Description
Technical field
The utility model relates to a kind of hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid that utilizes.
Background technique
Along with rapid economy development, various energy supplies are more and more nervous, and price is also more and more expensive, and solar energy has become the first-selection of people's cheap energy capable of using undoubtedly like this.At present, people utilize solar energy mainly to carry out hot water and generating, and it is minimum, most effective wherein to utilize solar energy to carry out the cost of hot water, can be used for having a bath, washing dish and heating etc. in the family.Utilizing solar water is a process that continues heating, so people generally will store through the water of solar energy heating in order to taking at any time at the indoor water storage tank that is provided with.Water storage tank mainly contains two kinds of sealing pressure storage type and opening gerotor types, and wherein, sealing pressure storage type water storage tank promotes hot water automatically according to the pressure of feeding cold water and outwards flows out, and is simple in structure, easy to use, but price is more expensive, and working life is shorter.
For the open containers that under atmospheric pressure outwards supplies water; Can know according to law of connected vessels; The liquid level that the outflow point that is connected with open containers must be lower than open containers could outwards supply water, and the outflow point is just big more with respect to the big more discharge pressure of liquid level drop of open containers.If both drops are very little or do not have a drop, even flow out point and be higher than under the situation of open containers liquid level, wanting to reach water outlet has pressure, so just must on the normal pressure outlet conduit, add a compression pump to reach the purpose of water outlet supercharging.At present, the solution of employing generally has two kinds, and a kind of is to adopt self-priming compression pump to add the mode of chain pressure switch.The pressure of supply water of self-priming compression pump is big, can guarantee to promote mechanical compression switch action message.The valve (water tap) that flows out point when eminence is when being unlocked, and the water supply line internal pressure reduces, and pressure switch is connected the compression pump power supply, compression pump just automatically pressurization outwards supply water.When flowing out the some valve closing, the water pipe internal pressure raises, and the pressure switch action is also cut off the compression pump power supply, and compression pump is shut down, and a work cycle finishes.The advantage of this controlling schemes is simple in structure; Can pressurize automatically to supply water or stop pressurization according to the switch that flows out the some valve and supply water, shortcoming be that mechanical compression switch control accuracy is lower, can make discharge pressure non-constant; Suddenly big or suddenly small phenomenon appears; Sometimes hot and sometimes cold phenomenon will occur when having a bath, and the work noise of self-priming compression pump is very big, is not suitable in indoor use.Another kind of solution is the control switch that the control compression pump is set on the valve that flows out point, and when valve opening, the compression pump power supply is switched on, thereby realizes the purpose that pressurization is supplied water; And in throttle down, the compression pump power supply is also closed simultaneously, can realize that also compression pump can open or close according to actual needs automatically.The advantage of this technological scheme is; Can select the compression pump of different sound level according to actual needs; Selectivity is bigger, and shortcoming is the valve (water tap) that needs to transform or change each outflow point on lavatory, kitchen and the balcony, and lays the control electric wire that connects valve and compression pump; The installation improvement project is huge, and very not attractive in appearance.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of rational in infrastructure to above-mentioned deficiency; The pressurization automatically that can hoist according to unlatching or the closing control lower fluid that eminence flows out the some valve is confessed or is stopped to confess; Control accuracy is high; Confess pressure stability, and the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid that utilizes easy for installation.
For solving the problems of the technologies described above; This utilizes the hoist structural feature of control gear of automatic transport of high-pressure liquid control low-pressure fluid to be: comprise the low-voltage tube that is connected with high-voltage tube one end; The low-voltage tube of high-voltage tube one side is an inflow segment; The low-voltage tube of high-voltage tube opposite side is for flowing out section; Compression pump by controller control is installed on the low-voltage tube, the high pressure valve by controller control is installed on the high-voltage tube, the low pressure valve of being controlled by controller is installed on the inflow segment or prevents the one-way valve that inflow segment flows backwards; Also comprise being arranged on and flow out the flow transducer that section goes up the detection flow velocity; Or be arranged on low pressure valve or one-way valve exports corresponding low-voltage tube or high pressure valve exports the pressure transducer on the corresponding high-voltage tube, or be separately positioned on the inflow segment the lowpressure stream speed sensors be arranged on the high-pressure spray speed sensors on the high-voltage tube, said flow transducer, pressure transducer, lowpressure stream speed sensors and high-pressure spray speed sensors all with corresponding being electrically connected of input/output terminal of controller.
