Bellows bellows means foldable along fold wrinkles sheet stretching direction of the tubular elastic member connected to the sensitive. That its open end is fixed, the seal end in a free state, and the auxiliary coil spring or reed increase flexibility. When working under the action of internal pressure elongated along the longitudinal direction of the tube, the movable end of a displacement of the pressure generating certain relationship. Activities end driven pointer to indicate the size of the direct pressure. Other materials such as corrugated plastic pipe has an irreplaceable role in the medium transport, power threading, machine tools, household appliances and other fields.
