Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a flow regulating 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 of water flow, thereby ensuring the even distribution of hot water within the pipes and the proper heating of the radiators.

[0003] However, due to the limitations of the overall water circuit system of the wall-hung boiler, most of the outlet valves in related technologies have a constant flow rate, meaning the fluid flow rate at the bathroom outlet of the outlet valve is constant. To adjust the flow rate at the bathroom outlet of the outlet valve to meet the needs of different users, a flow regulating valve is usually installed on the main body of the outlet valve in these technologies. The flow regulating valve typically includes independent inlet and outlet branch pipes. The main body of the outlet valve needs to be equipped with an inlet interface for installing the inlet branch pipe and an outlet interface for installing the outlet branch pipe, resulting in a large overall size, complex structure, low processing efficiency, and high processing costs for the outlet valve.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0040] Figure 1 A schematic diagram of the flow regulating valve provided in this embodiment is shown. Figure 2 A front view of the flow regulating valve provided in this embodiment is shown. Figure 3 It shows Figure 2 A schematic diagram of the cross-sectional structure at point AA. (See diagram below.) Figures 1-3As shown, this embodiment provides a flow regulating valve, which includes a valve body 1 and a drive component 2. The valve body 1 has a first inlet / outlet water channel 111, a second inlet / outlet water channel 121, and a connecting port 112 that connects the first inlet / outlet water channel 111 and the second inlet / outlet water channel 121. The second inlet / outlet water channel 121 is arranged around the first inlet / outlet water channel 111. The drive component 2 is mounted on the valve body 1. The output end of the drive component 2 is provided with a blocking part 2121. The blocking part 2121 is located inside the valve body 1, and the drive component 2 can drive the blocking part 2121 to move closer to or away from the connecting port 112 to adjust the distance between the blocking part 2121 and the connecting port 112.

[0041] The flow regulating valve provided in this embodiment, by setting a first inlet / outlet channel 111 and a second inlet / outlet channel 121 surrounding the first inlet / outlet channel 111 inside the valve body 1, allows the operator to simultaneously form the first inlet / outlet channel 111 and the second inlet / outlet channel 121 for water inlet and outlet respectively in a pipeline facing the same direction during processing. This simplifies the structure of the entire flow regulating valve, reduces its overall size, improves processing efficiency, and reduces processing costs. By setting a driving component 2 and a blocking part 2121 at the output end of the driving component 2, when the driving component 2 is activated, it can drive the blocking part 2121 to move closer to or away from the connecting port 112, thereby adjusting the distance between the blocking part 2121 and the connecting port 112, and thus realizing the adjustment of the water flow between the first inlet / outlet channel 111 and the second inlet / outlet channel 121 to meet different water consumption needs and improve the user experience.

[0042] Specifically, in use, one of the first inlet / outlet channel 111 and the second inlet / outlet channel 121 is the inlet channel, and the other is the outlet channel. The flow diameter of the inlet channel is smaller than that of the outlet channel, thereby reducing the water resistance in the outlet channel and improving the water output efficiency. In this embodiment, the first inlet / outlet channel 111 serves as the inlet channel, and the second inlet / outlet channel 121 serves as the outlet channel. Of course, in other embodiments, the first inlet / outlet channel 111 can also be configured as the outlet channel, and the second inlet / outlet channel 121 as the inlet channel. For ease of description, this embodiment uses "the first inlet / outlet channel 111 as the inlet channel and the second inlet / outlet channel 121 as the outlet channel" as an example to describe the specific structure of the flow regulating valve in detail.

[0043] Figure 4 A schematic diagram of the valve body 1 provided in this embodiment is shown from one perspective. Figure 5 A schematic diagram of the valve body 1 provided in this embodiment is shown from another perspective. For example... Figures 4-5 and combined Figure 3As shown, the valve body 1 includes a main valve section 13, a first inlet / outlet branch pipe 11, and a second inlet / outlet branch pipe 12. A water passage chamber 131 is formed inside the main valve section 13. The second inlet / outlet branch pipe 12 is connected to the main valve section 13. At least a portion of the first inlet / outlet branch pipe 11 is inserted into the second inlet / outlet branch pipe 12. A first inlet / outlet channel 111 is formed inside the first inlet / outlet branch pipe 11. The second inlet / outlet channel 121 is formed between the outer wall of the first inlet / outlet branch pipe 11 and the inner wall of the second inlet / outlet branch pipe 12. Both the first inlet / outlet channel 111 and the second inlet / outlet channel 121 can be connected to the water passage chamber 131 through the connecting port 112.

[0044] In practical applications, the driving component 2 can drive the blocking part 2121 to move between a first position and a second position. When the blocking part 2121 is in the first position, its outer contour can completely cover the connecting port 112, so that the minimum water flow through the connecting port 112 can be close to 0, thereby increasing the adjustment range of the water flow. When the blocking part 2121 is in the second position, the distance between the blocking part 2121 and the connecting port 112 is the maximum, so that the water flow through the connecting port 112 is the maximum. In this embodiment, the driving component 2 can drive the blocking part 2121 to move to any position between the first position and the second position, so that the water flow through the connecting port 112 can be adjusted between the minimum and maximum values. This embodiment does not limit the maximum distance between the blocking part 2121 and the connecting port 112; designers can make adaptive adjustments according to actual needs. Specifically, refer to... Figure 3 The dashed arrow indicates that when the blocking part 2121 moves to any position between the first position and the second position, that is, when the connecting port 112 is opened, water in the first inlet / outlet channel 111 can flow through the connecting port 112 into the water passage 131, and then flow out from the second inlet / outlet channel 121. In this embodiment, the opening of the first inlet / outlet branch pipe 11 near the blocking part 2121 forms the aforementioned connecting port 112. That is, when the blocking part 2121 is in the first position, it blocks the opening of the first inlet / outlet channel 111.

