Abstract
The utility model discloses a pipeline connector device which is applied to connector positions of two petroleum pipelines. The pipeline connector device comprises an inner conical barrel and an outer sleeve. The two ends of the inner conical barrel are respectively designed to be of a conical face structure. The conical face structures are the same in taper. The surfaces of the conical face structures are friction surfaces. Inner threads are machined on the two ends of the outer sleeve. The inner threads of the two ends are different in turning direction. An annular boss is arranged on the inner wall in the middle of the outer sleeve. The inner diameter of the annular boss is larger than the outer diameter of the middle of the inner conical barrel. The degree of a conical angle of each conical face structure of the inner conical barrel is an arbitrary value between 3 degrees and 5 degrees. The pipeline connector device is in friction fit with inner walls of the petroleum pipelines through the conical faces with the friction surfaces, and connects the two petroleum pipelines through the outer sleeve, and locks and fixes the two petroleum pipelines, so that a locking connection and sealing effect is achieved, and stress balance of the whole pipeline device is ensured.
Description
Technical field
The utility model relates to a kind of pipe interface device, belongs to the petroleum pipeline technical field.
Background technique
Adopt the petroleum pipeline transfer oil, cost is low, the medium tache waste is few, but to having relatively high expectations of pipeline and pipe joint, so in order to guarantee the stability of petroleum pipeline transfer oil, seal request, structural strength to pipe joint require just to become the important technological problems that a lot of pipe production business need to solve, and this solution of problem directly has influence on the major areas that oil reserve, oil transportation etc. are related to national economy.So for guarantee oil transportation safe, reduce the wasting phenomena in course of conveying, need the pipe interface device of a kind of good stability of design, good airproof performance.
The model utility content
In order to solve the technical problem of petroleum pipeline sealing joint, and the problem of petroleum pipeline interface structure stability, the utility model provides a kind of pipe interface device.
The purpose of this utility model is come specific implementation by the following technical programs:
a kind of pipe interface device, be applied to two sections interface positions between petroleum pipeline, comprise inner conical-tube and outer sleeve, the two ends of described inner conical-tube are designed to respectively the identical cone structure of tapering, and the surface of cone structure is friction surface, the two ends of described outer sleeve are processed with respectively internal thread, and the rotation direction of the internal thread at two ends is opposite, be provided with annular boss on the inwall in the neutral position of described outer sleeve, the internal diameter of described annular boss is greater than the external diameter in described inner conical-tube neutral position, the angle of the cone angle of the cone structure of described inner conical-tube is the arbitrary value between the 3-5 degree.
Further, the length of described inner conical-tube equals the length of described outer sleeve, so that form stress equilibrium between outer sleeve and inner conical-tube, guarantees that the tube wall of petroleum pipeline is stressed evenly.
A kind of pipe interface device described in the utility model, the conical surface by having friction surface and the inwall of petroleum pipeline carry out frictional fit, by outer sleeve, two sections petroleum pipelines are connected, and be locked, reach the effect that locking connects and seals, guarantee the stress equalization of whole piping installation.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is a kind of structural drawing of pipe interface device.
In figure: 1, inner conical-tube; 2, outer sleeve; 3, petroleum pipeline; 11, cone structure; 21, internal thread; 22, annular boss.
