Description

Technical Field

[0001] This application relates to the field of control valve technology, and in particular to a flavor filling flow control valve. Background Technology

[0002] With the increasing diversification of consumer demand for flavor and concentration in fragrances, fragrance manufacturers need to frequently adjust filling flow rates to adapt to different formulations in order to meet the customized requirements of different customers. As a core piece of equipment for achieving precise quantitative filling, the performance of the fragrance filling flow control valve directly affects the stability of fragrance product quality, and is also closely related to production efficiency, raw material loss rate, and the company's economic benefits.

[0003] An existing patent (publication number: CN214875752U) discloses a flow regulating valve for a filling machine. It includes a valve body, with a connecting pipe connected to the top of the valve body. A valve core is slidably connected inside the valve body, and the valve core has several adjusting holes inside. Several mounting pipes are bolted to the bottom of the valve core. A threaded sleeve is bolted to one side of the valve body, and a threaded shaft is threadedly connected to the inside of the threaded sleeve.

[0004] The above solution uses multiple regulating holes with different flow rates on the valve core. By moving the valve core, the connecting pipe is connected to different regulating holes to switch the rated flow rate. However, this adjustment mode has certain shortcomings in actual use. Due to the limited number of regulating holes, the flow rate can only be switched between a few fixed levels, and it is impossible to achieve continuous and smooth flow rate adjustment, i.e. stepless adjustment. This makes it difficult to meet the needs of some production scenarios where the filling flow rate accuracy is extremely high and the flow rate needs to be flexibly changed. Utility Model Content

[0005] The purpose of this application is to provide a flavor filling flow regulating valve that enables continuous and stepless axial movement of the valve core body, overcoming the limitation of traditional multi-hole valve cores that can only be adjusted in stages. It achieves fine and smooth control of the flow channel cross-sectional area, meets the requirements of high-precision flavor filling for flexible and continuous flow regulation, and solves the problems mentioned in the background technology.

[0006] The flavor filling flow regulating valve provided in this application adopts the following technical solution: it includes a connecting pipe, a valve body is fixedly connected to the bottom of the connecting pipe, a flow channel is opened inside the valve body, a sliding cavity is opened inside the valve body, the inner wall of the flow channel and the inner wall of the sliding cavity are connected, a valve core body is slidably connected to the inner wall of the sliding cavity, a component cavity is opened inside the valve body, a high-precision regulating component is set inside the component cavity, a lead screw is rotatably connected inside the sliding cavity, the outer side of the lead screw is threaded to the inner side of the valve core body, the high-precision regulating component includes a connecting shaft rotatably connected to the inner wall of the component cavity, one end of the connecting shaft passes through the inner wall of the component cavity and is fixedly connected to one end of the lead screw, a worm gear is fixedly connected to the outer side of the connecting shaft, a worm is meshed with the outer side of the worm gear, and both ends of the worm are rotatably connected to the inner wall of the component cavity.

[0007] By adopting the above technical solution, the rotational input can be converted into precise and minute linear displacement through the cooperation of the worm gear and worm in the high-precision adjustment component, driving the lead screw to rotate, and then driving the valve core body to move continuously and steplessly axially in the sliding cavity. This overcomes the limitation of traditional multi-hole valve cores that can only be adjusted in stages, and realizes fine and smooth control of the flow channel cross-sectional area, meeting the needs of high-precision fragrance filling for flexible and continuous flow adjustment.

[0008] Preferably, a sealing ring is fixedly embedded in the inner wall of the sliding cavity, and the outer side of the valve core body is in close contact with the inner wall of the sealing ring. The sealing ring is made of rubber.

[0010] Preferably, a guide rod is fixedly connected to the inner side of the sliding cavity, and the inner side of the valve core body is slidably connected to the outer side of the guide rod.

[0011] By adopting the above technical solution, the guide rod provides precise guidance and support for the axial movement of the valve core body, effectively preventing the valve core from deflecting or jamming during movement, ensuring the smoothness, straightness and repeatability of the valve core body movement, and guaranteeing the stability and reliability of flow regulation.

[0013] By adopting the above technical solution, the arc surface design that adapts the arc groove to the valve core body makes the valve core body fit more tightly with the inner wall of the flow channel when it moves to adjust the flow, which further enhances the sealing performance and reduces the risk of fragrance leakage at the contact point between the flow channel and the valve core body. At the same time, the arc surface setting of the valve core body can form a gradual and smooth fluid channel during the flow adjustment process, reducing fluid turbulence and pressure loss.

