Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, and in particular to an anti-drip structure for filling valves. Background Technology

[0002] In the liquid filling process of beverage production, the filling valve, as the core component controlling the quantitative output of liquid, directly affects the filling accuracy, the cleanliness of the production environment, and subsequent processing costs due to its operational stability and sealing performance. Currently, mainstream filling valves on the market typically consist of a valve body, valve tube, and basic control components. Liquid delivery and shut-off are achieved through the opening and closing of the valve core inside the valve body, meeting the needs of continuous filling operations.

[0003] In practical production applications, existing filling valves generally suffer from the technical problem of residual liquid dripping after the valve body is closed: after the filling operation is completed and the valve body and valve core close to cut off the main liquid flow, some liquid remains inside the valve tube and at the outlet. This residual liquid slowly drips onto the filling table or the conveying mechanism below due to gravity. The dripping liquid easily accumulates on the table, and beverages may also adhere to the gaps in the table or the surface of the conveying components, requiring regular manual wiping and cleaning. This increases the manual cleaning costs during the production process and may also lead to bacterial growth if cleaning is not timely, posing a potential threat to food hygiene and safety.

[0004] Therefore, this application provides a drip-proof structure for filling valves to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a drip-proof structure for filling valves, which can prevent residual liquid from dripping onto the table surface and splashing to the surrounding area after the valve body is closed, thus increasing the subsequent cleaning costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] The anti-drip structure of the filling valve includes the valve body;

[0008] The valve tube is connected to the outlet of the valve body via a thread;

[0009] A leak-proof assembly is disposed on one side of a valve pipe. The leak-proof assembly includes a mounting frame, a drive motor is mounted on the bottom of the mounting frame, a rotating rod is fixedly connected to the output end of the drive motor, a rotating plate is fixedly connected to the bottom end of the rotating rod, a sealing block is fixedly connected to the top of the rotating plate, and a sealing ring plate is fixedly connected to the top of the rotating plate outside the sealing block.

[0010] A connecting component is disposed between the leak-proof component and the valve pipe for connecting the leak-proof component and the valve pipe;

[0011] An anti-drip assembly is disposed at the bottom of the valve tube.

[0012] The leak-proof component uses a drive motor to insert a sealing block into the outlet end of the valve tube and a sealing ring plate to fit against the end face of the valve tube, forming a leak-proof structure that can directly block the outflow of residual liquid from the outlet end of the valve tube. Furthermore, the anti-drip component is located inside the valve tube, thus creating an internal sealing effect.

[0013] Optionally, the leak-proof assembly further includes a mounting plate, on the bottom of which a hydraulic telescopic rod is mounted, and the output end of the hydraulic telescopic rod is fixedly connected to the mounting frame.

[0014] The hydraulic telescopic rod can drive the mounting frame to move up and down precisely in the vertical direction, thereby adjusting the relative position of the sealing block and the outlet end of the valve tube. After filling, the hydraulic telescopic rod drives the sealing block to be precisely inserted into the outlet of the valve tube, avoiding the sealing block from shifting or the sealing ring plate from not fitting tightly due to human or mechanical errors. Before filling begins, the telescopic rod drives the sealing block to quickly detach from the valve tube without affecting the liquid delivery.

[0015] Optionally, the bottom of the mounting frame is provided with an annular groove, and a sliding rod is slidably connected to the inner wall of the annular groove. The bottom end of the sliding rod is fixedly connected to the rotating plate.

[0016] The sliding rod slides along the annular groove, providing circumferential guidance and radial limit for the rotating plate. When the drive motor drives the rotating plate to rotate, the sliding rod can limit the radial displacement of the rotating plate, preventing the sealing block from deviating from the central axis of the valve tube during rotation. At the same time, it reduces the swaying amplitude of the rotating plate, ensuring the coaxiality of the sealing block when inserted into the valve tube and the flatness of the sealing ring plate when it fits.

