Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flow detection, in particular to a synchronous distribution device. Background Art
[0002] In the aviation field, many multi-channel parts need to be tested for flow to ensure that their performance is qualified. When controlling the flow of measuring components, the existing test equipment directly connects each channel of the component to the measuring mechanism through a hose, and measures the flow of the component channel by the volumetric method (measuring the volume of the measuring cylinder per unit time). Through manual or electric valves, the flow of the fluid at the inlet of the component is cut off, and the distribution of the fluid is cut off from the source, so as to achieve the purpose of opening and closing each channel at the same time. The general experimental process is: open the inlet valve of the component; timing; close the inlet valve of the component after the timing is completed; count the volume of the fluid in each measuring mechanism and calculate the flow.
[0003] However, the above equipment uses valve opening and closing as the start of timing when distributing fluid. However, after the valve is opened, it takes several seconds to send the fluid into the designated measuring mechanism. After the valve is closed, the fluid in the pipeline will still flow into the measuring mechanism uncontrollably, resulting in deviations in the measurement results. In addition, there is no effective synchronization restriction for fluid distribution, and the length of the pipeline is often inconsistent due to the size of the equipment, resulting in measurement deviations. In order to facilitate the test, most equipment is open, and the fluid is easily contaminated by the outside world. Utility Model Content
