Description

A kind of fluid feed system

Technical field

The invention belongs to valve field, more particularly to valve element technical field used in tap, more particularly to a kind of single handle is double Interlink water valve core.

Background technology

Valve for controlling fluid by state, such as is controlled as one of control device the most frequently used in production and living The fluid flow that the fluid type that passes through, control pass through.Ordinary people understands, be in the most contact is exactly water used in daily life Tap.Tap by opening ways be commonly divided into spirally, Wrench-type, lift open formula and induction type etc..Spiral handle passes through When screwing opening, and opening, many circles are rotated, by the number of turns adjusting water outlet flow screwed, it is more to screw the number of turns, flow It is bigger；Wrench-type handle is opened by horizontally rotating, and water flow is controlled with the angular dimension of unlatching, opening angle is bigger, Flow is bigger, and maximum angle is typically 90 °；Lift is opened formula handle and opened by upper lift vertically, equally, with the angular dimension of unlatching come Water flow is controlled, opening angle is bigger, and flow is bigger, and maximum angle is typically smaller than 45 °；As long as inductive water tap handle is stretched To under tap, by sensing automatic outletting, but generally water flow is fixed, it is impossible to adjusted.

Single handle duplex valve element is most common faucet valve core, especially potsherd list handle duplex valve element in life, production, It has been the valve core for cold/hot water faucet generally used in current kitchen, toilet.Valve element includes the sealing that stator and moving plate are constituted Piece, the control handle that operating mechanism slides for the opposing stator sealing of control moving plate, stator is provided with cold inlet opening, hot inlet opening And apopore, moving plate is provided with passage, and the passage is used to connect hot inlet opening when moving plate opposing stator is sealed and slided and gone out Water hole, either cold inlet opening and apopore or hot inlet opening, cold inlet opening and apopore.To lift the single handle dual valve for the formula that opens Exemplified by core, the domestic usual operation standard of China is that it is that apopore only goes out hot water that control handle, which turns left to extreme position near zone, Now apopore is only connected with hot inlet opening by passage；Control handle turn right to extreme position near zone be apopore only go out it is cold Water, now apopore only connected with cold inlet opening by passage；And it is then therebetween the mixed aqua region of hot and cold water mixing, this When apopore simultaneously connected with hot and cold inlet opening by passage, control handle is more toward left-handed, hot water ratio in hot and cold water inlet ratio Bigger, water is warmmer, until becoming pure hot water；Control handle is more toward dextrorotation, and cold water ratio is bigger in hot and cold water inlet ratio, and water is got over It is cold, until becoming pure cold water.And in control handle left rotation and right rotation, pass through the upper upper lift angular adjustment for lifting control handle going out this moment Water-carrying capacity, angle more big flow is bigger.

Potsherd list handle duplex valve element has that hot and cold water is easy to adjust flexibly, the smooth light and handy, potsherd of control handle operation (Gu Stator, moving plate) good seal and the advantages of valve element long lifespan.

However, how to change regardless of the control mode of existing various valves, it is particularly various used in daily life Tap, it only has two firm discharge adjusting positions, closes the closed position and the accommodation limit position that water flow is maximum of water Put, only in the two positions, user easily promptly can be adjusted operating mechanism in place, correspondence Flow-rate adjustment to fixation Size (is exactly to be lifted on closed position, and handle to the max-flow of upper limit (UL) point for most common single handle duplex valve element Measure position).And user will be obtained when closing to any flow between maximum stream flow, then slow carefully regulation operation is needed Mechanism could be realized (for most common single handle duplex valve element, it is necessary to regulation handle angle above and below repeatedly).But it is actual In life, the flow that user needs exactly is closed to a certain flow between maximum stream flow again, spends longer in user When time adjusts operating mechanism to required flow, the waste of many water resources is already caused in this period.