This structure to utilize the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid be to confess or stop to confess through the pressurization automatically that realizes hoisting according to unlatching or the closing control lower fluid that eminence flows out the some valve of Electrocontrolled high-pressure driving structure; Control accuracy is high; Confess pressure stability, and easy for installation.
The Electrocontrolled high-pressure driving structure mainly comprises the high-voltage tube that is connected on the low-voltage tube, is convenient narration, and the low pressure pipeline section of high-voltage tube both sides is called inflow segment respectively and flows out section.Be connected with low-pressure fluid in the low-voltage tube, low-pressure fluid flows into from inflow segment, and flows out from flowing out section.Compression pump by the controller Control work is installed on the low-voltage tube, and the main effect of compression pump is under controller control, the pressurization of the low-pressure fluid in low-voltage tube back to be confessed through flowing out section.Be connected with high-pressure liquid in the high-voltage tube, high-pressure liquid flows into from high-voltage tube is terminal, and flows out from an end that is connected with low-voltage tube.Low pressure valve or one-way valve are installed on the inflow segment of low-voltage tube.The action of low pressure valve is controlled by controller, and the main effect of low pressure valve is the break-make of control inflow segment.The main effect of one-way valve is the flow direction of restriction inflow segment inner fluid, makes the fluid in the inflow segment flow and can not flow backwards to flowing out the section direction.Because the pressure of the pressure ratio low-pressure fluid of high-pressure liquid is high; Therefore; Through low pressure valve or one-way valve, can avoid the high-pressure liquid of elevated pressures to get in the inflow segment of low pressure valve or one-way valve front end, effectively ensured being independent of each other of low-pressure fluid input source and high-pressure liquid input source.High pressure valve by the controller Control work is installed on the high-voltage tube, and the main effect of high pressure valve is the break-make of control high-voltage tube under the driving of controller, thereby whether decision makes high-pressure liquid flow out from flowing out section through high-voltage tube.Being installed in the main effect of the sensor on low-voltage tube or the high-voltage tube, is pressure or the flow velocity that detects the pipeline inner fluid, and this testing signal is real-time transmitted to controller as the control foundation.
When practical application, the high-voltage tube input end is connected with high-pressure fluid source, just the section of outflow is terminal is connected with output valve with the output terminal of low-voltage tube, and with the input end of low-voltage tube just the inflow segment end be connected with open hood type container or lowpressure stream body source.When locating output valve and close, the low pressure valve on the low-voltage tube is a closed condition, and the high pressure valve on the high-voltage tube is an opening state.At this moment, high-pressure fluid source with high-pressure liquid in high-voltage tube feeds the outflow section of low-voltage tube, so the sensor that is installed on low-voltage tube and the high-voltage tube can send high pressure signal or zero flow velocity signal to controller.When the user opens output valve and needs release fluid, flow out section and suddenly reduce the while flow velocity with the high-voltage tube internal pressure and raise fast.After controller receives the flow velocity signal of pressure signal or rising of reduction; Promptly judging output valve is unlocked; Just control is closed high pressure valve and is opened low pressure valve and compression pump simultaneously, and like this, high-pressure liquid just stops outwards output and low-pressure fluid pressurizes to hoist under the effect of compression pump and confesses., the lowpressure stream body source has only the output of compression pump normal power-up in the whole path of confessing because hoisting; Do not have other controlling componenies or influence the parts of delivery pressure, therefore in whole pressurization output procedure, pressure controling precision is higher; Delivery pressure is constant, flow speed stability.The user is when closing the output valve of eminence behind the output fluid, and the circulation passage of low-pressure fluid is turned off, and the pressure of compression pump output section increases suddenly but import that section pressure descends and whole path flow velocity is reduced to zero.When controller receives pressure signal that sensor sends or flow velocity signal; Can shut down by the control compression pump; And control low pressure valve cutoff low pipe, control high pressure valve simultaneously and connect high-voltage tube, so that high-pressure liquid maintains the high pressure or zero flow velocity of compression pump output terminal; At this moment, this utilizes the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid to be in holding state.So just guaranteed sensor on high-voltage tube or the low-voltage tube can be in real time high pressure or zero flow velocity signal when controller transmits holding state; The output valve that has also just transmitted eminence to controller is in the signal of closed condition; When output valve is opened, be convenient to controller and in time receive start signal, guaranteed that effectively this utilizes the hoist rapidity of control gear action of automatic transport of high-pressure liquid control low-pressure fluid.When opening output valve next time, repeat said process.
