Description

The valving and its fluid feed system of unilateral constant flow
Technical field
The invention belongs to spool technical field used in valve field more particularly to tap, in particular to a kind of single handle is double Interlink water valve core.
Background technique
Valve passes through state as one of control equipment most common in production and living, for controlling fluid, for example controls By fluid type, the fluid flow that passes through of control.Ordinary people understands, be in the most contact is exactly water used in daily life Faucet.Tap is commonly divided into spiral, Wrench-type by opening ways, formula and induction type etc. are opened in lift.Spiral handle passes through When screwing opening, and opening, many circles are rotated, water flow is adjusted by the circle number screwed, it is more to screw circle number, flow It is bigger；Wrench-type handle is opened by rotating horizontally, and water flow is controlled with the angular dimension of unlatching, and opening angle is bigger, Flow is bigger, and maximum angle is usually 90 °；Lift is opened formula handle and is 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 usually less than 45 °；As long as inductive water tap handle is stretched To under tap, by incude automatic outletting, but usually water flow be it is fixed, can not adjust.
Single handle duplex spool is the most common faucet valve core, especially potsherd list handle duplex spool in living, producing, It has been current kitchen, the valve core for cold/hot water faucet that generally uses in toilet.Spool includes the sealing that fixinig plate and movable plate are constituted Piece, operating mechanism are the control handle for controlling the sealing sliding of movable plate opposing stator, and fixinig plate is equipped with cold inlet opening, hot inlet opening And apopore, movable plate are equipped with channel, the channel is to be connected to hot inlet opening when movable plate opposing stator is sealed and slided and go out Water hole perhaps 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 For core, the usual operation standard of the country, China is that it is that apopore only goes out hot water that control handle, which turns left to extreme position near zone, Apopore is only connected to hot inlet opening by channel at this time；It is that apopore is only cold out that control handle, which is turned right to extreme position near zone, Water, apopore is only connected to cold inlet opening by channel at this time；And it is then therebetween the mixed water area of hot and cold water mixing, this When apopore simultaneously be connected to hot and cold inlet opening by channel, 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 flow, angle more big flow are bigger.
Potsherd list handle duplex spool have hot and cold water is easy to adjust flexibly, the smooth light and handy, potsherd of control handle operation (Gu Stator, movable plate) it is sealed and the advantages that the spool service life is long.
However, regardless of the control mode of existing various valves changes, it is especially various used in daily life Tap, only there are two firm discharge adjusting positions, close the closed position and the maximum accommodation limit position of water flow of water It sets, only in the two positions, user can easily promptly be adjusted operating mechanism in place, and corresponding flow is adjusted 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 spool Measure position).And user will obtain when closing to any flow between maximum stream flow, then need slowly carefully to adjust operation Mechanism is just able to achieve (for most common single handle duplex spool, it is necessary to up and down adjustment handle angle repeatedly).But it is practical In life, the flow that user needs exactly is closed to a certain flow between maximum stream flow again, is spent in user longer When operating mechanism is adjusted to required flow by the time, the waste of many water resources is already caused in this period.
Meanwhile in routine use, different uses water spot/use occasion, and suitable water flow is different: ratio Such as, it is that some flow A is usually proper that toilet, which is washed one's hands, that is, is able to satisfy the demand of cleaning, while not will cause the mistake of water again More wastes；And it may be flow B proper that vegetables and fruits are washed then in kitchen, living balcony laundry clothes are again that flow C is proper.And lead to Chang Eryan, not identical between flow A, B, C, user, can not be quickly and accurately under various different water spot/use occasions Operating mechanism is adjusted in place, realizes required flow control.
In addition, for controlling thermal fluid flow by valve, when the common hot water flow for control, corresponding have one and mention 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 to, 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 a Duan Guanlu between valve, when hot water use finishes, closing valve After door, the hot water retained in this section of pipeline and in water-heater water tank is unable to get utilization, and heat is wasted.Meanwhile hot water The hot water retained in device water tank also results in the rapid generation of water tank scale, reduces water heater service life and heating efficiency.This Outside, it in the case that pause is using hot water during using hot water, closes after valve, has very high fever since water tank still absorbs Amount, the high heat will still continue to continue to heat to the hot water retained in water tank at this time, and the water in water tank can be heated at this time It is significantly higher by original control temperature, opens valve at this time when continuing to use hot water, when retaining hot water from valve in this part water tank When door is released, user can obviously have found that this part coolant-temperature gage is significantly excessively high, influence usage experience, even cause to scald when serious Wound.Moreover, hot water control area is in left side, and cold water control area is in right side, heat for common single handle duplex spool After water use, user directly pushes handle can close hot water on earth；But in daily life, user is often being closed Forget to cause rotatable handle to cold water control area that can directly initiate heat when upper lift handle Open valve next time after hot water Hydrophone will result in the waste of hot water if not needing hot water at this time.
