Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a riveted corrugated pipe. Background Technique

[0002] A corrugated pipe refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and telescoping direction; corrugated pipes are widely used in construction, factory production, and instruments. Their main purpose is to be used as a measuring element for pressure measuring instruments, which is elastic and can convert pressure into displacement or force; the wall of the corrugated pipe is relatively thin, with high sensitivity, and the measurement range is from dozens of pascals to dozens of megapascals. Its open end is fixed, and the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity; when working, under the action of internal pressure, it elongates along the length direction of the pipe, causing the movable end to generate a displacement related to the pressure. It is often combined with a displacement sensor to form a pressure sensor with an electrical output, and sometimes it is also used as an isolation element; since the expansion of the corrugated pipe requires a large volume change, its response speed is lower than that of a Bourdon tube; when the corrugated pipe is in use, the length of the corrugated pipe is not enough, and the corrugated pipe needs to be connected; currently, the existing corrugated pipes are connected by bolts. When the object inside the corrugated pipe flows, the corrugated pipe will shake. Long-term shaking will cause the bolts to loosen, resulting in unstable connection and weak strength of the corrugated pipe; therefore, a riveted corrugated pipe is proposed to solve the above problems.