Meanwhile, in routine use, different use water spot/use occasions, is different for suitable water flow：Than Such as, it is that some flow A is generally proper that toilet, which is washed one's hands, the demand of cleaning can be met, while not resulting in the mistake of water again It is waste more；And it is probably then flow B proper that vegetables and fruits are washed in kitchen, living balcony laundry clothes are again that flow C is proper.And lead to Chang Eryan, between flow A, B, C and is differed, and user is under various different water spot/use occasions, it is impossible to quickly and accurately By operating mechanism regulation in place, the flow control needed for realizing.

In addition, for by Valve controlling thermal fluid flow, during the common hot water flow for control, correspondence has one and carried The hot fluid feeding mechanism of heat donor fluid (such as hot water), the hot fluid outlet ports of hot fluid feeding mechanism and the hot-fluid of valving Body arrival end is connected, and common hot fluid feeding mechanism is various water heaters, such as gas heater, electric hot water in daily life Device etc..In hot fluid feeding mechanism (such as water heater) to having one section of pipeline between valve, when hot water is using finishing, shutoff valve After door, the hot water retained in this section of pipeline and in water-heater water tank can not be utilized, and heat is wasted.Meanwhile, hot water The hot water retained in device water tank also results in the rapid generation of water tank incrustation scale, reduction water heater service life and the efficiency of heating surface.This Outside, during using hot water, pause is closed after valve using in the case of hot water, has very hyperpyrexia because water tank still absorbs Measure, now the high heat will still continue to that the hot water retained in water tank is continued to heat, and now the water in water tank can be heated to Original control temperature is significantly higher by, valve is now opened when being continuing with hot water, when retaining hot water from valve in this part water tank When door is released, user can substantially have found that this part coolant-temperature gage is significantly too high, influence usage experience, even cause to scald when serious Wound.Moreover, for common single handle duplex valve element, hot water control area is in left side, and cold water control area is on right side, heat After water is using finishing, user directly pushes handle can close hot water on earth；But in daily life, user is often closing Forget rotatable handle after hot water to cold water control area, caused that during upper lift handle Open valve next time heat can be directly initiated Hydrophone, if now and not needing hot water, will result in the waste of hot water.

Meanwhile, at present by Valve controlling fluid, hot fluid is particularly controlled, is supplied for the fluid that fluid is provided for valve Device is answered, the hot fluid feeding mechanism of hot fluid is particularly supplied, because hot fluid (such as hot water) temperature can only be in hot fluid Feeding mechanism (such as water heater) carries out centralized Control, and the temperature of each difference water spot is all consistent, it is impossible to by each With the fluid supply temperature of the Valve controlling hot fluid feeding mechanism (such as water heater) of water spot.And in daily life, in difference With water spot/use occasion, the requirement to water temperature is different.Such as, it is that some temperature A is generally proper that toilet, which is washed one's hands,； It is probably temperature D proper, it is again that temperature E is proper that bathroom, which is had a bath, and kitchen is washed the dishes.Under the prior art, user Hot fluid supply temperature continually can only be adjusted repeatedly in hot fluid feeding mechanism (such as water heater), or pass through on valve Substantially regulation cold water, hot water mixing ratio control leaving water temperature roughly.

China's scarcity of fresh water resources, with water resource worsening shortages, kitchen, toilet etc. are cured with water spot using water wisely problem Plus it is prominent, in the urgent need to water-saving result is more preferable, use more convenient, flexible valve element.

The content of the invention

An object of the present invention is：A kind of fluid feed system is provided, its valving is conducive to saving valve dress Put the fluid passed through；Meanwhile, the valving can be that fluid supply apparatus, particularly hot fluid feeding mechanism provide feedback letter Breath, is conducive to the control to fluid supply apparatus by valve realization, particularly the hot fluid of hot fluid feeding mechanism is supplied The control of temperature.

