange inlet water flow channel 131 through the heat exchange communication flow channel 1002, and the first cavity 1102 is connected to the heating channel 121 through the heating communication flow channel 1001.

[0080] For the convenience of description, as Figure 6As shown, the height direction of the water outlet valve 100 after actual installation is defined as the up-down direction. Among them, the side of the water outlet valve 100 close to the combustion chamber 200 is defined as up, the side of the water outlet valve 100 away from the combustion chamber 200 is defined as down, the side of the water outlet valve 100 close to the heat exchange structure 300 is defined as back, and the side of the water outlet valve 100 away from the heat exchange structure 300 is defined as front; when the user stands facing the front of the water outlet valve 100, the side of the water outlet valve 100 facing the user's right hand is defined as right, and the side of the water outlet valve 100 facing the user's left hand is defined as left. In addition, the height direction of the valve body 1 refers to the up-down direction, the width direction of the valve body 1 refers to the left-right direction, and the thickness direction of the valve body 1 refers to the front-back direction.

[0081] In this embodiment, the first direction specifically refers to the front-back direction, that is, the three-way valve part 11 extends along the front-back direction. The extending direction of the heating channel 121 is perpendicular to the extending direction of the three-way valve part 11, that is, it extends along the up-down direction. Of course, in other embodiments, the three-way valve part 11 and the extending valve part 12 can also be arranged at other angles, and the above effects can also be achieved.

[0082] As Figure 7 shown, optionally, the valve body 1 further includes a second valve part 14. The second valve part 14 is connected to the extending valve part 12, and the first valve part 13 and the second valve part 14 are arranged at intervals in the up-down direction. The first heat exchange water outlet flow channel 141 and the sanitary ware channel 142 are both opened in the second valve part 14. It should be noted that in this embodiment, the three-way valve part 11 is arranged along the front-back direction, the extending valve part 12 is connected to the lower part of the three-way valve part 11, and the first valve part 13 and the second valve part 14 are respectively connected to the right side of the three-way valve part 11 and the right side of the extending valve part 12, so that the entire valve body 1 is roughly square in layout, making full use of the space of the valve body 1 in the width direction and the thickness direction, greatly reducing the installation height of the entire water circuit system of the wall-mounted boiler, optimizing the space layout of the entire system, and meeting the miniaturization requirements of the water circuit system of the wall-mounted boiler.

[0083] Figure 10 Fig. shows the structural schematic diagram of the switching mechanism 3 and the separating component 112 provided in this embodiment. Figure 11 Fig. shows the sectional structural schematic diagram of the switching mechanism 3 and the separating component 112 provided in this embodiment. As Figures 10 - 11 and combined with Figure 9As shown, the water outlet valve 100 further includes a switching mechanism 3. The switching mechanism 3 is movably disposed in the valve cavity 110 to selectively open the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103. When the switching mechanism 3 opens the passage between the main valve cavity 1101 and the first cavity 1102, the hot water in the combustion chamber 200 can circulate in the heating water circulation loop; when the switching mechanism 3 opens the passage between the main valve cavity 1101 and the second cavity 1103, the hot water in the combustion chamber 200 can circulate in the heat exchange circulation loop. That is, the switching mechanism 3 realizes the switching between the heating water circulation loop and the heat exchange circulation loop to selectively provide domestic water for users or meet the heating needs of users.

