Abstract
The utility model discloses a water inlet valve against siphon. A head cover is arranged on the valve body, and a first cavity is formed between the head cover and the valve body. A guide location bracket fixed in the first cavity is arranged in the head cover, and a tubular floater is arranged in the guide location bracket whose upper end is larger than the open position of the head cover. A second cavity formed between a shaft and the valve body is communicated with the first cavity through transfixion mouth arranged on the valve body, and the first cavity is communicated with a water outlet pipe through an outlet arranged on the valve body. A water inlet, the first cavity, and the second cavity are in negative pressure when siphon phenomenon takes place at the water inlet, then the floater detaches from the transfixion mouth of the head cover under the compression of the external atmospheric pressure and goes to the first and the second cavity through an air inlet of the head cover with a result of destructing siphon, which prevents the water of the water tank from backward flowing in to the water inlet, thereby the water source is avoided from polluting by the water of the tank. The utility model is in accordance with the national and international standards because of the improvement of the structure and performance.
Description
Technical field
The utility model relates to a kind of toilet seat water tank accessory, specifically relate to a kind of structure improvement anti-hydrocone type inlet valve.
Background technique
In the prior art, the inlet valve of toilet seat water tank is through updating, and structure is gradually improved, and performance is improved constantly.But in being to use, often because factors such as tap water hydraulic instabilities, cause inlet valve to produce siphonage, water in the water storage box into intake pipe that can flow backwards, pollute the water source, this at home be that strictness is forbidden on the international standard, therefore need do further to improve to the structure of inlet valve, to avoid siphonage.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of anti-hydrocone type inlet valve is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of anti-hydrocone type inlet valve, bottom at the valve casing intake pipe is provided with ceramic moving plate and the ceramic still that cooperatively interacts, the pottery moving plate connects an axostylus axostyle, axostylus axostyle is stirred and is rotated by being set in floating drum on the intake pipe, a top cover is set above the described valve casing, constitutes first cavity between top cover and the valve casing; A guide-localization frame is set in top cover, and the guide-localization frame is fixed in first cavity; In the guide-localization frame float is set, float is tubular, adopts lightweight material to make, and bulk strength is better, and can also can up float smoothly when hydraulic pressure is very low, and its upper-end surface is uncovered greater than top cover; Second cavity that constitutes between described axostylus axostyle and the valve casing is conducted by the openings and first cavity that is arranged on the valve casing; Described first cavity is conducted by water outlet and the outlet pipe that is arranged on the valve casing.
As the further improvement of technological scheme, the side near water outlet on the described valve casing is provided with water supplement port, and water supplement port and water storage box are conducted; The upper-end surface of described float is provided with rubber sheet gasket, when float floats, and can be with the uncovered sealing of top cover; The valve casing side of described axle end is provided with a gag, is used to limit the degrees of freedom of axostylus axostyle, makes it to rotate in several angle, opens or closes inlet valve.
The utility model is to set up an anti-siphon mechanism on the structure of original inlet valve, when producing siphonage on the intake pipe, intake pipe, first cavity and second cavity all are in negative pressure, thereby external atmosphere pressure can be oppressed float and become nature to break away from the uncovered of top cover this moment, ambient air enters first cavity and second cavity by the suction port of top cover, destroy siphon, stop the aqueous reflux in the water storage box to advance intake pipe, avoided the water of water storage box to pollute the water source.
The utility model is simple in structure, designs ingeniously, rationally distributed, makes improvements slightly on original inlet valve structure, and overall performance is again improving, and cost increases seldom, meets the requirement of domestic or international standard, helps applying of its market.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2, the utility model is that a top cover 2 is set on valve casing 1, top cover 2 by its uncovered 22 and suction port 14 and extraneous conducting, guide-localization frame 5 of first cavity, 15 internal fixation between top cover 2 and valve casing 1, tubular float 4 is set in the guide-localization frame 5, float 4 upper ends are provided with rubber sheet gasket 3, utilize rubber sheet gasket 3 to stop ambient atmos to enter in first cavity 15 during float 4 come-ups less than top cover 2 uncovered 22 sealings of float 4 upper-end surfaces by suction port 14.In valve casing 1 intake pipe bottom ceramic moving plate 9 and the ceramic still 8 that cooperatively interacts is set, ceramic moving plate 9 wherein connects an axostylus axostyle 7, and valve casing 1 side of axostylus axostyle 7 ends is provided with a gag 6, is used to limit the degrees of freedom of axostylus axostyle 7, make it in several angle, to rotate, open or close inlet valve.Valve casing 1 side relative with axostylus axostyle 7 ends is provided with hinge bar 11, the hinged in the lump rocking arm 10 in hinge bar 11 and axostylus axostyle 7 ends, and the base portion of rocking arm 10 is connected with pole 12, and the base portion of pole 12 is provided with on the floating drum 13, and floating drum 13 is set on the intake pipe 19.Second cavity 17 that constitutes between axostylus axostyle 7 and the valve casing 1 is conducted by the openings 16 and first cavity 15 that is arranged on valve 1 shell; First cavity 15 is conducted with outlet pipe 20 by the water outlet 21 that is arranged on the valve casing 1.Side near water outlet 21 on the valve casing 1 is provided with water supplement port 18, and water supplement port 18 is conducted with water storage box.
The utility model working procedure is such: after the water storage box draining, floating drum 13 is because the deadweight whereabouts, interlock rocking arm 10 rotation; rocking arm 10 drives axostylus axostyle 7 rotations again and makes ceramic relatively still 8 rotations of ceramic moving plate 9; open inlet valve; first cavity 15, second cavity 17, water supplement port 18 and water outlet 21 connect all the time in the water inlet process; can form hydraulic pressure first cavity 15 in; and float 4 is up moved and to utilize rubber sheet gasket to seal up top cover uncovered; this moment, the water of first cavity 15 just can not outflow from suction port 14, can only be from water outlet and water supplement port outflow.After water inlet finished, floating drum 13 was closed inlet valve, stops into water.In the water inlet process, because when factors such as hydraulic pressure instability cause intake pipe to produce siphonage, intake pipe 19, first cavity 15 and second cavity 17 all are in negative pressure, this moment, thereby external atmosphere pressure can be oppressed uncovered 22 of 4 one-tenth natures disengagings of float top cover 2, ambient air enters first cavity 15 and second cavity 17 by the suction port 14 of top cover 2, destroy siphon, stop the aqueous reflux in the water storage box to advance intake pipe, avoided the water of water storage box to pollute the water source.The utility model is to do suitably to improve in structure, and performance improves the requirement that is met domestic or international standard.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
