Description

Single handle duplex water saving spool and fluid feed system thereof

Technical field

This utility model belongs to valve field, particularly relates to spool technical field used by faucet, particularly to one list Handle duplex water saving spool.

Background technology

Valve, as one of control equipment the most frequently used in productive life, is used for controlling fluid and passes through state, such as control The fluid type that passes through, control the fluid flow that passes through.Ordinary people understands, contacts most is exactly water used in daily life Tap.Faucet is commonly divided into spirally by opening ways, Wrench-type, lift the formula of opening and vicarious etc..Spiral handle passes through Screwing and open, and when opening, will rotate a lot of circle, by the number of turns adjusting water outlet flow screwed, it is the most to screw the number of turns, flow The biggest；Wrench-type handle is opened by horizontal rotation, controls water flow with the angular dimension opened, and opening angle is the biggest, Flow is the biggest, and maximum angle is typically 90 °；Lift and open formula handle and open by lifting on vertically, equally, come with the angular dimension opened Controlling water flow, opening angle is the biggest, and flow is the biggest, and maximum angle is typically smaller than 45 °；As long as inductive water tap handle is stretched Under faucet, by sensing automatic outletting, but generally water flow is fixing, it is impossible to regulation.

Single handle duplex spool is modal faucet valve core, especially potsherd list handle duplex spool in life, production, It has been the valve core for cold/hot water faucet commonly used in current kitchen, toilet.Spool includes the sealing that stator and moving plate are constituted Sheet, operating mechanism is to control moving plate opposing stator to seal the control handle slided, and stator is provided with cold inlet opening, hot inlet opening And apopore, moving plate is provided with passage, and this passage in order to connect hot inlet opening and to go out when moving plate opposing stator seals and slides Water hole, or cold inlet opening and apopore, or hot inlet opening, cold inlet opening and apopore.To lift single handle dual valve of the formula of opening As a example by core, the domestic usual operation standard of China is, it is that apopore only goes out hot water that control handle turns left to extreme position near zone, Now apopore only passes through channel connection with hot inlet opening；Control handle is turned right, and to be that apopore only goes out to extreme position near zone cold Water, now apopore only passes through channel connection with cold inlet opening；It is the most then the mixed aqua region of hot and cold water mixing, this Time apopore simultaneously with hot and cold inlet opening by channel connection, control handle more toward left-handed, hot water ratio in hot and cold water inlet ratio The biggest, water is the warmmest, until becoming purely hot water；Control handle is more toward dextrorotation, and in hot and cold water inlet ratio, cold water ratio is the biggest, and water is more Cold, until becoming purely cold water.And in control handle left rotation and right rotation, by above lift control handle on lift angular adjustment going out this moment Discharge, the biggest flow of angle is the biggest.

Potsherd list handle duplex spool has that hot and cold water is easy to adjust flexibly, smooth light and handy, the potsherd of control handle operation (Gu Stator, moving plate) advantage such as good seal and spool life-span length.

But, no matter how the control mode of existing various valves changes, particularly various used in daily life Faucet, it only has two firm discharge adjusting positions, closes the closed position of water and the accommodation limit position that water flow is maximum Putting, only in the two position, operating mechanism regulation can the most promptly be put in place by user, and corresponding Flow-rate adjustment is to fixing Size is (for modal single handle duplex spool, it is simply that lift the maximum to upper limit (UL) point on closed position, and handle Flow position).And user to obtain when closing to arbitrary flow between maximum stream flow, then need slowly carefully to regulate behaviour Make mechanism and could realize (for modal single handle duplex spool, it is necessary to up-down adjustment handle angle repeatedly).But it is real In the life of border, a certain flow that the flow that user needs is closed the most exactly between maximum stream flow, spend relatively at user For a long time by operating mechanism regulation to necessary flow time, causing the waste of many water resources the most already.

Meanwhile, in routine use, different uses water spot/use occasion, is different for suitable water flow: ratio As, washing one's hands in toilet is that certain flow A is the most proper, can meet the demand of cleaning, does not results in again the mistake of water simultaneously Many wastes；Vegetables and fruits are washed in kitchen, and to be then probably flow B proper, and living balcony laundry clothes are again that flow C is proper.And lead to Chang Eryan, between flow A, B, C and differ, user is under various difference water spot/use occasions, it is impossible to quickly and accurately Operating mechanism regulation is put in place, it is achieved required flow-control.

