Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular 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] like Figure 1 As shown, in the related technology, the three-way valve chamber 110' of the outlet valve and the heating channel 120' are coaxially arranged, and during installation, the axis of the three-way valve chamber 110' extends in the vertical direction. The top of the three-way valve chamber 110' also needs to install a drive motor, which results in a large size of the entire outlet valve in the height direction. Consequently, the installation height of the entire wall-hung boiler water circuit system is high and the volume is large, which cannot meet the market demand for miniaturization of the wall-hung boiler water circuit system. In addition, a bypass valve section 12' is provided on the side of the three-way valve section 11' of the outlet valve. The bypass valve section 12' has a bypass cavity for installing a one-way valve 20'. One end of the bypass cavity is connected to the heating channel 120', and the other end is connected to the heat exchange channel through the three-way valve cavity 110'. When the one-way valve 20' is opened, water in the heating channel 120' can be supplied to the heat exchange structure through the bypass cavity and the heat exchange channel. However, the height of the outlet side of the one-way valve 20' is slightly higher than the height of the connection between the bypass cavity and the three-way valve cavity 110'. Therefore, if... Figure 1 As indicated by the middle arrow, when the check valve 20' is opened, the water in the heating channel 120' flows from the inlet side of the check valve 20' to its outlet side. The water on the outlet side then flows downwards into the three-way valve chamber 110', causing a "backflow" phenomenon in some of the water flow. Consequently, when the outlet valve is in actual operation, the fully open flow loss of the check valve 20' is significant, affecting the water replenishment efficiency.

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

[0005] 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, can significantly reduce the height dimension of the three-way valve, thereby meeting the miniaturization requirements of the entire wall-hung boiler water system; on the other hand, it can also reduce the flow loss of the fully open one-way valve and improve water replenishment efficiency.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A water outlet valve includes a valve body and a check valve, wherein the valve body includes a main valve section and a side valve section;

[0008] The main valve section has a three-way valve chamber, a heating interface, a first connecting channel, and a bypass chamber. The three-way valve chamber includes a first chamber, a main valve chamber, and a second chamber that are sequentially connected along a first direction. The main valve chamber can be selectively connected to either the first chamber or the second chamber. The heating interface is connected to the first chamber through the first connecting channel. The first end of the bypass chamber is connected to the first chamber through the first connecting channel. The second end of the bypass chamber is connected to the second chamber. The axial direction of the bypass chamber extends along a second direction.

[0009] The side valve is connected to the main valve on one side along the third direction, and a first flow channel communicating with the second cavity is provided in the side valve.

[0010] The one-way valve is installed in the bypass cavity to allow fluid in the first cavity to flow through the bypass cavity to the second cavity only, and the angle between the axial direction of the one-way valve and the flow direction of the fluid from the outlet side of the one-way valve to the second cavity is greater than 90°.

[0011] The first direction, the second direction, and the third direction are set at an angle to each other.

[0012] As a preferred embodiment of the outlet valve provided by this utility model, the main valve section includes:

[0013] A three-way valve section, wherein the three-way valve chamber is formed within the three-way valve section;

[0014] The heating valve section is connected below the three-way valve section. The heating interface, the first connecting channel and the bypass cavity are all provided on the heating valve section. A bypass port connected to the bypass cavity is provided on the front side of the heating valve section. A bypass plug is detachably connected to the bypass port.

[0015] As a preferred embodiment of the water outlet valve provided by this utility model, the heating valve section is provided with a first processing channel, a second processing channel and a third processing channel. The first processing channel is located below the first cavity and is connected to the first cavity; the second processing channel is located below the second cavity and is connected to the second cavity, and a portion of the second processing channel forms the bypass cavity; the two ends of the third processing channel are respectively connected to the first processing channel and the second processing channel.

[0016] The first processing channel extends downward and penetrates the valve body to form a first processing hole on the valve body, and the second processing channel extends downward and penetrates the valve body to form a second processing hole on the valve body. Both the first processing hole and the second processing hole can serve as the heating interface.

[0017] A portion of the first processing channel is connected to the third processing channel to form the first connecting channel.

[0018] As a preferred embodiment of the water outlet valve provided by this utility model, the axial direction of the first processing channel is parallel to the axial direction of the second processing channel and both are perpendicular to the first direction, and the axial direction of the third processing channel is parallel to the first direction.

[0019] As a preferred embodiment of the outlet valve provided by this utility model, a first limiting structure is provided on the inner side of the bypass plug, and the bottom end of the one-way valve abuts against the first limiting structure.

[0020] As a preferred embodiment of the outlet valve provided by this utility model, a second limiting structure is provided on the cavity wall of the bypass cavity near the second cavity, and the top of the one-way valve abuts against the second limiting structure.

