Abstract
The utility model provides a temperature measuring simulating and insulation sealing device for ionitriding. An armored thermocouple goes through a central hole of a polytetrafluoroethylene lower sealing sleeve, and is cased with an O-shaped sealing ring and then cased into a tapered polytetrafluoroethylene upper sealing sleeve. An O-shaped sealing ring is filled between the upper sealing sleeve and a casing pipe and is screwed with a gland nut. Then, an O-shaped sealing ring is used for sealing between the casing pipe and a furnace body pedestal. The casing pipe goes through the furnace body pedestal and a lower cathode disc and is fixed on the lower cathode disc with a gland nut and a sealing gasket. A ceramic tube and a mica sleeve are sleeved in from top down. And a cap is covered at last. The cap can shield components on the lower cathode disc and in the cap, thereby avoiding the temperature measuring precision to be influenced by arc strike caused by poor contact.
Description
Technical field
The utility model belongs to thermal treatment simulated temperature measurement insulated enclosure technical field, particularly a kind of deep-well ionic nitriding simulated temperature measurement insulation seal device.
Background technology
The simulated temperature measurement device is in order more accurately to measure and control ionic nitriding workpiece technological temperature; Tradition photoelectricity thermometric or range estimation temperature deviation are bigger, and subjectivity is strong, and the control difficulty is big; Simulated temperature measurement device in the past is because of the imperfection of design; Can not essence solve anode and cathode insulation and deep-well stove impermeability problem, can't realize that the long pole ionic nitriding is temperature automatically controlled, limit the demanding stainless steel part product ion of impermeability nitriding process effect is implemented.
Summary of the invention
The purpose of the utility model is exactly in order to overcome the deficiency of original technology, a kind of long pole ionic nitriding simulated temperature measurement insulation seal device to be provided.
The technical scheme of the utility model is achieved in that armoured thermocouple passes the teflon lower sleeve gasket center pit of wearing gland nut and having tapering, puts the O RunddichtringO again, is inserted in the teflon upper sleeve gasket of band tapering then; Pad O RunddichtringO between upper sleeve gasket and the sleeve pipe; Screw with gland nut, then, seal with the O RunddichtringO between sleeve pipe and the base of furnace body; Sleeve pipe passes base of furnace body and following cathode disc; Be fixed on down on the cathode disc with gland nut and packing washer, be inserted in porcelain tube and mica cover from top to bottom, cover housing at last.Housing can shield down interior each element of housing on the cathode disc, and stopping to beat arc because of loose contact influences temperature measurement accuracy.
The utility model has the advantages that simple and compact for structure, stable and reliable for performance, economical and practical.

Fig. 1 is the utility model structural representation.
1. housings among the figure, 2. gland nut one, 3. mica cover, 4. armoured thermocouple, 5. porcelain tube, 6. sleeve pipe, 7. upper sleeve gasket, 8. gland nut two, 9. lower sleeve gasket, 10. packing washer, 11.O RunddichtringO, 12. base of furnace body, 13. times cathode discs.
Embodiment
Before the ionic nitriding blow-on, armoured thermocouple (4) passes teflon lower sleeve gasket (9) center pit of wearing gland nut one (2) and having tapering, puts O RunddichtringO (11) again; Be inserted in the teflon upper sleeve gasket (7) of band tapering then, pad O RunddichtringO (11) is screwed with gland nut two (8) between upper sleeve gasket (7) and the sleeve pipe (6); Then; With O RunddichtringO (11) sealing, sleeve pipe (6) passes base of furnace body (12) and following cathode disc (13), is fixed on down on the cathode disc (13) with gland nut one (2) and packing washer (10) between sleeve pipe (6) and the base of furnace body (12); Be inserted in porcelain tube (5) and mica cover (3) from top to bottom, cover housing (1) at last.Housing can shield down interior each element of housing on the cathode disc, and stopping to beat arc because of loose contact influences temperature measurement accuracy.Between this device gland nut and the following cathode disc, be plane contact between upper sleeve gasket and the sleeve pipe and between sleeve pipe and the body of heater; Adopt the sealing of packing washer or O RunddichtringO all can easily solve sealing problem; Key is must leave the gap thermopair between armoured thermocouple and the teflon seal cover center pit can pass; Because of the upper-lower seal cover has tapering; Middle O RunddichtringO has a horizontal component of extruding inward in fastening process, more fully ensured the sealing between thermopair and the body of heater reliably.
In the ionic nitriding process, according to the size of batch, behind the heat tracing certain hour, temperature is promptly consistent with workpiece temperature in the housing, can realize accurate thermometric and robotization control through the simulated temperature measurement device.
Claims (1)
1. ionic nitriding simulated temperature measurement insulation seal device; It is characterized in that: armoured thermocouple (4) passes teflon lower sleeve gasket (9) center pit of wearing gland nut one (2) and having tapering; Put O RunddichtringO (11) again, be inserted in the teflon upper sleeve gasket (7) of band tapering then, pad O RunddichtringO (11) between upper sleeve gasket (7) and the sleeve pipe (6); Screw with gland nut two (8); Then, with O RunddichtringO (11) sealing, sleeve pipe (6) passes base of furnace body (12) and following cathode disc (13) between sleeve pipe (6) and the base of furnace body (12); Be fixed on down on the cathode disc (13) with gland nut (1) and packing washer (10), be inserted in the cover (1) that closes the lid behind porcelain tube (5) and the mica cover (3) from top to bottom.
