Description

Automobile corrugated pipe device capable of adapting to different pipe diameters Technical Field The utility model relates to the technical field of automobile accessories, in particular to an automobile corrugated pipe device which can adapt to different pipe diameters. Background The corrugated pipe is a tubular elastic sensing element formed by connecting foldable corrugated sheets along the folding and stretching directions. The bellows is widely used 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 thinner pipe wall and higher sensitivity, and the measuring range is tens of Pa to tens of megaPa. The open end is fixed, the sealed end is in a free state, and the elasticity is increased by using an auxiliary spiral spring or reed. When in operation, the movable end is stretched along the length direction of the pipe 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 often in combination with displacement sensors constitute a pressure sensor that outputs an electrical quantity, sometimes also serving as an isolating element. The bellows has a lower response speed than the bourdon tube because of the large volume change required for expansion. The bellows is adapted to measure low pressure. Flange connection is one of the most common connection modes of corrugated pipes. The flange is fixed with production equipment or a pipeline through bolts, and has the advantages of convenience in disassembly and good sealing performance. The flanges at the two ends of the corrugated pipe are usually flanges with the same specification, and when the corrugated pipe is installed, the plane of the flange is required to be well attached to the outer diameter of the corrugated pipe. The bolts are tightened with uniform torque to avoid damage due to uneven stress. But the current device still has the disadvantage, and current device can not adapt to different pipe diameters when connecting, can't adjust when meetting the pipe diameter of mismatch to current device fixed establishment is not enough, and the during operation takes place to rock easily in the car, fixes through the ribbon, and the ribbon has for a long time become fragile fracture easily, and we propose an automobile bellows device that can adapt to different pipe diameters to solve above-mentioned problem for this reason.