[0084] Specifically, the partition assembly 112 includes a first partition sleeve 1121 and a second partition sleeve 1122. The first partition sleeve 1121 and the second partition sleeve 1122 are spaced along the axial direction of the valve cavity 110 and are both sealingly fitted with the cavity wall of the valve cavity 110, thereby dividing the valve cavity 110 into a main valve cavity 1101, a first cavity 1102, and a second cavity 1103. The first partition sleeve 1121 is located between the main valve cavity 1101 and the first cavity 1102, and the second partition sleeve 1122 is located between the main valve cavity 1101 and the second cavity 1103. The switching mechanism 3 includes a valve rod 31, a first sealing seat 32, and a second sealing seat 33. The first sealing seat 32 and the second sealing seat 33 are arranged at intervals along the axial direction of the valve rod 31 and are both connected to the valve rod 31. The valve rod 31 can move along the axial direction of the three-way valve portion 11, thereby driving the first sealing seat 32 and the second sealing seat 33 to move to selectively block the first partition sleeve 1121 by the first sealing seat 32 or block the second partition sleeve 1122 by the second sealing seat 33. When the first sealing seat 32 blocks the first partition sleeve 1121, the second sealing seat 33 is spaced from the second partition sleeve 1122. At this time, the main valve cavity 1101 is connected to the second cavity 1103; when the second sealing seat 33 blocks the second partition sleeve 1122 and the first sealing seat 32 is spaced from the first partition sleeve 1121, the main valve cavity 1101 is connected to the first cavity 1102, thereby realizing three-way switching.

[0085] Such as Figure 9 And in combination with Figure 4As shown, on the wall of the valve chamber 110, a first sealing step 1104 and a second sealing step 1105 are arranged at intervals along its axis direction. The first partition sleeve 1121 can abut against the first sealing step 1104, thereby separating the first chamber 1102 and the main valve chamber 1101; the second partition sleeve 1122 can abut against the second sealing step 1105, thereby separating the main valve chamber 1101 and the second chamber 1103. The settings of the first sealing step 1104 and the second sealing step 1105 can provide a limiting and positioning effect for the first partition sleeve 1121 and the second partition sleeve 1122, thus ensuring the accurate and stable installation between the separating component 112 and the valve chamber 110.

[0086] As Figure 6 and Figure 9 shown, optionally, the water outlet valve 100 further includes a driving mechanism 2. The output end of the driving mechanism 2 is connected to the valve stem 31 to drive the valve stem 31 to move along the axis direction of the three-way valve part 11. In this embodiment, the driving mechanism 2 is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 3, the driving mechanism 2 can also be a stepping motor or other driving devices.

[0087] It should be noted that by arranging the three-way valve part 11 in the front-rear direction, the driving mechanism 2 can also be installed on the front side of the valve body 1 (the driving mechanism in the prior art is usually installed between the valve body and the combustion chamber), so as to avoid the interval area between the valve body 1 and the combustion chamber 200, make full use of the space of the valve body 1 in the thickness direction, further shorten the distance between the valve body 1 and the combustion chamber 200, and reduce the height of the whole water circuit system of the wall-mounted boiler.

[0088] It needs to be explained that in the prior art, the first chamber 1102 is coaxially arranged with the heating channel 121 and extends in the up-down direction. When the switching mechanism 3 opens the passage between the main valve chamber 1101 and the first chamber 1102, the first sealing seat 32 is equivalent to blocking the passage between the first chamber 1102 and the heating channel 121. The water in the main valve chamber 1101 will flow between the periphery of the first sealing seat 32 and the wall of the first chamber 1102, thus generating a large water resistance; while in this embodiment, by setting the inclined heating communication flow channel 1001, an opening can just be formed at the interval in the downward direction along the axis of the three-way valve part 11 between the first sealing seat 32 and the first partition sleeve 1121. The water in the main valve chamber 1101 can flow out from this opening under the action of its own gravity, thereby reducing the water resistance, increasing the water flow rate to a certain extent, and also playing a role in reducing the head damage of the circulating water pump, prolonging the service life of the circulating water pump, and reducing the user's usage cost.

[0089] Figure 12 shows a cross-sectional schematic view of the water outlet valve 100 provided in this embodiment from another perspective. As Figure 12 and in combination withFigure 7 As shown, a connection interface 132 communicating with the first heat exchange water inlet flow channel 131 is further provided on the first valve portion 13. A sensing component 4 can be connected at the connection interface 132 for detecting parameters such as the temperature and pressure of the water in the first heat exchange water inlet flow channel 131. Optionally, the sensing component 4 can be but is not limited to a pressure switch, a pressure sensor, a pressure gauge, a temperature sensor, etc.