[0017] Optionally, the connecting assembly includes an annular retaining frame, the inner surface of which is fixedly connected to the outer surface of the valve pipe, and an annular retaining block is engaged with the inner wall of the annular retaining frame.

[0018] The annular frame is fixed to the valve pipe, and the annular block is linked to the leak-proof component. The two are connected by an annular slot. When installing the leak-proof component, only the annular block needs to be inserted into the annular frame to complete the initial fixation. There is no need for bolts to pass through the valve pipe or welding. When disassembling, the block and frame are directly separated without disassembling the valve pipe or other components.

[0019] Optionally, a connecting plate is fixedly connected to one side of the annular card block, and one side of the connecting plate is fixedly connected to one side of the mounting plate. An auxiliary slot is provided on one side of the annular card frame.

[0020] The auxiliary slot is connected to the annular slot, allowing for quick alignment of the annular block and the annular frame during installation.

[0021] Optionally, the top of the annular card frame is provided with a circular insertion hole, and the top of the annular card block is fixedly connected with a threaded insertion rod, which is inserted into the inner wall of the circular insertion hole and fixedly connected with a fixing nut.

[0022] After the threaded insert passes through the round insertion hole, it is locked with a fixing nut to form a fixed position. The threaded locking ensures that the annular locking block will not fall off the annular locking frame due to equipment vibration or liquid impact during long-term use, thus avoiding leakage caused by displacement of the leak-proof component.

[0023] Optionally, the anti-drip assembly includes two mounting slots, which are symmetrically opened on the inner wall of the valve pipe. An auxiliary rotating rod is rotatably arranged on the inner wall of the mounting slot. A rotating plate is fixedly connected to one end of the auxiliary rotating rod, and a rubber ring plate is fixedly connected to the side of the rotating plate.

[0024] The rubber ring plate fits against the contact surface between the rotating plate and the inner wall of the valve pipe to prevent liquid from leaking out of the gap.

[0025] Optionally, a torsion spring is fitted on the outer surface of the auxiliary rotating rod, and the two ends of the torsion spring are fixedly connected to the outer surface of the rotating plate and the inner wall of the mounting groove, respectively.

[0026] The torsion spring provides continuous restoring force to the rotating plate. When there is no liquid delivery, the torsion spring drives the rotating plate to close automatically without manual or motor control. When there is liquid delivery, the liquid pressure can easily overcome the torsion spring force to push the rotating plate open without affecting the liquid flow rate.

[0027] Compared with the prior art, this utility model has at least the following beneficial effects:

[0028] The leak-proof component can be used to seal the bottom outlet of the valve tube when it is not in use, thus effectively preventing residual liquid from dripping out. When in use, the sealing block and other structures can be rotated to one side, so as not to affect filling and dispensing. The leak-proof component can also be connected to the valve tube with the help of the connecting component, which facilitates disassembly and maintenance.

[0029] With the help of the anti-drip component, the valve tube can be prevented from leaking inside. When liquid flows out, the impact force of the liquid drives the rotating plate to rotate, thus allowing liquid to flow out. When no liquid is flowing out, the rotating plate is reset by the action of the torsion spring, thus sealing the inner wall of the valve tube. Attached Figure Description

[0048] The anti-drip structure for the filling valve provided in this embodiment aims to solve the problem of residual liquid dripping onto the countertop and splashing to the surrounding area after the valve body is closed, increasing subsequent cleaning costs. The following technical solution is provided to address the issues of residual liquid dripping and increased subsequent cleaning costs. The anti-drip structure is composed of a valve body 1, a valve tube 2, an anti-drip component 3, a connecting component 4, and an anti-drip component 5. These components work together to seal the residual liquid inside the valve tube 2, preventing dripping.

