Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe connection, in particular to a sealing structure of a locking corrugated winding reinforced pipe joint device. Background Art

[0002] The corrugated tube refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. The corrugated tube is widely used in instruments and meters. Its main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The corrugated tube has a thinner wall and higher sensitivity. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state. It uses auxiliary spiral springs or reeds to increase elasticity. When working, it stretches along the length of the tube under the action of internal pressure, so that the movable end produces a displacement that is related to the pressure. The movable end drives the pointer to directly indicate the size of the pressure. The corrugated tube is often combined with a displacement sensor to form a pressure sensor with an output of electrical quantity, and is sometimes used as an isolation element. Since the extension of the corrugated tube requires a larger volume change, its response speed is lower than that of the Bourdon tube. The corrugated tube is suitable for measuring low pressure.
