Pipe in above-mentioned flexible water pipe 200, comprises pipe 212 and an outer tube 214 in one.Wherein, interior pipe 212 has inflatable flexible elasticity.And outer tube 214 is a braided fabric, and be coated on interior pipe 212 outer surface, outer tube 214 only has the elasticity of axial stretching, and interior pipe 212 is identical with outer tube 214 length.
Above-mentioned interior pipe 212, comprises at least one osculum and at least one rib 216.Interior pipe 212 has water tightness and inflatable flexible elasticity, osculum then axially runs through and is formed at interior pipe 212, make interior pipe 212 expand flexible by the adjustment of source pressure in osculum internal diameter, in addition, rib 216 is formed at the inside diameter surface of interior pipe 212 osculum.When avoiding interior pipe 212 flexible by rib 216, internal diameter tangles and causes interior pipe 212 osculum internal diameter cross section to be caused closed (similar interior pipe doubling).During enforcement, osculum can take the enforcement pattern of single or most combination on demand.
Above-mentioned outer tube 214, has several elasticity warp thread 220 and several non-resilient weft yarn 222 braiding forms (as shown in Figure 3).Wherein, each elasticity warp thread 220 has ductility, and axially arranges along interior pipe 212, and each non-resilient weft yarn 222 does not then have ductility, arranges along interior pipe 212 radial direction.
Be with, above-mentioned be this create a preferred embodiment a kind of device comprising flexible water pipe and pipe joint of providing, the introduction of each portion component and assembling mode thereof, then again its handling characteristics is described as follows: first, refer to shown in Fig. 1 to Fig. 6, water pipe 200 will be stretched through after the second pipe fitting 180 and the first pipe fitting 160, one end is sheathed on the bell and spigot joint 121 (neck 126 and head 128) of tube body 120, it is made to hold as in flexible water pipe 200, clamping element 140 is linked at neck 126 (because flexible water pipe has elasticity and softness again, therefore flexible water pipe can be connected to neck 126 closely by clamping element 140), when the first pipe fitting 160 is threadedly connected to tube body 120, the outer tilted conical surface 144 of the first tilted conical surface 165 pairs of clamping elements 140 of the first pipe fitting 160 forms tapering packing, reach held tight, the interior tilted conical surface 142 of clamping element 140 is forced to form tapering packing with neck 126, middle flexible water pipe 200 first paragraph 202 is connected in clamping and forms fastening clamp (as shown in Figure 4), in addition, flexible water pipe 200 second segment 204 (as shown in Figure 4) is by the clamping of clamping element 140 with head 128 ear end face 127, and around folding multiple knuckle point (the flexible water pipe namely clamped between clamping element 140 and head 128 ear end face 127), by knuckle limit telescopic water pipe 200 second segment 204, form tapering packing by the tilted conical surface 129 of the second tilted conical surface 166 engagement head 128 outer surface of the first pipe fitting 160 again, middle the 3rd section 206, flexible water pipe 200 (as shown in Figure 4) is connected to clamping and forms held tight.
In addition, flexible water pipe 200, by the coated interior pipe 212 of outer tube 214, makes the external diameter of interior pipe 212 be equivalent to the internal diameter of outer tube 214.Therefore when interior pipe 212 does not connect water source (time in interior pipe 212 without pressure), in it, pipe 212 is identical with the length L of outer tube 214, the pipe thickness A the thickest (as shown in Figure 6,7) of pipe 212 now.
When interior pipe 212 connects water source, interior pipe 212 osculum aperture surface is shored (as Suo Shi Fig. 7 ~ 8) by source pressure, make interior pipe 212 prolonged expansion, but the constraint of limited outer tube 214 (the non-resilient weft yarn 22 forming outer tube 214 radial direction do not have ductility) therefore the length B close (as Fig. 6, Fig. 7) of outer tube 214 and interior pipe 212 radial direction.Also because interior pipe 212 radial direction is tied expansion, force interior pipe 212 to concentrate and extend (as Fig. 7 ~ 10) towards axial expansion, and during prolonged expansion outer tube 214 can be pulled in the lump and synchronizing shaft to extending the elasticity warp thread 20 of outer tube 214 (form there is elasticity), therefore interior pipe 212 is synchronous with outer length of tube L ' extends (as shown in Figure 7) and interior pipe 212 pipe thickness A ' after prolonged expansion only can slightly reduce, avoid identical above-mentioned known defect occurs, the excessively thin problem of breaking of interior pipe 212 tube wall is caused because of radial expansion, and the disappearance that axial elongation reduces.
And by the dilatancy of above-mentioned flexible water pipe 200, make the utility model remove said structure to reach and be fastenedly connected, outside the multiple constraints such as knuckle and packing clamping and anticreep, more pass through the expansion space 186 compared with large diameter between the necking part 184 of the second pipe fitting 180 and contiguous first pipe fitting 160, the space that flexible water pipe 200 1 expands is provided, therefore when flexible water pipe 200 connects water source and form hydraulic pressure in flexible water pipe 200, the tube wall of flexible water pipe 200 expands because of hydraulic pressure and elongation strain (as Suo Shi Fig. 7 ~ 8), make tube wall originally thinning, the 4th section 208, flexible water pipe 200 then can in the expansion space 186 of the second pipe fitting 180 dilatancy, and pass through the dilatancy of the 4th section 208, and to be formed with rear domatic 188 of necking part 184 be now jam, and be subject to External Force Acting in the reaction force of pipe joint with this appropriateness payment water pipe.
The above explanation, be only better embodiment of the present utility model, be intended to the feature of this creation clear and definite, and be not used to limit the scope that profit is implemented in this creation, the equalization change that those skilled in the art in the art do according to this creation, and the change that those skilled in that art know, the scope that this creation is contained must be belonged to.
