Description

Technical Field

[0001] This utility model is a mass flow meter, belonging to the field of mass flow meters. Background Technology

[0002] A mass flow meter is an instrument used to measure the mass flow rate of a fluid (i.e., the mass of fluid passing through per unit time). It is widely used in industries such as chemical, petroleum, food, and power. It can provide high-precision and reliable flow measurement. Different mass flow meters are installed on different flow channels of a flow divider to measure various mass data of the fluid. The flow divider can also reduce the pressure loss caused by the flow meter itself, thereby improving the overall efficiency of the system. The flow divider can also prevent suspended particles or other substances that may damage the flow meter from entering the measuring part.

[0003] Existing mass flow meter distribution pipes are typically tee-shaped, with fluid entering at the top and exiting at the two bottom ends. However, there are connection nodes at the three internal channels of the tee. To prevent the fluid from impacting the branch pipe nodes, a flow divider is installed above the node inside the pipe. This divides the main pipe evenly before the fluid flows into the two branch pipes along both sides of the divider. Since the three ports of the distribution pipe have the same diameter, but the volume of the fluid after the division is reduced, the flow velocity at the two points after the division decreases. The fluid velocity is too slow, which can cause fluid stratification, making the measurement data of the mass flow meter inaccurate and reducing the measurement accuracy of the mass flow meter.

[0004] In summary, this utility model provides a mass flow meter to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mass flow meter to solve the problem of reduced measurement accuracy of the mass flow meter caused by the reduced flow velocity after flow splitting, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a mass flow meter, comprising a main pipe and two flow meters, wherein two connecting sleeves are fixedly connected to the bottom of each main pipe, the opposite sides of the two connecting sleeves are in contact with each other, a flow divider is fixedly connected between the two sides of the top contact of the two connecting sleeves and the inner wall of the main pipe, the bottom ends of the two connecting sleeves are connected to a flow guide bucket, the bottom ends of the two flow guide buckets are connected to a branch pipe, and the two flow meters are respectively installed on the two branch pipes.

[0007] Furthermore, the two connecting sleeves are uniformly semi-circular on the opposite side, and both sides of the main body are semi-circular.

[0008] Furthermore, the two sides of the main tube are flush with the sides of the two connecting sleeves, and the two connecting sleeves are fixedly connected.

[0009] Furthermore, the front sides of both connecting sleeves are flush with the front sides of the main body, and the back sides of both connecting sleeves are flush with the back sides of the main body.

[0010] Furthermore, both of the connecting sleeves are connected to the main body, and the top of the main cross-section of the diversion baffle is pointed.

[0011] Furthermore, the diversion baffle is fixedly connected to the main body, and the bottom inner diameter of the diversion bucket is smaller than the top inner diameter.

[0012] Furthermore, both branch pipes are bent at right angles, and the bends of the two branch pipes are curved.

[0013] The beneficial effects of this utility model are:

[0014] The fluid after diversion is delivered to two separate locations via two diversion buckets. Since the bottom diameter of the diversion bucket is smaller than the top diameter, and the top diameter of the diversion bucket is equal to the bottom diameter of the connecting pipe sleeve, and the bottom diameter of the diversion bucket is equal to the inner diameter of the branch pipe, the fluid delivery pipeline after diversion gradually narrows, the fluid passage path is reduced, thereby increasing the flow velocity and stabilizing the flow velocity after diversion, preventing the inaccuracy of the mass flow meter.

[0015] The fluid inside the main pipe is separated by a flow divider. The top of the main cross-section of the flow divider is pointed. The pointed top of the flow divider can increase the shear force of the flow divider on the fluid inside the main pipe, reduce the resistance of the flow divider on the fluid inside the main pipe, and improve the smoothness of the fluid diversion inside the mass flow meter.

