Described seal arrangement comprises seal washer and pressing plate, and seal washer is positioned at the below, and both ends of the spring withstands between pressing plate and the position shelf.
Described Returnning spring two ends hold out against respectively between pressing plate and positioning plate.
The utility model structural design advantages of simple, inner liner pressure can in row also can efflux, improved the Safety performance of electric water heater, the place that it also keep to be installed can be moist always, improved the health in bathroom and dry and comfortable.
Description of drawings
Structural representation when Fig. 1 is intake for embodiment;
Structural representation when Fig. 2 is inside pressure release;
Structural representation when Fig. 3 is outside pressure release.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In conjunction with Fig. 1 to Fig. 3, the reduction valve that a kind of electric water heater is used, comprise valve body 1, be provided with intake tunnel 2 and pressure release passage 3 in valve body 1 body, be communicated with by on valve body wall, offering through hole 4 between pressure release passage 3 and the intake tunnel 2, be provided with the sealing plate 5 of shutoff through hole in pressure release passage 3, sealing plate 5 is realized the shutoff through hole by elastic component 6 extruding, and the valve body wall of corresponding pressure release passage is provided with and is communicated with pressure release passage 3 and extraneous relief hole 7.Intake tunnel lower end mouth 20 is connected with the tap water pipe network, and intake tunnel upper end-hole 21 is connected with inner container of electric water heater.
The valve body of described intake tunnel 2 bottoms inwardly shrinks and forms a circle step 8, step 8 central authorities are provided with the water intake 9 of a up/down perforation, water intake 9 positions are lower than through hole 4 positions, the upper body of intake tunnel is provided with a circle internal thread 10, have a position shelf 11 to be threaded with valve body 1, position shelf 11 is the netted current that make to be passed through in its body.Position shelf 11 central positions are equipped with a screw rod 12, wherein the nut 13 of screw rod is positioned at the position shelf below, nut 13 diameters are less than water intake 9 diameters, the screw rod of nut 13 tops is coated with seal washer 14 successively, pressing plate 15 and positioning plate 16, seal washer 14 is positioned at the below, screw rod is seal washer 14 relatively, pressing plate 15 and position shelf 11 move up and down, but positioning plate 16 is fixedlyed connected with screw rod, be provided with tower shape spring 17 between pressing plate 15 and the position shelf 11, spring 17 upper end end areas are long-pending greater than lower end surface, seal washer 14 is sealed into the mouth of a river 9 by spring 17 elastic force, be provided with Returnning spring 18 between pressing plate 15 and the positioning plate 16, Returnning spring 18 is positioned at spring 17 inner rings, and Returnning spring 18 two ends are top pressing board 15 and positioning plate 16 respectively, and the elastic force of Returnning spring 18 is less than the elastic force of elastic component in the pressure release passage 6.
The working principle of said structure is: the intake pressure of tap water under normal circumstances is greater than the elastic force of spring 17, and therefore, spring 17 is pressed to shrink, and seal washer and pressing plate rise away from water intake, and tap water enters the inner bag heating by water intake 9.When inner liner pressure excessive, seal washer is pressed in the ledge surface of water intake periphery, inner liner pressure pushes away positioning plate downwards, screw rod moves downward, make between seal washer inner ring peripheral distortion and the screw rod outer surface and produce the gap, the steam of inner bag enters the tap water pipe network by the gap from intake tunnel downwards, drains in this pressure release is referred to as and presses.When tap water pressure is big especially, and always greater than inner liner pressure, this moment, water intake was in into water state always, steam in the inner bag can't the row of descending, at this moment the elastic component 6 in the pressure release passage is compressed, and the steam of inner bag is drained from pressure release passage, and this drainage is referred to as to efflux.Reduction valve of the present utility model has interior row and effluxes two kinds of functions of pressure, takes place when tap water pipe network pressure is big especially but only efflux, and all drainage pressure in the tap water pipe network under the normal condition, the bathroom can keep dry like this.
