For general liquid delivery system or equipment (comprise there is the liquid-storage device storing processed good liquid system or equipment as common solar water heater, boiler and not there is the liquid-storage device storing processed good liquid system or equipment as common Instant heating type gas water-heater), this recycle device can be loaded in the pipeline of the liquid outlet end of liquid delivery system or equipment, now the inlet pipe of this device communicates with the liquid outlet of liquid delivery system or equipment, namely the pipeline of the liquid approach axis of inlet pipe and described liquid delivery system or equipment is connected, the pipe that goes out of this device communicates with the user side pipeline of liquid delivery system or equipment, namely go out pipe to be connected with the pipeline of the liquid stream outgoing direction of described liquid delivery system or equipment.After the related valve opening liquid delivery system or equipment, the sensor of perception liquid situation records liquid and starts flowing, and recycle device enters working state; Meet the requirements if the sensor of now perception liquid properties records ducted liquid, then this recycle device keeps normal state, namely inlet pipe with go out pipe and communicate, extract that pipe is closed, liquor pump does not start out, liquid delivery system or the satisfactory liquid of equipment regular supply; If the signal that the sensor of perception liquid properties records and the acceptance value set in advance compare rear when determining that the performance of liquid is undesirable, namely reclaim undesirable liquid in advance by control circui mortor operated valve and liquor pump, then supply satisfactory liquid.Now first can reclaim undesirable liquid in this recycle device to the pipeline of liquid delivery system or device interior, reclaim undesirable liquid in this recycle device to the pipeline of user side again, an advantage of this mode is that liquid delivery system or equipment can continuous firing a period of times, can not once startup stopping again.Preferably: make going out pipe and extracting that pipe communicates, inlet pipe is closed, liquor pump starts out of recycle device by controlling the mortor operated valve of three-port structure, recycle device is extracted out for re-using to the ducted liquid of user side, and record after ducted liquid is evacuated at the sensor of perception liquid situation, make its inlet pipe by controlling the mortor operated valve of recycle device and extract pipe out and communicate, go out that pipe is closed, liquor pump works on, liquid undesirable in recycle device to liquid delivery system or device interior pipeline is extracted out and supplies re-using; Now liquid delivery system or equipment start to flow out treated liquid, when the sensor of perception liquid properties record ducted liquid meet the requirements time, control circuit can make the inlet pipe of recycle device and go out pipe and communicate, extract that pipe is closed, liquor pump stops out, and liquid delivery system or equipment can the satisfactory liquid of regular supply.When closing the valve of the liquid feeding end of user side valve or liquid delivery system or equipment or outlet end, the sensor of perception liquid situation makes this recycle device deactivate state because recording liquid and stopping flowing, each electric valve and liquor pump return to normal.If this recycle device is loaded near user side valve, then once can extracts user side out and retain liquid to liquid delivery system or the ducted of device interior.
