Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, specifically to three-way flow meters. Background Technology

[0002] Three-way flow meters are important devices in the field of flow measurement and are widely used in process industries such as chemical, petroleum, and natural gas, as well as in energy management and water conservancy projects. Traditional three-way flow meters mainly use the Venturi effect, differential pressure principle, or electromagnetic induction principle to divide the fluid and measure parameters such as pressure difference and flow velocity through the three-way structure, thereby calculating the flow rate.

[0003] Based on the above, the inventors have discovered the following problems: When existing flow meters are used for a long time under high flow conditions, the large flow rate in the fluid chamber will cause the impeller assembly to rotate too fast, affecting the service life of the impeller assembly. At the same time, it will reduce the pressure bearing capacity of the fluid chamber and affect the overall service life of the flow meter.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide equipment in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a three-way flow meter to solve the problems in the current background technology.

[0006] This utility model can achieve the purpose and function of a three-way flow meter, which is achieved by the following specific technical means:

[0007] The three-way flow meter includes a buffer mechanism body, which includes a measuring tube. One end of the measuring tube has a second outlet, and the inner side of the second outlet has a first front guide impeller. One side of the first front guide impeller has a first connecting shaft, and one end of the first connecting shaft has a first fixing member fixedly attached. The measuring tube is fixedly attached to the outer side of the first fixing member.

[0008] The beneficial effect of adopting the above-mentioned further solution is that when the water is sprayed out from the second outlet, the pressure of the spraying device body is reduced by the first front guide impeller, and the first fixing member provides a fixed connection between the first front guide impeller and the measuring tube.

[0009] Furthermore, one end of the measuring tube is provided with a first water outlet, the inner side of the first water outlet is provided with a third front guide impeller, one side of the third front guide impeller is provided with a third connecting shaft, one end of the third connecting shaft is provided with a third fixing member, and the measuring tube is fixed on the outer side of the third fixing member.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when the water is sprayed out from the first outlet, the pressure of the spraying device body is reduced by the second front guide impeller, and the second fixing member provides a fixed connection between the third front guide impeller and the measuring tube.

[0011] Furthermore, one end of the measuring tube is provided with a water inlet, the inner side of the water inlet is provided with a second front guide impeller, one side of the second front guide impeller is provided with a second connecting shaft, the outer side of the second connecting shaft is provided with a second fixing member, and one side of the second fixing member is provided with a rear guide impeller.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the water flow enters the device body from the inlet, the water pressure is weakened after passing through the second front guide impeller, and the pressure is further weakened after passing through the rear guide impeller. The second fixing member provides fixation between the second front guide impeller and the rear guide impeller and the measuring tube.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the anti-corrosion inner layer provides anti-corrosion effect for the inside of the measuring tube, reduces damage inside the measuring tube, and improves the service life of the measuring tube. When water flows into the measuring tube, the water pressure is weakened by the action of the guide thread, and some water and impurities will enter from the cleaning hole into the guide thread and then flow out from the first cleaning tube and the second cleaning tube.

[0020] Furthermore, a second cleaning tube is provided below one side of the flow guide thread.
