Spray appliance for sealing agents

摘要

The appliance has a pressurised container with a main body and a removable cover to seal it hermetically via a releasable connection. A portable vessel is fitted into the container, and the cover has a connection for compressed air intake and a rising pipe. The rising pipe projects into the vessel interior, and a spray line is connected to it outside the pressurised container. The container consists of a steel tube with a base welded to it at one end and a flange at the other end. The connection between container body and cover is a screw connection with concentric screws engaging in flange and cover, via an elastic rubber sealing ring.
