Title:
ABRASION TEST METHOD AND ABRASION TEST DEVICE OF RING VALVE FOR COMPRESSOR
Document Type and Number:
Japanese Patent JP2023058876
Kind Code:
A
Abstract:
To provide an abrasion test method and an abrasion test device of a ring valve for a compressor, capable of accurately evaluating abrasion resistance of the ring valve.SOLUTION: An abrasion test method of a ring valve for a compressor comprises: a step (S11) of holding the ring valve for the compressor inclined with respect to a simulation valve seat simulating the valve seat for the compressor so that a part of a one-sided surface of the ring valve in a circumferential direction is in one-sided contact with the simulation valve seat; and a step (S15) of moving the ring valve relative to the simulation valve seat so that a one-sided contact portion of the one-sided surface in one-sided contact with the simulation valve seat slides against the simulation valve seat, and the one-sided contact portion of the one-sided surface changes in the circumferential direction.SELECTED DRAWING: Figure 6
