Abstract
A flange for flange electrothermal tube, belongs to electric heating appliance, consider simple, cheap, safety, reliable, be suitable for and design.It comprises base plate entity (90), and its base plate has through hole to penetrate and be then fixedly mounted with for electrothermal tube and seal; It is characterized in that: its base plate has downward sedimentation blind hole (40), form the installation position of temperature sensor.
Description
Technical field
The utility model belongs to electric heating appliance, particularly relates to flange electrothermal tube.
Background technology
Flange is fixedly mounted with electrothermal tube (such as U-shaped electrothermal tube) and namely forms flange electrothermal tube.Its possible application is including but not limited to electric heater.In the practical application of flange electrothermal tube, usually relate to temperature sensor (comprising temperature detect switch (TDS) in temperature sensor).Have on flange temperature sensor mounted, such as CN104197505A boiling water heater and the mounting structure of CN201780168U temperature sensor in electrothermal tube two parts of Chinese patent literatures.But existing structure, the sealing for flange forms infringement, or there is the comparatively complicated defect of Structure and energy.
Summary of the invention
The utility model proposes a kind of flange of flange electrothermal tube, its structural manufacturing process is simple, does not damage (not reducing) its sealing.
The technical solution of the utility model is: in base plate entity, arrange sedimentation blind hole at flange bottom plate upper surface, using this sedimentation blind hole as the installation position of temperature sensor.
That is: a flange for flange electrothermal tube, comprises base plate entity, and its base plate has through hole to penetrate for electrothermal tube to be then fixedly mounted with and to seal (such as/especially weld, to cut off the upper and lower faces of base plate concerning heated medium); It is characterized in that: its base plate has downward sedimentation blind hole, form the installation position of temperature sensor.
Usually, what it is desirable to detect is the real time temperature of heated medium under flange bottom plate.Material due to flange is generally good metal (the such as copper of heat conduction, the most common adopted), and thickness is general only at several millimeters, and the sidewall of sedimentation blind hole also participates in heat transfer, so on sedimentation blind hole bottom surface with flange bottom plate below the temperature difference of medium very little, and the waving interval of this temperature difference is little and algorithm is known (surveys, calculates empirical algorithms.The p empirical value of different sensors temperature range is drawn, then " medium temperature=sensor temperature+p × sensor temperature " such as through Actual measurement.); Like this, then, being that error can be tolerated on the one hand, is that error is easy to compensate on the other hand; So above its precision and stability of structure gained sensor values has been enough for the application that the overwhelming majority is not too harsh.
The beneficial effects of the utility model: from said structure and analysis, this technical scheme has simply, cheap, safety, reliable, applicable advantage.

Embodiment
As shown in the figure, a kind of flange of flange electrothermal tube, comprises base plate entity 90, and its base plate has through hole to penetrate for electrothermal tube to be then fixedly mounted with and to seal (such as/especially weld, to cut off the upper and lower faces of base plate concerning heated medium); It is characterized in that: its base plate has downward sedimentation blind hole 40, form the installation position of temperature sensor.
In embodiment, temperature detect switch (TDS) 4 is installed in flange 9 by Screw (not shown) and screw hole 41.
In embodiment, refer to Fig. 5, temperature detect switch (TDS) terminals 491, electrothermal tube 2 binding post 229, electrothermal tube 1 binding post 119, this three is electrically connected to each other; Electrothermal tube 2 binding post 219, electrothermal tube 1 binding post 129 are electrically connected to each other, and connect power supply 0 line; Temperature detect switch (TDS) terminals 492 connect power firestreak; Earth connection can acting flange 9.
Between temperature sensor and its installation position, heat-conducting glue can be filled out.
