Detailed description of the invention
Below in conjunction with the Figure of description provided, description is made in preferred embodiment of the present utility model.
In conjunction with shown in Fig. 1 to Fig. 4, this utility model provides a kind of ring type sealing device, for connecting two hermetically
Pipeline 1.Lateral wall outwardly formation one boss 11 of pipeline 1 end, boss 11 includes a male cone (strobilus masculinus) 12, pipeline 1 end
Medial wall is additionally provided with the inner conical surface 13 corresponding with male cone (strobilus masculinus) 12.
Ring type sealing device includes black box and latch assembly, wherein black box include sealing ring 2, middle cutting ferrule 3,
Two outer cutting ferrules 4 and two connectors 5.Latch assembly includes screw rod 6, nut 7 and two locking members 8.In the middle of in the present embodiment
The quantity of cutting ferrule 3 is one, in practical operation, when needing the pipeline 1 connected to be relatively large in diameter, can suitably increase middle card
The quantity of set 3.When the quantity of middle cutting ferrule 3 increases, the quantity of connector 5 increases the most accordingly.
Sealing ring 2 clamps between two pipelines 1 and by the distal end faces of two pipelines 1.One end of two outer cutting ferrules 4 is divided
Other one end pivot joint with two connectors 5, the other end of two connectors 5 is articulated in the two ends of middle cutting ferrule 3 respectively.Concrete, even
Fitting 5 includes that two relative connection sheets 51 and two connect post 52, and two connect post 52 compartment of terrain is fixed between two connection sheets 51,
Middle cutting ferrule 3, outer cutting ferrule 4 are articulated on connection post 52.Two outer cutting ferrules 4, middle cutting ferrule 3 and connector 5 constitute a chain knot
Structure.
Outer cutting ferrule 4 is respectively provided with the arcwall face 40,30 corresponding with the excircle of pipeline 1 with the inner side of middle cutting ferrule 3, and outward
Cutting ferrule 4 is additionally provided with arcuate groove 41,31 with the inner side of middle cutting ferrule 3, and arcuate groove 41,31 is positioned at outer cutting ferrule 4, middle cutting ferrule 3
Arcwall face 40,30 is also divided into upper and lower two parts by the centre position of short transverse.Arcuate groove 41,31 in by bottom to top by
The structure that flaring is big, the two side of arcuate groove 41,31 is the arcwall face tilted.The outside of outer cutting ferrule 4 end is provided with opening court
Outer holding tank 42, the diapire of holding tank 42 is arcwall face.
One end of locking member 8 is in circular arc corresponding with the diapire of holding tank 42, and the other end is plane.
When mounted, first the chain ring that two outer cutting ferrules 4, middle cutting ferrule 3 and connector 5 are constituted is anchored to two pipelines 1 even
The place of connecing also makes arcuate groove 41,31 be enclosed within the boss 11 of two pipelines 1, and the sidewall of arcuate groove 41,31 is close to male cone (strobilus masculinus) 12, then
Being navigated to respectively by two locking members 8 in two holding tanks 42, the diapire of locking member 8 one end in circular arc and holding tank 42 is conflicted,
Finally by screw rod 6 through two locking members 8, nut 7 is set on screw rod 6 and tightens.Nut 7 is outer cutting ferrule 4 and centre after tightening
Cutting ferrule 3 tightens up on pipeline 1, by coordinating of arcuate groove 41,31 and male cone (strobilus masculinus) 12, two pipelines 1 oppressed relatively close also
Compresses seal 2 deforms, it is achieved sealing effectiveness.Sealing ring 2 after deformation contacts with end face and the inner conical surface 13 of pipeline 1 simultaneously,
Contact area is conducive to greatly strengthening sealing effectiveness.When the intrinsic pressure F1 of pipeline 1 puts on sealing ring 2 as shown in Figure 4, and sealing ring 2 becomes
Shape also applies elastic force F2 to two pipelines 1, and two pipelines 1 are locked and cannot move, and in other words sealing ring 2 can be at two two pipelines 1
Between fill in tighter, here it is self-tightening effect.
In order to make screw rod 6 pass through, the centre of the position that outer cutting ferrule 4 end arranges holding tank 42 is that hollow out is arranged.
When black box includes multiple middle cutting ferrule 3 being sequentially connected, the two middle cutting ferrules 3 being positioned at two ends pass through respectively
Connector 5 is connected with two outer cutting ferrules 4, and connects also by connector 5 between two adjacent middle cutting ferrules 3.
