Description

Technical Field

[0001] The utility model belongs to the technical field of flow meters, and in particular relates to a flow meter for water balance testing. Background Art

[0002] A flow meter is an instrument that measures the flow rate and / or the total amount of fluid in a selected time interval. It is an instrument used to measure the flow rate of fluid in a pipeline or open channel. Flow meters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, and ultrasonic flow meters. Flow meters are divided into liquid flow meters and gas flow meters according to the medium. Flow meters can be divided into instantaneous flow and cumulative flow in engineering. Instantaneous flow refers to the amount of fluid flowing through the effective cross-section of a closed pipeline or open channel per unit time. The substance flowing through can be gas, liquid, or solid; cumulative flow refers to the cumulative amount of fluid flowing through the effective cross-section of a closed pipeline or open channel within a certain time interval.

[0003] In the process of implementing the utility model, the inventors found that there are at least the following problems in the technology: the existing flow meter, such as the patent with application number CN202123376905.3 - a portable flow meter for water balance test, can usually only test the flow rate when the pipeline is fully open. In actual use, the pipeline may not be fully open, but partially closed, which leads to the test results cannot fully meet the needs of actual use.

[0004] Therefore, we propose a flow meter for water balance test to solve the above problems. Utility Model Content

[0008] As a preferred embodiment, connecting seats are welded on the outer walls on both sides of the pipeline, and base plates are welded under the two connecting seats; the two connecting seats are symmetrical to the two sides of the pipeline, and the design of the base plate and the two connecting seats can ensure that the pipeline and all structures thereon maintain structural stability.

[0009] As a preferred implementation scheme, a protruding seat is fixedly welded on the top wall of the positioning seat, wherein the interior of the protruding seat is a hollow design, and the servo motor is installed on the bottom wall of the inner cavity of the protruding seat; so that the structure of the servo motor remains stable, and the servo motor requires external power facilities for power supply.

[0010] As a preferred implementation scheme, heat conducting sheets are attached to both sides of the outer wall of the servo motor, and the two heat conducting sheets are C-shaped and surround the outside of the servo motor, and metal heat conducting plates are attached to the outside of the two heat conducting sheets, and the metal heat conducting plates are welded integrally with the protruding seat; thereby, the heat released by the servo motor can be conducted out through the attachment of the heat conducting sheets to the servo motor, and then quickly conducted out to the outside through the metal heat conducting plates, so that the servo motor can achieve good heat dissipation and ensure its stability under continuous working conditions.

[0011] As a preferred embodiment, the screw is vertically arranged in the bottom groove, and the screw is rotatably connected to the positioning seat, so that the screw can operate stably under the drive of the servo motor.

[0014] If the flow meter for horizontal balance test needs to test the flow rate under different conditions of the amount of fluid input per unit time, the servo motor is operated to drive the screw to operate, so that the closing disk, extension rod and flow regulating plate are raised and lowered along with the inner wall of the bottom trough, so that the flow regulating plate closes the opening on one side of the pipeline to a certain extent, thereby testing the flow value under different conditions, meeting the testing and use requirements in more scenarios.