Meanwhile at present by valve controlling flow body, especially control hot fluid, the fluid for providing fluid for valve is supplied Device is answered, the hot fluid feeding mechanism of hot fluid is especially supplied, since 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, can not be by each With the fluid supply temperature of valve control 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.For example, it is that some temperature A is usually proper that toilet, which is washed one's hands,； And kitchen is washed the dishes, and may be temperature D proper, it is that temperature E is proper that bathroom, which is had a bath again,.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 adjust cold water, hot water mixing ratio to control leaving water temperature roughly.
China's scarcity of fresh water resources, with water resource worsening shortages, kitchen, toilet etc. save water problem with water spot and are cured Add protrusion, there is an urgent need to water-saving results more preferably, use more convenient, flexible spool.
Summary of the invention
It is an object of the present invention to: a kind of valving is provided, is conducive to save the fluid that valving passes through；Together When, which can be that fluid supply apparatus, especially hot fluid feeding mechanism provide feedback information, be conducive to pass through valve Door realizes the control to fluid supply apparatus, the especially control to the hot fluid supply temperature of hot fluid feeding mechanism；And work as When being used cooperatively with hot fluid feeding mechanism, the normal use of the hot fluid feeding mechanism can be conducive to.
The second object of the present invention is: providing a kind of hot fluid supply system, is conducive to the hot fluid supply system The normal use of hot fluid feeding mechanism.
The third object of the present invention is: providing a kind of fluid feed system using this patent valving.
The fourth object of the present invention is: providing a kind of single handle duplex water-saving spool, is conducive to save water, and is conducive to heat Hydrophone normal use.
The object of the invention is realized by following technical proposals:
A kind of valving, including fluid by when control valve gear of the fluid by state, and by its behaviour Make to carry out the operating mechanism that aforementioned 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 for adjusting first fluid and second fluid mixability Adjustment region, and the flow regulation zone of its fluid outlet flow, mixability tune are adjusted in mixability adjustment region Section region includes that the fluid outlet that must have only goes out the first fluid region of first fluid and fluid outlet only goes out second fluid Second fluid region, and the fluid outlet that can have brings out the mixing region of first fluid and second fluid fluid-mixing, behaviour Make mechanism and is greater than zero, and the stream in second fluid region in the flow of the minimum stop bit of the flow regulation zone in first fluid region The flow for measuring the minimum stop bit of adjustment region is equal to zero.
In the present invention program, the first fluid, second fluid can be the fluid of identical type, be also possible to not of the same race The fluid of class, such as respectively water and other fluids, or be all water, etc.；It meanwhile can be the one species of different conditions Fluid, is also possible to the one species fluid of same state, such as respectively hot water or cold water, is perhaps all cold water or is all Hot water.It is described hot and cold, only between the two in contrast, absolute sense is not had, hot water is only opposite cold water temperature Spend higher water.Cold water typically refers to normal-temperature water, and most common is exactly the tap water of daily life, meanwhile, cold water is also possible to The lower water of the temperature that normal-temperature water is further cooled down.And hot water, then it is commonly referred to as further heating normal-temperature water and mentions 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 hot water or cold water, and hot water becomes second fluid relatively, in turn Can be using hot water as first fluid, and cold water is naturally opposite as second fluid.In the mixability adjustment region, mixing Region is that optionally, i.e., fluid outlet can only go out first fluid or second fluid, and cannot go out fluid-mixing；And mix journey In degree, when first fluid accounting 100% when 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% when second fluid accounting 100%, i.e., fluid outlet only goes out second fluid Second fluid region.The flow regulation zone refer to operating mechanism adjust flow can operating physical section, 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 refer to control handle adjust flow can operating physical position； (single handle dual valve is typically) for the tap of formula opening ways is opened in lift, lift is opened formula handle and is opened by upper lift vertically, Water flow is controlled with the angular dimension lifted, when angle is zero, tap is closed, and handle position is lower position-arresting at this time, is Minimal adjustment position (minimum stop bit/minimum stop position)；And when lifting angle maximum (usual maximum flow at this time), hand at this time 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 controls water flow with the angular dimension of unlatching, and opening angle is bigger, and flow is bigger, and angle is this of 0 ° A point (usually closed position) be minimal adjustment position (minimum stop bit/minimum stop position), and angle it is maximum another Point (usually maximum stream flow position) is maximal regulated position (maximum stop bit/maximum stop position).
