According to the invention, the problems of finely regulating the water storage height by the large drainage fixed floater of the traditional drainage valve according to the size of a water inlet and being incapable of controlling large drainage quantity because too much water is filled in the traditional water tank are overcome so that the water pressure advantage of the height of the water tank is fully developed, therefore, purposes of vigorous washing, clean replacing and water saving are fully realized.

Description

Multistage pressure guide drainage valve

Technical field

The present invention relates to a kind of valve, particularly relate to and a kind ofly for making full use of hydraulic pressure potential energy in cistern, carry out bedpan and scrub and the multistage pressure guide drainage valve of replacing.

Background technology

It is really too important that the mankind economize on water, and according to authoritative department statistics, approximately 1,500,000,000 populations of more than 80 countries in the whole world lack clean drinking water at present, and wherein 29 4.5 hundred million national populations are lived in exsiccosis completely.At present, China's water resource critical shortage, water resource owning amount is only 1/4th of world average level per capita.

How do sanitary equipment economize on water? centuries, people design a lot of ways.About the water consumption requirement of sanitary equipment, there is compulsory standard in many flourishing states.

In fact, the deep connotation of the water saving of sanitary equipment is not a problem that simple water consumption is how many, and should be to replace under double condition completely and the minimizing water consumption of trying one's best guaranteeing that bedpan washes with addle.And people are judging that the good and bad standard element of sanitary equipment is very incomplete, such as washing force problem, just only have a kind of detection Food Red whether residual.And Food Red chance water just flows away, washing force size just cannot be checked.For another example replacement ratio problem, time swap have long have short, vary, do not have good way to go to detect yet.

By China, the water consumption standard of water-saving toilet is 3,6 liters; The water consumption standard of pan is 8 liters.In some big city municipalization sanitary equipment water saving standard access systems of China, implementation status can be quite a lot of.Because water consumption is lessly fixed, a lot of sanitary equipment be not scrub bad be exactly replace not good enough, so, people's sanitary equipment when mounted at once by the float of water intaking valve toward raising, water consumption is strengthened arbitrarily.Reason is following two aspects: one is that the water consumption standard of 3,6 liters is really tighter, and accomplish to wash and replace is very difficult completely; The 2nd, there is the defect of structure aspects in sanitary equipment itself, no matter is low level cistern or high level cistern, and washing force is all very undesirable.

Can why the toilet of high level cistern is scrubbed and replaced in the standard water consumption situation of 3,6 liters be up to standard? reason is that water guide circle and the interior empty volume of aqueduct of toilet (comprising pan) is too large, this sky volume approximately has 2 liters, add nearly 30 on water guide circle and scrub the hole water more than 1 liter that will pour off in the process of filling up, so, no matter water tank has many height, pressure to have much to water more than 3 liters, the potential energy of its water all discharges in this sky volume, only some weight of surplus water is slowly toward dirty, so it is all weak to scrub the water of hole and spray-hole outflow.If use 6 premium on currency, water potential energy more than 3 liters has above consumed, after only have water more than 2 liters, and water level is low, hydraulic pressure has declined again, so effect is always not ideal enough.For this problem, I declared " pressure-guiding bedpan " patent of invention in 2007, had issued the patent certificate of 200710143460X in May, 2009 to me.This patent is exactly that to utilize the pressure of water in the pilot principle of water and dynamic closed container be not have directive principle, and the potential energy that makes full use of water in water tank improves the kinetic energy of scrubbing and replacing.In patent working, effect has clear improvement, but not very good.Reason is that centuries people do not recognize the hydraulic pressure decay that in aqueduct and water guide circle, empty volume causes, and the effect of high level cistern and low level cistern does not have much differences, causes not filling more water in high level cistern yet, would rather allow water tank empty.So, Shui Jian factory does not only utilize the draining valve of high water level to sell yet.There is no this special draining valve, the hydraulic pressure potential energy of high level cistern just cannot use.

Now on market, omnifarious draining valve has, high short, thick thin available in all varieties., the scope of street restaurant's regulating level of these draining valves is all very little, because control the float of street restaurant, is the bottom that is positioned at water key.When the water in water tank is darker, even little gear has been transferred to limit standard, while using street restaurant, because the float position of street restaurant is fixed, can only finely tune to realize valve closing sooner or later by the size of inlet opening, thereby adjustable scope is minimum, the control criterion that water consumption just cannot be realized ideal.So, now no matter large water tank or little water tank, no matter low level cistern or high level cistern of the sanitary equipment on market, the water that the inside fills is all substantially similar, the adjustable extent of water key is also substantially similar.This one of them the most key problem is: people also do not recognize that sanitary equipment will wash, and must make full use of the pressure of existing water level; More do not recognize the corresponding formulation problems of the poor and draining valve of the level pressure how utilizing in water tank.Certainly, do not have pressure-guiding bedpan to come out, just there is no the ample scope for abilities of pilot water key yet.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of can fully be transmitted to the potential energy of water in cistern the washing force that acts on bedpan and the multistage pressure guide drainage valve that improves sewage replacement ratio, thereby fully realization is scrubbed energetically, replaced totally and the object of water saving very.