Additionally, for by Valve controlling thermal fluid flow, common for controlling hot water flow time, correspondence has one and carries 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 connects, and hot fluid feeding mechanism common in daily life is various water heater, such as gas heater, electric hot water Device etc..Between hot fluid feeding mechanism (such as water heater) to valve, there is one section of pipeline, when hot water uses complete, close valve closing After Men, the hot water retained in this section of pipeline and in water-heater water tank cannot be obtained by, 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, reduces water heater service life and the efficiency of heating surface.This Outward, during using hot water, suspend in the case of using hot water, after closing valve, still absorb due to water tank and have the highest heat Amount, now this high heat will still continue to the hot water retained in water tank is continued heating, and now the water in water tank can be heated to Significantly exceed original control temperature, now open valve when being continuing with hot water, when retaining hot water from valve in this part water tank When door is released, user can substantially find that this part coolant-temperature gage is the most too high, affect experience, even cause boiling hot time serious Wound.And, for common single handle duplex spool, hot water control area is in left side, and cold water control area is on right side, heat After water uses, user presses down handle can close hot water on earth；But in daily life, user is often being closed Forgotten rotatable handle after hot water to cold water control area, cause raising one's hand on next time handle Open valve time can directly initiate heat Hydrophone, if being now not required to hot water, will result in the waste of hot water.

Meanwhile, at present by Valve controlling fluid, particularly control hot fluid, for providing the fluid of fluid to supply for valve Answer device, particularly supply the hot fluid feeding mechanism of hot fluid, owing to hot fluid (such as hot water) temperature can only be at 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 Fluid supply temperature with 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, wash one's hands in toilet is that certain temperature A is the most proper； Washing the dishes in kitchen, is probably temperature D proper, has a bath and be that temperature E is proper in bathroom.Under the prior art, user Hot fluid supply temperature can only be repeatedly regulated continually at hot fluid feeding mechanism (such as water heater), or logical on valve Cross and substantially regulate cold water, hot water mixing ratio controls roughly leaving water temperature.

China's scarcity of fresh water resources, along with water resource worsening shortages, the water spot using water wisely problem such as kitchen, toilet heals Add prominent, in the urgent need to water-saving result more preferably, use more convenient, spool flexibly.

One of the purpose of this utility model is: provide a kind of valving, is conducive to saving the stream that valving passes through Body；Meanwhile, this valving can be fluid supply apparatus, and particularly hot fluid feeding mechanism provides feedback information, is conducive to The control of convection cell feeding mechanism is realized, particularly the control to the hot fluid supply temperature of hot fluid feeding mechanism by valve System；And when with hot fluid feeding mechanism with the use of time, the normal use of this hot fluid feeding mechanism can be conducive to.

The two of the purpose of this utility model are: provide a kind of hot fluid supply system, are conducive to this hot fluid supply system The normal use of the hot fluid feeding mechanism of system.

The three of the purpose of this utility model are: provide a kind of fluid feed system using this patent valving.

The four of the purpose of this utility model are: provide a kind of single handle duplex water saving spool, beneficially using water wisely, and profit Normally use in water heater.

This utility model purpose is realized by following technical proposals:

A kind of valving, is included in the control fluid valve gear by state when fluid passes through, and by grasping at it Carrying out operating the operating mechanism realizing aforementioned control in making region, valve gear has first fluid arrival end, second fluid entrance End and fluid outlet, the operating area of operating mechanism is divided into regulation first fluid and the mixability of second fluid mixability Regulation region, and the flow regulation zone of its fluid outlet flow is regulated in mixability regulation region, mixability is adjusted Joint region is divided into fluid outlet only to go out the first fluid region of first fluid, and fluid outlet only goes out the second of second fluid Zone line between fluid mass, and first fluid region and second fluid region, the fluid outlet of this zone line Not going out fluid, or bring out the mixing region of first fluid and second fluid fluid-mixing for fluid issuing, operating mechanism is One, 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 district in mixing region The flow of the minimum stop bit in territory is equal to zero.