[0021] As a preferred embodiment of the water outlet valve provided by this utility model, a second connecting channel is also provided in the side valve section, and the two ends of the second connecting channel are respectively perpendicularly connected to the second cavity and the first flow channel.

[0022] As a preferred embodiment of the water outlet valve provided by this utility model, the second connecting channel extends through the valve body along its axial direction to the side opposite to the main valve part, so as to form a third machining hole on the valve body, and a first sealing member is detachably connected to the third machining hole.

[0023] As a preferred embodiment of the water outlet valve provided by this utility model, the water outlet valve further includes:

[0024] A switching mechanism is movably disposed in the three-way valve chamber to selectively open the passage between the main valve chamber and the first chamber or the passage between the main valve chamber and the second chamber;

[0025] A drive mechanism is located on the front side of the main valve section. The output end of the drive mechanism is connected to the switching mechanism to drive the switching mechanism to move within the three-way valve chamber.

[0026] As a preferred embodiment of the water outlet valve provided by this utility model, the top of the main valve section is also provided with a hot water inlet that communicates with the main valve cavity.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model provides a water outlet valve. Compared with the prior art where the three-way valve chamber and the heating channel are coaxially arranged, this water outlet valve can set the three-way valve chamber and the heating channel in two different directions, so as to avoid 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 and reducing the installation height of the wall-hung boiler water circuit system. By setting a bypass valve, water in the heating channel can be selectively led to the first flow channel to distribute water to the heat exchange structure, avoiding damage to the heat exchange structure due to dry burning due to lack of water. By installing the bypass valve in the bypass cavity between the heating channel and the second cavity, the bypass valve part set on the valve body in the prior art can be omitted, thereby reducing the size of the water outlet valve in the thickness direction, simplifying the manufacturing process, reducing material usage, reducing material costs, and thus meeting the miniaturization requirements of the entire wall-hung boiler water circuit system.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] Figure 2 One of the structural schematic diagrams of the water outlet valve 100 provided in this embodiment is shown. Figure 3 The second schematic diagram of the structure of the water outlet valve 100 provided in this embodiment is shown. Figure 4 One of the cross-sectional views of the outlet valve 100 provided in this embodiment is shown. For example... Figures 2-4As shown, this embodiment provides a water outlet valve 100, which is applied to the water circuit system of a wall-hung boiler. The water outlet valve 100 includes a valve body 1, which has a hot water inlet 111, a heating interface first flow channel 131, a second flow channel 132, and a bathroom passage 133. The hot water inlet 111 is connected to the hot water outlet of the combustion chamber of the wall-hung boiler water circuit system, and the hot water inlet 111 can selectively connect to the heating interface or the first flow channel 131. The first flow channel 131 and the second flow channel 132 are both used to connect to the heat exchange structure of the wall-hung boiler water circuit system. During operation, when the hot water inlet 111 is connected to the heating interface, the hot water in the combustion chamber flows sequentially through the hot water inlet 111 and the heating interface into the heating system to provide heating for users. The water in the heating system, after exchanging heat with the outside, can flow back to the combustion chamber through the inlet valve of the wall-mounted boiler water circuit system to be reheated, thus forming a heating water circulation loop. When the hot water inlet 111 is connected to the first flow channel 131, the hot water in the combustion chamber flows sequentially through the hot water inlet 111 and the first flow channel 131 into the heat exchange channel of the heat exchange structure to exchange heat with the cold water in the supply channel of the heat exchange structure. After 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 circulation loop. In addition, after the cold water in the supply channel exchanges heat with the hot water in the heat exchange channel, the cold water in the supply channel becomes warm water, and then flows sequentially through the second flow channel 132 and the bathroom channel 133 into the bathroom system to provide domestic water for users.

[0052] Of course, in other embodiments, the valve body 1 of the outlet valve 100 may not be provided with the second flow channel 132 and the bathroom channel 133. The outlet end of the first flow channel 131 is directly connected to the bathroom system. That is, when the hot water inlet 111 is connected to the first flow channel 131, the hot water in the combustion chamber can flow into the bathroom system through the hot water inlet 111 and the first flow channel 131 in sequence to provide domestic water for users.

[0053] The above are all existing technologies, and will not be described in detail in this embodiment.

[0054] In related technologies, water outlet valves are often installed at a relatively high height. To address this issue, in this embodiment, the valve body 1 includes a main valve section 10 and a side valve section 13. The main valve section 10 includes a three-way valve section 11 and a heating valve section 12. The three-way valve section 11 has a three-way valve chamber 110, which 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 can selectively communicate with either the first chamber 1102 or the second chamber 1103. The heating valve section 12 is connected to one side of the three-way valve section 11 along a second direction, and a heating interface is provided on the heating valve section 12. The side valve section 13 is connected to one side of the main valve section 10 along a third direction, and a first flow channel 131, a second flow channel 132, and a bathroom channel 133 are all located within the side valve section 13. The first direction, the second direction, and the third direction are arranged at an angle to each other. This design allows the entire structural dimensions of the valve body 1 to be distributed across three directions in three-dimensional space at angles to each other, thus avoiding excessive length of the valve body 1 along the axis of the three-way valve chamber 110. This optimizes the spatial layout of the entire outlet valve 100 and meets the miniaturization requirements of the wall-hung boiler water system.

