英文摘要	In order to improve a gasoline pump's small refueling cavity, and the whole pump system vibration and noise problem, a relief valve three-dimensional model for the internal flow field was established according to its structure and parameters. The flow field of the relief valve was studied with the computational fluid dynamics software Fluent, the moving mesh grid technology UDF was used to study the valve's dynamic characteristics. Through analysis, it was shown that the relief value spool ossillation due to the flow fluctuation causes the pump system vibration and noise. To improve the value's dynamic behavior, the fit clearance between the spool and the value body was optimized, the effect of the girth type size δ on the dynamic behavior of the relief value was analyzed. The results showed that when the fit clearance size δ is equal to 0.1mm, the relief value motion is more gentle, the flow fluctuation drops. The test results indicated that when δ is in the range of 0.09~0.1mm, the noise of the relief value drops from 85 dB (A) to 70dB (A). Comparing the simulation results with the test ones, the feasibility of the proposed method was verified. The study results provided a reference for further studying.