In this utility model scheme, described first fluid, second fluid can be the fluid of identical type, it is also possible to be not Congener fluid, the most respectively water and other fluids, or be all water, etc.；Meanwhile, can be the same of different conditions Categories of fluid, it is also possible to be the one species fluid of same state, the most respectively cold water and hot water, or be all cold water, or It is all hot water.Described hot and cold, it is only the most comparatively speaking, does not has absolute sense, hot water is the most relatively cool The higher water of coolant-temperature gage.Cold water typically refers to normal-temperature water, and modal is exactly the tap water of daily life, and meanwhile, cold water also may be used To be the lower water of the temperature obtained of normal-temperature water being lowered the temperature further.And hot water, then it is commonly referred to as normal-temperature water is added further Heat improves the water of temperature.Additionally, first fluid, second fluid are used only for difference definition two-way fluid, it is not absolute definition, Such as, for cold water and hot water, can be using cold water as first fluid, and hot water becomes second fluid relatively, in turn Can also be using hot water as first fluid, and cold water becomes second fluid the most relatively.In described mixability regulation region, mixed It is optional for closing region, i.e. fluid outlet can only go out first fluid or second fluid, and can not go out fluid-mixing；And mix In degree, when first fluid accounting 100% during second fluid accounting 0%, i.e. fluid outlet only goes out the first of first fluid Fluid mass；In turn, when first fluid accounting 0% during second fluid accounting 100%, i.e. fluid outlet only goes out second The second fluid region of body.Described flow regulation zone refers to that the operable physics of operating mechanism regulation flow is interval, includingMust HaveMinimal adjustment position (minimum stop bit/minimum stop position), regulate region,AndCan haveMaximal regulated position is (maximum Stop bit/maximum stop position)；Similarly, described control handle implantation site refers to the operable physical bit of control handle regulation flow Put；For lifting the faucet opening formula opening ways (be typically single handle dual valve), lift and open formula handle and beat by lifting on vertically Opening, control water flow with the angular dimension lifted, when angle is zero, faucet is closed, and now handle position is lower position-arresting, For minimal adjustment position (minimum stop bit/minimum stop position)；And when lifting angle maximum (now usual maximum flow), now Handle position is upper position-arresting, for maximal regulated position (maximum stop bit/maximum stop position).Similarly, Wrench-type handle passes through Horizontal rotation is opened, and controls water flow with the angular dimension opened, and opening angle is the biggest, and flow is the biggest, and angle is 0 ° This point (usually closed position) is minimal adjustment position (minimum stop bit/minimum stop position), and another of angle maximum Individual point (usually maximum stream flow position) is maximal regulated position (maximum stop bit/maximum stop position).Zone line has two kinds State, a kind of is that the fluid outlet of this zone line does not go out fluid, another kind of brings out first fluid and second for fluid issuing The state of fluid fluid-mixing, is defined as mixing region.

This utility model scheme, the most existing various valves, the most existing common single handle duplex spool, its Flow regulation zone is except possessing the null closed position of flow of the total minimum stop bit of prior art, and big regulated value Outside position, it is also equipped with minimum stop bit (two fixed positions fixing of two extreme positions of firm discharge between the two Flow can be identical, it is possible to different, preferably different).It is with the difference of existing valve, and existing valvular operating mechanism is the One, 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 position is equal For closed position, it is big that this patent then changes the minimum stop bit of the flow regulation zone of wherein first and second fluid mass into flow The control position of the particular flow rate in zero.When the firm discharge difference of both of the aforesaid fixed position, such as that the two is minimum The flow of stop bit separately designs as being suitable for the flow A washed one's hands and the flow B being suitable for washing vegetables and fruits, is easily and rapidly put by operating mechanism The flow being suitable for washing one's hands or wash vegetables and fruits i.e. can be obtained in correspondence position.As a example by common single handle duplex spool, existing single handle is double The handle of connection spool is leftmost most descends operating position (usually first fluid region, such as the closed position of hot water) and rightmost Most to descend operating position (usually second fluid region, such as the closed position of cold water) be all closed position, and this patent is by hands Handle is placed in and leftmost descends most operating position i.e. can obtain particular flow rate A being suitable for washing one's hands, and handle is placed in rightmost Lower operating position i.e. can obtain being suitable for washing particular flow rate B of vegetables and fruits, and region between most descend operating position (generally For Mixed Zone, such as the closed position of mixed water of hot and cold water mixing) then the same with existing single handle duplex spool be closed mode；Instead Coming over too, handle can also be placed in and rightmost most descend operating position i.e. can obtain being suitable for washing the specific of fruit and vegerable by this patent Flow B, is placed in handle and leftmost descends most operating position then to obtain particular flow rate A being suitable for washing one's hands, and centre under Operating position is then the same with existing single handle duplex spool is closed mode.