For there is no liquid-storage device but the liquid delivery system at once processed ducted liquid or equipment (as domestic gas-fired water heater or instant electric water heater), this recycle device can also be loaded in the liquid entering hole pipeline of liquid delivery system or equipment, now the inlet pipe of this device communicates with the stoste liquid inlet pipe of liquid delivery system or equipment, goes out pipe and communicates with the liquid entering hole of liquid delivery system or equipment.Such as gas water-heater that is Instant heating type or Quick-action type, this device can be loaded in the cooling water inlet pipeline of gas water-heater, now the inlet pipe of this device is connected with the cold water inlet of gas water-heater, go out pipe to be connected with the cooling water inlet of gas water-heater, and the hot water outlet of described water heater is directly connected with the pipeline leading to user side.After the related valve opening water heater, the sensor of perception liquid situation records liquid and starts flowing, and recycle device enters working state; If the ducted liquid that the sensor of now perception liquid properties records the outlet end of liquid delivery system or equipment meets the requirements, this recycle device keeps normal working, namely inlet pipe with go out pipe and communicate, extract that pipe is closed, liquor pump does not start out, liquid delivery system or the satisfactory liquid of equipment regular supply; When the performance that the sensor of perception liquid properties records liquid is undesirable, the signal of the sensor mortor operated valve namely by controlling recycle device makes it go out pipe and extract that pipe communicates, inlet pipe is closed, starting mode of pump out, to be extracted out by gas water-heater supply re-using to the ducted resident water of user side together with the resident water of gas water-heater inside; When the sensor of perception liquid situation records after resident water is evacuated, namely make it go out pipe by the mortor operated valve of control recycle device to communicate with inlet pipe, extract pipe closedown, water pump stopping out, gas water-heater can normally use, cold water by the inlet pipe of this recycle device, go out pipe and enter gas water-heater and heat, namely the water that gas water-heater outlet is released be hot water, then flowed out from user side by pipeline.When closing the valve of the liquid feeding end of user side valve or liquid delivery system or equipment or outlet end, the sensor of perception liquid situation makes this recycle device deactivate state because recording liquid and stopping flowing, each electric valve and liquor pump return to normal.Under this mounting type, the pipe that goes out of recycle device is operationally opening state always, and the Twoway valves therefore going out pipe direction can save (recycle device for adopting three-way pipe and Twoway valves).
Above-mentioned " sensor of perception liquid situation records liquid and starts flowing; recycle device enters working state ", also can be understood as only the sensor of perception liquid situation record liquid start to flow time, recycle device enters " work " state from " standby " state, and signal that the sensors such as perception liquid properties record is just by control circuit open and close mortor operated valve or startup, stop liquid pump; Not opening the valve of user side and supply system or equipment, liquid is when flowing, and recycle device can not work; It is the precondition that recycle device enters working state that liquid starts to flow.The false tripping of recycle device (such as the mistake start liquid pump when not using supply system or equipment) can be prevented like this.A kind of concrete implementation methods is: switch, flow of fluid switch or the water wave seesaw switch etc. that are controlled by the sensor of perception liquid flow condition are serially connected in the power circuit of recycle device, coming this by the flow signals of liquid, that recycle device is obtained is electric, thus enters working state.In fact, recycle device only just carries out the recycling of liquid when flow of fluid and liquid these two conditions undesirable are all set up, otherwise each mortor operated valve, liquor pump are in the normal state, and do not carry out the recycling of liquid.A kind of concrete implementation methods that therefore can also adopt is: the circuit switch that the circuit switch control the sensor of perception liquid properties and/or perception flow of fluid sensor control is serially connected in the power circuit of recycle device.
In addition, as long as also can by design on control circuit for liquid start flowing and liquid properties is undesirable, just can trigger recycle device to start working, the satisfactory fluid of regular supply after recovery fluid, and need not require that flow of fluid sensor records ducted liquid and is in flowing state always.But when abnormal operation (such as opening the valve of user side, recycle device close again the valve of user side when just starting working), the work of this recycle device likely can make mistakes at once.
The liquid reclaimed can be used for the washing of article or is separately used as him.For having the liquid delivery system of liquid storage vessel or equipment as solar water heater, electric water heater, boiler etc., also the liquid of recovery directly can be pressed in storage container and again utilize after process.
Further technological scheme is that described liquid transporting apparatus is communicated to liquid storage vessel such as fluid storage tank by delivery line.This fluid storage tank can be equipped with liquid and utilize outlet and valve, for storing the liquid of recovery.Like this, the utilization of withdrawal liquid is not necessarily carried out with the use of described recycle device simultaneously.
Further technological scheme is: described delivery line is communicated by the pipeline of the stoste entrance point of arm and described liquid delivery system or equipment, described arm is provided with arm mortor operated valve, described delivery line is provided with derivation mortor operated valve near one end of liquid storage vessel, described mortor operated valve is electrically connected with control circuit, is sent in the pipeline of the liquid-inlet of liquid delivery system or equipment during the liquid retained in extracted liquid supply system or equipment.For being arranged on the recycle device of liquid outlet end, when extracting recycle device out to the liquid of supply system or device interior, directly can be returned liquid delivery system or device interior recycles.Relative to following technological scheme, these component needed for rear technological scheme are less, less demanding to the working pressure of pump, also there is not problem when withdrawal liquid being returned stoste liquid inlet pipe, the quality, pressure etc. of liquid in liquid inlet pipe being caused to interference.
