TESTING METHOD OF WORKABILITY OF CHECK VALVE |
摘要 |
<p>A method of testing the operability of check valves having a pivotal closure disk wherein a check valve is provided having a valve body and first sealing member of nonmagnetic material and a pivotal closure disk and second sealing member of magnetic material, and a magnetic field is applied in a direction which causes the closure disk to move away from the first sealing member. The attraction between the magnetic field generator and the closure disk is measured to determine the relative position of the closure disk to the first sealing member and thus the operability of the valve.</p> |
