Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, and in particular to a connection knob and an electric valve. Background Technology

[0002] In the HVAC industry, valves are needed to control the flow of liquids in pipelines. To further improve the convenience of control, electric valves are commonly used to control the on / off state of the pipeline. An electric valve mainly consists of an electric actuator and a valve body. The actuator's connector is connected to the valve stem of the valve body via a nut. The electric actuator drives the valve stem to rotate, which in turn drives the valve core to rotate, thus controlling the on / off state of the pipeline. However, during installation, operators typically connect the valve body by hand-tightening the nut. Because the nut is small and the electric actuator is large, it is inconvenient to apply external force when tightening, making it difficult to quickly and accurately position and install the valve body and actuator.

[0003] Therefore, there is an urgent need for a connecting knob and electric valve to solve the above-mentioned technical problems. Utility Model Content

[0007] Connecting components, used to connect the valve body and the actuator;

[0008] A screwing component is coaxially sleeved outside the connector, and the screwing component is circumferentially fixed to the connector. When the screwing component is rotated, it can drive the connector to rotate synchronously around the axis. The outer periphery of the screwing component is provided with protrusions.

[0009] Preferably, multiple protrusions are provided, and each protrusion is distributed at intervals along the circumference of the screwing member, forming a limiting space between two adjacent protrusions.

[0012] Preferably, the protrusion is provided with at least one anti-slip part.

[0013] Preferably, the outer periphery of the connector is provided with serrations, which abut against the inner wall of the screwing component.

[0014] Preferably, the connector is made of metal and the screwing part is made of plastic.

[0015] Preferably, one end of the connector is provided with a limiting protrusion, and the outer periphery of the joint is provided with a limiting portion. The limiting protrusion can abut against the limiting portion to prevent the connector from falling off the joint.

[0016] The other end of the connector is threaded into the valve body.

[0017] Another objective of this invention is to provide an electric valve that ensures ease of use and enhances the user experience.

[0018] To achieve this objective, the present invention adopts the following technical solution:

[0023] Preferably, the connector is eccentrically positioned on the execution body.

[0024] The beneficial effects of this utility model are:

[0025] This utility model discloses a connection knob and an electric valve. The connection knob specifically includes a connector and a screwing component. The connector is used to connect the valve body and the actuator, and its outer circumference is serrated. The screwing component is coaxially sleeved around the connector, and the screwing component and the connector are circumferentially fixed. Rotating the screwing component can drive the connector to rotate synchronously around its axis. The outer circumference of the screwing component is provided with protrusions. This structure can increase the rotational torque when connecting the valve body and the actuator, thereby effectively reducing assembly difficulty and improving assembly efficiency and accuracy.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In the description of this embodiment, the terms "upper," "lower," "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.

[0043] This embodiment provides an electric valve, specifically as follows: Figure 1 and Figure 2As shown, the electric valve includes a valve body 100, an actuator 200, and a connection knob. The valve body 100 includes a valve stem 110, a pipeline 120, and a valve core 130. The valve core 130 is disposed within the pipeline 120. One end of the valve stem 110 is connected to the valve core 130, and the other end extends out of the pipeline 120. The actuator 200 includes a connector 210 and an actuator body 220. The valve stem 110 can be connected to the connector 210. One end of the connection knob can be connected to the valve body 100, and the other end is connected to the outer periphery of the connector 210. In this electric valve, the actuator body 220 can automatically control the rotation of the valve stem 110, which can indirectly drive the rotation of the valve core 130, thereby controlling the opening and closing of the pipeline 120 according to actual needs. When maintenance or replacement of parts is required, the operator manually turns the connection knob to disassemble the valve body 100 from the actuator 200. However, the actuator 200 in the existing technology is relatively large, so it is inconvenient to apply external force (small rotational torque) when turning the connection knob between the actuator 200 and the valve body 100, thus making it impossible to quickly complete the disassembly and assembly. At the same time, due to the inconvenience of operation, the positioning accuracy will also be affected, thus affecting the performance.

