The guiding device of the utility model second aspect is on the basis of the guiding device of first aspect, it is characterized in that, the above-mentioned guide of split comprises: the first funnel, and this first funnel is buckled in the bottleneck of collecting tank; And second funnel, this second funnel is back-off funnel, its opening is relative with the opening of above-mentioned the first funnel, for the conduit of guiding liquids, stretches into above-mentioned collecting tank successively via above-mentioned the second funnel, above-mentioned the first funnel, and the diameter of above-mentioned the first funnel is more than the diameter of above-mentioned the second funnel.
The guiding device of the utility model third aspect is on the basis of the guiding device of second aspect, it is characterized in that, above-mentioned the second funnel is enclosed within outward on above-mentioned conduit.
The guiding device of the utility model fourth aspect is on the basis of the guiding device of second aspect or the third aspect, it is characterized in that, the opening of above-mentioned the first funnel is relative across certain intervals ground with the opening of above-mentioned the second funnel.
According to guiding device as above, can not only prevent that liquid nitrogen from splashing out from liquid nitrogen collecting tank and vaporization and block operator's sight line in air, make operator cannot see situation at the moment, can prevent that liquid nitrogen from changing in nitrogen process because of a large amount of heats that absorb in surrounding atmosphere simultaneously, and make the liquid nitrogen after vaporization be flushed to the valve port of liquid nitrogen container, the danger of valve is freezed in existence, while causing wanting throttle down, cannot be closed, be caused thus unnecessary personnel's frostbite danger and the loss of liquid nitrogen.
In addition, according to guiding device as above, the liquid nitrogen that the wall that can utilize above-mentioned the first funnel to make to be subject to the second funnel (back-off) stops is back in liquid nitrogen collecting tank along the wall of the first funnel, plays the effect of reclaiming liquid nitrogen.
Meanwhile, according to guiding device as above, it is easy for installation, simple in structure, low cost of manufacture, guiding function are obvious, can also prevent that liquid nitrogen from splashing.
Accompanying drawing explanation
Fig. 1 means the schematic diagram of the guiding device using in liquid nitrogen process is got in laboratory filling of the present utility model.
Embodiment
Below, with reference to accompanying drawing, guiding device of the present utility model is described.
Guiding device of the present utility model consists of two funnels (the first funnel 4 and the second funnel 5).
The first funnel 4 is buckled on the bottleneck of liquid nitrogen collecting tank 1.The second funnel 5 is back-off funnels, and its opening is relative across certain intervals with the opening of the first funnel 4.For guiding one end of the conduit 2 of liquid nitrogen, via the second funnel (back-off funnel) the 5, first funnel 4, stretch into liquid nitrogen collecting tank 1.
The other end of conduit 2 is connected with high-pressure liquid nitrogen steel cylinder (not shown).At conduit 2, be provided with high-pressure liquid nitrogen valve 3 midway, when needs are got liquid nitrogen from the filling of high-pressure liquid nitrogen steel cylinder, open above-mentioned high-pressure liquid nitrogen valve 3, so that high-pressure liquid nitrogen pours in liquid nitrogen collecting tank via conduit, stopping filling with while getting liquid nitrogen, close above-mentioned high-pressure liquid nitrogen valve 3, by this, liquid nitrogen just cannot enter in liquid nitrogen collecting tank.In addition, the second funnel 5 can, by being connected such as mating part such as adhesive tapes, will be enclosed within on conduit 2 outside the second funnel 5 with 2, conduit.
The diameter of above-mentioned the first funnel 4 is greater than above-mentioned the second funnel (back-off funnel) 5, by this, utilize above-mentioned the second funnel (back-off funnel) 5 can prevent that liquid nitrogen from splashing out and vaporization and block operator's sight line in air, make operator cannot see situation at the moment, can prevent that liquid nitrogen from changing in nitrogen process because of a large amount of heats that absorb in surrounding atmosphere simultaneously, and make the liquid nitrogen after vaporization be flushed to the valve port of liquid nitrogen container, the danger of valve is freezed in existence, while causing wanting throttle down, cannot be closed, cause thus unnecessary personnel's frostbite danger and the loss of liquid nitrogen.In addition, the liquid nitrogen that the wall that utilizes above-mentioned the first funnel 4 can make to be subject to the second funnel (back-off) 5 stops is back in liquid nitrogen collecting tank along the wall of the first funnel 4.
Those of ordinary skill in the art are easy to expect other advantage and modification.Therefore, its more wide in range aspect on, shown in the utility model is not limited to here and described detail and exemplary embodiment.Therefore, can under the prerequisite of spirit or scope that does not depart from the overall inventive concept of basis limiting as appended claims and equivalent thereof, make various modifications.
For example, in the present embodiment, the diameter of the first funnel 4 is larger than the diameter of the second funnel 5, by this, can not only prevent splashing of liquid nitrogen, eliminated operator's be subject to splashing potential risk of liquid nitrogen frostbite, and can make liquid nitrogen fill with extract operation personnel's sight line sharpening, prevent that liquid nitrogen waste gas from freezing valve and causing the unnecessary loss of liquid nitrogen, simultaneously, the wall that the part liquid nitrogen that splashes out can be subject to the second funnel stops, and is back to liquid nitrogen collecting tank via the first funnel of below, plays the effect of reclaiming liquid nitrogen.But the utility model is not limited to this, the diameter of the first funnel 4 also can with the equal diameters of the second funnel 5.Although, the diameter that the diameter of the second funnel 5 is a bit larger tham the first funnel 4 also can, owing to still existing, cannot reclaim the possibility that the liquid nitrogen that splashes out causes the unnecessary loss of liquid nitrogen, therefore, not satisfactory.
For example, in the present embodiment, high-pressure liquid nitrogen valve is the open and close valve of manually controlling, but the utility model is not limited to this, can be also the electronics open and close valve of controlling by controlling component.
For example, in the present embodiment, guiding device consists of the first funnel, the second funnel (back-off funnel), but the utility model is not limited to this, as long as the jointing at the collecting tank that liquid is collected is provided with guide, the liquid sputtering from above-mentioned collecting tank is stopped, and the aforesaid liquid sputtering is flowed back in collecting tank by guide.Above-mentioned guide can be both the Split type structure consisting of the first funnel, the second funnel as above-mentioned mode of execution, can be also integrative-structure.The inside of above-mentioned guide is communicated with atmosphere.In the situation that above-mentioned guide is integrated, for example, in the side of above-mentioned guide, there are one or more openings that are communicated with atmosphere.In the situation that above-mentioned guide is split, for example, as above-mentioned mode of execution, between the guide (the first funnel, the second funnel) of split, there is gap, to be communicated with atmosphere.If but the inside of above-mentioned guide is communicated with atmosphere, be not limited to above-mentioned mode of communicating.
For example, in the present embodiment, guiding device (guide) only consists of the first funnel, the second funnel (back-off funnel), but the utility model is not limited to this, as long as at least comprise above-mentioned the first funnel and the second funnel, can be also that other device that contributes to drainage or structure is set.
For example, in the present embodiment, guiding device is the device using in liquid nitrogen process is got in laboratory filling, but the utility model is not limited to this, so long as in order to prevent liquid splash, and the liquid that splashes is out reclaimed, all can use guiding device of the present utility model.
