Description
Technical field
The utility model belongs to high temperature fluid pipe control field, and in particular to a kind of high-temperature fluorination object fused salt experimental system
Pipe control mechanism.
Background technology
With the increasingly rise of fluoride molten salt fluid interchange research in the world, the reality using fluoride molten salt as working medium is built
Check system is essential.Therefore the flowing control problem of the fluoride molten salt in solution experimental system is needed, that is, realizes experiment system
The pipe control of system.
However, as fluoride salt fusing point height, corrosion mechanism is special, and the experimental system using fluoride molten salt as working medium is transported
Trip temperature is higher than 500 DEG C for a long time.Due to factors such as valve mechanisms, existing mechanical valve is difficult to effective operation, and practice have shown that
Mechanical valve reliability in fluoride molten salt experimental system is difficult to ensure that.
Control aspect is flowed in fused salt pipeline at present, has the technical side much controlled using fused salt solidification come experimental channel
Case.
Such as Chinese patent CN 202401166U provide a kind of melt freezing valve, including melt pipe and valve body, melt
Valve body is penetrated in the middle part of pipe and is tightly connected, and melt pipeline does not have any interface, ensure that zero leakage of melt with valve body both ends,
Melt pipe outer wall forms cylinder refrigerating chamber with valve interior wall, and cold air is passed through into refrigerating chamber can be so that melt curing reaches only
Purpose is flowed, this valve mechanism is simple, easy to operate, but can not realize that pipeline quickly and effectively restores unimpeded.
For another example Chinese patent CN 202612831U provide a kind of melt freezing valve, mainly by steam entrance sleeve, sky
Gas entrance sleeve, air outlet slit are taken over, jacketed pipe, inner connecting tube, housing and spool form, and are passed through the mixed gas of steam and air
Effective cooling can be carried out to the melt of spool and causes its solidification, has the function that close cut-off melt, but the valve body can not
Restore the unimpeded of pipeline, therefore be not suitable for being applied in the pipeline of frequent break-make.
For another example Chinese patent CN 105546164A provide the freezing valve that a kind of high temperature corrosion-resisting medium prepares purifier apparatus
Door mainly includes valve body, introduction segment and export section, using the cooling fin on valve body to internal liquid medium cooling down into
Solid-state realizes the closing of valve, and heating valve body can restore the unimpeded of runner, but the valve realizes work(using curvilinear conduit
Can, unnecessary flow resistance will be introduced, eventually brings larger negative effect to experiment, therefore is not suitable for being applied to villiaumite
In pipeline.
Invention content
In order to overcome the above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of high-temperature fluorination object and melts
Salt experimental system pipe control mechanism, the device are reliably and effectively real by controlling solidification and the molten state of fluoride molten salt
Now to the cut-off of fluoride molten salt pipeline and unobstructed control：Control pipe is flowed fast through in cavity using air, and formation forces pair
Stream, cools down rapidly control pipe, solidifies fluoride molten salt in pipe；It is very big by vacuum heat-insulation using the vacuum state in cavity
Organizational controls tubular heat in ground scatters and disappears, along with the further heat preservation of insulating layer so that heater strip can effective computer heating control pipe,
So as to melt fluoride salt in pipe, control pipe is allowed to restore and is kept unimpeded for a long time.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of high-temperature fluorination object fused salt experimental system pipe control mechanism, including control pipe F, close uniform winding is in control
The electric heating wire C of pipe F outside wall surfaces, the sealing shell D being arranged on outside control pipe F form height between sealing shell D and control pipe F
Closed toroidal cavity is provided with gas inlet tube A and gas outlet tube H, gas inlet tube A and gas vent on sealing shell D
Gas inlet valve B and gas outlet valve G are respectively arranged on pipe H, further include the entire sealing shell D of package, gas inlet tube A,
The gas outlet tube H and insulating layer E of control pipe exposed portion；High-temperature fluorination object fused salt flows through control pipe F, by changing control pipe
The fusing of fluoride molten salt or curdled appearance realize pipe control in F；
When needing the fused salt flowing of prevention high-temperature fluorination object, gas inlet valve B and gas outlet valve G is opened, electricity is closed and adds
Air at room temperature from gas inlet tube A is injected, then flowed out from gas outlet tube H, is cooled down control pipe F by heated filament C, and then
High-temperature fluorination object fused salt in control pipe F is solidified, achievees the purpose that prevent the flowing of high-temperature fluorination object fused salt；
When needing to restore or keeping the flowing of high-temperature fluorination object fused salt, start electric heating wire C, close gas inlet valve B, beat
Gas vent valve G is opened, the air in sealing shell D is extracted out, makes the cavity vacuum in shell, turn off gas vent valve G later,
Control pipe F heatings make fused salt in pipe restore or keep flowing.
The control pipe F is smooth seamless pipe, and from pipe import to outlet, caliber remains unchanged.The sealing shell D is close
High temperature resistant stainless steel hollow cylinder is closed, control pipe F passes through its axle center, connected by welded seal, while sealing shell D and control pipe
The closed toroidal cavity of height formed between F, pumps wherein air, makes vacuum chamber as needed.The insulating layer E by
The heat-insulating materials such as alumina silicate make.The gas inlet tube A and gas outlet tube H welded and installeds are on sealing shell D.
The utility model has the following advantages and beneficial effect：
Property that 1. device difficulty of processing is low, at low cost and operation is simple and reliable is high.
