Double valve
The invention relates to a double valve with a valve housing ( 1 ), for housing two double-headed actuators ( 30, 31 ), whereby the double head actuators have differing head diameters ( 12, 13 ) and the flow of a fluid through the both actuators ( 30, 31 ) in the valve housing ( 1 ) is identical. The valve housing ( 1 ) is of one-piece design and a drive function for both actuators ( 30, 31 ) is not connected to the inner volume of the valve housing ( 1 ) with fluid flowing therein.
1. A double valve comprising a valve housing ( 1 ) for receiving two serially connected double-disk actuators ( 30 , 31 ), wherein the double-disk actuators have different disk diameters ( 12 , 13 ) and the afflux flow by a fluid to the two actuators ( 30 , 31 ) in the valve housing ( 1 ) is identical, characterised in that the valve housing ( 1 ) is of a one-piece configuration and that a drive function of the two actuators ( 30 , 31 ) is not connected to the internal space of the valve housing ( 1 ), through which space the fluid flows.
2. A double valve as set forth in claim 1 characterised in that the drive function of the two double-disk actuators ( 30 , 31 ) is effected from the same side of the valve housing ( 1 ).
3. A double valve as set forth in claim 1 characterised in that the drive function of the two double-disk actuators ( 30 , 31 ) is flange-mounted to the valve housing ( 1 ).
4. A double valve as set forth in claim 1 characterised in that the valve housing is sealingly closed by covers ( 9 ) on the drive side and by covers ( 5 ) on the underside.
5. A double valve as set forth in claim 1 characterised in that at the outside the valve housing ( 1 ) is of such a configuration that at least one flange ( 18 , 24 ) can be mounted.
6. A double valve as set forth in claim 5 characterised in that the flange is a universal flange ( 18 ) or an ignition gas flange ( 24 ).
7. A double valve as set forth in claim 6 characterised in that a universal flange ( 18 ) and an ignition gas flange ( 24 ) are arranged at the outside of the valve housing ( 1 ).
8. A double valve as set forth in claim 7 characterised in that depending on the respective direction of installation of the valve housing ( 1 ) the universal flange ( 18 ) and the ignition gas flange ( 24 ) are arranged on different sides of the valve housing ( 1 ).
