The invention discloses a negative-pressure-type dredging device for blocking a pipeline. The negative-pressure-type dredging device includes a body shell. The independently formed negative pressure is used, so that the negative pressure can be combined with the atmospheric pressure in the sewer pipeline so as to enable a negative pressure state to be formed in the sewer pipeline, an internal blocked part is dredged under the negative pressure state, due to the negative pressure is stressed inwards, and the resistance of the inward stress of the pipeline is large, so that the damage to the pipeline is low; moreover, the negative-pressure-type dredging device is provided with a coil spring elastic compression resistance-type maximum air difference control mechanism, so that the occurrence of pipeline rupture caused by excessive negative pressure is prevented; in addition, the negative-pressure-type dredging device is provided with a tapered pipeline connection blocking sealing mechanismwhich can be pressed on a sewer pipeline port to prevent outside air from entering; and in addition, the negative-pressure-type dredging device is provided with an annular array coil spring type maximum rotation resistance control mechanism, and the maximum value of the internal negative pressure can be controlled, so that the damage of parts caused by the large degree of air extraction is avoided.
本发明公开了一种堵塞管道用负压式疏通装置，包括主体壳体。本发明利用独立形成的负压，使得该负压能够与下水管道中的大气压相结合，使得下水管道内部形成负压状态，在负压状态下对内部的堵塞部位进行疏通，由于负压受力向内，而管道向内受力抗性大，所以对管道损伤程度低，而且，该装置具有螺旋弹簧弹性压缩抵触式最大空气差控制机构，防止负压过大而导致的管道破裂现象的发生，此外，该装置具有锥形管道连接堵塞密封机构，能够按压在下水管道口，防止外界空气进入，另外，该装置具有环形阵列螺旋弹簧式最大旋转阻力控制机构，能够控制内部负压的最大值，防止抽气程度大导致的部件受损现象的发生。
