Single pipe connection for gas and fluid flow to liquid tank - has switch valve with coaxial channels for tank interior and spray head

摘要

The automatic switch valve which is associated with the connecting pipe leading into the top of the tank for the selective supply of gaseous flow medium or fluid cleaning agent has on its outlet side coaxial channels which are led jointly to a single connection in the top of the tank from where one of the channels is guided out through the connection into the interior of the tank and to the spray head. The switch valve has a valve body which shuts off one of the coaxial channels when the cleaning fluid is supplied and the switch valve itself is pref. flanged directly onto the connection in the tank top so that the connecting pipe ends directly at the valve which is now set between the connecting pipe and the connection.
