Description

Anti-disengaging double-seal socket mechanism

Technical Field

The utility model relates to the technical field of corrugated pipes, in particular to a release-stopping double-seal socket mechanism.

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.

The bellows mainly comprises a pipe body, a bellows body wound on the outer side wall of the circumference of the pipe body, a bell mouth and a spigot, wherein the spigot is inserted into the bell mouth during pipe connection, a sealing ring is arranged between the bell mouth and the spigot, the pipe body is connected through the bell mouth and the spigot, the bell mouth and the spigot are sealed by the sealing ring, the sealing effect between two adjacent pipe bodies is guaranteed, the existing bell mouth and spigot are straight pipes, a sealing ring groove is arranged on the spigot, the sealing ring is arranged in the sealing ring groove, the sealing ring is contacted with the inner cavity side wall of the bell mouth when the spigot is inserted into the inside of the bell mouth, the sealing effect between the bell mouth and the spigot is guaranteed by the sealing ring, however, the sealing ring has service life, and the sealing ring can be damaged when the service life of the sealing ring is prolonged, so that the sealing effect between the bell mouth and the spigot is greatly influenced.
