加油站的油气回收系统,是将整个加油站在工作流程中挥发出的油气进行回收,再将这些回收到的油气进行物理分离和解析,将油气转化成液体状态储存在油气罐中。油气回收系统由加油机、同轴加油软管、油气回收型加油枪、真空泵、气液比调整器、拉断阀、回气管、埋地油罐、P/V阀等部件组成。系统的工作原理是将加油时产生的油气,在真空泵的作用下,利用加油枪上的回气孔通过回气管回到埋地油罐内,
The gas recovery system of a gas station reclaims the oil and gas which are volatilized from the gas station in the work process. Then, the recovered oil and gas are physically separated and analyzed, and the oil and gas are converted into a liquid state and stored in the oil and gas tank. Oil and gas recovery system consists of tanker, coaxial hose, oil and gas recovery refueling gun, vacuum pump, gas-liquid ratio regulator, pull-off valve, return pipe, buried tank, P / V valve and other components. The working principle of the system is that the oil and gas generated during the refueling is returned to the buried oil tank through the return air pipe through the return air hole on the refueling gun under the action of the vacuum pump,