Be installed in the sensor on low-voltage tube and the high-voltage tube, can adopt the sensor of detected pressures also can adopt the sensor that detects flow velocity.The sensor of detected pressures is installed on the low-voltage tube of low pressure valve or one-way valve outlet, perhaps is installed on the corresponding high-voltage tube of high pressure valve outlet.Because the corresponding low-voltage tube of low pressure valve or one-way valve outlet is a connected relation with the corresponding high-voltage tube of high pressure valve outlet; So both pressure are identical when static state; No matter the sensor of detected pressures is installed on the low-voltage tube of low pressure valve or one-way valve outlet correspondence; Also be mounted on the corresponding high-voltage tube of high pressure valve outlet, can both detect the hydrodynamic pressure of the corresponding low-voltage tube of low pressure valve or the one-way valve outlet high-voltage tube corresponding, just the hydrodynamic pressure of output valve input end with the high pressure valve outlet.When output valve was closed, high pressure valve was opened, the sensor of detected pressures to be exactly the pressure of high-pressure liquid self.When output valve was opened, the inner hydrodynamic pressure of output valve reduced, and controller just can be controlled and close high pressure valve and open compression pump and low pressure valve simultaneously this moment, the pressurization of low-pressure fluid was confessed realizing.Emit when closing the eminence output valve behind a part of low-pressure fluid, if the sensor of detected pressures is positioned at the compression pump outlet, then pressure can suddenly raise, if the sensor of detected pressures is positioned at the compression pump inlet, the pressure that then detects can suddenly reduce.Like this, controller just can be judged the output valve that the user has turn-offed eminence, just controls the compression pump shutdown and turn-offs low pressure valve, opens high pressure valve simultaneously to keep the inner high pressure of output valve.
The sensor that detects flow velocity can be only to be installed in low-voltage tube to flow out the flow transducer on the section, also can be to be installed in the lowpressure stream speed sensors on the low-voltage tube inflow segment respectively and to be installed in the high-pressure spray speed sensors on the high-voltage tube.For the lowpressure stream speed sensors on only being installed in low-voltage tube outflow section, when output valve was opened, flow velocity became big gradually by zero, and controller control is at this moment closed high pressure valve and opened compression pump simultaneously and open low pressure valve, to low-pressure fluid pressurization output.When output valve was closed, the checkout value of flow transducer gradually became zero, and controller control this moment is opened high pressure valve and closed compression pump simultaneously and close low pressure valve.As far as be installed in respectively on the low-voltage tube inflow segment the lowpressure stream speed sensors be installed in the high-pressure spray speed sensors on the high-voltage tube; When output valve is opened; The flow velocity that the high-pressure spray speed sensors detects becomes big gradually by zero, and this moment, high pressure valve was closed in controller control, and judged through the testing signal of high-pressure liquid sensor whether high pressure valve closes; Open compression pump simultaneously and open low pressure valve, to low-pressure fluid pressurization output.This moment, the checkout value of lowpressure stream speed sensors raise by zero gradually, and controller can judge that according to this checkout value whether compression pump and low pressure valve are opened, and have played the effect of detection feedback.When output valve was closed, the checkout value of lowpressure stream speed sensors gradually became zero, and controller control this moment is opened high pressure valve and closed compression pump simultaneously and close low pressure valve, to keep the inner high pressure of output valve.
