Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described mount pad body exterior can be fixed by clip or engagement thread.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described cap nut side is supporting is provided with socket.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described sealing gasket is made up of dimethyl silicone rubber.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described mount pad body is connected by the latch be inserted in cotter way with gland.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described guide thimble is stainless steel tube.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described mount pad body and guide thimble weld together.
The present invention compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, vacuum heat treatment furnace the installation of TC seat of the present invention, described in be fixed with the mount pad body of guide thimble, mainly through the various ways such as clip, screw thread by thermocouple and be fixed on body of heater; In the hole, large footpath of intracavity posterior end, sealing gasket and gland are housed successively, gland contacts with the outer face of sealing gasket, and wherein sealing gasket mainly seals, and gland plays crush seal pad and deforms; Described mount pad body is connected by the latch be inserted in cotter way with gland, stops gland and sealing gasket to rotate with cap nut and is twisted off by thermo wires; Gland opposite side is equipped with cap nut, and cap nut is connected to the outboard end of mount pad body, and cap nut is convenient to promote gland and is moved sealing gasket is out of shape, thus wraps thermocouple thermo wires periphery and be adjacent to mount pad inner body wall; Cap nut side is supporting is provided with socket, ensure that thermocouple thermo wires can reliably be connected with compensating wire, and does not damage by pulling of compensating wire.In a word, the present invention is easy to loading and unloading, sealing is reliable, economic security, is applicable to promoting the use of of vacuum heat treatment furnace the installation of TC.