Utilize another technological scheme of withdrawal liquid to be the withdrawal liquid of described extraction is comprised the liquid be recovered in liquid storage vessel all to send in the stoste liquid inlet pipe of described liquid delivery system or equipment, make it meet the requirements after the process of liquid delivery system or equipment.For this reason, can the liquid of fluid storage tank be communicated in the pipeline of liquid-inlet end of described liquid delivery system or equipment by Circulation pipe and a liquor pump, also be provided with perception in described fluid storage tank and wherein have no liquid or the how many sensor of liquid, described sensor is electrically connected with control circuit, is controlled the switch of described liquor pump and relevant mortor operated valve by control circuit.Like this, when sensor perceive in fluid storage tank or Circulation pipe have liquid time, namely by control circuit start liquid pump, the withdrawal liquid in fluid storage tank is pressed in the liquid entering hole pipeline of described liquid delivery system or equipment; When sensor perceive in fluid storage tank or Circulation pipe there is no liquid time, i.e. closing liquid pump, stops the program of liquid entering hole pipeline withdrawal liquid being pressed into described liquid delivery system or equipment.Described Circulation pipe is preferably provided with valve, and opens when starting this liquor pump simultaneously.
The better technological scheme withdrawal liquid of described extraction sent in the stoste liquid inlet pipe of described liquid delivery system or equipment is connected on the extraction pipe of this recycle device by described fluid storage tank by Circulation pipe, manage the liquor pump that is connected and communicated by the liquid inlet pipe of the undressed stoste of delivery line and arm and described liquid delivery system or equipment with extracting out, at described Circulation pipe, on arm and described delivery line be respectively provided with mortor operated valve near one end of fluid storage tank, described mortor operated valve is electrically connected with control circuit, the element measuring its liquid situation is also provided with in described liquid storage vessel.A liquor pump can be share like this.
This recycle device can be arranged in the pipeline of the liquid outlet of liquid delivery system or equipment, and concrete control mode has following two kinds:
One, undesirable liquid in recycle device to liquid delivery system or device interior pipeline is directly pressed in liquid delivery system or equipment and recycles, namely to be evacuated to the ducted liquid of user side at recycle device and to have entered in fluid storage tank, control circuit makes the inlet pipe of recycle device communicate with extraction pipe, go out pipe to close, liquor pump works on and to extract out in recycle device to liquid delivery system or device interior pipeline when undesirable liquid, namely the mortor operated valve on arm is opened, close the mortor operated valve of delivery line near fluid storage tank one end, undesirable liquid in recycle device to liquid delivery system or device interior pipeline is directly pressed in described liquid delivery system or equipment and recycles, then the ducted liquid recording recycle device at sensor has met the requirements and has been made the inlet pipe of recycle device by control circuit and gone out pipe and communicate, extraction pipe is closed, when liquid delivery system or equipment start the satisfactory liquid of regular supply or afterwards, mortor operated valve in ON cycle pipe, and the mortor operated valve on arm is held open, the mortor operated valve of delivery line near fluid storage tank one end keeps cutting out, liquor pump keeps running, withdrawal liquid in fluid storage tank is pressed in described liquid delivery system or equipment, until the liquid situation sensor in mensuration fluid storage tank perceives in fluid storage tank when not had liquid, the valve on Circulation pipe and the valve on arm is closed again by control circuit, open the valve of delivery line near fluid storage tank one end, closing liquid pump, the program stopped of withdrawal liquid is pressed in liquid delivery system or equipment, this device returns to normal.
They are two years old, restarted program withdrawal liquid being pressed into described liquid delivery system or equipment liquid inlet pipe after the ducted liquid of user side and liquid delivery system or the ducted undesirable liquid of device interior have been pumped in fluid storage tank all with aforesaid way unlike, this mode.
