Armored bellows are tubular elastic sensors connected along the folding and stretching direction by folding bellows. Bellows are widely used in instruments and meters. The main purpose is to convert pressure into displacement or force as a measuring element of pressure measuring instrument. Armoured bellows have thin walls and high sensitivity, ranging from tens of pascals to tens of megabascals. The open end is fixed, the sealed end is in a free state, and the elasticity is increased by auxiliary helical springs or reeds. When the action is under the action of internal pressure, it extends along the length direction of the pipeline, so that the movable end produces a certain relationship with the pressure displacement. The following is to understand the technical realization of the lower armored bellows.
Armored bellows is a new type of bellows with simple structure, novel design, combined bellows groove structure, which can realize free stretching of bellows, and can fold back after stretching, convenient and practical.
Armored bellows in order to solve the existing problems, using the following technical solutions: including the bellows main body, tensile wave, arc wave groove, tensile corrugated plate; Several tensile waves are arranged on the surface of the main body of the wave tube. The extended wave groove is composed of a pair of circular wave grooves and an extended concave wave plate. The extended concave wave plate is connected between the left and right circular wave grooves.
Armored bellows are preferred; Although the arc-shaped wave groove, extended corrugated plate and the main body of the wave tube are integrated structures, the beneficial effects are as follows: simple structure, novel design, combined wave groove structure, free extension of the bellows, after extension can be retractable, convenient and practical.
Technical realization of armored bellows
Armoured bellows include: bellows subject, elongation, arc wave trough, wave elongation invagination corrugated plate, the surface of the wave tube body set up several tensile wave, extension wave trough extension from a pair of circular arc wave trough and invagination of wave plate, connection between about arc wave trough has extended invagination wave plate, armoured bellows its characteristics is arc shape wave trough, extending invagination wave plate and wave tube structure of main body is an organic whole.
Armored bellows relates to the technical field of connecting pipelines, in particular to a new type of bellows. Including wave tube body, stretching, arc wave trough, stretching invagination wave plate, the surface of the wave tube body set up several tensile wave, stretch wave trough extension from a pair of circular arc wave trough and invagination of wave plate, connection between about arc wave trough has extended invagination wave plate, simple structure, novel design, using combined bellows structure, can realize the freedom of the bellows stretching, And after stretching can fold back, convenient and practical.
