Oil collection, ball receiving and dosing type integral device

The invention provides an oil collection, ball receiving and dosing type integral device, which comprises a skid seat, an oil inlet valve assembly, a ball receiving cylinder, a dosing tank, a metering pump and an explosive-proof junction box, wherein the oil inlet valve assembly, the ball receiving cylinder, the dosing tank, the metering pump and the explosive-proof junction box are fixedly arranged on the skid seat, the explosive-proof junction box is electrically connected with the ball receiving cylinder, the dosing tank and the metering pump, the oil inlet valve assembly consists of a ball receiving control gate valve and a purge control gate valve which are serially connected by a pipeline, the purge control gate valve is connected with a station external purge outlet through a purge manifold, the ball receiving control gate valve is connected with an inlet of the ball receiving cylinder through a liquid inlet manifold of a well field, an outlet of the ball receiving pipe is connected with an outlet pipeline of the device, an inlet of the dosing tank is connected with an inlet pipeline of the dosing tank, an outlet of the dosing tank is connected with an inlet of the metering pump through an outlet pipeline of the dosing tank, and an outlet of the metering pump is connected with an outlet pipeline of the device through an outlet pipeline of the metering pump. The oil collection, ball receiving and dosing type integral device has the advantages that the structure is simple; the skid-mounted assembly of the oil inlet valve assembly, the ball receiving cylinder, the dosing tank and the metering pump is realized, so the production and installation period is greatly shortened, the land occupation area is saved, and the investment is reduced.
