Spigot for a beverage barrel, for pouring and ventilation, has cylindrical outer and inner sections with inner and outer cones to give effective sealing surfaces, and a valve closing action when the flow stops through the spigot

摘要

The spigot for a beverage barrel of tinplate or aluminum or plastics, for pouring and ventilation, has a cylindrical outer section (20) with an inner cone (26) and a cylindrical inner section (22) with an outer cone (28), with their sealing surfaces tightly against each other. A guide and a pull unit (30,31) acts with the outer section to apply an axial pull or push force on the inner section, towards the smaller cone diameter.
