Third sealing ring, the outer rim of third sealing ring and the inside face contact of connecting tube, the second sealing ring and tube body are arranged in groove
Conical side surface contact, the end face of the first sealing ring is contacted with the end face of tube body.
As a kind of optimal technical scheme of the utility model, externally threaded one end is not set on the swivel nut and is arranged with rubber
Set.
As a kind of optimal technical scheme of the utility model, the material of the third sealing ring is felt, the second sealing
The material of circle is rubber, and the material of the first sealing ring is metal.
As a kind of optimal technical scheme of the utility model, second sealing ring is cone, the second sealing ring
Male cone (strobilus masculinus) is consistent with the taper of connecting tube inner conical surface, and the taper of male cone (strobilus masculinus) of inner conical surface and tube body of the second sealing ring is consistent.
Compared with prior art, the utility model has the beneficial effects that this thin wall metal pipeline pipe connecting unit, connection construction behaviour
Make extremely simplicity, is easy to implement, rigid seal is combined with flexible sealing, and good seal performance, high reliablity can also be torn open repeatedly
Dress, the performance repeatedly used can guarantee higher consistency, and the rubber sleeve of setting can increase friction, during installation can be effective
It prevents from skidding, practicability is high.
