Embodiment

Fig. 1-Fig. 6 shows according to bimetallic material self-operated thermostatic controller of the present utility model.This bimetallic material self-operated thermostatic controller comprises a shell 1, and an end of this shell 1 is provided with parts 2, and these parts 2 have the pin thread 21 that is used to engage external unit.

Parts 2 are preferably made by brass, have threaded central lumen 22, and this inner chamber 22 is suitable for holding responsive Thermal Control Element 3.This responsive Thermal Control Element 3 comprises temperature-sensitive portion (bulb), and it is provided with threaded end 31, is connected with the inner chamber 22 of parts 2 with permission with matching; This temperature-sensitive portion comprises two blades (for example, steel and aluminium) with different heat expansion coefficient, and these two blade rigid ground are stacked mutually, and an end is fixed in the temperature-sensitive portion, and an other end can freely move; Electric contact or pin 23 are fixed on the end of temperature-sensitive portion.Along with the rising of temperature, the sensitive metal is tending towards expanding more, owing to be subjected to the constraint of an other metal, just resists variation of temperature more, and therefore generation is crooked, has switched electric contact thus.

In the inside of housing 1, have the plate of a band P.e.c. 10, for example trade mark is the plate of vetronite, it is supporting power relay 4.Can be clear that more that from Fig. 5 and 6 this plate comprises P.e.c. 100, itself and plate 10 are integrated, and are suitable for making sensitive element 3 to be electrically connected with power relay 4, and in addition, this plate also comprises and is used for power relay 4 is fixed on element on the described plate 10.Plate 10 comprises the hole 5 that is used for two metal edges being connected with the metal pin 23 of sensitive element 3.More specifically, the metal pin 23 of sensitive element 3 is soldered in the hole 5 of plate 10.The power relay pin of metal edges marginal pore 11 tops by being arranged at plate 10 usually is soldered on the plate 10.Power relay is suitable for working under the state of usually voltage and high electric current, and promptly voltage is in the scope of 12-24 volt, and electric current is at tens amperes numerical value; For example, relay 4 can be worked under the state of 12V and 35A 10 minutes, or worked under the state of 12V and 25A 60 minutes.

What link to each other with plate 10 has two cables 701,702, and wherein, cable 701 is used for providing power supply (12V or 24V usually) to self-operated thermostatic controller, and cable 702 is used to export the signal from power relay 4, and can be used by external unit.Can more be clear that from Fig. 5 and 6, the P.e.c. 100 of plate 10 has metal edges

marginal pore

71,72 and metal edges

marginal pore

73,74, metal edges marginal pore the 71, the 72nd is used to connect the electric wire of feed cable 701, and metal edges marginal pore the 73, the 74th, is used to connect the electric wire of output current 702; P.e.c. 100 comprises the metal tape 75 that hole 5 and hole 11 are interrelated, and comprises an other metal tape 75 that relay is connected with cable 702 and described relay 4 and sensitive element 3 are connected with cable 701.

Plate 10 is used to prevent the interference between the pin 23 of sensitive element 3, it is the interference between the circuit of the output signal sent of power circuit and power relay 4, this situation can cause the short circuit of relay, in any case or it is undesired to make relay 4 self work, the result is to transmit wrong output signal by signal output cable 702.

This technical scheme allows easily to install self-operated thermostatic controller.At the internal application insulating resin 6 of housing 1, epoxy resin for example, so that power relay is subjected to high temperature protection, preferably protection up to 260 ℃.

Manufacturing time has reduced, the designs simplification of device, thus, cost has descended significantly.

This self-operated thermostatic controller is the TCR formula, promptly except sensing temperature, in case reach predetermined value, just causes electric contact to switch, and then is switched on or switched off electric contact.Such self-operated thermostatic controller is used for temperature maintenance in fixing scope, perhaps, in gas and liquid plant, heat exchanger for example, output signal is automatically controlled fluid cooling or heating system.

Fig. 4 shows the circuit of above-mentioned self-operated thermostatic controller, and wherein,

Reference numeral

71 and 72 is represented supply terminals, and

Reference numeral

73 and 74 is represented outlet terminal, its normally closed contact mode, promptly relay 4 is in to electricity condition, and this is the function of sensitive element 3.
