Description
Technical field
The utility model relates to a kind of auxiliary manufacturing device of electric heater, specifically a kind of electric heating tube fills silicone oil dress
It sets.
Background technique
Electric heating tube is that electric heating wire is packed into seamless steel pipe as the core component as electric heater, space part
Divide after being filled with the magnesia powder of Thermal conductivity and insulation performance made of the draw.Magnesia powder is located at resistance wire and tube wall
Between, for the insulation between resistance wire and tube wall.Meanwhile magnesia powder has good heating conduction again.When electric current passes through
When high temperature resistance silk, the heat of generation passes through crystal magnesium oxide powder to heating tube diffusion into the surface, then is transmitted to the air being heated
In, to achieve the purpose that heating.But magnesia is easy to absorb the aqueous vapor in environment, so that magnesia powder is made moist, electric insulation
Performance decline, electrothermal tube leak electricity and fail, for this reason, it may be necessary to using joint filling material by electric heating tube end opposing seal, exclusion of water
Point.
Current most common three kinds of joint filling material paint films class, epoxy resin and silicone oil have the shortcomings that different degrees of.
Paint film class is to use one layer or several layers of paint films as joint filling material, the disadvantage is that intensity is low, with the presence of pin hole, is easy aging, for a long time
Cracking can be generated after use, need to seal again.Its heatproof of epoxy resin material is not high, and only 150 DEG C or so, electricity before sealing
The insulation performance of heating tube must be good, otherwise, after epoxy resin sealing hardening, then does over again highly difficult.Silicone oil is used as electric heating
Channel closure material is most commonly used, but since silicone oil is in a liquid state, and after filling cannot compared with deeper into magnesia powder, because
And be easy gradually to reveal after filling sealing a period of time, sealing performance also declines therewith.
Summary of the invention
The silicone oil that electric heating tube end can be made to inject technical problem to be solved by the utility model is to provide one kind is more preferable
Enter magnesia powder, reduce silicone oil leakage, to improve electric heating composite pipe tightness, and apparatus structure is simple, electricity easy to use
Heating tube fills silicone oil device.
It includes a sealing shroud that the electric heating tube of the utility model, which fills silicone oil device, and sealing shroud rear end is connected by external screw thread
The clamping nut for having centre bore is connect, clamping nut and the diameter of bore of sealing shroud and the electric heating pipe outside diameter of installation to be added are matched
Close, seal groove be set between the rear end face of sealing shroud on the inside of clamping nut, and be mounted with sealing ring, by clamping nut with
Sealing external threading is put into, can be squeezed sealing ring and is deformed inward sealing ring and contact sealing with electric heating pipe outer wall, realization sealing shroud
The sealing of rear end；Sealing shroud inner hole leading portion and the socket of inlet suction port back segment cooperate, and by before between mating surface
Sealing ring sealing；Threaded hole is arranged in inlet suction port rear end, the power supply eduction rod end that can be stretched out with electric heating tube hub to be installed
Portion is threadedly engaged connection；Inlet suction port front end inlet is connected by screw thread with the suction nozzle for being used to connect compressed gas source, air inlet
The inlet channel for linking up front end inlet and sealing shroud inner cavity is provided in joint matrix.
The suction nozzle front end connects pressure reducing valve by air inlet pipeline, and connects compressed gas source by pressure reducing valve.
Pressure gauge is also connected on the air inlet pipeline.
The invention has the advantages that 1, can be by sealed pressure structure, by the oxygen of the silicone oil indentation leading portion of electrothermal tube leading portion
Change in magnesium powder, silicone oil is made to go deep into magnesia powder, thus is not easy to reveal；2, its structure is simple, few with material, save the cost；3,
Whole to use connection tubular type, pressure is directly transmitted, and without the pressure loss, can control pressure size by pressure reducing valve；4, silicone oil pressure
Fashionable sealed reliable, is able to maintain pressure state, and No leakage can voluntarily control the dwell time；5, whole device and electric heating tube
Eduction rod is threadably secured, and device is integrally detached from electric heating tube when pressure can be prevented excessive, and use is safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of the utility model use state.
Specific embodiment
As shown in Figure 1, it includes a sealing shroud 1 that the electric heating tube of the utility model embodiment, which fills silicone oil device, sealing
Cover rear end and one clamping nut 2 for having centre bore connected by external screw thread, the diameter of bore of clamping nut and sealing shroud and to
Add the electrothermal tube G major diameter fit (electric heating my humble opinion Fig. 2) of installation, is arranged between 2 inside of clamping nut and the rear end face of sealing shroud 1 close
Seal slot, and be mounted with sealing ring 3, by the cooperation precession of clamping nut and sealing external threading, can squeeze sealing ring make it is close
Seal 3 is deformed inward and contacts sealing with electric heating pipe outer wall, realizes the sealing of sealing shroud rear end；1 inner hole leading portion of sealing shroud and one
The socket cooperation of 4 back segment of inlet suction port, and sealed by the preceding sealing ring between mating surface；Spiral shell is arranged in 4 rear end of inlet suction port
Pit, power supply eduction rod B (power supply eduction rod the is shown in Fig. 2) end that can be stretched out with electric heating tube hub to be installed are threadedly engaged
Connection；4 front end inlet of inlet suction port is connected by screw thread with the suction nozzle 5 for being used to connect compressed gas source, in 4 matrix of inlet suction port
It is provided with the inlet channel 6 for linking up front end inlet and sealing shroud inner cavity.
As shown in Fig. 2, 5 front end of suction nozzle connects pressure reducing valve 8 by air inlet pipeline 7, and passes through decompression in its course of work
Valve connects compressed gas source.Pressure gauge 9 is also connected on air inlet pipeline 7, for monitoring air pressure.
Its course of work is as follows: first will be in the front end electrothermal tube G for enclosing resistance wire, power supply eduction rod and magnesia powder
Silicone oil O is injected in one section of blank pipe, electrothermal tube leading portion is then inserted into sealing shroud 1, by the screw thread of the front end power supply eduction rod B and air inlet
Connector 4 is cooperatively connected, then screws clamping nut 2, by sealing ring 3 by sealing shroud back-end sealing, then opens on air inlet pipeline
Pressure reducing valve, allow compressed air into sealing shroud and electrothermal tube, by silicone oil indentation back segment magnesia powder in.
