The water receiving frame 17 comprises a base 18, a support rod 19 connected to the base 18 and a water receiving plate 20 connected to the support rod 19, the cross section of the water receiving plate 20 is U-shaped, and the water receiving plate 20 is obliquely arranged.

The upper part of the measuring cylinder 12 is provided with an overflow pipe 13. The overflow pipe 13 is used to prevent the water level in the measuring cylinder 12 from rising rapidly due to an excessive flow rate, so that excessive water can flow out of the overflow pipe 13.

The side surface of the operating platform 1 is connected with a buffer frame 16, the water pump 3 is arranged on the upper part of the buffer frame 16, and the buffer frame 16 can reduce the vibration and noise of the water pump 3 during operation.

The lower part of the water outlet pipe 21 is provided with a concave table 24, the lower part of the test connector 22 is provided with an outer edge 23, the upper end surface of the outer edge 23 is attached to the upper end surface of the concave table 24, a sealing groove 25 is formed in the position, above the outer edge 23, of the water outlet pipe 21, a sealing ring 26 is arranged in the sealing groove 25, and the sealing ring 26 can prevent water from flowing out from a gap between the test connector 22 and the water outlet pipe 21 so as to ensure the accuracy of.

In specific implementation, in an initial state, the test connector 22 to be tested is inserted into the water outlet pipe 21 and fixed. The first regulating valve 9 and the second regulating valve 10 are fully opened, the water outlet ends of the water inlet pipe 7 and the water distribution pipe 8 are both positioned above the water tank 2, the water pump 3 is started, water in the water tank 2 is pumped in through the water pumping pipe 4 and then discharged through the water supply pipe 5, and the water is respectively sent into the water inlet pipe 7 and the water distribution pipe 8 through the three-way joint 6 and then flows into the water tank 2. The flow in the water inlet pipe 7 is reduced to a certain value by adjusting the first adjusting valve 9 and the second adjusting valve 10, and then the water outlet end of the water inlet pipe 7 is placed in the measuring cylinder 12, and water is supplied to the measuring cylinder 12 through the water inlet pipe 7. The water in the measuring cylinder 12 flows out through the hole in the test connector 22, passes through the through hole 27 on the table surface of the operation table 1 and falls into the water tank 2. After a period of time, the liquid level in the measuring tank 12 is observed, and if the liquid level in the measuring tank 12 cannot be kept stable, the aperture of the testing joint 22 is not matched with the flow in the water inlet pipe 7 at the moment, and the testing joint needs to be replaced. If the liquid level in the measuring cylinder 12 is kept constant after reaching a certain height, the aperture in the test joint 22 is adapted to the flow in the water inlet pipe 7 at that time. At this time, the water receiving rack 17 is moved to a position below the test socket 22, and the water flowing out of the test socket 22 flows into the measuring cup 14 along the water receiving plate 20. The height of the liquid level of the measuring cup 14 can be accurately measured through the liquid level transmitter 15, the change of the height of the liquid level of the measuring cup 14 in a period of time is measured, the flow can be calculated through a volume/time formula, and therefore the flow passing through the inner hole of the test connector 22 is obtained. When the liquid level in the measuring cylinder 12 is kept at a certain height, the flow rate in the water inlet pipe 7 is the same as the flow rate in the measuring joint 22, so that the flow rate in the water inlet pipe 7 can be obtained. Through this device, can test out the relative relation of flow in inlet tube 7, the interior liquid level height of test graduated flask 12, test joint 22 internal aperture.
