For testing and adjusting spring loaded safety and relief valves under full pressure in a built in condition a special process was developed. |
 |
|
|
The physical basic priciple is: P (bar) = F ( N ) / A ( cm^2) ( pressure = force / area)
|
||
<The variable in question is P (set pressure). <The area A is determined from the valve data (averaged seat area). <The variable F is measured directly on the safety valve spindle. |
During the test the system pressure p2 (bar) and the displacement of the valve spindle s (mm) are supplementary recorded. | |
The variables mentioned above are simultaneously processed in a computer. For every tested valve a test report will be handed over to the customer. Our equipment requires a power supply of 220V/50Hz and an axial free space of only 500 mm above the valve spindle. |
