Abstract
The utility model relates to an adjustable highly sensitive pressing controlling constant temperature switch working in various specific temperature ranges. The switch can be arranged on various electric heaters and electric refrigerators with the need of controlling the temperature. The switch is characterized in that the switch is composed of a liquid storing chamber body, a sensor, a seal pressed frame, a seal robber piece, a seal ring, an adjustable pressed frame, a lead line, a spring, an electric contact head, a drive rod system, a lead line lead electricity pressed piece, a seal robber piece system, seal filling material, etc.
Description
A kind of adjustable highly sensitive voltage-controlled thermostat that is operated in all kinds of specific warm areas can be installed on all kinds of electric heating and electric refrigerator that need temperature control, and is especially remarkable to the control action of all kinds of electric heaters that are operated in the normal temperature district.
The temperature-controlling system of present thermostatic control device adopts crystal element more, is operated in the light current state, so the element that needs is many, volume is big, and the cost height can't be applied on low-grade civil electric appliance.
The purpose of this utility model is to be all kinds of electric heating and electric refrigerator, and particularly some low-grade electric heaters are equipped with the temperature control switch.
The adjustable voltage-controlled thermostat of the utility model is by reservoir compartment body (1) as shown in Figure 1, transducer (2), sealing ring (3), sealed pressing frame (4), sealed film (5), adjustable press box (6), lead, spring, electrical contact and drive link system (7), lead, conduction compressing tablet and sealed film system (8), airtight and watertight padding compositions such as (9), its mounting means is equipped with alcohol or kerosene (10) as shown in Figure 1 in the reservoir compartment body (1).Switch assembles under the normal pressure working temperature, when temperature raises, and alcohol or kerosene expansion of liquids, interior pressure increases, and sealed film (5) center is promoted drive link, circuitry cuts by jack-up.When temperature reduces, liquid (10) shrinks, and cavity vacuum occurs in (1), under the atmospheric pressure effect, sealed film (5) center resets into initial position or partly is drawn in the transducer (2), and butt joint, circuit are connected again again under spring action for contact and conduction compressing tablet.Can adjust distance between adjustable press box (6) and the sealed pressing frame (4) according to different working temperatures, realize the temperature control under the different specified temps.This switch is a normally closed type, if make to mix as shown in Figure 2 adjustable press box (6) elements such as into (7), (8), (9), just can become open in usually, and performance is the same.
Accompanying drawing 1 is adjustable thermostatic control construction of switch schematic diagram;
Most preferred embodiment:
Selecting the inner cavity size height of reservoir compartment body (1) as shown in Figure 1 is 5mm, and end radius of circle is 5mm, and the size of piston rod (3) is long to be 30mm, and the volume of alcohol (12) is π R
2H, according to VT=V20 ℃ (1+ β (T-293)) wherein β be coefficient of volume expansion β=1.1 * 10 of alcohol
-3/ degree.After the variations in temperature, volume also changes.If temperature raises 20 ℃, π R is arranged then
2H * β * 20=π r
2△ L.△ L is that piston rod (3) is because the distance of temperature rise jack-up is calculated △ L=11mm.This adjustable thermostatic control switch can be used as the temperature detect switch (TDS) of electric blanket.
Claims (3)
1, a kind of adjustable voltage-controlled thermostat is characterized in that it is made up of reservoir compartment body, transducer, sealed pressing frame, sealed film, sealing ring, adjustable press box, lead, spring, electrical contact and drive link, system, lead, conduction compressing tablet and sealed film system, airtight and watertight padding etc.
2, adjustable voltage-controlled thermostat according to claim 1 is characterized in that reservoir compartment body, transducer, adjustable press box, sealed pressing frame are metalwork or duroplasts spare.
3, adjustable voltage-controlled thermostat according to claim 1 and 2, the material that it is characterized in that sealing ring is a polytetrafluoroethylene, sealed film is a high abrasion soft rubber sheet.
