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] The valve body of the outlet valve typically includes a three-way valve chamber, a heating channel, a first flow channel, a second flow channel, and a bathroom channel. The three-way valve chamber comprises a first chamber, a main valve chamber, and a second chamber arranged sequentially along the axis of the three-way valve section. The main valve chamber can selectively connect to either the first or second chamber. The heating channel is connected to the first chamber. The first and second flow channels are used to connect to the plate heat exchanger of the wall-hung boiler system. The first flow channel is connected to the second chamber, and the second flow channel is connected to the bathroom channel, thereby providing domestic hot water to users and meeting their heating needs. In related technologies, the valve body also includes a bypass flow channel, with its two ends connected to the heating channel and the second chamber, respectively. This allows fluid in the heating channel to be introduced into the second chamber via the bypass flow channel when the main valve chamber is connected to the first chamber, thus ensuring the pressure balance of the entire wall-hung boiler system. However, in this configuration, the bypass flow channel is usually quite long, which increases the flow path of fluid from the heating channel into the second chamber to some extent, affecting the pressure regulation efficiency of the wall-hung boiler system.

[0004] Therefore, there is an urgent need for a water outlet valve to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a water outlet valve that can shorten the length of the bypass channel, improve the pressure regulation efficiency of the wall-hung boiler system, and thus ensure the pressure balance of the entire wall-hung boiler system.

[0008] The valve body includes a three-way valve section and a bypass valve section, wherein the bypass valve section is connected to the first side of the three-way valve section;

[0009] The three-way valve section has a first chamber, a main valve chamber, and a second chamber arranged sequentially along its axial direction. The main valve chamber can selectively connect to the first chamber or the second chamber.

[0010] The bypass valve section has a bypass flow channel and a connecting flow channel. The first end of the bypass flow channel is connected to the main valve chamber. The two ends of the connecting flow channel are respectively connected to the second end of the bypass flow channel and the second chamber. The projection of the bypass flow channel on the three-way valve section is located in the area where the main valve chamber is provided in the three-way valve section.

[0011] The one-way valve assembly is disposed in the bypass channel and can selectively open the passage between the bypass channel and the main valve chamber to allow fluid in the main valve chamber to flow to the second chamber via the bypass channel and the connecting channel.

[0015] As a preferred embodiment of the water outlet valve provided by this utility model, the valve body further includes a side valve section connected to the second side of the three-way valve section. The side valve section has a bathroom channel and a water supply channel. The two ends of the water supply channel are respectively connected to the bathroom channel and the main valve chamber.

[0016] The outlet valve also includes a water replenishment component, which includes a water replenishment valve core that is movably disposed in the path of the water replenishment channel. The water replenishment valve core can selectively open or cut off the water replenishment channel.

[0017] As a preferred embodiment of the water outlet valve provided by this utility model, the water supply channel includes a first branch channel and a second branch channel that are arranged at an angle and can be connected. One end of the first branch channel is connected to the bathroom channel, and one end of the second branch channel is connected to the main valve cavity. The water supply valve core is movably disposed at the connection between the first branch channel and the second branch channel.

[0018] As a preferred embodiment of the water outlet valve provided by this utility model, a water supply connection port is formed in the water supply channel, and the water supply component further includes a water supply sleeve, which is sealed and connected to the side valve part; the water supply valve core is movably disposed in the water supply sleeve along the axial direction of the water supply sleeve, and one end of the water supply valve core extends into the water supply channel and is sealed and cooperates with the water supply connection port.

[0019] As a preferred embodiment of the water outlet valve provided by this utility model, the water replenishment assembly further includes a driving component. The other end of the water replenishment valve core extends out of the water replenishment sleeve and is connected to the output end of the driving component. The driving component can drive the water replenishment valve core to move axially along the water replenishment sleeve.

