<p>A container intended for transporting and discharging aggressive liquids, such as silicon tetrachloride, is closed with a container lid which carries a valve head. The inner surfaces of the container and of the container lid are lined with fluorinated hydrocarbon. The valve head has a valve block which, in valve block drilled holes accommodates valve inserts and is enclosed by a steel jacket which is bolted to the container lid. All the parts which come into contact with the aggressive liquid consist of fluorinated hydrocarbon, so that contact between the aggressive liquid and metal is avoided.</p> |
