Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe assemblies, in particular to an engine corrugated pipe assembly. Background Art

[0002] A bellows is a tubular elastic sensitive element constructed by connecting foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls and high sensitivity, with a measurement range from tens of Pa to tens of MPa. The open end is fixed, while the sealed end is free, and an auxiliary coil spring or reed is used to increase its elasticity. During operation, the bellows stretches along the length of the tube under the influence of internal pressure, causing the movable end to move in a manner proportional to the pressure. This movable end drives a pointer, directly indicating the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output electrical quantities, and are sometimes also used as isolation elements.

[0003] In the existing technology, when installing and using, engine bellows are connected and installed using clamps, flanges and connecting caps. Engine bellows with different connection methods are selected according to different engine needs, which has poor applicability. In addition, most engine bellows are made of a single material such as metal or nylon. During use, they are affected by external factors, and their corrosion resistance and wear resistance are low, which indirectly affects their service life.

[0004] Therefore, an engine bellows pipeline assembly is proposed to solve the above problems. Utility Model Content
