Abstract
The invention relates to a 90-degree elbow pipe joint which comprises a horizontal element (1) and a vertical element (2) which are arranged individually, wherein the horizontal element (1) at the connecting end is provided with an internal thread (11); the vertical element (2) at the connecting end is provided with a matched external thread (21); and the horizontal element (1) and the vertical element(2)are in threaded connection together. Compared with the prior art, according to the invention, through the separated individual arrangement and threaded connection arrangement of the horizontal element (1) and the vertical element (2), the vertical element can extend into the horizontal element, and the vertical element and the horizontal element are in threaded connection together, the connection firmness of the vertical element and the horizontal element is reinforced, and the connection part of the vertical element and the horizontal element is difficult to be cracked, and the 90-degree elbow pipe joint has long service life.
Description
Technical field
The present invention relates to a kind of pipe joint, relate in particular to the curved connection for bbreather pipe of a kind of 90 degree.
Background technique
The application of pipe joint in oil, liquid delivery line connect is very extensive, and the curved connection for bbreather pipe of a kind of 90 degree is wherein arranged, and can connect mutually perpendicular two pipelines and becomes and use one of pipe joint always.The curved connection for bbreather pipe of existing 90 degree is a lateral member and a direct butt welding of vertical member and fuse when concrete the manufacturing, and wherein lateral member has the passage of bending, and lateral member is provided with outside thread in the port and can be threaded with connecting pipeline.In actual use, the lateral member in the pipe joint is the precession pipeline through turning vertical member, for reaching reliable connection; The user is turn vertical member firmly often, so, and under situation about overexerting; Pipe joint is twisted into two easily and is broken, and also promptly, the soldering point between lateral member and the vertical member is twisted into two parts easily; Cause whole pipe joint to damage, product is shorter working life.Thereby the curved connection for bbreather pipe of existing 90 degree needs further improvement on manufacturing process.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of 90 degree curved connection for bbreather pipe to the existing technology present situation, and its lateral member is connected with vertical member reliably, and both joints are easy-rupturing not, has long working life.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: the curved connection for bbreather pipe of this 90 degree; It is characterized in that: comprise independent lateral member and the vertical member that is provided with; Said lateral member has internal thread at connecting end; And said vertical member has the outside thread that is complementary at connecting end, and said lateral member is threaded with vertical member.
Preferably, the inner passage of said lateral member is the L type, and the inner passage of vertical member is a straight line type, and the internal thread of said lateral member is arranged in the whole lateral part of L type inner passage, so that lateral member reaches range with the length that is threaded of vertical member.
Compared with prior art, the invention has the advantages that: connect setting through the screw fit between lateral member and the vertical member, when concrete production and processing, lateral member is threaded earlier with vertical member, and then both seam peripheries are welded; So, it is inner that vertical member has extend into lateral member, and both are threaded together, strengthened both degree of being connected firmly, and both joints are easy-rupturing not, has long working life, simultaneously, simple in structure, be easy to production and processing.

Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the structural representation of lateral member in the embodiment of the invention.
Fig. 3 is the structural representation of vertical member in the embodiment of the invention.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Like Fig. 1 ~ shown in Figure 3, the curved connection for bbreather pipe of this 90 degree comprises independent lateral member that is provided with 1 and vertical member 2;
Wherein, said lateral member 1 has L type inner passage A, has internal thread 11 at the connecting end of lateral member 1, and this internal thread 11 is arranged in the whole lateral part of L type inner passage A, referring to Fig. 2;
And said vertical member 2 has straight line type inner passage B; Vertical member 2 has the outside thread 21 that is complementary at connecting end, and during this pipe joint of reality processing, said lateral member 1 is threaded mutually earlier with the connecting end of vertical member 2; Be in the lateral part of the connecting end of the vertical member 2 L type inner passage A that extend into lateral member 1; The connecting end edge of vertical member 2 flushes with the tube wall inboard of lateral member 1, referring to Fig. 1, then; Weld seam crossing periphery to both, the pipe joint finished product that makes it to become one.
Claims (2)
1. a degree is bent connection for bbreather pipe; It is characterized in that: comprise independent lateral member (1) and the vertical member (2) that is provided with; Said lateral member (1) has internal thread (11) at connecting end; And said vertical member (2) has the outside thread (21) that is complementary at connecting end, and said lateral member (1) is threaded with vertical member (2).
2. the curved connection for bbreather pipe of 90 degree as claimed in claim 1; It is characterized in that: the inner passage (A) of said lateral member (1) is the L type; And the inner passage (B) of vertical member (2) is a straight line type, and the internal thread (11) of said lateral member (1) is arranged in the whole lateral part of L type inner passage (A).
