Description

Flanged or non-flanged non-metal shell electrothermal tube

Technical field

The present invention relates to electrothermal tube, electric heater, central heater, solar water heater, center are related generally to The hot-water heating systems such as air conditioner auxiliary heater, electric hot water, water dispenser, boiler, small kitchen treasured, are immersed in Non-metal shell electrothermal tube in water.

Background technology

Patent application《Non-metal shell heating》Application number 201520816869.3 and 201510688413.8 Describe two kinds of non-metal shell heatings of through type and blind hole；Practice, it is found that there is following defect：1. it is blind Hole pipe has axial force under hydraulic pressure effect, can be by electrothermal tube toward extrapolation；2. main heating part cannot be below installing Center line sinks, and reduces hot water capacity；3. modular construction and mounting means are not illustrated；Present patent application Drawbacks described above will be overcome.

The content of the invention

The purpose of the present invention is right《Non-metal shell heating》Application number 201510688413.8 is mended Fill and improve, new technical scheme is proposed, to overcome the defect of existing product.

Technical measures of the invention are：

The component 8 for having heating wire in blind hole non-metallic pipe and flanged (FLGD) mounting seat 11 are combined into flanged Non-metal shell electrothermal tube 5-1 or be combined into non-flanged non-metal shell with non-flanged mounting seat 12 Electrothermal tube 5-2.

Flanged (FLGD) non-metal shell electrothermal tube 5-1 is that blind hole non-metallic pipe is made into Curved or straight, In-built electrical heated filament 3, the eduction rod 1 of heating wire one end bends to U-shaped in pipe, makes two to draw ear of maize and exists Open wide one end, and by the protruded tube of nonmetallic plug 6 outside, pipe in also have magnesium oxide powder or air 4, draw Line non-metallic insulation spacer 10 is isolated, and prevents short circuit；Non- gold pipe is opened wide into one end and inserts flanged (FLGD) peace In dress seat 11 hole, there is seal 2 between the endoporus and non-metallic pipe of mounting seat, as supporting, seal and subtract Shake；There are screw thread or bayonet socket in mounting seat, be matched therewith with nut or end cap 13, the work(of nut or end cap 13 Can block the mouth of pipe of non-metallic pipe 9, if non-metallic pipe is Curved, blind hole one end is pacified in flange during installation Under dress center line, more hot water can be produced.

Flanged (FLGD) mounting seat 11 metal or nonmetallic materials integral manufacturing or split production, use with water tank 14 Be mechanically connected, the non-flanged non-metal electric heating pipe 5-2, is non-flanged mounting seat 12, directly with Tank weld or mechanical connection, and by electrothermal tube insertion mounting seat hole in, the endoporus and non-metallic pipe of mounting seat Between have seal 2, as supporting, sealing and damping；There are screw thread or bayonet socket in mounting seat, with nut or end Lid 13 is combined with it, and the function of nut or end cap 13 is to block the mouth of pipe of non-metallic pipe.

The beneficial effects of the invention are as follows non-metal shell electrothermal tube, with flanged or non-flanged mounting seat and water tank Connection, makes the axial thrust that Curved or straight blind hole pipe are overcome in water tank, and available flanged or without flange Electrothermal tube, the existing metal electric heating pipe of direct substitution makes existing product not scaling, and leakproof solves binomial World-famous puzzle.

Brief description of the drawings

Fig. 1 is flanged (FLGD) non-metal shell electrothermal tube；

Fig. 2 is non-flanged non-metal shell electrothermal tube；

Fig. 3 is that 2 electrothermal tube schematic diagrames are filled on same flange；

Specific embodiment

In accompanying drawing, eduction rod 1, sealing ring 2, heating wire 3, magnesia powder or air 4, flanged (FLGD) non-gold Category shell electrothermal tube 5-1, non-flanged non-metal shell electrothermal tube 5-2, nonmetallic plug 6, straight-through non-gold Having in category pipe has the component (or electric heating pipe component) of heating wire in the component 7 of heating wire, blind hole non-metallic pipe 8th, blind hole non-metallic pipe 9, non-metallic insulation spacer 10, flanged (FLGD) mounting seat 11, non-flanged installation Seat 12, nut or end cap 13, water tank 14 (not shown in accompanying drawing), flange 15；

Fig. 1 is flanged (FLGD) non-metal shell electrothermal tube 5-1, by the group for having heating wire 3 in blind hole non-metallic pipe Part 8 is constituted with flanged (FLGD) mounting seat 11, and one end of heating wire bends to U-shaped in pipe, makes two extractions Rod is stretched to outside pipe in unlimited one end, and one of lead-out wire non-metallic insulation spacer 10 is entangled；This electricity The electrothermal tube that heat pipe generates heat with the existing metal tube for generally using, mounting means, size for connection is identical, Ke Yizhi The existing electrothermal tube of replacement is connect, the new construction of present patent application, advantage is fairly obvious, because shell is non-metallic material Material make, would not scaling, will not puncture, realize water proof heat, if non-metallic pipe is fabricated to Curved, Blind hole one end can be less than installation center line and sink, therefore during preheating, the hot water of generation can be more；At some In structure, Fig. 2 is that blind hole non-metallic pipe is made into straight to be used in vertical or horizontal double water tank.

Fig. 3 is that 2 electrothermal tubes are filled on same flange, and function phase is same.

Fig. 4 is flanged (FLGD) mounting seat, with metal or nonmetallic materials integral manufacturing, it is also possible to split production, Just turn into the non-metal shell electrothermal tube that can be commonly used after being combined with non-metallic pipe 8.
