Title:
METHOD AND CONSTITUTION FOR FILLING VALVE
Document Type and Number:
Japanese Patent JPS63232104
Kind Code:
A
Abstract:
On filling of e.g. liquid products into packing containers via a filling pipe it is of great importance that the valve should be capable of interrupting completely and effectively the flow of contents, since otherwise after-dripping product may soil the outside of the packing container and hinder the formation and sealing of the top of the same. Contents of high viscosity or those containing particles cause particular difficulties, since such materials easily stay behind on the outside of the valve and after the closing of the valve tend to drip onto the packing container. In one arrangement for a filling valve on a packing machine the after-dripping is prevented in that the outside surfaces of the valve which can come into contact with the contents are cleaned with the help of a pressure fluid during operation of the machine. To make this possible an arrangement in accordance with the invention comprises a filling valve 7 whose valve body 13 is provided with a channel 9 for the supply of pressure fluid and an outlet opening 15 situated at the lower end of the valve body 13 which conducts the pressure fluid and causes it to flow along the underside of the valve body so that any residues of the contents are effectively flushed away.
