Fruit juice filling valve

Abstract

The invention relates to a filling valve, in particular to a fruit juice filling valve. A cleaning device is arranged at one end of a liquid guide valve seat and a valve seat head. An inner cavity of the valve seat head communicates with a material cavity to form a flow guide cavity. The cleaning device comprises a rotary pipe, a liquid storing tank and spraying heads, wherein the rotary pipe is located in the flow guide cavity and rotationally connected to the liquid guide valve seat with a valve rod as the rotary axis; a cleaning channel is formed between the outer wall of the rotary pipe and the inner wall of the flow guide cavity; forward-rotation annular ribs are disposed on the inner wall of the rotary pipe; backward-rotation impellers are disposed on the outer wall of the rotary pipe; the liquid storing tank is provided with an air outlet, a liquid inlet pipeline, a recycling pipeline and a liquid inlet cover; the air outlet is formed in the top of the liquid storing tank; the liquid inlet pipeline communicates with the liquid storing tank and the cleaning channel; the recycling pipeline communicates with the inner cavity of the valve seat head and the liquid storing tank; both the liquid inlet pipeline and the recycling pipeline are provided with valves; and the spraying heads are connected with the cleaning channel and arranged on the inner wall of the rotary pipe or in the material cavity. The invention aims to provide the filling valve of which an interior cavity can be comprehensively cleaned.

AI Technical Summary

Problems solved by technology

The problem existing in the prior art is: due to the external cleaning device, the distance between the cleaning liquid outlet pipe and the cleaning liquid inlet pipe is relatively close due to the volume limit of the structure, and the possible problem is that after the cleaning liquid flows out from the cleaning liquid inlet pipe, The cavity of the entire quantitative filling valve cannot be cleaned, and then it flows back into the cleaning device from the cleaning outlet pipe

This results in insufficient cleaning of the dosing filling valve

Especially for beverages involving fruit juice, it is easy to accumulate on the inner wall of the filling valve, and it cannot be cleaned thoroughly only by washing with detergent