[0049] like Figures 1-6 As shown, embodiments of this utility model provide an anti-drip structure for filling valves, such as... Figure 1 As shown, the valve body consists of a valve body 1, a valve tube 2, a leak-proof component 3, a connecting component 4, and a drip-proof component 5. The valve body 1 is a DN40 straight-through filling valve made of 304 stainless steel. It has a 25mm inner diameter outlet at its bottom, with an M30×1.5 internal thread machined on the inner wall for connection to the valve tube 2. One end of the valve tube 2 is detachably connected to the outlet of the valve body 1 via a thread. The valve tube 2 is made of food-grade 316L stainless steel, with a total length of 150mm, an inner diameter of 25mm (matching the inner diameter of the outlet of the valve body 1), and an outer diameter of 32mm. The upper end of the valve tube 2, near the valve body 1, has an M30×1.5 external thread on its outer wall, which matches the internal thread of the outlet of the valve body 1. The detachable connection is achieved through thread engagement. The valve tube 2 is a hollow tubular structure for conveying liquid. The leak-proof component 3 is located on one side of the outlet end of the valve tube 2 and is used to actively seal and prevent leakage at the outlet end of the valve tube 2. Figure 1 , Figure 3 and Figure 4 As shown, the leak-proof component 3 includes a mounting frame 33. A drive motor 34 is fixedly mounted at the bottom of the mounting frame 33. A first rotating rod 35 is fixedly connected vertically to the output end of the drive motor 34. A rotating plate 36 is horizontally fixedly connected to the bottom end of the first rotating rod 35. A sealing block 310 is fixedly connected to the center of the top of the rotating plate 36. The outer diameter of the sealing block 310 is adapted to the inner diameter of the valve pipe 2 and is used to insert into the outlet of the valve pipe 2 to achieve sealing. A sealing ring plate 39 is coaxially fixedly connected to the top of the rotating plate 36 outside the sealing block 310. The inner diameter of the sealing ring plate 39 is adapted to the outer diameter of the sealing block 310, and the outer diameter is larger than the outer diameter of the valve pipe 2. It is used to fit the end face of the outlet of the valve pipe 2 to enhance the sealing effect. Figure 1 As shown, the connecting component 4 is disposed between the leak-proof component 3 and the valve pipe 2, and is used to detachably connect the leak-proof component 3 to the outer wall of the valve pipe 2, as shown. Figure 1 As shown, the anti-drip component 5 is installed on the bottom inner wall of the valve pipe 2, which is used to passively seal the outlet of the valve pipe 2 to prevent dripping, and automatically closes and seals when there is no liquid pressure.

[0050] Through the function of the leak-proof component 3 and the connecting component 4, the leak-proof component 3 can be installed with the valve pipe 2, thereby actively sealing and preventing leakage at the outlet of the valve pipe 2, and preventing liquid from dripping inside the valve pipe 2 after the valve body 1 is closed.

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, the leak-proof component 3 also includes a mounting plate 31. A hydraulic telescopic rod 32 is fixedly installed at the bottom of the mounting plate 31 in the vertical direction. The output end of the hydraulic telescopic rod 32 is fixedly connected to the top of the mounting frame 33, which is used to drive the mounting frame 33 to rise and fall in the vertical direction to adjust the relative position of the sealing block 310 and the liquid outlet of the valve pipe 2, so as to realize that the sealing block 310 is inserted into or removed from the liquid outlet of the valve pipe 2.

[0052] like Figure 3 As shown, the bottom of the mounting frame 33 is provided with an annular groove 38 coaxial with the first rotating rod 35. Four sliding rods 37 are slidably connected to the inner wall of the annular groove 38. The sliding rods 37 are evenly distributed along the circumference of the annular groove 38. The bottom end of the sliding rod 37 is fixedly connected to the top of the rotating plate 36, which is used to guide and limit the rotation of the rotating plate 36 and improve the stability of the rotating plate 36 when it rotates.

[0053] like Figures 3-5 As shown, the connecting component 4 includes an annular frame 41. The inner surface of the annular frame 41 is coaxially and fixedly connected to the outer surface of the valve pipe 2. An annular groove is provided on the inner wall of the annular frame 41, and an annular block 42 is adapted to be engaged in the annular groove.