[0055] The hot water inlet 111 is located on the three-way valve section 11 and is connected to the main valve chamber 1101. The hot water inlet 111 is selectively connected to either the first chamber 1102 or the second chamber 1103 via the main valve chamber 1101. Optionally, the hot water inlet 111 is located at the top of the three-way valve section 11, allowing the connecting pipe between the hot water outlet and the hot water inlet 111 to be manufactured as a straight pipe structure, avoiding excessive bends and thus preventing excessive water resistance caused by excessive bends in the connecting pipe.

[0056] It needs to be explained that, such as Figure 2 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 is defined as up, the side of the outlet valve 100 away from the combustion chamber is defined as down, the side of the outlet valve 100 closest to the heat exchange structure is defined as rear, and the side of the outlet valve 100 away from the heat exchange structure 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. In this embodiment, the first direction specifically refers to the front-back direction, the second direction specifically refers to the up-down direction, and the third direction specifically refers to the left-right direction.

[0057] In other words, in this embodiment, the three-way valve section 11 (three-way valve chamber 110) 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 side valve section 13 is connected to the right side of the three-way valve section 11, making the entire valve body 1 roughly square in shape. This fully utilizes 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 system and optimizing the spatial layout of the entire system. Of course, in other embodiments, the side valve section 13 can also be connected to the left side of the three-way valve section 11.

[0058] like Figure 3 and Figure 4 As shown, the outlet valve 100 also includes a switching mechanism 3, which is movably disposed within 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. When the switching mechanism 3 opens the passage between the main valve chamber 1101 and the first chamber 1102, the hot water in the combustion chamber can circulate in the heating water circulation loop; when the switching mechanism 3 opens the passage between the main valve chamber 1101 and the second chamber 1103, the hot water in the combustion chamber 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 or meet the user's heating needs.

[0059] Figure 5 The third schematic diagram of the structure of the water outlet valve 100 provided in this embodiment is shown. Figure 5 and combined Figure 4 As shown, the outlet valve 100 also includes a drive mechanism 2. The output end of the drive mechanism 2 is connected to the switching mechanism 3 to drive the switching mechanism 3 to move along the axial direction of the three-way valve chamber 110. In this embodiment, the drive mechanism 2 is a stepper motor, which has advantages such as high control precision, fast response speed and high reliability.

[0060] It is worth noting that by arranging the three-way valve section 11 in the front-rear direction, the drive mechanism 2 can also be installed on the front side of the valve body 1 to avoid the gap area between the valve body 1 and the combustion chamber, 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, and reduce the height of the entire wall-hung boiler water circuit system.

[0061] Figure 6 A second cross-sectional view of the outlet valve 100 provided in this embodiment is shown. (See attached image.) Figure 6 As shown, in other embodiments, the drive mechanism 2 can also be a synchronous motor, which has advantages such as constant speed, good operating stability, high efficiency, small size, light weight and low material consumption.

[0062] like Figure 4 and Figure 6As shown, the outlet valve 100 also includes a one-way valve 4. The heating valve section 12 also has a first connecting channel and a bypass cavity 1221. The heating interface is connected to the first cavity 1102 through the first connecting channel. The first end of the bypass cavity 1221 is connected to the first cavity 1102 through the first connecting channel, and the second end of the bypass cavity 1221 is connected to the second cavity 1103. The one-way valve 4 is installed in the bypass cavity 1221 so that only the fluid in the first cavity 1102 is allowed to flow to the second cavity 1103 through the bypass cavity 1221. The angle between the axial direction of the one-way valve 4 and the flow direction of the fluid from the outlet side of the one-way valve 4 to the second cavity 1103 is greater than 90°. By providing a bypass cavity 1221 within the heating valve section 12 and a one-way valve 4 within the bypass cavity 1221, water in the first cavity 1102 can be selectively diverted to the first flow channel 131 to replenish water for the heat exchange structure, preventing damage to the heat exchange structure due to dry burning. Furthermore, by setting the angle between the axis of the one-way valve 4 and the flow direction of the fluid from the outlet side of the one-way valve 4 to the second cavity 1103 to be greater than 90°, compared to… Figure 1 In the proposed scheme, the fluid flowing from the outlet side of the check valve 4 to the second chamber 1103 will not experience "backflow," thereby effectively reducing the flow loss when the check valve 4 is fully open, and thus ensuring the water replenishment effect of the entire outlet valve 100.

