A kind of cutting ferrule Hermetical connecting structure, wherein, comprise pipeline, nut, ferrule structure, double-screw bolt, double-screw bolt and cutting ferrule adapter structure, nut internal structure, stud end structure, described ferrule structure is connected with described pipeline, makes described ferrule structure and fittings body inner conical surface form line contact sealing.Described nut is screwed on described pipeline, and the right side of close described ferrule structure, keep fixing distance with described ferrule structure, described nut inside is provided with described nut internal structure, in described double-screw bolt, be provided with described double-screw bolt and cutting ferrule adapter structure, end is also provided with described stud end structure simultaneously, install and use in process, described double-screw bolt moves forward from end in described pipeline, when described double-screw bolt and cutting ferrule adapter structure just in time run to described ferrule structure, suitable with described ferrule structure structure shape, the cutting ferrule inner cutter hole of described ferrule structure embeds the outer wall of described pipeline, described stud end structure and described nut internal structure are combined closely by the form being spirally connected.
Described a kind of cutting ferrule Hermetical connecting structure, wherein, described ferrule structure comprises arc angle outside cutting ferrule conical surface, cutting ferrule port chamfering, cutting ferrule end tapered face, cutting ferrule, cutting ferrule the other end conical surface.The angle that described cutting ferrule conical surface becomes with substantially horizontal is 13 °, the chamfering of described cutting ferrule port chamfering is that radius is the circular arc of 0.1mm, the angle that described cutting ferrule end tapered face becomes with vertical direction is 5 °, described cutting ferrule lateral arcs is that radius is the circular arc of 0.5mm, and the angle that described cutting ferrule the other end conical surface becomes with substantially horizontal is 43 °
A kind of cutting ferrule Hermetical connecting structure of the utility model, by the pipe joint of 24 ° of cone shape holes, with the cutting ferrule of sharp-pointed inner edge with play the structure setting of this three part of nut of pressuring action, make that ferrule structure that the utility model is tightly connected has simple in structure, favorable sealing property, good pressure-resistant performance, lightweight, volume is little, easy to use and the advantage such as need not weld.
Accompanying drawing explanation
Fig. 1 is a kind of cutting ferrule Hermetical connecting structure of the utility model schematic diagram.
Fig. 2 is the structural representation of the ferrule structure of a kind of cutting ferrule Hermetical connecting structure of the utility model.
Embodiment
The utility model provides a kind of cutting ferrule Hermetical connecting structure, for making the purpose of this utility model, technological scheme and effect clearer, clear and definite, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is a kind of cutting ferrule Hermetical connecting structure of the utility model schematic diagram.As shown in Figure 1, comprise pipeline 1, nut 2, ferrule structure 3, double-screw bolt 4, double-screw bolt and cutting ferrule adapter structure 5, nut internal structure 6, stud end structure 7.Described ferrule structure 3 is connected with described pipeline 1, and the operation that before formal assembling, described ferrule structure 3 is fixed on to one end of pipeline 1 is called prepackage.Described ferrule structure 3 after prepackage allows to rotate in a circumferential direction on described pipeline, but does not allow to move along axial direction.When formal assembling, described ferrule structure 3 is pushed into 24 ° of cone shape holes distortion thereupon, makes described ferrule structure 3 and fittings body inner conical surface form line contact sealing.Described nut 2 is screwed on described pipeline 1, and the right side of close described ferrule structure 3, keep fixing distance with described ferrule structure 3, described nut 2 inside are provided with described nut internal structure 6, in described double-screw bolt 4, be provided with described double-screw bolt and cutting ferrule adapter structure 5, end is also provided with described stud end structure 7 simultaneously, install and use in process, described double-screw bolt 4 moves forward from end in described pipeline 1, when described double-screw bolt and cutting ferrule adapter structure 5 just in time run to described ferrule structure 3, suitable with described ferrule structure 3 structure shapes, by the mode of tightening, it is combined closely, simultaneously, the cutting ferrule inner cutter hole of described ferrule structure 3 embeds the outer wall of described pipeline 1, one, pressure place annular groove on outer wall, thereby play reliable seal action, be conducive to sealing and prevent that described nut 2 from moving, described stud end structure 7 and described nut internal structure 6 are by the form being spirally connected, combine closely, it is closer that the structure that this kind of Placement can make to connect connects, and then enhancing sealability.
Fig. 2 is the structural representation of the ferrule structure of a kind of cutting ferrule Hermetical connecting structure of the utility model.As shown in Figure 2, arc angle 34, cutting ferrule the other end conical surface 35 outside described ferrule structure 3 cutting ferrule conical surfaces 31, cutting ferrule port chamfering 32, cutting ferrule end tapered face 33, cutting ferrule.The angle that described cutting ferrule conical surface 31 becomes with substantially horizontal is 13 °, the chamfering of described cutting ferrule port chamfering 32 is that radius is the circular arc of 0.1mm, the angle that described cutting ferrule end tapered face 33 becomes with vertical direction is 5 °, described cutting ferrule lateral arcs is that radius is the circular arc of 0.5mm, and the angle that described cutting ferrule the other end conical surface 35 becomes with substantially horizontal is 43 °.Certain described ferrule structure 3 as important composition in FERRULETYPE structure, its surface needs heat treatment, surface hardness scope is at (550~800) HV, the hard formation degree of depth is 0.03~0.05mm, core hardness scope (220~300) HV, has guaranteed that described ferrule structure 3 has enough hardness and toughness like this, guarantees that cutting edge is sharp does not damage, described ferrule structure 3 middle part elasticity are good simultaneously, to produce the resiliently deformable of middle part evagination.Need to anneal or normalized treatment with the interactional described pipeline 1 of cutting ferrule, surface hardness, below HRB80, is conducive to the incision of described ferrule structure 3 inner cutter holes like this.
