Abstract
The utility model relates to a double metal bar type thermometer, comprising a thermometer hand, a core axle, helical bimetallic thermally-sensitive members, a casing tube, a thermometer dial, a protective sleeve, a top cover, a pressing cover and a pressing ring. The thermometer hand, the core axle, the helical bimetallic thermally-sensitive members, the casing tube and the thermometer dial can be connected together, and the tubular part of the protective sleeve bottom is integrated. The utility model not only can make the measuring result not form an error because of the thermometer dial rotation but also can be not damaged by the effects of medium corrosion. The utility model has the advantage of easy manufacturing, and can be widely used for equipment which need temperature measurement for living, medical care, industry, etc.
Description
The utility model relates to a kind of thermometal rod-type thermometer.
At present, the general rod-type bimetallic thermometer of Shi Yonging, its dial plate are only pushed down by top cover and trim ring and are maintained fixed, in case top cover and trim ring are loosening in the use, dial plate will rotate, and makes measurement result produce error.In addition, its protective sleeve bottom is with a plug sealing, and the sealing means of this welding not only to the welding requirements height, and requires highly to service condition, and Korrosionsmedium easily makes the welding position damage, and watch core is corroded, and influences serviceable life.
It is accurate that the purpose of this utility model provides a kind of measurement result, and protective sleeve is not fragile, long service life and process easy bimetallic thermometer.
The purpose of this utility model is to realize like this; a kind of thermometal rod-type thermometer; it comprises top cover; gland; trim ring; protective sleeve; indicator; the dial plate that center pit is arranged; mandrel; the spiral fashion bimetallic temperature sensor; the temperature scale mark is arranged on the dial plate; it is characterized in that; it also has a tube wall upper end to have the sleeve pipe of step; insert in the dial plate center pit described sleeve pipe upper end; and rivet with dial plate; fixedly connected with an end of described spiral fashion bimetallic temperature sensor in the lower end; described mandrel passes described sleeve pipe; described spiral fashion bimetallic temperature sensor and dial plate center pit; fixedly connected with described indicator in its upper end; fixedly connected with the other end of described bimetallic temperature sensor in the lower end; described protective sleeve bottom tubular portion is an one; the indicator that links together, mandrel; the spiral fashion bimetallic temperature sensor; sleeve pipe; dial plate is arranged in protective sleeve.
In order to measure the temperature and pressure of saturated steam in the pressure vessel easily simultaneously, the temperature scale mark also can be put on the saturated vapour pressure value of measuring media under this temperature.
The utility model is because the version that has adopted dial plate, mandrel, indicator, spiral fashion bimetallic temperature sensor, sleeve pipe to link together, gland, top cover, trim ring were become flexible, dial plate rotates, and also can not influence measurement result, and measurement result is accurate.In addition, because protective sleeve bottom tubular portion is can not damaging because of the influence of corrosion of one, prolonged serviceable life, processing also is easy to.

Fig. 2 is the dial plate synoptic diagram of thermometal rod-type thermometer
Below in conjunction with accompanying drawing the utility model is further described.
By shown in Figure 1, the sleeve pipe 9 that the upper end has step inserts in the center pit of dial plate 5, and rivets with dial plate, makes dial plate 5 keep and can not rotate under the situation that rotation can be vibrated in operate as normal again under the effect of certain external force.Fixedly connected with an end of spiral fashion bimetallic temperature sensor 6 in the lower end of sleeve pipe 9, mandrel 7 passes described sleeve pipe 9, the center pit of described spiral fashion bimetallic temperature sensor 6 and dial plate 5, fixedly connected with indicator 4 in its upper end, and fixedly connected with the other end of spiral fashion bimetallic temperature sensor 6 in the lower end.The indicator 4 that connects as one, dial plate 5, sleeve pipe 9, spiral fashion bimetallic temperature sensor 6, mandrel 7 are placed in the protective sleeve 8.Protective sleeve 8 bottom tubular portions are one.Trim ring 3 is pressed on the dial plate 5, and top cover 1 covers on the protective sleeve upper opening, and gland 2 is pressed in top cover 1 and protective sleeve 8 lap-joints.
By shown in Figure 2, be to measure the dial plate 5 of steam temperature with table, temperature scale mark 10 places also indicate the saturated vapour pressure value 11 of water vapour under this temperature on the dial plate 5.According to the difference of measuring media, can design the different dial plates that has filament saturation vapor pressure scale.
In use, twisting is upheld in the back because spiral fashion bimetallic temperature sensor 6 is heated, and drive mandrel 7 and indicator 4 rotate, and indicate the temperature and pressure value of the medium of surveying.
Can design the table of different range abilities as required.
