Embodiment
The outer side wall of electric hot water tap container 6 lower ends is provided with the electric hot water tap screw thread, is provided with the container end cavity 11 of no ceiling in the container end 1, on the madial wall of container end cavity 11, establishes the container end screw thread that matches with the electric hot water tap screw thread; Be provided with columniform projection piece 12 at container end cavity 11 bottom surfaces; In projection piece 12, be provided with the projection piece cavity 13 of up/down perforation; Projection piece cavity 13 madial walls are provided with gutter 15 (gutter 15 from the tops of projection piece cavity 13 madial walls until projection piece cavity 13 madial walls bottom), are provided with pressure relief opening 14 in the upper end of projection piece cavity 13.
Concrete is that silica gel stopple 2 is inserted from projection piece cavity 13 lower ends, blocks pressure relief opening 14 fully up to plug 21; In plug cavity 23, overlap the holddown spring 3 of packing into; Holddown spring fixed plate 4 is fixed on the lower end of projection piece cavity 13 in the lower end of holddown spring 3; Use glue to be adhesive with PVC trim 5 (PVC trim 5 is only done to decorate and is used in the lower end of holddown spring fixed plate 4; Under the pressure of water, promptly can drop).
The bottom of pressure chamber 60 is provided with switch cavity plug 65; Switch cavity plug 65 is used to reduce the volume of water in the pressure chamber 60, with prevent water when freezing volumetric expansion and cause energized (because water is when freezing, volume can expand about 10%; And the amount of the water in the minimizing pressure chamber 60; Can reduce total volume that water increases when freezing, to reach water when freezing, total volume is not enough to the purpose of jack-up glued membrane 63 in the pressure chamber 60).
The utility model the electric hot water tap real work of antifreeze pressure relief device is housed the time, main antifreeze blowdown step is (the water heating process of electric hot water tap that antifreeze pressure relief device is housed is identical with existing electric hot water tap) as follows:
The electric hot water tap that antifreeze pressure relief device is housed under freezing state and non-normal working (be that water outlet stops up and water freezing in the container; Volumetric expansion 10% during water freezing; And the water of 60 li of pressure chambers that hydraulic pressure starts when expanding volume increase can be glued membrane 63 jack-up and energized, and the water freezing in the heating chamber, heating pipe heating; Ice can be vaporized; And the thermal fuse-link of this machine configuration itself is because freezing reason has little time action, and electric heating tube heats and will burn machine like this) time, the electric hot water tap of the antifreeze pressure relief device of the utility model have following several aspects effect:
1, when the pressure of 62 li of heating chambers surpasses 1.1Mpa; The hydraulic pressure that heating chamber is 62 li will back down silica gel stopple 2, and holddown spring 3 begins to shrink, and plug 21 no longer withstands pressure relief opening 14; The water of this moment can be under the guiding of gutter 15; Arrive holddown spring fixed plate 4, flow out (at this moment, PVC trim 5 just drops after receiving the pressure of water) by relief hole 41 again.
2, the inside of silica gel stopple 2 is hollow, can't move as freezing the jail when silica gel stopple 2, can compress silica gel stopple 2 when the pressure that heating chamber is 62 li is excessive, and the purpose that the volume of silica gel stopple 2 reduces also can reach pressure release like this is to prevent that container is by bursting by freezing.
3, silica gel stopple 2 seals with the madial wall of pressure chamber 60; Load onto a switch cavity plug 65 that reduces the pressure switch cavity volume; The volumetric expansion of 60 li ice of pressure chamber can not connected circuit and (needed certain pressure in the time of will starting because of glued membrane 63, and reduce the volume of water, when water freezes in the time of guaranteeing water freezing; Do not reach the pressure of machine startup because water is few, just can not be glued membrane 63 jack-up and energized).
Have the electric hot water tap of the antifreeze pressure relief device of double insurance through this device, when guaranteeing that pressure surpasses 1.1Mpa, can releasing pressure automatically and keep the electric hot water tap no electric circuit of antifreeze pressure relief device.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