The present invention program, relatively existing various valves, especially relatively existing common single handle duplex spool, flow Adjustment region is in addition to having the null closed position of flow of the shared minimum stop bit of the prior art, and the position of big regulated value Except, 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 the 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 greater than zero by this patent It sets.For example by the flow design of this minimum stop bit be the flow A for being suitble to wash one's hands, operating mechanism is easily and rapidly placed in the position It sets and the flow for being suitble to wash one's hands can be obtained.By taking common single handle duplex spool as an example, the handle of existing list handle duplex spool is most left Side most descend operating position (usually first fluid region, such as the closed position of hot water) and rightmost most descend operating position (usually second fluid region, such as the closed position of cold water) is all closed position, and this patent handle is placed in it is leftmost Most descend operating position to can be obtained the particular flow rate A for being suitble to wash one's hands, and by handle be placed in rightmost most descend operating position then and Existing list handle duplex spool is equally in off state；Vice versa, handle can also be placed in rightmost most by this patent Lower operating position can be obtained the particular flow rate A for being suitble to wash one's hands, and handle is placed in and leftmost most descends operating position then and existing There is single handle duplex spool to be equally in off state.
Based on previous designs, by taking daily water consumption as an example, the present invention can use water spot/use occasion, design tool according to different There is the minimum stop bit of the difference of flow regulation zone of the operating mechanism in first fluid region, for example forms flow respectively and correspond to and be suitble to Flow A that toilet is washed one's hands, it is suitble to kitchen to wash the series of the flow B of vegetables and fruits, the flow C for being suitble to living balcony laundry clothes, etc. The valve of model is respectively applied to each personal water spot/use occasion, realizes use most humanized and convenient while maximizing It is water-saving.
Further, since valve of the invention is in addition to also having one with closed state and maximum stream flow state The particular state of particular flow rate, then the particular state of this particular flow rate can become identification signal/control of the valve Signal, fluid supply apparatus can identify the valve according to the particular flow rate information, so that corresponding take corresponding control operation. By taking hot fluid feeding mechanism (such as water heater) carries out water temperature control as an example, user, first will operation when toilet is washed one's hands Mechanism passes directly to the particular state, starts water heater, water heater can detect (induction) arrive it is specific with the valve of the toilet The corresponding signal specific of flow A (such as flow value or dynamic pressure/static pressure ratio or dynamic pressure/full pressure ratio or static pressure/dynamic pressure ratio Deng), the valve for being identified as toilet is carrying out handwash operation, and leaving water temperature is directly adjusted to the prefabricated suitable temperature washed one's hands A；And operating mechanism is equally passed directly to the particular state first when kitchen is washed the dishes by user, starts water heater, water heater The signal specific for receiving the particular flow rate D of the valve in the kitchen, the valve for being identified as kitchen are carrying out dishwashing operations, will directly go out Coolant-temperature gage is adjusted to the prefabricated suitable temperature D to wash 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 the prior art has one and closes its heating system Minimum flow, the water heater will close heating system (flame-out) when being lower than the minimum flow, and operating mechanism of the invention can be with It is greater 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, subsequent cold water also can and then enter water tank, cold But water tank had not only realized making full use of for hot water as a result, but also solved water tank fouling and continue to use hot water, part hot water temperature The significant higher problem of degree.
Alternatively, flow of the operating mechanism in the maximum stop bit of the flow regulation zone in first fluid region, He 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 is lived, in production Common faucet valve core, especially potsherd quick-opened valve core have been the faucet valve cores being commonly used.Potsherd is opened fastly Spool has many advantages, such as that control handle operation is smooth lightly, potsherd (fixinig plate, movable plate) is sealed and the spool service life is long.It is another Aspect, since control handle is smooth light and handy, when unlatching, is easy water flow opening to the maximum value, formed mass-flow and causes to waste；Together When, since control handle flow adjusting stroke is shorter, it is unfavorable for more accurately controlling water flow.That is, in daily life, although water Faucet can obtain maximum stream flow when control handle is opened into maximum, but under most service conditions, will not all use most Big flow, even if big flow is needed to use, generally also one when young in one big flow of maximum stream flow.And the existing fire hose Control handle all promptly can not be adjusted to the position by head, 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 meeting different fluid use demand, can be most Fluid is saved to limits, different maximum stream flows can be further selected according to the difference of use demand.

