Static Regulate System of Power Plant Boiler Safe Valve

The gearing closes valve between the safe valve and the boiler system.The connect system between closes valve and safe valve will be filled with the hydrogen with 1% concentration and 10 MPa pressure.Before boiler working,pull the haulm of safe valve by hydraulic motor set until the safe valve spring.In this process,the power force of hydraulic motor can be measured by a pull sensor.In the meantime,a thermal sensor feels temperature on the safe valve body and a gas sensor with high sensitivity be lining up spirit the hydrogen.Find out that it can output a signal of safe valve open within 0.2 second by researching response character of hydrogen.The data collects to equip a calculation to pull dint here under spring coil pressure,combine the valve petal area of measure,then send out a difference between safe valve and initial expect value.A influence of thermal to spring flexibility has be researched,and have pointed out correct angle of adjust nut at any valve body temperature.
