Abstract
The invention relates to a thermocouple leading device which comprises a thermocouple connecting base, wherein the lower end of the thermocouple connecting base is provided with a thermocouple, an insulating base is arranged at the upper end of the thermocouple connecting base, and a wiring pole is arranged on the insulating base. The thermocouple leading device is characterized in that a flange cover and a protective cover fixed on the flange cover are covered on the insulating base, and the thermocouple is fixed at the lower end of the thermocouple connecting base through a compression screw and sealed by a seal pad and a gasket; a second O-shaped seal ring for sealing is arranged between the insulating base and the thermocouple connecting base, and a first O-shaped seal ring is arranged on the contact surface of the thermocouple connecting base with a furnace body. The thermocouple connecting base is respectively fixed with the furnace body and the flange cover by a hexagon bolt, a first hexagon nut and a first gasket. The thermocouple is a twin platinum-rhodium10-platinum thermocouple. With the thermocouple leading device, better seal property can be obtained, and the seal problem can be better solved.
Description
Technical field
The present invention relates to a kind of thermopair ejector, especially a kind of thermopair ejector that is used for industrial furnace.
Background technology
The various thermopairs of widespread use carry out the measuring and controlling temp operation in the commercial production, and as at heat treatment industry, temperature must obtain accurately effectively control as a key factor in producing.Present thermopair is basically all through opening the mounting means that mounting hole directly inserts thermopair furnace chamber on the furnace wall; This mounting means can relate to the problem of sealing; Present more employing individual layer hermetically-sealed construction; But have in the container of negative pressure or malleation at some, find that gas leak phenomenon to a certain degree can appear in this sealing means under the certain situation, the operate as normal that influences equipment is used.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of thermopair ejector is provided, the Seal Design raising sealing property through bilayer reduces the generation of gas leak phenomenon.
According to technical scheme provided by the invention, said thermopair ejector comprises the thermopair Connection Block, in the lower end of thermopair Connection Block thermopair is installed, and in the upper end of thermopair Connection Block insulating base is set, installation connection post on insulating base; Characteristic is: on said insulating base, be covered with blind flange and be fixed on the protective cover on the blind flange, said thermopair is fixed on the lower end of thermopair Connection Block through housing screw, and passes through sealing gasket and pressure pad sealing; Between said insulating base and thermopair Connection Block, be provided with the 2nd O RunddichtringO that is used to seal, the surface that said thermopair Connection Block contacts with body of heater is provided with an O RunddichtringO.
Said thermopair Connection Block is fixed with body of heater, blind flange respectively through hex bolts, first hexagonal nut and first plain washer.
Said thermopair can also can be similar thermopair for two platinum rhodium 10-platinum thermocouples.
Said protective cover is fixed on the blind flange through Cross Recess Head Screw.
Said binding post is installed on the insulating base through second hexagonal nut and second plain washer.
The present invention has the following advantages:
(1) through the double-layer seal design, can obtain better sealing property;
(2) with respect to individual layer sealing, (as 1300 ℃ with upper furnace body) can be good at solving sealing problem on some equipment higher to seal request.
