Description
Technical field
Pipe technology field is the utility model is related to, more particularly, to a kind of novel pipeline thread seal joint.
Background technology
At present, pipeline is used for the conveying of fluid in the field such as industrial, civilian extensive use, main body, but due in pipeline
In the presence of certain pressure, in general connection method cannot be guaranteed the sealing between pipeline and pipeline, it is easy to cause pipeline to connect
The loosening or pull-off at place are connect, so as to cause the leakage of pipeline, is caused any property loss.
The tooth of per inch 8 or the sealing structure of 10 teeth used at present, when large diameter pipeline is installed in the presence of easy thread alternating
Problem so that screw thread is damaged when tightening, and causes joint seepage.And socket joint bonding and socket joint used by large diameter pipeline
Its sealing reliability of locking key joint design cannot be guaranteed.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provides a kind of novel pipeline thread seal and connect
Head.
The new technical scheme of the utility model is：A kind of novel pipeline thread seal joint, including pipeline, pipe ends point
It is not provided with interface and bellmouth, the outer surface of described interface is provided with trapezoidal external screw thread, described No.1 tooth and No. two teeth
Center spacing is 12.7mm, and described bellmouth inner surface setting has trapezoidal internal thread；Set respectively between described interface and bellmouth
Sealing structure is equipped with, described sealing structure includes being arranged on the inner seal structure of bellmouth end and the external seal knot of interface front end
Structure；Described inner seal structure includes inner sealing surface and sealed groove, and described outer seal configuration is recessed including external seal face, wedge shape
Groove, end bosses, flexible " O " type rubber ring in described wedge-shaped impression.
The value of described trapezoidal externally threaded trapezoidal external screw thread flank angle is 5 ° ~ 15 °.
Described trapezoidal external screw thread matches with trapezoidal internal thread.
Described sealed groove matches with end bosses, and described end bosses angle is 75 ° ~ 85 °.
Described elasticity " O " type rubber ring 9 is buckled in wedge-shaped impression, and the wedge-shaped impression flank angle of wedge-shaped impression is negative angle
Degree, angle are 5 ° ~ 15 °.
The beneficial effects of the utility model are：Screw thread is not easy thread alternating, easy for installation, good sealing effect, and tensile strength is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sealing surface detail drawing of the present utility model.
Wherein：1 is pipeline, and 2 be interface, and 3 be bellmouth, and 4 be trapezoidal external screw thread, and 41 be No.1 tooth, and 42 be No. two teeth, and 5 are
