Background
In the petrochemical oil refining industry, heavy oil is residual heavy oil obtained after gasoline and diesel oil are extracted from crude oil, and is characterized by large molecular weight and high viscosity. The specific gravity of the heavy oil is generally about 0.82-0.95. The main component of the composition is hydrocarbon, and the composition also contains about 0.1-4% of sulfur and a trace amount of inorganic compound.
Heavy oil is easy to coagulate if the temperature is not controlled tightly because of high viscosity and poor fluidity of the material, high content of various impurities and large component content change.
The temperature is high in the process, and a large amount of steam is generated in a heavy oil device.
At present, a glass plate liquid level meter is used on site, actual liquid level cannot be observed normally, a medium is viscous, the site needs frequent washing and maintenance, and meanwhile, the glass plate liquid level meter has large heat loss, heavy oil materials are easy to condense and cannot be measured normally. Therefore, the liquid level in the container can not be accurately judged in real time on site, and great inconvenience is caused to the operation of the process and the like.
Based on the complex field working condition and the problems in the use of the field liquid level meter, the double-cavity large-cavity magnetic turning plate liquid level meter with high stability, high precision and high definition needs to be customized according to the actual needs of users.
Disclosure of Invention

In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a heavy oil magnetism turns over board level gauge, includes cavity, float, panel, and the cavity passes through nozzle stub and flange and equipment connection, and the cavity includes main cavity, guide arm, accessory chamber, and the guide arm structure is kept apart main cavity, accessory chamber, and the float is established and is moved from top to bottom along the guide arm in the main cavity, and the accessory chamber is equipped with gaseous overflow mechanism.
The main chamber is a float operation area, and the auxiliary chamber can be additionally provided with transmitters such as magnetostriction and the like. The design can be applied in multiple functions, has few leakage points, reduces the cost of users, and is suitable for harsh working conditions with particles or bubbles in the medium. The medium (heavy oil) has higher density and viscosity, and the problem of high medium viscosity can be solved by the gravity action of the floater.
The cavity is internally provided with the guide rod, the floater normally runs along the guide rod in the main cavity, a large amount of generated bubbles overflow from the auxiliary cavity, the large-amplitude shaking of the floater can not be caused, and the phenomenon that the position of the floater is deviated when oil gas or bubbles float upwards to cause false liquid level is prevented.
The further floater is a magnetic floater customized by using titanium materials according to different working conditions, and is of a 360-degree ring magnetic full-closed structure, and a pressure support ring is arranged inside the floater.
In order to reduce the influence of the float 'weight' on the measurement accuracy of the magnetic turn-over plate liquid level meter as much as possible, the float provided by the magnetic turn-over plate liquid level meter is not the same because the float 'weight' is separately designed and produced according to the technical parameters provided by each customer, and each float has a separate detailed record of the design parameters and the temperature-pressure curve chart of the float.
The floater in the magnetic turnover plate cavity does not only move up and down singly in the process of ascending and descending along with the measured medium, and simultaneously can rotate in the cavity. In the traditional magnetic floater design, one magnetic rod is respectively arranged on four sides of a floater, or two magnetic rods are horizontally and crossly arranged, so that when the floater rotates right to the position that the magnetic rod is far away from a turning plate indicator, the phenomenon that the turning plate of the indicator cannot turn over due to insufficient magnetic coupling force caused by too large distance between the magnetic rod and the turning plate indicator can occur; the float of the magnetic turning plate adopts a 360-degree annular magnetic design, so that a magnetic rod can be ensured to be next to the turning plate indicator no matter how the float rotates in the cavity, and the phenomenon of 'turning over' can be effectively avoided due to the fact that the magnetic coupling force between the float and the turning plate indicator is enough.
The floater adopts titanium materials which can resist high pressure better, and normal work under high pressure working condition is realized through special internal support design and welding process. The advantages are that: the float is totally closed and hard in pressure resistance, so that the float is not required to be deflated due to capillary tube blockage, and the potential explosion hazard caused by pressure of the float is not required to be worried, and the float is an advanced, safe and ideal high-pressure float solution at present.
Further, the outside of the cavity is completely wrapped with a steam jacket, and the steam jacket is provided with a steam interface. The steam jacket fully wraps the cavity, and steam is used for heating, so that the phenomenon that the viscosity is increased due to temperature reduction after the medium enters the cavity, and the medium is condensed in the cavity is avoided. The steam jacket ensures that the body temperature of the main cavity is uniformly heated and simultaneously ensures the fluidity of the medium, and reduces the occurrence of blockage of the floater on the cavity wall.
The panel further comprises an indicator, magnetic turning plates and a glass tube, wherein each turning piece of each magnetic turning plate is formed by magnetic powder through die casting and is provided with a 180-degree turning limiting structure, and the glass tube is vacuumized and filled with inert gas.
When the weather changes, a plurality of magnetic turning plate indicators can generate 'water vapor' in the glass tube to influence the field observation, and the reason is caused by the liquefaction of the water vapor in the glass tube; the magnetic turnover glass tube adopts the technology of vacuumizing and filling inert gas such as nitrogen (the liquefaction temperature of the nitrogen is-196 ℃), so that the phenomenon can be avoided.
The magnetic turning plate is not a traditional magnetic turning column, each turning piece of the magnetic turning plate is formed by magnetic powder die casting, and the turning limiting design of 180 degrees is specially carried out, so that the phenomenon of 'turning over' of the traditional magnetic turning column caused by no limiting can be avoided, namely the column turning is indicated to be 'red one and white one'.
And a flushing interface is arranged on a short pipe for connecting the cavity and the equipment. Heavy oil impurities are easy to deposit and adhere to the connecting short pipe and the cavity, even adhere to a floater to influence measurement, and therefore a flushing interface is additionally arranged at the connecting short pipe.

Further, the top of the cavity is provided with a top flange, and the bottom of the cavity is provided with a bottom flange. Flanges are designed at the top and the bottom of the cavity, so that the device is convenient to disassemble and clean during maintenance.
And thrust springs of floats are respectively arranged at the top and the bottom in a main cavity of the cavity. The thrust springs are arranged up and down to prevent the floats from being stuck to two ends in the main cavity.
