Description

Technical Field

[0001] The utility model relates to the technical field of filling valves, in particular to a filling valve body with adjustable filling volume. Background Technique

[0002] A filling valve is a switch-type valve for precisely quantitatively controlling the flow rate, and it is widely used in machinery such as food, packaging, petrochemical, metallurgy, painting, vehicles, and printing; the filling valve adopts a light design, with a beautiful appearance, a compact structure, and excellent performance.

[0003] There is a filling valve with a back-suction function (its authorization announcement number is: CN216102892U), which drives the valve core to move upward through a driving member. When the valve core moves upward to a position higher than the liquid injection pipe, the liquid (such as beverage) in the liquid injection pipe will flow through the accommodating channel through the bottom port of the filling valve body to the container below.

[0004] In order to better meet the market demand, manufacturers often fill beverages into packaging bottles of different capacities for sale. However, there are some deficiencies in the actual filling process of this kind of filling valve: when filling beverages, this kind of filling valve cannot adjust the filling volume inside the filling valve, so it is difficult to fill packaging bottles of different capacities, reducing the applicability of the filling valve; therefore, we propose a filling valve body with adjustable filling volume to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a filling valve body with adjustable filling volume to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A filling valve body with adjustable filling volume includes a filling valve body. A valve core is arranged inside the filling valve body. One end of a valve rod is fixedly installed at the top end of the valve core. The other end of the valve rod movably penetrates outside the filling valve body. A liquid injection groove is formed inside the valve rod. One end of the liquid injection groove is connected to a liquid injection pipe. A filling opening mechanism for the valve rod is arranged on the top side of the filling valve body. A threaded groove is formed on the outer surface of the filling valve body. A threaded cylinder is threadedly installed in the threaded groove. A rotating ring is rotatably installed on the top side of the threaded cylinder. A piston disk is arranged inside the filling valve body. The rotating ring and the piston disk are connected by a connecting mechanism. Two capacity display mechanisms are respectively arranged on the outer side wall of the filling valve body.

[0008] Preferably, the filling opening mechanism includes a frame body, a driving member, and a driving rod. A frame body is fixedly installed on the top side of the filling valve body. A driving member is fixedly installed on the top side of the frame body. The output end of the driving member is fixedly installed with a driving rod. One end of the driving rod is fixedly installed at the top end of the valve rod. By starting the driving member, the driving rod drives the valve rod and the valve core to move upward, facilitating the beverage liquid to flow out through the gap between the valve core and the liquid outlet end of the filling valve body, and then filling it into the filling bottle below the filling valve body.

[0009] Preferably, both the threaded cylinder and the rotating ring are sleeved on the filling valve body. The rotating ring is located above the threaded cylinder, facilitating the upward and downward adjustment of the rotating ring by screwing the threaded cylinder upward or downward.

[0010] Preferably, the connecting mechanism includes an L-shaped connecting plate and a connecting rod. Two L-shaped connecting plates are respectively fixedly installed on the top side of the rotating ring. One end of two connecting rods is respectively fixedly installed on the top side of the piston disc. The other ends of the two connecting rods both extend out of the filling valve body movably and are fixedly connected to the corresponding L-shaped connecting plates. When the threaded cylinder is screwed, it synchronously drives the rotating ring, the two L-shaped connecting plates, the two connecting rods, and the piston disc to move upward or downward.

[0011] Preferably, the inner wall of the L-shaped connecting plate is arranged in an arc structure, and the arc-shaped inner wall of the L-shaped connecting plate fits on the outer wall of the filling valve body, facilitating the sliding of the L-shaped connecting plate on the outer wall of the filling valve body.

[0012] Preferably, a first sealing ring is arranged on the valve core, and the first sealing ring is hermetically attached to the inner wall of the liquid outlet end of the filling valve body. Second and third sealing rings are respectively arranged on the piston disc. The second sealing ring is hermetically attached to the inner wall of the filling valve body, and the third sealing ring is hermetically sleeved on the valve rod, facilitating the improvement of the sealing performance of the filling capacity space in the filling valve body.

[0013] Preferably, the capacity display mechanism includes a side groove and capacity scales. A side groove is opened on the outer side wall of the filling valve body. The inner wall of the side groove is provided with capacity scales. The bottom ends of the threaded cylinder and the piston disc are kept horizontal, and the bottom end of the threaded cylinder is kept horizontal with the value of the corresponding capacity scale. Since the bottom ends of the threaded cylinder and the piston disc are kept horizontal, by observing the value corresponding to the capacity scale horizontally aligned with the bottom end of the threaded cylinder, the filling amount in the filling valve body at this time can be known.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The filling valve body with adjustable filling volume is provided with a movable and adjustable piston disk inside the filling valve body. By screwing the threaded cylinder to an appropriate height on the filling valve body, the height of the piston disk inside the filling valve body can be adjusted simultaneously, thereby indirectly adjusting the filling volume inside the filling valve body, facilitating the filling of packaging bottles with different capacities, and improving the applicability of the filling valve body.