Comparatively speaking, in the program of mode two, two steps that withdrawal liquid in the extraction of the undesirable liquid of liquid delivery system or device interior and fluid storage tank is pressed in described liquid delivery system or equipment liquid inlet pipe are more successively carried out, and fluid storage tank need hold the liquid reclaimed from user side pipeline and the liquid reclaimed from liquid delivery system or device interior pipeline; In mode one, extraction and two steps it be pressed into again in described liquid delivery system or equipment of the undesirable liquid of liquid delivery system or device interior are carried out simultaneously, fluid storage tank only need hold the liquid reclaimed from user side pipeline, and the volume of fluid storage tank can be less.
Above-mentioned the automatic recovery utilized device can manufacture separately and be arranged in the drain pipe pipeline of liquid delivery system or equipment easily, the connection part of the liquid outlet such as taking supply system or equipment apart and the pipeline leading to user side, recycle device is directly installed on centre, that is: by the inlet pipe of recycle device with go out pipe and be connected with the pipeline leading to user side with the liquid outlet of supply system or equipment respectively, take the stoste liquid entering hole of liquid delivery system or equipment and the connection part of input duct apart simultaneously, by the arm of recycle device by the liquid entering hole of a three-way pipe and liquid delivery system or equipment be with the liquid inlet pipe of liquid flowing valve and be connected respectively, and preferably in the liquid flowing valve direction of liquid delivery system or equipment, one one-way valve is installed.
When the above-mentioned the automatic recovery utilized device share liquor pump for there is no liquid-storage device but the liquid delivery system that ducted liquid is processed at once or equipment time, also can install by the mode in the aforementioned pipeline being arranged on the liquid entering hole of liquid delivery system or equipment.Its control mode is specifically: record at the sensor of perception liquid situation that liquid delivery system or device interior are ducted together with user side to retain after liquid is evacuated, made the inlet pipe of recycle device by control circuit and gone out pipe and communicate, extract pipe out and close, liquid delivery system or equipment start the satisfactory liquid of regular supply; Simultaneously, control circuit according to the signal of above-mentioned sensor or/and in fluid storage tank sensor unblanking arm on valve and valve in Circulation pipe, close the valve of delivery line near fluid storage tank one end, liquor pump starts, withdrawal liquid in fluid storage tank is pressed in described liquid delivery system or equipment, till sensor set in fluid storage tank perceives in fluid storage tank when not had liquid, at this moment, this recycle device returns to normal.
Above-mentioned the automatic recovery utilized device also can be installed easily, such as take the liquid entering hole of supply system or equipment and the connection part of input duct apart, recycle device is directly installed on centre, that is: the pipe that goes out of recycle device is connected with the liquid entering hole of liquid delivery system or equipment, the inlet pipe of recycle device is connected with the arm of recycle device with supply system or the input duct of equipment by a three-way pipe.
Not only preferred scheme uses two-way liquor pump can forward but also oppositely can carry the pump of liquid, the delivery line be connected with liquor pump is directly led to the bottom of fluid storage tank, cancel and the withdrawal liquid in fluid storage tank is pressed into Circulation pipe required in described liquid delivery system or equipment, arm and corresponding valve.Its control circuit had both controlled the flow direction by three-port structure, controlled again forward and reverse startup and the stopping of two-way liquor pump.This recycle device is arranged on does not have liquid-storage device but in the pipeline of the liquid entering hole of the liquid delivery system at once processed ducted liquid or equipment.When liquid delivery system or equipment liquid satisfactory by this recycle device regular supply, if when having the liquid reclaimed in fluid storage tank, this liquor pump of reverse starting, can be pressed into the liquid of fluid storage tank in described liquid delivery system or equipment and again utilize.
