Description
Technical field
This utility model relates to a kind of liquid level tube.
Background technology
At present, existing glass-tube liquid level meter is by glass tubing, protection set, upper needle valve, lower needle valve.During measurement, in unlatching
Needle valve, lower needle valve, make fluid to be measured enter in glass tubing, and liquid constitutes disjunctor path at glass tubing, and path is used through adapter
Flange and tested container connect and compose linker, and the liquid level observed through glass tubing i.e. liquid level identical with the liquid level in container is high
Degree.But, at present, liquid level tube operationally, be frequently encountered measured medium due to low temperature cause medium solidification, crystallization, viscosity
The factor increased, thus affect the accuracy of level gauging, solution is to install heat tracing pipe inside liquidometer additional, uses steam
Or liquidometer heated by hot water by heat tracing pipe, to keep liquidometer properly functioning, but pipe laying is needed to connect boiler heat supplying,
Connected mode is complicated, and cost is high, easily breaks down.
Utility model content
The deficiency existed for prior art, the purpose of this utility model sets heater in being to provide one, has certainly
A kind of liquid level tube of heating function.
For achieving the above object, this utility model provides following technical scheme:
A kind of liquid level tube, including glass tubing, upper needle valve, lower needle valve, upper adpting flange and lower adpting flange, glass tubing
It is fixed between upper needle valve and lower needle valve；Colored ball float it is provided with in described glass tubing, it is characterised in that: described glass
The outside of pipe is additionally provided with the protection pipe corresponding with the shape of described glass tubing, and described protection pipe includes high temperature resistant matrix and setting
Transparent region corresponding with described glass tubing side in this high temperature resistant matrix, described high temperature resistant matrix covers connection electricity
Heating film.
Preferably, above-mentioned a kind of liquid level tube, wherein said electric heating film includes inner insulating layer, thick film the most successively
Circuit layer and external insulation layer.
Preferably, above-mentioned a kind of liquid level tube, wherein said high temperature resistant matrix is ceramic matrix.
Preferably, above-mentioned a kind of liquid level tube, wherein said high temperature resistant matrix is high temperature resistant quartz ampoule, with described bright zone
Territory is one-body molded.
Preferably, above-mentioned a kind of liquid level tube, connection is installed in the outside of wherein said protection pipe anti-explosion terminal box.
By using technique scheme, serve following effect compared to existing technology: protection pipe is adopted by this technical scheme
Be made with high temperature resistant matrix, and within it cover connect electric heating film, when liquid level tube operationally, run into measured medium
When causing medium solidification, crystallization, viscosity to increase due to low temperature, can open electric heating film and heat, heat radiates in glass
On pipe, the measured medium to its inside heats, and prevents medium solidification, crystallization, viscosity from increasing.
Accompanying drawing explanation
Fig. 1: this utility model structural representation.
Fig. 2: this utility model protection tubular construction schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in further detail, so that technical solution of the present invention is more
Should be readily appreciated that and grasp.
As depicted in figs. 1 and 2, a kind of liquid level tube, including glass tubing 1, upper needle valve 3, lower needle valve 4, upper adpting flange 6
With lower adpting flange 7, glass tubing 1 is fixed between upper needle valve 3 and lower needle valve 4；It is provided with colour in described glass tubing 3
Ball float 5, it is characterised in that: the outside of described glass tubing 1 is additionally provided with the protection pipe 2 corresponding with the shape of described glass tubing 1, institute
State protection pipe 2 and include high temperature resistant matrix 2.0 and be arranged at this high temperature resistant matrix interior corresponding with described glass tubing side transparent
Region, described high temperature resistant matrix covers connection electric heating film.
Wherein said electric heating film includes inner insulating layer 2.1, thick film circuit layer 2.2 and external insulation layer the most successively
2.3。
Wherein said high temperature resistant matrix 2.0 is ceramic matrix.
Wherein said high temperature resistant matrix 2.0 is high temperature resistant quartz ampoule, one-body molded with described transparent region.
Connection is installed in the outside of wherein said protection pipe 2 anti-explosion terminal box 8.
The protection pipe high temperature resistant matrix of employing is made by this technical scheme, and within it covers connection electric heating film,
When liquid level tube operationally, run into measured medium due to low temperature cause medium solidification, crystallization, viscosity increase time, electricity can be opened
Heating film heats, and heat radiates and heats the measured medium of its inside on glass tubing, prevents medium solidification, knot
Brilliant, viscosity increases.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
