The thermocouple preparing device comprises a voltage regulator and a container, the both input ends of the primary coil of the voltage regulator are connected with an alternating current power supply through a switch, two output ends of the secondary coil of the voltage regulator are respectively connected with the non pre-welded end of the thermocouple requiring welding and a tin film electrode, and the tin film electrode immerges into the container with noncombustible fuel, wherein, the tin film electrode comprises a metal framework made of conductive metal materials and tin foil films attaching closely to the metal framework, and one end of the output ends of the secondary coil of the voltage regulator is connected with the metal framework.
Description
(1) technical field
The utility model relates to the device of making thermocouple.
(2) background technology
In the prior art, arc welding, argon arc welding, gas welding, carbon dust welding, salt solution welding, mercury welding etc. are extensively adopted in the manufacturing of thermocouple.Many manufacture methods all have weak point: wherein arc-welding process is prone to the carburizing contamination on the electrode near pad reaches; The cost of equipment costliness that the argon arc welding connection is required, inapplicable common lab is used; Though gas welding is convenient, equipment manufacturing cost is lower, operation is difficult to grasp, and it and carbon dust weld and all easily cause the thermal cross brittle failure; Salt solution welding and mercury welding equipment are simple, cheap, but the salt solution welding has selectivity to electrode material, can not adopt the metal that electrolysis can take place in sodium chloride solution; When water silver soldering connects,, unfavorable to health because there is vapo(u)rability in mercury vapor.
(3) summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of device for preparing thermocouple.This device is cheap, and it is wide to adapt to the electrode material scope, can avoid thermocouple defectives such as contamination, brittle failure to occur.The simple and reliable process of this device, be convenient to the operation, health is not had harm.
The technical solution of the utility model realizes as follows: the device of preparation thermocouple, it comprises voltage regulator, container, two inputs of the primary coil of voltage regulator connect AC power through switch, its design feature is, two outputs of the secondary coil of voltage regulator connect the non-pre-welding end and the tin membrane electrode of the thermocouple that needs welding respectively, and the tin membrane electrode immerses and is equipped with in the container of non-easy fuel oil.
According to above-mentioned technical scheme, the tin membrane electrode is to be made of the metal framework of conductive metallic material making and the tinfoil film that closely is attached on the metal framework, and an end of the secondary coil output of voltage regulator is connected with metal framework.
The utility model makes that the thermocouple welding equipment is simple in structure owing to adopted above-mentioned device, and is cheap.Because the thermocouple welding is to carry out in having the container of non-easy fuel oil, therefore avoided thermocouple defectives such as contamination, brittle failure to occur again.Have simple to operate, the characteristics of good reliability.The thermocouple high conformity of making, and smooth surface have metallic luster, its precision reaches ± and 0.1 ℃, can be used as the secondary standard thermometer and use, be applicable to that the galvanic couple wire diameter is the cheap metal thermocouple making of 0.03mm to 0.5mm, has the value of extensively promoting the use of.