Above-mentioned technical problem of the present invention is that the draining valve by a kind of following structure is provided solves, this multistage pressure guide drainage valve comprises: key body, arrange key, float key, float float, float slide bar, float positioning tooth, float key card, key main shaft greatly, arrange slide bar greatly, arrange float greatly, arrange the compositions such as key card, large registration tooth, diaphragm seal greatly, the float of the large row of described control and float water supply volume can be on slide bar separately arbitrarily adjustment highly control displacement number.

Multistage pressure guide drainage valve of the present invention tool compared with existing draining valve has the following advantages:

Because the float of controlling large row and float water supply volume can be adjusted arbitrarily height on slide bar separately, overcome the large row's of existing draining valve fixing float and size that can only inlet opening is finely tuned the problem of water height, solved because the in-built water of water tank many and the problem of uncontrollable large row's displacement is brought into play the hydraulic pressure advantage of water tank height fully.Particularly adopt after the pressure-guiding bedpan patented technology of my invention, in bedpan water guide circle, as long as little water just can fill up, thereby just the level pressure in water tank can be transmitted to each, scrub on hole.Experiment shows: in the time of within water consumption is controlled at 4 premium on currency, a medium water tank that 30 centimeters of left and right are high, if adopt pressure-guiding bedpan and the present invention's " multistage pressure guide drainage valve ", it is more than 3 times that the pressure of scrubbing hole current is existing toilet that (the hole pressure of scrubbing of existing toilet only has 0.6 kPa, adopt pressure-guiding bedpan and pressure of the present invention to have 2.3 kPas), replacement result is also significantly increased.

Accompanying drawing explanation

The embodiment of multistage pressure guide drainage valve of the present invention is described below with reference to accompanying drawings.

Fig. 1 is multistage pressure guide drainage valve embodiment structural representation of the present invention.

The specific embodiment

Fig. 1 shows the specific embodiment of multistage pressure guide drainage valve of the present invention.The structure of rough structure and existing sanitary equipment draining valve is similar, just float key 1 and the large row 2 little floats 11 of controlling respectively and arrange greatly float 4 and be the governor motion of two function symmetries.The surface structure of key body 3 is also similar with general water key.When people use large row, because large row's key 2 can be lifted highlyer by key main shaft 8 after depressing, in the situation that large row's float 10 has to buoyancy all the time, through transmission mechanism effect, make large registration tooth 11 be arranged greatly key card 12 and block.Now, from legend, can find out: diaphragm seal 13 is lifted very highly, approach soon the bottom against key body 3; Float float 4 is higher than large row's float 10; Float positioning tooth 6 also has an intersegmental gap from float key card 7.Like this, the water level of water tank just is only subject to arrange greatly float 10 and controls height.And arrange greatly float 10, can on large row's slide bar 9, slide arbitrarily, so the adjustable range of large displacement just can be controlled arbitrarily.

When people use float, because float key 1 can only be lifted key main shaft 8 little by little height after depressing, in the situation that float float 4 has to buoyancy all the time, through transmission mechanism effect, float positioning tooth 6 is blocked by float key card 7.Now, diaphragm seal 13 is just lifted not highly, from the bottom of key body 3, has certain distance; Equally, float float 4 is higher than large row's float 10; Now, large registration tooth 11 also has an intersegmental gap from large row's key card 12, is not also pulled to the height that can tangle.Like this, the water level of water tank is just only subject to float float 4 to control the high end.And float float 4 can slide arbitrarily on float slide bar 5, so the adjustable range of little displacement also just can be controlled arbitrarily.

Similarly structural principle, we can increase multiple controlling organizations and control the displacement in water tank in key body 3, make it to become multistage draining valve.

Certainly, multistage pressure guide drainage valve of the present invention can also have multiple conversion and remodeling, is not limited to the concrete structure of above-mentioned embodiment, as controlled the change of float transmission mechanism mode, all changes of diaphragm seal frame mode etc.In a word, the protection domain of flow guide bed pan of the present invention also should comprise those apparent exchanges to those skilled in the art, substitutes and change shape.
