Abstract

The utility model relates to an internal heat tracing device for a magnetic floater level meter. The level pipe of the magnetic floater level meter is provided with a floater provided with magnetic steel, and the outer side of the level pipe is provided with a magnetic steel-plate level display mechanism The pipe wall of the level pipe is provided with upper and lower sampling pipes which are communicated with a blow-off pipe and the inner chamber of the level pipe. The blow-off pipe is provided with a blow-off valve, and the level pipe is provided with an internal heat tracing pipe. The internal heat tracing pipe penetrates the magnetic floater in the clearance floater and hermetically extends out from end covers at the two sides of the level pipe. The heat tracing pipe is provided with a heat source which can prevent the liquid in the level pipe solidifying. The utility model has the advantages of complete heat tracing, free float of the floater, accurate level measurement and energy saving.

Description

Companion's thermic devices in the magnetic float liquid level gauge

The utility model relates to industrial instrument, companion's thermic devices in a kind of specifically magnetic float liquid level gauge.

The magnetic float liquid level gauge is by on the float, move down and drive colored cylinder flip displays reading, this display device does not directly contact with liquid level, it is clear to have reading, can be by advantages such as liquid contaminations, thereby be widely used in oil, the liquid level of industry tank body containers such as chemical industry shows, under some condition of work, fluid in the liquid level gauge can be because of cooling, solidify and influence the lifting of magnetic float, it is inaccurate to cause obtaining liquid level reading or reading, to apply companion's heat to liquid level gauge for this reason, companion's hot mode of prior art is that the liquid level tube outer wall at liquid level gauge applies companion's heat, for example be wound in the caliber outer wall with the hollow tubular curl, by thermal source, this companion's hot mode exists companion's heat not saturating in the spiral pipe, shortcomings such as it is floating not to be prone to float, and level readings is inaccurate.

The purpose of this utility model is to overcome above-mentioned shortcoming, and companion's thermic devices in a kind of magnetic float liquid level gauge that has improved is provided, and reaches companion's heat fully, and float floats freely, and level gauging is accurate, and purpose of energy saving.

The purpose of this utility model is achieved in that

Companion's thermic devices in a kind of magnetic float liquid level gauge, the float of band magnet steel is housed in the liquid level tube of its magnetic float liquid level gauge, there is magnetic steel plate type liquid level indication mechanism in the liquid level tube outside, the liquid level tube tube wall is provided with upper and lower stopple coupon and blow-off pipe communicates with the liquid level tube inner chamber, blow-off pipe is equipped with blowoff valve, it is characterized in that: an interior trace pipe is housed in liquid level tube, should pass magnetic float with clearance fit by interior trace pipe, from the liquid level tube end covers at two sides, pass hermetically, the thermal source that prevents that the liquid level liquid in pipe from solidifying is housed in this trace pipe.

During enforcement, the thermal source that the liquid level liquid in pipe solidifies that prevents that is equipped with in the described trace pipe can be the hot fluid that circulates, and these trace pipe two ends are provided with the pipe adapter that connects hot fluid source.

During enforcement, the thermal source that the liquid level liquid in pipe solidifies that prevents that is equipped with in the described trace pipe also can be heating wire, and these trace pipe two ends are provided with the binding post that connects heating wire.

Cylindrical at described liquid level tube is provided with the valve jacket that insulation material is made.

The utility model has following actively useful effect:

1, companion's heat is complete, and the liquid corrode state in the liquid level gauge is good, and float floats flexibly, and level readings is accurate, and measurement effect is good.

2, widely applicable, except that can be used for general water, fluid body, be more suitable for being used for inflammable, explosive fluid for example gasoline, liquefied gas etc., when environment temperature is higher, also can lower the temperature by cold water.

3, when producing phase companion thermal effect, the about heat energy of the outer companion's thermal center of interior companion's heat.

Now in conjunction with the accompanying drawings with preferred embodiment.

Fig. 1 is the profile synoptic diagram of a kind of embodiment of the utility model.

Fig. 2 is the axial cut-open view of Fig. 1, shows its internal structure, for using the embodiment of heat source fluid.

The same Fig. 2 of Fig. 3 is for using the embodiment of electric heating thermal source.

Companion's thermic devices in the magnetic float liquid level gauge of the present utility model, the float 2 of band magnet steel is housed in the liquid level tube 1 of its magnetic float liquid level gauge, there is magnetic steel plate type liquid level indication mechanism 3 in liquid level tube 1 outside, the tube wall of liquid level tube 1 is provided with, following

stopple coupon

4,5 and blow-off pipe 6, each communicates with the inner chamber of liquid level tube 1, blow-off pipe 6 is equipped with blowoff valve 7, an interior trace pipe 8 is housed in liquid level tube, should pass magnetic float 2 with clearance fit by interior trace pipe, from liquid level tube end covers at two sides 9, pass hermetically in 10, the thermal source that prevents that the liquid level liquid in pipe from solidifying is housed, end cap 9 in this trace pipe, 10 inboard is fixed with the spring that has moved buffer action 16 to float 2.

In embodiment illustrated in fig. 2, preventing of being equipped with in the described trace pipe 8 thermal source that the liquid level liquid in pipe solidifies is for example steam, a hot water of the hot fluid that circulates, and these trace pipe two ends are provided with the pipe adapter 11,12 that connects hot fluid source.

In the embodiment shown in fig. 3, what be equipped with in the described trace pipe 8 prevents that the thermal source that the liquid level liquid in pipe solidifies from being heating wire 13, and these trace pipe two ends are provided with the binding post 14,15 that connects heating wire.

During enforcement, be provided with the valve jacket (accompanying drawing does not show) that insulation material is made at the cylindrical of described liquid level tube.

During enforcement, described magnetic float 2 can be spherical, cylindric, taper and other shapes, and described trace pipe 8 can be pipe, square tube, special pipe, and this trace pipe can be one, also can be two or many.
