Abstract

The invention discloses application of a flexible high-pressure bag body system with uniform stress. According to the application, a high pressure of 3 to 10 MPa can be provided; single-point or global internal pressure resistance testing of a steel structure and a concrete structure can be realized; and the structure of a flexible high-pressure bag body is manufactured by combining an inner bag and a sleeved reinforcing rib, and a specially-customized flange is matched, so that the pressure of more than ten times higher than that of a common flexible bag body can be borne.

Description

technical field [0001] The invention relates to an application of a flexible high-pressure capsule system, in particular to a flexible capsule capable of withstanding a high pressure of 10 MPa and the application of the system thereof, which can be widely used in the fields of pressure detection, pressure resistance and impact resistance detection, and the like. Background technique [0002] The capsules have many uses. The existing capsules are basically made of thermoplastic materials such as woven cloth coated with polyester and PVC, which are prepared by simple stitching, or are made of sheets prepared by vulcanized rubber technology and then bonded with adhesives. They are prepared by simple stitching technology. The capsules made of these materials are low in strength, easy to leak at the seams, poor in air tightness, and short in working time, while the capsules prepared by the vulcanized rubber process are also low in strength, not pressure-resistant, and poor in safe...
