The utility model principle of work is:
Pressure testing is prepared: earlier plug 7 is penetrated steel pipe 12, turn nut 8 and drive orienting sleeve 9, conical surface pressing plate 10 compresses sealing 11, connects the last quick change 6,14 on the hydraulic means then, can realize work.
Water-filling: start charging pump 16, low-pressure water enters along 14,13 flow-guiding channels by plug 7 in the annular seal space of steel pipe 12 and plug 7, and the gas in the annular seal space is discharged by flow-guiding channel, the quick change on the hydraulic means 6, the vent valve 5 of the plug other end.When treating that vent valve 5 draw-offs do not have air, close charging pump 16, close vent valve 5, water-filling is finished.
Pressure testing: start high pressure testing pump 2, by quick change 6, another flow-guiding channel of plug 7 enters annular seal space to water under high pressure, when treating that tensimeter 4 reaches specified pressure 20Mpa, closes high pressure testing pump 2 along the retaining valve on the hydraulic means 3.
Release: open vent valve 5 releases.
Finish pressure testing: open quick change 6,14, turn on nut 8, take out plug 7, pressure testing is finished.
