[0011] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0012] As Figure 1 shown, an equivalent shunt structure for dual-channel fluid flow distribution includes a fluid inlet pipe 1, a fluid outlet pipe 2, and two fluid branch pipes 3. A gas-liquid mixing rectifier is provided inside the fluid inlet pipe 1. The fluid inlet pipe 1 is connected to the two fluid branch pipes 3 through an equivalent four-way joint 4. A blind plug 5 is provided on one of the interfaces of the equivalent four-way joint 4. The fluid outlet pipe 2 is connected to the two fluid branch pipes 3 through a three-way joint 6. A main flowmeter 7 is provided on one of the fluid branch pipes 3, and a parallel pipe flowmeter 8 is provided on the other fluid branch pipe 3.
[0013] In this embodiment, the inner diameters of the two fluid branch pipes 3 are the same or the inner diameter of one of the fluid branch pipes 3 is several times that of the other fluid branch pipe 3.
[0014] In this embodiment, both the equivalent four-way joint 4 and the three-way joint 6 are connected to the two fluid branch pipes 3 through equivalent elbows 9.
[0015] In this embodiment, a valve 10 is provided between the parallel pipe flowmeter 8 and the equivalent elbow 9.
[0016] When this structure works, the fluid enters from the fluid inlet pipe 1 and then enters the equivalent four-way joint 4. The equivalent four-way joint 4 is located at the entrance of the structure and serves as the main channel bifurcation point. It has four interfaces. One interface is connected to the fluid inlet pipe 1, and two interfaces are respectively connected to the two fluid branch pipes 3 to ensure that the fluid can enter the two fluid branch pipes 3 evenly from the fluid inlet pipe 1. A blind plug 5 is installed on the other interface of the equivalent four-way joint 4 to close this interface, prevent fluid leakage, and maintain pressure balance at the same time. The equivalent four-way joint 4 is connected to the two fluid branch pipes 3 through equivalent elbows 9 to ensure smooth fluid turning, reduce flow resistance, and reduce energy loss.
[0017] A main flowmeter 7 is provided on one of the fluid branch pipes 3 to accurately measure the fluid flow passing through this fluid branch pipe 3 in real time and provide data support. A valve 10 and a parallel pipe flowmeter 8 with a similar internal structure to the main flowmeter 7 are installed on the other fluid branch pipe 3 to measure the flow of this fluid branch pipe 3, and its value is equivalent to the flow measured by the main flowmeter 7.
[0018] The valve 10 is combined with the parallel pipe flowmeter 8. By opening the valve 10, the measurement range of this structure can be increased; when the valve 10 is opened, the flow rate of this structure is: the flow rate measured by the main flowmeter 7 * calibration coefficient K; where K is the calibration coefficient.
[0019] At the ends of the two fluid branch pipes 3, equivalent elbows 9 are also used to guide the fluid to flow back, and a tee joint 6 is used to merge the two fluids and direct them to the fluid outlet pipe 2, ensuring smooth fluid outflow and avoiding the flow pattern caused by the merger.
[0020] The above-described embodiments only represent the specific implementation manners of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
