Description

Efficient compression-resistant corrugated pipe

Technical Field

The utility model belongs to the technical field of the bellows, concretely relates to bellows of high-efficient resistance to compression.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure. The corrugated pipe mainly comprises a metal corrugated pipe, a corrugated expansion joint, a corrugated heat exchange pipe, a diaphragm capsule, a metal hose and the like. The metal corrugated pipe is mainly applied to the effects of compensating the thermal deformation of a pipeline, damping, absorbing the settlement deformation of the pipeline and the like, and is widely applied to the industries of petrifaction, instruments, aerospace, chemical industry, electric power, cement, metallurgy and the like. The corrugated pipe made of other materials such as plastics has irreplaceable effects in the fields of medium conveying, electric power threading, machine tools, household appliances and the like.

The existing corrugated pipe is often used as a threading pipe in the field of electric power to play a role in protection, but the existing common corrugated pipe does not have a separating function when in use, and cables are wound together and are easy to be confused when in overhaul.
