Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a water outlet valve. Background Technology

[0002] A wall-hung boiler water system is a type of water heater that uses natural gas as its energy source. It boasts powerful central heating capabilities, meeting the heating needs of multiple rooms and providing domestic hot water for bathing, kitchens, and other areas. The outlet valve is an essential component of the wall-hung boiler water system. Its main function is to control the opening and closing of the inlet and outlet, the diversion of water flow, and the direction and flow rate of the water, thereby ensuring the even distribution of hot water within the pipes and the proper heating of the radiators.

[0003] However, the outlet valves in related technologies typically have the following problems during use:

[0004] 1) The three-way valve chamber of the outlet valve is coaxially set with the heating channel, and the axis of the three-way valve chamber extends in the vertical direction during installation, resulting in a large size of the outlet valve in the height direction. This leads to a high installation height of the entire wall-hung boiler water circuit system, which cannot meet the market demand for miniaturization of the wall-hung boiler water circuit system.

[0005] 2) In order to ensure stable water pressure in the water circuit system of the wall-hung boiler and achieve reasonable control of the circulating water flow, the outlet valve often needs to be connected to an external bypass pipe with water replenishment function. However, the external bypass pipe often occupies a large amount of installation space for the outlet valve, which is not conducive to the installation of the outlet valve in narrow spaces such as control cabinets and valve wells.

[0006] This section provides background information related to the present invention, which is not necessarily prior art. Utility Model Content

[0007] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a water outlet valve that, on the one hand, fully utilizes the space in the thickness direction of the valve body to reduce the height of the water outlet valve, thereby meeting the miniaturization requirements of the wall-hung boiler water system; on the other hand, it can promptly replenish water when the heating water system is short of water, preventing the wall-hung boiler from dry-burning, thus extending the service life of the entire wall-hung boiler water system.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A water outlet valve includes a valve body, the valve body having a three-way valve chamber, a heating channel, a first heat exchange inlet channel and a first heat exchange outlet channel, the first heat exchange inlet channel and the first heat exchange outlet channel being used to connect a heat exchange structure, the three-way valve chamber being selectively connected to the heating channel or the first heat exchange inlet channel, and the water outlet valve further including a water supply component.

[0010] The axial direction of the three-way valve chamber is set at an angle to the axial direction of the heating channel;

[0011] The valve body is also provided with a water inlet channel, a water outlet channel, and a sealing port that connects the two. The water inlet channel is connected to the first heat exchange outlet channel, and the water outlet channel is connected to the first heat exchange inlet channel. The water supply component is adjustablely installed on the valve body, and the output end of the water supply component can move towards or away from the sealing port to selectively open the passage between the water inlet channel and the water outlet channel.

[0012] As a preferred embodiment of the water outlet valve provided by this utility model, the water replenishment component is a solenoid valve assembly, which includes:

[0013] An electromagnetic coil is mounted on the valve body;

[0014] A sealing element is connected to the output end of the electromagnetic coil to move closer to or further away from the sealing opening under the driving action of the electromagnetic coil.

[0015] As a preferred embodiment of the water outlet valve provided by this utility model, the sealing port is provided with an annular protrusion.

[0016] As a preferred embodiment of the water outlet valve provided by this utility model, a one-way valve is provided in the water supply outlet channel to allow fluid to flow from the water supply outlet channel to the first heat exchange inlet channel only.

[0017] As a preferred embodiment of the water outlet valve provided by this utility model, the valve body includes:

[0018] A three-way valve section, wherein a three-way valve cavity is provided within the three-way valve section, and the three-way valve cavity extends along a first direction;

[0019] A heating valve section is connected to the three-way valve section, and the heating valve section has a heating channel that extends along the second direction;

[0020] The heat exchange valve section is connected to the three-way valve section and the heating valve section on one side along the third direction, and the first heat exchange inlet channel, the first heat exchange outlet channel, the water replenishment inlet channel, the water replenishment outlet channel and the sealing port are all opened in the heat exchange valve section.

[0021] The first direction, the second direction, and the third direction are arranged at an angle to each other.

[0022] As a preferred embodiment of the outlet valve provided by this utility model, the valve body further includes a bypass valve section, which is connected to the heating valve section, and the bypass valve section has a bypass flow channel and a pressure relief channel, the pressure relief channel being connected to the outside.

