Description
Technical field
This utility model belongs to sealing member technical field, is specifically related to a kind of rubber bellows.
Background technology
Corrugated tube class component is widely used in hydraulic system, and during work, inner chamber is filled with gas or liquid medium, and has one
Fixed pressure, it is therefore necessary to ensure sealing, when designing sealing system, it is necessary to according to the operating pressure of system, ambient temperature,
The factors such as mixture condition, select suitable sealing member, general corrugated tube mostly to be metal bellows, and its cost is higher, hardness
Can not regulate and control, and for some sealing medium, such as liquid such as acid, alkali inapplicable, it is therefore desirable to exploitation a kind of corrosion resistance, warp
The most durable corrugated tube with good sealing effect.
Utility model content
This utility model overcomes the shortcoming that existing corrugated tube exists, it is provided that a kind of rubber bellows, this corrugated tube profit
By the high resiliency of rubber, high-air-tightness, resistance to medium, weatherability and radiation resistance, hardness can regulate and control, can apply to acid,
Alkali occasion, and cost is relatively low.
Concrete technical scheme of the present utility model is:
A kind of rubber bellows, this corrugated tube includes the elastic pressure-bearing pipe that tube wall is meander-shaped, and key point is, described
The tube wall of elastic pressure-bearing pipe is broken line shape, and described elastic pressure-bearing pipe two ends are provided with the union joint of annular, union joint
It is provided with for clamping element being carried out spacing clamping platform with outside the link position of elastic pressure-bearing pipe.
The minimum diameter of described elastic pressure-bearing pipe is not less than the internal diameter of union joint.
The wall thickness of described elastic pressure-bearing pipe is not less than 1.5mm.
The draw ratio of described rubber bellows is not more than 3:1.
The beneficial effects of the utility model are: in this utility model, corrugated tube uses quality of rubber materials, and two ends are by even
Joint is fixedly connected, and the clamping platform on union joint is that clamping element provides restraining position, connects the most reliable, it is possible to anti-
Only the coming off of rubber when under high pressure corrugated tube, connected mode is the most more convenient, the performance of rubber bellows is relatively stable and cost relatively
Low, corrosion damage will not occur, it is possible to be applied to the corrosive situations such as soda acid, and hardness can be by different rubber raw materials
Being adjusted, bearing capacity also is able to be changed therewith, and durable in use, sealing effectiveness is preferable.
Accompanying drawing explanation
Fig. 1 is the structural representation of rubber bellows in this utility model.
In accompanying drawing, 1, elastic pressure-bearing pipe, 2, union joint, 3, clamping platform.
Detailed description of the invention
This utility model relates to a kind of rubber bellows, and this corrugated tube includes the elastic pressure-bearing pipe 1 that tube wall is meander-shaped,
The tube wall of described elastic pressure-bearing pipe 1 is broken line shape, and described elastic pressure-bearing pipe 1 two ends are provided with the union joint of annular
2, union joint 2 is structure as a whole with elastic pressure-bearing pipe 1, be provided with outside union joint 2 and the link position of elastic pressure-bearing pipe 1 for
Clamping element is carried out spacing clamping platform 3.
Specific embodiment, this rubber bellows can be played along longitudinal extension by rubber tubular structure made by molding, tube wall
Buffering and buffer action, can be regulated the complexity of rubber deformation, thus adapt to different pressures by the hardness changing rubber
Force environment, it is possible to the material changing rubber raw materials adapts to the work condition environment of different medium and different temperatures.
During use, as it is shown in figure 1, by union joint 2 internal diameter and relevant device or outer diameter tube assembly connection, at clamping platform 3
Place carries out card by metal clip and fastens, and metal clip is fixed on inside clamping platform 3, and the clamping platform 3 at two ends makes union joint 2
And between relevant device or pipeline, possessing certain clamping force, the minimum diameter of elastic pressure-bearing pipe 1 is not less than the interior of union joint 2
Footpath, gas or liquid through union joint 2 internal diameter will not be stopped in original direction of advance, and flowing velocity does not have bright
Aobvious reduction, the wall thickness of elastic pressure-bearing pipe 1 is 1.5mm, a length of 57mm, and the internal diameter of union joint 2 is 12.75mm, and thickness is 2mm,
The external diameter of union joint 2 is 21.6mm, and the external diameter of elastic pressure-bearing pipe 1 is identical with the external diameter of union joint 2, the draw ratio of rubber bellows
Being not more than 3:1, the setting of draw ratio is it can be avoided that the weakened that causes time long of rubber corrugated length of tube, it is ensured that corrugated tube
Moderate strength.
In this utility model, rubber bellows is durable in use, and quality of rubber materials compactness is good, be difficult to reveal medium, compressibility and
Resilience is good, and permanent deformation is little, and corrosion resistance is good, different glue kinds can be selected to fit according to the difference of sealing medium
Should, the simple in construction of rubber bellows, convenient processing and manufacture, cost is relatively low, and the wearability after fixing is good, it is ensured that corrugated tube
Sealing property, work for a long time in the media such as acid, alkali, oil, its volume and firmness change are little, and are not adhere to metal surface
On.
