Abstract
The utility model discloses an anti-siphon device which comprises a valve body of an automatic water intake valve, wherein an upper valve body and a lower valve body are installed in the valve body, a water-stopping rubber pad is arranged between the upper valve body and the lower valve body, and a main water flow passage is formed between the lower valve body and the water-stopping rubber pad; a valve seat surrounding a water intake pipe extends to the bottom of a water storing tank, an opening of the valve seat is close to the bottom of the water storing tank, a water outlet passage is formed between the inner wall of the valve seat and the outer wall of the water intake pipe, and the side wall of the valve body positioned in the water outlet passage is provided with an outer ventilating hole which is positioned above the prescribed water storing level. The lower side of the lower valve body in the water outlet passage is provided with a water-blocking rubber pad which prevents a water flow from being jetted from the outer ventilating hole. The automatic water intake valve manufactured by the utility model has the advantages of high water intake speed and quiet water intake; when water of a tap water pipe network stops, the water in the water storing tank can not reflow to the tap water pipe network due to the phenomenon of siphon so that a water resource can not be polluted.
Description
Technical field
The utility model relates to the anti-siphon means technical field, relates in particular to a kind of anti-siphon means that is used for the flush toilet automatic water inlet valve.
Background technique
The known automatic water inlet valve that is used for flush toilet, comprise valve body, upper valve body and following valve body are installed in the valve body, are provided with the sealing rubber cushion between the upper and lower valve body, form main flow channel between following valve body and the sealing rubber cushion, main flow channel one end is communicated with intake pipe, its the other end is communicated with water storage box by the exhalant canal of sealing, and the water outlet of exhalant canal is near the bottom of water storage box, like this, when water intake valve, can not send the sound that dabbles.But, because water outlet is not had by the water logging in the water storage box, main flow channel, exhalant canal and water storage box have just formed the sealing connected component, when the tap water pipe network is cut off the water, water in the water storage box can be back in the tap water pipe network by exhalant canal and main flow channel, siphonage promptly takes place, and polluted source.
The model utility content
Technical problem to be solved in the utility model is: a kind of anti-siphon means is provided, and when solution tap water pipe network was cut off the water, the water in the water storage box can be back in the tap water pipe network by main flow channel, causes the problem of pollution of waterhead.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of anti-siphon means, comprise the automatic water inlet valve valve body, upper valve body and following valve body are installed in this valve body, be provided with the sealing rubber cushion between the upper and lower valve body, form main flow channel between following valve body and the sealing rubber cushion, main flow channel one end is communicated with intake pipe, its the other end is communicated with water storage box by the exhalant canal of sealing, the opening of exhalant canal is near the bottom of water storage box, described exhalant canal is provided with outer vent, and this outer vent is positioned at more than the water storage water level of regulation.
As a kind of improvement, seat ring moves into water pipe and extends to the water storage box bottom, and its opening forms described exhalant canal near the water storage box bottom between valve base inner wall and the intake pipe outer wall.
Improve as another kind, in described exhalant canal, the valve body downside is provided with and prevents the dash rubber cushion of current from the outer vent ejection down.
Owing to adopted technique scheme, exhalant canal is provided with outer vent, and this outer vent is positioned at more than the water storage box predetermined water level, so exhalant canal communicates constantly with atmosphere.When the tap water pipe network is cut off the water, water in the outlet pipe refluxes owing to action of gravity produces, but at this moment because water storage box, exhalant canal and main flow water channel do not form airtight connected component, siphonage can not take place, thereby not refluxing in the assurance water storage box can not pollute the water source.Exhalant canal is interior, the valve body downside is provided with and prevents the dash rubber cushion of current from the outer vent ejection down, can prevent effectively that current from sending water from the outer vent ejection and spattering sound, and water inlet is quick and quiet.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a structure sectional view.
Embodiment
As shown in drawings, a kind of anti-siphon means, comprise automatic water inlet valve valve body 1, upper valve body 5 and following valve body 2 are installed in this valve body 1, are provided with sealing rubber cushion 3 between the upper and lower valve body 5,2, form main flow channel A between following valve body 2 and the sealing rubber cushion 3, following valve body 2 is made as one with intake pipe 9, valve seat 1 extends to the water storage box bottom around intake pipe 9, and its opening forms water channel near the water storage box bottom between valve base inner wall and the intake pipe outer wall.The body wall that is positioned at exhalant canal is provided with outer vent 25, and this outer vent 25 is positioned at more than the water storage water level of regulation.In the exhalant canal, following valve body 2 downsides are provided with successively and prevent the dash rubber cushion 16 and the branch fluid 24 that be sheathed on intake pipe 9 of current from outer vent 25 ejections, divide fluid 24 the big branch of water can be introduced water storage box 23, fraction imports water storage box spill pipe (not shown), this minute, fluid 24 1 ends were provided with the supporting lip 17 that leans dash rubber cushion 16, its the other end is provided with axial splitter box 22, supporting lip 17 is provided with interior vent 18, shunt external side face be provided with can with first flange 19 and second flange 21 of valve base inner wall Spielpassung, first, second flange 19, shunting body sidewall between 21 is provided with radially tap hole 26, be provided with the body wall of corresponding position, tap hole 26 position radially and distribute the mouth of a river 20, distribute the mouth of a river 20 and be provided with the water-adding pipe 22 that can be communicated with the water storage box spill pipe.
Because the body wall that is positioned at exhalant canal is provided with outer vent 25, and this outer vent 25 is positioned at more than the water storage water level of regulation, so exhalant canal communicates constantly with atmosphere.When the tap water pipe network is cut off the water, water in the outlet pipe 9 refluxes owing to action of gravity produces, but at this moment because water storage box, exhalant canal and main flow water channel A do not form airtight connected component, siphonage can not take place, thereby guarantee that the water in the water storage box 23 does not reflux, and does not pollute the water source.Dash rubber cushion 16 is set, can prevents effectively that into the water current send water from outer vent 25 ejections and spatter sound, water inlet fast and quiet.Divide fluid 24 to be provided with at siphon wc pan.After the flush toilet draining, the siphon wc pan domestic demand retains a part of water, prevents to return flavor.During the big water quantity draining, produce negative pressure in drain opening, the water capacity in the water closet needs manually to mend a part of water easily by emptying in water closet, seal the return trap of water closet.Dividing the effect of fluid 24 is when water intake valve, by its 26 fens a part of current of tap hole radially, enters water closet from water-adding pipe 22 through the spill pipe of flush toilet, realizes automatic water supplement.