The object of the invention is realized by following technical proposals：

A kind of fluid feed system, including at least one valving, and fluid supply apparatus, fluid supply apparatus Fluid inlet end of the fluid issuing respectively with each valving is connected, and controls fluid intake according to the operating mechanism of valving Flow is held to control the fluid supply situation of fluid supply apparatus, the operating position of the operating mechanism of the valving removes valving Outside the closed position that the flow of fluid outlet is zero, also with the different limit stop position of at least two flow.

In this patent, the limit stop position refers to that operating mechanism adjusts the operable physics limit position of flow.Should Valving and its limit stop position are not limited to various types, for different valve types, its limit stop position type Formula is different.As an example, (being typically single handle dual valve) for the tap of formula opening ways is opened in lift, lift is opened formula handle and led to Cross vertical upper lift to open, water flow is controlled with the angular dimension lifted, when angle is zero, tap is closed, now handle Position is lower position-arresting, and handle, when being located at left side extreme position, this is the limit stop position (minimum stop bit) of lower-left stop bit, and When handle is located at right limit position, this is the limit stop position (minimum stop bit) of bottom right stop bit；And when lifting angle maximum (now usual maximum flow), now handle position be upper position-arresting, and handle be located at left side extreme position when, this be upper left stop bit Limit stop position (maximum stop bit), and handle be located at right limit position when, this be upper right stop bit limit stop position (maximum stop bit).Similarly, Wrench-type handle is opened by horizontally rotating, and water flow is controlled with the angular dimension of unlatching, Opening angle is bigger, and flow is bigger, and angle is that 0 ° this point (being usually closed position) is the limit stop position of left stop bit (minimum stop bit), and another maximum point (being usually maximum stream flow position) of angle for right stop bit limit stop position (most Big stop bit).

Alternatively, the fluid inlet end of valving is divided into first fluid arrival end and second fluid arrival end, the limit Stop position includes the maximum stop bit of first fluid, and first fluid minimum stop bit, second fluid maximum stop bit, second fluid minimum is stopped Position；The operating position of the operating mechanism of the valving is also included between the maximum stop bit of first fluid and the maximum stop bit of second fluid The maximum stop bit in intermediate region, and intermediate region minimum between the minimum stop bit of first fluid and the minimum stop bit of second fluid stops Position.In the program, (single handle dual valve is typically) for the tap of formula opening ways is opened in lift, the pole of foregoing lower-left stop bit It is the minimum stop bit of first fluid to limit stop position, and the limit stop position of bottom right stop bit is the minimum stop bit of second fluid；Stop upper left The limit stop position of position is the maximum stop bit of first fluid, and the limit stop position of upper right stop bit is the maximum stop bit of second fluid.

Alternatively, the maximum stop bit of first fluid is different with the maximum stop bit flow of second fluid, first fluid minimum stop bit, The operating position of at least one operating mechanism in the minimum stop bit of second fluid minimum stop bit and intermediate region is closed position.

Alternatively, the operation of at least one operating mechanism in the minimum stop bit of first fluid minimum stop bit, second fluid The flow of the valving fluid outlet of position be more than zero, except aforementioned flow be more than zero operating mechanism operating position it Outside, at least one secured adjusted in the minimum stop bit of first fluid, the minimum stop bit of the minimum stop bit of second fluid and intermediate region Position is closed position.

Alternatively, valving is single handle dual valve.

First, alternatively, the valving of fluid feed system is the valving of unilateral constant flow：

Valving, be included in fluid by when control valve gear of the fluid by state, and by its operating space Operation is carried out in domain and realizes the operating mechanism of foregoing control, valve gear have first fluid arrival end, second fluid arrival end and Fluid outlet, the operating area of operating mechanism is divided into the mixability regulation of regulation first fluid and second fluid mixability Region, and adjust the flow regulation zone of its fluid outlet flow, mixability regulatory region in mixability adjustment region Domain includes the first fluid region that the fluid outlet that must have only goes out first fluid, and fluid outlet only goes out the of second fluid Two fluid masses, and the fluid issuing that can have bring out the mixing region of first fluid and second fluid fluid-mixing, operate machine Structure is more than zero in the flow of the minimum stop bit of the flow regulation zone in first fluid region, and in the flow tune in second fluid region The flow for saving the minimum stop bit in region is equal to zero.

