Description
Technical field
The present invention relates to the thermometric technical field of a kind of special pipeline position, particularly a kind of temperature measuring equipment and installation method thereof that is used for double layer liquid metal sodium pipeline.
Background technology
In sodium-cooled fast reactor, adopt liquid metal sodium as catalyst carrier, and sodium metal can promptly react with airborne oxygen, carbon dioxide and moisture, sodium-cooled fast reactor part loop running temperature is more than 300 ℃ under the high temperature, if high-temperature sodium is directly revealed the danger that will increase the loop operation in air greatly, therefore adopt the isolation of double-skin duct realization to sodium channel.And adopt directly in the thermometer insertion liquid metal for the measurement of liquid metal temperature in the general pipeline, but because the activity of sodium, adopt the measurement of directly thermometer being inserted in the liquid metal sodium to cause its optional equipment more complicated, and because ducted sodium is to flow fast, the device that one cover shearing resistance must be arranged in the sodium of thermometer in flowing, otherwise can not guarantee the safety of thermometer, the more important thing is, perforate on sodium channel has increased danger and the interior resistance of pipeline that sodium channel is revealed greatly.
Summary of the invention
The present invention has overcome deficiency of the prior art, provides a kind of safe and reliable, simple in structure, and processing, installation steps is simple, easily, and can change the temperature measuring equipment that is used for double layer liquid metal sodium pipeline and the installation method thereof of temperature thermocouple at any time.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of temperature measuring equipment that is used for double layer liquid metal sodium pipeline is made up of conduit, cutting ferrule, conduit, and key is that temperature thermocouple extend in the conduit, and passes through the cutting ferrule sealing and fixing at conduit, and catheter head covers on the inner tube of bimetallic tube.
This Unit Installation method comprises that the outer tube with bimetallic tube cuts out oval outer tube; Perforate on oval outer tube, the oval outer tube of perforate is enclosed within on the conduit, pass through following steps then, (1) head that will be with the conduit of oval outer tube covers on the outer wall of inner tube, (2) with conduit and oval outer tube, oval outer tube and pipeline welding, (3) are inserted into the head of conduit with temperature thermocouple along conduit, are fixed on the conduit by cutting ferrule.
In order better to reach sealing, improve accuracy, the security of measuring, the present invention is all right: the cutting ferrule sealing and fixing of described measurement mechanism is that cutting ferrule is threaded in conduit at conduit, between seal by sealing gasket.Described catheter head bending.Leg is welded as 30 ° of welding gun angles, the welding of welding gun head distance solder joint 10mm less than 90 ° of parts between conduit in the step of described installation method (2) and the oval outer tube.
Compared with prior art, the invention has the beneficial effects as follows: adopt the temperature of measuring channel inner tube outer wall to replace directly measuring the sodium metal temperature, do not adopt perforate on inner tube, prevented the danger that sodium channel is revealed, safe and reliable, this apparatus structure is simple, and processing is easy with installation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
A kind of temperature measuring equipment that is used for double layer liquid metal sodium pipeline as shown in Figure 1, form by conduit 1, cutting ferrule 2, temperature thermocouple 3, temperature thermocouple 3 extend in the conduit 1, and pass through cutting ferrule 2 sealing and fixing on conduit 1, present embodiment preferably uses cutting ferrule 2 to be threaded in conduit 1, between again by sealing gasket 4 sealing, damage and inner tube 7 makes liquid metal sodium when revealing is leaked to conduit 1 outside in case prevent further that conduit 1 head from having.Conduit 1 head adopts curved design, has increased the contact area with inner tube 7 outer walls, has shortened the reaction time of temperature thermocouple 3.The A of catheter head shown in Figure 2 is to view, its conduit 1 head is pushed down head by compressing tablet 5 again, compressing tablet 5 is weldingly fixed on by resistance spot welding on the outer wall of inner tube 7 of bimetallic tube, played the effect of two aspects like this, wherein strengthened on the one hand and the contacting of tube wall, when temperature changed, the head of conduit 1 can have a flexible leeway on the other hand, prevented that stress from concentrating and damaged conduit 1.
This Unit Installation method is as follows:
At first the outer tube 6 with bimetallic tube cuts out a part, and the part of cutting is oval outer tube 8; Perforate on oval outer tube 8 is enclosed within the oval outer tube 8 of perforate on the conduit 1; (1) head that will be with the conduit 1 of oval outer tube 8 is pressed in its conduit 1 head by compressing tablet 5 on the outer wall of inner tube 7 of bimetallic tube then, compressing tablet 5 is fixed on the outer wall by resistance spot welding again, (2) with conduit 1 and oval outer tube 8, oval outer tube 8 and outer tube 6 welding, the welding technology that present embodiment preferably adopts is as follows: leg adopts special welding technology less than the welding of 90 ° of parts between conduit 1 and the oval outer tube 8, the welding gun angle is 30 ° as shown in Figure 3, the welding symbol of welding gun head distance solder joint 10mm welds, and remainder adopts common welding technology welding.Oval outer tube 8 and outer tube 6 also adopt common welding technology to weld.(3) temperature thermocouple 3 is inserted into the head of conduit 1 along conduit 1, temperature thermocouple 3 is fixed on the conduit by cutting ferrule 2 and sealing gasket 4.
