Abstract

The utility model discloses a 90-DEG elbow pipe joint. The 90-DEG elbow pipe joint comprises a transverse piece (1) and a vertical piece (2), which are independently arranged, wherein an internal thread (11) is formed at a connecting end of the transverse piece (1); an external thread (21) which is matched with the internal thread is formed at the connecting end of the vertical piece (2); and the transverse piece (1) is in threaded connection with the vertical piece (2). Compared with the prior art, the 90-DEG elbow pipe joint has the advantages that by separate and independent arrangement and threaded connection of the transverse piece and the vertical piece, the vertical piece can extend into the transverse piece, the transverse piece and the vertical piece are in threaded connection, the connection firmness of the transverse piece and the vertical piece is improved, a connecting part of the transverse piece and the vertical piece is difficult to break, and the 90-DEG elbow pipe joint is long in service life.

Description

The curved connection for bbreather pipe of a kind of 90 degree

Technical field

The utility model relates to a kind of pipe joint, relates 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 commonly use one of pipe joint.The curved connection for bbreather pipe of existing 90 degree is a lateral member and a direct butt welding of vertical member and be connected 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, lateral member in the pipe joint is the precession pipeline by turning vertical member, for reaching reliable connection, the user is turn vertical member firmly often, so, in situation about overexerting, pipe joint is twisted into easily two and is broken, and i.e., 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 in manufacturing process.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of 90 degree curved connection for bbreather pipe for the prior art present situation, and its lateral member is connected with vertical member reliably, and both joints are easy-rupturing not, has long working life.

The utility model solves the problems of the technologies described above the technological scheme that adopts: the curved connection for bbreather pipe of this 90 degree, it is characterized in that: comprise independent lateral member and the vertical member that arranges, described lateral member has internal thread at connecting end, and described vertical member has the outside thread that is complementary at connecting end, and described lateral member and vertical member are threaded.

Preferably, the inner passage of described lateral member is L-type, and the inner passage of vertical member is straight line type, and the internal thread of described 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 utility model has the advantage of: connect setting by the Screw assembly between lateral member and the vertical member, when concrete production and processing, lateral member and vertical member are threaded first, and then both seam peripheries are welded; So, it is inner that vertical member has extend into lateral member, and both are threaded, and 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. 2 is the structural representation of lateral member among the utility model embodiment.

Fig. 3 is the structural representation of vertical member among the utility model embodiment.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Such as Fig. 1～shown in Figure 3, the curved connection for bbreather pipe of this 90 degree comprises independent lateral member 1 and the vertical member 2 that arranges;

Wherein, described 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 described vertical member 2 has straight line type inner passage B, vertical member 2 has the outside thread 21 that is complementary at connecting end, during actual this pipe joint of processing, described lateral member 1 is threaded mutually first 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

1. spend curved connection for bbreather pipe for one kind 90, it is characterized in that: comprise independent lateral member (1) and the vertical member (2) that arranges, described lateral member (1) has internal thread (11) at connecting end, and described vertical member (2) has the outside thread (21) that is complementary at connecting end, and described lateral member (1) is threaded with vertical member (2).

2. as claimed in claim 1 90 spend curved connection for bbreather pipe, it is characterized in that: the inner passage (A) of described lateral member (1) is L-type, and the inner passage (B) of vertical member (2) is straight line type, and the internal thread (11) of described lateral member (1) is arranged in the whole lateral part of L-type inner passage (A).
