The sealing element contradicted with card outer wall.
By using above-mentioned technical proposal, there are aperture slots on cutting ferrule, convenient for cutting ferrule to be set on bellows, later
It compresses cutting ferrule and is by welding connected and fixed cutting ferrule and bellows, it is ensured that the connective stability between it and sealing
Property, the setting of snap ring can further increase the bonding strength between cutting ferrule and bellows, and spacing ring is angularly disposed to make its periphery
The tapered structure of wall, when connecting seat is sheathed on the outside of cutting ferrule, and is connect with the wherein threaded one end of connector, the end of connector
Inclined-plane on the inside of face and connecting seat generates extruding to spacing ring so that and the periphery wall of inclined-plane and spacing ring realizes that the conical surface seals firmly,
And the inside portion sealing surface of sealing element can be realized with cutting ferrule periphery wall and contradict sealing, to have the function that dual-seal, due to
Sealing element is made it not influence to seal because expanding with heat and contract with cold the problem of by cutting ferrule periphery wall and connector internal perisporium radial compression
Property.
The utility model is further arranged to：The sealing element includes gum cover, is set on gum cover internal perisporium there are four card slot, is blocked
Slot is arranged along gum cover internal perisporium circular array, and graphite ring plate is equipped in card slot
By using above-mentioned technical proposal, graphite ring plate is directly contradicted with cutting ferrule periphery wall, graphite ring plate into it is certain from
Lubricant effect, frictional resistance is small, can reduce in connector screwing operations, the possibility of sealing element inner wall abrasion, and avoids rotation
In tight rotation process, sealing element generates the possibility of excessive deformation, thus under the premise of ensureing leakproofness, when improving its sealing
Long, graphite ring plate is the ring petaloid of multi-disc, convenient for making graphite ring plate be contradicted always with cutting ferrule by the elasticity of gum cover.
The utility model is further arranged to：It is additionally provided with gasket seal between the connector and connecting seat.
By using above-mentioned technical proposal, connecting seat can be nut, and connector can be the twin adapter of external thread type, close
Gasket is sheathed on connector, can further increase the leakproofness between connector and connecting seat.
