Abstract
The utility model discloses a low heat leakage's low temperature stainless steel funnel, funnel shell and the whole funnel cup of funnel inner bag welding together formation, the grab handle welding is on the funnel shell, a lean on the below position for exhausting with sealed coalesced copper sealing of tube in funnel shell one side for the grab handle, the play liquid end of fistulae is the inclined plane shape, it passes funnel shell and funnel inner bag bottom aperture in proper order, and link together with funnel shell and funnel inner bag seal respectively, the vacuum production of coalesced copper pipe is passed through in the space between funnel inner bag and the funnel shell. Provided is an advantage lies in: this kind of low temperature stainless steel funnel can effectively reduce heat -conduction, makes the slow grab handle that just reaches on a small quantity of cold volume, realizes taking of funnel cup, alleviate the frozen phenomenon of fistulae simultaneously, solve the unable smooth infuse with's of liquid nitrogen problem.
Description
Technical field
This patent 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 to use fistulae
Weld with at cup list, during using, usually answer stress that the phenomenon of fracture occurs；And due to
Cup material is monolayer material, and for cryogenic liquid, due to heat-conduction effect, the temperature of cup handle is too low, makes
One-tenth cannot normally be taken liquid nitrogen funnel；And owing to the temperature of fistulae is relatively low, easily cause fistulae icing phenomenon,
Hinder inculcating of cryogenic liquid.
Summary of the invention
Solving the technical problem that of this patent is: overcomes existing connection insecure, and avoids fistulae to freeze
The appearance of phenomenon, and realize 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, and lever 5 is welded on leakage
On bucket shell 2, the oxygen-free copper pipe 3 for aerofluxus Yu sealing is welded on funnel shell 2 relative to the one of lever
The position on the lower of side, the liquid outlet of fistulae 4 is inclined plane shape, and it sequentially passes through funnel shell 2 and leakage
Bucket inner bag 1 small hole at bottom part, and it is connected to one with funnel shell 2 and funnel inner bag 1 welded seal respectively
Rising, between funnel inner bag 1 and funnel shell 2, space is evacuated by oxygen-free copper pipe 3.
This patent provides the benefit that, fistulae is dual with the inner bag of funnel cup and shell to be welded to connect, more
Sturdy and durable；Vacuum state between inner bag and shell effectively reduces heat-conduction effect, can realize low temperature funnel
Normally take and use；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 of this patent heat；
In Fig. 1: 1. funnel inner bag, 2. funnel shell, 3. oxygen-free copper pipe, 4. fistulae, 5. lever.
Detailed description of the invention:
With example, this patent is further illustrated below in conjunction with the accompanying drawings, in FIG, funnel shell 2 and funnel
Inner bag 1 uses argon arc welding mode to weld along weld seam at rim of a cup, forms whole funnel cup, its funnel shell 2
It is hollow state with the gap area in the middle of funnel inner bag 1.
Lever 5 uses spot-welding technology to weld with funnel shell 2, and the welding position of lever 5 is positioned at funnel shell
The central region of 2.
In position on the lower, the opposing side for lever 5 of funnel shell 2, oblique make a call to an aperture, by anaerobic
Copper pipe 4 through aperture and uses soldering tech to weld with funnel shell 2, its purposes for ease of with aerofluxus key
It is connected, can be by funnel interior hollow section vacuum pumping state, after being evacuated, utilizing clamp to clamp will
It presss from both sides flat sealing, and keeps 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 keeps fistulae butt end concordant with bottom funnel inner bag 1, carry out subsequently
Silver soldering connects, it is ensured that secure seal, and realizes inculcating smoothly of cryogenic liquid.