[0023] The bypass channel is provided with a bypass valve core and a pressure relief valve core. The bypass valve core and the pressure relief valve core are spaced apart and can be movable. The space between them forms a pressure relief main chamber. The pressure relief main chamber is connected to the side of the three-way valve chamber near the first heat exchange inlet channel. The bypass valve core can selectively open the passage between the heating channel and the pressure relief main chamber. The pressure relief valve core can selectively open the passage between the pressure relief main chamber and the pressure relief channel.

[0024] As a preferred embodiment of the outlet valve provided by this utility model, the spring preload of the pressure relief valve core is greater than the spring preload of the bypass valve core.

[0025] As a preferred embodiment of the water outlet valve provided by this utility model, the outlet of the pressure relief channel is arranged facing downwards.

[0026] As a preferred embodiment of the outlet valve provided by this utility model, the bypass valve section is located on the front side of the heating valve section.

[0027] As a preferred embodiment of the water outlet valve provided by this utility model, the valve body is provided with a pressure detection element, which is used to detect the pressure in the three-way valve cavity, and the pressure detection element is electrically connected to the water supply component.

[0028] The beneficial effects of this utility model are as follows:

[0029] The water outlet valve provided by this utility model, by setting the axis of the three-way valve chamber at an angle to the axis of the heating channel, compared with the prior art where the three-way valve chamber and the heating channel are coaxial, allows the three-way valve chamber and the heating channel to be set in two different directions. This avoids the valve body being too long along the axis of the three-way valve chamber, thereby optimizing the spatial layout of the entire water outlet valve, reducing the installation height of the wall-hung boiler water circuit system, and meeting the miniaturization requirements of the wall-hung boiler water circuit system. By setting a water replenishment component, when the heating water circuit is short of water, the output end of the water replenishment component can move away from the sealing port. By opening the sealing port, water in the first heat exchange outlet channel flows sequentially through the water inlet channel, the sealing port, and the water outlet channel back to the first heat exchange inlet channel. This water then replenishes the heating water circuit through the heat exchange structure, ensuring stable water pressure throughout the entire wall-hung boiler water system and preventing dry burning, thus extending the service life of the entire system. By placing the water inlet and outlet channels inside the valve body, the external bypass pipe required in existing technologies is eliminated, reducing the overall size of the outlet valve, further optimizing its spatial layout, and reducing material costs to some extent.

[0046] Before explaining any embodiment of the present invention in detail, it should be understood that the present invention is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0047] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0049] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0050] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0053] Figure 1 The diagram shows the water circuit structure of the wall-hung boiler water circuit system provided in this embodiment. Figure 2 A schematic diagram of the water outlet valve 100 provided in this embodiment is shown from one perspective. (See diagram below.) Figure 1 As shown, this embodiment provides a water outlet valve 100, which is applied to the water circuit system of a wall-hung boiler. The water circuit system includes a combustion chamber 200, a heat exchange structure 300, an inlet valve 400, and a water outlet valve 100. The combustion chamber 200 heats the water within it; the heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 that are thermally fitted together; the inlet valve 400 supplies water to the combustion chamber 200 and the water supply channel 320; the water outlet valve 100 includes a valve body 1, which has a hot water inlet 111, a first heat exchange inlet channel 131, a first heat exchange outlet channel 132, a heating channel 121, and a bathroom channel 133; the hot water inlet... Hot water inlet 111 is connected to hot water outlet 201 of combustion chamber 200 via connecting pipe 600, and hot water inlet 111 can be selectively connected to heating channel 121 or first heat exchange water inlet channel 131; first heat exchange water inlet channel 131 is connected to inlet of heat exchange channel 310, outlet of heat exchange channel 310 is connected to second heat exchange water outlet channel 402 of inlet valve 400, inlet of water supply channel 320 is connected to second heat exchange water inlet channel 401 of inlet valve 400, and outlet of water supply channel 320 is connected to first heat exchange water outlet channel 132.

