Visual plant for fields such as nuclear power, petrochemical industries and have radioactivity, poisonous and harmful, high-risk chemical sealing field
The sealed product closing, it requires to sealing leak very strictly, how to control sealing leak to become the weight of current industrial circle
Want subject under discussion.
Impact to sealing effectiveness is mainly the change that sealing member seals thrust during service, runs in sealing member
Period, because the change of pressure medium causes the alternation thrust to supported flange, sealing surface compact power can be caused to change；Due to temperature
The change of degree causes the buckling deformation of metal flange face and bolt to produce strain, equally will also result in sealing surface pressure change.If
Thrust amplitude of variation is excessive, will result in sealing thrust deficiency and produces leakage.If it is possible to realize to sealing gasket
Piece is monitored to gasket seal clamping load with to the temperature of sealing surface in running, is possible to seal leakage
Early warning and research and development provide data supporting.However, in prior art, the clamping load to sealing member and sealing member temperature do not exist
The effective and feasible method monitored is realized in operation.
Content of the invention
It is an object of the invention to provide the black box that a kind of sealing state can be monitored, with by sealing on black box
The sealing clamping load in face and sealing surface temperature are monitored detecting the sealing state of black box, thus avoiding leak to send out
Raw.
For reaching above-mentioned purpose, the technical solution used in the present invention is: the black box that a kind of sealing state can be monitored, bag
Include metallic inner, enclose and be located at the metal outer shroud in the portion of week outside described metallic inner, be embedded in described metallic inner and described metal
Nonmetallic sealing ring between outer shroud, is embedded with Fibre Optical Sensor in described sealing ring, and described Fibre Optical Sensor is in described sealing
At least one circle is circumferentially formed in ring.
Preferably, described Fibre Optical Sensor forms a circle in described sealing ring.
Preferably, described black box also includes analyzing for the control receiving the signal that described Fibre Optical Sensor monitors
Instrument, described control analyser and described Fibre Optical Sensor connect with signal.
Further, described Fibre Optical Sensor has head end and tail end, described head end and described tail along its length direction
End is connected with signal with described control analyser respectively.
Further, described metal outer shroud offers extend radially through the portion of week outside it to inside it week portion connection
Hole, described control analyser is connected with transfer wire, described transfer wire pass through described intercommunicating pore and with described Fibre Optical Sensor
Device is connected.
Specifically, the described head end of described Fibre Optical Sensor is connected with described transfer wire respectively with described tail end.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that the sealing of the present invention
The black box that state can be monitored, wherein passes through to arrange around Fibre Optical Sensor annular in shape in the sealing ring of black box,
This makes black box during for sealing whole work under occasion, along the pressure of the upper each point position of Fibre Optical Sensor circumference
The sealing state information such as load, temperature, humidity all can obtain real-time monitoring, in time obtain black box pressure change,
Temperature change and humidity situation of change, such that it is able to carry out early warning to sealing leak in time, prevent the sealing because of black box
The safety problem losing efficacy and leading to, can also provide reliable data supporting for the follow-up research and development of black box simultaneously.

Specific embodiment
Come with specific embodiment below in conjunction with the accompanying drawings technical scheme is further elaborated.
Referring to the black box shown in Fig. 1, Fig. 2, it includes metallic inner 1, encloses the gold being located at metallic inner 1 outside week portion
Belong to outer shroud 2, the nonmetallic sealing ring 3 being embedded between metallic inner 1 and metal outer shroud 2, wherein, in sealing ring 3, be embedded with light
Fiber sensor 4, this Fibre Optical Sensor 4 circumferentially forms at least one circle, Fibre Optical Sensor 4 winding when institute in sealing ring 3
Around centrage be preferably metallic inner 1, metal outer shroud 2 and sealing ring 3 common axial line, Fibre Optical Sensor 4 winding shape
The internal diameter with diameter greater than sealing ring 3 of annular becoming and the external diameter less than sealing ring 3.
In the present embodiment, in sealing ring 3, Fibre Optical Sensor 4 circumferentially forms a circle, and it is right so just can to realize
Completely circumference carries out sealing state monitoring to black box, especially the pressure loading at sealing ring 3, temperature and moisture condition is entered
Row monitoring.Because Fibre Optical Sensor 4 itself is in elongated strip, when Fibre Optical Sensor 4 is arranged in sealing ring 3, Fibre Optical Sensor 4
Head end and tail end be to disconnect, so a circle described herein is not a circle of closed circular.
Referring to shown in Fig. 1, Fig. 2, this black box also includes controlling analyser 5, is supervised for reception optical fiber sensor 4
The signal measuring.The head end of Fibre Optical Sensor 4 is connected with transfer wire 6 respectively with tail end, thus by transfer wire 6 by light
The signal that fiber sensor 4 detects is sent to control analyser 5.Specifically, metal outer shroud 2 offers radially one side to run through
Outside it week portion to inside it week portion intercommunicating pore 23, transfer wire 6 pass through above-mentioned intercommunicating pore 23 and connect control analyser 5 with
Fibre Optical Sensor 4.
Referring to shown in Fig. 3, Fig. 4, when this black box is used for the sealing between first flange 7 and second flange 8, sealing ring
3 two axle side end faces form sealing surface respectively, and the pressure loading, the temperature of sealing ring 3 and the moisture condition that are subject at sealing surface are all
Can be monitored by Fibre Optical Sensor 4, and control analyser 5 is sent to so that black box is whole by transfer wire 6
At sealing ring 3 during work, entirely the sealing state in circumference all can obtain real-time monitoring such that it is able to right in time
Sealing leak carries out early warning, prevents the safety problem leading to because of the seal failure of black box.
To sum up, the black box that the sealing state of the present invention can be monitored, wherein utilizes Fibre Optical Sensor 4 along its length direction pair
The sensitivity characteristics of STRESS VARIATION state, by arranging around Fibre Optical Sensor annular in shape in the sealing ring 3 of black box
4, this makes black box during for sealing whole work under occasion, along the upper each point position of Fibre Optical Sensor 4 circumference
The sealing state information such as pressure loading, temperature, humidity all can obtain real-time monitoring, and the pressure obtaining black box in time becomes
Change, temperature change and humidity situation of change, thus for carrying out early warning to sealing leak in time, prevent because of black box
Seal failure and the safety problem that leads to, can also be that the follow-up research and development of black box provide reliable data supporting simultaneously.
Above-described embodiment only technology design to illustrate the invention and feature, its object is to allow person skilled in the art's energy
Solution present disclosure much of that is simultaneously implemented according to this, can not be limited the scope of the invention with this.All spiritual according to the present invention
