Abstract
The utility model discloses a furnace thermal couple, which comprises a high-temperature protective sleeve, and an assembled sensory element equipped in the high-temperature protective sleeve. The assembled thermometry element and an armored sensory element installed with a protective pipe are weled together. The utility model has a good sealing property, while it can prolong the service life of the thermal couple and increase the reliability and safety.
Description
Technical field
The utility model relates to a kind of meter specially of measuring high temperature.
Background technology
Existing thermocouple assembly is assembled by porcelain bead or corundum insulation assembled temperature element or magnesium oxide insulation armored temperature element, outside protective case, technology side coupling arrangement and termination; the temperature element end is placed measured medium; when there are temperature difference in measured medium and thermocouple cold junction; produce electric potential difference at thermopair the two poles of the earth; look into corresponding thermocouple indexing table or connect secondary control or indicating instrument, read the temperature of measured medium or directly make control usefulness.This existing thermopair can't be accomplished inner sealing, and armoured thermocouple can't be used in thermometric under the high temperature, and therefore existing thermopair can not be used under the occasion that existing very high temperature guarantees to seal again and use.
Summary of the invention
The purpose of this utility model just provide a kind of can not only be in high-temperature burner hearth thermometric and can guarantee the burner hearth thermopair of inner sealing performance.
For achieving the above object; technical solution adopted in the utility model is: a kind of burner hearth thermopair; it comprises high temperature resistant outside protective case and is contained in the interior assembled temperature element of high temperature resistant outside protective case; the assembled temperature element is contained in the high temperature resistant outside protective case; assembled temperature element and an armored temperature element are welded, and armored temperature element outside adds protection tube.
Compared with prior art, the utility model adopts armoured thermocouple to add the sealing ferrule assemblies, and the protective casing screw thread top on connecting screw internal taper hole and the flange seals with pyramidal structure.When measuring very high temperature; after the long-term use of outer protection tube leakage is arranged slightly even also guaranteed; ferrule assemblies and pyramidal structure can guarantee still that the burner hearth gas inside can not leak in the external environment condition and go, thereby prolonged the serviceable life of thermopair, and increased reliability and security.
Description of drawings
Accompanying drawing is the structural representation of the utility model burner hearth thermopair
Embodiment
The utility model is described in more detail below in conjunction with drawings and Examples.
Burner hearth thermopair shown in the drawings is to be linked together by connecting screw 4 by assembled temperature element 5 and armored temperature element 2; and armored temperature element 5 is soldered to connecting screw 4 with fixing and sealing; termination 7 is fixed and lead-in wire from armored temperature element 5 by last protection tube 6; assembled temperature element 1 is fixed in the outside protective case 2 by connecting screw 4; connecting screw 4 internal taper holes and contact position, outside protective case 2 top form cone seal; outside protective case 2 is soldered to technology side coupling arrangement 3; technology side coupling arrangement 3 is connected on the burner hearth interface; outside protective case 2 lower ends place the burner hearth measured medium; by outside protective case 2 with heat transferred assembled temperature element 1; form the temperature difference at assembled temperature element 1 end point for measuring temperature and thermocouple cold junction, thereby in output of thermocouple cold junction the two poles of the earth and the corresponding thermoelectrical potential of burner hearth measured medium temperature.
Also be equipped with connecting screw 4 between last protection tube 6 and the outer protection tube 2, the solder joint of assembled temperature element 1 and armored temperature element 5 is positioned at connecting screw 4.
Outside protective case 2 adopts pyramidal structure to match with connecting screw 4.
