Description
Technical field
The invention belongs to thermocouple assembly technical field, relate in particular to a kind of vacuum heat treatment furnace the installation of TC seat.
Background technology
Vacuum heat treatment furnace, the heating furnace of heat treatment is carried out as a kind of be placed under vacuum environment by workpiece, function is to improve the surface quality of workpiece and mechanical performance, is one of advanced Technology for Heating Processing of using of current machinery manufacturing industry, is especially widely used in aerospace industry field.
One of vacuum drying oven key technical index is exactly that burner hearth slip (or claiming Pressure Rise Rate) is less than certain numerical value.If vacuum drying oven burner hearth seals bad, leaking in processing workpiece fabrication, the lighter causes heat treatment of workpieces quality problems, and serious meeting causes burner hearth to burn.Vacuum heat treatment process, in burner hearth, air is clean by basic pump drainage, thus ensure that workpiece not oxidized corrosion and other dirt contamination in whole heating process；And some metal materials needs quickly to cool down after heating, in order to ensure that workpiece is in the most not oxidized corrosion of cooling procedure and pollution, then by being filled with high-purity hydrogen, nitrogen or argon to burner hearth and making it flow in burner hearth quickly to cool down, the highest cooling capacity to workpiece of gas pressure intensity being filled with is the strongest.Therefore, vacuum drying oven burner hearth needs to stand the alternating action of malleation-negative pressure during processing workpiece, easily makes the seal failure in pertusate place on furnace wall cause burner hearth to leak.
The Control for Kiln Temperature of vacuum drying oven heating uses thermocouple to measure fire box temperature, to carry out record and the control of process furnace temperature.Thermocouple is connected through hearth wall with outside temperature indicator, monitor, controller, and the installation at thermocouple and furnace wall perforation must assure that sealing, and can stand the impact of n-anti-differential pressure of atmospheric pressure.In prior art, the mounting means of thermocouple is of all kinds, and the problem existed mainly has: seal failure easily occur under burner hearth positive-negative pressure alternating action；Installation and removal inconvenience, and it is easily damaged thermo wires during installation and removal；Carry out sealing with binding agents such as resins and make thermocouple dismounting after resin be difficult to remove, it is impossible to use again；If just scrapping after using once with the thermocouple thermo wires of the precious metal manufacture such as platinum, rhodium, cost is the highest.
Summary of the invention
It is an object of the invention to overcome disadvantages mentioned above and provide a kind of easy to loading and unloading, seal reliable, the vacuum heat treatment furnace the installation of TC seat of economic security.
The object of the invention and solve its technical problem underlying and realize by the following technical solutions:
The vacuum heat treatment furnace of present invention the installation of TC seat, including mounting seat body, sealing gasket, cap nut, wherein: mounting seat body is axially disposed inner chamber, inner chamber is made up of the diameter holes of leading portion and the hole, big footpath of back segment, connect in the middle of diameter holes and hole, big footpath and have bellmouth, mounting seat body is fixedly arranged at the front end with guide thimble, the hole, big footpath of intracavity posterior end is sequentially arranged with sealing gasket and gland, gland contacts with the outer face of sealing gasket, gland opposite side is equipped with cap nut, cap nut is connected to the outboard end of mounting seat body, without being torsionally connected between mounting seat body and gland.
Above-mentioned vacuum heat treatment furnace the installation of TC seat, wherein: described mounting seat 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 mounting seat body is connected by the latch being 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 mounting seat body welds together with guide thimble.
The present invention compared with the existing technology has clear advantage and beneficial effect.From above technical scheme, the vacuum heat treatment furnace of present invention the installation of TC seat, described in be fixed with the mounting seat body of guide thimble, mainly and be fixed on thermocouple on body of heater by the various ways such as clip, screw thread；Being sequentially arranged with sealing gasket and gland in the hole, big footpath of intracavity posterior end, gland contacts with the outer face of sealing gasket, and wherein sealing gasket acts primarily as sealing function, and gland plays the effect that crush seal pad deforms；Described mounting seat body is connected by the latch being 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 mounting seat body, and cap nut is easy to promote gland to move makes sealing gasket deform, thus wraps thermocouple thermo wires periphery and be adjacent to mounting seat inner body wall；Cap nut side is supporting is provided with socket, it is ensured that thermocouple thermo wires can be reliably connected with compensating wire, and do not pulled by compensating wire and damage.In a word, the present invention is easy to loading and unloading, sealing is reliable, economic security, is suitable for promoting the use of of vacuum heat treatment furnace the installation of TC.
