Abstract
Heater that tubular metal resonator has non -metallic pipe outward and formula of sinking connecting piece combination formula electrothermal tube of moulding plastics, the electrothermal tube comprises (7) two parts of the connecting piece combination that the tubular metal resonator has non -metallic pipe's heater (5) and the formula non -metallic material that sinks to mould plastics outward, the tubular metal resonator has non -metallic pipe heater (5) outward, is in tubular metal resonator built -in heating wire (3), and is insulating with magnesia end (4) and tubular metal resonator, and the stick is drawn in same one end in its outer adorn non -metallic pipe (9), the formula of sinking is moulded plastics connecting piece (7), adopts the preparation of non -metallic material shooting technique, and the system has installation tubular heater's hole on it, and the skew connecting piece installation central line certain distance in this hole ensures that the electrothermal tube sinks when the in -service use in the water tank, and the hole system of the connecting piece of moulding plastics (7) has step (8), has between non -metallic pipe (9) and connecting piece (7) sealing member (2).
Description
Technical field
The present invention relates to electrothermal tube, relate generally to electric heater, central heater, air source hot pump water heater,The hot-water heating systems such as solar water heater, electric boiler, water dispenser, boiler, little kitchen treasured, are immersed in waterStraight shape non-metal tubular heater and sunk type injection moulding connecting piece combined electrical heat pipe.
Background technology
The existing tubular metal electric heating element for hot-water heating system (claim tubular heater or claim electrothermal tube,Lower with), the 100%th, by technical standard GB/T23150-2008 " water heater tubular heater " orJB/T4088-1999 " daily tubular electrothermal element " produce tubular electrothermal element, be " taking metal tube as outsideShell, heating alloy are made heater, and at one end or two ends have eduction rod, load closely knit oxygen in metal tubeChange magnesium dust dielectric, to fix the element of heater; " this metal shell heating, be to soak completelyDuck in drink, after use, can scaling, reduce heating efficiency, and corrosion makes water charged after puncturing, beWorld-famous puzzle over 140 years; Application number 201520816869.3 and 201510688413.8 < non-metal electric heating unitPart>and application number 201520996947.2 and 201510860091.0<flanged or non-flanged non-metal electric heatingPipe > heating has been done to improvement, the application remakes supplementary.
Summary of the invention
The product configurations, the manufacture method that the object of the invention is existing water heater tubular heater propose newTechnical scheme.
Technical measures of the present invention are by the non-gold of straight shape at a non-metallic pipe heater of the outside of metal tube suitConnecting piece 7 two parts that belong to tubular heater 5 and the injection moulding of sunk type nonmetallic materials form, and are fabricated structures;Describedly heating wire 3 and magnesium oxide powder 4 are housed in it, draw for single-ended, eduction rod 1 at one end; Described goldBelong to outer heater and the sunk type injection moulding connecting piece 7 that has non-metallic pipe of pipe, adopt nonmetallic materials Shooting Technique systemDo, be shaped with the hole that tubular heater is installed on it, connecting piece mounting center line certain distance should be departed from this hole, reallyProtect in the time that reality is used, electrothermal tube sinks in water tank; In the endoporus of injection moulding connecting piece 7, being shaped with step 8 blocksBlind hole non-metallic pipe 9, and absorb the axial thrust that this pipe produces, straight shape non-metallic pipe 9 and sunk type injection mouldingBetween connecting piece 7, there is seal 2; Retaining ring 10 or make connecting piece 7 and non-metallic pipe 9 by waterproof high-temp glueShould produce contact, guarantee sealing and prevent from non-metallic pipe 9 from from the hole of connecting piece 7, exiting.
Metal tube has the manufacturer of heater and the sunk type injection moulding connecting piece combined electrical heat pipe of non-metallic pipe outwardMethod is in metal tube, to pack heating wire 3 into, with magnesium oxide powder 4, makes heating wire and metal tube insulation, and makesTwo eduction rods 1 are in same one end, become metal tube and be set with the heater 5 of non-metallic pipe outward; In addition by connecting piece7 adopt the manufacture of nonmetallic materials Shooting Technique, after forming two independent components, when assembling, blind hole is nonmetalPipe 9, inserts in the hole of connecting piece 7, and between the two, packs seal 2 into.
The invention has the beneficial effects as follows at tubular metal heater, blind hole non-metallic pipe of outer suit is immersed in waterIn scaling not, can not corrode and puncture, can not leak electricity.
Brief description of the drawings
Fig. 1 is that metal tube has the heater of non-metallic pipe and the combination of the connecting piece of sunk type plastic material injection moulding outwardFormula electrothermal tube structure figure;
Detailed description of the invention
In accompanying drawing, in eduction rod 1, seal 2, heating wire 3, magnesium oxide powder 4, straight shape metal tube, be equipped withHeating wire is also nonmetal with heater 5, nonmetal plug 6, the sunk type of magnesium oxide powder and metal tube insulationThe step 8, the blind hole that in the hole of tubular heater, absorb axial force are installed on material injection moulding connecting piece 7, connecting pieceStraight shape non-metallic pipe or title shell 9, retaining ring 10.
Fig. 1 is that metal tube has the heater of non-metallic pipe and the connecting piece 7 that plastic material Shooting Technique is made outward,Combined structure chart, the function of connecting piece is to be connected with various hot-water heating systems, and makes electrothermal tube at waterIn case, sink, in its endoporus, be shaped with step 8 for blocking the axial force of tubular heater; Tubular metal heater5, be at the in-built heating wire 3 of metal tube, and have magnesium oxide powder 4 and metal tube insulation, lead-out wire is at one end;And at a straight shape non-metallic pipe 9 of blind hole of the outside of tubular metal heater 5 suit.
Described sunk type refers to by Fig. 1 mode and installs, in some product will on lift up so that Fast Heating topWater, can conveniently apply.
