Abstract
The invention discloses an expansion joint used for a high temperature and high pressure pipeline. The expansion joint comprises an inner casing pipe and an outer casing pipe which can axially move relative to each other. The outer wall of the inner casing pipe is limited by a sliding ring arranged on the inner wall of the outer casing pipe. A gap among the inner casing pipe, the outer casing pipe and the sliding ring forms a sealed area, and the sealed area is sealed by filler. An opening in the side, opposite to the sliding ring, of the sealed area is a filler port. A circle of compression boss matched with the filler port in shape and size is arranged on the outer side of the inner casing pipe. The compression boss and the filler port are each provided with a flange perpendicular to the axial direction. The two flanges are connected through a plurality of sliding rods. The sliding rods and the sliding ring limit the relative movement of the inner casing pipe and the outer casing pipe in the axial direction together. The expansion joint has the beneficial effects that 1, the expansion joint is resistant to corrosion, high temperature and low temperature; 2, through the casing pipe type structural design, the expansion joint is light, small in size and convenient to install; 3, the problem that during long-distance pipeline installation, pipelines expand by heat and contract by cold when temperature changes is solved.
Description
Technical field
The present invention relates to a kind of slip joint, be specially a kind of slip joint for high-temperature and pressure pipeline.
Background technique
Expansion joint is the additional stress for compensating because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Due to it as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.
Expansion joint is also compensator traditionally, or slip joint.By forming the bellows (a kind of elastic element) of its operative body and holding the annexes such as pipe, support, flange, conduit to form.Expansion joint is the additional stress in order to compensate because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Utilize effective dilatation of its operative body bellows, to absorb pipeline, conduit, container etc. by reason and the dimensional changes produced such as expanding with heat and contract with cold, or axial, the transverse direction of compensation pipes, conduit, container etc. and angular displacement.Also can be used in noise-and-vibration-reduction, heat supply, when heating up to prevent heat supply pipeline, pipe deforming or destruction is caused due to thermal stretching or temperature stress, need to arrange compensator on pipeline, to compensate the thermal stretching of pipeline, thus the stress reducing tube wall and the active force acted on valve member or supporting structure.
Due to expansion joint as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that container adopts, has various ways, with regard to the shape of ripple, applies the most extensive with U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint adopted on pipeline is with regard to structure compensation, be divided into again universal, pressure balance type, hinge type and Universal connector hair style etc.But the shortcoming of U-shaped expansion joint be take up room large, consume that steel are many and surface friction drag is large.The shortcoming of bellows expansion joint is that the life-span is shorter, on the pipeline that serviceability temperature and pressure are not bery high, length is shorter.
Summary of the invention
The object of the invention is to provide a kind of slip joint for high-temperature and pressure pipeline, to solve the problems referred to above of prior art.
The object of the invention is to be achieved through the following technical solutions.
For a slip joint for high-temperature and pressure pipeline, comprise the inner sleeve and outer sleeve that can do axial relative movement; The outer wall of described inner sleeve is by being arranged at the slip ring restriction of outer sleeve inner wall; Inner sleeve, formation seal area, space between outer sleeve and slip ring, seal area is by packing seal; A described seal area side opening relative with slip ring is feeding port; At the compression boss that inner sleeve arranged outside has a circle and feeding port shape and size to match; Described compression boss with feeding port is arranged respectively one with axially vertical flange; Connected by some slide bars between two flanges; Described slide bar limits inner sleeve and outer sleeve relative movement in the axial direction together with slip ring.
The gas passed through to keep slip joint, flow quantity are constant, the end interface that described outer sleeve is connected with pipeline, directly go to interface direction and reduce gradually in it; Jointing internal diameter and pipeline, inner sleeve internal diameter are consistent.
The end face that described outer sleeve is connected with pipeline is provided with and axially vertical flange, and the end face that described inner sleeve is connected with pipeline is provided with and axially vertical flange, so that be connected with pipeline.
Described inner sleeve and outer sleeve are carbon steel or A steel; Described seal area is filled to graphite packing.
Beneficial effect of the present invention is:
1, corrosion-resistant, high-low temperature resistant (-50 DEG C ~+420 DEG C);
2, sleeve type structure design, slip joint is lightweight, volume is little, easy for installation.Can as seal element and connecting element in various transfusion, air delivering pipeline system and length, temperature, position and angle compensation system. be widely used in the industries such as oil, chemical industry, metallurgy, electric power, heating, traffic.
3, solve the Pipe installing of long distance, pipeline has the problem of expanding with heat and contract with cold when there being temperature variation, protects pipeline and does not produce destruction when rising-heat contracting-cold to pipeline; And ensure that the gas-liquid of conveying is not revealed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, outer sleeve 2, inner sleeve 3, slip ring 4, seal area 5, feeding port 6, compression boss 7, flange 8, slide bar.
