Fig. 3 is the partial enlarged view I of Fig. 2.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.
A kind of sealed connection device for pipeline, as illustrated in the accompanying drawings from 1 to 3, including connection swivel nut 1, locking nut 2, compression ring 3, pad
Ring 4.Compression ring 3 uses spring steel (65Mn) processing and fabricating.
Connect the boss 9 with ring circumferential direction on the internal face of swivel nut 1, the pipeline 5 of required connection is from the both ends for connecting swivel nut 1
It is inserted into, connection swivel nut 1 is set on the peripheral surface of pipeline 5, and the end face of pipeline 5 is supported with boss 9 closes.
The end face of compression ring 3 towards connection swivel nut 1 is set on the peripheral surface of pipeline 5, and gasket ring 4 is outer towards compression ring 3
End cap is located on the peripheral surface of pipeline 5, and the outer end of locking nut 2 towards gasket ring 4 is set on the peripheral surface of pipeline 5 and by gasket ring
4, compression ring 3 contains wherein, until being screwed on locking with 1 screw thread of swivel nut connect, so that gasket ring 5, compression ring 3 are being connected swivel nut
It is compressed between 12 inside of end face and locking nut, two pipelines 5 is enable to be tightly connected.
Compression ring 3 and the interface for connecting swivel nut 1 are the conical surface A6 agreed with, and the interface of gasket ring 4 and compression ring 3 is to agree with
Conical surface B7, conical surface A6 is non-intersecting on the peripheral surface of compression ring 3 with conical surface B7, i.e. the peripheral surface of compression ring 3 and locking nut 2
Inner peripheral surface formed be face contact.Compression ring 3 is offered along its week with connecting on the interface of swivel nut 1, gasket ring 4, pipeline 4
