Abstract
The utility model belongs to a wash hand valve with automatic delay time and water saving, which connects the valve, in particular to a water valve with water outlet, the utility model water receptacle of water inlet, the water outlet of container can be pinhole, variable flow tube, siphon or their combination. said as diagram 3. If opening the valve, the water level can rise to siphon (9) top, water can outflow from siphon, now to shut valve water will outflow continuously, because the hydraulic pressure in container has greatly decreased, flow rate is very low, the water use rate improved with remarkable water saving; if the opening valve is prolonged, water will overflow upper opening of variable flow tube (2) and flow out rapidly. Therefore, washing hand after closing valve cannot touch the valve body, use the electronic automatic wash hand valve can supply water as require, substitute common water tap. The water tap and delay time, variable flow and decreased hydraulic mechanism without movable member, only with few parts, so the costs and failure rate are very lower.
Description
(1), technical field
The utility model belongs to water-saving gate valve series products in a kind of daily life, especially a kind of automatic time delay water-saving washing valve.
(2), background technique
At present, wash one's hands or the common feature that washes with gate valve is, the water intake of valve body links to each other with the water source, and current are directly discharged by water outlet through valve; The keying of valve has determined having or not of water outlet current.Washing valve is not delayed time and is discharged water and the time-delay two big classes that discharge water.
Do not delay time, the quick open type water valve that ceramic plate sealing is arranged also has up-to-date " self-closing link water valve " (patent No. ZL02283997.6) that grows up on ceramic plate seal valve basis to have more manually (or foot-propelled) and opens that valve discharges water, hand goes (or pin leaves) just to lean on a spring band movable valve to close.The shortcoming of washing valve of not delaying time is: after washing hand, for closing gate valve contacts handle on the valve again, the sensation of " having made dirty again " is just arranged psychologically.Self acting stop valve exists hand anhydrous once leaving equally, can not solve the problem of " having made dirty again ".
The main feature of the washing valve in people's ideal is, after hand left the gate valve handle, the water that also should continue for some time flowed out, so that the foul in that imagination is cleaned when hand contacted valve body.At this requirement, the automatic washing valve of multiple time-delay closing has appearred, automatic two classes of mechanical delay and electronics are arranged.
The subject matter of this two classes time-delay valve is at present:
Mechanical delay is afraid of to be stopped up by foreign material in the water as the big time-delay aperture of needle point most, though have be covered with filter screen at pin hole, particulate and the calcium ions and magnesium ions that is dissolved in the water still can be deposited on hole wall, and its obstruction the most at last; When using in public places, very easily turned round bad carelessly.
The valve body of electronics self-acting valve has motor type, electromagnetic valve type, sentinel valve formula; The above two power consumptions are big, though though the pulsed power consumption is very little and electronic circuit modularization, but also the same with the above two---the movable part of spool, the valve micropore of opening in the runner more easily break down, all need uninterrupted power consumption in 24 hours all the year round, have a power failure or battery exhausts soon, battery altering etc., can cause trouble, photoelectric probe is also easily stained.
The overall working life of this two classes valve is not long, and particularly public place in the open because Environmental Conditions is abominable, more is prone to problem.Their common drawback is, all there is the movable part inside, and structure is complicated, part is more, cost is also high.
As washing valve, will hand-wash under the clean prerequisite in assurance, it is just good more that obvious, water consumption is saved more.And general washing valve---no matter be that delayed type also is non-delayed type, electronic type or mechanical type all are to be in the hard switching state, or standard-sized sheet, or complete shut-down.Because tap water pressure is higher, in case drive valve, drip for each, the current of going out are just extremely short in the time of contact on hand at a high speed, and it is underground that most of water even at all do not touch have just dropped on hand, and the utilization ratio of water is extremely low, wastes very big.Improve the utilization ratio of water, just should increase each time of contact with hand of dripping, reduce the flow velocity of water, the pressure that this just need reduce water greatly accomplish to do little by little without a break, and present washing valve does not have this function.
The purpose of this utility model will solve above variety of problems with " automatic time delay water-saving washing valve " exactly, and it can be after gate valve be closed, and discharges water at a slow speed with very low hydraulic pressure time-delay, again can be when needed, discharge water at a high speed; Simple in structure, firm, cost is low, and not electric, rate of fault is low.