[0063] It should be explained that the calculation method for the fully open flow loss of the check valve 4 is as follows: First, test the fully open flow L0 of a single check valve 4. Then, install the check valve 4 onto the valve body 1 and test the fully open flow L1 of the check valve 4 at this time. The fully open flow loss of the check valve 4 is then L1 / L0. It should be noted that the check valve 4 is a commonly used valve structure in this field, and the specific structure and working principle of the check valve will not be described in detail in this embodiment.

[0064] Optionally, a bypass port 1223 communicating with the bypass cavity 1221 is also provided on the front side of the heating valve section 12. A bypass plug 5 is detachably connected to the bypass port 1223, so that the operator can perform maintenance on the one-way valve 4 by simply opening the bypass plug 5. Moreover, the bypass port 1223 is located on the front side of the heating valve section 12, and the operator can operate it while standing facing the wall-hung boiler water system without having to remove the entire outlet valve 100, making the operation convenient and easy.

[0065] Figure 7 A schematic diagram of the bypass plug 5 provided in this embodiment is shown. Figure 7 and combined Figure 4 , Figure 6As shown, a first limiting structure 51 is provided on the inner side of the bypass plug 5, and the bottom end of the one-way valve 4 abuts against the first limiting structure 51. By setting the first limiting structure 51, the one-way valve 4 can be limited to avoid displacement relative to the heating valve section 12 under its own gravity, which would affect the performance of the entire outlet valve 100.

[0066] Optionally, a second limiting structure 1222 is provided on the cavity wall of the bypass cavity 1221 near the second cavity 1103, and the top of the check valve 4 abuts against the second limiting structure 1222. By providing the second limiting structure 1222, the installation height of the check valve 4 can be limited, which on the one hand ensures the normal use of the outlet valve 100, and on the other hand facilitates the operator to repair the check valve 4 from the bypass port 1223 when a malfunction occurs.

[0067] Figure 8 This is shown as a third cross-sectional view of the outlet valve 100 provided in this embodiment. (See diagram below.) Figure 8 and combined Figure 4 As shown, the heating valve section 12 has a first processing channel 121, a second processing channel 122, and a third processing channel 123. The first processing channel 121 is located below and connected to the first cavity 1102. The second processing channel 122 is located below and connected to the second cavity 1103. A portion of the second processing channel 122 forms the bypass cavity 1221. The two ends of the third processing channel 123 are connected to the first processing channel 121 and the second processing channel 122, respectively. The first processing channel 121 extends downward and penetrates the valve body 1 to form a first processing hole 1210 on the valve body 1. The second processing channel 122 extends downward and penetrates the valve body 1 to form a second processing hole 1220 on the valve body 1. Both the first processing hole 1210 and the second processing hole 1220 can serve as the heating interface. A portion of the first processing channel 121 is connected to the third processing channel 123 to form the first connecting channel.

[0068] In some embodiments, such as Figure 4 As shown, the second machining hole 1220 serves as the aforementioned heating interface. Specifically, the portion of the second machining channel 122 near the second cavity 1103 forms a bypass cavity 1221, while the portion of the second machining channel 122 away from the second cavity 1103 forms the heating interface. At this time, a second sealing element 62 is used to seal the first machining hole 1210 to prevent fluid leakage inside the valve body 1. In other embodiments, such as... Figure 8As shown, the first machining hole 1210 serves as the aforementioned heating interface, and the second machining hole 1220 is sealed with a second sealing element 62 to prevent fluid leakage inside the valve body 1. With the above configuration, operators can selectively connect the first machining hole 1210 or the second machining hole 1220 to the heating system according to the installation requirements of different wall-hung boiler water systems, thereby improving the versatility of the outlet valve 100.

[0069] Optionally, the axial direction of the first processing channel 121 is parallel to the axial direction of the second processing channel 122, and both are perpendicular to the first direction, while the axial direction of the third processing channel 123 is parallel to the first direction. That is, the first processing channel 121 and the second processing channel 122 both extend in the vertical direction, while the third processing channel 123 extends in the front-back direction. This design facilitates demolding during the processing of the valve body 1.

[0070] Figure 9 This is shown as a fourth cross-sectional view of the outlet valve 100 provided in this embodiment. Figure 9 and combined Figure 3 As shown, a second connecting channel 134 is also provided inside the side valve section 13. The two ends of the second connecting channel 134 are perpendicularly connected to the second cavity 1103 and the first flow channel 131, respectively. Specifically, the second connecting channel 134 extends through the valve body 1 along its axial direction to the side opposite to the main valve section 10, so as to form a third machining hole 1341 on the valve body 1. A first sealing member 61 is detachably connected to the third machining hole 1341. By providing the first sealing member 61 at the third machining hole 1341, fluid leakage inside the valve body 1 can be avoided, and the above arrangement can facilitate demolding during the processing of the valve body 1.

[0071] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