[0014] Preferably, a rotating wheel is rotatably connected to the inner wall of the valve body, the rotating end of the rotating wheel is fixedly connected to the rotating shaft end of the worm gear, and the outer side of the rotating wheel is covered with a rubber sleeve.

[0015] By adopting the above technical solution, the rubber-coated wheel provides a comfortable and non-slip operating interface, making it convenient for operators to manually rotate it to drive the worm gear, and then achieve fine position adjustment of the valve core body through the high-precision adjustment component.

[0017] By adopting the above technical solution, the flow scale moves with the valve core body, and the relative position change between the observation hole and the pointer fixed on the valve body provides the operator with an intuitive and visual flow indication, which facilitates the quick and accurate setting or monitoring of the current flow value and simplifies the adjustment process.

[0020] Preferably, a sealing gasket is provided inside the internally threaded sleeve, the sealing gasket is located between the connecting pipe and the discharge pipe, and the sealing gasket is made of rubber.

[0021] By adopting the above technical solution, the rubber sealing gasket is pressed between the end faces of the connecting pipe and the discharge pipe, ensuring a reliable seal at the connection and preventing fragrance leakage at the connection point.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This flavor filling flow regulating valve, by introducing a high-precision regulating component consisting of a worm gear driving a worm wheel and a connecting shaft linking a lead screw, accurately converts manual rotary input into continuous and minute linear displacement of the valve core body within the sliding cavity.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: Flavor filling flow regulating valve, refer to Figure 1 , Figure 2 and Figure 3The system includes a connecting pipe 1, with a valve body 3 fixedly connected to its bottom. The connecting pipe 1 is fixedly and sealed to external filling equipment via a flange to ensure a stable flow of flavoring into the valve body 3. The valve body 3 has a flow channel 4 and a sliding cavity 5. The inner wall of the flow channel 4 and the inner wall of the sliding cavity 5 are connected. A valve core body 6 is slidably connected to the inner wall of the sliding cavity 5. The valve body 3 also has a component cavity 7, which contains a high-precision adjustment component 8. A lead screw 9 is rotatably connected to the sliding cavity 5, and the outer side of the lead screw 9 is threaded to the inner wall of the valve core body 6. On the side, the high-precision adjustment component 8 includes a connecting shaft 801 rotatably connected to the inner wall of the component cavity 7. One end of the connecting shaft 801 passes through the inner wall of the component cavity 7 and is fixedly connected to one end of the lead screw 9. A worm gear 802 is fixedly connected to the outer side of the connecting shaft 801. A worm 803 is meshed with the outer side of the worm gear 802, and both ends of the worm 803 are rotatably connected to the inner wall of the component cavity 7. The cooperation between the worm gear 802 and the worm 803 can convert the rotary input into a precise and minute linear displacement, drive the lead screw 9 to rotate, and then drive the valve core body 6 to make continuous and stepless axial movement in the sliding cavity 5.

[0027] A sealing ring 2 is fixedly embedded in the inner wall of the sliding cavity 5. The outer side of the valve core body 6 is tightly fitted with the inner wall of the sealing ring 2. The sealing ring 2 is made of rubber. The rubber sealing ring 2 ensures a reliable seal between the valve core body 6 and the cavity wall when the valve core body 6 slides in the sliding cavity 5, effectively preventing fragrance leakage from the sliding gap, ensuring the accuracy of flow regulation and the sealing performance of the system. An arc groove 11 is opened on the inner side of the flow channel 4. The end of the valve core body 6 near the inner wall of the flow channel 4 is set with an arc surface. The arc surface of the valve core body 6 is adapted to the inner wall shape of the arc groove 11. The arc surface design of the arc groove 11 and the valve core body 6 makes the valve core body 6 fit more tightly with the inner wall of the flow channel 4 when it moves to regulate the flow, further enhancing the sealing performance and reducing the risk of fragrance leakage at the contact point between the flow channel 4 and the valve core body 6. At the same time, the arc surface setting of the valve core body 6 can form a gradual and smooth fluid channel during the flow regulation process, reducing fluid turbulence and pressure loss.

