Description

The valving and its fluid feed system of bilateral 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 is divided into fluid outlet, and only the first fluid region of first fluid and fluid outlet only go out the second of second fluid out 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 outlet the mixing region of first fluid and second fluid fluid-mixing, operating mechanism is the One, the flow of the minimum stop bit of the flow regulation zone of two fluid masses is all larger than zero, and in the flow regulatory region 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, 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, 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 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).There are two types of shapes for intermediate region State, one is the fluid outlets of the intermediate region not to go out fluid, and another kind is that fluid outlet brings out first fluid and second The state of body fluid-mixing is defined as mixing region.

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 (firm discharge of two fixed positions of two extreme positions of firm discharge between the two Can be identical, can also 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 the first and second fluid mass is then changed to flow greater than zero by this patent Particular flow rate control position.When the firm discharge difference of the fixed position of both of the aforesaid, such as by the two minimum stop bits Flow separately design to be suitble to the flow A to wash one's hands and be suitble to wash the flow B of vegetables and fruits, operating mechanism is easily and rapidly placed in pair Answer position that the flow that is suitble to wash one's hands or wash vegetables and fruits can be obtained.By taking common single handle duplex spool as an example, existing list handle dual valve The handle of core is leftmost most to descend operating position (usually first fluid region, such as the closed position of hot water) and rightmost is most Lower operating position (usually second fluid region, such as the closed position of cold water) is all closed position, and this patent sets handle It most descends operating position to can be obtained the particular flow rate A for being suitble to wash one's hands in leftmost, and most descends behaviour for what handle was placed in rightmost It can be obtained the particular flow rate B for being suitble to wash 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 mixes) then it is in off state as existing single handle duplex spool；In turn Similarly, what handle can also be placed in rightmost by this patent most descends operating position that the particular flow rate for being suitble to wash fruits and vegetables can be obtained B, and handle is placed in the leftmost particular flow rate A for most descending operating position then to obtain being suitble to wash one's hands, and intermediate most descend operation Position is then in off state as existing single handle duplex spool.

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 to correspond to flow, for example forms flow respectively Flow A, the flow C for being suitble to kitchen to wash the flow B of vegetables and fruits, be suitble to living balcony laundry clothes 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 use it is most humanized and convenient same When maximize it is water-saving.In particular, the valve of this patent has there are two particular flow rate simultaneously, can respectively correspond two kinds with water spot/ Use occasion.

Further, since valve of the invention is in addition to closed state and maximum stream flow state, also there are two tool 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 taken if needing to do washing in toilet, the corresponding laundry clothes of the particular flow rate of another particular state of the valve are suitble to temperature Temperature is adjusted to be suitble to the temperature of laundry clothes by the feedback signal of degree, water heater again；And user is when kitchen is washed the dishes, equally Operating mechanism is passed directly into the particular state first, starts water heater, water heater can detect (induction) to the valve with the kitchen The corresponding signal specific of particular flow rate D of door, the valve for being identified as kitchen is carrying out dishwashing operations, directly by leaving water temperature tune It saves to the prefabricated suitable temperature D to wash the dishes；Kitchen valve can equally have the particular state of two particular flow rates, feed back respectively Make the suitable water temperature of its output setting to water heater.Likewise, it is also such that bathroom, which is had a bath,.Similarly, valving can also be with Only one of them inlet opening connects hot water, i.e., merely with the particular state of the one of particular flow rate of spool as identification/control Signal.

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.Meanwhile this patent valve has the minimum stop bit of the flow regulation zone of the first and second fluid mass Flow is all larger than zero, and therefore, the first and second fluid inlet end can connect two hot fluid feeding mechanisms respectively, for example connect combustion respectively Gas water heater and electric heater can be used when only stopping the supple of gas or steam or only powering off；Such as connect respectively quick immediately heating water heater and Large capacity displacement type water heater meets quickly obtain hot water and largely using hot water different demands, etc. respectively.

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.
