Abstract
The invention discloses a petroleum pipeline with a sealing structure comprising ring grooves. The petroleum pipeline comprises a body. Inner conical surfaces with identical conical degrees and equal lengths are respectively arranged at ports of two ends of the body, the surfaces of the inner conical surfaces are smooth, a cone angle between each inner conical surface and the axis of the body ranges from 3 degrees to 5 degrees, a first ring groove and a second ring groove are formed in each inner conical surface, and the diameter of each first ring groove is larger than that of each second ring groove; a first sealing ring is mounted in each first ring groove in an embedded manner, and a second sealing ring is mounted in each second ring groove in an embedded manner. The petroleum pipeline with the sealing structure comprising the ring grooves has the advantages that a sealing effect realized by the sealing rings replaces a rubbing sealing effect, the stability of the integral petroleum pipeline can be affected by the service life of each sealing ring during usage, but the design cost is lowered, and the stability of the integral petroleum pipeline can be improved by means of enhancing the oxidation resistance and the corrosion resistance of each sealing ring; requirements of different service environments on the petroleum pipeline can be met, and the market demand is extensive.
Description
Technical field
The present invention relates to a kind of annular groove sealing configuration petroleum pipeline, 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, the claimant designs the petroleum pipeline interface device of a kind of good stability, good airproof performance, and has applied for a kind of cone-shaped interface petroleum pipeline on the same day in the application.But the friction surface structure of this petroleum pipeline structure, though can guarantee good sealing property, but design cost is also higher, can only be applicable to the Environmental Conditions that minority is had relatively high expectations to sealing, stability, stress equilibrium, field for common technical requirements, user cost is too high, thus be necessary this application is improved accordingly, so that it is applicable to the Environmental Conditions not high to technical requirements.
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 annular groove sealing configuration petroleum pipeline.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of annular groove sealing configuration petroleum pipeline, comprise body, the two ends interface position of body is respectively equipped with that tapering is identical, the inner conical surface of equal in length, the surface of described inner conical surface is smooth surface, and described inner conical surface is the 3-5 degree with respect to the angle of the cone angle in body axle center, be provided with first annular groove and second annular groove at each described inner conical surface, the diameter of described first annular groove is greater than the diameter of described second annular groove; Embedded first seal ring that is equipped with in described first annular groove, embedded second seal ring that is equipped with in described second annular groove.
The cross section of described first seal ring is circular.
The cross section of described second seal ring is rectangle.
A kind of annular groove sealing configuration petroleum pipeline of the present invention, adopt the seal ring sealing to replace friction sealed, though in the process of using since the life-span of seal ring influenced the stability of whole petroleum pipeline, but reduced design cost, can improve by anti-oxidant, the erosion-resisting performance that improves seal ring, also can satisfy different Environmental Conditions to the requirement of petroleum pipeline, the market demand is widely arranged.
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 annular groove sealing configuration petroleum pipeline.
Among the figure: 1, body; 2, inner conical surface; 3, outside thread; 41, first annular groove; 42, second annular groove; 51, first seal ring; 52, second seal ring.
Embodiment
As shown in Figure 1, the described a kind of annular groove sealing configuration petroleum pipeline of the embodiment of the invention, comprise body 1, the two ends interface position of body 1 is respectively equipped with that tapering is identical, the inner conical surface of equal in length 2, the surface of described inner conical surface 2 is smooth surface, and described inner conical surface 2 is the 3-5 degree with respect to the angle of the cone angle in body axle center, be provided with first annular groove 41 and second annular groove 42 at each described inner conical surface 2, the diameter of described first annular groove 41 is greater than the diameter of described second annular groove 42; Embedded first seal ring 51 that is equipped with in described first annular groove 41, embedded second seal ring 52 that is equipped with in described second annular groove 42.
The cross section of described first seal ring 51 is circular.
The cross section of described second seal ring 52 is rectangle.
The two ends of body respectively are provided with outside thread 3, and the rotation direction of the outside thread 3 at two ends is identical.
A kind of annular groove sealing configuration petroleum pipeline of the present invention, adopt the seal ring sealing to replace friction sealed, though in the process of using since the life-span of seal ring influenced the stability of whole petroleum pipeline, but reduced design cost, can improve by anti-oxidant, the erosion-resisting performance that improves seal ring, also can satisfy different Environmental Conditions to the requirement of petroleum pipeline, the market demand is widely arranged.
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.
