Abstract
The utility model discloses a cylinder displaying bimetallic thermometer which is suitable for measuring the temperatures of the different working fluids of 0 DEG C-600 DEG C, particularly is suitable for foods and medicine industries. The utility model adopts the driving mode that rotation generated by the heat distortion of bimetallic solenoids is linked with a roller. A reading display device is formed by a diagonal mark line arranged on the roller and the scale line of a viewing window of a sleeve cylinder so that the conversion between the rotation angle of a temperature sensing element and cylinder display can be realized. The utility model has the advantages of simple structure and low manufacturing cost. The cylinder displaying bimetallic thermometer can satisfy the temperature measurement requirements of different operating conditions and can be used for replacing a mercury thermometer and a circular disk displaying bimetallic thermometer.
Description
The utility model relates to the improvement design of bimetallic system cell, mainly be applicable to the temperature test of different working medium.
The thermometer that extensively adopts mainly contains two classes now: a class is a mercury thermometer, and a class is a bimetallic system cell.Mercury thermometer not only mercury evil can be given and produces and use bring unfavorable factor, but also has easily broken, the frangible and visual range shortcoming that can't overcome such as near.The rotation that free end produced when bimetallic system cell utilized the thermal deformation of thermometal solenoid links a pointer at its free end by central shaft, drives pointer by the thermometal solenoid and rotates the displays temperature value.Though this temp measuring method has remedied the deficiency of mercury thermometer, be subjected to the restriction of pointer display mode, observe inconvenience, limitation is very big; And the thermometer volume is big, and the manufacturing cost height can not adapt to the request for utilization of different operating modes.
Task of the present utility model is to improve the dial pointer display mode of existing bimetallic system cell: a kind of convenient reading is provided, and simple in structure, the measuring accuracy height, the cylinder that usable range is wide shows bimetallic system cell.
The utility model utilizes the temperature-sensing element solenoid of bimetallic system cell to produce the principle of corner when temperature variation.The solenoidal free end of thermometal is linked to each other with the less rotatingcylindrical drum of a quality by central shaft, and this cylinder surface has an oblique line sign.Cylinder puts the big slightly sleeve in footpath always outward, and sleeve is provided with a long and narrow watch window, and the window limit is marked with temperature scale, one little section markings in the window on the visible cylinder.During thermometric, the number of degrees that temperature variation is certain, the thermometal solenoid produces a corresponding corner, and the drive cylinder also turns over corresponding corner: the oblique line sign of cylinder surface and the temperature scale line on the view window limit intersect, obtain the temperature reading value, change the slope of cylinder surface oblique line sign and the axial length of cylinder, can adapt to different range of readings, and the requirement of different indexing accuracies.
The utility model temperature intuitive display, accuracy of reading can adapt to the thermometric requirement of different operating modes, and shock resistance, and pollution-free, cost is also low, compares with bimetallic system cell with existing mercury thermometer, and its social benefit and economic benefit are clearly.
Fig. 1 is the synoptic diagram of an embodiment of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is cylinder markings stretch-out views.
Fig. 4 is Figure 1B-B section warning device electric contact synoptic diagram.
Cylinder as depicted in figs. 1 and 2 shows bimetallic system cell, and thermometal solenoid (6) one ends are consolidated by stifle (5) and pretective sleeve pipe (8); The other end and central shaft (7) weld together.Protecting pipe (8), sliding bearing (9), sleeve (11) are installed on the Connection Block (1), and concentric with Connection Block (1).Cylinder (10) is fixed on the central shaft (7) by fastener (12), and central shaft (7), cylinder (10), sleeve (11) three are concentric, guarantees that cylinder (10) rotates without hindrance in sleeve (11).During thermometric, thermometal solenoid (6) produces a corresponding corner because of variation of temperature, and cylinder (10) also turns over corresponding corner because of linking with solenoid (6).Cylinder (10) surface slope is that the markings (3) of K are crossing with the scale mark (2) of view window (4), indicates temperature reading (T).For the influence of the weight that overcomes cylinder (10), central shaft (7) to thermometal solenoid (6) thermal deformation, and compensate because of thermometal solenoid (6) reading error that micro-axial displacement caused, the weight of cylinder (10) and central shaft (7) must adapt with the specification of thermometal solenoid (6).
Cylinder markings stretch-out view as shown in Figure 3 changes slope (K) and axial length (L), and the cylinder of same diameter can adapt to the requirement of different range of readings and reading accuracy.
The electric contact synoptic diagram of warning as shown in Figure 4 and control device, contact (C) is fixed on the cylinder (10), and rotates with cylinder (10); Contact (D) is fixed on sleeve (11) or the loam cake (13), wherein (C) (D) two contacts all be adjustable.When cylinder (10) turns over certain angle, (C) just conducting of (D) two contacts is sent buzzing or light and is shown alarm; Simultaneously also can send a control signal, the needs of satisfied temperature or program automatic control.Contact (C) (D) can be not limited to single according to using needs.
(13) are the sleeve loam cake among the figure (1).
Claims (3)
1, a kind of bimetallic system cell, the rotation and the display device that are produced by thermometal solenoid (6) thermal deformation link the indicated temperature reading, it is characterized in that: the cylinder (10) of band markings (3) is connected with thermometal solenoid (6) by central shaft (7), and link with solenoid (6), cylinder (10) is concentric with the sleeve (11) of band view window (4), and has constituted lenticular display with the scale mark (2) of view window (4).
2, thermometer as claimed in claim 1 is characterized in that: adjustable electric contact (C) is housed in cylinder (10) upper end, one or several adjustable electric contacts (D) are housed on sleeve (11) or loam cake (13).
3, as claim 1,2 described thermometers, it is characterized in that: central shaft (7), sliding bearing (9), the axis of cylinder (10) is concentric.