Its concrete control mode is: if the sensor of the performance of perception liquid record ducted liquid undesirable need recycle time, namely the signal of sensor makes going out pipe and extracting that pipe communicates, inlet pipe is closed, liquor pump forward starts out of recycle device by control circuit, liquid delivery system or device interior is extracted out together with the ducted liquid that retains of user side and is delivered in fluid storage tank; The sensor of perception liquid situation record retain liquid be evacuated after proper time, make liquor pump reverse starting, withdrawal liquid in fluid storage tank is pressed in the input duct of described liquid delivery system or equipment, until the sensor arranged in fluid storage tank perceives in fluid storage tank when not had liquid, closed by control circuit again and extract pipe and liquor pump out, stop program withdrawal liquid being pressed in liquid delivery system or equipment, recycle device returns to normal.Owing to decreasing component, the recycle device of this technological scheme more easily can be arranged on the inside of liquid delivery system or equipment.
Because above-mentioned each technological scheme has fluid storage tank as the buffer container of withdrawal liquid, the liquid of recovery can be returned in supply system or equipment when supply system or equipment normally work, thus less on the impact of the water influent pipeline of supply system or equipment, and can add that one-way valve is to eliminate the impact on supply system or equipment water influent pipeline completely in water influent pipeline.
As the alternative of above-mentioned recycle device parts, can by Circulation pipe and the three-way pipe extracting pipe joint out, the three-way pipe of delivery line and arm joint, one or several in the three-way pipe of the input duct joint of arm and described liquid delivery system or equipment changes electric T-shaped valve or electric change valve into, cancel the electric two-way valve relevant to this one or several three-way pipe (such as simultaneously, if eliminate the three-way pipe of delivery line and arm joint, namely cancel simultaneously on arm with the electric two-way valve of described delivery line on one end of fluid storage tank), direction is opened according to the SC sigmal control electric T-shaped valve of sensor or electric change valve by control circuit, reach same control object.
Another kind of easy technological scheme is: save fluid storage tank, Circulation pipe, arm and corresponding valve, in the pipeline directly delivery line being communicated to the liquid-inlet of described liquid delivery system or equipment or pipeline, the withdrawal liquid of extraction can be sent in the stoste liquid inlet pipe of described liquid delivery system or equipment equally like this, thus to reach the object of recycling.In order to prevent, in the liquid valve influent pump in input duct, preferably adding an one-way valve between liquor pump to input duct.The recycle device of this technological scheme can be arranged in the liquid entering hole of liquid delivery system or equipment or the pipeline of liquid outlet equally.
Aforementioned utilize liquor pump withdrawal liquid is directly pressed into several the automatic recovery utilized devices in the input duct of described liquid delivery system or equipment use the output pump pressure of liquor pump should be greater than pressure in liquid delivery system or equipment input duct.Pump pressure is exported in order to reduce needed for liquor pump, can improve control program, such as first the liquid of recovery is sent in the stoste liquid entering hole of described liquid delivery system or equipment, open the mortor operated valve in stoste liquid inlet pipe direction again, or pipeline or valve are suitably improved, the path of mortor operated valve or change arm is such as increased in liquid inlet pipe direction, make the mortor operated valve having to be controlled by the controller in stoste liquid inlet pipe direction (namely between the liquid flowing valve of the connectivity part liquid of recovery being sent into the pipeline of described liquid delivery system or equipment and the input duct of liquid delivery system or equipment to supply system or equipment), this mortor operated valve is closed when being sent among described liquid delivery system or equipment by the liquid of recovery, make reclaim liquid send into stoste liquid entering hole time and stoste liquid inlet pipe isolate.
