Type, single entry direction type, lateral type, single entry pull rod type, pressure-balancing type, single entry straight-tube pressure-balance,
Composite straight-tube pressure balanced, compound pull rod type, single entry bend pipe pressure balance type, compound relatively chain, list
Formula bend pipe pressure balance type.
For the corrugated stainless steel tubing of common axialmode, corrugated stainless steel tubing is as a kind of flexible pressure-resistant pipe fitting
It is installed in liquid conveying system, in order to compensate pipeline or machine, the mutual displacement of equipment connection end, inhales
Receive vibrational energy, it is possible to play the effect such as vibration damping, noise reduction, have flexible, light weight, corrosion-resistant,
The multinomial feature such as resisting fatigue, high-low temperature resistant.In equipment connects the mutual displacement process of end, due to existing
Corrugated tube without relevant Disturbance Detection equipment, it is impossible to detection corrugated tube use state.
Summary of the invention
It is an object of the invention to provide a kind of based on magnetic row ring disturbance bellows detection device, by
During corrugated tube uses, in corrugated tube perturbation process, drive the first sheath and the second sheath relative movement,
Form cutting magnetic induction line by magnet ring and coil and produce electric current, produced the size of electric current by detection, enter
And detect the speed of corrugated tube forcing frequency, solve existing corrugated tube without relevant Disturbance Detection equipment,
The problems such as the use state that cannot detect corrugated tube.
For solving above-mentioned technical problem, the present invention is achieved by the following technical solutions:
The present invention is a kind of bellows detection device based on magnetic row's ring disturbance, including corrugated tube, first protects
