In order to address the above problem, the technical solution adopted in the utility model is: gaseous tension formula thermometer, comprise housing, be provided with erecting frame in the housing, the permanent elastomeric spring duct member of C shape, anti-dress core of pressure meter, the permanent elastomeric spring duct member of described C shape is fixed on the erecting frame, described anti-dress core of pressure meter is installed on the permanent elastomeric spring duct member of C shape, the pointer that anti-dress core of pressure meter is provided with index dial and can be driven by the permanent elastomeric spring duct member of C shape, described housing is provided with the temperature-sensitive pipe that is communicated with by the permanent elastomeric spring duct member of kapillary and C shape, gassy medium in the temperature-sensitive pipe outward.
The permanent elastomeric spring duct member of described C shape is made up of special stand, shift end web member, C shape bourdon tube, described C shape bourdon tube is made of along the periphery welding two constant modulus alloy sheets, and described special stand and shift end web member are weldingly fixed on the two ends of C shape bourdon tube respectively.
Described special stand comprises that the upper and lower mounting plane and the front that are bent to form by sheet material are bent to form upper and lower lip relatively, the middle microscler room that keeps.
Described anti-dress core of pressure meter is connected by trimming piece with the shift end web member.
Described temperature-sensitive pipe and extracapillary are provided with protection tube.
Described gas medium is a nitrogen.
Owing to adopt above-mentioned structure, when the temperature at temperature-sensitive pipe of the present utility model place changes, gas medium in the temperature-sensitive pipe produces the physical phenomenon of expanding with heat and contract with cold accordingly, pressure in the temperature-sensitive pipe is increased or reduce, produce displacement by the permanent elastomeric spring pipe of kapillary and the C shape that is connected together with the temperature-sensitive pipe, drive the rotating shaft of anti-dress core of pressure meter, the pointer that is contained in the rotating shaft is rotated, on index dial, point out to measure temperature value.The material of the permanent elastomeric spring pipe of described C shape has adopted good heat resistance, be subjected to variation of ambient temperature to influence little parelinvar, guaranteed that the utility model thermometer can also normally use in the environment of high heat, guaranteed the measurement accuracy of marine diesel delivery temperature.Described temperature-sensitive pipe is built in the outer protection tube, has improved the shock-resistant ability of temperature-sensitive pipe, gassy medium in the described temperature-sensitive pipe.In the described housing damping oil is housed, has improved the anti-ability of shaking of thermometer.
The utility model compared with prior art, the level that possesses skills height, rational in infrastructure, good manufacturability, reliable in quality, advantage such as performance is more stable, and the antivibration ability is strong, and the temperature-sensitive pipe is shock-resistant and significantly improve serviceable life.
