Description

A mechanical hot filling valve

technical field

The invention relates to the field of beverage hot filling, in particular to a mechanical hot filling valve.

Background technique

PET hot filling is widely used in China, and mechanical valves are used. There are large dead angles between the moving parts and static parts of these valves, which are not easy to clean. Due to the high sugar content of hot-filled beverages, if the valve cannot be cleaned thoroughly, fouling will occur for a long time, which will affect the quality of the filled product.

Contents of the invention

The technical problem to be solved by the present invention is to provide a mechanical hot filling valve that can improve the cleaning condition of the mechanical hot filling valve, avoid cleaning dead angles, and achieve no residue.

In order to solve the above problems, the technical solution adopted by the present invention is: relatively movable upper valve body and lower valve body, a filling cavity is formed inside the upper valve body and the lower valve body, and the upper part of the filling cavity is provided with a feeding port. The lower part of the filling chamber is provided with a discharge port, the middle part of the filling chamber is provided with a convex ring, and the middle part of the filling chamber is provided with a valve stem. The outer wall of the flow ring is in conflict with the convex ring. There is a gas return pipe in the middle of the valve stem. A sealing ring made of elastic material is installed in the filling chamber. The two ends of the sealing ring are respectively fixed on the upper valve body and the lower valve body. A slope is formed between the upper valve body and the lower valve body.

The upper end of the sealing ring is stuck in the upper valve body, the lower end of the sealing ring is provided with a T-shaped groove, and the upper wall of the lower valve body is provided with a T-shaped protrusion, and the T-shaped protrusion is clamped in the T-shaped recess. in the slot.

The beneficial effects of the present invention are: due to the addition of a sealing ring at the sliding part of the filling valve, the material flows directly into the filling chamber along the inclined plane during filling, avoiding the dead angle of the dynamic and static parts of the filling valve, making filling, cleaning There is no residue, which improves the quality of the filling product and indirectly improves the efficiency of filling.

Detailed ways

A mechanical heat filling valve of the present invention will be further described in detail through specific embodiments below.

As shown in Figure 1, a mechanical thermal filling valve includes an upper valve body 1 and a lower valve body 2 that can move relatively, and a filling cavity is formed inside the upper valve body 1 and the lower valve body 2, and the upper part of the filling cavity is provided with There is a feed port 3, the lower part of the filling chamber is provided with a discharge port 4, the middle part of the filling chamber is provided with a convex ring 5, and a valve stem 6 is arranged in the filling chamber, and the upper end of the valve stem 6 is connected to the upper valve body 1. connection, the stem 6 is provided with a diversion ring 7, the diversion ring 7 is provided with a diversion hole 8, and the outer wall of the diversion ring 7 conflicts with the convex ring 5, thereby separating the filling cavity into an upper cavity 9 and a In the lower chamber 10, there is a gas return pipe 11 in the middle of the valve stem 6, and a sealing ring 12 made of acid-resistant, alkali-resistant, heat-resistant elastic material is arranged in the filling chamber, and the upper end of the sealing ring 12 is stuck on the upper valve body 1 Among them, the lower end of the sealing ring 12 is provided with a T-shaped groove, and the upper wall of the lower valve body 2 is provided with a T-shaped protrusion 13, and the T-shaped protrusion 13 is clamped in the T-shaped groove, and the sealing ring 12 is in the A smooth slope is formed between the upper valve body 1 and the lower valve body 2 .

The working principle of the present invention is: when filling, the material enters from the feed port 3, flows into the upper cavity 9 along the slope of the sealing ring 12, and at the same time, the lower valve body 2 moves upward, and the sealing ring 12 produces elastic deformation, so that the diversion The diversion hole 8 in the ring 7 communicates with the lower cavity 10, so that the beverage in the upper cavity 9 enters the lower cavity 10 after passing through the diversion hole 8, and finally enters the bottle from the discharge port 4, and the beverage in the bottle The air is discharged from the air return pipe 10. During the entire filling process, the material will not enter the dead angle between the upper valve body 1 and the lower valve body 2, so that there is no residue in filling and cleaning, and the quality of the filled product is improved.

The above-mentioned embodiment only illustrates the principle of the present invention and its effect, and the embodiment of partial use, but is not intended to limit the present invention; It should be pointed out that for those of ordinary skill in the art, without departing from the Under the premise of creating ideas, some modifications and improvements can also be made, which all belong to the protection scope of the present invention.
