" regulation about sanitary appliance " delivery port must not by any liquid or impurity flood ".In addition, because the valve gap of water intaking valve controls by water level buoy lifting in case, if when water supply line is cut off the water suddenly in the midway of water tank water intake and produces negative pressure (this is recurrent thing), valve gap is in opening, water level in case is again higher than delivery port, water in case is just blowed back into due to siphonage in water supply line by the delivery port opened, and the water of pipeline is contaminated.At present, often have both at home and abroad and flow into coloured thimerosal the report that drinking water pipeline flows out from water tap about in toilet seat.
2, " surface type water intaking valve " (Fig. 2) designs in order to avoid the siphonage of " burying ability of swimming " water intaking valve, its rely on the water flowing micropore of switch rubber " water pocket " realize water tank enter to cut off the water." water pocket " main body is by having good elastic caoutchouc manufacture, and in case, water is difficult to " siphon refluence ", and for this reason, some producers also claim this valve for " anti-hydrocone type water intaking valve ".But once inlet channel produces larger negative pressure value, or water pocket quality of rubber materials is aging, siphon refluence can be produced too and pollute tap water phenomenon.In addition, this valve has upper and lower two groups of water inlets.Lower water inlet bears most of inflow.The upper end of water intaking valve shell is generally provided with a mouth of a river, claims in " moisturizing hole ", extends to moisturizing at the bottom of case with sebific duct.The delivery port of " anti-hydrocone type water intaking valve " is all submerged in waterbox design underwater, does not meet the regulation of " (GB50015-2009) be 2. 4A 3. ".
Based on this kind of phenomenon, have people one way stop peturn valve to be installed on water tank to prevent the generation of siphonage, but the limited use of one way stop peturn valve, and the generation that can not prevent siphonage thoroughly, because the flap sealing in valve body is not thorough.
Therefore, need to design a kind of water intaking valve and thoroughly can stop the problem that cistern for toilet siphon causes water pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of cistern for toilet without flooding without siphon inlet valve, solves the problem that existing cistern for toilet water intaking valve easily causes siphonage, thus eliminates the phenomenon of water pollution.
The utility model is achieved through the following technical solutions: cistern for toilet is without flooding without siphon inlet valve, comprise housing, floating drum, connecting rod, floating drum lead ring, water pocket hole gland, water pocket plastics upper body, water pocket body, baffle, water inlet fall way, water inlet pipe, floating drum connects water pocket hole gland by connecting rod, floating drum bottom connects floating drum lead ring, floating drum lead ring can move up and down along hull outside, water pocket hole gland is pressed on the aperture on water pocket body, water pocket plastics upper body between water pocket hole gland and water pocket body and and affixed between housing, it is baffle bottom water pocket body, baffle side has the mouth of a river, water inlet fall way passes from baffle center, be sleeved in water inlet pipe bottom water inlet fall way, described water inlet pipe top and baffle connect as one, and are communicated with the mouth of a river on baffle.
Further, the described mouth of a river is multiple.
Further, open-topped tubule is connected with above described each mouth of a river.
Adopt the good effect of technique scheme: the delivery port of the utility model valve body is positioned at waterbox design water surface top, to meet in " Code for design of building water supply and sewerage " (GB50015-2009) regulation of " delivery port must not by any liquid or impurity flood ", cut off the water and produce negative pressure can not blow back into polluted drinking water in water supply line due to siphonage by the water in absolute guarantee's cistern for toilet once water supply line; Meanwhile, have siphon destructive mouth, thoroughly stop siphon, prevent the water in cistern for toilet from flowing backwards, protect other water bodys not contaminated.
