High-strength high-gas-tightness quick-connecting type temperature measuring feed device

The invention discloses a high-strength high-gas-tightness quick-connecting type temperature measuring feed device which is a device for connecting a temperature measuring thermocouple with a temperature measuring instrument when being used for measuring temperature uniformity of a vacuum furnace and a hot pressure tank. The device is fixed on an equipment tank body through thread connection, so that good gas tightness is enabled to be formed during temperature measurement; the furnace body part is connected with the temperature measuring thermocouple, and an external furnace part is connected with the temperature measuring instrument. The high-strength high-gas-tightness quick-connecting type temperature measuring feed device consists of a threaded quick joint [1], a thermocouple connecting wire [2], a normal-temperature thermocouple plug [3], a high-temperature-resistant thermocouple plug [4] and isolated sealing stuffing [5]. The high-strength high-gas-tightness quick-connecting type temperature measuring feed device can be used for conveniently and quickly connecting temperature measuring thermocouple with the temperature measuring instrument, precisely measuring the temperature in the vacuum furnace and a hot pressure tank chamber, difficultly causes gas leakage on joint, and is high in product strength and good in reliability.
