Description

High-strength prestressed corrugated pipe mud jacking exhaust device

Technical Field

The utility model belongs to plastics bellows processing field, concretely relates to prestressing force bellows mud jacking exhaust apparatus excels in.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application 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 thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction 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 are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.

The plastic corrugated pipe also has a large amount of applications in the building industry, and the bellows adopts extrusion process to produce, but when the bellows carries out the mud jacking and uses, the pressure that inside unnecessary gas produced need be discharged, this just needs trompil row pressure on the bellows, and current row pressure all adopts the mode of direct trompil on the bellows to go on, and it is comparatively fragile around the local trompil that needs row pressure makes the bellows trompil department easily, is unfavorable for subsequent exhaust operation, causes the fracture of bellows easily.
