Abstract
The utility model provides a hydraulic pressure connects body structure with steel pipe, belong to hydraulic pressure connect with the connection technology field of steel pipe, its structure includes that hydraulic pressure connects and the steel pipe, tail end that hydraulic pressure connects is seted up flutedly, and the steel pipe inserts in the recess that hydraulic pressure connects and be as an organic whole through copperwelding rod and the melting welding of hydraulic pressure joint. After melting welding is accomplished, the central axis coincidence in the the central axis of steel pipe that hydraulic pressure connects. Compared with the prior art, the utility model relates to a rationally, adopt the copperwelding rod as an organic whole with hydraulic pressure joint and steel pipe melting welding, the melting welding in -process can not produce blowholes to can not produce reveals the phenomenon, simultaneously, still need not to do and suppressing the test, work efficiency is high, and the qualification rate is also high.
Description
Technical field
The utility model relates to joint in hydraulic equipment and steel pipe, the specifically integrative-structure of a kind of hydraulic joint and steel pipe.
Background technique
At present, in hydraulic equipment on the market, steel pipe and joint all adopt docking argon arc welding, the shortcoming existed easily produces sand holes in welding process, cause leakage of oil, and each butt welding also needs to suppress experiment later, not only inefficiency, also cannot ensure the quality after welding.
For this reason, design the integrative-structure of a kind of hydraulic joint and steel pipe, solve the problems referred to above.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides the integrative-structure of a kind of hydraulic joint and steel pipe.
The utility model solves the technological scheme that its technical problem adopts:
An integrative-structure for hydraulic joint and steel pipe, comprises hydraulic joint and steel pipe, and the tail end of described hydraulic joint offers groove, steel pipe insert hydraulic joint groove in and be integrated with hydraulic joint melting welding.
Prioritizing selection, described hydraulic joint and steel pipe are integrated by copperwelding rod melting welding.
Further, the central axes of described hydraulic joint is in the central axis of steel pipe.
Further, described hydraulic joint is metric system internal thread 24 degree cone with o circle joint.
The beneficial effect that the integrative-structure of a kind of hydraulic joint of the present utility model and steel pipe is compared with prior art produced is:
The utility model is reasonable in design, adopts copperwelding rod hydraulic joint and steel pipe melting welding to be integrated, can not produce sand holes, thus can not produce leakage phenomenon in fusion process; Meanwhile, also without the need to suppressing test, working efficiency is high, and up-to-standard rate is also high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the utility model hydraulic joint.
In figure, 1, hydraulic joint, 1-1, groove, 2, steel pipe, 3, copperwelding rod.
Embodiment
Below in conjunction with accompanying drawing 1, the integrative-structure of a kind of hydraulic joint of the present utility model and steel pipe is described in detail below.
As shown in Figure 1, the integrative-structure of a kind of hydraulic joint of the present utility model and steel pipe, its structure comprises hydraulic joint 1 and steel pipe 2, and the tail end of described hydraulic joint 1 offers groove 1-1, is integrated in the groove 1-1 that steel pipe 2 inserts hydraulic joint 1 by copperwelding rod 3 and hydraulic joint 1 melting welding.
After melting welding completes, the central axes of described hydraulic joint 1 is in the central axis of steel pipe 2.
It should be noted that, above-mentioned hydraulic joint 1 is metric system internal thread 24 degree cone with o circle joint.
In the course of working of reality, adopt full-solid induction heating plant, make copperwelding rod 3 be melted in hydraulic joint 1 and the joint gap of steel pipe 2, can not sand holes be produced after melting welding completes, also not need to carry out bulge test.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within guiding theory of the present utility model, but these embodiments are included within scope of the present utility model.