In the present invention program, the first fluid, second fluid can be the fluid of identical type or not of the same race The fluid of class, such as respectively water and other fluids, or be all water, etc.；Meanwhile, can be the one species of different conditions Fluid or the one species fluid with state, such as respectively cold water and hot water are all either cold water or are all Hot water.It is described hot and cold, only between the two comparatively, absolute sense is not had, hot water is only relative cold water temperature Du Genggao water.Cold water typically refers to normal-temperature water, and most common is exactly the running water of daily life, meanwhile, cold water can also be The lower water of obtained temperature that normal-temperature water is further cooled.And hot water, then it is commonly referred to as heating further to normal-temperature water and carries The water of high-temperature.In addition, first fluid, second fluid, which are used only for difference, defines two-way fluid, it is not absolute definition, than Such as, can be using cold water as first fluid for cold water and hot water, and hot water turns into second fluid relatively, in turn Can be using hot water as first fluid, and cold water is naturally relative as second fluid.In the mixability adjustment region, mixing Region is optional, i.e., fluid outlet can only go out first fluid or second fluid, and can not go out fluid-mixing；And mix journey In degree, when first fluid accounting 100% and during second fluid accounting 0%, i.e., fluid outlet only goes out the first-class of first fluid Body region；In turn, when first fluid accounting 0% and during second fluid accounting 100%, i.e., fluid outlet only goes out second fluid Second fluid region.The flow regulation zone refers to that the operable physics of operating mechanism regulation flow is interval, including must have Minimal adjustment position (minimum stop bit/minimum stop position), adjustment region, and (maximum is stopped for the maximal regulated position that can have Position/maximum stop position)；Similarly, the control handle implantation site refers to that control handle adjusts the operable physical location of flow； (single handle dual valve is typically for the tap of formula opening ways is opened in lift), and lift is opened formula handle and opened by upper lift vertically, Water flow is controlled with the angular dimension lifted, when angle is zero, tap is closed, and now handle position is lower position-arresting, is Minimal adjustment position (minimum stop bit/minimum stop position)；And lift angle it is maximum when (now usual maximum flow), now hand Handle position is upper position-arresting, is maximal regulated position (maximum stop bit/maximum stop position).Similarly, Wrench-type handle passes through water Flat Unscrew, water flow is controlled with the angular dimension of unlatching, and opening angle is bigger, and flow is bigger, and angle is this of 0 ° Individual point (being usually closed position) is minimal adjustment position (minimum stop bit/minimum stop position), and another of angle maximum Point (being usually maximum stream flow position) is maximal regulated position (maximum stop bit/maximum stop position).

The present invention program, particularly relatively existing various valves, relatively existing common single handle duplex valve element, its flow Adjustment region is except possessing the null closed position of flow of the shared minimum stop bit of prior art, and the position of regulated value greatly Outside, it is also equipped with the minimum stop bit of the extreme position of a firm discharge between the two.The difference of itself and existing valve exists In, existing valvular operating mechanism is equal to zero in the flow of the minimum stop bit of the flow regulation zone of first and second fluid mass, I.e. the two positions are closed position, and one of them is then changed to the control bit of particular flow rate of the flow more than zero by this patent Put.Such as it is the flow A for being adapted to wash one's hands by the flow design of this minimum stop bit, operating mechanism is easily and rapidly placed in the position Put the flow that can obtain being adapted to wash one's hands.By taking common single handle duplex valve element as an example, the handle of existing single handle duplex valve element is most left Side most descend operating position (be usually first fluid region, the closed position of such as hot water) and rightmost most descend operating position (be usually second fluid region, the closed position of such as cold water) is all closed position, and this patent handle is placed in it is leftmost It is the particular flow rate A that can obtain being adapted to wash one's hands most to descend operating position, and by handle be placed in rightmost most descend operating position then and Existing single handle duplex valve element is equally closed mode；Vice versa, handle can also be placed in rightmost most by this patent Lower operating position is the particular flow rate A that can obtain being adapted to wash one's hands, and handle is placed in and leftmost most descends operating position then and existing It is equally closed mode to have single handle duplex valve element.