A thread groove 9 is opened on the outer surface of the filling valve body 1, and a thread cylinder 10 is threadedly installed in the thread groove 9. A rotating ring 11 is rotatably installed on the top side of the thread cylinder 10. A piston disk 13 is arranged inside the filling valve body 1. The rotating ring 11 and the piston disk 13 are connected by a connecting mechanism. Two capacity display mechanisms are respectively arranged on the outer side wall of the filling valve body 1.

[0025] Further, the filling opening mechanism includes a frame body 6, a driving part 7 and a driving rod 8. A frame body 6 is fixedly installed on the top side of the filling valve body 1. A driving part 7 is fixedly installed on the top side of the frame body 6. The output end of the driving part 7 is fixedly installed with a driving rod 8. One end of the driving rod 8 is fixedly installed at the top end of the valve rod 3. By starting the driving part 7, the driving rod 8 drives the valve rod 3 and the valve core 2 to move upward, facilitating the beverage liquid to flow out through the gap between the valve core 2 and the liquid outlet end of the filling valve body 1, and then filling it into the filling bottle below the filling valve body 1.

[0026] Further, both the thread cylinder 10 and the rotating ring 11 are sleeved on the filling valve body 1, and the rotating ring 11 is located above the thread cylinder 10, facilitating the upward and downward adjustment of the rotating ring 11 by screwing the thread cylinder 10 upward or downward.

[0027] Further, the connecting mechanism includes an L-shaped connecting plate 12 and a connecting rod 14. Two L-shaped connecting plates 12 are respectively fixedly installed on the top side of the rotating ring 11. One end of two connecting rods 14 is respectively fixedly installed on the top side of the piston disk 13. The other ends of the two connecting rods 14 both movably extend outside the filling valve body 1 and are fixedly connected with the corresponding L-shaped connecting plates 12. When the thread cylinder 10 is screwed, it synchronously drives the rotating ring 11, the two L-shaped connecting plates 12, the two connecting rods 14 and the piston disk 13 to move upward or downward.

[0028] Specifically, the inner wall of the L-shaped connecting plate 12 is arranged in an arc structure, and the arc inner wall of the L-shaped connecting plate 12 fits on the outer wall of the filling valve body 1, facilitating the sliding of the L-shaped connecting plate 12 on the outer wall of the filling valve body 1.

[0029] Specifically, a first sealing ring 15 is arranged on the valve core 2, and the first sealing ring 15 is hermetically fitted on the inner wall of the liquid outlet end of the filling valve body 1.

The bottom ends of the threaded cylinder 10 and the piston disk 13 are kept horizontal, and the bottom end of the threaded cylinder 10 is horizontal with the value of the corresponding capacity graduation 19. Since the bottom ends of the threaded cylinder 10 and the piston disk 13 are kept horizontal, by observing the value corresponding to the capacity graduation 19 that is horizontally aligned with the bottom end of the threaded cylinder 10, the filling amount in the filling valve body 1 at this time can be known.

[0031] During use: When the filling valve body 1 is filling, the operator rotates the threaded cylinder 10 to make the threaded cylinder 10 move spirally upward in the threaded groove 9, thereby driving the rotating ring 11, two L-shaped connecting plates 12, two connecting rods 14 and the piston disk 13 to move upward, so as to realize the adjustment of the filling capacity in the filling valve body 1. Since the bottom ends of the threaded cylinder 10 and the piston disk 13 are kept horizontal, by observing the value corresponding to the capacity graduation 19 that is horizontally aligned with the bottom end of the threaded cylinder 10, the filling amount in the filling valve body 1 at this time can be known. By rotating the threaded cylinder 10 to an appropriate height on the filling valve body 1, the filling amount in the filling valve body 1 can be indirectly adjusted, which is convenient for filling packaging bottles of different capacities and improves the applicability of the filling valve body 1; during filling, the beverage liquid is injected into the filling valve body 1 through the liquid injection pipe 5 and the liquid injection groove 4 until the filling amount in the filling valve body 1 is full of the beverage liquid. After that, by starting the driving member 7, the driving rod 8 drives the valve rod 3 and the valve core 2 to move upward, which is convenient for the beverage liquid to flow out through the gap between the valve core 2 and the liquid outlet end of the filling valve body 1, and then be filled into the packaging bottle below the filling valve body 1.
