The utility model discloses an axial is spacing and sealed separately to be realized, gos back the accessible increase simultaneously and sets up the packing ring and realize avoiding the harm to the body to effectively releasing the inside torsion that produces under the spacing circumstances of axial again when tightening, is particularly useful for in the connection of the body of plastics material.
Description
Technical field
This utility model relates to pipe connector lug field, particularly relates to a kind of ferrule-type compression joint.
Background technology
In wine selling machine, by self priming pump the wine in fat extracted out and pass through rustless steel pipeline, valve etc. and deliver to wine outlet.So
And the main material of the self priming pump pump housing is plastics, two ends are metal tubes, if with traditional metal ferrule joint, can easily send out after tightening
Raw following problem: if the first screwing force is big, the axial and circumferential of connecting tube all will be fixing, now, tighten the torsion of generation
To can not get release, and torsion will be transferred mainly to pump housing end, Yi Qi cracks into and out of pipe root, thus causes brokenly
Bad；If the second screwing force is little, the snap ring of its built-in tapered collar structure can not play effective sealing function and make
Become leakage, even can not play the axial limiting to body, cause body to rotate freely.
Utility model content
This utility model solves the technical problem that to be to provide and a kind of solves axial limiting and sealing being realized respectively of the problems referred to above
Ferrule-type compression joint.
This utility model solves the technical scheme is that ferrule-type compression joint of its technical problem, including the connection being coaxially disposed
Body, nut, snap ring and sealing ring, one end of connector and nut threaded engagement, snap ring and sealing ring are arranged on even
Between junctor and nut, snap ring is tapered collar structure, and the tip of snap ring is towards screw cap end, on the trepanning of nut
Be provided with chamfering towards the side of snap ring, chamfering coordinates with the most advanced and sophisticated of snap ring；The one end coordinated with nut on connector
Being provided with seal groove, sealing ring is placed in seal groove.
Further: also include packing ring, packing ring is arranged between snap ring and connector, and the end of packing ring and connector
Face is for being slidably matched.
Further: described packing ring is made up of polytetrafluoroethylmaterial material.
Further: nut, snap ring, sealing ring and packing ring are all set on the connected tube of same one end, at connector
The one end coordinated with nut is provided with supports friction tight step with connected tube end.
Further: the two ends of described connector are symmetrical structure, nut, snap ring, sealing ring and packing ring all have two,
And the two ends being arranged on connector that nut, snap ring, sealing ring and packing ring are corresponding respectively.
The beneficial effects of the utility model are: in this utility model, and snap ring acts primarily as axial limiting effect, and sealing function
Being realized by sealing ring, it is achieved that being implemented separately of axial limiting and sealing, therefore, when assembling, snap ring has had only to
To the axial limiting of connected tube, can be without playing sealing function, thus can be more to the pressure of snap ring when assembling
Little, and then reduce the torsion screwing nut.It addition, arrange gasket construction also by increase, connector and nut screw thread can be reduced
The resistance that rotates in a circumferential direction during cooperation, also can effectively transmit axial compressive force simultaneously.Ferrule-type compression joint described in the utility model exists
Frictional resistance in whole circumference, well below legacy card sleeve type pipe joint, can effectively be released again in the case of realizing axial limiting
Put the inside torsion produced when tightening, it is to avoid the infringement to body, in the connection of the body being particularly suited for plastic material.
Accompanying drawing explanation
Fig. 1 is the explosive view of this utility model ferrule-type compression joint；
Fig. 2 is the sectional view of this utility model ferrule-type compression joint；
Figure is labeled as: connector 1, nut 2, chamfering 21, snap ring 3, packing ring 4, sealing ring 5, connected tube 6,
Step 7, seal groove 8.
Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, ferrule-type compression joint described in the utility model, including the connector 1 being coaxially disposed, spiral shell
Cap 2, snap ring 3 and sealing ring 5, one end of connector 1 and nut 2 threaded engagement, snap ring 3 and sealing ring 5 set
Putting between connector 1 and nut 2, snap ring 3 is tapered collar structure, the tip of snap ring 3 towards nut 2 end,
On the trepanning of nut 2, the side towards snap ring 3 is provided with chamfering 21, and chamfering 21 coordinates with the most advanced and sophisticated of snap ring 3；
The one end coordinated with nut 2 on connector 1 is provided with seal groove 8, and sealing ring 5 is placed in seal groove 8.
Wherein, snap ring 3 is set to tapered collar structure, and the most as shown in fig. 1, when assembling, its tip is towards spiral shell
Cap 2 end and the chamfering 21 being partially disposed on the upper trepanning of nut 2 correspondence at tip, during assembling, by the axial shifting of nut 2
Dynamic, chamfering 21 snap ring 3 is extruded to the paste on wall tight fit with connected tube 6, and then limit the axle of connected tube 6
To movement.Under normal circumstances, on nut 2, the inwall of trepanning is above-mentioned in addition to arranging chamfering towards snap ring 3 side except using,
Whole inwall can be configured with the ramp structure of certain gradient, and by the periphery skew wall of slope with snap ring 3
Coordinate.
It addition, also can arrange packing ring 4 in this utility model, and the end face of packing ring 4 and connector 1 is for being slidably matched, so
During assembling, packing ring 4 also will not increase bigger circumferential resistance while transmission axial compressive force, therefore can effectively release
Put the inside torsion produced during assembling, it is to avoid the infringement to body；It is particularly suited for having the connected of one end or two ends
Pipe is the situation of plastic tube.
It is furthermore preferred that described packing ring 4 can be made up of polytetrafluoroethylmaterial material；Polytetrafluoroethylmaterial material has less frictional resistance
Relative slip when coefficient, more conducively packing ring 4 coordinate with the end face of connector 1, it is ensured that when axial force is bigger, its circumference
Frictional resistance is the least.Certainly, it is possible to packing ring 4 made by the material using other coefficient of frictional resistance less.
This utility model is when practical set, as shown in Figures 1 and 2, general, nut 2, snap ring 3, sealing ring
5 and packing ring 4 be all set on the connected tube 6 of same one end, be provided with in one end that connector 1 coordinates with nut 2 and connected
Friction tight step 7 is supported in adapter 6 end；In connected tube 6 is inserted into connector 1 and the end face of connected tube 6 and step 7
Push against cooperation, realize sealing effectiveness by sealing ring 5 simultaneously.Then by screwing nut 2, snap ring 3 is compressed, makes
Obtain snap ring 3 to be packed tightly by connected tube 6, play the axial limiting to connected tube 6.
It is furthermore preferred that the two ends of connector 1 may be configured as symmetrical structure in the present invention, corresponding nut 2, snap ring 3, close
Seal 5 and packing ring 4 all have two, and the company of being arranged on that nut 2, snap ring 3, sealing ring 5 and packing ring 4 are corresponding respectively
The two ends of junctor 1.
