摘　　要：为了解决加油枪出油流速过快，在油气回收系统运行中真空泵构件等磨损，使真空泵回气量大大降低，导致气液比测试不合格的问题，通过分析气液比的影响因素和油气回收的实际状况，研发了一种在加油枪与油气回收管连接部位加装油气回收型加油枪限流板，经改进的第二代限流板可对加油流速进行有效控制，在气液比控制在1．0—1．2的情况下，使加油枪气液比控制合格，提高了油气回收效果。Gas- liquid ratio test is one of the important acceptance indexes of oil vapor recovery system in gas station,which is related to the operation effect of oil vapor recovery,and needs to be assessed on a regular basis. At present,the oil flow rate out of refueling gun is too fast,in case of constant volume of gas return of the vacuum pump,the results of gas-liquid ratio test would not be qualified. In view of the above problems,through the analysis of the refueling operation characteristics of gas station,combining with the actual situation of oil vapor recovery,a flow limiting plate of refueling gun for oil vapor recovery is developed,which can effectively control the flow rate of refueling,ensure the qualified control of gas- liquid ratio and oil vapor recovery effect.