[0090] Continuing as Figure 6 and Figure 9 As shown, a bypass flow channel 151 is further provided on the valve body 1. The bypass flow channel 151 can selectively communicate the heating channel 121 and the second chamber 1103. When the main valve chamber 1101 communicates with the first chamber 1102, when the heat exchange structure 300 dries out due to lack of water, the water in the heating channel 121 can flow through the bypass flow channel 151 and successively through the second chamber 1103, the heat exchange communication flow channel 1002, and the first heat exchange water inlet flow channel 131 into the heat exchange channel 310 to prevent the heat exchange structure 300 from being damaged due to dry burning caused by lack of water.

[0091] Specifically, the valve body 1 further includes a bypass valve portion 15. The bypass valve portion 15 is formed on the extended valve portion 12. The bypass flow channel 151 is opened in the bypass valve portion 15, and a check valve 1511 is provided in the bypass flow channel 151 to only allow the water in the heating channel 121 to flow into the second chamber 1103 and prevent the water in the second chamber 1103 from flowing back. Among them, the check valve 1511 is a relatively common valve structure in the art, and the specific structure and working principle of the check valve 1511 will not be elaborated in this embodiment.

[0092] Optionally, a bypass port 152 communicating with the bypass flow channel 151 is opened on the bypass valve portion 15. A bypass plug 153 is detachably plugged at the bypass port 152. One end of the check valve 1511 abuts against the inner side of the bypass plug 153. When maintenance is required, the operator only needs to open the bypass plug 153, which is convenient and fast.

[0093] As Figure 6 shown, in this embodiment, the bypass valve portion 15 is formed on the front side of the extended valve portion 12, that is, the bypass valve portion 15 is located below the driving mechanism 2. The operator can perform maintenance on it from the front of the valve body 1 without having to remove the entire outlet valve 100, further improving the convenience of the operator's operation; and this design makes the bypass valve portion 15 located between the three-way valve portion 11 and the extended valve portion 12, making the structure of the entire outlet valve 100 more compact and the bypass connection distance shorter, thereby being able to shorten the response time.

[0094] In this embodiment, the axial direction of the bypass valve portion 15 is parallel to the axial direction of the three-way valve portion 11, that is, the bypass valve portion 15 also extends in the front-rear direction.

[0095] Of course, in other embodiments, the axial direction of the bypass valve portion 15 may also be set at an angle to the axial direction of the three-way valve portion 11. In this example, for the convenience of maintenance by the operator, the extension direction of the bypass valve portion 15 may be set to gradually incline downward along the direction away from the extension valve portion 12, so as to prevent the bypass plug 153 from being blocked by the driving mechanism 2 and affecting the operation of the operator.

[0096] Figure 13 Fig. 4 shows a schematic structural diagram of the water circuit system of the wall-mounted boiler provided in this embodiment. Figure 14 Fig. 5 shows a schematic structural diagram of the water circuit system of the wall-mounted boiler provided by the prior art. As Figure 13 and in combination with Figure 5 、 Figure 6 shown, the hot water inlet 1111 is opened on the three-way valve portion 11 and is communicated with the main valve cavity 1101 to receive the hot water flowing out from the hot water outlet 201 of the combustion chamber 200. In this embodiment, the hot water inlet 1111 on the three-way valve portion 11 is arranged facing the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 1111 and the hot water outlet 201 are directly communicated through the connecting pipeline 600. Compared with Figure 10 the scheme shown in Fig. 6 in which the hot water inlet 1111 is arranged on the side surface of the valve body 1, by adopting the above setting method, after the connecting pipeline 600 is led out from the hot water outlet 201, it can be directly pulled down to the hot water inlet 1111, thereby shortening the distance between the hot water inlet 1111 and the hot water outlet 201, reducing the length and material consumption of the connecting pipeline 600, and further reducing the material cost to a certain extent; in addition, the above setting also enables the connecting pipeline 600 to be processed into a straight pipe structure, and the communication between the hot water inlet 1111 and the hot water outlet 201 can be realized without too many bending parts, thus avoiding the phenomenon of large water resistance caused by too many bending parts on the connecting pipeline 600.

