Embodiment Construction

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0024] Such as Figure 1 to Figure 2 As shown, a device for measuring the flow coefficient of a Venturi flowmeter includes a timer, a water storage tank 1, a water supply mechanism 2 connected to both ends of the water storage tank 1 and a measurement return mechanism 3, and a water supply mechanism 2 connected to the measurement return mechanism 3. Between the diversion mechanism 4. The timer adopts a stopwatch for recording the time of receiving water. The water storage tank 1 is the source of the experimental water body, and the water storage tank 1, the water supply mechanism 2, the diversion mechanism 4 and the measurement return mechanism 3 form a self-circulating water flow system, and the experimental water...

Abstract

The invention discloses a device for measuring the flow coefficient of a Venturi flowmeter, which comprises a timer, a water storage tank, a water supply mechanism connected to both ends of the water storage tank and a measuring backflow mechanism, and a device connected between the water supply mechanism and the measuring backflow mechanism. Diversion mechanism; it has good measurement effect and high accuracy. During the whole process of the experiment, the water body can be recycled and used, which can effectively save water resources and reduce water consumption; improve the utilization rate of water body and have good performance.

Description

technical field [0001] The invention relates to the technical field of fluid mechanics, in particular to a device for measuring the flow coefficient of a Venturi flowmeter. Background technique [0002] Because the laws of motion of liquid flow are very complex, all practical problems cannot be completely solved by theoretical research methods. Many unknown fluid motion laws still need to be explored and discovered through experimental research; the equipment used in the existing Venturi experiment is inconvenient to operate, the measurement effect is poor, the accuracy of the measurement results is low, and it is only suitable for the measurement of small flow rates. low performance. Contents of the invention [0003] The object of the present invention is to provide a device for measuring the flow coefficient of a Venturi flowmeter to solve the problems of poor measuring effect and low performance of existing measuring equipment. [0004] The technical scheme of the pr...
