Description
Technical field
The utility model relates to band and detects hole on-line calibration thermocouple technical field, relates in particular to onePlant band and detect hole on-line calibration thermocouple.
Background technology
The at present industry such as leading Aeronautics and Astronautics, military project, metallurgy, machinery in the world, forImprove the quality of products energy-saving and cost-reducing, enhance competitiveness to thermometric accuracy requirement more and moreHeight, existing off-line type discrete component standard mode can't meet the needs of production and scientific research,To this, the thermocouple that can produce online testing calibration is imperative.
According to national standard, for the calibrating of thermocouple, adopt offline mode more, be about to useIn thermocouple take off from installation site, send metrological service calibrating, can only check at the sceneInstrument, but the mean time between failures of instrument is very long, the probability going wrong is very little;On the contrary, thermocouple in use by aging generation burn into, its deteriorated be irresistible,Unavoidable.
Utility model content
The purpose of this utility model is the shortcoming existing in prior art in order to solve, and proposeA kind of band detects hole on-line calibration thermocouple.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of band detects hole on-line calibration thermocouple, comprises terminal box, a side of described terminal boxBe provided with installing port, in described installing port, be inserted with terminal plate, the middle part of described terminal plate is provided with inspectionGaging hole, described terminal box is provided with binding post away from a side of installing port, in described terminal box, passes throughConnector is connected with tube connector, and described tube connector is connected with protective sleeve away from one end of terminal boxPipe, is provided with some thermocouple entity inner cores, described thermocouple entity inner core in described protective casingBe connected by connecting line with terminal box, described connecting line is through the inner chamber of tube connector.
Preferably, between described tube connector and protective casing, be provided with sealing ring.
Preferably, described thermocouple entity inner core is evenly distributed in protective casing, and thermocoupleThe number of entity inner core is 28.
Preferably, the material of described protective casing is metal material.
In the utility model, for overcoming all drawbacks of offline inspection, so must carry outLine detects, and online detection is exactly that detection system is counted inserting prior process under duty at the sceneThe standard transducer of the calibrating of amount department or calibration, utilizes on-the-spot firing equipment to do thermal source, at the sceneTemperature sensor used is calibrated, and current most industrial furnace is not pre-in the time of designStay effect hole, even if there is the measuring junction distance of the sensor that is calibrated and standard couple also to exceed80mm, be therefore difficult to realize the calibration of online coordination. According to on-the-spot actual conditions, I am publicDepartment has developed and a kind ofly can show the thermocouple of real-time verification in work, and it can be used for furnace temperatureControl and record, furnace temperature effect hole can be provided again when needed, the distance of measuring junction is less than5mm, can satisfy the demand, and this device is simple to operate, by protective casing, thermocouple entityThe cooperation of inner core, terminal box, binding post, terminal plate, detection hole and tube connector, makes this dressPut that to realize on-line synchronous calibration convenient simple, for user provides a kind of efficient and fastOn-line calibration thermocouple assembly.
Brief description of the drawings
Fig. 1 is a kind of structure with detecting hole on-line calibration thermocouple the utility model proposesSchematic diagram;
Fig. 2 is a kind of bottom surface with detecting hole on-line calibration thermocouple the utility model proposesStructural representation.
In figure: 1 protective casing, 2 thermocouple entity inner cores, 3 terminal boxes, 4 binding posts, 5Terminal plate, 6 detects hole, 7 tube connectors.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, in the utility model embodimentTechnical scheme be clearly and completely described, obviously, described embodiment is only thisUtility model part embodiment, instead of whole embodiment.
With reference to Fig. 1-2, a kind of band detects hole on-line calibration thermocouple, comprises terminal box 3, connectsOne side of line box 3 is provided with installing port, is inserted with terminal plate 5 in installing port, in terminal plate 5Portion is provided with detects hole 6, and terminal box 3 is provided with binding post 4, terminal box away from a side of installing portOn 3, be connected with tube connector 7 by connector, tube connector 7 connects away from one end of terminal box 3Have protective casing 1, the material of protective casing 1 is metal material, tube connector 7 and protective casingBetween 1, be provided with sealing ring, in protective casing 1, be provided with some thermocouple entity inner cores 2, thermoelectricityEven entity inner core 2 is evenly distributed in protective casing 1, and the number of thermocouple entity inner core 2Be 28, thermocouple entity inner core 2 is connected by connecting line with terminal box 3, and connecting line is wornCross the inner chamber of tube connector 7.
In the utility model, terminal box 3 is connected with protective casing 1, in protective casing 1The thermocouple entity inner core 2 of dress thermocouple, connecing in thermocouple entity inner core 2 and terminal box 3Line plate 5 connects, and has the detection hole 6 for calibration in protective casing 1, and the position in hole is being protectedOn the center line of protecting pipe 1, and at a side of thermocouple entity inner core 2, protective casing 1Material can be metal material, can be also ceramic material etc., thermocouple solid core 2 canTo be noble metal S, B, R etc., can be also K, E, N, J, T, etc. cheap metal, heatThe internal structure of galvanic couple entity core body 2 can be single or two, and online detection is exactly to detect systemUnite and under duty, pass inserting the prior standard through metrological service's calibrating or calibration at the sceneSensor, utilizes on-the-spot firing equipment to do thermal source, at the scene temperature sensor used is carried out to schoolAccurate. Current most industrial furnace is in reserved effect of when design hole, is calibrated even if havingThe measuring junction distance of sensor and standard couple has also exceeded 80mm, is therefore difficult to realizeThe calibration of line coordination.
The above, be only preferably detailed description of the invention of the utility model, but the utility modelProtection domain be not limited to this, be anyly familiar with those skilled in the art in this practicalityIn the technical scope of novel exposure, according to the technical solution of the utility model and utility model structure thereofThink to be equal to and replace or change, within all should being encompassed in protection domain of the present utility model.