Based on previous designs, by taking daily water consumption as an example, the present invention can design tool according to different use water spot/use occasions There is the minimum stop bit of difference of flow regulation zone of the operating mechanism in first fluid region, such as form flow correspondence respectively and be adapted to Flow A that toilet is washed one's hands, it is adapted to the series that the flow B of vegetables and fruits, the flow C for being adapted to living balcony laundry clothes, etc. are washed in kitchen The valve of model, is respectively applied to each personal water spot/use occasion, realizes that the most hommization used and judicial convenience are maximized simultaneously Water saving.

Further, because the valve of the present invention is except with closed mode and maximum stream flow state, also with one The particular state of particular flow rate, then the particular state of this particular flow rate can just turn into identification signal/control of the valve Signal, fluid supply apparatus can recognize the valve according to the particular flow rate information, so that correspondence takes corresponding control operation. , first will operation when user washes one's hands in toilet so that hot fluid feeding mechanism (such as water heater) carries out water temperature control as an example Mechanism passes directly to the particular state, starts water heater, and water heater can detect (sensing) and arrive specific with the valve of the toilet Signal specific (such as flow value or dynamic pressure/static pressure ratio or dynamic pressure/full pressure ratio or static pressure/dynamic pressure ratio corresponding flow A Deng), the valve for being identified as toilet is carrying out handwash operation, directly adjusts leaving water temperature to the prefabricated suitable temperature washed one's hands A；And operating mechanism is passed directly to the particular state by user first when being washed the dishes in kitchen, equally, start water heater, water heater The particular flow rate D of the valve in kitchen signal specific is received, the valve for being identified as kitchen is carrying out dishwashing operations, will directly go out Coolant-temperature gage is adjusted to the prefabricated suitable temperature D washed the dishes；Likewise, it is also such that bathroom, which is had a bath,.

Meanwhile, the hot fluid feeding mechanism (such as gas heater) of prior art has one and closes its heating system Minimum flow, the water heater will close heating system (flame-out) during less than the minimum flow, and of the invention operating mechanism can be with It is more than zero in the flow of the minimum stop bit of the flow regulation zone in first fluid region (hot water region), when this minimum stop bit When flow is less than the minimum flow that water heater is closed, heating system will be closed in water heater, and valve is to pipeline between water heater And retaining hot water and still can be discharged from valve in water-heater water tank, follow-up cold water also and then can enter water tank, cold But water tank, thus, had both realized making full use of for hot water, and water tank fouling is solved again and hot water is continuing with, part hot water temperature The problem of degree is significantly higher.

Alternatively, operating mechanism the maximum stop bit of the flow regulation zone in first fluid region flow, and The flow of the maximum stop bit of the flow regulation zone of two fluid masses is unequal.In the program, quick-opened valve core be life, production in Common faucet valve core, especially potsherd quick-opened valve core, have been the faucet valve cores generally used at present.Potsherd is opened soon Valve element has the advantages that smooth light and handy, potsherd (the stator, moving plate) good seal of control handle operation and valve element long lifespan.It is another Aspect, because control handle is smooth light and handy, easily maximum is reached during unlatching by water-carrying capacity, was formed mass-flow and is caused waste；Together When, because control handle Flow-rate adjustment stroke is shorter, it is unfavorable for more accurately controlling water-carrying capacity.That is, in daily life, although water Tap can obtain maximum stream flow when control handle is opened into maximum, but under most service conditions, all without using most Big flow, even if needing big flow to use, generally also one when young in one big flow of maximum stream flow.And the existing fire hose Head promptly can not all be adjusted control handle to the position, and can only slowly adjust could obtain the flow value.And in this patent The selection scheme in, the flow difference of two maximum stop bits can be while different fluid use demand be met, can be most Fluid is saved to limits, can be further according to the different maximum stream flow of the different choice of use demand.

