Description

Technical Field

[0001] The present application relates to the field of valve cores, and in particular to a valve stem assembly, a valve core, and a water distributor. Background Art

[0002] In water conservancy and HVAC systems, manifold valves are key components for controlling fluid distribution, and their design and manufacturing efficiency are directly related to the performance and cost of the system. In the design of traditional manifold valves, the valve stem of the valve core often adopts an integrated structure. Although this design ensures a high degree of integration and stability between the valve stem and the valve core, it faces significant challenges in the actual processing process. Due to the complex shape of the valve stem, especially its length and diameter variations and possible features such as threads and sealing surfaces, turning becomes a necessary step. However, in order to meet these precise geometric requirements, a large amount of material has to be removed during the processing, which not only prolongs the production cycle and increases the difficulty of processing, but also leads to a large amount of waste of raw materials, thereby increasing manufacturing costs.

DETAILED DESCRIPTION

[0030] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0033] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0034] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0035] Existing valve stems are usually one-piece, and due to the requirements of the valve stem structure, the valve stem diameter may not be different in the length direction, which leads to the fact that during processing, in order to meet the structural requirements, the excess part is cut off, but it requires a material with a larger diameter to complete the processing of the entire valve stem. However, if the valve stem is divided into two or more parts, different diameter materials are selected according to the different diameters of the valve stem parts, and then the various parts are connected and installed to form a complete valve stem, the waste of material can be reduced as much as possible, thereby improving the processing efficiency and difficulty as well as the waste of material.

[0036] In this application, the valve stem is divided into an active component 100 and a passive component 200 , and then after the active component 100 and the passive component 200 are processed, the active component 100 and the passive component 200 are connected through a connecting structure 300 to be fully assembled.

[0037] See also Figure 1 As shown, an embodiment of the present application discloses a valve stem assembly. Specifically, the valve stem assembly includes an active member 100, a driven member 200 and a connecting structure 300. The active member 100 is connected to the driven member 200. The connecting structure 300 is located at the connection between the active member 100 and the driven member 200. The connecting structure 300 is used for the detachable installation connection between the active member 100 and the driven member 200. A accommodating groove 400 is provided on the outer peripheral surface of the connecting structure 300.

[0038] Please continue reading Figure 1As shown, in order to meet the processing needs of the active member 100 and the driven member 200, when selecting materials, a material slightly larger than the diameter of the active member 100 should be selected for processing the active member 100. Correspondingly, a material slightly larger than the maximum diameter of the driven member 200 should also be selected for processing the driven member 200. Therefore, when performing cutting processing, only the parts larger than the diameters of the active member 100 and the driven member 200 need to be cut off, and then other structures can be processed. Finally, the active member 100 and the driven member 200 are assembled to form a complete valve stem, thereby greatly reducing the waste of materials.

[0039] In some embodiments, the active member 100 and the driven member 200 are both rotating bodies. More specifically, the active member 100 and the driven member 200 are rod-shaped metals, and can be processed by turning.

[0040] In this embodiment, a connection structure 300 is provided at the connection between the active member 100 and the driven member 200 . After the main bodies of the active member 100 and the driven member 200 are processed, the active member 100 and the driven member 200 are connected via the connection structure 300 .

[0041] Furthermore, the active part 100 and the driven part 200 adopt a split connection method, which is convenient for subsequent repair and maintenance. For example, when the active part 100 and the driven part 200 are damaged, it is only necessary to replace the active part 100 and the driven part 200 separately, thereby reducing the cost of subsequent maintenance. If the active part 100 and the driven part 200 are arranged in an integrated manner, it is necessary to replace the active part 100 and the driven part 200 at the same time, thereby increasing the cost of subsequent maintenance. Moreover, for a smaller space such as the valve core, it is inconvenient to replace the entire part, which increases the difficulty of replacement. It can be seen that the split connection between the active part 100 and the driven part 200 can not only reduce production and processing costs and improve production efficiency, but also reduce subsequent repair and maintenance costs.

[0042] The connecting structure 300 includes a threaded hole 310 opened on the end face of the driven member 200 facing the active member 100, and a first external thread 320 is provided on the outer surface of the end of the active member 100 facing the driven member 200. The active member 100 is connected to the driven member 200 by threading the threaded hole 310 and the first external thread 320.

[0043] See Figure 2 and Figure 3As shown, in this embodiment, the driven member 200 and the active member 100 are connected by threads. Specifically, a threaded hole 310 is opened on the end face of the driven member 200, and an external thread is opened on the outer surface of the end of the active member 100. The connection between the active member 100 and the driven member 200 is achieved by connecting the external thread and the internal thread.

[0044] In one embodiment, the external thread opened at the end of the active member 100 toward the driven member 200 and the internal thread in the threaded hole 310 can be fine-pitch threads. Fine-pitch threads have good self-locking properties and are not prone to loosening, thereby preventing the active member 100 and the driven member 200 from separating to the greatest extent. Furthermore, other types of threads can also be used for the threads, which are not specifically limited here.

[0045] For example, in one embodiment, a small cylinder can be provided at the end of the driven member 200 facing the driving member 100, and then an external thread can be opened on the small cylinder. Then, a blind hole with an internal thread can be opened on the end face of the driving member 100 facing the driven member 200, and then the external thread on the cylinder and the internal thread in the blind hole can be threadedly connected, thereby realizing the connection and installation between the driving member 100 and the driven member 200.

