The invention discloses a kind of flexible high pressure utricule system applications of uniform stress, high pressure 3-10 MPa can be provided, to steel construction, the anti-internal pressure capability test of single-point or the overall situation may be implemented in concrete structure, the structure of flexible high pressure utricule is using the production of the combination of capsula interna and housing reinforcing rib, cooperate special customized flange, ten times of normal flexible utricule or more of pressure can be withstood greater than.
Description
Technical field
The present invention relates to a kind of flexible high pressure utricule system application more particularly to a kind of it is able to bear the soft of 10MPa high pressure
Property utricule and its systematic difference, can be widely used for the fields such as pressure detecting, resistance to compression shock resistance detection.
Background technique
The purposes of utricule is numerous, and existing utricule uses the thermoplastic materials such as woven fabric coating polyester, PVC by simple substantially
Suture is prepared or is bonded after preparing sheet material using vulcanized rubber technique through adhesive, using the preparation of simple sewing process
Utricule intensity is low, and suture is easy gas leakage, and poor air-tightness, the working time is short, and uses the utricule of vulcanized rubber technique preparation same
Sample intensity is low, not withstand pressure, and safety is poor, and thickness is big after vulcanized rubber, not foldable, and storage is difficult, and there is also ageing of rubber
The disadvantages of, it is difficult to be applied to it is high-strength it is high pressure resistant, wear-resistant, air-tightness is excellent, damping, buffering performance is good, it is foldable, using the longevity
The fields such as life length.
Flexible high pressure utricule can be used for investigating the stress and strained situation of structure.Traditional anti-internal pressure test, water-filling can only
It surveys all, part cannot be surveyed, symmetrical press cannot be surveyed, big to local failure according to jack, stress is excessively concentrated, damage
Inner wall.The overall situation can not only be surveyed using flexible high pressure utricule, but also part can be surveyed, binding face consolidation, measurement result is accurate.However it is general
Logical flexible high pressure utricule usually only can provide 0.5 MPa pressure below, and application surface is relatively narrow.
Therefore it needs to prepare a kind of flexible high pressure utricule, and develops the flexible high pressure utricule system of uniform stress, it can
To provide high pressure and be able to maintain good sealing, anti-deformation nature.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of flexible high pressure utricule system application of uniform stress, it can
To provide high pressure 3-10 MPa, to steel construction, the anti-internal pressure capability test of single-point or the overall situation is may be implemented in concrete structure, flexible
The structure of high pressure utricule is cooperated special customized flange, can be born using the production of the combination of capsula interna and housing reinforcing rib
Pressure higher than ten times of normal flexible utricule or more.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of flexible high pressure utricule system application of uniform stress, it is characterised in that: the system is for investigating structure partial or whole
