Abstract
The utility model relates to a corrosion-resistant thermocouple or thermal resistor, include the wire body and fix the binding post in wire body one end, the one end pressure equipment that binding post was kept away from to the wire body has the stainless steel protection tube, wire body and stainless steel protection tube overcoat have the polytetrafluoroethylene sleeve pipe, and polytetrafluoroethylene sleeve pipe head does sealed the processing. This corrosion-resistant thermocouple or thermal resistance's stainless steel protection tube adopts the mode of pressure equipment to fix on the wire body, for modes such as threaded connection in the past, the structure is simpler, and processing is more convenient, simultaneously because at wire body and stainless steel protection tube outer parcel polytetrafluoroethylene sleeve pipe, can adapt to acid-base environment, has better corrosion-resistant effect, has improved thermocouple or thermal resistance's life greatly.
Description
Technical Field
The utility model relates to a thermocouple or thermal resistance technical field especially relate to a corrosion-resistant thermocouple or thermal resistance.
Background
In order to adapt to acid-base environments, corrosion-resistant layers are coated on the surfaces of existing ordinary thermocouples, armored thermocouples or thermal resistors, the structures and the processing processes of the existing ordinary thermocouples are complex, the manufacturing cost is high, in addition, in the coating process, wires need to be soaked in solutions, the insulation layers on the surfaces of the wires are prone to corrosion, and the coatings are prone to falling off after being used for a long time, so that the service lives of the thermocouples or the thermal resistors are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, simple in manufacturing process, low in manufacturing cost, long service life's corrosion-resistant thermocouple or thermal resistance.
The utility model discloses a realize through following technical scheme: the utility model provides a corrosion-resistant thermocouple or thermal resistor, includes the wire body and fixes the binding post in wire body one end, the stainless steel protection tube is pressed fit with to the wire body one end of keeping away from binding post, wire body and stainless steel protection tube overcoat have the polytetrafluoroethylene sleeve pipe, and polytetrafluoroethylene sleeve pipe head does sealed treatment.
As only one end of the lead body close to the stainless steel protection pipe is soaked in the acid-base solution, in order to further reduce the cost, the part of the lead body close to the stainless steel protection pipe is wrapped by the polytetrafluoroethylene sleeve.
Further, in order to fix the polytetrafluoroethylene sleeve and the local part of the lead body, a heat-shrinkable sleeve is wrapped outside one end, far away from the stainless steel protection tube, of the polytetrafluoroethylene sleeve.
In order to facilitate the observation of the internal structure, the polytetrafluoroethylene sleeve is a transparent tube.
The utility model has the advantages that: this corrosion-resistant thermocouple or thermal resistance's stainless steel protection tube adopts the mode of pressure equipment to fix on the wire body, for modes such as threaded connection in the past, the structure is simpler, and processing is more convenient, simultaneously because at wire body and stainless steel protection tube outer parcel polytetrafluoroethylene sleeve pipe, can adapt to acid-base environment, has better corrosion-resistant effect, has improved thermocouple or thermal resistance's life greatly.
Drawings
Fig. 1 is a schematic structural diagram of a corrosion-resistant thermocouple or thermal resistor according to the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
As shown in fig. 1, the corrosion-resistant thermocouple or thermal resistor includes a lead body 1 and two connection terminals 2 fixed at one end (bottom end in the figure) of the lead body 1, the joint of the connection terminals 2 and the end of the lead body 1 is fixed by a heat-shrinkable tube 3, a stainless steel protection tube 4 is press-fitted at one end (top end in the figure) of the lead body 1 far from the connection terminals 2, the stainless steel protection tube 4 is directly fixed with the lead body 1 by press-fitting equipment, a polytetrafluoroethylene sleeve 5 is sleeved outside the lead body 1 and the stainless steel protection tube 4, and the head of the polytetrafluoroethylene sleeve 5 is sealed, i.e., the polytetrafluoroethylene sleeve 5 encapsulates the stainless steel protection tube 4, so as to prevent the stainless steel protection tube 4 from contacting with acid and alkali liquids, and the polytetrafluoroethylene sleeve 5 is a transparent tube.
The whole lead body 1 is not wrapped by the polytetrafluoroethylene sleeve 5, but only the part close to the stainless steel protection tube 4 (i.e. the part immersed in the acid-base solution) is wrapped by the polytetrafluoroethylene sleeve 5. In addition, a heat-shrinkable sleeve 6 is wrapped outside one end, far away from the stainless steel protection tube 4, of the polytetrafluoroethylene sleeve 5, so that the polytetrafluoroethylene sleeve 5 and the lead body 1 are relatively fixed.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