[0054] In use, when the hot water inlet 111 is connected to the heating channel 121, the hot water heated by the combustion chamber 200 flows sequentially through the hot water outlet 201, connecting pipe 600, hot water inlet 111, and heating channel 121 into the heating system 500 to provide heating for users. The water in the heating system 500, after heat exchange with the outside environment, can flow back to the combustion chamber 200 through the inlet valve 400 for reheating, thus forming a heating water circulation loop. When the hot water inlet 111 is connected to the first heat exchange inlet channel 131, the hot water heated by the combustion chamber 200 flows sequentially through the hot water outlet 201, connecting pipe 600, hot water inlet 111, and heating channel 121 into the heating system 500 to provide heating for users. The hot water flows through inlet 201, connecting pipe 600, hot water inlet 111, and first heat exchange inlet channel 131 into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the supply channel 320, it flows through inlet valve 400 into the combustion chamber 200 for reheating, thus forming a heat exchange circulation loop. Water from an external water source can flow through inlet valve 400 into the supply channel 320 of the heat exchange structure 300. After exchanging heat with the water in the heat exchange channel 310, it flows sequentially through the first heat exchange outlet channel 132 and the bathroom channel 133 into the bathroom system to provide domestic water for users. It should be noted that the combustion chamber 200, heat exchange structure 300, and inlet valve 400 are all relatively mature technologies in the field. The specific structures of the combustion chamber 200, heat exchange structure 300, and inlet valve 400 will not be described in detail in this embodiment.

[0055] Figure 2 The diagram shows a structural schematic of the outlet valve 100 provided in this embodiment from one perspective.

[0056] Figure 3 A schematic diagram of the outlet valve 100 provided in this embodiment is shown from another perspective.

[0057] Figure 4 A first cross-sectional view of the outlet valve 100 provided in this embodiment is shown. Figures 2-4 and combined Figure 1 As shown, in this embodiment, the valve body 1 has a three-way valve chamber 110 connected to the hot water inlet 111. The three-way valve chamber 110 can selectively connect to the heating channel 121 or the first heat exchange inlet channel 131. The axial direction of the three-way valve chamber 110 is set at an angle to the axial direction of the heating channel 121. Compared with the prior art where the three-way valve chamber 110 and the heating channel 121 are coaxially arranged, this design can set the three-way valve chamber 110 and the heating channel 121 in two different directions, so as to avoid the valve body 1 being too long along the axial direction of the three-way valve chamber 110, thereby optimizing the spatial layout of the entire outlet valve 100, reducing the installation height of the wall-hung boiler water circuit system, and meeting the miniaturization requirements of the wall-hung boiler water circuit system.

[0058] Specifically, the valve body 1 includes a three-way valve section 11, a heating valve section 12, and a heat exchange valve section 13. The three-way valve section 11 has a three-way valve cavity 110, which extends along a first direction. The heating valve section 12 is connected to the three-way valve section 11 and has a heating channel 121, which extends along a second direction. The heat exchange valve section 13 is connected to the three-way valve section 11 and the heating valve section 12 on one side along a third direction. The first heat exchange inlet channel 131, the first heat exchange outlet channel 132, and the bathroom channel 133 are all located within the heat exchange valve section 13. The first direction, the second direction, and the third direction are arranged at angles to each other. This design allows the entire structural dimensions of the valve body 1 to be distributed across three directions arranged at angles to each other in three-dimensional space, further avoiding the situation where the length of the valve body 1 along the axis of the three-way valve cavity 110 is too long, thereby optimizing the spatial layout of the entire outlet valve 100.

[0059] It needs to be explained that, such as Figures 1-3 As shown, the height direction of the outlet valve 100 after actual installation is defined as the up-down direction. Specifically, the side of the outlet valve 100 closest to the combustion chamber 200 is defined as up, the side of the outlet valve 100 away from the combustion chamber 200 is defined as down, the side of the outlet valve 100 closest to the heat exchange structure 300 is defined as rear, and the side of the outlet valve 100 away from the heat exchange structure 300 is defined as front. When the user stands facing the outlet valve 100, the side of the outlet valve 100 facing the user's right hand is defined as right, and the side of the outlet valve 100 facing the user's left hand is defined as left. Furthermore, 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. Specifically, the first direction refers to the front-back direction, the second direction refers to the up-down direction, and the third direction refers to the left-right direction.

