| 摘 要： | 提出了一种基于磨料浆体射流技术的针阀体喷孔研磨技术。该技术利用针阀体喷孔的节流作用使射流发生,靠浆料的研磨作用来去除针阀体内流道毛刺,对喷孔孔口进行倒角,以提高其流量系数。加工时,通过流量控制系统实时监测、控制针阀体的实时流量与终止流量,来控制其流量离散度。实际加工实验表明,该技术可以提高针阀体流量系数到0.85左右,同批针阀体流量离散度控制在±1%以下,达到国外同类技术的先进水平。

| Abstract: | The grinding technology of injector valve based on abrasive suspension jet is presented. The jet nozzle is replaced by the injector valve for the grinding process . By deburring and radiusing the intersecting passage of the injector valve with the abrasive suspensionresultsin a high flow coefficient . During the grinding process ,the actual through flow rate is compared to a predetermined reference through flow rate . When the two coincide ,the processis brought to an end in order to calibrate the flow tole... |