[0046] In one embodiment, the threaded hole 310 may be a through hole or a blind hole. In this embodiment, the threaded hole 310 has an internal thread.

[0047] The follower 200 includes a follower block 210, and a first stopper 220 is provided at the end of the outer peripheral surface of the follower block 210 facing the active member 100, and a second stopper 230 is provided at the end of the outer peripheral surface of the follower block 210 away from the first stopper 220. The first stopper 220 and the second stopper 230 define the accommodating groove 400.

[0048] See Figure 2 and Figure 3 As shown, in actual processing, the receiving groove 400 is generally cut first, and the first stop block 220 and the second stop block 230 are located on both sides of the receiving groove 400, thereby limiting the object loaded into the receiving groove 400 and preventing the object from separating from the receiving groove 400, that is, the first stop block 220 and the second stop block 230 play a role of blocking and limiting.

[0049] In one embodiment, the accommodating groove 400 is an annular groove, that is, an annular groove. The depth and width of the annular groove can be designed according to the actual size, and the specific parameters are not limited.

[0050] The end surface of the first stopper 220 facing the active member 100 is an inclined surface, and the inclination angle of the inclined surface is α, which satisfies: 30°≤α≤60°.

[0051] See Figure 2 、 Figure 5 、 Figure 6 as well as Figure 7 As shown, a spring needs to be provided at the position of the first stopper 220. In order to enable the spring to always abut against the end face of the first stopper 220, the end face of the first stopper 220 can be set as an inclined surface so that the spring always abuts against the inclined surface.

[0052] In one embodiment, the inclination angle α of the inclined surface can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. In this embodiment, the inclination angle is 45°. In practice, the design can be selected according to needs and is not limited here.

[0053] A screwing member 500 is provided on the end surface of the driven member 200 away from the driving member 100 .

[0054] See Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, when the active member 100 and the driven member 200 are assembled, the active member 100 and the driven member 200 need to be screwed in opposite directions to achieve a connection between the threads. In order to facilitate the connection and installation, a screwing member 500 is provided at the end of the driven member 200. The driven member 200 can be driven to rotate by the cooperation of the wrench and the screwing member 500, so that the active member 100 and the driven member 200 can be screwed and connected.

[0055] Exemplarily, the screwing member 500 is a regular polygonal protrusion or a regular polygonal groove.

[0056] In one embodiment, when the screwing member 500 is a regular polygonal protrusion, it can be a regular triangle, a regular quadrilateral, a regular pentagon, a regular hexagon, etc. In this embodiment, the screwing member 500 can be a regular hexagonal protrusion, so that it can be adapted for use with a regular hexagonal sleeve, etc.

[0057] In one embodiment, when the screwing member 500 is a regular polygonal groove, the groove is a blind groove, that is, it does not pass through the driven member 200. The groove can be a regular triangle, a regular quadrilateral, a regular pentagon, a regular hexagon, etc. In this embodiment, the screwing member 500 can be a regular hexagonal groove, which can be used with a regular hexagonal wrench.

[0058] In one embodiment, the screwing member 500 can also be a straight-line protrusion or groove. When the screwing member 500 is a straight-line protrusion, the follower 200 can be directly screwed by hand through the straight-line protrusion as the force point, so that the follower 200 is connected to the active member 100. Furthermore, when the screwing member 500 is a straight-line groove, it can be used with a straight-line screwdriver for screwing. Furthermore, the screwing member 500 can also be a cross-shaped groove, which can be used with a cross-shaped screwdriver for screwing.

[0059] In one embodiment, the screwing member 500 can be at least two evenly distributed circular holes (not shown in the figure) opened on the end face of the second stop block 230 away from the first stop block 220. It should be noted that the circular holes are blind holes, that is, the circular holes are not connected to the accommodating groove 400. When screwing is required, the circular holes on the end face of the second stop block 230 can be used as force points to screw the follower 200 as a whole.

[0060] In this embodiment, the first stopper 220 and the second stopper 230 are both circular.

[0061] A second external thread 600 is provided on the outer surface of the end of the driving member 100 away from the driven member 200 .

[0062] See Figure 1 As shown, in order to facilitate the connection between the active part 100 and other parts, a second external thread 600 is provided on the outer surface of the end of the active part 100 away from the first external thread 320, and threaded connection is performed with other parts through the second external thread 600. In addition to using threaded connection to connect with other parts, other methods can also be used, which are not limited here.

[0063] For example, a blind hole may be provided on the end surface of the driving member 100 away from the driven member 200 , and an internal thread may be provided in the blind hole, so that the driving member 100 is connected to other components through the internal thread.

[0064] See also Figure 4 、 Figure 5 、 Figure 6 as well as Figure 7 As shown, a sealing member 700 is provided in the accommodating groove 400, and the water outlet or water inlet of the valve core can be sealed by the sealing member 700. The sealing member 700 can be specifically a sealing ring, such as an O-ring, a rectangular sealing ring, etc., which can be selected according to actual needs.

[0065] It should be noted that the sealing member 700 should partially protrude from the first stopper 220 and the second stopper 230 .

[0066] An embodiment of the present application further provides a valve core, which includes the valve stem assembly described in any one of the above items.

[0067] See also Figure 6 and Figure 7 As shown, the valve stem assembly described above is installed inside the valve core, and is mainly used for switching water channels, sealing and other functions. In practice, the valve stem assembly described above can play the role of switching and other functions according to the valve core with different functions.