[0060] In other words, in this embodiment, the three-way valve section 11 extends in the front-to-back direction, the heating valve section 12 is connected to the lower part of the three-way valve section 11, and the heat exchange valve section 13 is connected to the right side of the three-way valve section 11 and the heating valve section 12, so that the entire valve body 1 is roughly square in shape, making full use of the space of the valve body 1 in the width and thickness directions, greatly reducing the installation height of the entire wall-hung boiler water circuit system, and optimizing the spatial layout of the entire system.

[0061] Optionally, such as Figure 4As shown, the three-way valve chamber 110 includes a first chamber 1102, a main valve chamber 1101, and a second chamber 1103 connected sequentially along a first direction. The main valve chamber 1101 is connected to the hot water inlet 111, and the main valve chamber 1101 can selectively connect to either the first chamber 1102 or the second chamber 1103. The heating passage 121 is connected to the first chamber 1102, and the first heat exchange inlet passage 131 is connected to the second chamber 1103. When the main valve chamber 1101 is connected to the first chamber 1102, the hot water in the combustion chamber 200 can circulate in the heating water circulation loop; when the main valve chamber 1101 is connected to the second chamber 1103, the hot water in the combustion chamber 200 can circulate in the heat exchange circulation loop.

[0062] Optionally, the outlet valve 100 further includes a switching mechanism 5, which is movably disposed in the three-way valve chamber 110 to selectively connect the three-way valve chamber 110 to the heating channel 121 or the first heat exchange inlet channel 131. That is, through the movement of the switching mechanism 5 in the three-way valve chamber 110, the passage between the main valve chamber 1101 and the first chamber 1102, or the passage between the main valve chamber 1101 and the second chamber 1103, can be selectively opened, thereby achieving three-way switching. The specific structure and working principle of the switching mechanism 5 will not be elaborated in this embodiment. Any switching mechanism in the prior art that can be applied to the outlet valve 100 to achieve three-way switching in the three-way valve chamber 110 is within the protection scope of this embodiment.

[0063] Furthermore, the outlet valve 100 also includes a drive mechanism 4, the output end of which is connected to a switching mechanism 5 to drive the switching mechanism 5 to move within the three-way valve chamber 110. In this embodiment, the drive mechanism 4 is a synchronous motor. Of course, in other embodiments, depending on the different designs of the switching mechanism 5, the drive mechanism 4 may also be a stepper motor or other drive devices.

[0064] It should be noted that by arranging the three-way valve section 11 in the front-rear direction, the drive mechanism 4 can also be installed on the front side of the valve body 1 (in the prior art, the drive mechanism is usually installed between the valve body and the combustion chamber, that is, the drive mechanism is installed on the upper part of the valve body 1), so as to avoid the gap 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, so as to reduce the height of the entire wall-hung boiler water circuit system.

[0065] Figure 5 A second cross-sectional view of the outlet valve 100 provided in this embodiment is shown. Figure 5 and combined Figure 2 As shown, the outlet valve 100 also includes a water replenishment component 2, which is configured to replenish water to the heating water circuit when there is a water shortage, so as to prevent the wall-hung boiler from burning dry.

[0066] Specifically, the valve body 1 is also provided with a water inlet channel 1341, a water outlet channel 1342, and a sealing port 1343 that connects the two. The water inlet channel 1341 is connected to the first heat exchange outlet channel 132, and the water outlet channel 1342 is connected to the first heat exchange inlet channel 131. The water supply component 2 is adjustablely installed on the valve body 1, and the output end of the water supply component 2 can move towards or away from the sealing port 1343 to selectively open the passage between the water inlet channel 1341 and the water outlet channel 1342. By setting up the water replenishment component 2, when the heating water circuit is short of water, the output end of the water replenishment component 2 can move away from the sealing port 1343 to open the sealing port 1343. This allows the water in the first heat exchange outlet channel 132 to flow sequentially through the water replenishment inlet channel 1341, the sealing port 1343, and the water replenishment outlet channel 1342 back to the first heat exchange inlet channel 131. Then, through the heat exchange structure 300, water is replenished to the heating water circuit to ensure stable water pressure in the entire wall-hung boiler water circuit system and to prevent the wall-hung boiler from dry burning, thereby extending the service life of the entire wall-hung boiler water circuit system. By opening the water replenishment inlet channel 1341 and the water replenishment outlet channel 1342 inside the valve body 1, the setting of the external bypass pipe in the prior art is omitted, thereby reducing the size of the entire outlet valve 100, further optimizing the spatial layout of the outlet valve 100, and reducing material costs to a certain extent.

