Abstract
The invention discloses a pipeline port device which is applied to a port position between two petroleum pipelines and comprises an inner cone and an outer sleeve. Two ends of the inner cone are of conical surface structures with identical conical degrees, the surfaces of the conical surface structures are friction surfaces, internal threads are respectively machined at two ends of the outer sleeve, turning directions of the internal threads of the two ends of the outer sleeve are opposite to each other, an annular boss is arranged on the inner wall of 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 cone, and a cone angle of each conical surface structure of the inner cone optionally ranges from 3 degrees to 5 degrees. The pipeline port device has the advantages that conical surface structures with the friction surfaces are matched with the inner walls of the petroleum pipelines frictionally, and the two petroleum pipelines are connected with each other by the outer sleeve and are fixedly locked, so that effects of locking, connecting and sealing the petroleum pipelines are realized, and stress balance of the integral pipeline port device is guaranteed.
Description
Technical field
The present invention relates to a kind of pipe interface device, belong to the petroleum pipeline technical field.
Background technique
Adopt the petroleum pipeline transfer oil, cost is low, the medium tache less wastage, 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 merchants need solve, and the solution of this problem directly has influence on the great field that oil reserve, oil transportation etc. are related to national economy.So for guarantee oil transportation safe, reduce the wasting phenomena in the course of conveying, need the pipe interface device of a kind of good stability of design, good airproof performance.
Summary of the invention
In order to solve the technical problem of petroleum pipeline sealing joint, and the problem of petroleum pipeline interface structure stability, the invention provides a kind of pipe interface device.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of pipe interface device, be applied to two sections interface positions between the petroleum pipeline, comprise inner conical-tube and outer sleeve, the two ends of described inner conical-tube are designed to the identical cone structure of tapering respectively, and the surface of cone structure is friction surface, the two ends of described outer sleeve are processed with internal thread respectively, and the rotation direction of the internal thread at two ends is opposite, inwall in the neutral position of described outer sleeve is provided with annular boss, the internal diameter of described annular boss is greater than the external diameter in described inner conical-tube neutral position, and 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 the inner conical-tube, guarantees that the tube wall of petroleum pipeline is stressed evenly.
A kind of pipe interface device of the present invention, 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 are locked, reach the effect that locking connects and seals, guarantee the stress equalization of whole piping installation.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a kind of structural drawing of pipe interface device.
Among the figure: 1, inner conical-tube; 2, outer sleeve; 3, petroleum pipeline; 11, cone structure; 21, internal thread; 22, annular boss.
Embodiment
As shown in Figure 1, the described a kind of pipe interface device of the embodiment of the invention, be applied to two sections interface positions between the petroleum pipeline 3, comprise inner conical-tube 1 and outer sleeve 2, the two ends of described inner conical-tube 1 are designed to the identical cone structure of tapering 11 respectively, and the surface of cone structure 11 is friction surface, the two ends of described outer sleeve 2 are processed with internal thread 21 respectively, and the rotation direction of the internal thread 21 at two ends is opposite, inwall in the neutral position of described outer sleeve 2 is provided with annular boss 22, the internal diameter of described annular boss 22 is greater than the external diameter in described inner conical-tube 1 neutral position, the angle of the cone angle of the cone structure 11 of described inner conical-tube 1 is the arbitrary value between the 3-5 degree, and described cone angle refers to that cone structure 11 is with respect to the drift angle in the axle center of inner conical-tube 1.
Further, the length of described inner conical-tube 1 equals the length of described outer sleeve 2, so that form stress equilibrium between outer sleeve 2 and the inner conical-tube 1, guarantees that the tube wall of petroleum pipeline 3 is stressed evenly.
A kind of pipe interface device of the present invention, 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 are locked, reach the effect that locking connects and seals, guarantee the stress equalization of whole piping installation.
It is to be noted; design of the present invention is not limited only to above embodiment, anyly conceives further improvement and distortion on the basis in the present invention, all should belong to the protection domain of the present invention's design; anyone permits without the obligee, all can not arbitrarily implement the design proposal of this patent.
