Description

Non-metal shell electrothermal tube

Technical field

The utility model relates to electrothermal tube, relates generally to electric heater, central heater, solar water heater, central hollow The hot-water heating system such as adjust auxiliary heater, electric hot water, water dispenser, boiler, little kitchen precious, be immersed in water nonmetal outside Shell electrothermal tube.

Background technology

Patent application " non-metal shell heating " application number 201520816869.3 and 201510688413.8 describes Through type and two kinds of non-metal shell heatings of blind hole；Practice, it is found that there is following defect: 1. blind hole pipe is in hydraulic pressure effect Under have axial force, can by electrothermal tube toward extrapolation；2. main heating part cannot be below installing center line and sinks, and makes hot water capacity Reduce；Modular construction and mounting means are not the most described, present patent application will overcome drawbacks described above.

Utility model content

The purpose of this utility model is to supplement " non-metal shell heating " application number 201510688413.8 And improvement, new technical scheme is proposed, to overcome the defect of existing product.

Technical measures of the present utility model:

One is to be combined into flanged (FLGD) by the assembly 8 having heating wire in blind hole non-metallic pipe with flanged (FLGD) mounting seat 11 Non-metal shell electrothermal tube 5-1.

Two is the assembly 8 by there being heating wire in blind hole non-metallic pipe, and being combined into non-flanged mounting seat 12 cannot be blue Non-metal shell electrothermal tube 5-2.

Described flanged (FLGD) non-metal shell electrothermal tube 5-1 is that blind hole non-metallic pipe is made Curved or straight, built-in Heating wire 3, the eduction rod 1 of heating wire one end, in pipe, bend to U-shaped, make two to draw ears of maize in unlimited one end, and by non- Outside metal plug 6 protruded tube, also having magnesium oxide powder or air 4 in pipe, lead-out wire non-metallic insulation spacer 10 is isolated, anti- Only short circuit；Non-gold pipe is opened wide one end insert in flanged (FLGD) mounting seat 11 hole, have between endoporus and the non-metallic pipe of mounting seat Seal 2, is used as supporting, seals and damping；There are screw thread or bayonet socket in mounting seat, are matched therewith with nut or end cap, nut Or the function of end cap is to be blocked by the mouth of pipe of non-metallic pipe 9, if non-metallic pipe is Curved, blind hole one end heart line in an installation it Under, more hot water can be produced.

Flanged (FLGD) mounting seat 11 metal or nonmetallic materials integral manufacturing or split production, with water tank 14 machinery side Formula connects, and described non-flanged non-metal electric heating pipe 5-2, is non-flanged mounting seat 12, directly connects with tank weld or machinery Connect, and electrothermal tube inserted in the hole of mounting seat, between endoporus and the non-metallic pipe of mounting seat, have seal 2, be used as supporting, close Envelope and damping；Having screw thread or bayonet socket in mounting seat, combined with it with nut or end cap, the function of nut or end cap is by non-gold The mouth of pipe belonging to pipe blocks.

The beneficial effects of the utility model are non-metal shell electrothermal tubes, with flanged or non-flanged mounting seat and water tank Connect, make the axial thrust that Curved or straight blind hole pipe overcome in water tank, and available flanged or non-flanged electrothermal tube, Direct substitution existing metal electric heating pipe, makes existing product not scaling, leakproof, solves binomial world-famous puzzle.

Detailed description of the invention

In accompanying drawing, eduction rod 1, seal 2, heating wire 3, magnesia powder or air 4, flanged (FLGD) non-metal shell electric heating Have in pipe 5-1, non-flanged non-metal shell electrothermal tube 5-2, nonmetal plug 6, blind hole non-metallic pipe heating wire assembly 8, Blind hole non-metallic pipe 9, non-metallic insulation spacer 10, flanged (FLGD) mounting seat 11, non-flanged mounting seat 12, nut or end cap 13, water tank 14, flange 15；

Fig. 1 is flanged (FLGD) non-metal shell electrothermal tube 5-1, by the assembly 8 and the band that have heating wire 3 in blind hole non-metallic pipe The mounting seat 11 of flange is constituted, and one end of heating wire bends to U-shaped in pipe, makes two eduction rods stretch to pipe in unlimited one end Outward, one of them lead-out wire non-metallic insulation spacer 10 entangles；This electrothermal tube is sent out with existing commonly used metal tube The electrothermal tube of heat, mounting means, size for connection is identical, can be with the existing electrothermal tube of direct substitution, and the new construction of present patent application is excellent Point fairly obvious, due to shell be nonmetallic materials make, would not scaling, will not puncture, it is achieved water proof heat, if not golden Belonging to control and be made Curved, blind hole one end less than installing center line and can sink, when therefore preheating, and the hot water meeting many of generation A bit；In certain structures, Fig. 2 is blind hole non-metallic pipe to be made straight may be installed use in vertical or horizontal double water tank.

Fig. 3 is to fill 2 electrothermal tubes on same flange, and function is identical.

Fig. 4 is flanged (FLGD) mounting seat, with metal or nonmetallic materials integral manufacturing, it is also possible to split production, with non-gold Just become, after belonging to pipe combination, the non-metal shell electrothermal tube that can commonly use.