Do not have this device in the market, consulted Chinese patent in recent years, also not seeing has the innovation knot identical with the utility model
(3) summary of the invention
The utility model purpose realizes by the following method:
With a sealing water container that has water intake and water outlet, internal tank has the unsteady flow pipe of a both ends open, and unsteady flow pipe end opening stretches out from the water container bottom, and is fixed on the container wall, is water-stop with container wall and is connected; The high water level place that places in the water container suitable for reading of unsteady flow pipe, the tube wall of unsteady flow pipe has one or more apertures from the lower end, and makes the water intake area of total water flowing area of aperture less than container; Like this, after the container water intake connects gate valve, if open valve water inlet, water-filling in container just, the water of big flow is full of container very soon, water in the container, can only flow out from the aperture of unsteady flow tube wall lower end at first, when water level continued to rise to container top but surpasses unsteady flow pipe suitable for reading, if closing gate valve, then water will slowly flow out from aperture, this just can be for washing one's hands, and container has just become the time-delay water outlet device; Because gate valve is closed, and the suitable for reading and atmosphere of unsteady flow pipe communicates, so the water pressure in the container is extremely low, and flow velocity is very slow, the time that continues outflow is also just longer, the actual measurement proof, for a little container, the time that continues to flow out can accomplish that the several seconds was to tens of seconds, and common people wash one's hands and were no more than for 10 seconds usually, can replace existing complicated needle point aperture time-delay valve and electronics self-acting valve fully, and sluggish flow prolongs the time of contact of water and hand, improved the utilization ratio of water; Confirm that through preliminary test the water consumption that this device is washed one's hands only is about 1/5th of traditional approach, just the utilization ratio of water has improved about five times.
When needs discharge water in a large number, only need and to open the time lengthening of gate valve, when the water level in the container rises to above unsteady flow pipe suitable for reading, water is just directly from inflow suitable for reading, end opening flows out, because the main latus rectum of unsteady flow pipe is close with the latus rectum of gate valve water channel, high-velocity flow will keep original pressure and flow, and this has just played the effect that discharges water fast.
In brief, if it is very short to open time of valve, just can utilizes the water that oozes, the both hands washes clean needn't be touched valve body again; If opening valve time is long slightly, water will flow out at a high speed.
Generally speaking, the both hands washing finishes, and water also drops down to the greatest extent in the container, can stalk off; If do not clean, can have again.The quick exhalant canal in the top of unsteady flow pipe, not only can open upwards, also can open at it radially on the tube wall in the top axle of unsteady flow pipe.If the pure function of only need washing one's hands does not need the function that discharges water fast, just can cancel the interior unsteady flow pipe of container, or make the internal diameter of unsteady flow pipe very little.Ostium excurrens also can not opened on unsteady flow tube wall face, and directly opens on the wall of container bottom.No matter be out a hole or several hole, total its water outlet sectional area, should be much smaller than the water intake area, this just has the effect of time-delay.
Though the area of ostium excurrens is very little, more many greatly than the pin hole latus rectum of pin hole time-delay valve, therefore extremely difficult the obstruction.The diameter of supposing the time-delay pin hole is 0.3MM, supposes only 2.5MM of the utility model aperture again, and then its former latus rectum is
1/4∏D
2＝0.25×3.14×0.3
2＝0.071MM
2
The latter's latus rectum then is
1/4∏D
2＝0.25×3.14×2.5
2＝4.91MM
2
The latter is bigger 69 times than the former.That is to say that if water quality is identical, suppose that the former is dissolved in the time that the calcium ions and magnesium ions sediments in the water stopped up and needs 3 years, the latter then takes 69 times * 3 years=207 years, just understands and be stopped up by the calcium ions and magnesium ions sediments, is far longer than the working life of valve body itself.
Just in case osculum really is blocked, only need just can remove totally from the outside with safety pin, brush etc., do not need the professional workforce, more need not dismantle any part.More than the advantage of this valve a lot, two minor issues are also arranged, that is exactly: 1, opening the valve water-filling stage to container, just have water to flow out immediately from aperture, though have only short a few second, if but what flow out is the water that contains detergent or disinfector, just very unfortunate; 2, and, before the water in the container is flowed out, excessively flowed out to high speed by low speed, there is not definite signal to send, can not in time close valve, also feel inconvenience.
In order to solve this two problems, can adopt following method: promptly, replace the aperture water outlet with syphon tube.Concrete structure such as Fig. 2: be installed in syphon tube in the container, shape as inverted " U " word, the U-shaped bottom upwards, near the highest water level place in the container, as Fig. 2 (11); Siphonal water sucking mouth (10) downwards, place lowest water level place, container bottom; Siphonal water outlet (4) also downwards, propelling container bottom and being fixed on the container wall, be water-stop with container wall and be connected; Like this, when Open valve, in container during water-filling, water enters from the syphon tube water sucking mouth and slowly rises with water level in the container, have only when water level is raised to and be higher than the syphon tube top duct, water flows out from water outlet---and this has just sent the signal of reminds people throttle down, after valve cuts out, water in the container, just outwards flow out continually by siphonage, till water level is lower than siphonal water sucking mouth, till just water being given out light, because siphonal latus rectum is very little, the effect that has also just had time-delay to discharge water.Syphon tube can be provided with one, also can be provided with many.Siphonal water outlet can be a hole, also can be porous.This siphon arrangement has not only been sent the pass valve signal, and has avoided opening the waste of valve with regard to water outlet, can be made into good washing valve; Yet, it can not discharge water fast.