[0067] Figure 6 A cross-sectional view of the water replenishment component 2 provided in this embodiment is shown. Figure 6 and combined Figure 5 As shown, the water supply component 2 is a solenoid valve assembly, which includes a solenoid coil 21 and a sealing element 22. The solenoid coil 21 is mounted on the valve body 1; the sealing element 22 is connected to the output end of the solenoid coil 21, so as to move closer to or further away from the sealing port 1343 under the driving action of the solenoid coil 21. The solenoid valve assembly has the advantages of high efficiency, reliability, safety, easy automation control, energy saving and strong adaptability. It can automatically and timely replenish water to the heating water circuit, which can greatly save manpower and improve the user experience.

[0068] In this embodiment, the sealing element 22 includes a sealing seat 221 and a sealing gasket 222. The sealing seat 221 is connected to the output end of the electromagnetic coil 21, and the sealing gasket 222 is fixedly installed on the lower side of the sealing seat 221. The sealing gasket 222 can be made of rubber, which is soft. The sealing seat 221 supports the sealing gasket 222, thereby achieving a good sealing effect. The specific structure and working principle of the electromagnetic coil 21 are prior art and will not be described in detail here. Optionally, an annular protrusion is provided on the sealing opening 1343. The annular protrusion allows the sealing gasket 222 to form linear contact with the annular protrusion when sealing the sealing opening 1343, providing a more reliable sealing effect.

[0069] like Figure 2 and Figure 3 As shown, a pressure detection element 3 is installed on the valve body 1. The pressure detection element 3 is used to detect the pressure inside the three-way valve chamber 110, and it is electrically connected to the water supply component 2. By installing the pressure detection element 3, the water shortage signal of the heating water circuit can be obtained by detecting the pressure inside the three-way valve chamber 110, so as to accurately control the start-up timing of the water supply component 2 and achieve timely and accurate water supply to the heating water circuit. In addition, by obtaining the pressure inside the three-way valve chamber 110, the water volume inside the combustion chamber 200 can also be indirectly obtained, so that the combustion chamber 200 can be started for heating when the water volume is sufficient, thus preventing dry burning.

[0070] like Figure 5 As shown, a one-way valve 135 is installed in the water supply outlet channel 1342 to allow only fluid (specifically water) to flow from the water supply outlet channel 1342 to the first heat exchange inlet channel 131, preventing water in the first heat exchange inlet channel 131 from flowing back into the first heat exchange outlet channel 132 through the water supply outlet channel 1342, thus affecting the quality of the user's domestic water. The one-way valve 135 is a relatively mature valve structure in the prior art, and its specific structure and working principle will not be described in detail in this embodiment.

[0071] Figure 7 It shows Figure 4 A magnified view of a portion at point A. (See attached image.) Figure 7 and combined Figure 3 As shown, the valve body 1 also includes a bypass valve section 15, which is connected to the heating valve section 12. The bypass valve section 15 has a bypass flow channel 151 and a pressure relief channel 152, with the pressure relief channel 152 communicating with the outside. A bypass valve core 141 and a pressure relief valve core 142 are provided in the bypass flow channel 151. The bypass valve core 141 and the pressure relief valve core 142 are spaced apart and movable, and the space between them forms a pressure relief main chamber. The pressure relief main chamber is connected to the side of the three-way valve chamber 110 near the first heat exchange inlet flow channel 131. The bypass valve core 141 can selectively open the passage between the heating channel 121 and the pressure relief main chamber, and the pressure relief valve core 142 can selectively open the passage between the pressure relief main chamber and the pressure relief channel 152. Specifically, the "side of the three-way valve chamber 110 near the first heat exchange inlet flow channel 131" refers to the second chamber 1103.

