Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
This utility model embodiment provides a kind of setting rubber pneumatic bag of inflated type, as shown in Figure 1, the enhancing termination 2 that the two ends of cartridge type main body 1 and cartridge type main body 1 that the setting rubber pneumatic bag of this inflated type includes both ends open are tightly connected, and at least one strengthens the inflatable interface 3 being provided with the intracavity inter-connection with cartridge type main body 1 on termination 2.Cartridge type main body 1 includes the one-body molded high rigidity cylindrical shape rubber layer 101 prepared, and is provided with at least one low-hardness rubber flange collar 102, and the elasticity of rubber flange collar 102 is higher than the elasticity of cylindrical shape rubber layer 101 on the outer surface of cylindrical shape rubber layer 101；Strengthen termination 2 and include from the inside to the outside close-connected inner rubber layer 201, cloth skeleton enhancement layer 202 and outer rubber layer 203 successively.
The setting rubber pneumatic bag of inflated type that this utility model embodiment provides, by the outer surface at the cylindrical shape rubber layer 101 of high rigidity arranging the rubber flange collar 102 of multiple soft as cartridge type main body 1, prepare owing to cylindrical shape rubber layer 101 is one-body molded, and hardness is high and elastic low, there is pressure-bearing effect more preferably and crocking resistance, and the low and elastic height of rubber flange collar 102 hardness, it is more conducive to be in close contact with inner-walls of duct after inflation, reaches good sealing.Additionally, arrange the enhancing termination 2 that cloth skeleton strengthens at the two ends of cartridge type main body 1 so that it is there is certain rigidity, effectively prevent the inflatable interface 3 being located thereon from coming off.Visible, the setting rubber pneumatic bag of inflated type that this utility model embodiment provides is honored as a queen in pipeline inner seat, not only has bearing capacity more preferably and has good sealing, its simple in construction, it is simple to make, it is simple to large-scale promotion is applied.
For example, the high rigidity cylindrical shape rubber layer 101 described in this utility model embodiment, its hardness is it suffices that its i.e. inflatable but also can bear the pressure of 2-3MPa, and in general, the hardness range of this high rigidity cylindrical shape rubber layer 101 is shore 70 °-80 °.And the low-hardness rubber flange collar 102 that this utility model embodiment provides, its hardness lower than the hardness of cylindrical shape rubber layer 101, and should can guarantee that it has certain elasticity, and in general, the hardness range of this low-hardness rubber flange collar 102 is shore 45 °-65 °.
In order to ensure the bearing capacity of the setting rubber pneumatic bag of this inflated type, and ensureing its lightweight, the thickness of this cylindrical shape rubber layer 101 is 5-15mm, for instance for 7mm, 9mm, 10mm, 12mm, 14mm etc..
Specifically, it is to be understood that all rounded structure of each rubber flange collar 102, the radial direction along cylindrical shape rubber layer 101 is closely set with on its external wall.As shown in Figure 1, at least one rubber flange collar 102 being axially intervally installed along cylindrical shape rubber layer 101, it is separated with predetermined distance between namely between two cylindrical shape rubber layers 101 of arbitrary neighborhood.Wherein, one sidewall of multiple rubber flange collars 102 is embedded in cylindrical shape rubber layer 101, another sidewall externally protrudes out in cylindrical shape rubber layer 101 surface, and the height of multiple rubber flange collar 102 part of externally protruding out in cylindrical shape rubber layer 101 surface is 3-6mm, for instance for 3mm, 4mm, 5mm, 6mm etc..For example, can arrange multiple along cylindrical shape rubber layer 101 radially uniform, such as 6-12 groove, one sidewall of the rubber flange collar 102 of respective number is fixed in this groove, another sidewall externally protrudes out in cylindrical shape rubber layer 101 surface, so, the first circle configurations being made up of rubber flange collar 102 can be formed at the outer surface of cylindrical shape rubber layer 101, further, axial along cylindrical shape rubber layer 101, form the second circle configurations being made up of rubber flange collar 102 on its outer surface, 3rd circle configurations, 4th circle configurations, 5th circle configurations or more, the sealing being greatly enhanced between the setting rubber pneumatic bag of this inflated type and inner-walls of duct is so set.
It is understood that for the consistent and smooth inner-walls of duct of internal diameter, in order to ensure sealing, in the setting rubber pneumatic bag of this inflated type, multiple rubber flange collars 102 externally protrude out in the highly preferred for identical of the part on cylindrical shape rubber layer 101 surface；And internal diameter is changed or coarse inner-walls of duct, it is also possible to the height of the part that multiple rubber flange collars 102 are externally protruded out in cylindrical shape rubber layer 101 surface is set as differing, with the specific inner-walls of duct of correspondence.
Further, each rubber flange collar 102 width on the axial direction of cylindrical shape rubber layer 101 is 5-8mm, for instance for 5mm, 6mm, 7mm, 8mm etc., to improve this rubber pneumatic bag sealing when setting and between inner-walls of duct.
Specifically, this utility model embodiment is arranged to by the enhancing composite construction that close-connected inner rubber layer 201, cloth skeleton enhancement layer 202 and outer rubber layer 203 are constituted successively from the inside to the outside by strengthening termination 2, to improve the rigidity strengthening termination 2.It is understandable that, the rubber that in enhancing termination 2, inner rubber layer 201 used and outer rubber layer 203 all can be commonly used for prior art inflatable airbag, its hardness is generally shore 85 °-95 °, the cloth skeleton enhancement layer 202 used can select enhanced fabrics, such as wherein can contain diameter is the thermoplastic resin fibre of 100-1000nm, and this enhanced fabrics can be plain cloth, twills etc..
Further, for the ease of being tightly connected with the two ends of cartridge type main body 1, this utility model embodiment will strengthen the curved covering plate structure in termination 2, and the opening strengthening termination 2 is bonded in the opening of cylindrical shape rubber layer 101.Further, in order to ensure to strengthen rigidity and the intensity of termination 2, the thickness strengthening termination 2 is 15-20mm, for instance for 15mm, 16mm, 17mm, 18mm, 19mm, 20mm etc..
Further, this utility model embodiment is provided with multiple draw ring 4 at least one enhancing termination 2, it is preferable that the number of draw ring 4 is even numbers, every 2 draw rings 4 are symmetrical arranged along the axis strengthening termination 2, are so arranged as in being placed by setting for this inflated type rubber pneumatic bag or pull-out pipeline.
The foregoing is only preferred embodiment of the present utility model; not in order to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
