Method and apparatus for pipe leakage repairing

This invention discloses a method of pipe leakage-repairing and quick repairing and its devices. This method include: (1) use holding block to hoop the leaking pipe, transfer the leaking medium to distant place through a pressure-discharging tube with valve gate; (2) bind the holding block and the pipeline tightly; (3) close the valve gate, cut off the pressure-discharging tube. This device is a new kind of holding block, including the blocking body and the pressure-discharging device. The pressure-discharging device consists of a hollow chamber protruding on the blocking body, a valve gate connected with the chamber and a pressure-discharging tube linked with the valve gate. This invention solves the problem of medium pressure, and can be applied on any pipes of oil chemistry and gas, and will not reduce the pressure of the medium in the pipe or stop the medium transmission.
