Plunger-type quantitative filling valve

Abstract

The plunger type rationing and filling valve has one plunger; one plunger barrel for the plunger to be stretched in and with opening in the lower part; one valve seat in the lower part of the plunger barrel and with material gate in the upper part and corresponding to the opening in the plunger barrel, material outlet in the lower part and inside horizontal channel; and one valve core with one end connected to the operating rod and the other end with material entrance stretched into the horizontal channel in the valve seat and two inside connecting channels, which makes the material gate communicated to the material inlet or the material outlet when the valve core is turned to one of two different positions. The present invention realizes beverage filling by means of the reciprocation of the plunger, and is especially suitable for filling ropy material filling.

Description

1. Technical field [0001] The invention relates to a mechanical filling valve for fluid packaging, in particular to a plunger type quantitative filling valve. 2. Background technology [0002] With the continuous improvement of people's living standards, higher requirements have been put forward for the quality of life, and beverage products have been introduced accordingly. Fruit juice beverages have gradually replaced carbonated beverages because of their good taste and rich nutrition. In recent years, various beverage manufacturers have launched fruit juice beverages containing pulp respectively, which are very popular among consumers. The shape of the pulp in fruit juice beverages containing pulp is fibrous, granular and lumpy, the pulp is suspended in the juice, and the final product is a solid-liquid mixture, which is different from the previous pure liquid in terms of physical form. Drinks make a huge difference. Therefore, the filling of this type of beverage canno...

AI Technical Summary

Problems solved by technology

[0008] 1. When quantitative filling is indirectly realized by equal liquid level filling, due to the volume error of the filling container itself, the actual filling volume error is relatively large after equal liquid level filling, and quantitative filling in the true sense has not been realized. packaging, cannot meet the requirements of commodity calibration, and does not meet the requirements stipulated in the Product Measurement Law and the "Measurement Supervision and Administration of Quantitatively Packaged Commodities";

[0009] 2. Using the principle of gravity filling, it is difficult to fill viscous fluids;

[0010] 3. It is not possible to fill fluids containing particles or massive suspended matter. As mentioned above: the opening and closing valves of various filling valves are sealed with gaskets. The existence of solid pulp will destroy the sealing effect of the gaskets. The reliability of the opening and closing of the valve cannot be guaranteed; at the same time, the mixture of pulp and juice is easy to block the return air pipe and cause the liquid level to be inaccurate;

[0011] 4. There is a filling device installed in the filling tank. The device is soaked in the material, which is not easy to clean, and it will stir the material during operation, which is not conducive to filling.
