The job step of the fluid pressure type pipe-expanding device 1 that uses present embodiment is below described.At this, expand tube liquid W1 is water.First, connect the power switch of main body 2.Then,, toward main body 2 air supplies, press and be ready to complete button.So, by the shown exhaust button of the touch-screen of main body 28, carry out the interior exhaust of booster 4.During exhaust, servomotor 48 work, plunger 45 moves back and forth, and from supply tank 6, sucks voluntarily expand tube liquid W1, and decompression draining 422 quilts by pressure maintenance valve 42 are discharged to supply tank 6 together with air.Then, at touch-screen 8, set expand tube pressure P 2.So, sealing 9 is assembled to the outlet side (in Fig. 4 left side) of expand tube tool portion 3, sealing 9 is inserted to the pipe 109 of heat exchangers etc.So, continue to press expand tube button 39 (referring to Fig. 4) on hand in expand tube tool portion 3, carry out expand tube operation.During expand tube operation, pressure maintenance valve 42 is supplied to air A1 and closes after valve, booster 4 work, super-pressure by pressure maintenance valve 42 spues 421, super-pressure expand tube liquid W2 is fed to expand tube tool portion 3, the tubulose liquid bag 107 of sealing 9 is supplied to super-pressure expand tube liquid W2, by the pressure P 2 of super-pressure, pipe 109 expand tubes.When reaching expand tube pressure P 2, maintain after 2 several seconds of this pressure P (1～3 second), the expand tube that sounds finishes prompt tone, and pressure maintenance valve 42 is opened and is reduced pressure.So, unclamp after expand tube button 39, from pipe 109, pull up sealing 9, be inserted into next pipe 109, continue to press expand tube button 39 on hand in expand tube tool portion 3, repeat expand tube operation.
It should be noted that, the utility model is not defined in above-mentioned embodiment, can change specification corresponding to various variations.For example, although what describe in above-mentioned embodiment is to maintain valve 42 by Pneumatic valve 5 controlled pressures, be not limited thereto, also can maintain valve 42 by electrically-controlled valve controlled pressure.Visible, the utility model can be done suitable change in the scope that does not depart from its design, and this need not superfluous words.
