Abstract
The utility model relates to a temperature-controlled audible and visual alarm which can perform temperature alarming by utilizing a gas expansion and contraction principle. The temperature-controlled audible and visual alarm consists of a temperature measuring device and an alarming device, wherein the temperature measuring device consists of a thick glass pipe with the diameter of about 20mm, a U-shaped glass pipe with the diameter of about 5mm, and a rubber plug, mercury is filled in the U-shaped glass pipe, gas in the thick glass pipe is sealed by the rubber plug, the mercury in the U-shaped glass pipe is communicated with the sealed gas, a first conductor is contacted with the mercury, and a second conductor is positioned at a temperature alarming position of the U-shaped glass pipe. When a temperature rises, the volume of the gas in the glass pipe is expanded, and the mercury is pressed in the U-shaped pipe; and when the mercury level contacts the second conductor, an alarming circuit is connected to realize alarming. The temperature-controlled audible and visual alarm can conduct remote alarming control on the temperature of a place at a temperature of lower than 350 DEG C and under hard conditions.
Description
Technical field
The utility model relates to a kind of temperature control audible-visual annunciator.
Background technology
At present, common thermometer is processed according to the liquid principle of expanding with heat and contracting with cold, and thermometric liquid is generally alcohol or kerosene, and 78.5 ℃ of the boiling points of alcohol, 150 ℃ of the boiling points of kerosene are so can't measure the temperature of high temp objects.The utility model is to utilize the principle of expanding with heat and contracting with cold of gas to carry out the device of temperature alarming.
Summary of the invention
The utility model provides a kind of easy to use, simple temperature control audible-visual annunciator of making.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of temperature control audible-visual annunciator comprises temperature measuring equipment and warning device; Temperature measuring equipment comprises the about 20 millimeters raw glass pipe of a diameter, about 5 millimeters U-shaped glass tube, the rubber stopper of a diameter, in the U-shaped glass tube mercury is housed, the gas in the rubber stopper sealing raw glass pipe; Mercury in the U-shaped glass tube communicates with sealing gas, and first lead contacts with mercury, and second lead is positioned at the alarm temperature position of U-shaped glass tube; When temperature raises, the volume expansion in the glass tube, mercury is pressed into the U-shaped pipe; When the mercury face contacted second lead, warning circuit was connected, and realized reporting to the police.Warning device comprises electromagnet, armature plate, sounding alarm, light emitting diode and power lead.
Description of drawings
Fig. 1 is a temperature control audible-visual annunciator installation drawing.
Wherein: 1 is the raw glass pipe, and 2 is the U-shaped glass tube.
Embodiment
Referring to accompanying drawing 1, the utility model mainly is made up of temperature measuring equipment and warning device two parts, and temperature measuring equipment comprises the about 20 millimeters raw glass pipe of a diameter 1, about 5 millimeters U-shaped glass tube 2, the rubber stopper of a diameter; In the U-shaped glass tube mercury is housed, the gas in the rubber stopper sealing raw glass pipe 1, the mercury in the U-shaped glass tube 2 communicates with sealing gas; First lead contacts with mercury, and second lead is positioned at the alarm temperature position of U-shaped glass tube 2, when temperature raises; Volume expansion in the raw glass pipe 1; Mercury is pressed into the U-shaped pipe, and when the mercury face rose contact second lead, warning circuit was connected.The warning device (not shown) comprises electromagnet, armature plate, sounding alarm, light emitting diode and power lead.
Because the boiling point of mercury is 356.7 ℃; And has electric conductivity; So the utility model can be lower than 350 ℃ to temperature; The control of temperature long-distance alarm is carried out in the place that condition is comparatively arduous, the innovative point of the utility model: the one, utilize the gas principle of expanding with heat and contracting with cold, and the 2nd, temperature under the hot environment is realized long-distance alarm.
Claims (2)
