[0002] In the petroleum, chemical and energy sectors, accurate metering of multiphase flow is a core element of production process optimization and cost control. Traditional multiphase flow meters typically adopt a single-channel fixed design, with pipeline connections relying on on-site welding or flange fixing, resulting in a complex and time-consuming installation process. Furthermore, maintenance requires complete disassembly, which can easily lead to leakage risks. In particular, maintenance costs are high in high-pressure and corrosive environments. In addition, this rigid structure lacks modular flexibility and cannot adapt to complex production scenarios with multiple wellheads and multiple operating conditions. It is also difficult to quickly adjust and match different fluid characteristics, affecting the versatility and adaptability of the device. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a combined multiphase flow metering device, which solves the problems of traditional multiphase flow meters that usually adopt a single-channel fixed design, whose pipeline connection relies on on-site welding or flange fixing, resulting in a complicated and time-consuming installation process, and requiring overall disassembly for maintenance. In addition, this rigid structure lacks modular flexibility, cannot adapt to complex production scenarios with multiple wellheads and multiple working conditions, and is difficult to quickly adjust to match different fluid characteristics, affecting the versatility and adaptability of the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined multiphase flow metering device, comprising a connecting pipe, wherein a plurality of liquid inlet pipes are uniformly and equidistantly fixedly connected to one side of the connecting pipe, a first valve is fixedly installed in the middle of the liquid inlet pipe, and a liquid inlet is provided at the end of the liquid inlet pipe.

[0009] As a further embodiment of this utility model: a sensor is fixedly installed on the outer wall of the liquid outlet pipe, and a second measuring instrument is fixedly connected above the sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This combined multiphase flow metering device, by setting up an inlet pipe, a first connecting plate, fixing bolts, and an inlet pipe, achieves a quick, convenient, and stable connection between the inlet pipe and the inlet pipe by using the first and second connecting plates in conjunction with the fixing bolts.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a combined multiphase flow metering device, including a connecting pipe 1, a plurality of liquid inlet pipes 2 are uniformly and equidistantly fixedly connected to one side of the connecting pipe 1, a first valve 3 is fixedly installed in the middle of the liquid inlet pipe 2, a liquid inlet 4 is opened at the end of the liquid inlet pipe 2, a first connecting piece 5 is fixedly connected to the outer wall of the liquid inlet pipe 2 near the liquid inlet 4, a delivery pipe 6 is provided on one side of the liquid inlet pipe 2, a second connecting piece 7 is fixedly connected to the outer wall of the end of the delivery pipe 6 opposite to the liquid inlet pipe 2, a plurality of fixing bolts 8 are threadedly connected to one side of the second connecting piece 7, and the delivery pipe 6 is connected to the liquid inlet pipe 2 through the first connecting piece 5, the second connecting piece 7 and the fixing bolts 8. This design allows the delivery pipe 6 to be quickly and conveniently connected to the liquid inlet pipe 2, and the fixing bolts 8 are used to achieve fastening, ensuring the stability and sealing of the connection. This modular connection method not only facilitates installation and maintenance, but also allows for flexible adjustment of the number and position of the delivery pipes 6 as needed, improving the adaptability and flexibility of the device.

[0020] An infusion port 9 is provided at the other end of the infusion tube 6. A metering module 10 is fixedly installed in the middle of the infusion tube 6. Metering blades 11 are rotatably connected between the inner walls of the metering module 10. Because of the metering blades 11, the metering blades 11 rotate inside the metering module 10 and directly contact the fluid. The flow rate of the fluid is accurately measured by its rotation speed and angle. This direct contact metering method can reduce metering errors and improve metering accuracy. The setting of the first flow meter 12 can record and display the flow data in real time, which is convenient for monitoring and analysis. The first flow meter 12 is fixedly installed on the top of the metering module 10. A second valve 13 is fixedly installed on the outer wall of the infusion tube 6. The second valve 13 is located outside the metering module 10. The first valve 3 and the second valve 13 control the flow of fluid in the inlet tube 2 and the infusion tube 6, respectively, so that the operator can accurately control the inflow and outflow of fluid as needed. This design helps to prevent fluid backflow and also facilitates the maintenance or replacement of individual pipes without stopping the entire system.

[0021] The connecting pipe 1 has a U-shaped design, which allows the multiphase fluids entering from multiple infusion pipes 6 to converge within the connecting pipe 1. This design helps to evenly distribute the fluid, reduce turbulence and pressure loss within the connecting pipe 1, thereby improving the accuracy of flow measurement and the overall efficiency of the device. On the other side of the connecting pipe 1, at its central position, an outlet pipe 14 is fixedly installed. A sensor 15 is fixedly installed on the outer wall of the outlet pipe 14. A second metering device 16 is fixedly connected above the sensor 15. The second metering device 16 can further monitor and record the physical properties of the fluid, such as temperature and pressure. This additional measurement function provides more data support for fluid analysis and helps to more comprehensively understand the properties and behavior of the fluid.

[0022] The working principle of this utility model is as follows: When using the device, align the second connecting piece 7 at one end of the infusion tube 6 with the first connecting piece 5 at one end of the inlet tube 2, fix the infusion tube 6 to one end of the inlet tube 2 with the fixing bolt 8, open the first valve 3 and the second valve 13, and input multiphase fluid from the infusion port 9. When the multiphase fluid flows in the infusion tube 6, it drives the metering blade 11 to rotate in the metering module 10. The metering blade 11 transmits the flow rate of the multiphase fluid to the first flow meter 12. The first flow meter 12 records and displays the flow rate data of the fluid. The multiphase fluid flows through the infusion tube 6 and into the connecting pipe 1 through the inlet port 4 and the inlet tube 2. The multiphase fluids entering from multiple infusion tubes 6 converge in the connecting pipe 1 and finally flow out from the outlet tube 14. The sensor 15 and the second metering device 16 above further monitor and record the physical properties of the fluid, providing additional measurement data for use of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
