Abstract
A water supply system comprising a supply line and a network of consumers, one of which being a monitored consumer who receives the least amount of pressure, a pressure regulation system comprising a pressure reducing valve (PRV) associated with a pilot valve preset to a nominal output pressure and a pressure control system comprising a differential control valve (DCV). A pickup unit is provided for measuring a flow parameter indicative of the pressure at the monitored consumer and emitting a pressure signal to a controller generating in turn a control signal responsive to the pressure signal to activate an actuator of the DCV thereby governing the flow rate through the DCV, so as to obtain desired pressure at the monitored consumer, regardless of altering flow rate through the PRV.
Claims21
A water supply system comprising a supply line and a network of consumers, one of which being a monitored consumer who receives the least amount of pressure, a pressure regulation system comprising a pressure reducing valve (PRV) associated with a pilot valve preset to a nominal output pressure;
- and a pressure control system comprising a differential control valve (DCV) connected in series to said pilot valve;
- a pickup unit for measuring a flow parameter indicative of the pressure at the monitored consumer and emitting a pressure signal to a controller;
- said controller generating a control signal responsive to the pressure signal to activate an actuator of the DCV thereby governing the flow rate through the DCV, so as to obtain desired pressure at the monitored consumer, regardless of altering flow rate through the PRV.
A method for controlling pressure at water supply system comprising a supply line and a network of consumers, one of which being a monitored consumer who receives the least amount of pressure;
- a pressure regulation system comprising a pressure reducing valve (PRV) fitted with a pilot valve preset to a nominal output pressure, a pressure control system comprising a differential control valve (DCV) connected in series to said pilot valve, a flow parameter pickup unit and a controller;
- the method comprising the following steps:
- (i) measuring a flow parameter indicative of the pressure at the monitored consumer and emitting a pressure signal to the controller;
- (ii) generating a control signal by the controller, said control signal being responsive to the pressure signal;
- (iii) activating an actuator of the DCV by the control signal, thereby governing the flow rate through the DCV so as to control flow rate through the pilot valve and to obtain desired pressure at the monitored consumer, regardless of altering flow rate through the PRV.