[0028] Example 2: Flavor filling flow regulating valve, refer to Figure 2 , Figure 4 and Figure 5A guide rod 10 is fixedly connected to the inner side of the sliding cavity 5. The inner side of the valve core body 6 is slidably connected to the outer side of the guide rod 10. The guide rod 10 provides precise guidance and support for the axial movement of the valve core body 6, effectively preventing the valve core from deflecting or jamming during movement, ensuring the smoothness, straightness, and repeatability of the valve core body 6's movement, and guaranteeing the stable and reliable flow regulation. A rotating wheel 12 is rotatably connected to the inner wall of the valve body 3. The rotating end of the rotating wheel 12 is fixedly connected to the rotating shaft end of the worm gear 803. The outer side of the rotating wheel 12 is covered with a rubber sleeve. The rubber-covered rotating wheel 12 provides a comfortable and non-slip operating interface, making it convenient for operators to manually rotate to drive the worm gear 803. The valve core body 6 is precisely adjusted by a high-precision adjustment component 8. A mounting groove 13 is provided on the outer side of the valve core body 6, and a flow scale 14 is fixedly connected to the inner wall of the mounting groove 13. An observation hole 15 is provided on the outer side of the valve body 3, and a pointer 16 is provided on the outside of the observation hole 15. The pointer 16 is fixedly connected to the outer side of the valve body 3. The opening of the observation hole 15 corresponds to the inner wall of the mounting groove 13. The flow scale 14 moves with the valve core body 6. The relative position change between the observation hole 15 and the pointer 16 fixed on the valve body 3 provides the operator with an intuitive and visual flow indication, which facilitates the quick and accurate setting or monitoring of the current flow value and simplifies the adjustment process.

[0029] A connecting pipe 17 is fixedly connected to the bottom of the valve body 3. A discharge pipe 18 is provided at the bottom of the connecting pipe 17. An internal threaded sleeve 19 is threaded to the outer side of the connecting pipe 17. The upper end of the discharge pipe 18 is threaded to the inner side of the internal threaded sleeve 19. The internal threaded sleeve 19 realizes a convenient and detachable connection between the connecting pipe 17 and the discharge pipe 18, which facilitates quick replacement or cleaning of the downstream pipeline according to different filling needs. A sealing gasket 20 is provided inside the internal threaded sleeve 19. The sealing gasket 20 is located between the connecting pipe 17 and the discharge pipe 18. The sealing gasket 20 is made of rubber. The rubber sealing gasket 20 is pressed between the end faces of the connecting pipe 17 and the discharge pipe 18 to ensure a reliable seal at the connection and prevent fragrance leakage at the connection.

[0030] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the fragrance filling flow rate, the operator rotates the rotating wheel 12. The rotation of the rotating wheel 12 drives the worm 803 fixed thereto to rotate. The worm 803 drives the worm wheel 802 meshing with it to rotate. At this time, the worm wheel 802 transmits the rotational motion to the lead screw 9 through the connecting shaft 801. Since the lead screw 9 and the valve core body 6 are connected by threads, and the valve core body 6 can only move axially under the constraint of the guide rod 10, the rotation of the lead screw 9 is accurately converted into the linear displacement of the valve core body 6 in the sliding cavity 5. At this time, the position of the valve core body 6 in the flow channel 4 changes, thereby continuously and smoothly changing the effective flow cross-sectional area of ​​the flow channel 4. At the same time, the arc surface at the end of the valve core body 6 can form a gradual and smooth fluid channel during the flow adjustment process, reducing fluid turbulence and pressure loss. Meanwhile, the arc groove 11 and the valve core body 6 make the valve core body 6 fit more tightly with the inner wall of the flow channel 4 when moving to adjust the flow rate, further enhancing the sealing performance. When the valve core body 6 is away from the arc groove 11, the flow area increases and the flow rate increases; when it is closer, the flow area decreases and the flow rate decreases. At this time, the sealing ring 2 can ensure the seal at the sliding point. During the adjustment process, the operator can visually read the current flow rate setting value by observing the position of the flow rate scale 14 on the valve core body 6 relative to the pointer 16 through the observation hole 15. The fragrance finally flows out through the channel 4, the connecting pipe 17, the internal threaded sleeve 19, and the sealing gasket 20, which is sealed to the discharge pipe 18 for filling. This design realizes the core function of stepless, precise, and continuous flow rate adjustment.
