Abstract
The invention relates to a vacuum sealing joint for a low-temperature tubular heating tube. The vacuum sealing joint comprises a tubular spiral heating tube, a vacuum joint, a sealing ring and compression nuts, wherein the vacuum joint is fixedly connected into an installation hole of a vacuum furnace wall; conducting ends of the tubular spiral heating tube are inserted in the vacuum joint; the vacuum joint is provided with inner conical holes, and in fit connection with outer conical tables on the tubular spiral heating tube through the inner conical holes; the sealing ring is arranged between the inner conical holes and the outer conical tables; and the tubular spiral heating tube is locked and fixed, and the sealing ring is compressed on the conducting ends of the tubular spiral heating tube through the compression nuts, so as to achieve a vacuum sealing effect. The joint enables a heating component of a vacuum furnace to be directly supplied with power of 220 V instead of being supplied with power by configuring voltage dropping equipment, thus configuration of a small vacuum furnace is simplified, and the equipment cost is reduced. Moreover, a reliable sealing structure is provided for producing the small vacuum heating furnace by virtue of the heating component for vacuum heating, and a technical support is provided for producing the small vacuum heating furnace by widely using the tubular heating tube.
Description
Technical field
The present invention relates to a kind of vacuum sealing joint for low temperature (less than 400 DEG C) vacuum furnace, especially a kind of
Vacuum furnace tubular heating pipes vacuum sealing joint.
Background technology
In the product manufacturing of low temperature (less than 400 DEG C) small internal vacuum furnace, uniform for the fire box temperature making heating
Degree improves, and can use tubular heating pipes heating element heater, and have to be lower than 80 volts yet with the voltage of heating in vacuum drying oven could not
There is vacuum discharge, be the most all that 220 volts (or three-phases 380 volts) are depressurized to less than 80 volts, as joined by configuration voltage step-down equipment
Put magnetic voltage regulator, so by the electric seal nipple of conventional vacuum of configuration on vacuum drying oven, the outer 80 volts of voltages of stove and vacuum electric
The outer contact of gas joint stove connects, in stove the joint of heating element heater just can directly and the inner contact of vacuum electrical connector be directly connected to and
There is not vacuum discharge, correspondingly to increase a decompression device expense, make the tubular heating pipes of employing 220 volts make heating element heater
It is fabricated to small-sized low temperature vaccum heat stove and becomes unrealistic because cost is the highest.Accordingly, it would be desirable to design one vacuum sealing joint, make
The contact of 220 volts is placed on outside stove and makes again tubular heating pipes ensure vacuum sealing when drawing outside vacuum drying oven, and vacuum drying oven must not leak gas, make
Tubular heating pipes electric connection had not only avoided in producer vacuum discharge but also had directly used 220 volts to power.So that tubular heating pipes
Internal heat type vacuum drying oven can be reliably used for.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low temperature tubular heating pipes vacuum sealing joint, and this joint can make
Vacuum drying oven heating element heater directly can be powered with 220 volts and power without configuring decompression device, simplifies the configuration of small size vacuum stove,
Reduce equipment cost., and make small size vacuum heating furnace for the heating element heater of heating in vacuum and provide and seal knot reliably
Structure, provides technical support for tubular heating pipes making small size vacuum heating furnace is widely used.
In order to solve above-mentioned technical problem, present invention employs following technical scheme:
A kind of low temperature tubular heating pipes vacuum sealing joint, adds heat pipe, vacuum adapter, sealing ring, compression spiral shell including tubular helical
Mother, described vacuum adapter is fixedly connected in the installing hole of vacuum furnace wall, and described tubular helical adds the conducting end of heat pipe and inserts true
In empty joint, described vacuum adapter is provided with internal tapered hole, and adds the male-tapered platform on heat pipe by internal tapered hole and tubular helical
Being connected, be provided with sealing ring between described internal tapered hole and male-tapered platform, described tubular helical adds in the conducting end of heat pipe logical
Cross the clamp nut tubular helical that is locked and add heat pipe, and compress sealing ring, reach vacuum sealing function.
Described tubular helical adds and is screwed with two clamp nuts in the conducting end of heat pipe.Described sealing ring loads in vacuum adapter
In seal groove.
Beneficial effects of the present invention:
The present invention, by installing low temperature tubular heating pipes vacuum sealing joint on furnace wall, efficiently solves conventional tubular heating
Pipe directly leads out when heating in vacuum cannot guarantee burner hearth vacuum-packed technology requirement.If only fitting by the conical surface, and arming
The sealing ring entered, due to the deviation of interior male cone (strobilus masculinus) angle processing, at most realizes insecure line contact sealing.Add sealing ring
After, after clamp nut compresses, tubular heating pipes will apply clamping load to sealing ring with the laminating of the vacuum adapter conical surface, make inside and outside
The conical surface carries out vacuum sealing by sealing ring as intermediate medium, is now converted to face seal by linear sealing, thus ensure that can
The vacuum leaned on seals.
Use the low temperature tubular heating pipes vacuum sealing joint of the present invention, be not only simple in structure, low processing cost, and
Assembling simple, stove vacuum sealing effectiveness is obvious, creates feasible for using helix heating pipe to manufacture internal heat type vacuum drying oven