[0072] By setting a bypass valve section 15, and movably installing a bypass valve core 141 and a pressure relief valve core 142 in the bypass flow channel 151 of the bypass valve section 15, when the three-way valve chamber 110 is connected to the heating channel 121, when the water pressure in the heating channel 121 is high, the water in the heating channel 121 can push the bypass valve core 141 to move, thereby opening the passage between the heating channel 121 and the pressure relief main chamber. This allows the water in the heating channel 121 to flow through the pressure relief main chamber, the three-way valve chamber 110, and the first heat exchange inlet flow channel 131 to the heat exchange structure 300, thus achieving the function of pressure relief and replenishing water to the heat exchange structure 300, preventing damage to the heat exchange structure 300 due to dry burning due to lack of water, thereby ensuring the operation of the entire wall-hung boiler water system. For safety reasons; if the pressure in the heating channel 121 is too high, the water circulation inside the wall-hung boiler water system still cannot achieve the effect of pressure relief. At this time, the water in the main pressure relief chamber can push the pressure relief valve core 142 to move, so as to open the passage between the main pressure relief chamber and the pressure relief channel 152, thereby allowing the pressure in the outlet valve 100 to be discharged to the outside through the pressure relief channel 152, thus achieving the effect of pressure relief; when the three-way valve chamber 110 is connected to the first heat exchange inlet channel 131, if the internal pressure of the valve body 1 is high, the water in the main pressure relief chamber can also push the pressure relief valve core 142 to move, so as to open the passage between the main pressure relief chamber and the pressure relief channel 152, thereby allowing the pressure in the outlet valve 100 to be discharged to the outside through the pressure relief channel 152, thus achieving the effect of pressure relief. The outlet valve 100 integrates the bypass valve core 141 and the pressure relief valve core 142 into the bypass valve section 15, which is equivalent to integrating the bypass valve and the safety valve in the prior art. This can reduce the overall size of the outlet valve 100 to a certain extent, making it easier to install, and further ensuring the safety of the entire wall-hung boiler water circuit system.

[0073] Optionally, the spring preload of the pressure relief valve core 142 is greater than the spring preload of the bypass valve core 141. The purpose of this arrangement is that when the internal pressure of the valve body 1 is high, pressure relief can be achieved primarily through the internal water circulation of the boiler's water system. Specifically, water in the heating channel 121 opens the bypass valve core 141, flowing through the main pressure relief chamber, the three-way valve chamber 110, and the first heat exchange inlet channel 131 to the heat exchange structure 300. If complete pressure relief cannot be achieved through the internal water circulation of the boiler's water system, the pressure relief valve core 142 opens the passage between the main pressure relief chamber and the pressure relief channel 152 to release the internal pressure of the valve body 1 to the outside. This design reduces the activation frequency of the pressure relief valve core 142, thereby extending its service life. Optionally, the outlet of the pressure relief channel 152 is set downward so that when the valve body 1 needs to release pressure to the outside, the water flowing from the main pressure relief chamber to the pressure relief channel 152 can flow out quickly under its own gravity, ensuring the timeliness of the pressure relief process.

[0074] In this embodiment, the bypass valve core 141 is a one-way valve core structure, allowing only water in the heating channel 121 to flow through the pressure relief main chamber to the three-way valve chamber 110, thus preventing backflow of water in the three-way valve chamber 110. The one-way valve core structure is a commonly used valve structure in the art, and the specific structure and working principle of the bypass valve core 141 will not be described in detail in this embodiment. Furthermore, this embodiment does not limit the specific structure of the pressure relief valve core 142; any pressure relief valve core in the prior art that can achieve a pressure relief effect is within the protection scope of this embodiment.

[0075] like Figure 3 As shown, to facilitate maintenance by operators, the bypass valve section 15 is connected to the front side of the heating valve section 12. Operators can perform maintenance on the outlet valve 100 from the front without disassembling the entire outlet valve 100, improving operational convenience. In this embodiment, the axial direction of the bypass valve section 15 is parallel to the axial direction of the three-way valve section 11, meaning the bypass valve section 15 also extends in the front-to-back direction. This design allows the bypass valve section 15 to be located between the three-way valve section 11 and the heating valve section 12, making the overall structure of the outlet valve 100 more compact, the bypass connection distance shorter, and thus shortening the response time. Of course, in other embodiments, the axial direction of the bypass valve section 15 can also be set at an angle to the axial direction of the three-way valve section 11. In this example, to facilitate maintenance of the bypass valve section 15 by the operator, the extension direction of the bypass valve section 15 can be set to gradually slope downwards in a direction away from the heating valve section 12, so as to avoid the end of the pressure relief valve core 142 interfering with other structures and affecting the operator's operation.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