[0044] To address the aforementioned technical problems, this embodiment also provides a connection knob for connecting the valve body 100 and the actuator 200. Specifically, as follows... Figure 2 and Figure 3 As shown, the connection knob includes a connector 10 and a screwing component 20. The connector 10 is used to connect the valve body 100 and the actuator 200 to a joint 210. The outer periphery of the connector 10 is provided with serrations 11. The screwing component 20 is coaxially sleeved on the outside of the connector 10, and the screwing component 20 and the connector 10 are circumferentially fixed. Rotating the screwing component 20 can drive the connector 10 to rotate synchronously around the axis. The outer periphery of the screwing component 20 is provided with protrusions 21.

[0045] In this structure, one end of the connecting part 10 of the connecting knob is connected to the valve body 100, and the other end is connected to the connector 210, which ensures that the actuator 200 will not detach from the valve body 100 when the electric valve is in use. The screwing part 20 is circumferentially fixed to the connecting part 10, so the screwing part 20 can rotate together with the connecting part 10, thereby locking the valve body 100 and the connector 210. In addition, the protrusion 21 on the outer periphery of the screwing part 20 also increases the screwing torque, thereby effectively reducing the assembly difficulty and improving the assembly accuracy.

[0046] It should be noted that, as Figure 4As shown, one end of the connector 10 is provided with a limiting protrusion 12, and the outer periphery of the connector 210 is provided with a limiting portion 230. The limiting protrusion 12 can abut against the limiting portion 230 to prevent the connector 10 from falling off the connector 210; the other end of the connector 10 is threadedly engaged with the valve body 100. Tighten the connection knob until the bottom end of the limiting protrusion 12 abuts against the top end of the limiting portion 230. At this time, the valve body 100 and the connector 10 are threadedly fixed, and the limiting protrusion 12 restricts the actuator 200 from falling off the axial direction of the connector 10, thereby indirectly connecting the valve body 100 and the actuator 200 into a whole, and the valve body 100 and the actuator 200 will not fall off along the axial direction of the connector 10, ensuring good connection stability.

[0047] Furthermore, the connector 10 is made of metal, while the screw-on part 20 is made of plastic. The valve stem 110 extends into the connector 210, and the connector 10 directly mates with the valve body 100 and the connector 210 to ensure a stable connection between the valve body 100 and the actuator 200. Under these conditions, using metal increases the connection strength, ensuring that the connection will not bend or break, thus ensuring that the valve core 130 can open normally. Since the operator needs to directly contact the screw-on part 20, using plastic improves the operator's comfort during assembly and also reduces the overall weight of the connecting knob, improving the user experience.

[0048] Furthermore, the color of the screw-on component 20 is different from that of the valve body 100 and the actuator 200. Using a different color for the screw-on component 20 improves its visibility, allowing operators to quickly locate it when maintenance or replacement is needed, thereby improving operational efficiency.

[0049] It should be noted that in this embodiment, the connector 10 is made of copper, which has higher strength and better corrosion resistance; the screw-on part 20 is made of plastic, which is not only lower in cost but also easier to process and demold; and the screw-on part 20 is made of blue plastic. In other embodiments, other colors can be sprayed on the surface according to actual needs.

[0050] Furthermore, the connector 10 and the screwing part 20 are interference-fitted. This fit ensures that the screwing part 20 and the connector 10 rotate synchronously without slippage, thus effectively improving the user experience and indirectly increasing assembly efficiency.

[0051] In addition, such as Figure 3 and Figure 4 As shown, the outer periphery of the connector 10 is provided with serrations 11, which abut against the inner wall of the screwing component 20. The serrations 11 can further increase the friction between the outer periphery of the connector 10 and the inner wall of the screwing component 20, thereby ensuring that the screwing component 20 will not rotate relative to the connector 10 during the screwing process, thus ensuring assembly efficiency.

