Description
Technical field
This utility model belongs to measuring instrument technical field, particularly relates to a kind of magnetic being applicable under low temperature use and turns over
Column liquid level meter.
Background technology
Magnetic turning column liquid level meter includes the liquid level tube of the magnetic float built with band magnet steel, realizes liquid level tube and container phase
The connecting tube led to, it is installed on outside liquid level tube and has the display floater of carrying magnetic turned column, above-mentioned for fixedly mounting
The adpting flange of liquidometer, display floater is fixed with liquid level tube the anchor ear being connected.Magnetic turned column is pacified by little axle
Being loaded on display floater, front is white, and reverse side is red, can make 180 ° of rotations around little axle.It is according to buoyancy
Principle and magnetic couplings principle, when liquid level lifting in tested container, the magnetic of the band magnet steel in liquidometer liquid level tube
Property float lifts the most therewith.The turned column red, white being driven display floater by magnetic coupling realizes upset, when in liquid level
When rising, turned column is transferred to redness by white.When liquid level declines, turned column is transferred to white by redness, display floater is red,
It is the actual height of liquid level in tank at position, white boundary, thus realizes liquid level instruction.
Liquidometer of the prior art typically uses the material compositions such as rustless steel, and its shortcoming is: when weather is terribly cold,
Can be because the fluid to be measured within container form ice cube, subsequently in liquidometer, magnetic float is together with ice cube
Swimming in the liquid level tube of liquidometer, corresponding magnetic float position is affected, thus just affects liquidometer
Really measure.
In order to solve above-mentioned traditional liquid level meter inaccurate problem of level gauging under ice condition, the most generally adopt
Method be outside main pipe to be heated, but main pipe is outside easily by outside environmental elements when heating
Impact, and then cause main pipe local heating uneven, cause the liquid medium in main pipe is produced impact,
Potential safety hazard also can be brought time serious；At the weather of extreme cold, it is nearly whole survey to main pipe heat time heating time
The examination time, once stop the liquid in heating main pipe can regelation at short notice, the energy of consumption is big.
Utility model content
The purpose of this utility model was for above-mentioned liquidometer the lacking during measuring with heating function
Falling into, design one can make testing liquid melt, and reduces again and liquid medium in main pipe is produced impact, moreover it is possible to
Reduce the side-mounted magnetic turning column liquid level meter of consuming cost.
For the attainment of one's purpose, the technical scheme that this utility model provides is:
A kind of vacuum thermal insulation chuck liquidometer of the present utility model, including shunt valve, float, display floater,
Connecting tube and adpting flange, it is characterised in that: it also includes vacuum jacket and steam jacket, described vacuum clip
Being set in outside shunt valve, there is the air gap between vacuum jacket and shunt valve, described steam jacket is located at
Outside vacuum jacket, there is the air gap between steam jacket and vacuum jacket, on steam jacket, connection has some
Steam inlet and condensation-water drain.
The vacuum thermal insulation chuck liquidometer that this utility model relates to not only is designed with steam jacket, is additionally provided with true
Empty chuck, vacuum jacket can be used alone, it is possible to the steam jacket outside cooperation uses.When test environment temperature
Be not the lowest in the case of, vacuum jacket independent role, prevent the external world cold air interference cause bypass intraluminal fluid
Body freezes；When test temperature is the lowest, and vacuum jacket effect is not enough to the impact preventing cold air to liquid, uses
Vacuum jacket and steam jacket act on jointly, and now, the heat that steam jacket produces is simultaneously on shunt valve tube wall
And in vacuum area, start diffusion, and then make generally in the state being heated evenly on the outer wall of main body tube,
And after stopping conveying steam, vacuum jacket plays the effect of insulation, reduces energy resource consumption.
Described steam inlet is arranged on the sidewall of steam jacket or is arranged in connecting tube.
Described condensation-water drain is arranged on steam jacket sidewall position on the lower.
As preferably, described float uses magnetic float, and corresponding display floater uses magnetic column to show
Panel
As preferably, being also equipped with liquid-level switch bottom described liquid level tube, liquid-level switch passes through flange and liquid level
Pipe connects, it is achieved liquid level or liquid level bound are reported to the police and control, it is possible to realize the output of two-wire system 4-20mA signal.
The technical scheme using this utility model to provide, compared with prior art, has the advantages that
(1) liquidometer of the present utility model adds vacuum jacket and steam jacket, solves liquid level in winter and surveys
Measure the inaccurate problem of measurement caused due to liquid icing.
(2) vacuum jacket of the present utility model also acts as the effect uniformly heating test liquid, prevents liquid from adding
The uneven potential safety hazard caused of heat, can reduce the consumption of energy consumption when adding hot liquid simultaneously, play solution cost
Effect.