[0016] Both branch pipes are bent at right angles, and the bends of the two branch pipes are curved. This reduces the impact on the bends of the branch pipes during the downward flow of fluid inside the branch pipes, thereby effectively reducing the overall resonance amplitude and frequency of the mass flow meter.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a mass flow meter, including a main body 1 and two flow meters 2. Two connecting sleeves 3 are fixedly connected to the bottom of each main body 1, with opposite sides of the two connecting sleeves 3 touching each other. A flow divider 4 is fixedly connected between the top touching points of the two connecting sleeves 3 and the two sides of the inner wall of the main body 1. A flow guide hopper 5 is connected to the bottom end of each of the two connecting sleeves 3, and a branch pipe 6 is connected to the bottom end of each of the two flow guide hoppers 5. Both flow meters 2 are connected to an external power supply and are equipped with a power control switch. The detection rods inside each flow meter 2 are located inside the branch pipes 6, allowing for the detection of the fluid transported inside the branch pipes 6. The two flow meters 2 are respectively installed on the two branch pipes 6. The opposite sides of the two connecting sleeves 3 are uniformly semi-circular arcs, and both sides of the main body 1 are semi-circular arcs. The wall thickness of the main body 1, branch pipes 6, flow guide hoppers 5, and branch pipes 6 is equal. This design ensures the fluid transport pipe is smooth. The top of the main pipe 1 is used for fluid input, and the ends of the two branch pipes 6 are used for fluid output. The two sides of the main pipe 1 are flush with the sides of the two connecting sleeves 3. The two connecting sleeves 3 are fixedly connected, with the front and back sides of the main pipe 1 flush with the front and back sides of the main pipe 1. The bottom port diameter of the diversion bucket 5 is smaller than the top port diameter, while the top port diameter is equal to the bottom port diameter of the connecting sleeve 3. The bottom port diameter of the diversion bucket 5 is equal to the inner diameter of the branch pipe 6. This design allows the fluid transport pipe to gradually narrow after diversion, reducing the fluid path and increasing the fluid velocity. This ensures a stable fluid velocity after diversion and prevents the mass flow meter 2 from becoming inaccurate. The two branch pipes 6 bend in opposite directions, forming left-right bends.

[0025] Please see Figure 2-4Both connecting sleeves 3 are connected to the main body 1. The top of the main section of the diversion baffle 4 is pointed. The pointed top of the diversion baffle 4 can increase the shear force of the diversion baffle 4 on the fluid inside the main body 1, reduce the resistance caused by the diversion baffle 4 on the fluid inside the main body 1, and improve the smoothness of fluid diversion. The diversion baffle 4 is fixedly connected to the main body 1. The bottom inner diameter of the diversion bucket 5 is smaller than the top inner diameter. Both branch pipes 6 are right-angle bends, and the bends of the two branch pipes 6 are arc-shaped. This reduces the impact on the bends of the branch pipes 6 during the process of the fluid impacting from top to bottom inside the branch pipes 6, thereby effectively reducing the overall resonance amplitude and frequency of the mass flow meter 2.

[0026] Detailed implementation: The top of the main pipe 1 is used for fluid input, and the two branch pipes 6 are both used for fluid output at their separated ends. During the process of conveying fluid from top to bottom through the top of the main pipe 1, the fluid is separated by the diversion baffle 4. The top of the main cross section of the diversion baffle 4 is angular. The angular top of the diversion baffle 4 can increase the shear force of the diversion baffle 4 on the fluid inside the main pipe 1, reduce the resistance caused by the diversion baffle 4 on the fluid inside the main pipe 1, and improve the smoothness of fluid diversion.

[0027] The two separated fluids are respectively transported to the interior of two connecting sleeves 3, and then sequentially transported from the connecting sleeves 3 to the diversion bucket 5 and the branch pipe 6. The detection rods inside the two flow meters 2 are located inside the branch pipe 6, which can detect the quality of the fluid transported inside the branch pipe 6. The two sides of the main body 1 are flush with the sides of the two connecting sleeves 3 respectively. The two connecting sleeves 3 are fixedly connected. The front of the two connecting sleeves 3 is flush with the front of the main body 1, and the back of the two connecting sleeves 3 is flush with the back of the main body 1. The wall thickness of the main body 1, the branch pipe 6, the diversion bucket 5, and the branch pipe 6 is equal, so that the pipeline for transporting fluid is smooth.

[0028] Because the bottom port diameter of the diversion bucket 5 is smaller than the top port diameter of the diversion bucket 5, the top port diameter of the diversion bucket 5 is equal to the bottom port diameter of the connecting pipe sleeve 3, and the bottom port diameter of the diversion bucket 5 is equal to the inner pipe diameter of the branch pipe 6, the fluid conveying pipeline after diversion gradually narrows, the fluid passage path narrows, thereby increasing the flow velocity and stabilizing the flow velocity after diversion, preventing the inaccuracy of the mass flow meter 2.

[0029] Both branch pipes 6 are bent at right angles, and the bends of the two branch pipes 6 are curved. This reduces the impact on the bends of the branch pipes 6 during the downward flow of fluid inside the branch pipes 6, thereby effectively reducing the overall resonance amplitude and frequency of the mass flow meter 2.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
