The invention has the beneficial effects as follows:
1, stable connection and firmly.
The often group cover contact structure of the present invention to original sleeve is transformed, namely on the basis of existing little diametric plane 17, expansion face 13, contraction front 11, big diametral plane 12 is added between expansion face 13, contraction front 11, thus considerably increase the area of contact of withholding, thus make flexible composite high pressure pipeline joint more stable and firm.
The present invention transforms original tack core pipe, large end endoporus by tack core pipe is set to horn mouth, at least two places are provided with for installing the seal groove of seal ring in crimp segment, small end endoporus is set to chamfering, small end end face is set to rounding 32, rounding is set at small end outer peripheral surface; Make joint reduce flow resistance greatly in the application of conveying high-pressure liquid, considerably increase the stability of flexible composite high pressure pipeline joint.
2, good seal performance, decreases leakage.
The present invention outside large end endoporus of silk core pipe and small end endoporus adds chamfering respectively, two place's roundings are added respectively at small end outer peripheral surface, joint is made to reduce flow resistance greatly in the application of conveying high-pressure liquid, increase by two places for installing the seal groove of seal ring in crimp segment simultaneously, before actual fastening pipe joint, seal ring is installed, in the application of conveying high-pressure liquid, flexible composite high pressure pipeline joint sealing performance is increased greatly, the fabulous leakage decreasing flexible composite high pressure pipeline joint.