By setting the first end of the bypass flow channel to be connected to the main valve chamber, and the projection of the bypass flow channel on the three-way valve section being located in the area of ​​the three-way valve section where the main valve chamber is located, the total length of the bypass flow channel and the connecting flow channel can be reduced, shortening the flow path of the fluid from the main valve chamber to the second chamber, thereby achieving rapid pressure relief of the system.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0042] In this utility model, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. Furthermore, in the context, it should be understood that when one element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent the direct orientation but can also be understood as the lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0043] Figure 1 The diagram shows a schematic of the outlet valve provided in this embodiment from one perspective. Figure 2 A schematic diagram of the outlet valve provided in this embodiment is shown from another perspective. (See diagram below.) Figures 1-2 As shown, this embodiment provides a water outlet valve applied to a wall-hung boiler water system. The water outlet valve includes a valve body 1, which has a hot water inlet 111, a heating channel 112, a first interface 1210, a second interface 1220, and a bathroom channel 123. The hot water inlet 111 is connected to the hot water outlet of the combustion chamber of the wall-hung boiler water system, and can selectively connect to either the heating channel 112 or the first interface 1210. Both the first interface 1210 and the second interface 1220 are used to connect to the plate heat exchanger of the wall-hung boiler water system. During operation, when the hot water inlet 111 is connected to the heating channel 112, the hot water in the combustion chamber flows sequentially through the hot water inlet 111 and the heating channel 112 into the heating system to provide heating for the user. The water in the heating system, after heat exchange with the outside environment, can flow back to the combustion chamber through the inlet valve of the wall-hung boiler water system for reheating, thus forming a heating water circulation loop. When the hot water inlet 111 is connected to the first interface 1210, the hot water in the combustion chamber flows through the hot water inlet 111 and the first interface 1210 to the heat exchange channel of the plate heat exchanger to exchange heat with the cold water in the water supply channel of the plate heat exchanger. After the heat exchange, the water in the heat exchange channel can flow back to the combustion chamber through the inlet valve to be reheated, thus forming a heat exchange loop. At the same time, after the cold water in the water supply channel exchanges heat with the hot water in the heat exchange channel, the cold water in the water supply channel becomes warm water, and then flows through the second interface 1220 and the bathroom channel 123 to the bathroom system to provide domestic water for users.

[0044] The above are all water outlet valve solutions proposed in related technologies, and will not be described in detail in this embodiment.

[0045] For ease of narration, such as Figure 1 and Figure 2 As shown, the height direction of the outlet valve after actual installation is defined as the up-down direction. Specifically, the side of the outlet valve closest to the combustion chamber is defined as up, the side facing away from the combustion chamber is defined as down, the side of the outlet valve closest to the plate heat exchanger is defined as rear, and the side facing away from the plate heat exchanger is defined as front. When the user stands facing the outlet valve, the side of the outlet valve facing the user's right hand is defined as right, and the side facing the user's left hand is defined as left. Furthermore, the height direction of valve body 1 refers to the up-down direction, the width direction refers to the left-right direction, and the thickness direction refers to the front-back direction.

[0046] Figure 3 A cross-sectional view of the water outlet valve provided in this embodiment is shown in one direction. Figure 3 and combined Figure 1 , Figure 2As shown, the valve body 1 includes a three-way valve section 11 and a side valve section 12. The side valve section 12 is connected to the second side of the three-way valve section 11. The three-way valve section 11 has a three-way valve chamber 110. The three-way valve chamber 110 includes a first chamber 1102, a main valve chamber 1101, and a second chamber 1103 arranged sequentially along its axial direction. The main valve chamber 1101 is connected to the hot water inlet 111, and the main valve chamber 1101 can selectively connect to the first chamber 1102 or the second chamber 1103. The heating channel 112 is connected to the first chamber 1102. The side valve section 12 has a first flow channel 121, a second flow channel 122, and the aforementioned bathroom channel 123. The first flow channel 121 is used to connect the second chamber 1103 and the first interface 1210, and the second flow channel 122 is used to connect the second interface 1220 and the bathroom channel 123. When the main valve chamber 1101 is connected to the first chamber 1102, the hot water in the combustion chamber 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 can circulate in the heat exchange circulation loop. In this embodiment, the second side of the three-way valve 11 specifically refers to the side of the three-way valve 11 along the left-right direction.

[0047] Optionally, the outlet valve further includes a switching mechanism 3, which is movably disposed in the three-way valve chamber 110 to selectively open 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, thereby realizing three-way switching. The specific structure and working principle of the switching mechanism 3 will not be described in detail in this embodiment. Switching mechanisms applicable to the outlet valve in related technologies to realize three-way switching in the three-way valve chamber are all within the protection scope of this embodiment.

