SYSTEM FOR REGULATION AND CONTROL OF WATER PRESSURE AND FLOW RATE IN A HIGH PRESSURE WATER APPLICATION

摘要

A water bypass valve and system for regulation and control of water pressureand waterflow rate in high pressure water applications having a water pressure safetyrelief valve.An operator may select a desired water pressure setting in an operatorinterface. Thewater system may be controlled by a computer processor that receives pressuredata froma transducer in a high pressure discharge line and a speed sensor at a waterpump driveshaft. The water bypass valve, controlled by the computer processor, mayregulate waterflowing back to the water supply tank, allowing the safety relief valve toremain closedover a wide range of water pump operating speeds.
