Oil gas recovery quick connector for bottom-mounted filling system

The utility model discloses an oil gas recovery quick connector for a bottom-mounted filling system, which comprises a valve body (1), a valve core (8) and three handles (3) fixedly arranged on the valve body (1) through pins (2), and is characterized in that the three handles (3) are arranged in a regular triangle shape; a sealing gasket (4) and a first O-shaped ring (5) are arranged between the valve body (1) and the valve element (8), and the sealing gasket (4) is arranged on the plane of a movable ring (6). By optimizing the structure of the oil and gas recovery quick connector, the sealing surface is kept parallel and stable when the oil and gas recovery quick connector is connected with a tank car gas phase connector and is always in a compressed state, and leakage is thoroughly eliminated. 本实用新型公开了一种下装式灌装系统用油气回收快速接头，包括阀体(1)、阀芯(8)、通过销子(2)固定设置在阀体(1)上的把手(3)，其特征是，所述把手(1)为3个呈正三角形布置的把手；所述阀体(1)和阀芯(8)之间设有密封垫片(4)和第一0型圈(5)，所述密封垫片(4)设置在可活动的动环(6)平面上。本实用新型通过优化油气回收快速接头结构，使其与罐车气相接头连接时密封面保持平行、稳固，且始终处于压紧状态，彻底消除了泄漏。
