Technical field

The present invention relates to liquidometer technical fields, and in particular to a kind of magnetostriction liquidometer resistant to high temperature.

Background technique

Magnetostriction liquidometer, including gauge outfit, magnetic floating ball, table bar have the internal elements such as waveguide in table bar, have arteries and veins in gauge outfit Circuit and echo detecting circuit occur for punching, as shown in Figure 1.Either reach each in high temperature resistant or table bar at table bar Element is intended to high temperature resistant, is all difficult to realize, it would be highly desirable to improve.

Summary of the invention

Reasonable magnetic resistant to high temperature is designed in view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of Flexible liquidometer is caused, is thermally insulated at cylinder bar, without carrying out high temperature resistant processing to internal element, greatly reduces inside The cost of investment of element, high reliablity are practical.

In order to achieve the above objectives, present invention employs following technical proposals: it includes gauge outfit, cylinder bar, internal element, method Orchid, magnet, float；The upper end of cylinder bar is equipped with gauge outfit, and the inside of cylinder bar is equipped with internal element, and the outside of cylinder bar is arranged the method for being fixed with It is blue；It also includes heat-conducting layer and vacuum heat-insulating layer；Heat-conducting layer is set in the outside of cylinder bar, and cylinder bar and heat-conducting layer constituted it is whole Body is plugged in vacuum heat-insulating layer；The flange and float is socketed in the outside of vacuum heat-insulating layer, and wherein float setting exists The lower section of flange；The inside of float, which is embedded, is fixed with magnet.

Further, the heat-conducting layer is upper end opening formula structure.

Further, the upper end wall of the heat-conducting layer flushes setting with the upper end wall of cylinder bar.

After adopting the above structure, the beneficial effects of the present invention are: the present invention provides a kind of magnetostriction liquid resistant to high temperature Position meter, is thermally insulated at cylinder bar, without carrying out high temperature resistant processing to internal element, greatly reduces the throwing of internal element Cost is provided, high reliablity is practical.
