Description
Technical field
The invention belongs to flange technical fields, and in particular to a kind of flange arrangement available for flange excircle crack monitoring.
Background technology
Flange is connected with the fluid line of water conservancy industry in chemical industry, the connection of the cylinder of the wind-power tower of wind power industry with
And the numerous industrial technical field such as connection between the container of pressure vessel is widely used, be also commonly used for machinery field axis with
Connection between axis, it is important stressed member.In order to obtain preferable intensity, the manufacture of flange generally use metal material, example
Such as carbon steel, stainless steel.
Connecting pin of the flange as two adjacent parts generally requires to bear larger load, these load include pulling force,
Pressure, torsion, shearing force, vibration force etc..Under the effect of improper load, flange is possible to cracked and causes equipment event
Barrier;And under normal applying working condition, flange is also possible to generate fatigue crack due to long-time service, so that flanged joint
It fails and causes equipment breakdown.
In some very important application scenarios, flange is cracked not only to directly contribute equipment fault, and is possible to
The leakage of toxic gas or liquid in pipeline, nuclear power is caused in great security incident, such as such as chemical industry to be followed with cooling
Ring pump causes nuclear power generating equipment stoppage in transit etc. because of flange crack fault.Therefore for the occasion of the highly reliable application of needs, establish flange and split
The monitoring mechanism of line seems very necessary.
The content of the invention
To solve the above-mentioned problems, the detection of flange crackle is realized, the present invention proposes a kind of available for flange excircle crackle
The flange of monitoring, including flange excircle, flanged end face, flange backside face, it is characterised in that opened up on the flange excircle
The annular groove of detection flange crackle is useful for, the inner surface of the annular groove is equipped with non-conductive insulating layer, in the annular groove
Openend be equipped with to close the bottom of the non-conductive ring seal layer of the annular groove, the ring seal layer and annular groove
The toroidal cavity of closing is formed between face and two sides, conductor fluid is perfused in the toroidal cavity, described non-conductive
Leakproofness has passed through plain conductor on ring seal layer, and one end and the conductor fluid of the plain conductor are electrically connected, described
The other end of plain conductor leads to the outside of annular groove by ring seal layer, and the outer of annular groove is led on plain conductor
One section of portion is enclosed with insulating layer.
When flange is in normal condition, state of insulation is kept between plain conductor and the body of metal flange.When outside flange
When circle is cracked, the non-conductive insulating layer in the annular groove on flange excircle is synchronously destroyed, and flange is followed to go out together
Existing crackle, the conductor fluid in annular groove are in contact through non-conductive insulating layer with metal flange body, plain conductor and method
Electrical communication between blue body.Therefore, as long as being linked into the body of plain conductor and metal flange as two terminals
In monitoring system, by the resistance situation for detecting two terminals, you can real-time judge goes out whether flange crackle occurs.
In above-mentioned technical proposal, the ring seal layer includes non-conductive ring spacer and ring packing colloid layer, non-
Conducting loop-shaped partition is covered on conductor fluid, and the ring packing colloid layer is covered on non-conductive ring spacer.
For the ease of installation, ring spacer makes the structure of the annular ring with opening.
Another preferred technical solution of ring seal layer is:The ring seal layer includes non-conductive ring packing
Circle and ring packing colloid layer, the ring type seal is covered on conductor fluid, and forms elasticity with the two sides of annular groove
Contact, the ring packing colloid layer are covered on ring type seal.
Above-mentioned ring seal layer uses the dual-seal result of ring type seal and ring packing colloid layer so that sealing
Reliability is improved by a relatively large margin.
When flange manufactures, first the annular ring with opening or rubber seal are installed in place, then outside is filled out and covered again
One layer of ring packing colloid layer, then conductor fluid is injected by syringe in the toroidal cavity of closing.Ring packing colloid layer
It is preferred that using elasticity or the preferable fluid sealant of extensibility so that have good leakproofness and bullet after ring packing colloid layer desiccation
Property compensation adaptability.
One of preferably, the conductor fluid is freeze proof liquid conducting resinl.
Preferably two, the conductor fluid is the aqueous solution containing conductive ion, and is added in the aqueous solution
Added with antifreeze.
Preferably three, the conductor fluid is mercury.
In the technical program, the non-conductive insulating layer is silicon steel sheet insulating lacquer coat.
But needing the occasion for flange crackle height sensitivity, it is preferable that the non-conductive insulating layer is ceramics
Coating.
Using ceramic coating flange can be caused to be monitored when there is micro-crack.And silicon steel sheet insulating lacquer coat is then applicable in
In the occasion for allowing to ignore some nonlethal micro-cracks and only need to monitor larger fatal crackle.
Preferably, the ring packing colloid layer material is elastic sealant.
The beneficial effects of the invention are as follows:
First, a kind of flange available for flange excircle crack monitoring of the invention sets annular groove in the outer circle of flange,
The inner surface of annular groove is equipped with non-conductive insulating layer, and conductor fluid is perfused in annular groove, so as to pass through monitoring
Whether electrically conduct to monitor whether flange has crackle between conductor fluid and metal flange, to realize the online prison of flange crackle
It surveys so that equipment is maintained in time, so as to avoid the generation of serious accident.
Second, a kind of flange available for flange excircle crack monitoring of the invention when there is the crackle of penetrability, resists
Can in time cracks be glued by freezing liquid conducting resinl, the excessive loss of freeze proof liquid conducting resinl be avoided, so as to improve monitoring
Reliability.
3rd, a kind of flange available for flange excircle crack monitoring of the invention, annular groove is interior using ceramic coating, right
There is the sensibility of height in crackle, the high sensitivity of monitoring is conducive to obtain the monitoring of early stage and pre- before flange fails
It is alert, avoid the generation of substantial equipment failure or accident.
