Abstract
The invention relates to the field of expansion joints and particularly relates to an expansion joint. The expansion joint comprises a corrugated pipe, connection pipes, ring sleeves, a left flow guide pipe, a right flow guide pipe and a plurality of washing pipes, wherein both the left and the right end of the corrugated pipe are connected with connection pipes; the connection pipes sleeve the outer walls of flow guide pipe flange sides and are connected with the outer walls of the flow guide pipe flange sides in a sealing manner; the ring sleeves are connected with the outer walls of the connection pipes in a sealing manner; two end sides of the corrugated pipe are connected with the ring sleeves on two sides in a sealing manner; a plurality of pipe plugs are arranged on each connection pipe; one end of each washing pipe is connected with each pipe plug, and the other end of the washing pipe faces towards the wave hollow of the corrugated pipe. Through the special structure arrangement, the heat in the expansion joint of the corrugated pipe can be quickly circulated and dissipated, so that the temperature resistance of the expansion joint is improved; meanwhile, a washing pipe is connected inwith the corrugated pipe, so that the interior of the pipe can be washed cleanly; the corrosion of small dirt to the expansion joint is reduced; the service life of the expansion joint is prolonged.
Description
Technical field
The present invention relates to expansion joint field, particularly relate to a kind of expansion joint.
Background technique
Expansion joint is the additional stress compensated 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, the advantages such as reliable operation, functional, compact structure, have been widely used in the departments such as chemical industry, metallurgy, nuclear energy.Expansion joint is divided into bent-tube boiler expansion joint, bellows expansion joint etc., bellows-type expansion is energy-conservation flexible along pipeline axial direction, also allow a small amount of bending, it is not bery high that it is generally used for temperature and pressure, on the pipeline that length is shorter, and the life-span is shorter, significantly limit the use of bellows-type expansion joint, as many thickness of convolution wall unitary moulding corrugated-type expansion joint that China Patent No. is CN2864303, its technological scheme is: it is made up of integrally formed bellows, body is provided with the longitudinal seam that integral forming process is welded into, the thickness range of tube wall is 3-50mm, its benefit is: expansion joint only exists longitudinal seam, and there is no circumferential weld, reduce manufacture cost, improve quality of product, but it is weak that the program does not solve expansion tube heat-resisting quantity, the drawback that life-span is short.
Summary of the invention
The object of the present invention is to provide the expansion joint that a kind of heat-resisting quantity is strong, the life-span is long, to solve multinomial defect of the prior art.
The technological scheme of technical solution problem of the present invention is: a kind of expansion joint, comprise bellows, adapter, ring set, left honeycomb duct, right honeycomb duct and some cleaning hoses, described left honeycomb duct, right honeycomb duct and cleaning hose are all positioned at the inside of bellows, described adapter and left honeycomb duct, right honeycomb duct is all straight-through pipes that one end is provided with flange edge, two ends, described bellows left and right are all connected with adapter, described adapter is sleeved on honeycomb duct flange edge outer wall and is also tightly connected, described ring set is sealedly connected on adapter outer wall, limit, described bellows two ends is tightly connected with the ring set of both sides respectively, described adapter is provided with some plugs, described cleaning hose one end is connected with plug, another rectifies the trough to bellows, during use, left honeycomb duct, right honeycomb duct and the common conducting bellows inner chamber of adapter, make heat can better Quick diffusing, cleaning hose can be connected after expansion joint uses, the materials such as the solid crystal condensed in bellows trough are rinsed by cleaning hose.
Preferably, described cleaning hose extend into angle between part in trough and vertical direction is 0-5 °.
Preferably, described bellows outside is provided with stainless steel net.
Preferably, described left honeycomb duct internal diameter is more bigger than right honeycomb duct external diameter, and both have one end of flange edge to make coaxial fit outwardly.
Preferably, described bellows is specially individual layer, bilayer or multi-layer structure.
In employing, the beneficial effect of technological scheme is: a kind of expansion joint in the present invention, it is by special vibrational power flow, heat in bellows expansion joint can be circulated faster distribute, thus improve the temperature tolerance of expansion joint, meanwhile, in bellows, access cleaning hose, can rinse well in pipe after a procedure, reduce dirt to the corrosion of expansion joint, increase the service life.It is 0-5 ° that cleaning hose extend into angle between part in trough and vertical direction, better the crystallization on bellows inwall can be rinsed well, bellows outside is provided with stainless steel net, reduce the wearing and tearing of bellows outside, increase the service life, left honeycomb duct internal diameter is more bigger than right honeycomb duct external diameter, both have one end of flange edge to make coaxial fit outwardly, both utilizations superposition section matching gap conducting bellows inner chamber, its internal heat can be circulated faster distribute, bellows can adopt individual layer as required, double-deck, or multi-layer structure, the thickness of bellows can be selected according to service wear degree and sensitivity level.
Accompanying drawing explanation
