Abstract
The utility model discloses a pipeline connecting device, in particular to a bush-shaped compensator. The bush-shaped compensator is directly arranged in a pipeline for single-phase or multi-phase pipelines and the bush is connected with the flange via welding; three adjusting screw stems are welded in between the bolt hole and the central hole of the pressing plate; three journals are welded to one end of the core pipe; the snap prevention device composed of a pipe core, a stop block, a circular cushion block and a seal ring are inserted into the bush; the pressing plate and flange are connected and fixed with bolts, a spring pad and fixing nuts, so that the coaxial slide can be ensured without the leakage of medium inside the pipe. This utility model can greatly improve the safety for the operation of the pipeline network and compensate for the coaxial flexibility of the pipeline and coaxial rotation at arbitrary angle. This utility model, which is characterized with small volume and great compensation amount, can be widely applied to the transmission pipelines for industries such as urban heat supply, metallurgy, mining, power generation, petroleum, chemistry and construction, etc.
Description
Technical field
The utility model belongs to assembling pipe joint, particularly a kind of slip-type expansion joint.
Background technique
Existing pipe joint all connects firmly, does not have stretchability, during installation, if the connecting tube cutoff length is improper, can only cut suitable length again, causes waste, or connects by force, and joint is fragile or seal bad.Unless be connected with stretchability with bellows, but because of the ripple tube wall is thin, easy stretched crack causes defect such as leakage, may cause accident to take place, cause any property loss or life safety.
Summary of the invention
The purpose of this utility model provides a kind of slip-type expansion joint, it is characterized in that: sleeve 10 bottoms are welded on the flange 6, the upper end welding of sleeve 10 is ring 11 excessively, the exit takes over 12 again, block 9 is placed on the step of sleeve 10 bottom inner chambers, seal ring 7 slips into sleeve 10 bottoms and is built on the block 9, places cushion block 8 and seal ring 7 again, places a block 9 again on seal ring 7 in 10 mouthfuls in sleeve then; Have and the corresponding screw hole of flange three adjusting screw rods 4 of five equilibrium welding between screw hole and center hole at pressing plate 5 edges; At three journal stirrups 2 of an end of core pipe 11 welding, after tube core 1 passes 5, three adjusting screw rods 4 of pressing plate and pierces into the hole of three journal stirrups 2, to regulate fixingly by nut 3, pressing plate 5 is connected by fixing bolt 13, compression spring 14 and set screw nut 15 with flange 6.
Described cushion block 8 is annulus of diamond-shaped cross-section.
The cross section of described block 9 is that one side is the plane, and one side is the annulus of isosceles triangle.
Described seal ring is the two-sided seal ring that the isoceles triangle groove is arranged.
The beneficial effects of the utility model are that the inner sleeve of sleeve expansion joint is connected with pipeline, adopt the principle and the structure of high-performance self-pressure type motive sealing, and it can adapt to the seal request of any pipeline along with the flexible of pipeline is free to slide in the enclosure.Adopt the novel synthetic material sealing between shell and the inner sleeve, can high temperature resistant, corrosion protection, anti-aging, Applicable temperature-40 in particular cases can reach 350 ℃ ℃ to 150 ℃.Can guarantee to endwisely slip, medium is not revealed in guaranteeing again to manage.
Sleeve expansion joint is provided with anti-breaking device, can guarantee not drawn back when it stretches to limit position, thereby the Security of whole pipe network operation is improved greatly.
Sleeve expansion joint is to the chloride ion content no requirement (NR), is specially adapted in the system that medium or surrounding environment chlorion exceed standard.