The more easy technological scheme of one is in addition: the three-port structure cancelling carrying liqs choice of flow direction control valve, by the two ends of liquor pump directly with described inlet pipe with go out pipe and communicate, namely described liquor pump is directly serially connected in described inlet pipe and goes out between pipe, and liquor pump work time flow direction contrary with flow direction original in pipeline.The recycle device of this easy mode can be connected in series in the pipeline being arranged on liquid delivery system or equipment liquid outlet, but unfortunately can not the liquid of withdrawal liquid supply system or device interior.For not having liquid-storage device but the liquid delivery system at once processed ducted liquid or equipment, this recycle device is preferably connected in series and is arranged in the pipeline of its liquid entering hole.When open related valve, perception liquid situation sensor record liquid start to flow time, if the ducted liquid that the sensor of perception liquid properties records the outlet end of liquid delivery system or equipment meets the requirements, this liquor pump does not start, liquid delivery system or the satisfactory liquid of equipment regular supply; If the sensor of perception liquid properties record ducted liquid undesirable need recycle time, namely the signal of sensor makes liquor pump start by control circuit, to extract out to the liquid in user side pipeline again in recycle device to liquid delivery system or device interior pipeline and be pressed in input duct, and record after liquid is evacuated at the sensor of perception liquid situation, by control circuit, liquor pump is stopped, liquid delivery system or equipment can the satisfactory liquid of regular supply.The working pressure of the liquor pump of this technological scheme should be greater than the fluid pressure in input duct, and can allow when liquor pump does not start ducted liquid normal through, and this problem that to be prior art solved, as in the hot water cyclesystem of commercially available Sai Kela company or in the water heater of the Wan Jiale company band circulatory system the liquor pump that uses.
Aforesaid all recycle devices all can be advantageously used in the recovery of undesirable liquid in the pipeline of liquid delivery system or equipment, and must not transform the pipeline of whole supply system or equipment.Such as, be arranged on the jointing of the water-in and water-out pipeline near gas water-heater, electric water heater, solar water heater or boiler, and other pipelines of whole water heating system need not be changed.When the valve opening user side prepares to use hot water at every turn, this device can retain cold water automatically and quickly in recovery channel, and flow out the hot water being applicable to bathing very soon, so not only decrease the waste of water resources, bathing process can also be made more comfortable, quick.Even can also by this device integrated installation in the inside of solar water heater, electric water heater or gas water-heater, make with water heater all-in-one-piece, there is the water heater that cold water the automatic recovery utilizes function, like this, the volume of the complete equipment made is less, installs and uses more convenient.
In the bathroom that common liquid delivery system or equipment such as use boiler water supply or household water heater, usually there are multiple user side and corresponding pipeline.When using of the present invention, when unlatching hot water supply system or equipment and after opening valve by user formerly and starting recycle device of the present invention, lead in the pipeline of this user side, in recycle device and the cold water of hot water supply system or device interior has become satisfactory hot water after recovery, but also there is undesirable liquid and cold water in the lateral of another user side.If another user is that recycle device may can not reclaim again, and the liquid that another subscriber's outlet will be caused just to have flowed out like this is undesirable at the Open valve in shorter time just in use or after stopping using of user formerly.
In order to address this problem, following method can be adopted to operate: the valve first opening all user sides before use, then the valve of hot water supply system or equipment is opened, now, retain liquid undesirable needs recycle due to ducted, recycle device can retain ducted for multiple user side the undesirable liquid that retains in liquid and hot water supply system or device interior pipeline and all extracts out for re-using; When ducted liquid meets the requirements, hot water supply system or equipment get final product the satisfactory hot water of regular supply, all directly can flow out hot water in multiple user side pipeline.
