Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, Fig. 4 is the sectional view of baffle in the utility model, as shown in the figure, a kind of cistern for toilet becomes water level non-submersion water intaking valve, comprise housing 1, floating drum 2, connecting rod 3, floating drum lead ring 4, water pocket hole gland 5, water pocket plastics upper body 6, water pocket body 7, baffle 8, water inlet pipe 9, water inlet base 10, floating drum 2 connects water pocket hole gland 5 by connecting rod 3, for controlling lifting or putting down of water pocket hole gland, and then opens or close water pocket body.Floating drum 2 bottom connects floating drum lead ring 4, and floating drum lead ring 4 can move up and down outside housing 1, thus affect moving up and down of floating drum.Water pocket hole gland 5 is pressed on the aperture on water pocket body 7, and water pocket plastics upper body 6 is between water pocket hole gland 5 and water pocket body 7 and be connected with between housing 1, and water pocket body is pushed down in the effect of water pocket plastics upper body, prevents it from floating.Be baffle 8 bottom water pocket body 7, water inlet pipe 9 passes from baffle 8 center, and water inlet pipe 9 open top, by water pocket body 7 shutoff, is sleeved on in water base 10 bottom water inlet pipe 9, affixed with water inlet base 10 bottom housing 1.In prior art, be have the mouth of a river in baffle side, through improvement of the present utility model, longitudinally have water channel 11 in described baffle 8, the side of housing 1 has multiple delivery port 12 from top to bottom.That is, current flow down through baffle, flow out from housing side delivery port.
Discharge water in the work period a water inlet, water level in water tank changes from low to high, the water body flow to downwards in annular water outlet sleeve through baffle selects one or several delivery port to flow in water tank naturally nearby, material is thus formed the ideal effect of non-submersion orifice outflow.Because when in water tank, water level raises gradually, by the no longer water outlet of the delivery port of water flooding, this just ensure that the position of water body forever in water tank more than water level in annular water outlet sleeve enters water tank by delivery port from start to finish, in other words, water level in case raises gradually, and is also save land raise along with water level one saves one from the water body that vertical delivery port flows out.The baffle internal gutter structure determined according to hydraulic principle, the area of delivery port; fully can ensure that the instantaneous water level in water tank and in annular channel is a horizontal plane completely; this horizontal plane is forever lower than water inlet horizontal plane; and this horizontal plane communicates with air all the time; therefore fully and completely siphon can be stopped; prevent the water in cistern for toilet from flowing backwards, protection water body is not contaminated.
Water channel 11 diameter in described baffle 8 is up big and down small, by reducing the cross-sectional area of water channel, can accelerate current, sweeping away under making current direction.Concrete, described water channel 11 is four.
