Abstract
The invention discloses a low-heat-leakage low-temperature stainless steel funnel.A funnel outer shell and a funnel inner container are welded together to form a funnel body, a grabbing handle is welded on the funnel outer shell, an oxygen-free copper pipe used for exhausting and sealing is welded at a low position of one side, relative to the funnel outer shell, of the grabbing handle, a liquid outgoing end of a leakage pipe is in the shape of a bevel, sequentially penetrates the funnel outer shell and a small hole in the bottom of the funnel inner container and is welded, sealed and connected with the funnel outer shell and the funnel inner container respectively, and a gap between the funnel inner container and the funnel outer shell is vacuumized through the oxygen-free copper pipe.The low-heat-leakage low-temperature stainless steel funnel has the advantages that heat conduction can be reduced effectively, cold is slowly and slightly transmitted to the grabbing handle, and fetching of a funnel cup is realized; icing of the leakage pipe is relieved, and the problem that liquid nitrogen cannot be smoothly infused is solved.
Description
Technical field
The present invention relates to a kind of inner vacuum, low drain heat, and can inculcate cryogenic liquid rustless steel funnel device.
Background technology
Low temperature funnel has this important effect in test Dewar field, and conventional funnel cup is all adopt fistulae to weld with cup list place, in the process used, usually answers stress the phenomenon of fracture occur；And owing to cup material is monolayer material, for cryogenic liquid, due to heat-conduction effect, the temperature of cup handle is too low, causes liquid nitrogen funnel of cannot normally taking；And owing to the temperature of fistulae is relatively low, it is easy to cause fistulae icing phenomenon, hinder inculcating of cryogenic liquid.
Summary of the invention
Solving the technical problem that of the present invention is: overcome existing connection insecure, and avoids the appearance of fistulae icing phenomenon, and realizes the hand carried low-temp liquid infusion method that can normally take.
As shown in drawings, the low temperature rustless steel funnel being invented a kind of low drain heat includes funnel inner bag 1, funnel shell 2, oxygen-free copper pipe 3, fistulae 4, lever 5, wherein:
Funnel shell 2 and funnel inner bag 1 are welded together to form whole funnel cup, lever 5 is welded on funnel shell 2, the position on the lower of the funnel shell 2 side relative to lever it is welded on for the oxygen-free copper pipe 3 of aerofluxus Yu sealing, the liquid outlet of fistulae 4 is inclined plane shape, it sequentially passes through funnel shell 2 and funnel inner bag 1 small hole at bottom part, and link together with funnel shell 2 and funnel inner bag 1 welded seal respectively, between funnel inner bag 1 and funnel shell 2, space is evacuated by oxygen-free copper pipe 3.
The invention has the beneficial effects as follows, the inner bag of fistulae and funnel cup is welded to connect with shell is dual, more sturdy and durable；Vacuum state between inner bag and shell effectively reduces heat-conduction effect, it may be achieved normally the taking and use of low temperature funnel；Alleviate fistulae icing phenomenon, it is achieved inculcating smoothly of cryogenic liquid simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure chart of the low temperature rustless steel funnel of a kind of low drain heat of the present invention；
In Fig. 1: 1. funnel inner bag, 2. funnel shell, 3. oxygen-free copper pipe, 4. fistulae, 5. lever.
Detailed description of the invention:
Below in conjunction with accompanying drawing and example, the present invention is further described, and in FIG, funnel shell 2 adopts argon arc welding mode to weld with funnel inner bag 1 along rim of a cup place weld seam, forms whole funnel cup, and the gap area in the middle of its funnel shell 2 and funnel inner bag 1 is hollow state.
Lever 5 adopts spot-welding technology to weld with funnel shell 2, and the welding position of lever 5 is positioned at the central region of funnel shell 2.
In position on the lower, the opposing side for lever 5 of funnel shell 2, oblique make a call to an aperture, through aperture and soldering tech is adopted to weld with funnel shell 2 oxygen-free copper pipe 4, its purposes is for ease of being connected with aerofluxus key, can by funnel interior hollow section vacuum pumping state, after being evacuated, utilize clamp pincers to be pressed from both sides flat sealing, and keep vacuum state.
At vertical direction, all bore the aperture of a formed objects in the bottom of funnel shell 2 with funnel inner bag 1, fistulae 3 is sequentially passed through holes, and keep fistulae butt end concordant with bottom funnel inner bag 1, carry out silver soldering connection subsequently, it is ensured that secure seal, and realize inculcating smoothly of cryogenic liquid.