[0045] Optionally, such as Figure 1 and Figure 2 As shown, the axes of the first inlet / outlet branch pipe 11 and the second inlet / outlet branch pipe 12 do not coincide. If this flow regulating valve is applied to an outlet valve, it can be used as follows: Figure 2When installed in the direction shown, even if the axis of the first inlet / outlet branch pipe 11 and the axis of the second inlet / outlet branch pipe 12 are in the same vertical plane, and the axis of the first inlet / outlet branch pipe 11 is above the axis of the second inlet / outlet branch pipe 12, this installation method can make the distance between the inner wall of the second inlet / outlet channel 121 and the outer wall of the first inlet / outlet channel 111 gradually increase from top to bottom, in order to adapt to the flow pattern in which most of the water in the second inlet / outlet channel 121 gathers at the bottom of the second inlet / outlet channel 121 due to gravity, thereby improving the water flow efficiency in the second inlet / outlet channel 121.

[0046] In this embodiment, the distance L between the axis of the first inlet / outlet branch pipe 11 and the axis of the second inlet / outlet branch pipe 12 is 0.1mm to 10mm. For example, L can be 0.2mm, 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, etc. Designers can adjust the specific value of L according to actual usage requirements; this embodiment does not limit this.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, a portion of the outer wall of the first inlet / outlet branch pipe 11 is in contact with the inner wall of the second inlet / outlet branch pipe 12. This arrangement maximizes the eccentricity between the first inlet / outlet branch pipe 11 and the second inlet / outlet branch pipe 12, further ensuring high flow efficiency of water within the second inlet / outlet channel 121. Furthermore, it facilitates the fixing of the first inlet / outlet branch pipe 11, allowing it to be directly and securely connected to the second inlet / outlet branch pipe 12 without the need for additional supports. This simplifies the manufacturing process and reduces material costs to some extent.

[0048] like Figure 3 As shown, the driving component 2 includes a servo motor 21, which includes a motor body 211 and a regulating valve core 212 connected to the motor body 211. The side wall portion of the regulating valve core 212 protrudes outward to form the aforementioned sealing portion 2121. Because the servo motor 21 has advantages such as high precision, stable operation, high reliability, and ease of maintenance, it can achieve precise adjustment of the water flow between the first inlet / outlet channel 111 and the second inlet / outlet channel 121.

[0049] Furthermore, the drive component 2 also includes a support sleeve 22, and the valve body 1 is provided with a mounting port 132 for installing the drive component 2. The support sleeve 22 is sealed to the mounting port 132, and the regulating valve core 212 passes through the support sleeve 22 and the two are threadedly connected. When the motor body 211 is started, it can drive the regulating valve core 212 to rotate, thereby causing the sealing part 2121 to move along the axial direction of the regulating valve core 212 to move closer to or away from the communication port 112. By providing the support sleeve 22, its transmission support for the regulating valve core 212 can be increased.

[0050] Specifically, the support sleeve 22 includes a transmission engagement part 221 and an inner sealing part 222 connected to each other. The transmission engagement part 221 is threadedly engaged with the regulating valve core 212. The inner sealing part 222 is sleeved on the outer periphery of the regulating valve core 212, and a first sealing element 231 is provided between the inner sealing part 222 and the regulating valve core 212 to ensure the sealing between the transmission part of the regulating valve core 212 and the area through which water flows in the valve body 1. Optionally, a second sealing element 232 is also provided between the transmission engagement part 221 and the mounting port 132 to enhance the sealing between the servo motor 21 and the area through which water flows in the valve body 1, thereby protecting the power component. In this embodiment, both the first sealing element 231 and the second sealing element 232 can be O-rings, and the number of layers of O-rings is not limited. For example, the first sealing element 231 can be configured with one, two, three, or even more layers.

[0051] Optionally, the support sleeve 22 is provided with a limiting part that abuts against the blocking part 2121. The limiting part is used to limit the maximum distance of the blocking part 2121 from the communication port 112. That is, when the blocking part 2121 is in the second position, the blocking part 2121 abuts against the limiting part of the support sleeve 22, so that the maximum opening of the blocking part 2121 is limited by the position of the limiting part, thereby facilitating the determination of the maximum value of the water flow. When designing this flow regulating valve, the maximum opening of the blocking part 2121 can be changed by changing the length of the inner sealing part 222, thereby changing the adjustment range of the water flow. In this embodiment, the free end of the inner sealing part 222 of the support sleeve 22 forms the aforementioned limiting part.

[0052] like Figure 3 and Figure 5 As shown, a guide groove 133 is also provided inside the valve body 1 (specifically the main valve part 13), and the end of the regulating valve core 212 facing away from the motor body 211 slides through the guide groove 133. When the motor body 211 drives the regulating valve core 212 to move, the regulating valve core 212 can be guided and limited by the guide groove 133 to ensure the stability of the regulating valve core 212 during movement.

[0053] To achieve a stable connection between the drive component 2 and the valve body 1, such as Figure 3As shown, the drive component 2 is connected to the main valve part 13 of the valve body 1 by fastening screws 3. The screw connection has the advantages of easy disassembly and assembly and a tight connection.

[0054] 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.
