Abstract
The utility model discloses a kind of low temperature anti-fog type magnetic double level gauge panels, mainly turn over pearl including panel, translucency plastic round tube, magnetic.Magnetic turns over pearl and is mounted in translucency plastic round tube, using the moisture in inert gas replacement translucency plastic round tube, in translucency plastic round tube will not frosting, neither influence observation sight, nor affect on magnetic and turn over pearl rotation, measurement result is accurate and reliable.
Description
Technical field
The utility model relates to magnetic double level gauge panel fields, more particularly to a kind of magnetic that can be used under cryogenic
Flap level gauge panel.
Background technique
Existing low temperature anti-fog type magnetic double level gauge panel is mostly glass tube with vacuum structure, and glass tube with vacuum has difficult fortune
It is not easy to repair after defeated, easy to damage, vacuum breaking；And vacuum tube is with the extension of use time, easily enters air and causes vacuum degree
It reduces, certain moisture is contained in the air of entrance, easy frosting under cryogenic stops observation sight, while magnetic being caused to turn over
Pearl is unable to normal rotation, and level gauging is caused to be distorted.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of low temperature anti-fog type magnetic double level gauge panel, the utility model
It adopts the following technical scheme that
A kind of low temperature anti-fog type magnetic double level gauge panel, specifically includes that panel, round tube, magnetic turn over pearl.
The panel is converted by stainless steel plate, and equipped with bracket for fixing round tube inside panel, panel surface posts ruler
Very little scale is used to indicate liquid level registration.
The round tube, material are that polycarbonate, polymethyl methacrylate etc. have good light permeability material, can be in low temperature
Under the conditions of use.
Further, the cryogenic conditions are -20 DEG C~-50 DEG C.
Further, round tube having a size ofRound tube both ends seal and are equipped with valve, are full of inertia inside round tube
Gas.
Further, valve is made of intake valve and exhaust valve, and intake valve is located at the top of translucency plastic round tube；Row
Air valve is located at the bottom end of translucency plastic round tube, and exhaust valve material is 304, is connected by 1/4NPT nipple and plastic round tube
It connects.
Further, the inert gas is the gases such as nitrogen, carbon dioxide, remains micro-positive pressure in plastic round tube
State.
The magnetic turns over pearl, is mounted in plastic round tube.
The utility model has the beneficial effects that
1, plastic round tube is hardly damaged instead of glass tube with vacuum, convenient transportation, and is replaced conveniently, easy-maintaining.
2, the panel plastic round tube translucency is good, using inert gas replacement air therein, protects always in plastic round tube
Slight positive pressure state is held, and inert gas can be passed through at any time and be replaced, which solves vacuum when worst cold case
Vacuum degree is lowered into air and causes frosting pipe with the extension of use time, stops that observation sight, magnetic turns over pearl normally to turn
Dynamic the problem of causing level gauging to be distorted.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is this
Some embodiments of utility model, for those of ordinary skill in the art, without creative efforts, also
Other drawings may be obtained according to these drawings without any creative labor.

Fig. 2 is the utility model low temperature anti-fog type magnetic double level gauge panel circular tube structure schematic diagram.
Wherein, 1, panel；2, translucency plastic round tube；3, magnetic turns over pearl；4, bracket；5, scale；6, intake valve；7, it is vented
Valve.
Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
The present invention will be further described for 1, attached drawing 2 and embodiment with reference to the accompanying drawing, in order to technology people of the same trade
The understanding of member:
Embodiment 1:
Magnetic turns over pearl 3 and is mounted in polycarbonate round tube, opens intake valve 6 and exhaust valve 7, by intake valve 6 toward translucency
It is filled with inert nitrogen gas in plastic round tube 2, so that the air for containing certain moisture in translucency plastic round tube 2 is passed through exhaust
Valve 7 is discharged, and exhaust valve 7 and intake valve 6 are closed after the completion of inflation.Panel 1 is mounted under -20 DEG C of operating condition, due to translucency
Moisture in plastic round tube 2 is displaced by nitrogen, in translucency plastic round tube 2 will not frosting, neither influence observation sight,
Magnetic is not influenced and turns over the rotation of pearl 3, and measurement result is accurate and reliable.
Embodiment 2:
Magnetic turns over pearl 3 and is mounted in polystyrene round tube, opens intake valve 6 and exhaust valve 7, by intake valve 6 toward translucency
Inert gas carbon dioxide is filled in plastic round tube 2, so that the air for containing certain moisture in translucency plastic round tube 2 be passed through
Exhaust valve 7 is discharged, and exhaust valve 7 and intake valve 6 are closed after the completion of inflation.Panel is mounted under -50 DEG C of operating condition, due to light transmission
Property plastic round tube 2 in moisture displaced by nitrogen, in translucency plastic round tube 2 will not frosting, neither influence observation sight,
It nor affects on magnetic and turns over the rotation of pearl 3, measurement result is accurate and reliable.
Embodiment 3:
Magnetic turns over pearl 3 and is mounted in polycarbonate round tube, opens intake valve and exhaust valve, by intake valve toward translucency plastics
Inert gas carbon dioxide is filled in round tube 2, so that the air for containing certain moisture in translucency plastic round tube 2 is passed through exhaust
Valve 7 is discharged, and exhaust valve 7 and intake valve 6 are closed after the completion of inflation.Panel is mounted under -30 DEG C of operating condition, since translucency is moulded
Material round tube 2 in moisture displaced by nitrogen, in translucency plastic round tube 2 will not frosting, neither influence observation sight, also not
It influences magnetic and turns over the rotation of pearl 3, measurement result is accurate and reliable.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
Within enclosing.