Foregoing main scheme of the invention and its each further selection scheme can form multiple schemes with independent assortment, be this The scheme that invention can be used and is claimed：Such as the present invention, (such as selection 3,4,5 and A, B, C are conflict for each non conflicting selection Selection, can not combine each other, and can only with other main schemes or selection combine) selection between or between main scheme arbitrarily Combination, etc., those skilled in the art can understand there is a variety of after the present invention program is understood according to prior art and common knowledge Combination, is claimed technical scheme of the invention, exhaustion is not done herein.

Beneficial effects of the present invention：Valving, is conducive to saving the fluid that valving passes through；Meanwhile, valve dress It can be that fluid supply apparatus, particularly hot fluid feeding mechanism provide feedback information to put, and be conducive to realizing convection current by valve The control of body feeding mechanism, is particularly the control to the hot fluid supply temperature of hot fluid feeding mechanism；And supplied when with hot fluid When answering the device to use cooperatively, the normal of the hot fluid feeding mechanism can be conducive to use.Specifically：

(1) valve element critical condition is set, separates big flow and low discharge.By set critical condition and will economize on water valve element stream Amount adjustment region is divided into big flow adjustment region (being more than critical condition flow) and (is less than critical condition with low discharge adjustment region Flow), facilitate the suitable flow regulation zone of water user's selection or critical condition, beneficial to using water wisely.

(2) easily operating method, water saving valve element inserts control handle the operation of critical condition (saving state), similar general Port valve core inserts control handle the operation of closed mode, and its operating method is simple, quick.Increase control handle regulation stroke, be beneficial to Adjust flow.The one-part form regulation stroke spread of common valve element control handle is adjusted into stroke for the two-period form of water saving valve element, due to Regulation stroke spread causes control handle Flow-rate adjustment more accurately, conveniently.

(3) common valve element operating method is taken into account, and retains common valve element advantage.Valve element economize on water using similar with common valve element Unlatching, shutoff operation method, and the advantage of common valve element is remained, for example, hot and cold water is easy to adjust flexibly, control handle operation The advantages of smooth light and handy and valve element long lifespan.Compared with the present invention：There is a kind of use flexible member that the valve of segmentation gear is set Core, when manipulating this many gear valve elements, it is necessary to which the conversion between gear can be carried out by suppressing gear elastic force, had both lost control The smooth light and handy operating handle of handle, shortens valve element service life again.

(4) water saving is saved again.Water saving valve element is used and (there is single heat pattern critical condition), not only beneficial to using water wisely, And hot water open frequency can be reduced and the energy is saved.Reason is as follows：Due to single heat pattern lower position-arresting of above-mentioned water saving valve element For critical condition, control handle is inserted other pattern lower position-arrestings (for example, single chill formula by guiding water user when closing water saving valve element Lower position-arresting), using that just can avoid control handle inserting single heat pattern adjustment region as far as possible during cold water, so as to reduce unlatching hot water Frequency simultaneously reduces energy waste.

