Abstract
The utility model discloses a kind of vaporization type magnetic column formula liquid level gauge comprising liquid level gauge supervisor, top/bottom flange and blind flange, float, float limit assembly, bypass connecting tube and the magnetic display body for bypassing connecting flange and being arranged on the outside of supervisor.By increasing the outer diameter of supervisor, the bubble that the liquid easily vaporized is generated in boiling is set to be discharged by increased space, to enable float to stablize in liquid level position.The side that limit assembly can make the position of float be biased to supervisor keeps enough magnetic field intensities that display body is made to work normally to reduce the distance between itself and magnetic display body.The fluid level transmitter that liquid level gauge carries, installation site are in 60 ° with magnetic display body form direction, can reduce the distance between itself and float, ensure enough magnetic field intensities.The utility model is suitble to measure low temperature, the medium that easily vaporizes, has many advantages, such as the operation is stable, is not influenced by vaporization.
Description
Technical field
The utility model is related to a kind of magnetic column formula liquid level gauges, more particularly to one kind is for measuring low temperature, being also easy to produce boiling
Medium in magnetic column formula liquid level gauge.
Background technology
Existing magnetic column formula liquid level gauge includes the supervisor of the built-in float that is magnetic and realizes that supervisor is connected with container
Bypass to constitute linker is taken over, and supervisor outside has the display body with magnetic column, columned magnetic column installation online
In entity, the longitudinally split half on surface is white, half red, when floating ball rises or falls, it can be driven around axis choosing
Dress, according to law of buoyancy and magnetic coupling principle, when floating ball rises, corresponding magnetic column is switched to red towards display body by white
Panel, when floating ball declines, corresponding magnetic column switchs to white towards display body panel, to show liquid level in container by red.
This liquid level gauge accurately realizes the non-contact measurement of liquid level using magnetic coupling principle, but is measuring certain low-boiling Jie
When matter, compared with the heat exchange activity also of external environment acutely, in the process, medium temperature can rise the medium in liquid level gauge
Height will boil when higher than medium boiling point, generate a large amount of bubble, and in narrow liquid level gauge cavity, liquid level will will produce
Greatly fluctuation, float also therefore in the cavity can plays up and down.In this case, think that it is extremely difficult accurately to measure liquid level
's.
Utility model content
The utility model provides a kind of vaporization type magnetic column formula liquid level gauge regarding to the issue above.
In order to solve the above-mentioned technical problem, the utility model provides a kind of magnetic column formula liquid level gauge such as lower structure,
Magnetic display body, top flange and blind flange, flange in the bottom including liquid level gauge supervisor and its outside and blind flange.Supervisor uses
Large-diameter pipe (DN80), float still use nominal outer diameter, and supervisor is interior, and there are one float limit assemblies, and float limit assembly is by three
Position-limiting tube and one group of limiting plate composition, it is characterized in that：Float limit assembly is welded in main body, make float deviate supervisor axis and
It is biased to supervisor side, to reduce the distance between float and magnetic display body, magnetism is made to show that physical efficiency receives enough magnetic
Field intensity.
For the supervisor of the liquid level gauge using the stainless steel tube increased, which adds inner spaces, are generated because of boiling
Bubble is released by increased space, is influenced to allow float to stablize without being vaporized by liquid.
The outside of the liquid level gauge can carry fluid level transmitter and magnetic switch.To ensure that the magnet steel in float can give liquid
Position transmitter and magnetic switch provide enough magnetic field intensities, and the angle of installation and the form direction of magnetism display body are in 60 °.
In conclusion liquid level of the utility model suitable for measurement low temperature, easy vaporized medium, with the operation is stable, no
The advantages that being influenced by vaporization.

(9) there are float limit assembly (8), float (4) to be limited by limit assembly in, be biased to that the side for display body (3) that are magnetic is installed,
Enough magnetic field intensity can be kept to drive turned column to overturn.
As shown in Figures 2 and 3, limit assembly is welded to form by 3 position-limiting tubes (11) and 1 group of limiting plate (10).Limiting plate
(10) arched, it is a piece of every 500mm welding, a float channel is formed with position-limiting tube (11), master is biased to when float being made to work
Pipe side.
As shown in figure 4, there are one transmitter mounting bracket (12), when welding, which passes through to position, protects for welding on the outside of the supervisor (9)
Angle is demonstrate,proved, fluid level transmitter (5) conduit is fixed by screw and locating piece.
The above is the specific constructive form of the utility model, and the present utility model is not limited to the above embodiments,
For those skilled in the art, equivalent variations and part replacement based on concrete structure on the utility model, size and material
It is all within the protection scope of the present utility model.
