Valve arrangement for dosage regulation for liquid containers has integrated regulator valve and open/closed valve for compact construction

摘要

The device has a valve housing (2) with passage (2.5) and control cone (3), open/closed valve to drain sludge, and a regulator valve with cone (3.2) for the dosage. The cone has a passage (3.8) with regulator valve seat (3.7), and the regulator valve cone is moveable relative to the control cone. Both cones are moved by a common valve rod (4), which is coupled to the regulator valve cone, and are opened and closed in the same directions. Both passages are in flow connection with the same intake (2.1) and outlet (2.2) of the valve housing.
