In the prior art, the immersion type heating element assembly generally comprises electrothermal tube and ring flange.As shown in Figure 1, electrothermal tube 1 by shell 11, heating wire 12, draw rod 13, fixed cover 14, binding post 15, filler etc. and consist of, heating wire 12 regions are the hot zone of electrothermal tube 1, remainder is the non-hot zone of electrothermal tube.Thermal protector 2 is installed on the ring flange 3, and electrothermal tube 1 is installed on the ring flange 3 and the hot zone of electrothermal tube 1 is bent to the below of non-hot zone, and it has two dot structure features:
(1) the temperature control point B of thermal protector 2 must be higher than the connection bit A that draws rod 13 and heating wire 12;
(2) binding post 15 must be above the temperature control point B of thermal protector 2.
Although the product of this structure meets matrix test specification or the design specification of STRIX or OTTER company, obvious unreasonable part is arranged in application process:
One, the connection bit A that draws rod 13 and heating wire 12 will accomplish difficult realization of absolute positional precision in manufacture process, therefore the electrothermal tube 1 of producing temperature control point B might occur and be lower than the connection bit A that draws rod 13 and heating wire 12, at this moment, if the water surface is higher than the B plane and is lower than the A plane, thermal protector 2 does not reach operating temperature owing to there is water at the B place, but the heating wire 12 between A and the B is still in running order, this moment, electrothermal tube 1 did not have burning prevention function, thereby affected the useful life of electrothermal tube 1;
Its two owing to will realize this structural requirement, the length of electrothermal tube 1 non-hot zone is longer, takies more material cost.
For overcoming above-mentioned technological deficiency, we improve the immersion type heating element assembly.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of immersion type heating element assembly will be provided, and it can prevent dry combustion method effectively, prolongs the useful life of electrothermal tube.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises electrothermal tube, thermal protector and ring flange, and electrothermal tube, thermal protector all are fixed on the ring flange, and the top of electrothermal tube is positioned at the investigative range of thermal protector.
Further, described electrothermal tube, thermal protector all are fixed on the end face of ring flange the same side, and the outer surface of thermal protector end of probe is close at the top of electrothermal tube; Or described electrothermal tube is fixed on the back side of ring flange, and the front of ring flange is provided with the thermal protector mount pad, and thermal protector is installed on the thermal protector mount pad, and the exterior bottom wall of thermal protector mount pad is close at the top of electrothermal tube.
Again further, described thermal protector mount pad is that recess edge is provided with the Nut column of stationary heat protector to the groove of ring flange back side depression, and the end of probe of thermal protector is close to diapire in the groove.
Again further, the exterior bottom wall of described thermal protector mount pad is provided with the stator that clamps the electrothermal tube top.Stator is connected on the exterior bottom wall of thermal protector mount pad by argon arc welding or Laser Welding.The top of electrothermal tube is connected with the soldering of thermal protector mount pad exterior bottom wall.The installation link position of electrothermal tube and ring flange is provided with high temperature resistant sealing compound.
Again further, described electrothermal tube is comprised of non-hot zone and hot zone, and the hot zone is bent to the top of non-hot zone.The non-hot zone of electrothermal tube is horizontally disposed with.
The utility model is compared the beneficial effect that produces with background technology:
1, be positioned at the investigative range of thermal protector owing to the top of electrothermal tube in the utility model, thereby so that thermal protector can be surveyed the peak of electrothermal tube, so can prevent the electrothermal tube dry combustion method comprehensively, the protection electrothermal tube prolongs its useful life.
2; the hot zone is bent to the top of non-hot zone and the non-hot zone of electrothermal tube is horizontally disposed with; thereby guarantee that thermal protector is positioned at the top of the non-hot zone of electrothermal tube; avoided connecting the burning prevention function that accuracy error between the temperature control point of the position draw rod and thermal protector affects electrothermal tube because of heating wire; the non-hot zone of effectively having shortened electrothermal tube simultaneously; avoided background technology because taking into account the connection bit of drawing rod and heating wire; thermal protector temperature control point and binding post three's position relationship and cause the length of the non-hot zone of electrothermal tube long; guaranteeing to have reduced widely the material cost of electrothermal tube under the constant prerequisite of electrothermal tube power.
Description of drawings: Fig. 1 is the structural representation of soaking type electrothermal tube in the background technology;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is not for installing the structural representation of thermal protector;
Fig. 4 is the structure side view of Fig. 3.
Embodiment: referring to Fig. 2; Fig. 3 and Fig. 4; this immersion type heating element assembly comprises electrothermal tube 1; thermal protector 2 and ring flange 3; ring flange 3 fronts are provided with thermal protector mount pad 31; thermal protector mount pad 31 is the grooves to ring flange 3 back sides depression; recess edge is provided with the Nut column 32 of stationary heat protector; thermal protector 2 is fixed in the thermal protector mount pad 31 by screw and Nut column 32; the end of probe of thermal protector 2 is close to the interior diapire of thermal protector mount pad 31; electrothermal tube 1 is fixed on the back side of ring flange 3, and the top of electrothermal tube 1 is connected with the exterior bottom wall soldering of thermal protector mount pad 31.The heat of electrothermal tube 1 is passed to thermal protector 2 by the diapire of thermal protector mount pad 31, and thermal protector 2 is according to the break-make of actual temperature control power supply.
In addition, electrothermal tube 1 also is provided with high temperature resistant sealing compound with the installation link position of ring flange 3, with preventing water leakage.Simultaneously for guaranteeing that further electrothermal tube 1 top closely is connected with thermal protector mount pad 31 exterior bottom wall; the exterior bottom wall of thermal protector mount pad 31 is provided with stator 4 by argon arc welding or Laser Welding, and the top that stator 4 clamps electrothermal tube 1 makes it to be close to the exterior bottom wall of thermal protector mount pad 31.
