Abstract:
Aiming at the problem of the wear of the ball-end of the main spring seat of the pressure reducing valve, the failure mechanism of the ball-end of the pressure reducing valve was analyzed by the method of combining simulation and experiment.Stress and strain of the steel 2Cr13 ball-end with different hardness combinations were calculated, and results indicate that the existing structure has the problem of super high stress.The wear of paired metal materials was studied, from the improvement ideas of reducing contact stress and avoiding adhesion wear, the improvement measures were proposed.Through the verification of wear comparison test, the final improvement plan of the pressure reducing valve was determined.After large numbers of the pressure reducing valve test, the problem of ball wear has been completely solved, which verifies the effectiveness of the improvement measures.Under the premise that the contact stress does not exceed the yield strength of the material, wear is closely related to the crystal structure of the material.The titanium alloy has certain advantages as the friction pair material.
