Abstract
The utility model discloses a combined double-core thermocouple of a vacuum sintering furnace, which comprises a sealing gasket, flanges, terminals, thermocouple wires, threaded holes and a protective sleeve. The two thermocouple wires simultaneously measure the temperature. The combined double-core thermocouple of the vacuum sintering furnace overcomes a defect that the vacuum sintering furnace cannot operate normally after one thermocouple wire breaks. Long service life of the vacuum sintering furnace and heating elements is ensured. Use efficiency of the equipment is improved. The combined double-core thermocouple of the vacuum sintering furnace is suitable for various kinds of vacuum sintering equipment.
Description
Technical field
The utility model relates to man-made diamond powder body material vacuum-sintering field, more specifically relates to a kind of composite vacuum sintering furnace combined type twin-core thermopair, is applicable to various vacuum-sintering equipment.
Background technology

The single core thermopair of tradition is owing at high temperature working for a long time, and the life-span is shorter, once there is disconnected even phenomenon, temperature control instrument is displays temperature normally, causes vacuum sintering furnace cisco unity malfunction.Thermopair is the main element of transmission temperature signal, sintering furnace must waiting temperature be down to 40 ℃ just can load onto new thermopair, then restarts sintering, power consumption consuming time, affect vacuum-sintering equipment and powder-product quality, the utility model designs for above deficiency just.
Summary of the invention
The purpose of this utility model has been to provide a kind of composite vacuum sintering furnace twin-core thermopair.Its novelty simple in structure, easy to use, greatly improve the Homes Using TV of vacuum sintering furnace.In the situation that blowing a thermocouple wire, another group thermopair can continue to use, can not cause body of heater to burn out because of temperature control, guarantee that vacuum sintering furnace normally works, do not affect normal production, guaranteed the serviceable life of vacuum sintering furnace and the serviceable life of heating element, the blow-on rate of vacuum drying oven reaches 95% simultaneously, and product percent of pass reaches 99%.
To achieve these goals, the utility model adopts following technical measures:
A kind of composite vacuum sintering furnace twin-core thermopair, comprise sealing gasket, ring flange, connection terminal, thermocouple wire, ring flange comprises ring flange A, ring flange B and ring flange C, the chimeric sealing gasket in ring flange A two sides adjacent with ring flange C, connection terminal comprises connection terminal a+, connection terminal a-, connection terminal b+ and connection terminal b-, connection terminal is through sealing gasket center, and fixed by sealing gasket, the outside signal wire that connects of connection terminal, both positive and negative polarity thermocouple wire corresponding to the inner connection of connection terminal is thermocouple wire a+, thermocouple wire a-, thermocouple wire b+ and thermocouple wire b-, thermocouple wire is provided with protective casing.On ring flange A, ring flange B and ring flange C, be equipped with threaded hole, the threaded hole 5 on ring flange C is arranged on the body of heater measured hole of vacuum sintering furnace by screw.Connection terminal a+ is connected with the positive wire of temperature control instrument with connection terminal b+, and connection terminal a-is connected with the cathode conductor of temperature control instrument with connection terminal b-.Thermocouple wire both positive and negative polarity a+, a-are connected to one group of thermopair with connection terminal a+, a-respectively, and thermocouple wire both positive and negative polarity b+, b-are connected to other one group of thermopair with connection terminal b+, b-respectively, two groups of thermopairs thermometric simultaneously.
The beneficial effects of the utility model are, strengthen the utilization factor of thermocouple wire, the same point for measuring temperature of vacuum sintering furnace has two groups of thermocouple wires thermometric simultaneously, increase measurement accuracy, there are two groups of thermocouple wires, overcome and resolve the drawback that one group of thermocouple wire final vacuum sintering furnace can not normally be produced, thereby the utilization rate of raising equipment improves the Homes Using TV of vacuum sintering furnace and the qualification rate of product simultaneously.
