Description
Technical field
The present invention relates to oil equipment technical field, more particularly to a kind of damping dress set based on petroleum pipeline bending place
Put.
Background technology
Increasingly highlighted with the development of national economy, the advantages of pipeline oil transportation, oil pipeline is substantially all using carbon
Plain steel seamless steel tube, vertical masonry joint electric-resistance-welded steel pipe and spiral weld steel pipe, the laying of oil pipeline are typically maked somebody a mere figurehead or buried using ground
Ground two ways.China is completed tens of thousands of more kilometers of oil-gas pipeline, many conduit runnings in its central and east near or above 20 years,
Limited, the reason such as design, construction level, fault in material, damage for running for many years, managed by building condition of technology and economy at that time
The many hidden danger of road security presence.During petroleum transportation, it is necessary to using substantial amounts of petroleum pipeline, these petroleum pipelines or bury
Underground is located at, or is erected at the position for having certain altitude apart from ground, tube seat is set on ordinary circumstance support of pipelines, will
Pipeline is placed in tube seat and is supported, and tube seat has certain height distance with ground, but for the limitation of some landform, has
Relatively closely some are higher apart from ground for a little tube seats, thus need to manufacture the support of pipelines of a variety of different heights, not only waste big
The money of amount, and use and its inconvenience, be not suitable for promoting the use of.
At present, it is necessary to use substantial amounts of petroleum pipeline in the exploitation of oil and transportation.Petroleum pipeline was being applied
Often multistage petroleum pipeline is linked together uses in journey, need to be defeated by petroleum pipeline long range after the completion of oil exploitation
Various regions are delivered to, because landform or transport need, bend pipe structure is often used in transportation, but on the ground of pipeline bending
Side, impulsive force suffered by pipeline is bigger, and the damage to pipeline is larger, gets off for a long time, easily causes petroleum pipeline damage, and to stone
The replacing or maintenance of oil-piping are fairly cumbersome, take time and effort, and cost is higher.
For above-mentioned technical problem, the patent of Application No. 201710248227.1 discloses one kind and is applied to petroleum pipeline
Damping, including fix bar, be provided with spring outside fix bar, one end of spring is fixed on the inwall of petroleum pipeline, separately
One end is provided with sliding sleeve, and sliding sleeve one end is provided with opening and is internally formed a cavity；One end of the fix bar
It is fixed on the inwall of petroleum pipeline, the other end is located in sliding sleeve, and sliding sleeve can move along fix bar；The cunning
The outer wall of moving sleeve is provided with auxiliary buffer board, and the one end of sliding sleeve away from spring is provided with filter, and filter
It can be rotated around the axis direction of sliding sleeve.The spring shock absorption mechanism and auxiliary buffer board that the technical scheme is set can be reduced
Impulsive force suffered by petroleum pipeline bending place, and filter can reduce impurity in oil and waste residue rushes to inner-walls of duct
Hit, labour and maintenance cost are reduced, however, the technical scheme still has following deficiency：1st, filled by the use of spring as damping
Put, with the high speed constant flow of oil, the spring-compressed degree that reaches capacity just is unable to continued compression, so as to only formerly flowing
Oil fraction kinetic energy can be converted into the elastic potential energy of spring, just will not be made in the oil of rear flowing by the damping of spring
With cushioning ability is limited；2nd, during impurity and waste residue of the filter in filtering oil, swiftly flowing oil is continued
The a large amount of waste residues carried are intercepted at filter side, easily cause petroleum pipeline blocking, are unfavorable for the transport of oil, reduce
Conevying efficiency.
The content of the invention
The deficiencies in the prior art in view of the above, it is an object of the invention to provide one kind to be based on petroleum pipeline bending place
The damping device of setting, the sustainable effective impulsive force reduced suffered by petroleum pipeline bending place, avoids oil directly to stone
Oil-piping inwall impacts.
In order to achieve the above objects and other related objects, base case of the present invention is as follows：
A kind of damping device set based on petroleum pipeline bending place, including sliding sleeve, the axial direction of the sliding sleeve
Line is identical with the axial line of petroleum pipeline, and the sliding sleeve is fixedly connected close to oil inflow direction with petroleum pipeline；Also wrap