[0048] Furthermore, the outlet valve also includes a drive mechanism 2, the output end of which is connected to a switching mechanism 3 to drive the switching mechanism 3 to move within the three-way valve chamber 110. In this embodiment, the drive mechanism 2 can be a synchronous motor, a stepper motor, a servo motor, or other drive devices.

[0049] Figure 4 A cross-sectional view of the outlet valve provided in this embodiment is shown in another direction. Figure 4 and combined Figure 1As shown, the outlet valve also includes a one-way valve assembly 4, and the valve body 1 also includes a bypass valve section 13, which is connected to the first side of the three-way valve section 11. The bypass valve section 13 has a bypass flow channel 131 and a connecting flow channel 132. The first end 1311 of the bypass flow channel 131 is connected to the main valve chamber 1101, and the two ends of the connecting flow channel 132 are respectively connected to the second end 1312 of the bypass flow channel 131 and the second chamber 1103. The projection of the bypass flow channel 131 on the three-way valve section 11 is located in the area of ​​the three-way valve section 11 where the main valve chamber 1101 is located. The one-way valve assembly 4 is disposed in the bypass flow channel 131 and can selectively open the passage between the bypass flow channel 131 and the main valve chamber 1101 to allow the fluid in the main valve chamber 1101 to flow to the second chamber 1103 through the bypass flow channel 131 and the connecting flow channel 132.

[0050] The outlet valve provided in this embodiment, by providing a bypass flow channel 131 and a connecting flow channel 132 in the bypass valve section 13 that connect the main valve chamber 1101 and the second chamber 1103, can introduce fluid from the main valve chamber 1101 into the second chamber 1103 when the main valve chamber 1101 and the first chamber 1102 are connected, thereby maintaining the system pressure balance. By providing the first end 1311 of the bypass flow channel 131 to be connected to the main valve chamber 1101, and by ensuring that the projection of the bypass flow channel 131 on the three-way valve section 11 is within the area of ​​the three-way valve section 11 where the main valve chamber 1101 is located, the total length of the bypass flow channel 131 and the connecting flow channel 132 can be reduced, shortening the flow path of the fluid from the main valve chamber 1101 to the second chamber 1103, thereby achieving rapid pressure relief of the system and ensuring the safety of the entire wall-hung boiler system. In addition, the one-way valve assembly 4 can also prevent the fluid in the second chamber 1103 from flowing into the main valve chamber 1101, thus affecting the performance of the outlet valve.

[0051] like Figure 4 As shown, the axial direction of the bypass channel 131 is perpendicular to the axial direction of the main valve chamber 1101. This design, on the one hand, minimizes water resistance when fluid flows from the main valve chamber 1101 into the bypass channel 131, thereby increasing the fluid velocity; on the other hand, it facilitates the machining of the bypass channel 131 and the installation of the one-way valve assembly 4 within it. Of course, this embodiment does not limit the specific value of the angle between the axial direction of the bypass channel 131 and the axial direction of the main valve chamber 1101; designers can adapt it according to actual machining requirements.

[0052] Optionally, the angle between the axis of the connecting flow channel 132 and the axis of the bypass flow channel 131 is less than or equal to 45°. It is understood that the axes of the bypass flow channel 131, the connecting flow channel 132, and the main valve chamber 1101 intersect each other to form a right triangle. According to the principle of right triangles, the smaller the angle between the axes of the connecting flow channel 132 and the bypass flow channel 131, the shorter the extension length of the connecting flow channel 132 (i.e., the length of the hypotenuse of the aforementioned right triangle). Therefore, this arrangement can further shorten the length of the connecting flow channel 132, thereby shortening the flow path of the fluid from the main valve chamber 1101 to the second chamber 1103, thus achieving rapid pressure relief of the system and ensuring the safety of the entire wall-hung boiler system. For example, the angle between the axial direction of the connecting channel 132 and the axial direction of the bypass channel 131 can be 30°, 32°, 35°, 36°, 38°, 40°, 42°, 44°, 45°, etc. Of course, the specific value of the angle between the axial direction of the connecting channel 132 and the axial direction of the bypass channel 131 in this embodiment is not limited to the above values, and designers can also make adaptive adjustments according to actual processing requirements.

