Description
Technical field
The utility model belongs to the temperature measurement technology field, is specifically related to a kind of heat sensitive ferrite temperature over-range indicator.
Background technology
The temperature of many equipment equipment in operational process itself all will change, and these situations of change have often reflected the ruuning situation of equipment.The bearing of equipment for example, motor, if the temperature that the joint of transmission line of electricity etc. are located than the unexpected rising of normal operating temperature, then often devices illustrated breaks down at this moment or has potential faults, has influence on the security of operation and the serviceable life of equipment.If can monitor the temperature at above-mentioned position in real time, make the indication of reporting to the police when rising is overheated suddenly in temperature, just can allow the plant maintenance personnel in time find, and make corresponding processing, just can avoid the generation of some serious equipment breakdowns to prevent the equipment failure expanded range.
The device temperature monitoring mode of prior art mainly contains with infrared measurement of temperature equipment or other temperature measuring equipment and carries out regularly or irregularly patrolling and examining, and special temperature online detection system is installed.First method often can not in time pinpoint the problems, and infrared measurement of temperature equipment is subjected to environmental influence to cause measuring error easily owing to be discontinuous measurement.Though second method can detect by real-time high-precision, cost is higher.
Publication number is that the Chinese patent of CN201060059 discloses the out-of-limit indication bolt of a kind of temperature, constitute by shell and the inner core that is positioned at enclosure, wherein inner tank theca is provided with groove, be fixed with the butterfly shaped dual metal sheet of a thick middle, thin edge in this groove, contact the formation screens by extruding between the edge of this butterfly shaped dual metal sheet and the outer casing inner wall.The utility model is installed in the transmission line wire joint, can monitor the temperature of transmission line wire in real time, has the accuracy of detection height, and monitoring location is accurately concrete, advantages such as convenient maintenance and replacing.Its weak point is: said apparatus can only be made the indication action at fixing preset temperature, and the user in use can not adjust and move and postpone greatlyyer, and precision is lower.
Summary of the invention
The utility model provides a kind of heat sensitive ferrite temperature over-range indicator, and purpose is to solve deficiency of the prior art.
The following technical scheme of the concrete employing of the utility model:
A kind of heat sensitive ferrite temperature over-range indicator is characterized in that, comprises indication loam cake, base, indication loam cake hollow, and base outer surface is processed with not locating slot to the end, and the indication loam cake is nested on the base, and both are slidingly matched; Chamber is formed at indication loam cake and base top, is provided with spring in the chamber, and chamber roof is fixed with permanent magnet, be fixed with heat sensitive ferrite on the base in the chamber, scribble eye-catching indication color at the middle and upper part of base outer surface branch, when permanent magnet and heat sensitive ferrite were inhaled together, spring was compressed.
One of the utility model scheme is: described permanent magnet and heat sensitive ferrite are packaged structures.
Two of the utility model scheme is: described permanent magnet is long clavate, and heat sensitive ferrite is a tubular, and both are slidingly matched.
To come off from base in order preventing to indicate loam cake to upspring, in indication, to cover and also be provided with dog screw and cooperate with locating slot.
The utlity model has following beneficial effect:
1) the utility model can accomplish that temperature returns to preset temperature and automatically restores to not alarm condition when following.Promptly can realize only when overheated, reporting to the police the function that cancellation is reported to the police when not overheated.
2) on base, be processed with mounting structure, the convenient installation.
3) pure physical construction guarantees long-time reliable and stable work.
4) simple in structure, low production cost is suitable for promoting the use of on a large scale.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Among the figure, 1 is the indication loam cake, and 2 is spring, and 3 is screw, and 4 is base, and 5 is locating slot, and 6 is heat sensitive ferrite, and 7 is permanent magnet.
Embodiment
As shown in Figure 1, a kind of heat sensitive ferrite temperature over-range indicator comprises indication loam cake 1, base 4, indication loam cake 1 hollow, and base 4 outside surfaces are processed with not locating slot 5 to the end, and indication loam cake 1 is nested on the base 4, and both are slidingly matched; Indication loam cake 1 forms chamber with base 4 tops, is provided with spring 2 in the chamber, and spring 2 is confined state, and chamber roof is fixed with permanent magnet 7, is fixed with heat sensitive ferrite 6 on the base 4 in the chamber, scribbles eye-catching indication color at the middle and upper part of base outer surface branch.
When temperature was under the deliberate action temperature, heat sensitive ferrite 6 had ferromagnetism, and 7 pairs of heat sensitive ferrite 6 attractive forces of permanent magnet of indication loam cake 1 are greater than the elastic force of spring 2.This moment, spring 2 was compressed, and expression is in not alarm condition.Rising along with temperature, when reaching default alarm temperature, heat sensitive ferrite 6 just reaches curie transition temperature and loses ferromagnetism rapidly, 7 pairs of heat sensitive ferrite 6 attractive forces of permanent magnet descend rapidly, when less than the elastic force of spring 2, indication loam cake 1 is upspring under the effect of spring 2, exposes the middle and upper part of base 4, the expression overtemperature alarm waits the related personnel to find aftertreatment.When temperature drop to curie transition temperature when following heat sensitive ferrite 6 recover ferromagnetism again, but permanent magnet 7 has left heat sensitive ferrite 6 a segment distance is arranged, the suction of this moment also is not enough to overcome the elastic force of spring 2, can not return to not alarm condition, can only allow between the two distance be reduced to a certain degree can hold mutually and return to not alarm condition by manually depressing indication loam cake 1.Screw 3 is screwed in the locating slot 5 of base, comes off from base when preventing to indicate loam cake to upspring, and the bottom of base can be according to the screw thread that different size specifications are gone up in needs processing is installed.
As shown in Figure 2, embodiment 2 is substantially the same manner as Example 1, just permanent magnet 7 is long clavate, heat sensitive ferrite 6 is long tubular, temperature is under the deliberate action temperature time, heat sensitive ferrite 6 has ferromagnetism, and the elastic force that permanent magnet 7 attracts heat sensitive ferrite 6 to overcome spring 2 under the effect of magnetic force is inhaled in heat sensitive ferrite 6 center pits.Spring 2 is compressed and is in not alarm condition.When temperature raises and reach default alarm temperature, heat sensitive ferrite 6 also just reaches curie transition temperature and loses ferromagnetism rapidly, 7 pairs of heat sensitive ferrite 6 attractive forces of permanent magnet also descend simultaneously, when less than the elastic force of spring 2, indication loam cake 1 is upspring under the effect of spring 2, the middle and upper part of exposing base 4, the expression overtemperature alarm.This moment, the part of permanent magnet 7 still was in heat sensitive ferrite 6 center pits.When temperature drop to curie transition temperature when following heat sensitive ferrite 6 recover ferromagnetism again, the elastic force that the magnetic force between permanent magnet 7 and the heat sensitive ferrite 6 still is enough to overcome spring 2 is drawn into permanent magnet 7 in heat sensitive ferrite 6 center pits.Automatically restore to not alarm condition.Need not manual intervention.
