It with AISI standard, can be exchanged with the product of most union manufacturers, be suitable for threaded end, docking bonding tip and without pressure
Power seals end and is coupled, which when in use, is unable to satisfy the effective sealing effect for increasing union, causes to install it
Occur stream oil, the effect for reducing the practicability of union and using between union and oil pipe afterwards, and the use that user is not achieved needs
It asks.
Utility model content
The purpose of this utility model is to provide a kind of high sealing unions, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of high sealing union, including female fitting,
Trapezoidal nut and convex joint, the female fitting are connected by trapezoidal nut with female fitting screw thread, and the female fitting and convex joint are tight
The junction of closely connected conjunction, the female fitting and convex joint is connected with the second sealing ring, the inner wall one of the female fitting and convex joint
End is provided with recess, and the inner wall of the recess is provided with internal screw thread, the female fitting and convex joint and the junction of oil pipe is connected with
First sealing ring, the outer wall of the trapezoidal nut is affixed, and there are three convex blocks.
Compared with prior art, the utility model has the beneficial effects that the high sealing union, by female fitting and convex connecing
The junction that the second sealing ring, female fitting and convex joint and oil pipe is fixed in the junction of head be fixed the first sealing ring it
Between cooperation, it is effective convenient for increasing the leakproofness that union is waited when in use, while increasing female fitting and convex joint on union and connecting
Stability and sealing effect when connecing, and it is relatively labor-saving when installation connection, the practicability and using effect of union are increased,
The leakage efficiency that union is waited when in use has been turned up, has greatly met the use demand of user.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is female fitting and convex joint attachment structure schematic diagram in the utility model Fig. 1.
In figure: 1, female fitting, 2, trapezoidal nut, 3, convex joint, 4, internal screw thread, 5, convex block, 6, recess, the 7, first sealing
Circle, the 8, second sealing ring.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of high sealing union, female fitting 1, trapezoidal spiral shell
Mother 2 and convex joint 3, which are used to cooperate, is combined into union, including female fitting 1, trapezoidal nut 2 and convex joint 3, and elastic nut 2 is used for
Female fitting 1 and convex joint 3 are connected, female fitting 1 is connected by trapezoidal nut 2 with 3 screw thread of female fitting, and convex joint 3 and female fitting 1 are used
In opening up recess 6, female fitting 1 and convex joint 3 are fitted closely, and the second sealing ring 8 is used to be fixed on the inner wall bottom end of recess 6, recessed
The junction of connector 1 and convex joint 3 is connected with the second sealing ring 8, and tubing round thread is fixed on the inside of recess 6,1 He of female fitting
Inner wall one end of convex joint 3 is provided with recess 6, and recess 6 is used in its inner wall tapped 4, and the inner wall of recess 6 is provided with internal screw thread
4, the junction of female fitting 1 and convex joint 3 and oil pipe is connected with the first sealing ring 7, and the first sealing ring 7 is for being fixed on female fitting