[0053] like Figure 1 and Figure 4 As shown, the bypass valve section 13 is also provided with a bypass port 1313 communicating with the bypass flow channel 131, and a plug 133 is detachably connected to the bypass port 1313. When the check valve assembly 4 malfunctions, the operator can remove the plug 133 from the bypass port 1313 to facilitate maintenance of the check valve assembly 4; in addition, the plug 133 can also limit the movement of the check valve assembly 4 to improve the installation stability of the check valve assembly 4. It should be noted that the check valve assembly 4 is prior art, and the specific structure and working principle of the check valve assembly 4 will not be described in detail in this embodiment.

[0054] Optionally, a first sealing element 61 is further provided between the sealing element 133 and the bypass port 1313 to ensure a sealed installation between the sealing element 133 and the bypass port 1313, thereby preventing fluid in the bypass channel 131 or the connecting channel 132 from leaking from the bypass port 1313. In this embodiment, the first sealing element 61 is a rubber ring, which has a good sealing effect and low cost.

[0055] Figure 5 A schematic diagram of the valve body 1 provided in this embodiment is shown. Figure 5 and combined Figures 1-3As shown, the water outlet valve also includes a water replenishment component 5, and the side valve part 12 also has a water replenishment channel 124. The two ends of the water replenishment channel 124 are respectively connected to the bathroom channel 123 and the main valve chamber 1101. The water replenishment component 5 includes a water replenishment valve core 52 that is movably disposed in the path of the water replenishment channel 124. The water replenishment valve core 52 can selectively open or cut off the water replenishment channel 124. By providing a water supply channel 124 within the side valve section 12 and a water supply valve core 52 on the side valve section 12 that can selectively open or cut off the water supply channel 124, fluid from the bathroom passage 123 can be introduced into the main valve chamber 1101 when the heating water circuit is short of water, thus avoiding dry burning caused by water shortage in the heating water circuit and ensuring the safety of the entire wall-hung boiler system. Compared to the related technology where the water supply component is placed on the inlet valve, placing the water supply component 5 on the valve body 1 of the outlet valve also ensures that the fluid introduced into the main valve chamber 1101 from the bathroom passage 123 is a higher temperature fluid, thereby avoiding the rapid drop in the temperature of the fluid in the heating water circuit caused by the flow of lower temperature fluid into the heating water circuit, which would affect the service life of other components in the wall-hung boiler system.

[0056] Optionally, such as Figure 1 As shown, the water supply channel 124 includes a first branch channel 1241 and a second branch channel 1242 that are angled together and interconnected. One end of the first branch channel 1241 is connected to the bathroom channel 123, and one end of the second branch channel 1242 is connected to the main valve chamber 1101. The water supply valve core 52 is movably disposed at the connection between the first branch channel 1241 and the second branch channel 1242. By setting the water supply channel 124 as an angled first branch channel 1241 and second branch channel 1242, the processing of the water supply channel 124 can be facilitated, the processing difficulty reduced, and the processing efficiency improved.

[0057] Figure 6 A cross-sectional schematic diagram of the water replenishment component 5 provided in this embodiment is shown. Figure 6 and combined Figure 1 , Figure 3 , Figure 5 As shown, a water supply port 1240 is formed within the water supply channel 124. The water supply assembly 5 also includes a water supply sleeve 51, which is sealed to the side valve portion 12. A water supply valve core 52 is movably disposed within the water supply sleeve 51 along its axial direction, with one end of the valve core 52 extending into the water supply channel 124 and sealingly engaging with the water supply port 1240. When the water supply valve core 52 moves axially along the water supply sleeve 51, it can move closer to or further away from the water supply port 1240 to open or seal the port, thereby enabling the opening and shut-off of the water supply channel 124.

[0058] In this embodiment, the water supply connection port 1240 is formed at the connection between the first branch channel 1241 and the second branch channel 1242. This design can simplify the processing technology of the water supply channel 124, and it is not necessary to process the water supply connection port 1240 at other locations of the water supply channel 124, thereby improving the processing efficiency to a certain extent.