Another kind of solution is: on the circuit of described controller, install a disposable signal button, this button by circuit within the regular hour (such as within 5 ~ 10 minutes) provide a single electrical signal (the time delay voltage signal such as provided by resistor capacitor circuit), when a new unlatching user side valve, what sensor recorded starts flowing (when opening a valve) because of liquid or accelerates flowing (at existing valve opening, when opening another valve again) and pressure diminishes or the signal such as flow velocity increase combines with above-said current signal, the signal that temperature-sensing element exports by the program that can be set by control circuit changes the undesirable signal of temperature (the signal upset such as exported by temperature-sensing element by above-mentioned voltage signal) at once into, thus again start recycle device once.Like this, when the valve of user side formerly is just closed soon, first click this button, newly open the valve of another user side again, still again recovering device can be started, by after water in the pipeline of user opened reclaim, and flow out after having reclaimed and meet the hot water of temperature requirement, when opening the valve of another user side in the time shorter after stopping using with the user solved formerly, water heater can not reclaim its ducted cold water problem, if user formerly uses water heater, click this button in the ban, when newly opening the valve of another user side again, the flow velocity of liquid is accelerated, sensor record because liquid accelerates flowing, pressure diminishes or flow velocity increases isopulse signal and above-said current signal and combines, the signal exported by temperature-sensing element changes the undesirable signal of temperature at once into, again start recovering device once, the water formerly and in rear user's pipeline opened also is reclaimed in a situation of use where by force user formerly, and after having reclaimed, flow out the hot water meeting temperature requirement, like this, just solve water heater after user formerly also opens the valve of another user side in use and can not reclaim the ducted cold water problem of this user side, just there is of short duration impact to the use first user.
Except above-mentioned disposable signal button, also on the circuit of described controller, a persistency signaling switch can be installed individually or simultaneously, this switch provides an electrical signal (such as voltage signal) by circuit always, what this signal and sensor when at every turn opening user side valve recorded starts to flow (when opening a valve) or accelerate to flow (having valve opening because of liquid, when opening another valve again) and pressure diminishes or the pulse signal of flow velocity increase combines, the signal that temperature-sensing element exports by the program that can be set by control circuit changes the undesirable signal of water temperature at once into.Like this, after opening this switch, user can make recycle device start once when new Open valve each time, is reclaimed by the water in the user's pipeline all opened, and after recovery completes, flows out the satisfactory hot water of temperature.Can not cold water problem in recovery channel when using water heater in the time shorter after the user when user of user above so also solved below uses water heater or above stops using, just all can there is of short duration impact to the use first user at every turn.
Also has a kind of preferred solution: to be arranged on by temperature-sensing element near each user side valve and it to be electrically connected with control circuit, like this, when opening the valve of wherein any one user side, if the temperature of water outlet is undesirable, recovering device can be started, water in the pipeline of opened user is reclaimed, and after having reclaimed, flows out the hot water meeting temperature requirement.
If change corresponding oxygen saturation sensor, CO by above-mentioned respectively into for the temperature transducer in the recycle device of hot water supply system or equipment 2saturation ratio sensor, pH sensor or low-temperature sensor etc., can be respectively used to liquid is carried out to oxygenation, adds CO 2, adjust pH or refrigeration after for the production of life liquid delivery system or equipment.
The control circuit of recycle device can add other corresponding part composition control devices, can also with the setting qualified limit of liquid properties or the parts of limits and corresponding display unit on controller.Use sensor and control mortor operated valve by control circuit, liquor pump is existing mature technology, the those of ordinary skill of electro-mechanical arts can be determined the concrete sensor, mortor operated valve, controller and the circuit (as used programmable controller) thereof that use completely according to actual needs and not need to pay performing creative labour, such as, adopt the sensor of 6N1003636926, CN1959287A, CN1693810A or CN2699185Y, mortor operated valve and controller.
The various technological schemes of foregoing liquid delivery system or equipment all can be applied in other fluid feed systems such as gas, flowing powder or equipment, and carry out necessary adaptation disposal by those of ordinary skill in the art according to the different situations of understood fluid.Such as gas, be easy to diffusion due to it and compress and be easy to mix with other fluids, therefore its storage container is different from the fluid storage tank communicated with air that liquid adopts, and should be closed container; As long as the pipeline opening of the pipeline of gas bleeding communicates with storage container from storage container, near the bottom that not necessarily will be placed in container as liquid; Can not necessarily to recycle device be made to enter working state by the flowing of fluid as liquid; When using recycle device, first do not open the valve of user side, but before or after opening gas supply system or equipment, namely start respective valves and the gas pump of recycle device, undesirable gas is reclaimed, until just open the valve of user side when the gas that gas supply system or equipment are supplied reaches requirement, the satisfactory gas of regular supply.