[0052] It is worth noting that in this embodiment, after demolding, the screw-on part 20 is relatively soft due to its high temperature. If the connector 10 is placed directly into the central hole of the screw-on part 20, the screw-on part 20 will shrink as the temperature decreases. Figure 4 As shown, at this time, the inner wall of the screwing part 20 can tightly wrap around the outer periphery of the serration 11 of the connector 10, thereby further ensuring that the screwing part 20 will not spin freely with the connector 10, thereby improving the connection efficiency and user experience.

[0053] like Figure 3 As shown, multiple protrusions 21 are provided, and each protrusion 21 is distributed circumferentially along the screwing component 20, forming a limiting space 23 between adjacent protrusions 21. The circumferentially distributed protrusions 21 ensure that the operator has a corresponding point of force regardless of the angle to which the screwing component 20 is rotated, thereby further reducing the difficulty of operation and improving the overall aesthetics. In addition, during disassembly or installation, the operator does not need to hold the protrusions 21, but only needs to wedge their fingers into the limiting space 23. At this time, applying force in a clockwise or counterclockwise direction can drive the screwing component 20 to rotate in the same direction, thereby enabling quick disassembly or assembly, further improving the convenience when using this structure to connect the valve body 100 and the actuator 200.

[0054] It should be noted that in this embodiment, a total of six protrusions 21 are provided, and the six protrusions 21 are evenly distributed along the circumference of the screwing member 20. Each limiting space 23 can accommodate at least one finger of an adult. In other embodiments, the number of protrusions 21 can be adjusted according to actual needs, as long as it is ensured that at least one finger of an adult can be inserted into the limiting space 23 and rotate the screwing member 20.

[0055] To further explain, such as Figure 6 As shown, at least one protrusion 21 can extend out of the edge of the actuator 200. This arrangement makes it easier for the operator to insert their fingers into the limiting space 23 when disassembling the electric valve, thereby improving ease of use and disassembly / reassembly speed.

[0056] In addition, such as Figure 6 As shown, the connector 210 is eccentrically positioned on the actuator 220. This structure shortens the distance between the connector 210 and one edge of the actuator 220, allowing the protrusion 21 to extend out of the actuator 220 without requiring additional length during processing. This reduces processing difficulty and cost, while also ensuring the lightweight design of the connecting knob and improving the user experience.

[0057] Specifically, such as Figure 3As shown, the line connecting the end of each protrusion 21 furthest from the screwing component 20 to the center of the screwing component 20 forms an angle α with the tangent along the edge of the screwing component 20 at the location of the corresponding protrusion 21, and the angle α is an obtuse angle. This structure can effectively reduce the radial protrusion size of the protrusion 21, ensuring the aesthetics of the structure while reducing space occupation; in addition, the inclined protrusion 21 can also provide convenience for the fingers to be engaged in the limiting space 23, thereby ensuring the assembly experience of the operator.

[0058] To further improve rotational efficiency, such as Figure 3 As shown, each protrusion 21 is provided with at least one anti-slip portion 22. The anti-slip portion 22 can increase the friction between the finger and the protrusion 21, thereby preventing slippage during twisting. In this embodiment, each protrusion 21 is provided with multiple anti-slip portions 22. Multiple anti-slip portions 22 can increase the points where the finger can exert force, thereby ensuring a sufficient anti-slip effect and preventing the finger from slipping out of the limiting space 23 during rotation, thus ensuring a good rotation effect.

[0059] In addition, such as Figure 3 As shown, multiple anti-slip parts 22 are distributed circumferentially along the protrusion 21. This arrangement ensures that the screw 20 can be rotated to any angle, and that the finger can contact the anti-slip part 22 within each limiting space 23, thereby indirectly improving practicality and ease of operation.

[0060] Considering the security of use, such as Figure 3 As shown, the outer periphery of the anti-slip part 22 is arc-shaped. This design avoids sharp structures in the anti-slip part 22, effectively preventing operators' palms from being scratched, while also ensuring the comfort of operators when rotating the screw-on part 20, thereby improving the user experience.

[0061] In summary, using the connection knob in this embodiment to connect the valve body 100 and the actuator 200 not only reduces the difficulty of operation but also increases assembly efficiency and accuracy.