Utilize high-pressure liquid control low-pressure fluid to hoist the control gear of automatic transport when being applied to household solar heat water this; Can directly be serially connected in the running water pipe, and the inflow segment end is connected with the open type water storage box of solar water heater flowing out section end and high-voltage tube end.Because solar energy is worked by day always; So can utilize the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid daytime through this; The solar water of confessing with pressurizeing replaces tap water to heat, have a bath, wash one's hands, do washing or washes dish; Not only energy-conservation, more comfortable with coolant-temperature gage, and help to save washing powder etc.
Above-mentioned explanation is that the low pressure valve of being controlled by controller with installation on the low-voltage tube inflow segment is that example describes, and when practical application, also can use with compression pump and flow to consistent one-way valve replacement, and role is consistent, no longer carefully states at this.
As improvement; Said low-voltage tube and high-voltage tube are arranged in the open hood type container; The open hood type container outer wall is provided with intake channel and the outlet pipe that is communicated with the open hood type container inner chamber; Intake channel is inner to link together with the end of high-voltage tube away from low-voltage tube, and outlet pipe is inner to link together with flowing out the end of section away from inflow segment, and inflow segment extends to the open hood type container intracavity bottom away from an end that flows out section.
Low-voltage tube and high-voltage tube are arranged in the open containers; Not only can extract the fluid in the open containers through compression pump; But also can utilize the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid to cover up this with open containers, more attractive in appearance in appearance.Through being arranged on intake channel and the outlet pipe on the open containers outer wall; Can utilize the hoist control gear serial connection of automatic transport of high-pressure liquid control low-pressure fluid to be installed on the high-pressure fluid pipes this; And the low-pressure fluid that has characteristics such as high temperature or low temperature in the open containers confessed after pressurizeing automatically, install or use all very convenient.
As further improvement, inflow segment is equipped with filter away from an end that flows out section.

Embodiment
Specific embodiment one: as shown in Figure 1, present embodiment is that example is elaborated for hot water.This utilizes the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid to comprise the low-voltage tube 1 that is communicated with the low pressure hot water source, and in the present embodiment, low-voltage tube 1 input end links together with the uncovered water tank that is loaded with hot water.One end of low-voltage tube 1 middle part and high-voltage tube 3 links together, and is convenient narration, and the low-voltage tube of high-voltage tube 3 both sides is called inflow segment 11 respectively and flows out section 12 for 1 section, and hot water flows into from flowing out section 12 from inflow segment 11 and flows out.Compression pump 2 is installed on the low-voltage tube 1, and compression pump 2 is by controller 7 Control work.The main effect of compression pump 2 is under controller 7 controls, the pressurization of the low pressure hot water in the low-voltage tube 1 back to be hoisted or the water of heat supply at a distance through flowing out section 12.The high-voltage tube 3 terminal running water pipes that connect just are connected with tap water in the high-voltage tube 3 like this, and tap water is from high-voltage tube 3 terminal inflows, and the end inflow low-voltage tube 1 from being connected with low-voltage tube 1.Whether outwards outflow section 12 output valves 17 terminal and eminence or distant place of low-voltage tube 1 link together, can control through operation output valve 17 and flow out the outflow of the interior water of section.On the inflow segment 11 of low-voltage tube 1 low pressure valve 4 is installed, the action of low pressure valve 4 is by controller 7 controls.The main effect of low pressure valve 4 is break-makes of control inflow segment 11 under the control that controller is used, thereby realizes the control to hot water in the inflow segment 11.The pressure of the pressure ratio low pressure hot water of tap water wants high under nature; Therefore; Through closing low pressure valve 4, can avoid the tap water of elevated pressures to get in the inflow segment 11 of low pressure valve 4 front ends, effectively ensured being independent of each other of low pressure hot water input source and tap water input source.High pressure valve 5 by controller 7 Control work is installed on the high-voltage tube 3, and the main effect of high pressure valve 5 is break-makes of control high-voltage tube 3 under the driving of controller 7, thereby realizes that tap water is through high-voltage tube 3 inflow and outflow sections 12.On the outflow section 12 flow transducer 6 is installed, the main effect of flow transducer 6 is to detect the flow velocity that flows out section 12 interior water, and this testing signal is real-time transmitted to controller 7 as the control foundation.
