The Test Investigation for Main Working Performance of Double Seats Valve

The double seats valve was used in steam turbine unit very extensively.For better using the double seats valve,the characteristics of the valve such as the flow passage capability,the pressure loss,the lifting force and the working stability were test investigated in the present paper.Some main working performance of the double seats valve was got by analyzed the test results,and it could apply some valuable references for the practice application of the double seats valve.
