[explanation of connecting means]
Next, the method that flexible pipe 300 is connected to above-mentioned flexible Pipe joint 10 is described.
At first, the operator removes the coating 314 corresponding with several protuberances 310 from the front end of flexible pipe 300.If coating 314 remove end, the operator makes flexible pipe 300 pass pressure ring 26.The front end of flexible pipe 300 is outstanding from the annulus 60 of pressure ring 26.
Then, the operator opens the separated part 110 of the fixing part 86 of guard ring 24.When separated part 110 opened, the operator made the claw 92 of guard ring 24 be embedded into recess 312 places of the front end of flexible pipe 300.When the claw 92 of guard ring 24 was embedded into recess 312 place of flexible pipe 300, the cylinder section 100 of fixing part 86 naturally and understandably covered the annulus 60 of pressure ring 26.Like this, guard ring 24 is installed on flexible pipe 300.At this moment, the front end of flexible pipe 300 is also outstanding from the claw 92 of guard ring 24.
Then, the operator is embedded in the front end gasket groove 52 of adapter body 20 front end packing ring 22.When front end packing ring 22 was embedded into, the operator made flexible pipe 300 be inserted into the access path 36 of adapter body 20 together with guard ring 24 and pressure ring 26.When the outside thread 62 of pressure ring 26 is inserted into the access path 36 of adapter body 20, internal thread 48 interlocks of its outside thread 62 and adapter body 20.When operator under this state rotated pressure ring 26 and adapter body 20 one another in opposite directions, guard ring 24 moved towards the depths of the access path 36 of adapter body 20.Do like this is in order to make the annulus 60 of guard ring 24 extruding pressure rings 26.Because the internal diameter of the taper hole 50 of access path 36 is adjacent to section 38 and diminishes along with approaching, therefore, along with guard ring 24 moves towards access path 36 depths, the outer circumferential face of the cylinder section 100 of guard ring 24 is compressed by the inner peripheral surface of taper hole 50.Simultaneously, from the fore-end of the outstanding flexible pipe 300 of guard ring 24 at the claw 92 of guard ring 24 be adjacent between section 38 and be extruded and plastic deformation.Even the fore-end plastic deformation of flexible pipe 300, can prevent that also its part from hindering the flowing of inside of flexible pipe 300.This is because protuberance 40 is outstanding.
[according to the effect of the flexible Pipe joint of present embodiment]
Can obviously find out from above explanation, according to a plurality of abjunction preventing parts 84 of present embodiment, be fixed on fixing part 86., because abjunction preventing part 84 is fixed, when guard ring 24 is connected to the flexible pipe 300 that is located at narrow place,, if keep the somewhere of guard ring 24, will reduce the possibility that the part of a plurality of abjunction preventing parts 84 falls.Possibility because the part that can reduce a plurality of abjunction preventing parts 84 falls, therefore, can prevent the connection cost time to the flexible pipe 300 of being located at narrow place thus.Consequently, can provide a kind of guard ring 24 that can easily to the flexible pipe 300 of being located at narrow place, connect.
And, according to a position of position of the cylinder section 100 of present embodiment and the clamping part 102 relative with it, separate from the end to end of axis 250 directions respectively.Thus, apply power at this position and under the state opened, guard ring 24 be embedded on flexible pipe 300, when guard ring 24 is embedded on flexible pipe 300, just can at this position, not applying power.When being embedded into guard ring 24 on flexible pipe 300 as described above, to compare with the situation of the same resiliently deformable in cylinder section 100 and clamping part 102 generations and abjunction preventing part 84, the operation that guard ring 24 is embedded on flexible pipe 300 becomes easy.
And the end to end from axis 250 directions of clamping part 102 separates clamping part 102 at a plurality of positions.Thus, with 102 situations of at a position, separating of clamping part, compare a position of the separation of easily opening a section 100 of becoming.While when becoming, easily opening this position, with the situation that is not easy to open this position, compare, the operation that guard ring 24 is embedded on flexible pipe 300 becomes easy.
And if the mode that with annulus 60 tube sections 100, does not cover is contained in adapter body 20 guard ring 24, the fore-end of flexible pipe 300 just can not be adjacent in section 38.This is owing to being hindered pressure rings 26 to enter than the position of depths more of the assigned position in adapter body 20 by guard ring 24.Thus, can prevent with annulus 60 not the mode that covers of tube section 100 guard ring 24 is contained in adapter body 20.
By making protuberance 40 outstanding, can prevent after the moulding distortion of the fore-end of flexible pipe 300, its part hinders the flowing of inside of flexible pipe 300.
