Abstract
A valve has a plurality of material inlet ports, a flushing inlet port, and an outlet port each connected to a respective supply of one of last two different liquid materials. A movable valve body in the valve has a passage and is shiftable between a plurality of positions in each of which a respective one of the inlet ports is connected to the outlet port via the passage. A controller moves the valve body between the positions such that, after each time the valve body is in a position connecting one of the material inlet ports to the outlet port and material has passed through the passage, the valve body is moved into a position connecting the passage with the flushing inlet port for flushing out the passage.
Claims3
A system comprising:
- a valve having a plurality of material inlet ports, a flushing inlet port, and an outlet port;
- respective supplies of at last two different liquid materials, the supplies each being connected to a respective one of the material inlet ports;
- a supply of flushing medium connected to the flushing inlet port;
- a movable valve body in the valve, having a passage, and shiftable between a plurality of positions in each of which a respective one of the inlet ports is connected to the outlet port via the passage;
- and
- control means for moving the valve body between the positions such that, after each time the valve body is in a position connecting one of the material inlet ports to the outlet port and material has passed through the passage, the valve body is moved into a position connecting the passage with the flushing inlet port for flushing out the passage.
An apparatus comprising:
- a valve with a plurality of inlets and an outlet, the inlets being connectable to respective material supply containers;
- an actuator having a throughgoing passage and displaceable relative to the inlets to provide a switchable connection between each of the plurality of inlets and the outlet, the throughgoing passage being movable into a communicative connection selectively with a respective one of the various inlets to enable feeding of different materials successively to the outlet;
- and
- a flushing device for flushing the throughgoing passage, the flushing device being connected to a water mains network with the interposition of a pipe disconnecting device.
