Embodiment
Press and make a high precision temperature control device of the present utility model shown in Fig. 1,2, thermal induction element 6 adopts bimetallic strip or other thermal sensing elements, and heater element 10 is heating wire or ribbon heater.That insulation sleeve 8 adopts is high temperature resistant, insulation, glass fiber material that heat conduction is good are made.Micromatic setting comprise adjust porcelain knob 13, packing ring 14, fine setting screw mandrel 15, fine setting screw 16,, adjusting porcelain knob 13 links to each other with fine setting screw mandrel 15, fine setting screw 16 is enclosed within continuous adjustment porcelain knob 13 and finely tunes outside the screw mandrel 15, and fine setting screw 16 is riveted together by packing ring 14 and fixed head 1.Micromatic setting is mainly used in the setting adjustment of dispatch from the factory prosodetic temperature or heat insulation work point.Also be working point temperature inadequately accurately the time, can after mixing up it be shut by adjusting micromatic setting.Two connection terminals 4 connect power supply.Be wrapped in the number of turns of the outer heater element 10 of thermal induction element 6 insulation courses 8 and bearing power, qualification or and holding temperature be complementary, also relevant with width, the thickness of heater element ribbon heater 10.As limit 320 ℃ of temperature, and the ribbon heater that is wrapped on the bimetallic strip 6 is 3 circles, the bearing power of corresponding coupling is 2100W.Be incubated 80 ℃, the ribbon heater that is wrapped on the bimetallic strip 6 is 4 circles, and the bearing power of corresponding coupling is 900W.The bimetallic strip 6 that adopts is also different and different with the control temperature.Insulation sleeve 8 is sleeved on outside the bimetallic strip 6, ribbon heater 10 or heating wire are fastened outside insulation sleeve 8, be mainly used in the insulation of 6 of heater element 10 and bimetallic strips, heater element 10 is serially connected in the load circuit, two exits, one termination stationary contact brace 5, the other end is fixed on the end of thermal induction element bimetallic strip 6.Quiet, moving contact brace 5,12 links to each other by support porcelain knob 11, adjustment porcelain knob 13 with the micromatic setting of top, and insulation porcelain ring 3 is placed by riveted pipe 7 riveted and fixed together in fixed head 1, two binding posts 4, interval.
The course of work is as follows: electric heating tube, heater element 10, the contact 9 formation load circuit that is in series.When load gets when electric, be fixed on the bimetallic strip 6 heater element 10 also simultaneously, the heat that heater element 10 is distributed directly conduction is given bimetallic strip 6, make bimetallic strip 6 produce thermal bending deformation, contact 9 disconnections that are serially connected in the load circuit stop to produce heat, the load outage stops to produce heat, along with heat radiation bimetallic strip 6 natural cooling, the flexural deformation of bimetallic strip 6 recovers, it is connected on contact 9 adhesives in the load circuit, load and be fixed on the bimetallic strip 6 heater element 10 again simultaneously electric, above process moves in circles, and reaches by the heater element 10 that is fixed on the bimetallic strip 6 to control the purpose that contact 9 is switched on or switched off.Because thermal induction element bimetallic strip 6 is made as one with heater element 10, the heat that is fixed on heater element 10 generations on the bimetallic strip 6 directly acts on the flexural deformation of bimetallic strip 6, thereby has reduced the action inertia of bimetallic strip 6, has improved control accuracy.
Shown in Fig. 3,4, be the fixing high precision temperature control device structure of screw thread, the bimetallic strip 6 bottom insulation porcelain rings 3 outer stators 20 that are provided with.
High precision temperature control device of the present utility model can be used alone or in combination, and the limit temperature that is mainly used in single temperature is or/and insulation.
