Modified three-chamber separation valve

摘要

The system separating valve has three chambers and has a number of non-return valves. It also includes unloading valves which may release the pressure (Pi) in the middle zone of the valve. Fluid, especially drinking water, may enter the entrance (1) of the valve at a first high pressure (P1) and then passes through a control valve from the first chamber to a second chamber at an intermediate pressure (Pi). Water then may flow through a further valve into an exit region at a third low pressure (P2).
