The present invention discloses an intercepting device capable of maintaining interception without the need of ensuring the sealing performance and automatically adjusting a height for interception. This intercepting device overcomes the deficiencies that a prior art intercepting device will fail to work if failing to ensure the sealing performance and can block only fluid at a same height as the intercepting device. This intercepting device comprises a high liquid level end (1) and a low liquid level end (2), the high liquid level end being in communication with the low liquid level end via a conduit, the conduit being provided successively in a fluctuating manner and every fluctuation forming a chamber with its lower end separated and its upper end communicated; and within the chamber, provided are a front liquid column segment (3), a rear liquid column segment (4), and an air-sealed segment (5) located in the upper portion of the chamber to separate the front liquid column segment from the rear liquid column segment, the height of the front liquid column segment being greater than that of the rear liquid column segment. The intercepting device is applicable to the occasions where a conventional intercepting device is applicable, avoids the problem in the prior art of needing to ensure the sealing performance while intercepting, and is capable of adjusting the height for interception.