[0059] In this embodiment, the water supply valve core 52 is threadedly connected to the water supply sleeve 51. When the water supply valve core 52 is rotated, it can move along the axial direction of the water supply sleeve 51 at the same time. The structure is simple, easy to assemble, and convenient to operate.

[0060] Optionally, a second sealing element 62 is provided at one end of the water supply valve core 52 that extends into the water supply channel 124. When the water supply valve core 52 abuts against the water supply connection port 1240, the second sealing element 62 can be pressed between the water supply valve core 52 and the water supply connection port 1240, thereby improving the sealing effect between the water supply valve core 52 and the water supply connection port 1240, and preventing fluid in the bathroom passage 123 from flowing into the main valve chamber 1101 through the water supply channel 124 when water is not needed to replenish the heating water circuit. In this embodiment, the second sealing element 62 is a rubber ring, which has a good sealing effect and low cost.

[0061] Optionally, a third sealing element 63 is provided between the water supply sleeve 51 and the water supply valve core 52 to ensure the sealing performance between them. This prevents fluid in the water supply channel 124 from leaking through the gap between the water supply sleeve 51 and the water supply valve core 52, thereby ensuring the safety of the outlet valve. The third sealing element 63 is a rubber ring, which provides a good seal and is relatively inexpensive. In this embodiment, two third sealing elements 63 are used to further ensure a good seal between the water supply sleeve 51 and the water supply valve core 52. Of course, in other embodiments, the number of third sealing elements 63 can be one, three, four, or even more; this embodiment does not limit this.

[0062] like Figure 6 As shown, the water replenishment component 5 also includes a drive member 53. The other end of the water replenishment valve core 52 extends out of the water replenishment sleeve 51 and is connected to the output end of the drive member 53. The drive member 53 can drive the water replenishment valve core 52 to move axially along the water replenishment sleeve 51. In this embodiment, the drive member 53 is used to drive the water replenishment valve core 52 to rotate, thereby causing it to move axially along the water replenishment sleeve 51, so that the end of the water replenishment valve core 52 extending into the water replenishment channel 124 approaches or moves away from the water replenishment connection port 1240.

[0063] In this embodiment, the driving component 53 is a handwheel, that is, the water supply component 5 is a manual water supply valve. When water needs to be supplied to the heating water circuit, the operator can manually turn the handwheel to drive the water supply valve core 52 to rotate, thereby opening the water supply connection port 1240; after water supply is completed, the operator can also turn the handwheel in the opposite direction to drive the water supply valve core 52 to rotate in the opposite direction, thereby blocking the water supply connection port 1240.

[0064] Of course, in other embodiments, the drive unit 53 can also be configured as an automatic drive to automatically open the water supply channel 124 when the heating water circuit is short of water, thereby improving the automated water supply operation of the wall-hung boiler system. This embodiment does not limit the specific structure of the automatic drive, which can be a drive device such as a drive motor that can realize the rotation of the water supply valve core 52.

[0065] like Figure 5 As shown, in this embodiment, the valve body 1 is a one-piece molded structure, which simplifies the processing technology, reduces leakage points on the valve body 1, and thus ensures the safety of the entire outlet valve.

[0066] Continue as Figure 1 and Figure 2 As shown, in this embodiment, the bypass valve 13 and the water supply component 5 are respectively disposed on both sides of the valve body 1 along the front-rear direction. This design, on the one hand, makes full use of the installation space on the valve body 1, improving the structural compactness of the outlet valve; on the other hand, it avoids interference between the water supply channel 124 and the bypass channel 131 during processing when the bypass valve 13 and the water supply component 5 are installed on the same side of the valve body 1, thus avoiding increasing the processing difficulty of the valve body 1. It is understood that, to facilitate manual adjustment of the water supply component 5 by the operator, in this embodiment, the water supply component 5 is disposed on the front side of the valve body 1, and the bypass valve 13 is disposed on the rear side of the valve body 1. Of course, this embodiment is not limited to this, and the designer can also make adaptive adjustments to the installation positions of the bypass valve 13 and the water supply component 5 on the valve body 1 according to actual installation and usage requirements.

[0067] 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.
