Oil gathering, ball collecting and charging integrated device

The utility model discloses an oil gathering, ball collecting and charging integrated device which comprises a skid-mounted seat, an oil feeding valve group fixed to the skid-mounted seat, a ball collecting barrel, a charging tank, a metering pump and an anti-explosion connection box. The anti-explosion connection box is electrically connected with the ball collecting barrel, the charging tank and the metering pump. The oil feeding valve group is composed of a ball collecting control gate valve and a purge control gate valve, wherein the ball collecting control gate valve and the purge control gate valve are connected in series through a pipeline. The purge control gate valve is connected with a sweep outlet outside a station through a purge gathering pipe. The ball collecting control gate valve is connected with an inlet of the ball colleting barrel through a well field feeding fluid gathering pipe. An outlet of the ball receiving barrel is connected an outlet pipeline of the device. An inlet of the charging tank is connected with an inlet pipeline of the charging tank. An outlet of the charging tank is connected with an inlet of the metering pump through an outlet pipeline of the charging tank. An outlet of the metering pump is connected with a device outlet pipeline through an outlet pipeline of the metering pump. The structure is simple, skid-mounted integration of the oil feeding valve group, the ball collecting barrel, the charging tank and the metering pump is achieved, the production and mounting period can be shortened greatly, the floor area is reduced, and investment is saved.
