Abstract
The invention relates to an on-line rubber lining integrality monitoring system. The on-line rubber lining integrality monitoring system is mounted in a plurality of pipes which are connected by flanges; rubber linings are mounted on the inner walls of the pipes; and the on-line rubber lining integrality monitoring system comprises a plurality of first sensors which are embedded in the rubber linings and are arrayed in the direction of the axes of the pipes and a plurality of second sensors which are mounted among the flanges and extend into the pipes. The first sensors which are arrayed in the direction of the axes of the pipes are arranged in the rubber linings, the second sensors which extend into the pipes are mounted among the flanges, rubber lining integrality is monitored by the first sensors, rubber lining ageing states are monitored by the second sensors, so that the rubber linings can be monitored in an on-line manner on two dimensions, the ageing state and the integrity state of the pipes with the rubber linings are acquired, and repairing of the pipes with the rubber linings can be finished in the period of heavy repair, so that the operation and maintenance costs of a power plant are reduced.
Description
Technical field
The invention belongs to pipe testing apparatus field, be specifically related to a kind of line with rubber integrity on-line monitoring system.
Background technology
Rubber lining (i.e. line with rubber) because of have good corrosion resistance, reliability, machinability and can toolability, in the environment that nuclear power plant environment temperature the highest (< 85 DEG C), corrosive medium are the strongest, (briny environment and acid-alkali salt environment) is widely used.Rubber lining as other material, under arms during be faced with ageing failure problem.Line with rubber ageing failure phenomenon once occurs, the most rubber lined be full of cracks and coming off, by making sea water or the stronger medium of acid-alkali salt corrosivity directly contact with metallic matrix through rubber lining, cause metallic matrix to corrode rapidly, the event such as corrosion failure, leakage even occurs.Additionally, rubber lining is aged to a certain degree, the phenomenon that large area comes off easily occurs, and the line with rubber layer come off is it is also possible to block the equipment such as pipeline, valve, pump, filter and heat exchanger, cause the disabler of these equipment, and the inefficacy of these equipment can bring a series of safety problem.
In prior art, rubber lined inefficacy checks that first-selection is visual examination, checks whether line with rubber has rusty stain, bubbling, problems of crack, and visual examination is mainly by visual inspection, when naked eyes are inconvenient to check, and can be by instruments such as photographing unit, illuminator and endoscopies.If it find that during those suspected defects, need to make further to judge by percussion hammer, electric spark；Percussion hammer is mainly checking hard rubber, when finding doubtful bubbling but not can determine that, raps with percussion hammer, judges whether bubbling according to sound；Electric spark inspection is used in when not can determine that defect is the most damaged, and electricity consumption Spark plug optical fiber sensor is verified further.On the whole, when detecting line with rubber breakage, it is presently mainly daily maintainability detection both at home and abroad；In view of the aging serious consequence being likely to occur occur in importance and the line with rubber of rubber lining equipment later, it is badly in need of the real time on-line monitoring system of more system of developing.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art to provide a kind of line with rubber integrity on-line monitoring system.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is: a kind of line with rubber integrity on-line monitoring system, it is arranged on by many pipelines of Flange joint, described inner-walls of duct is provided with line with rubber, the multiple tracks first sensor arranged in it includes being embedded at described line with rubber and along described pipeline direction of axis line and the second sensor being arranged between described flange and extending in described pipeline.
Optimally, described first sensor is ringwise.
Optimally, first sensor spaced set described in multiple tracks is on described line with rubber.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that line with rubber integrity on-line monitoring system of the present invention, by arranging the multiple tracks first sensor along the arrangement of pipeline direction of axis line in line with rubber, and the second sensor extending in pipeline is installed between the flanges, realize the monitoring to line with rubber integrity by first sensor and realize the monitoring to line with rubber ageing state by the second sensor, so can realize the on-line monitoring to it in two dimensions, obtain ageing state and the integrity state of rubber lined pipe, be conducive to during overhaul, complete rubber lined pipe maintenance, thus reduce power plant's O&M cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is described in detail.
Line with rubber integrity on-line monitoring system as depicted in figs. 1 and 2, mainly includes first sensor 4 and the second sensor 5.
Wherein, this line with rubber integrity on-line monitoring system is typically mounted on the industries such as electric power, chemical industry, nuclear power station and exists in the pipeline 1 that corrosion is possible, many pipelines 1 form tubing by being arranged on the flange 2 of its end and being attached, and line with rubber 3 is then corresponding to be arranged on the inwall of these pipelines 1.First sensor 4 has multiple tracks, and they are embedded in line with rubber 3, and arranges successively along the direction of axis line of pipeline 1；They are line with rubber Integrity Verification sensor, for monitoring the integrity of line with rubber.Second sensor 5 also has multiple, and each of which is arranged between two flanges 2, and extends in pipeline 1；They are line with rubber ageing state monitoring sensor (the most forced corrosion monitoring sensor), for monitoring the line with rubber ageing state of line with rubber, whether there is, in the fluid in such as monitoring pipeline 1, the line with rubber come off.When actually used, first sensor 4 and the second sensor 5 can be attached with control module or signal acquisition module respectively, thus the signal producing it is acquired and analyzes.The line with rubber integrity on-line monitoring system of this spline structure is applicable to project sites and installs, and can obtain line with rubber ageing state and integrity information thereof in real time.In the present embodiment, first sensor 4 is the loop configuration corresponding with line with rubber 3, and they are set in qually spaced on line with rubber 3.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
