摘要： PURPOSE: A liner tube repairing device using the negative pressure in the inversion insertion of a liner tube and a method thereof are provided to securely attach a superannuation conduit and the liner tube and prevent the liner tube from being crinkled. CONSTITUTION: A liner tube repairing device using the negative pressure in the inversion insertion of a liner tube comprises a gland(32), a temporary valve(34), a rubber ring(36), a vacuum unit and a sealing unit. The gland is installed in the outlet side end exterior of a superannuation conduit line which needs to be repaired. The temporary valve has a flange through the gland. The rubber rind is located between the grand and the flange of the temporary valve and maintains air-tightness. The vacuum unit is connected to the temporary valve and supplies the negative pressure to a revival section of the superannuation conduit. The sealing unit is mounted on an end of the liner tube in which the superannuation conduit is repaired and supplies the air-tightness to the superannuation conduit.