(5) normally used beneficial to water heater.For the cold and hot water supply system using gas heater as thermal source, using with single heat The water saving valve element of pattern critical condition, and the flow value for valve element list heat pattern critical condition of economizing on water is set smaller than gas and hot water The minimum closing flow value of device, can not only save hot water and be also especially beneficial gas heater and normally use.Its mode of operation is： (a) using during hot water, if not needing big flow hot water, control handle can be inserted to low discharge adjustment region (or critical shape State).On the one hand, because low discharge adjustment region is less than critical condition flow, i.e., less than the minimum closing flow of gas heater, combustion Gas water heater extinguishing does not consume combustion gas；On the other hand, it is cold because water saving valve element is in low discharge adjustment region (or critical condition) Hot-water heating system (in hot water line and gas heater internal reservoir) still has the outflow of low discharge hot water to meet short time hot water need Ask.(b) when closing hot water, control handle is inserted by (single heat pattern or cold and hot mixed mode) big flow adjustment region in advance Big flow hot water, is switched to low discharge hot water by (single heat pattern) low discharge adjustment region or critical condition, finally will control Handle inserts closed mode by low discharge adjustment region (or critical condition).Aforesaid operations can not only save hot water, combustion gas, may be used also Effectively to prevent that gas heater encrustation (save state lower water-heater and stop working, and its internal hot-water is continued to flow out for making by valve element With while cold water enters water heater and reduces water heater temperature), beneficial to keeping the normal heat transfer efficiency of water heater and extend to use the longevity Life.

2nd, alternatively, the valving of fluid feed system is the valving of bilateral constant flow：

A kind of valving, be included in fluid by when control valve gear of the fluid by state, and by its grasp Make to carry out the operating mechanism that foregoing control is realized in operation in region, valve gear has first fluid arrival end, second fluid entrance End and fluid outlet, the operating area of operating mechanism are divided into the mixability of regulation first fluid and second fluid mixability Adjustment region, and the flow regulation zone of its fluid outlet flow is adjusted in mixability adjustment region, mixability is adjusted Section region is divided into the first fluid region that fluid outlet only goes out first fluid, and fluid outlet only goes out the second of second fluid Intermediate region between fluid mass, and first fluid region and second fluid region, the fluid outlet of the intermediate region Do not go out fluid, or bring out for fluid issuing the mixing region of first fluid and second fluid fluid-mixing, operating mechanism is the First, the flow of the minimum stop bit of the flow regulation zone of two fluid masses is all higher than zero, and in the Flow-rate adjustment area for mixing region The flow of the minimum stop bit in domain is equal to zero.

In the present invention program, the first fluid, second fluid can be the fluid of identical type or not of the same race The fluid of class, such as respectively water and other fluids, or be all water, etc.；Meanwhile, can be the one species of different conditions Fluid or the one species fluid with state, such as respectively cold water and hot water are all either cold water or are all Hot water.It is described hot and cold, only between the two comparatively, absolute sense is not had, hot water is only relative cold water temperature Du Genggao water.Cold water typically refers to normal-temperature water, and most common is exactly the running water of daily life, meanwhile, cold water can also be The lower water of obtained temperature that normal-temperature water is further cooled.And hot water, then it is commonly referred to as heating further to normal-temperature water and carries The water of high-temperature.In addition, first fluid, second fluid, which are used only for difference, defines two-way fluid, it is not absolute definition, than Such as, can be using cold water as first fluid for cold water and hot water, and hot water turns into second fluid relatively, in turn Can be using hot water as first fluid, and cold water is naturally relative as second fluid.In the mixability adjustment region, mixing Region is optional, i.e., fluid outlet can only go out first fluid or second fluid, and can not go out fluid-mixing；And mix journey In degree, when first fluid accounting 100% and during second fluid accounting 0%, i.e., fluid outlet only goes out the first-class of first fluid Body region；In turn, when first fluid accounting 0% and during second fluid accounting 100%, i.e., fluid outlet only goes out second fluid Second fluid region.The flow regulation zone refers to that the operable physics of operating mechanism regulation flow is interval, includingMust have 'sMinimal adjustment position (minimum stop bit/minimum stop position), adjustment region,AndCan have(maximum is stopped for maximal regulated position Position/maximum stop position)；Similarly, the control handle implantation site refers to that control handle adjusts the operable physical location of flow； (single handle dual valve is typically for the tap of formula opening ways is opened in lift), and lift is opened formula handle and opened by upper lift vertically, Water flow is controlled with the angular dimension lifted, when angle is zero, tap is closed, and now handle position is lower position-arresting, is Minimal adjustment position (minimum stop bit/minimum stop position)；And lift angle it is maximum when (now usual maximum flow), now hand Handle position is upper position-arresting, is maximal regulated position (maximum stop bit/maximum stop position).Similarly, Wrench-type handle passes through water Flat Unscrew, water flow is controlled with the angular dimension of unlatching, and opening angle is bigger, and flow is bigger, and angle is this of 0 ° Individual point (being usually closed position) is minimal adjustment position (minimum stop bit/minimum stop position), and another of angle maximum Point (being usually maximum stream flow position) is maximal regulated position (maximum stop bit/maximum stop position).There are two kinds of shapes intermediate region State, a kind of is that the fluid outlet of the intermediate region does not go out fluid, another to bring out first fluid and second for fluid issuing The state of body fluid-mixing, is defined as mixing region.

