The gauze pad structure is the same, coordination is coincident, protrusions and sunken parts are matched to enable independent gauze pads to be combined in an interaction mode, rotation is prevented, material joining is strengthened, and the whole structure strength is guaranteed. Gaps necessarily exist between matched parts, axial deformation can be absorbed through the gaps, meanwhile, the gauze pads can be increased or decreased according to actual conditions and can be produced in mass, the gauze pad body structure can accordingly and effectively serve as the gauze pad structure for absorbing stress, and the gauze pad body structure can also be used in cooperation with other devices for use.
Description
Technical field
The utility model relates to a kind of gauze pad body structure, belongs to thermal stress compensation device technical field.
Background technique
In order to reduce the thermal stress of pipeline, generally between pipeline, install compensator, or utilize the bending of pipeline itself with auto-compensation.In the configuration of pipeline, should pay the utmost attention to the natural compensating action that utilizes pipe bending, this automatic compensating that utilizes pipeline self length change is best bet, in the time that natural compensation can not meet the demands, compensator can be set.Specifically have: (1) filler compensator: material filling type compensator claims again pipe-type compensator, it can be divided into two kinds of cast iron and steels.The working principle of filler compensator is in the time that pipeline expands with heat and contract with cold, and large small sleeve relatively moves to absorb its expansion length.Between filler and sleeve, because friction produces reaction thrust, its size is directly proportional to manifold pressure, and irrelevant with the amount of deformation of pipeline.When installation, the size of material filling type compensator is overlapped simple two ends respectively a fulcrum, and one fixing, a slip.The advantage of this compensator is that floor space is little, installs simply, and fluid resistance is little, and wall thickness is corrosion-resistant, has larger compensation ability.Its shortcoming is that cost is higher, makes comparatively difficulty, easily leaks, leaks gas, and it is applicable to, and the temperature difference is large, internal pressure is low and the antileakaging pipeline of medium, in normal pressure gas pipeline, often adopts.(2) auto-compensation of pipeline it be to utilize natural torsion in pipe laying to carry out the thermal stretching distortion of extraction duct, common are L shaped or z shape.L shaped and z shape compensator (claiming again nature compensator) can utilize ducted elbow to form, and is convenient to install.In pipeline construction, should make full use of these two kinds of compensators and do the compensation of thermal expansion, and then consider to adopt the compensator of other kind.The advantage of auto-compensation is can less space of compensation device, produces lateral displacement when shortcoming is pipe deforming.(3) drum shape metal compensator: drum type compensator is installed simple, and fluid resistance is little, but compensation ability is little, intensity a little less than, be generally used for diameter large, low pressure and be afraid of the medium leaking, conventional in blast furnace gas is carried.Drum type compensator advantage is to make to be easier to, and investment economizes; Shortcoming is that corrosion resistance is bad.Based on above-mentioned technical deficiency, the utility model adopts another gauze pad body to reduce thermal stress just.
Summary of the invention
The purpose of this utility model is to provide a kind of gauze pad body structure, to can utilize better this gauze pad to be arranged in pipeline, and in order to eliminate pipeline pressure, the release of convenient pipeline thermal stress.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of gauze pad body structure, comprises gauze pad inner ring, gauze pad outer ring and gauze pad connecting body, wherein, between gauze pad inner ring and gauze pad outer ring, is provided with gauze pad connecting body, is provided with convex body in gauze pad connecting body, and convex body interconnects, and is combined to form gauze pad formula cavity; Gauze pad inner ring, gauze pad outer ring cross section are profile of tooth, middle hollow out.
Further, gauze pad connecting body is connected with gauze pad outer ring radial arrays along gauze pad inner ring.
Further, between gauze pad connecting body and gauze pad connecting body, be provided with space, become hollow out body.
In the utility model, hollow out is regular, be convenient to assembling, spatial structure has formed special hollow out effect cleverly, these structures are used for guiding strain, improve material internal stress, other materials is filled in order to make up the defect of homogenous material performance in space, final formation axially and radially compensation simultaneously but can not deformation failure.
These device radial design main points, the hollow out of bending character, has formed stressed tender spots, will first be out of shape to compensate inner core while there is radially deformation herein.The another side of excision material has projection, and material is even everywhere can to guarantee gauze pad, and structural strength is uniformly distributed.This structure mainly absorbs radial deformation.Periphery design main points: each structure forms array on circumference, and material and performance have symmetry properties.The hollow out at interval is used for filling other excellent materials.Along with radius increases, structure is corresponding reinforcement also, and dimensional deformation is than inner few.Distortion can be limited in like this to compensator inside.Axial design main points: gauze pad structure is identical, coordinate unanimously, and projection and depression match and make independently gauze pad form mutual fusion, prevent rotation, and the linking of reinforcing material guarantees overall construction intensity.Its cooperation certainly exists gap, and these gaps can be used to absorb axial deformation, meanwhile, can increase and decrease gauze pad according to actual conditions, and gauze pad also can be produced in batches.
The beneficial effect of this model utility is: the utility model adopts the hollow out of bending character, has formed stressed tender spots, will first be out of shape to compensate inner core while there is radially deformation herein.The another side of excision material has projection, and material is even everywhere can to guarantee gauze pad, and structural strength is uniformly distributed.Gauze pad structure is identical, coordinates unanimously, and projection and depression match and make independently gauze pad form mutual fusion, prevent rotation, and the linking of reinforcing material guarantees overall construction intensity.Its cooperation certainly exists gap, and these gaps can be used to absorb axial deformation, simultaneously, can increase and decrease gauze pad according to actual conditions, gauze pad also can be produced in batches, thereby can be effective as the gauze pad structure use that absorbs stress, also can coordinate other devices to use.
