摘要
The timed flow reverser for single-string pipelines reverses the flow by means of two three-way valves. The flow reversal takes place at unspecified time intervals, at which the two three-way valves are activated by means of two setting drives, which may act simultaneously or alternately on them with an opening or closing pulse.