It also can be discharged water fast, can be with syphon tube and unsteady flow pipe jointing, its structure such as Fig. 3: with the position of syphon tube top (11), be located at the position that is lower than unsteady flow pipe top water intake (5); And siphonal water outlet, both can pass the tube wall of unsteady flow pipe, and be arranged on the water outlet lower end in the unsteady flow pipe, also can directly not pass container bottom wall, independent water outlet, just with the parallel water outlet of unsteady flow pipe by the unsteady flow pipe.Like this, when water level in the container rose, as long as flood the syphon tube top, water just flowed out from syphon tube immediately---and this has just sent the pass valve signal, and this moment, throttle down just can be washed one's hands; If this moment is throttle down not, water level will continue to rise, and when being raised to above unsteady flow pipe top water intake (5), then flow out fast from the unsteady flow pipe.
This structure has just satisfactorily realized: when opening the valve water-filling, outwards do not drop down water, water is full of the back, outwards flows out with low speed water; This just looks like to notify people: " water is full of, could closes valve and washed one's hands! " need not touch valve handle again, wash hand, water has not had yet; As discharging water fast, only need prolong opening valve time and just can accomplish.This just both can replace the automatic washing valve of electronics, again can be when needed, replace closing automatically water tap.
Time-delay container, unsteady flow pipe and siphonal material can be by nonmetal making such as plastics, pottery, glass fibre reinforced plastics; Also can make by metals such as brass, stainless steels; Can also make by composite material.
The profile of time-delay container can be spherical, cylindric or other shape; Can be laterally or be axial with gate valve and be connected.Unsteady flow pipe and syphon tube can be square tube or pipe.
Being connected, can becoming whole and make of container and valve body water outlet, also available thread seal connects, socket, bonding or welding; Can also be between valve body and container, be provided with one upwards, downwards or to the prolongation pipe of other direction, to satisfy certain needs; More than all linkage structures, can be referred to as connector element.
Fig. 4 is between valve (7) and container (1), is provided with the prolongation pipe (12) of a weak point, and it can be installed on the ceramic wash basin easily.Be particularly suitable for toilet, dining room HAND WASH etc.
Fig. 5 is between valve (7) and container (1), is provided with a long prolongation pipe (13), and its valve can be foot-operated, can install on the ground easily.Be particularly suitable for hospital, public lavatory HAND WASH etc., main purpose is water saving.
Though any quick opening valve, all can be used with this unsteady flow time-delay container, but from the water saving viewpoint, obviously self acting stop valve (patent No. ZL02283997.6) is even more ideal---and water, must drive valve, hand is from valve, close automatically, washes hand, water has not just had.
After adopting this device, owing to the time-delay container body structure of its innovation, only form by two or three fixed parts; Can delay time discharges water, and can reduce hydraulic pressure when washing one's hands, does little by little without a break, using water wisely, can change flow again when needed, discharge water at a high speed; Do not have the movable part, do not have the needle point aperture, do not have electronic equipment, do not have what fault; It is compared with the automatic washing valve of infrared rays of band transformer or charged pool, and its part still less, weight is lighter, and price is lower, and reliability is higher, has thoroughly stopped the worry of uninterrupted power consumption in 24 hours all the year round.
Can be combined into polytype time-delay valve with above several time-delay containers, for example:
1. use it to combine, just can constitute that simple " many with the water-saving washing valve of delaying time "---it is applicable to the basin person of discharging water more, the place that the person of washing one's hands is less with common any water tap.
2. use it to combine, can constitute then that " the many water saving with time-delay closed washing valve automatically "---it is applicable to that the person of washing one's hands is many, with the few place of the basin person of discharging water with self-closing link water valve (patent No. ZL02283997.6).
If 3. the macropore on unsteady flow pipe top is dwindled or cancels, or only discharge water with syphon tube, and combine with self acting stop valve, then constituted a kind of more pure washing valve of water saving. i.e. " time-delay economize on water closes automatically washing valve "---it is applicable to that the person of washing one's hands is many, the place that does not almost have with the basin person of discharging water.
4. above three types all can make into foot-operatedly, six types valve has then just been arranged.Can also be combined into more kinds, just series of products.Since the utility model intrinsic, simple and reliable, even, field work,, exempted other automatic washing valve rate of fault height all the year round in the open no matter be extremely hot, severe cold, desert, all can be competent in the rain, needs are the worry of maintenance all the year round.Therefore, this novel time-delay washing valve just might be as ordinary faucet, is widely used in toilet, HAND WASH on all over the world food and drink, public lavatory, street, square, station, harbour, school, family or car, ship, the aircraft; And tourist attractions or the like, condition is good or the place that condition is bad.