The present invention program, particularly relatively existing various valves, relatively existing common single handle duplex valve element, its flow Adjustment region is except possessing the null closed position of flow of the shared minimum stop bit of prior art, and the position of regulated value greatly Outside, it is also equipped with the minimum stop bit (firm discharge of two fixed positions of two extreme positions of firm discharge between the two Can be identical, also can be different, preferably different).The difference of itself and existing valve is, existing valvular operating mechanism first, The flow of the minimum stop bit of the flow regulation zone of two fluid masses and Mixed Zone is equal to zero, i.e., these three positions are to close Closed position, and the minimum stop bit of the wherein flow regulation zone of first and second fluid mass is then changed to flow more than zero by this patent Particular flow rate control position.When the firm discharge of both of the aforesaid fixed position is different, such as by the two minimum stop bits Flow separately design to be adapted to the flow A that washes one's hands and be adapted to the flow B that washes vegetables and fruits, operating mechanism is easily and rapidly placed in pair Position is answered to obtain being adapted to wash one's hands or washing the flow of vegetables and fruits.By taking common single handle duplex valve element as an example, existing single handle dual valve The handle of core is leftmost most to descend operating position (being usually first fluid region, the closed position of such as hot water) and rightmost is most Lower operating position (being usually second fluid region, the closed position of such as cold water) is all closed position, and this patent puts handle Most descend operating position to be the particular flow rate A that can obtain being adapted to wash one's hands in leftmost, and handle is placed in the most lower behaviour of rightmost It is that can obtain being adapted to the particular flow rate B for washing vegetables and fruits as position, and region therebetween most descends operating position (usually to mix Region is closed, such as the closed position for the mixed water that hot and cold water is mixed) it is then closed mode as existing single handle duplex valve element；In turn Similarly, what handle can also be placed in rightmost by this patent most descends operating position to obtain being adapted to the particular flow rate for washing fruits and vegetables B, and by handle be placed in it is leftmost most descend operating position then to obtain the particular flow rate A for being adapted to wash one's hands, and middle most lower operation Position is then closed mode as existing single handle duplex valve element.

Based on previous designs, by taking daily water consumption as an example, the present invention can design tool according to different use water spot/use occasions There is the minimum stop bit correspondence flow of difference of flow regulation zone of the operating mechanism in first fluid region, such as form flow respectively Flow A, the flow C that the flow B of vegetables and fruits is washed in suitable kitchen, suitable living balcony laundry takes that corresponding suitable toilet is washed one's hands, etc. Deng serial model No. valve, be respectively applied to each personal water spot/use occasion, realize that the most hommization used and judicial convenience are same When maximize water saving.Particularly, the valve of this patent simultaneously there are two particular flow rates, can correspond to respectively two kinds with water spot/ Use occasion.
