The invention relates to the oil industry and can be used in the system with logicheskih the processes of any industry, when it is necessary to divide the fluid flow into equal parts.It is known device  , 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. It is obvious that the conditions of flow of the jet is very different from the conditions for the flow of other streams. Therefore, the flow rate of the jet may not be equal to the flow rate of the jet that are not selected from the total flow.Known distribution system flows of liquid and gas separation devices . The allocator uses a horizontal pipeline with branches along the length of the selection of the separately gas and liquid. 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, this constructive solution to these requirements will is drasti into equal parts for consumption.The task solves the divisor of fluid flow into equal parts containing lead pipe, casing, and the outlet pipe, it is equipped with an exhaust pipe, placed in the enclosure, which is made in the form of a vertical cylinder with a diameter larger than a diameter of the inlet pipe, and the Windows of identical rectangular cross-section on the side, made at the same height as the outlet pipe is made in the form of nozzles attached to the body inclined, when this device is made with the possibility of overflow of fluid flow in pipes through the Windows of rectangular cross-section and maintain the pillars of the liquid in each of the nozzles below the level of the overflow of fluid from the body.The body of the divider has a nozzle in the lower part (supply line) for supplying a total gas-liquid flow, and in the upper - pipe to exhaust gas present in the flow. Inside the body is placed exhaust pipe with holes for removal of free gas from the flow in the upper part of the body.Running Windows in the hull of the divider to drain parts of the stream in the form of a rectangular window allows you to save the cross section of the Windows of constant height that allerona fluid in Windows in the hull of the divider.Perform lateral pipelines as pipes, attached to the body inclined, allows you to increase the cross section of the rectangular window so that it is not less than the circular cross-section pipes, and provide maximum fluid flow through the flow divider. In addition, this embodiment of the outlet portions of the fluid flow nozzle provides a flow of fluid through the thin wall of the body, without creating an additional threshold on the path of movement of parts of the flow, which also contributes to filling with minimal resistance, i.e., the maximum flow rate of the overflow.The divisor of fluid flow into equal parts installed on the estimated height so that each inlet part of the fluid flow tech section is not complete, and further movement of the flow tubes is ensured by the pressure of the liquid column, which is formed below the plot point overflow in the case of the divider.The design of the divider fluid flow into equal parts shown in Fig. 1 and 2.The divisor of fluid flow into equal parts includes a housing 1, the supply line 2 for supplying a gas-liquid flow, the outlet pipe in the form of nozzles 3, patruno the diameter, the large diameter of the inlet pipe 2. In the casing of the window (Fig. 2, view A), they performed the same rectangular cross-section on the side of the case. In addition, they performed on the same height. While the outlet pipe, made in the form of nozzles 3, attached to the body inclined. The device is generally configured to provide flow of fluid flow in pipes through the Windows of rectangular cross-section. This permits the support pillars of the liquid in each of the nozzles below the level of the overflow of fluid from the body.In Fig. 1 shows only two of the pipe to drain parts of the fluid flow, there can be three, four, etc. as needed for the division of the stream by the number of parts.Gas-liquid mixture (production wells - oil, gas, water) flows through the inlet pipe 2 into the housing 1 of the divider. Because the diameter of the housing 1 (vertical cylinder) is greater than the diameter of the inlet pipe 2, the flow velocity in the body decreases, separates the free gas from the liquid and free gas flows through the exhaust pipe 5, occupies the upper part of the body of the divider and goes to the pipe 4. The incoming fluid (nm lateral pipes of the hydraulic resistance is different, in the descending branches are different levels of the liquid column. The greater hydraulic resistance, the higher the level of the liquid column. For normal operation of the divider of fluid flow into equal parts the level of the liquid column in any pipe must not rise to the level of overflow liquid from the housing that is provided by the corresponding hydraulic calculation and placement of the divider to the desired height.The gas space of the body of the divider through the pipe 4 is connected with the gas space of the subsequent devices that connect to the outlet pipe of the parts of the fluid flow, piping the gas spaces of the divider and apparatus serve to divert gas released in the body of the divider and alignment of the excess pressure in the divider and connected devices.The division of the flow of fluid into equal parts with the outlet of the nozzles is provided by the placement of Windows is equal to the cross section for filling at the same level in height vertically installed corps.the proposed divider fluid flow into equal parts works without the use of additional funds management process, easy to manufacture and Ratov one size, who will work with uniform loading. This eliminates the need to create and use large machines, you will be able to work with minimum reserve apparatus, increases the reliability and efficiency of the process.When the division of the stream into equal parts with the required accuracy and ensure the control and the adjustment of the vertical position of the body of the divider in use, the divider allows you to measure the expenditure of large compact measurement setup by measuring the consumption of only one part after dividing the stream into equal parts. The divisor of fluid flow into equal parts containing lead pipe, casing, the outlet pipe, characterized in that it is provided with a gas outlet pipe, placed in the enclosure, which is made in the form of a vertical cylinder with a diameter larger than a diameter of the inlet pipe, and the Windows of identical rectangular cross-section on the side, made at the same height as the outlet pipe is made in the form of nozzles attached to the body inclined, the device is configured to obese each of the nozzles below the level of the overflow liquid from the housing.
