Valve for a pressure container

Abstract

A valve for a keg of beer comprises a neck ring to be secured to the container and an inner part formed with a valve member, which fits an opening of the neck ring. A locking mechanism functions to lock the inner part in the neck ring, and a sealing ring forms a seal between the inner part and the neck ring at the location of opposite seat portions in the neck ring and the inner part. The inner part and the neck ring are provided with mutually cooperating coupling mechanisms, which, after the locking mechanisms have been released, provide for the removal of the inner part from the neck ring in two steps, wherein pressure relief takes place in the first step via at least one pressure relief opening. The pressure relief opening is formed through the wall of the neck ring, at a location a small distance above the seat portion in the neck ring, so as to effect a reliable pressure relief.
