Among first embodiment, described heating line is single core single-screw heating line, and temperature sensor is a temperature sensor on the line that is fixed on single core single-screw heating line.
Among second embodiment, described heating line is a double helix heating line, and its inner core is a spirality heating line, and skin is a temp.-sensing wire, and temp.-sensing wire is a temperature sensor, and temperature sensor is a linear temperature sensor.
The utility model is by the monitored in common to heating line temperature and pad temperature, control box utilizes temperature sensor gained temperature data between temperature sensor and line, control heating line is at the heating power of different phase, realization is to the accurate control of pad temperature, compare with existing electric pad, have the coefficient of safety height, programming rate is fast, pad temperature is high, the temperature-sensitive error is little, the significant advantage of result of treatment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further, wherein:
Fig. 1 is the structural representation of the utility model first embodiment.
Embodiment
Show the basic structure of the utility model first embodiment as Fig. 1, a kind of pair of thermostat galvanothermy pad, comprise pad 1, be located at the heating line 2 that heat is provided for pad 1 in the pad 1, the lead 3 that the heating line connects power supply is provided with the control box 4 of controlling heating line 2 heating powers, the heating line also has access to a temperature detect switch (TDS) 5, is provided with the temperature measuring equipment that is connected with control box 4 of surveying heating line 2 and pad 1 temperature in the pad 1.Pad is made of the PVC sealed insulation layer of parcel heating line, the textile collet of being located at outside this PVC sealed insulation layer.
Among first embodiment, as shown in Figure 1, temperature measuring equipment comprises is located at the temperature sensor 6 that is used to detect heating line 2 temperature on the heating line 2, be located at temperature sensor 7 between the line that 2 on line of heating is used to detect pad 1 temperature, temperature sensor 7 is connected with control box 4 by holding wire 8 between temperature sensor 6, line.Among this embodiment, heating line 2 is lattice-shaped and is distributed in the pad 1, and 2 on the heating line that faces mutually is separated with certain space, and temperature sensor 7 is located at the gap of facing 2 on heating line mutually between line.Because temperature sensor 7 has certain distance with 2 on line of heating between line, so the temperature that temperature sensor 7 is surveyed between line has represented the temperature of pad 1 whole.Among first embodiment, pad 1 used heating line 2 is single core single-screw heating line, and temperature sensor 6 is for being fixed in temperature sensor 6 on the line on single core single-screw heating line.Single core single-screw heating line kind is a lot, as: single-screw PVC line, high temperature resistant single-screw silicon (silicon) line, carbon fibre heater wire, iron be imperial higher temperature line etc. not.
Among second embodiment, its basic structure is identical with first embodiment, difference is: heating line 2 is double helix heating line, double helix heating line is to be made of inside and outside two-layer material, inner core is a spirality heating line, and skin is a temp.-sensing wire, is insulating material between two lines, the outer field temp.-sensing wire of double helix heating line is a temperature sensor 6, and temperature sensor 6 is a linear temperature sensor.Characteristics such as it is good that double helix heating line has the anti-performance of tearing open, is difficult for broken string, safe and reliable.
During the utility model work, in the temperature rise period, the temperature of heating line 2 and pad 1 does not all reach before the design temperature, and heating line 2 can 100% power work.Because of pad 1 improves self temperature by the heat that absorption heating line 2 is passed out, therefore heating line 2 temperature can be higher than pad 1 temperature in the temperature rise period in temperature rise period, and heating line 2, pad 1 do not reach the preceding pad 1 of the temperature of establishing can not reach design temperature earlier.When temperature sensor 6 detected heating line 2 temperature and reaches the limited temperature of setting, control box 4 control heating lines 2 reduced power, with the temperature that is not higher than setting pad 1 are heated, and under slave mode, heating line 2 can be with the excessive temperature work of danger.As the line 2 that generates heat can be controlled in below 110 ℃ and heats.When the pad 1 lasting heat that absorbs 2 transmission of heating line makes pad 1 temperature reach design temperature, be in the temperature maintenance equilibrium stage this moment, required power output still less, this moment, temperature sensor 6 no longer worked, at this moment the temperature that temperature control is detected according to temperature sensor between line 7 by control box 4 line 2 power outputs that reduce to generate heat are kept pad 1 temperature constant.
The utility model is by the common monitoring to line with heating function temperature and pad temperature, and control box utilizes temperature to pass Temperature sensor gained temperature data between sensor and line, the control line with heating function is at the heating power of different phase, and is real Now to the accurate control of pad temperature, compare with existing electric pad, have safety coefficient height, programming rate fast, Pad temperature height, temperature-sensitive error are little, the significant advantage of result for the treatment of.