[0054] like Figures 3-5 As shown, a connecting plate 44 is fixedly connected to one side of the annular card block 42 in the horizontal direction. The side of the connecting plate 44 away from the annular card block 42 is fixedly connected to one side of the mounting plate 31. An auxiliary slot 43 is provided on one side of the annular card frame 41. The auxiliary slot 43 communicates with the annular card groove and is used to assist the positioning and engagement of the annular card block 42 and the annular card frame 41, so that the annular card block 42 can be quickly inserted into the annular card groove.

[0055] like Figures 3-5 As shown, the top of the annular frame 41 has a circular insertion hole 45 that extends through to the annular slot. The top of the annular block 42 is fixedly connected with a threaded rod 46 corresponding to the position of the circular insertion hole 45. The top end of the threaded rod 46 passes through the circular insertion hole 45 and extends to the top of the annular frame 41. The portion of the threaded rod 46 located above the annular frame 41 is threadedly connected with a fixing nut 47. The bottom surface of the fixing nut 47 is in contact with the top surface of the annular frame 41 to lock the annular block 42 onto the annular frame 41.

[0056] like Figure 1 and Figure 6As shown, the anti-drip assembly 5 includes two mounting grooves 51, which are symmetrically opened on the bottom inner wall of the valve pipe 2 and symmetrically distributed along the diameter direction of the valve pipe 2. An auxiliary rotating rod 52 is rotatably connected to the inner wall of the mounting groove 51 in the horizontal direction. A rotating plate 53 is fixedly connected to one end of the auxiliary rotating rod 52. A rubber ring plate 54 is fixedly connected to the side of the rotating plate 53. The rubber ring plate 54 is used to seal the gap between the rotating plate 53 and the inner wall of the valve pipe 2.

[0057] like Figure 6 As shown, a torsion spring 55 is sleeved on the outer surface of the auxiliary rotating rod 52. One end of the torsion spring 55 is fixedly connected to the outer surface of the rotating plate 53, and the other end is fixedly connected to the inner wall of the mounting groove 51. The torsion spring 55 is used to provide a reset force for the rotating plate 53. Under normal conditions, the two rotating plates 53 remain closed. When there is liquid pressure in the valve pipe 2, the liquid pushes the rotating plate 53 to overcome the spring force of the torsion spring 55 and open. After the liquid is discharged, the torsion spring 55 drives the rotating plate 53 to reset and close.

[0058] Working principle

[0059] like Figures 1-6 As shown, in use, the annular locking block 42 is engaged with the annular locking frame 41. At this time, the threaded rod 46 can be inserted into the inner wall of the auxiliary slot 43. Then, the fixing nut 47 is fixed to the threaded rod 46.

[0060] Activating the hydraulic telescopic rod 32 can drive the mounting frame 33 to move, which in turn indirectly drives the rotating plate 36 to move up and down. At this time, the drive motor 34 is activated, which can drive the rotating rod 35 to rotate, which in turn can drive the sliding rod 37 to slide on the inner wall of the annular groove 38, which can then drive the rotating plate 36 to move to the appropriate position. At this time, activating the hydraulic telescopic rod 32 allows the sealing block 310 to seal the bottom of the valve pipe 2.

[0061] When liquid is discharged, the impact force of the liquid can drive the rotating plate 53 to rotate, which in turn drives the auxiliary rotating rod 52 to rotate. At this time, the torsion spring 55 deforms. At the same time, when liquid is not discharged, the reaction force of the torsion spring 55 causes the rotating plate 53 to return to its original position, and works with the rubber ring plate 54 to seal the inner wall of the valve pipe 2.

[0062] While embodiments or examples of this disclosure have been described with reference to the accompanying drawings, it should be understood that the above embodiments are merely exemplary embodiments or examples, and the scope of this utility model is not limited by these embodiments or examples, but only by the granted claims and their equivalents.
