The specific embodiment
Extremely shown in Figure 5 as Fig. 2, in electrical equipment body 12, be provided with many water-flowing troughs 14 in the present embodiment---about each 13, water-flowing trough vertically is provided with being up/down perforation every electrical equipment body inside, circular array is at (Fig. 2 in the electrical equipment body then, dash area among Fig. 3 is expressed as " low 5mm " herein), every electrical equipment body 12 top and bottom respectively with two upper end covers 10, two bottom end covers 7 link to each other, as shown in Figure 1, every the electrical equipment body and be lined with the last sealing ring made from elastomeric material 9 up and down between the end cap, lower seal 8, making the junction sealing water-tight, is respectively bottom end cover as Fig. 6 to Fig. 9, upper end cover, the bottom end cover sealing ring, the schematic diagram of upper end cover sealing ring.Screw rod 11, nut 5 and packing ring 6 up and down end cap, link together every electrical equipment body, upper-lower seal circle.All adopting every electrical equipment body 12 and upper end cover 10, bottom end cover 7 in the present embodiment is that high pressure resistant and PE material high-insulation of high temperature is made, and these the three kinds of parts in the utility model also can adopt other the high-temperature-resistant high-pressure-resistant and the material of high-insulation to make certainly.
After electrical equipment body 12 and upper end cover 10 and bottom end cover 7 connected, 13 of every side water-flowing troughs had just constituted the long water flowing passage of a single sealing in electrical equipment body 12.To after cutting open, radius (as the B-B among Fig. 2) be launched into the plane as shown in Figure 5 every electrical equipment body 12 right-hand components.Water inlet 1 every the electrical equipment body only directly communicates with a water-flowing trough, only directly communicate every electrical equipment delivery port 1 equally with a water-flowing trough, other tank has end cap and sealing ring sealing up and down, so, then join end to end in order at 13 water-flowing troughs in the electrical equipment body and to constitute the water flowing passage of a long sealing, after water enters from water inlet 1, enter water heater from delivery port one 2 outflows then through this water flowing passage.Equally, the delivery port of water heater links to each other with water inlet 23 every electrical equipment, and the water in the water heater is from entering every electrical equipment every electrical equipment water inlet 23, through behind another water flowing passage of electrical equipment from flowing out every electrical equipment delivery port 24.
Present embodiment be to merge every electric installation by two cylinder types to form every the electrical equipment body, 13 water-flowing trough cross-sectional areas that each the inside is provided with are all the same, article 13, the water-flowing trough water flowing passage that to connect into a length be 900～1200mm, because of running water conductance lower, resistivity is greater than 1300 Ω cm, so form the above resistance of 1 megaohm behind the running water process water flowing passage.Charged as the water in the water heater; process is behind a water flowing passage of electrical equipment when flowing out; voltage can be attenuated to safe voltage even be 0; to reveal electric current isolates gradually; realized when leaking electricity electricity isolated purpose with the protection personal safety because of water heater liner; as a same reason, in the middle of the water inlet of water heater and the interface channel of municipal tap water with link to each other every another water flowing passage of electrical equipment, played two-way buffer action.