The foregoing main solution of the present invention and further alternatives thereof can be freely combined to form multiple schemes, be this Invention can be used and claimed scheme: such as the present invention, each non conflicting select (such as select 3,4,5 and A, B, C be to conflict Selection, cannot combine between each other, and can only with other main schemes or selection combine) selection between or between main scheme arbitrarily Combination, etc., there are many those skilled in the art can be illustrated after understanding the present invention program according to the prior art and common knowledge Combination is the claimed technical solution of the present invention, does not do exhaustion herein.
Beneficial effects of the present invention: valving is conducive to save the fluid that valving passes through；Meanwhile the valve fills Setting to be fluid supply apparatus, and especially hot fluid feeding mechanism provides feedback information, is conducive to realize convection current by valve The control of body feeding mechanism, the especially control to the hot fluid supply temperature of hot fluid feeding mechanism；And it is supplied when with hot fluid When device being answered to be used cooperatively, the normal use of the hot fluid feeding mechanism can be conducive to.Specifically:
(1) spool critical state is set, big flow and small flow are separated.By setting critical state and by water-saving spool stream Amount adjustment region is divided into big flow adjustment region (being greater than critical state flow) and (is less than critical state with small flow regulation zone Flow), the flow regulation zone or critical state for facilitating water user's selection suitable are conducive to save water.
(2) convenient and fast operating method, control handle is placed in the operation of critical state (saving state) by water-saving spool, similar general For port valve core by the operation of control handle merging closed state, operating method is simple, quick.Increase control handle and adjust stroke, is conducive to Adjust flow.The one-part form of common spool control handle is adjusted into the two-period form that stroke spread is water-saving spool and adjusts stroke, due to Adjusting stroke spread adjusts control handle flow more accurately, conveniently.
(3) common spool operating method is taken into account, and retains common spool advantage.Water-saving spool is using similar with common spool Unlatching, shutoff operation method, and the advantages of remain common spool, for example, hot and cold water is easy to adjust flexibly, control handle operation The advantages that smooth light and handy and spool service life is long.Compared with the present invention: having a kind of valve that segmentation gear is set using elastic element Core, when manipulating this multi gear position spool, conversion between gear can be carried out by needing to suppress gear elastic force, both lose control The smooth light and handy operating handle of handle, and shorten spool service life.
(4) water-saving and energy saving.Water-saving spool is used and (there is single heat pattern critical state), is not only conducive to save water, And hot water open frequency and energy saving can be reduced.The reason is as follows that: due to single heat pattern lower position-arresting of above-mentioned water-saving spool For critical state, guide water user that control handle is placed in other mode lower position-arrestings (for example, single cold mode when closing water-saving spool Lower position-arresting), using can avoid for control handle being placed in single heat pattern adjustment region as far as possible when cold water, to reduce unlatching hot water Frequency simultaneously reduces energy waste.
(5) it is conducive to water heater normal use.For using gas heater as the cold and hot water supply system of heat source, using having single heat The water-saving spool of mode critical state, and the flow value of water-saving spool list heat pattern critical state is set smaller than gas and hot water The minimum closing flow value of device can not only save hot water and also be especially beneficial gas heater normal use.Its mode of operation are as follows: (a) during using hot water, if not needing big flow hot water, control handle can be placed in small flow regulation zone (or critical shape State).On the one hand, since small flow regulation zone is less than critical state flow, that is, it is less than the minimum closing flow of gas heater, combustion Gas water heater extinguishing does not consume combustion gas；On the other hand, cold since water-saving spool is in small flow regulation zone (or critical state) Hot-water heating system (in hot water line and gas heater internal reservoir) still has small flow hot water outflow that can meet short time hot water need It asks.(b) when closing hot water, control handle is placed in by (single heat pattern or cold and hot mixed mode) big flow adjustment region in advance Big flow hot water is switched to small flow hot water by (single heat pattern) small flow regulation zone or critical state, finally will control Handle is placed in closed state by small flow regulation zone (or critical state).Aforesaid operations can not only save hot water, combustion gas, may be used also To effectively prevent gas heater encrustation, (spool saves state lower water-heater and stops working, and internal hot-water is continued to flow out for making With, while cold water enters water heater and reduces water heater temperature), conducive to keeping the normal heat transfer efficiency of water heater and extending using the longevity Life.
