Description
Technical field
The utility model relates to compensator technical field, is specifically related to a kind of wear-resisting high compensation rate three-dimensional coal dust compensator.
Background technique
Compensator is of many uses in modern industry, and compensator is also expansion joint 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.Belong to a kind of compensating element.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 for noise-and-vibration-reduction.In heat supply, when heating up to prevent heat supply pipeline, causing pipe deforming or destruction due to thermal stretching or temperature stress, needing 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.
Compensator has following effect:
1. compensate extraction duct axis, transverse direction, the cold and hot distortion of angle.
2. FlexbleJoint extending amount, facilitates the installation and removal of valve pipe.
3. absorption equipment vibration, reduces vibration equipment to the impact of pipeline.
4. absorb earthquake, earth subsidence to the amount of deformation of pipeline.
Because the restriction being subject to each side is quite complicated, but the piping of any complexity can select several fixed supports to select different settings at different positions, be divided into the relatively simple pipeline section separately of some shapes, " Z " type pipeline section and " ∏ " type pipeline section etc., and determine distortion and the compensation rate of each pipeline section respectively, because the kind of compensator is a lot, correctly type selecting is very important, therefore when the general arrangement of piping, should consider that the trend of pipeline and support system (comprise fixed pipe support fully, guiding slip pipe support etc.) design and consider moulding and the configuration of compensator, safety is reached to show, rationally, be suitable for, economic best of breed.Corrugated expansion joint it be take bellows as the flexible element of core, pipeline remakes the compensation in axis, transverse direction and angle three directions.Axialmode compensator is in order to reduce the self-excitation phenomena of medium.Inner sleeve is not had at interiors of products, greatly limit radial compensation ability, therefore it is general only in order to absorb or to compensate the axial displacement of pipeline (if really need a small amount of radial displacement in piping, its footpath maximum displacement is explained when can order goods): lateral displacement compensator (large pull bar) dominant absorption is perpendicular to the lateral displacement of compensator axis, lower link bar lateral displacement compensator is suitable for absorbing lateral displacement, also can absorption axes to the combination of, angle and any three direction displacements: hinge compensator (also claiming angular compensator).It supports the use (used aloned hinge compensator does not have compensation ability) with two or three compensators, in order to absorb the lateral deformation in one-way planar, universal coupling (angle) compensator, is supported the use by two or three, the amount of deformation of Absorbable rod three-dimensional.
Coal dust three-dimensional compensator is applicable to coal dust, hot blast gas-particle two-phase fluid.
The compensation rate of existing coal dust three-dimensional compensator is certain, so in use, nearer distance just needs arrangement compensator, which not only adds user cost, and damping effect is general, can not get a desired effect.
At present, the working life of coal dust three-dimensional compensator is on the market short, and wear-resisting property is general, generally needs thoroughly to change whole compensator at 3-5, if change not in time, there will be the phenomenons such as leakage.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, reasonable in design, easy to use and the wear-resisting high compensation rate three-dimensional coal dust compensator of long service life.
For achieving the above object, the technical solution adopted in the utility model is: it comprises the first adapter, the second adapter, middle adapter, inner adapter, bellows, ring flat-plate, corrosion-inhibiting coating, wearing layer; Bellows is provided with between two ring flat-plates, the outer wall of bellows is provided with corrosion-inhibiting coating, inner adapter is provided with in bellows, the outer end and first of inner adapter is taken over and is connected, the inner of inner adapter is connected with middle adapter, second adapter is arranged on the outer end of the first adapter, and the inwall of the first adapter, the second adapter, middle adapter is equipped with wearing layer.
As preferably, the first described adapter, the joint of the second adapter are provided with seal arrangement.
As preferably, described wearing layer is the wearing layers of three layers of combination, improves wear-resisting property, increases the service life.
Distance between described two ring flat-plates coordinated is greater than the length of middle adapter, is conducive to improving compensation rate.
During the utility model operation, elongated compared with prior art corrugated pipe segment can improve compensation rate, and interconnective first adapter, the second adapter also can assist the compensation rate increased in operating process outside ring flat-plate, the several layers of wearing layer for all pipe interiors improve the wear-resisting property of compensator greatly.
After adopting said structure, the utility model beneficial effect is: its structure is simple, reasonable in design, easy to operate, the bellows increased and the first adapter and second cooperatively interacted are taken over and are conducive to improving compensation rate, the wearing layer of the stacked conjunction of number improves the wear-resisting property of pipe interior, extends working life.
