Description

Technical Field

[0001] The utility model relates to the technical field of filling valves, in particular to a filling valve body capable of preventing blocking. Background Art

[0002] The filling valve is a switch valve that accurately and quantitatively controls the flow rate. It is widely used in food, packaging, petrochemical, metallurgy, painting, vehicles, printing and dyeing machinery. The filling valve adopts a lightweight design, exquisite appearance, compact structure, excellent performance, and is famous for its fast filling speed, convenience, flexibility, precision and stability.

[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 to a position higher than the liquid inlet pipe, the liquid (such as beverage) in the liquid inlet pipe will flow through the accommodating channel and the bottom port of the filling valve body to the container below.

[0004] However, this type of filling valve has some shortcomings in actual use: after the filling valve is used, some beverage residue will accumulate on the inner wall of the bottom liquid outlet of the filling valve accommodating channel. Over time, dust and impurities in the air will adhere to the beverage residue. When the beverage residue dries, these dust and impurities will adhere to the inner wall of the bottom liquid outlet of the filling valve. Long-term accumulation can easily cause blockage at the bottom liquid outlet of the filling valve. Therefore, we propose a filling valve body that can prevent blocking to solve the above problems.

The other ends of the plurality of mounting rods 6 are fixedly mounted with the same circular plate 7. The circular plate 7 is fixedly connected to the driving member 8, and the driving member 8 is supported by the supporting mechanism.

[0024] Furthermore, the elastic connection mechanism includes a swivel 12 and a spring 13. The swivel 12 is rotatably installed in the swivel groove 11, one end of the spring 13 is fixedly installed on the top side of the swivel 12, and the other end of the spring 13 is fixedly installed on the bottom side of the lifting plate 9. When the driving member 8 drives the lifting plate 9, the valve stem 10 and the valve core 3 to move upward, the spring 13 is subjected to force to deform and stretch.

[0025] Specifically, the rotating groove 11 is arranged in a convex structure, the rotating ring 12 is adapted to the rotating groove 11, and a gap is arranged between the lifting plate 9 and the rotating ring 12 and the plurality of mounting rods 6, so that the staff can hold the lifting plate 9 and the rotating ring 12, so as to realize the screwing adjustment of the lifting plate 9 and the rotating ring 12.

[0026] Furthermore, a liquid inlet pipe 14 is provided on one side of the filling valve body 1. The liquid inlet pipe 14 is inclined and communicated with the filling valve body 1, so that the liquid can enter the filling valve body 1 through the liquid inlet pipe 14 and then flow from the liquid outlet 2 to the container below the filling valve body 1.

[0027] Furthermore, an annular groove 15 is provided on the outer surface of the valve core 3, and a sealing ring 16 is provided in the annular groove 15. The sealing ring 16 is sealed against the inner wall of the filling valve body 1.

At this time, the spring 13 is deformed and stretched by force. When the conical bottom end of the valve core 3 moves up to a position higher than the liquid inlet pipe 14, the liquid in the liquid inlet pipe 14 flows into the container below the filling valve body 1 through the liquid outlet 2 on the filling valve body 1; when it is necessary to clear the impurities blocked at the liquid outlet 2 of the filling valve body 1, the staff adjusts the valve core 3 to move downward so that the conical spiral leaf 4 on the conical surface of the bottom end of the valve core 3 fits on the filling valve body. 1, at this time, the bottom end of the conical spiral leaf 4 on the valve core 3 extends out of the liquid outlet 2. After that, the staff rotates the rotating ring 12 and the lifting plate 9 to drive the valve stem 10 and the valve core 3 to rotate. The conical spiral leaf 4 on the valve core 3 continuously rotates to scrape the impurities adhering to the conical inner wall at the bottom end of the filling valve body 1, so that the scraped impurities are discharged to the outside through the liquid outlet 2 of the filling valve body 1, so as to clear the liquid outlet 2 of the filling valve body 1, thereby reducing the blockage of the liquid outlet 2 at the bottom end of the filling valve body 1.
