Description

Technical Field

[0001] This utility model belongs to the field of flow meter technology, specifically relating to a pump tube flow meter. Background Technology

[0002] In industrial sectors such as petrochemicals and power energy, continuous and stable flow monitoring of fluids is required. Pump-pipe flow meters, due to their numerous advantages, are widely used in medium- and high-pressure transmission systems and high-purity media measurement scenarios. In municipal water services, with the increasing demand for leakage control in urban water supply networks and the advancement of smart network construction, the reliance on accurate metering equipment is constantly increasing, making pump-pipe flow meters an important flow measurement tool.

[0003] Traditional products lack a cleaning design. When the detection head is contaminated by impurities in the fluid and needs to be cleaned or replaced, the entire flow meter must be removed from the pipeline, making in-situ maintenance impossible. At the same time, most products do not have a specific impurity protection structure, and solid particles in the fluid can easily directly impact the detection components, which not only shortens the service life of the detection head but also requires frequent shutdowns for maintenance, increasing operation and maintenance costs and equipment.

[0021] Furthermore, the valve body 105 is fixed in the middle section of the pipe 101, and a sliding groove 110 is provided inside. The valve cover 106 is fixed to the top with screws. The valve 107 slides in the sliding groove 110 to control the water flow. A limiting groove 112 is provided on the side wall of the valve 107. The valve stem 108 is threaded into the threaded sleeve provided on the side wall of the valve body 105, and its end extends into the inside of the valve body 105. The valve 107 is inserted from the top opening of the valve body 105. The limiting groove 112 is aligned with the limiting block at the end of the valve stem 108 and slides in. The valve stem 108 can be rotated to push and pull the valve 107 inside the valve body 105.

[0027] In use, workers tighten bolts to quickly connect flange 111 to external pipelines. As fluid flows through pipe 101, filter 207 intercepts impurities, and guide pipe 103 directly contacts the fluid to collect parameters, which are displayed in real-time by the flow meter body 104. Rotating handle 109 drives valve 107 to open and close inside valve body 105, controlling water flow for testing or maintenance. When impurities adhere to the surface of guide pipe 103, affecting detection accuracy, rotating handle 202 rotates guide rod 203, causing brush handle 205 and brush 206 to rotate around guide pipe 103, removing surface impurities through friction from the brush 206. Sealing disc 204 maintains a seal as guide rod 203 rotates, preventing fluid leakage.

[0028] In summary, the use of threaded or plug-in connections between parts facilitates individual disassembly and replacement, reducing maintenance costs. The brush 206, driven by the handle 202, cleans the guide tube 103 without the need for specialized tools. The filter screen 207 effectively intercepts debris, preventing impact on the guide tube 103, while the brush 206 promptly removes surface impurities, ensuring testing accuracy and extending the service life of the guide tube 103. The rotation of the handle 109 controls the water flow through the valve 107, facilitating equipment inspection and maintenance by personnel.
