Description

The hot melt welded tube mill of duplicate protection

Technical field

The utility model relates to a kind of plastic pipe sweat soldering instrument, the interconnective hot melt welded tube mill of particularly a kind of small-bore plastic pipe.

Background technology

Plurality of advantages such as that plastic pipe has is in light weight, corrosion-resistant, compressive resistance is high, safe and sanitary, resistance to water-flow are little, long service life, the laborsaving convenience of installation; Recently plastic pipe is developed rapidly, is widely used in industries such as water supply pipe, gas piping, wireway.The sweat soldering of hot melt welded tube mill is generally adopted in the connection of present small-bore plastic pipe; Exactly with interconnective tube surface and the fluid that becomes viscous after the heating mould of heating on the aluminium sheet contacts hot melt; The surperficial socket of fusion is forced together, and polymer molecule moves under the effect of heat and pressure, interts each other and coils; Produce bonding force; The cooling back forms firm solder side, and weld strength depends on each other interspersed coiling degree between the solder side, and the quality of welding quality depends primarily on hot melting temperature.But there is following weak point in the hot melt welded tube mill that uses now: the one, and the heating aluminium sheet is connected unreasonable with left and right sides housing; The heat of aluminium sheet of will generating heat easily is delivered on the housing of the left and right sides; Cause left and right sides housing heating, aging, hot, the temperature controller cisco unity malfunction causes the welding quality of tubing unstable at last; Service life is short, inefficiency.The 2nd, because the hot melt welded tube mill is through temperature controller control temperature; Main circuit does not have other any safeguard measure; If transship, reasons such as overheated, short circuit, temperature controller damage all can cause the hot melt welded tube mill to damage, even cause accident of power supply, bring great unsafe factor to electric power system.The 3rd, because left and right sides case temperature is too high, often water cooling, housing seal weak effect in the left and right sides causes the hot melt welded tube mill to be intake easily, and there is serious potential safety hazard in the use that can't ensure safety.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have desirable product to emerge so far.

Summary of the invention

For overcoming the existing existing above-mentioned deficiency of hot melt welded tube mill, the purpose of the utility model provide a kind of simple and reasonable, good heat-insulation effect, stable temperature control, safe and reliable, welding quality good and have the hot melt welded tube mill of overload, overheated duplicate protection.

The utility model solves the problems of the technologies described above the technical scheme that is adopted; It comprises heating aluminium sheet, bracing frame, left and right sides housing, flexible glue handle, temperature sensor, temperature controller, temperature controller knob, indicator lamp, water proof switch, heat-sensitive automatic circuit-breaker and main fuse; Be provided with heat-generating pipe in the heating aluminium sheet; The lead-out wire of heat-generating pipe is provided with the insulation heat shield; The flexible glue handle is fixed on the fixed handle of left and right sides housing, is fixed on the described heating aluminium sheet fixedly on the square tube, and fixedly square tube is removably disposed on the bracing frame; Left and right sides housing is fixedly connected with fixing square tube through thermal insulation barriers, and main circuit is in series by heat-generating pipe, heat-sensitive automatic circuit-breaker, temperature controller, water proof switch and main fuse.

Described left and right sides housing is provided with the waterproof grommet with the sealing of heat-generating pipe lead-out wire.

Described left and right sides housing joint is provided with the double stopper that cooperatively interacts.

After adopting said structure; With prior art following advantage and effect are arranged relatively: the one, because left and right sides housing is connected with fixing square tube through thermal insulation barriers; Heat-generating pipe and main circuit are flexible coupling, and good heat-insulation effect can not cause the temperature controller cisco unity malfunction because of left and right sides housing is overheated; Heating and temperature control is stable, thereby has guaranteed the welding quality of tubing effectively.The 2nd, owing on main circuit, increased heat-sensitive automatic circuit-breaker and main fuse, main circuit has overload, overheated duplicate protection, can not cause welded tube mill to damage, and more can not cause the chain accident of electric power system, long service life.The 3rd, in order to prevent the water cooling, left and right sides housing and heat-generating pipe lead-out wire have carried out sealing and fixing, guarantee safe and reliable.The 4th, simple and reasonable, durable in use, elegant in appearance, have vast market prospect.