[0097] In this embodiment, the hot water inlet 1111 is coaxially arranged with the heating channel 121, and the first cavity 1102 and the second cavity 1103 are respectively located on both sides of the axis of the hot water inlet 1111, so as to facilitate the processing of the valve body 1. Of course, in other embodiments, the axis of the hot water inlet 1111 and the axis of the heating channel 121 may also be set to be parallel but not coaxial, and the above effects can also be achieved.

[0098] Embodiment III

[0099] This embodiment provides a water outlet valve 100. The specific structure of the water outlet valve 100 is substantially the same as that of the water outlet valve 100 in Embodiment I, except that: the setting direction of the bypass valve portion 15 is different.

[0100] Figure 15 Fig. 7 shows a schematic structural diagram of the water outlet valve 100 provided in this embodiment from one perspective.Figure 16 A schematic structural diagram of the water outlet valve 100 provided in this embodiment from another viewing angle is shown. Figure 17 Shows Figure 16 Schematic diagram of the cross-sectional structure at CC. Figures 15 - 17 As shown, in this embodiment, the bypass valve part 15 is connected to the side of the three-way valve part 11 away from the first valve part 13 (i.e., the left side of the valve body 1), and a bypass flow channel 151 is provided in the bypass valve part 15, and the bypass flow channel 151 can selectively connect the first chamber 1102 and the second chamber 1103. When the main valve chamber 1101 is connected to the first chamber 1102, when the heat exchange structure 300 is dry-burned due to lack of water, the water in the first chamber 1102 can flow through the bypass flow channel 151 and the second chamber 1103, the heat exchange connecting flow channel 1002, and the first heat exchange water inlet flow channel 131 to the heat exchange channel 310, so as to avoid damage to the heat exchange structure 300 due to dry-burning due to lack of water.

[0101] In this embodiment, the axis of the bypass valve portion 15 is inclined relative to the axis of the three-way valve portion 11, and the bypass plug 153 on the bypass port 152 is arranged forward, so that it is convenient for the operator to open the bypass plug 153 when inspecting the bypass valve portion 15, and there is no need to remove the entire water outlet valve 100 from the heat exchange structure 300. This is convenient and quick, and can reduce the maintenance workload of the operator and reduce labor costs.

[0102] It should be noted that, in this embodiment, since the bypass valve portion 15 is connected to the left side of the three-way valve portion 11, the first valve portion 13 is located on the right side of the three-way valve portion 11, and the extended valve portion 12 is located at the lower part of the three-way valve portion 11, therefore, in this example, the hot water inlet 1111 is opened at the top of the three-way valve portion 11, making full use of the space of the three-way valve portion 11 in all directions to achieve the optimization of the spatial layout of the entire system.

[0103] Embodiment 4

[0104] This embodiment provides a water outlet valve 100 , the specific structure of which is substantially the same as the specific structure of the water outlet valve 100 in the first embodiment, except that the location of the hot water inlet 1111 is different.

[0105] Figure 18 FIG. 1 shows a schematic diagram of the structure of the water outlet valve 100 provided in this embodiment. Figure 18 Combined with Figure 5As shown, in this embodiment, the hot water inlet 1111 is provided on the side of the three-way valve portion 11 away from the first valve portion 13, that is, the hot water inlet 1111 is opened on the left side of the three-way valve portion 11. By adopting this setting method, the size of the entire water outlet valve 100 in the height direction can be further reduced, and when assembling the water circuit system of the wall-mounted boiler, only the space for connecting the connecting pipe 600 and the hot water outlet 201 of the combustion chamber 200 needs to be reserved between the top of the combustion chamber 200 and the valve body 1.
