Whether the liquid levels of the inner ring and the outer ring are consistent is the key point of the success of the whole test, if the liquid levels of the inner ring and the outer ring cannot be consistent, if the liquid level of the inner ring is higher than the liquid level of the outer ring, part of water of the inner ring participates in the permeation process of the outer ring, so that the test result is bigger; if the liquid level of the inner ring is lower than that of the outer ring, part of water of the outer ring can permeate to the inner ring, so that the test result is smaller. The traditional testing device is not provided with drain valves on the inner ring and the outer ring, so when the traditional testing device is adopted for testing, water is firstly injected into the inner ring and the outer ring respectively, and the water level heights of the inner ring and the outer ring are required to be adjusted to be consistent by repeatedly measuring the water level in the inner ring and the outer ring and controlling the water injection of the Margaret bottle; and the structure of the Marshall bottle used for keeping the water level of the inner ring and the water level of the outer ring is unreasonable, the length of a single air inlet pipe of the Marshall bottle mouth is not easy to adjust, and the water level height of the inner ring and the water level height of the outer ring are difficult to control and adjust. Therefore, a device for rapidly and consistently maintaining the liquid level in the inner ring and the outer ring after water injection and maintaining long-term stability is needed.
