The invention relates to the oil industry and can be used in the system of collection and treatment of oil, gas and water industries.

The problem of separating the liquid stream into parts occurs when the measurement of the production wells connected in parallel multiple devices (separators, clarifiers, etc).

It is known device [1] which divides the stream into multiple streams. The main element of this device is a disk having a through hole, which is installed across the flow of fluid in the pipeline. It is believed that when the fluid flow is divided equally by the number of holes in the disk. One stream is allocated and is available for measurement. Obviously, when the may not be equal to the flow rate of the jet, not isolated from the General flow.

Known distribution system of gas and liquid flows through the separation apparatus [2] At the same time as the dispenser is used the pipe with bends along the length to select separately the liquid and gas. You want the piping to drain the liquid and gas separators have the same cross-section, length, valves and geometric position in space in order to ensure the equality of the total hydraulic resistance during the movement of liquid and gas. However, the constructive solution of the distributor is not possible to fulfill all these requirements.

The objective of the proposed technical solution is the provision of distribution multicomponent flow in equals flow part.

This object is achieved in that known device is provided with a mixing chamber, made with a spherical bottom is symmetrical about the vertical axis. In the mixing chamber is mixed multicomponent flow due to the energy of the downward jet, the guide apparatus of the mixing chamber provides a symmetrical movement of the stream by the number of lateral pipelines entering the gas tube collapse of mallaca part of the mixing chamber symmetrically at equal distances from the walls of the chamber and the entrance of the inlet pipeline and have a vertical portion to provide an ascending stream which on one level is transferred in the downward flow through the overflow device in the form of a knee with 180aboutthe upper part of which is connected in one common pipeline that delivers on the rising area of the discharge piping equal pressure drops.

Equal to the pressure drop when other conditions are equal (equal in diameter and length of piping, equal sign, the same liquid) takes place only at equal flow in this pipe section. On the crossing upstream to downstream in the presence of a gas cap in the upper part of the pipeline occurs gravity section, i.e. the section of pipe with a partial cross-section of the fluid in the pipeline. After the gravity of the plot on the descending section of each outlet pipe is set some the height of the liquid column, depending on the flow resistance in the discharge piping. The maximum height of the liquid column will correspond to the discharge pipeline, where maximum resistance to flow.

The proposed device provides a mixture of multicomponent flow and divide it into equal parts for consumption.

od 1, the mixing chamber 2, the guide device 3, a fine mesh 4, the cone 5, a plot of the discharge parts of the flow pipes 6, total pipe 7 for removal of gas, gravity sections 8 taps parts of the stream.

The device operates as follows.

Multicomponent stream (production wells for oil, gas, water) flows through the pipe 1 into the mixing chamber 2. A guiding apparatus with sectors on the number of taps of the parts of the flow causes the separation of the flow on the side at the exit of the inlet pipeline and provides identical vortices, mixing flow for each outlet, mallacoota mesh divides into small pieces bubbles of gas, and the cone directs the gas to the vertical lateral parts of the stream.

Under the pressure of the flow of the liquid rises in an ascending vertical sections of taps. The allotment for each part of the stream is made the same way. The beginning of all branches located in the mixing chamber at the same level and when the pressure P1and the ends of the branches are at the same level and when the pressure P2as reported total inlet to gas outlet.

Vertical upward part of all branches ends overflow device, after kotorom section. After gravity section of the descending part of the taps have different fluid level in the branches depending on the value of the hydraulic resistance in each row. Gravity plot is saved in a wide range of flow rate due to the formation of a gas cap in the upper part of the branches.

This ensures that the division of the flow into equal parts regardless of the value of the hydraulic resistance in different branches, which allows to solve the problem of measuring large production wells cheaper compact measuring units and ensuring normal operation of the parallel-connected devices (separators, clarifiers, and so on).

A DEVICE for SEPARATING the LIQUID STREAM into EQUAL PARTS containing lead pipe, valve, discharge piping, characterized in that the dispenser is made in the form of the mixing chamber, which is equipped with a fine-meshed net, cone, and opposite the inlet pipeline symmetrically installed a guiding apparatus, the outlet pipe is made to rotate 180oand with gravity flow section and communicated with the common inlet to the gas outlet.
