Description
Technical field
The utility model relates to high-temperature molten salt heat utilization field, is specifically related to a kind of high-temperature molten salt gate valve.
Background technique
Valve is equipment the most common in industrial pipeline, and gate valve refers to the valve that closure member (flashboard) moves along the Vertical direction of path center line.Moving direction and the flow direction of flashboard are perpendicular, and gate valve can only standard-sized sheet and complete shut-down, can not be with making adjustments and throttling, and the main cutting action that rises in pipeline.The major advantage of gate valve is that fluid resistance is little, and flowing to of medium is unrestricted, and it is less than stop valve that when standard-sized sheet, sealing surface is subject to the erosion of working medium; Major defect is that in switching process, sealing surface easily abrades, and build and weight are larger.
Fused salt, as a kind of heat transfer heat-storage medium of high heat capacity, is paid close attention to widely.The serviceability temperature interval of fused salt is 250 DEG C-565 DEG C, temperature gradient reaches more than 300 DEG C, and fused salt remains liquid condition in this is interval, so fused salt pipe-line system pressure is very little, in operation interval, fused salt can store the heat that is approximately three times in water under low-pressure state, and this just makes it in commercial Application, have very large advantage.Research shows, uses the generating of high temperature nitric acid fused salt can make solar power station operating temperature bring up to 450-600 DEG C, so just makes steam turbine generating efficiency bring up to 40%.In addition, use fuse salt also can make heat accumulation efficiency improve 2.5 times, thereby reduce the volume of heat storage container.But at so high temperature, conventional gate valve cannot normally use, often occurs leakage phenomenon, because fused salt exists easy coagulability, therefore pipeline and valve outside are all tied with resistance wire, leakage can cause resistance wire short circuit, and to system, operation causes very large loss.
Model utility content
The technical problems to be solved in the utility model is: propose a kind of high-temperature molten salt gate valve, be intended to solve valveless or the valve problem in leak condition for a long time in high-temperature molten salt heat utilization system.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of high-temperature molten salt gate valve, is characterized in that: comprise valve body, valve seat, flashboard, valve gap, valve rod and handwheel; Described valve rod upper end connects handwheel, and described valve rod lower end connects flashboard, and flashboard inserts the valve seat that is arranged in valve inner, and described valve body upper end arranges valve gap; Described valve gap upper end is also provided with swing bolt, swing bolt nut, hold-down grid and pressure filler pressing sleeve, between described valve rod and valve gap, filler is housed; Filler is nuclear energy level graphite, and described hold-down grid is fixed by swing bolt and swing bolt nut, and hold-down grid pushes filler pressing sleeve downwards, makes filler coordinate tightr with valve rod and valve gap.
Between described valve body and valve gap, adopt welding manner to be connected in aggregates.
Described handwheel replaces with electric wheel.
Described valve body, valve seat, flashboard, valve gap and valve rod use casting heat resistant steel moulding.
The beneficial effects of the utility model are:
The utility model provides a kind of high-temperature molten salt gate valve, can at high temperature work, and its reasonable in design, can solve valveless or the long-term leakage problem of valve in current high-temperature molten salt heat utilization neighborhood system.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve seat; 2, flashboard; 3, valve body; 4, valve gap; 5, swing bolt; 6, hold-down grid; 7, swing bolt nut; 8, handwheel; 9, valve rod; 10, filler pressing sleeve; 11, filler.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further set forth the utility model, but following embodiment is only preferred embodiment of the present utility model, not all.Based on the embodiment in mode of execution, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to the protection domain of this patent.
As shown in Figure 1, a kind of high-temperature molten salt gate valve, comprises valve body 3, valve seat 1, flashboard 2, valve gap 4, valve rod 9 and handwheel 8.Valve rod 9 moves up and down by the rotation of handwheel 8, and valve rod 9 lower ends are connected with flashboard 2, and flashboard 2 is followed moving up and down of valve rod 9 and done motion in the same way, and flashboard 2 inserts the valve seat 1 that is arranged in valve body 3 inside, plays the effect of cutting off medium; Valve body 3, valve seat 1, flashboard 2, valve gap 4 and valve rod 9 use Inconel625 casting; Valve body 3 adopts groove opening welding mode to be connected with valve gap 4, is welded as full weld; Between valve rod 9 and valve gap 4, filler 11 is housed; Filler 11 is nuclear energy level graphite; By swing bolt 5 and swing bolt nut 7, by fixing hold-down grid 6, and push filler pressing sleeve 10 downwards, make filler 11 coordinate tightr with valve rod 9 and valve gap 4 by extruding.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is only preference of the present utility model; be not used for limiting the utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
