The specific embodiment
Referring to Fig. 1 to Fig. 5; A kind of embodiment that is used for the damping isolator of electric heater that provides at the utility model; Comprise hold-down nut 1, fixed axis 2 and isolated pipe 3; Said fixed axis 2 is sleeved on the said isolated pipe 3, and said hold-down nut 1 is arranged on the said fixed axis 2, the water resistance decay channel isolation that said isolated pipe 3 is processed by insulating materials.When water heater generation electric leakage obtained water heater earthed system existence electric leakage, the water of outflow was through the water resistance series connection dividing potential drop effect of overdamp isolator, and reduction leakage current intensity avoids causing human casualty accident.The utility model simple in structure installs and changes more convenient, and cost is low.
The utility model is processed a device with hold-down nut 1, fixed axis 2 and isolated pipe 3, and said fixed axis 2 is as inserts.Isolated pipe 3 one ends of the utility model are connected with the intake-outlet that water heater connects, and an other end links to each other with the water pipeline.The current of extraneous current and water heater inside are through isolated pipe 3 conductings of damping isolator; Insulated channel 3 is with water heater water inlet pipe and water outlet pipe and the insulation of water pipeline; Avoid the leakage current of water heater to continue to use the direct conducting of waterpipe, cause leakage current to act directly on end user's the human body electric shock accidents takes place.
Referring to Fig. 1 to Fig. 5, in the foregoing description that the utility model provides, the inside diameter D of said isolated pipe 3 and length L are:
| Internal diameter | Length |
| 5mm | ?40mm-173mm |
| 6mm | ?57mm-249mm |
| 7mm | ?77mm-338mm |
| 8mm | 101mm-442mm |
| 9mm | 128mm-560mm |
Consider influence and the product cost of water resistance to water outlet, the optimal selection scope exists:
| Inside diameter D | Length L |
| 5mm | ? 40mm-60mm |
| 6mm | ? 60mm-80mm |
| 7mm | ? 80mm-110mm |
| 8mm | 110mm-140mm |
| 9mm | 140mm-170mm |
In above-mentioned corresponding relation, when the internal diameter of isolated pipe 3 was 5mm, length was preferably 50mm; When the internal diameter of isolated pipe 3 was 6mm, length was preferably 72mm; When the internal diameter of isolated pipe 3 was 7mm, length was preferably 98mm; When the internal diameter of isolated pipe 3 was 8mm, length was preferably 128mm; When the internal diameter of isolated pipe 3 was 9mm, length was preferably 162mm.Above-mentioned corresponding relation can guarantee that leakage current should be less than 10mA under the 220V voltage.Thereby protection user's safety.
Referring to Fig. 1 to Fig. 5, in the foregoing description that the utility model provides, the part of said fixed axis 2 is nested in the said isolated pipe 3, and part dew is put outside and is wrapped on the said isolated pipe 3.Said isolated pipe 3 preferably PPO material or Reinforced Nylon material is processed, and satisfies requirement of strength.Most of isolated pipe 3 in the utility model stretches in the electric heater, puts length outside thereby can effectively shorten to reveal.
Referring to Fig. 1 to Fig. 5, in the foregoing description that the utility model provides, said fixed axis 2 reveals to be put outside end formed snap ring 21 is arranged, and said hold-down nut 1 is sleeved on the said fixed axis 2, and spacing by said snap ring 21.Said hold-down nut 1 enclose said fixed axis 2 the axle coaxial line rotate freely, be strained and fixed the axle 2 and the water heater water inlet between distance, thereby play fixing effect.
Referring to Fig. 1 to Fig. 5, in the foregoing description that the utility model provides, said fixed axis 2 is arranged on the part of said isolated pipe 3 and is formed with annular groove 22.Said annular groove 22 improves the bond strength of fixed axis 2 and isolated pipe 3, thereby improves sealing, prevents leakage.
