本発明は、密封性を保証しなくても流体の遮断を維持でき、流体遮断の高さを自動的に調整できる流体遮断装置を開示し、従来の技術における流体遮断装置が流体を遮断する時に、流体遮断の密封性を保証しなければ無効になってしまう欠点、及び流体遮断装置と同じ高さの流体しか遮断できない欠点を克服した。流体遮断装置は、高液面端と、低液面端と、を含み、前記高液面端と低液面端の間はパイプによって連通され、前記パイプは順次上下に起伏し、且つそれぞれの起伏は下端が隔てられ、上端が連通されるチャンバを形成し、前記チャンバ内に前部液柱、後部液柱、及び前部液柱と後部液柱を隔ててチャンバ上方に位置するエアシール部が設けられ、前記前部液柱の高さは後部液柱の高さより高い。本発明は従来の流体遮断装置が適用する場面に適用でき、従来技術において流体遮断時に密封性を保証しなければならない問題を回避し、高さを調整できるなどのメリットを有する。

    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.