Based on previous designs, as a example by daily water consumption, this utility model can according to difference water spot/use occasion, if Meter has the different minimum stop bit correspondence flow of the operating mechanism flow regulation zone in first fluid region, is such as formed respectively Flow correspondence is suitable for the flow A washed one's hands toilet, the flow B of vegetables and fruits is washed in applicable kitchen, be suitable for the flow of living balcony laundry clothes C, etc. the valve of serial model No., be respectively applied to each personal water spot/use occasion, it is achieved hommization and the facility of use Change and maximize water saving simultaneously.Particularly, the valve of this patent has two particular flow rate simultaneously, can distinguish correspondence two kinds water Point/use occasion.

Further, owing to valve of the present utility model is except having closed mode and maximum stream flow state, also have The particular state of two particular flow rate, then the particular state of this particular flow rate just can become the identification signal of this valve/ Control signal, fluid supply apparatus can be according to this particular flow rate this valve of information identification, thus correspondence is taked to control accordingly Operation.As a example by hot fluid feeding mechanism (such as water heater) carries out water temperature control, user, when washing one's hands in toilet, first will Operating mechanism passes directly to this particular state, starts water heater, and water heater can detect (sensing) and arrive valve with this toilet The corresponding signal specific of particular flow rate A (such as flow value or dynamic pressure/static pressure ratio or dynamic pressure/full pressure ratio or static pressure/dynamic Pressure ratio etc.), the valve being identified as toilet is carrying out handwash operation, directly leaving water temperature regulation applicable is washed one's hands to the most prefabricated Temperature A；And if need at toilet laundry clothes, then the particular flow rate correspondence laundry clothes of another particular state of this valve are suitable Closing the feedback signal of temperature, temperature is adjusted to be suitable for the temperature of laundry clothes by water heater again；And user is when washing the dishes in kitchen, First operating mechanism passing directly to this particular state, starts water heater, water heater can detect (sensing) and arrive and this kitchen The corresponding signal specific of particular flow rate D of valve, the valve being identified as kitchen is carrying out dishwashing operations, directly will go out water temperature Degree regulation is to prefabricated applicable temperature D washed the dishes；Kitchen valve equally possesses the particular state of two particular flow rate, respectively Feeding back to water heater makes it export the suitable water temperature of setting.Same, it is also such for having a bath in bathroom.Similarly, valving is also Can with only one inlet opening connect hot water, i.e. merely with one of them particular flow rate of spool particular state as identify/ Control signal.

Meanwhile, the hot fluid feeding mechanism (such as gas heater) of prior art has its heating system of closedown Minimum flow, less than this water heater during this minimum flow by closedown heating system (stopping working), and operating mechanism of the present utility model Can be at the flow of the minimum stop bit of the flow regulation zone in first fluid region (hot water region) more than zero, when this is minimum only During the minimum flow that the flow of position is closed less than water heater, in water heater, heating system will be closed, and valve is between water heater Retaining hot water and still can discharge from valve in pipeline and water-heater water tank, follow-up cold water also can and then enter water Case, cooling water tank, thus, both achieved making full use of of hot water, and solved again water tank fouling and be continuing with hot water, part heat The problem that coolant-temperature gage is the most higher.Meanwhile, the minimum of the flow regulation zone that this patent valve possesses first and second fluid mass is stopped The flow of position is all higher than zero, and therefore, first and second fluid inlet end can connect two hot fluid feeding mechanisms respectively, such as distinguishes Connect gas heater and electric heater, only stopping the supple of gas or steam or can use during only power-off；Connect quick Instant heating type hot water the most respectively Device and Large Copacity displacement type water heater, meet respectively and quickly obtain hot water and a large amount of use different demands of hot water, etc..
