Adaptive sealing devices for pipeline porous leakage

Abstract

The embodiments of the present disclosure provide an adaptive sealing device for pipeline porous leakage. The device includes a pressure protection device and an encircling sealing rubber cover. The pressure protection device is used to pressurize and seal the pipeline based on the encircling sealing rubber cover. The device further includes a control mechanism connected with the pressure protection device for adjusting the sealing pressure of the pressure protection device on the pipeline. The device further includes an anti-retraction mechanism connected with the pressure protection device and the control mechanism for limiting the pressure protection device and/or the control mechanism.
