Description
Technical field
The present invention relates to new material technology field, steel band reinforced polyethylene spiral ripple pipe is used in specially a kind of buried draining
And attaching method thereof.
Background technique
Bellows refers to the tubular elastomeric sensing element connected into foldable wrinkle piece along folding retractable direction.Bellows
Be widely used in instrument and meter, be mainly used for the measuring cell as pressure measuring instruments, convert pressure into displacement or
Power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of pas to tens of megapascal.Its open end is fixed, sealed end
Increase elasticity in free state, and using the helical spring of auxiliary or reed.Along pipe under the action of internal pressure when work
Sub- elongated lengthwise makes movable end generation and pressure at the displacement of certain relationship.Movable end drives pointer that can directly indicate
The size of pressure.Bellows, which usually combines with displacement sensor, constitutes output as the pressure sensor of electricity, also uses sometimes
Make isolation element.Since the stretching, extension of bellows requires biggish volume to change, its response speed is lower than Bourdon tube.Ripple
Pipe is suitable for measurement low pressure.
Bellows mainly includes metal bellows, expansion bellow, corrugated tube, diaphragm and diaphragm capsule and metal hose etc..
Metal bellows is mainly used in the effects of compensation pipes thermal deformation, damping, absorption line sedimentation and deformation, is widely used in stone

Or power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of pas to tens of megapascal.In addition, bellows can also be used
Make seal isolation element, the measurement part that two media is separated or prevents harmful fluids from entering equipment.It can also be used
Make compensating element, utilizes the temperature error of the changeability compensation apparatus of its volume.It is also sometimes used as the elasticity connection of two parts
Connector etc..Bellows can be divided into two kinds of metal bellows, nonmetallic bellows by constituent material；By structure can be divided into single layer and
Multilayer.Singel-ply bellows is using more.Multilayer corrugated pipe intensity is high, and durability is good, and stress is small, in important measurement.Wave
The material of line pipe is generally bronze, brass, stainless steel, monel metal and inconel that alloy etc..
Metal bellows or other elastic elements is set to generate the rigidity that load value required for unit displacement is known as element, one
As with " K " indicate.If the elastic characteristic of element be it is nonlinear, rigidity is no longer constant, but with the increase of load
It changes.The ripple tubing elastic element of common engineering, rigidity franchise can be limited within +/- 50%.Bellows it is rigid
Degree is different according to load and displacement property, is divided into axial rigidity, bending stiffness, torsion stiffness etc..In the application of bellows, absolutely
Most of stress condition is axial load, and displacement mode is displacement of the lines.
