Abstract
This invention relates to a diversion valve for a liquid metering arrangement including a liquid meter, a sampling chamber and a sub-sampler. The diversion valve has a first position allowing liquid to flow normally to the meter, sampling chamber and sub-sampling chamber. The diversion valve has a second position wherein a major proportion of the flow of a cleaning liquid is diverted through the valve and into the sampling chamber for cleaning-in-place to be effected. A smaller proportion of the cleaning liquid is allowed past the diversion valve for cleaning-in-place of the remaining components of the metering arrangement.
Claims7
A diversion valve for use in a liquid metering arrangement, said valve having a liquid flow control means positionable within a liquid flow line to control the flow of liquid therepast, said flow control means movable between a first position providing substantially no obstruction to liquid flow through said flow line, to a second position at which a substantial proportion of liquid flowing in said flow line is diverted into and through a body of said valve, while a smaller proportion of said liquid is still permitted to flow past said flow control means, said valve body being rotatably mounted in a housing having a liquid outlet port therein, said valve body being rotatable with said flow control means, said valve body having a liquid outlet means in liquid flow connection with said outlet port when said flow control means is in second position but which connection is closed off when said flow control means is in said first position.
A liquid metering arrangement including a liquid sampler chamber having a connection to said liquid flow line and a second connection to a liquid flow line through a diversion valve, said diversion valve having a liquid flow control means positionable within said liquid flow line to control the flow of liquid therepast, said flow control means movable between a first position providing substantially no obstruction to liquid flow through said flow line, to a second position at which a substantial proportion of liquid flowing in said flow line is diverted into and through a body of said valve, while a smaller proportion of said liquid is still permitted to flow past said flow control means, said valve body being rotatably mounted in a housing having a liquid outlet port therein, said valve body being rotatable with said flow control means, said valve body having a liquid outlet means in liquid flow connection with said outlet port when said flow control means is in second position but which connection is closed off when said flow control means is in said first position.
