Abstract
The utility model provides a kind of hard seal combination connector, including：Fittings body and the nut for being sheathed on fittings body end, the end set that the fittings body is sheathed in nut have outer cone；It further includes transit joint, and the one end of the transit joint, which is set, has externally threaded inner cone；The end is placed in nut, is engaged by external screw thread with nut；The inner cone matches to form wedge structure with outer cone taper.The utility model devises the transit joint with external screw thread and inner cone, and transit joint is engaged by external screw thread with the nut of fittings body, and the outer cone of inner cone and fittings body matches and forms wedge structure, instead of sealing ring.After being packed into and connecting, during pipeline fluid high-pressure, sealing performance stability is more preferable, and high temperature resistant, extends the service life of pipeline fluid conveying, reduces cost.
Description
Technical field
The utility model belongs to fluid delivery system technical field, and in particular to for a kind of hard sealing group of pipeline connection
Splice grafting head.
Background technology
In fluid delivery pipeline, in tradition hose coupling as shown in Figure 1, relatively more using the mode that O-ring 4 seals,
Be in principle screw thread tightening force lower joint body 1 and another with externally threaded ordinary couplings（Do not show in figure）With intermediate O
Type circle contacts, and reaches sealing effect so as to combine closely.But in part equipment pipeline in actual use, because temperature is excessively high, O
Type circle non-refractory and deform, work long hours, cause equipment pipeline oil leak, influence to use.
Utility model content
To solve the above-mentioned problems, the utility model proposes a kind of hard seal combination connector, specific technical solution is such as
Under：
A kind of hard seal combination connector, including：Fittings body 1 and the nut 2 for being sheathed on 1 end of fittings body, feature exists
In：
The end set that the fittings body 1 is sheathed in nut 2 has outer cone 3；
It further includes transit joint 5, and the one end of the transit joint 5, which is set, has externally threaded inner cone 6；It puts the end
In in nut 2, engaged by external screw thread with nut 2；The inner cone 6 matches to form wedge structure with 3 taper of outer cone.
Further, the frustoconical bevel angle scope of the inner cone 6 and outer cone 3 is 60 ° -74 °.
The beneficial effects of the utility model are：
The utility model devises the transit joint with external screw thread and inner cone, and transit joint passes through external screw thread and fittings body
Nut engagement, the outer cone of inner cone and fittings body matches and forms wedge structure, instead of sealing ring.After connection is packed into,
During pipeline fluid high-pressure, sealing performance stability is more preferable, and high temperature resistant, extends the service life of pipeline fluid conveying, reduces
Cost.
Description of the drawings
Fig. 1 is a kind of traditional hard seal combination joint structure schematic diagram；
Fig. 2 is a kind of hard seal combination joint structure schematic diagram of the utility model.
Figure label：
1:Fittings body；2：Nut；3：Outer cone；4：Sealing ring；5：Transit joint；6：Inner cone.
Specific embodiment
Below in conjunction with the accompanying drawings and the embodiment of the utility model a kind of hard seal combination connector of the utility model is made into
One step is described in detail.
Fig. 2 is a kind of hard seal combination joint structure schematic diagram of the utility model, it includes：It fittings body 1 and is sheathed on
The nut 2 of 1 end of fittings body, it is characterised in that：
The end set that the fittings body 1 is sheathed in nut 2 has outer cone 3；
It further includes transit joint 5, and the one end of the transit joint 5, which is set, has externally threaded inner cone 6；It puts the end
In in nut 2, engaged by external screw thread with nut 2；The inner cone 6 matches to form wedge structure with 3 taper of outer cone.
When fittings body 1 and transit joint 5 combine, the outer cone 3 of connector 1 is combined with the inner cone 6 of transit joint 5, external screw thread and
Nut 2 engages, and applies certain external force using nut 2, and interior male cone (strobilus masculinus) is combined together, and forms hard sealing structure,
In one preferred scheme, the frustoconical bevel angle scope of the inner cone 6 and outer cone 3 is 60 ° -74 °, the angle ranging from cone
Angle between face and central axis, in above-mentioned angular range, sealing effect is good and saves material.
The utility model is simple in structure, good airproof performance, high temperature resistant, designs male cone (strobilus masculinus) in 1 outer end of connector, is filled with connector 5
After matching somebody with somebody, sealing effect is good, and service life is long, ensure that quality, is promoted suitable for large-scale production.
It is all to be made according to present utility model application the scope of the claims the foregoing is merely the better embodiment of the utility model
Equivalent changes and modifications should all belong to the covering scope of the utility model patent.
