Abstract

The utility model discloses a threaded joint comprising a first threaded connection section (1), an outer hexagon middle section (2) and a second threaded connection section (3) which are integrated in sequence. An axial through hole (6) is provided in the threaded joint, an end opening of the first threaded connection section (1) is provided with a bell mouth (5) for sealing with a conical surface of a pipeline, a larger diameter end of the bell mouth (5) is positioned at the end opening, and a corresponding end part of the pipeline which is connected to the bell mouth is a truncated cone fit with the bell mouth (5). By employing the structure, since a sealing structure of the conical surface is adopted by a connection part of an exterior pipeline and the threaded joint, sealing rings are not needed, the structure is simple, the assembling is convenient, the production efficiency is greatly improved, and the production cost is lowered.

Description

Inipple
Technical field
The utility model relates to the auto parts machinery technical field, specifically is a kind of inipple for automobile engine system.
Background technique
Inipple refers to threaded pipe joint, is modal a kind of pipe fitting.The inipple of prior art, its two ends are suitable for connecting other parts or other pipeline in the fluid system, its two ends are for having externally threaded linkage section, and middle for profile is the intermediate section of outer-hexagonal shape, spanner can be installed inipple in the intermediate section application of force.But there is following shortcoming in the inipple of this structure: because one of them linkage section of inipple is used for connecting tube, joint external application cutting ferrule tightens up, and the pipeline end face is planar end surface, therefore, and in order to guarantee sealability, must between pipeline and inipple, end-face seal ring be set, like this, the one side complex structure, part is many, complexity is installed, reduces manufacturing efficiency; On the other hand, the poor sealing performance of cost height, end face seal.
The model utility content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, easy to assembly, can enhance productivity and the better inipple of sealability.
For solving the problems of the technologies described above, the inipple that the utility model provides, comprise first section of being threaded, outer-hexagonal intermediate section and second section of being threaded that are connected as a single entity successively, has axial hole in the inipple, the port of described first section of being threaded have for the horn mouth of pipeline conical surface seal, bell-mouthed larger diameter end is in the port, and the end of the pipeline that is attached thereto accordingly is the Rotary-table that matches with horn mouth.
Have at least one by-pass hole radially on described second section of being threaded, by-pass hole communicates with axial hole.
Described by-pass hole is three, and is uniform along the excircle direction of second section of being threaded.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) because the sealing configuration of conical surface seal has been adopted in the joint of external pipeline and inipple, therefore, saved seal ring on the one hand, simple in structure, easy to assembly, enhance productivity greatly; Also reduced cost of production on the other hand;
2) in addition, after second section of being threaded is provided with by-pass hole, can increase the fluid flow in the inipple.
Description of drawings
Fig. 1 is the structural representation of the utility model inipple.
Fig. 2 is the sectional structure schematic representation of the utility model inipple.
Fig. 3 is the structural representation of A-A direction among Fig. 1.
Wherein: 1, first section of being threaded; 2, outer-hexagonal intermediate section; 3, second section of being threaded; 4, by-pass hole; 5, horn mouth; 6, axial hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of the utility model inipple of Fig. 1~shown in Figure 3 as can be known, it comprises first section of being threaded 1, outer-hexagonal intermediate section 2 and second section of being threaded 3 that is connected as a single entity successively, has axial hole 6 in the inipple, the port of described first section of being threaded 1 have for the horn mouth 5 of pipeline conical surface seal, the larger diameter end of horn mouth 5 is in the port, and the end of the pipeline that is attached thereto accordingly is the Rotary-table that matches with horn mouth 5.
Have at least one by-pass hole 4 radially on described second section of being threaded 3, by-pass hole 4 communicates with axial hole 6.In this practical example, described by-pass hole 3 is three, and is uniform along the excircle direction of second section of being threaded 3.

Claims (3)

1. inipple, comprise first section of being threaded (1), outer-hexagonal intermediate section (2) and second section of being threaded (3) that are connected as a single entity successively, has axial hole (6) in the inipple, it is characterized in that: the port of described first section of being threaded (1) have for the horn mouth (5) of pipeline conical surface seal, the larger diameter end of horn mouth (5) is in the port, and the end of the pipeline that is attached thereto accordingly is the Rotary-table that matches with horn mouth (5).
2. inipple according to claim 1, it is characterized in that: have at least one by-pass hole (4) radially on described second section of being threaded (3), by-pass hole (4) communicates with axial hole (6).
3. inipple according to claim 2, it is characterized in that: described by-pass hole (3) is three, and is uniform along the excircle direction of second section of being threaded (3).
