Description
Technical field
The present invention relates to a kind of petroleum pipeline interface flexible connecting device based on Energy Dissipation Mechanism, particularly relate to the power consumption of a kind of entirety by elastic damping circle, radial second vibration damping, axis prevents movement from realizing flexibly connecting of pipeline and its staggered high projection, low projection and groove realize the labyrinth seal of comb tooth; Realize enhanced leaktightness, isolation impurity and protection elastic damping circle by Double seal ring, belong to pipeline connection technology research and development field.
Background technique
The connection of current petroleum pipeline interface is mainly by modes such as welding or flanges, although these modes achieve being tightly connected of pipeline to a certain extent, but also there is obvious deficiency, even if pipe joint is in being rigidly connected, though being rigidly connected of pipe joint adds the integral rigidity of connecting tube, but very easily make external damage load be transmitted to another pipeline by a pipeline, because two segment pipes are not one after all, this makes interface section be subjected to displacement variation under external load effect, even damage pipeline, tube fluid is caused to leak, this is particularly outstanding under the larger load such as earthquake.
And if harmful vibrational energy can be eliminated before being delivered to connected pipe, can available protecting connected pipe, and prevent two pipeline generation relative displacements.
Therefore, for the shortcomings such as caused fragile, easy leakage that are rigidly connected of existing petroleum pipeline interface, should consider from pipeline Placement and structure, design and replace the rigidly connected a kind of connection set of pipeline.
Summary of the invention
The present invention is directed to the shortcomings such as caused fragile, easy leakage that are rigidly connected of existing petroleum pipeline interface, provide a kind of a kind of petroleum pipeline interface flexible connecting device based on Energy Dissipation Mechanism that can effectively solve the problem.
A kind of petroleum pipeline interface flexible connecting device based on Energy Dissipation Mechanism of the present invention is by the following technical solutions:
A kind of petroleum pipeline interface flexible connecting device based on Energy Dissipation Mechanism, mainly comprise pipeline, seal ring and elastic damping circle, pipeline is divided into pipeline A and pipeline B, seal ring is divided into seal ring A and seal ring B, installs seal ring A, elastic damping circle and seal ring B successively from inside to outside between pipeline A and pipeline B; The interface section diameter of described pipeline A one end is greater than other pipeline sections, and pipeline B interface place is provided with two sections of circular grooves, and this two circular groove is respectively used to install seal ring A and seal ring B; Described seal ring A and seal ring B is " O " shape structure, selects NBR nitrile rubber seal ring; Described elastic damping circle is columnar structured, and elastic damping circle alternate has high projection and low projection, is provided with groove between high projection and low projection, and the axial length of high projection, low projection and groove is all
l, high protruding radial height is 2
l, the radial height of low projection is
l, viscoelasticity high-damping rubber material selected by elastic damping circle.
Elastic damping circle is selected viscoelasticity high-damping rubber material by the present invention, and be designed to containing groove and high, the staggered structure of low projection, at utmost transferring energy is consumed by this design, eliminate the load of connected tube, realize flexibly connecting of pipeline, concrete function and implementation as follows: one is realize overall power consumption, namely the viscoelasticity had by viscoelasticity high-damping rubber and high damping characteristic carry out vibration damping to pipe vibration, when pipeline A vibrates, vibrational energy is delivered to elastic damping circle by pipeline A, at this moment vibrational energy will by two kinds of form consumption, partial vibration energy is consumed on the one hand by friction in the viscosity between rubber molecular chain, on the other hand in elastic damping circle, pipeline B and the pipeline A in outside are equivalent to restraining plate, when pipeline A vibrates, pipeline A and pipeline B plays the effect of constraint elastic damping circle motion, the elastic damping circle of constraint is subject to shear action, make the vibrational energy in elastic damping circle by being converted into heat energy mode to consume, two is realize radial second vibration damping, when pipeline A vibrates, high projection on compressing elastic damping circle is deformed, the effect of once power consumption and vibration damping is played by high protruding compressive strain, when the amplitude of pipeline A strengthens, the high protruding basis of compression will impel low projection that compressive strain occurs, low projection can play again the effect of secondary energy consumption and vibration damping when compressive strain, and when compressing low projection, the high projection in local can be made to rub, by vibrational energy with the form consumption of heat energy with low projection, three is prevent from moving axially, and namely by the protruding shear deformation under compression of the height on elastic damping circle, increases the frictional force between pipeline A and high projection, prevents pipeline A and pipeline B from occurring to move to axial, four is effects of sealing pipeline, namely the sealing of fluid is realized by high projection, low projection and groove therebetween, when the fluid in pipeline leaks through seal ring A, leakage flow cognition is temporarily stored in region between groove and two high projections, because high projection, low projection and groove are for being staggered, elastic damping is made to enclose the effect of comb tooth labyrinth seal.
The present invention installs seal ring A and seal ring B two seal rings at pipe joint, by this structural design, there is following functions: one is enhanced leaktightness effect, namely prevent tube fluid from leaking into elastic damping circle by seal ring A, again leaked into outside pipe to the fluid in elastic damping circle by seal ring B Leakage prevention; Two are the outer impurity of isolated tube and protect elastic damping circle, namely prevent from managing outer impurity by seal ring B and enter into elastic damping circle and reduce its energy-dissipating property, and prevent impurity from entering in pipe by seal ring A, pollute tube fluid.
The invention has the beneficial effects as follows: by material be viscoelasticity high-damping rubber, structure is containing groove and the entirety power consumption of the staggered elastic damping circle of high and low projection, radial second vibration damping, axially prevents movement from utmost consuming transferring energy, eliminate the load of connected tube, realize flexibly connecting of pipeline, and play the effect of comb tooth labyrinth seal by its staggered high projection, low projection and groove; The effect of enhanced leaktightness, isolation impurity and protection elastic damping circle is realized by Double seal ring design.