When output valve 17 was closed, the low pressure valve 4 on the low-voltage tube 1 was a closed condition, and the high pressure valve 5 on the high-voltage tube 3 is an opening state.At this moment, running water pipe feeds tap water in the outflow section 12 of low-voltage tube 1 through high-voltage tube 3, so being installed in the flow transducer 6 detected flow velocity signals that flow out on the section 12 is zero, and sends this signal to controller 7.When the user opens output valve and needs water; Running water pipe can outwards supply tap water earlier through high-voltage tube 3 and outflow section 12; But outflow this moment section 12 suddenly reduces simultaneously with high-voltage tube 3 internal pressures, and flow velocity raises fast, and flow transducer 6 sends this flow velocity signal to controller 7.After controller 7 receives the flow velocity signal of this rising; Promptly judging output valve is unlocked; Just control closes that high pressure valve 5 is opened low pressure valve 4 simultaneously and to compression pump 2 power supply, and like this, tap water just stops outwards output and low pressure hot water is pressurizeed to hoist under the effect of compression pump 2 and confessed., the low pressure hot water source has only the output of compression pump 2 normal power-up in the whole path of confessing because hoisting; Do not have other controlling componenies or influence the parts of delivery pressure, therefore in whole pressurization output procedure, pressure controling precision is higher; Delivery pressure is constant, flow speed stability.During the close outflow valve door, the circulation passage of low pressure hot water is turned off after the user emits hot water, because also outage of compression pump 2, the pressure of compression pump 2 output sections can increase, import section pressure suddenly and can descend, but that whole path flow velocity is reduced to is zero.At this moment, flow transducer 6 can send controller 7 to by zero flow velocity signal.When controller 7 receives the flow velocity signal that sensor sends; Can shut down by control compression pump 2; And control low pressure valve 4 cutoff low pipes 1, control high pressure valve 5 simultaneously and connect high-voltage tube 3, so that the tap water in the running water pipe in time adds to high-voltage tube 3 and flows out in the section 12; With high pressure or zero flow velocity that keeps water in the compression pump 2 output terminal pipelines, so that flow transducer 6 can in time detect this start signal through testing the speed when opening output valve next time.So just guaranteed that flow transducer 6 transmits flow velocity signal accurately to controller 7 in real time, also just transmitted the output valve unlatching of eminence or the signal of closing in real time, exactly, guaranteed the promptness of heat supply water to controller 7.When opening output valve next time, repeat said process.
Embodiment two, as shown in Figure 2, this mode of execution and mode of execution one are roughly the same, and difference is that the quantity of flow transducer is two, i.e. lowpressure stream speed sensors 14 and high-pressure spray speed sensors 15.Wherein, lowpressure stream speed sensors 14 is installed on low-voltage tube 1 inflow segment 11, and high-pressure spray speed sensors 15 is installed on the high-voltage tube 3, and lowpressure stream speed sensors 14 all is electrically connected with controller 7 input ends with high-pressure spray speed sensors 15.When output valve is opened; High-pressure spray speed sensors 15 detects high-voltage tube 3 interior tap water flow velocities and becomes big gradually by zero; This moment, controller 7 was closed high pressure valve 5 according to this flow velocity signal control; And whether be zero flow velocity or judge near zero flow velocity whether high pressure valve 5 closes through this sensor signal, guaranteed the reliability of high pressure valve 5 actions.Open compression pump 2 simultaneously and open low pressure valve 4, to low pressure hot water pressurization output.The checkout value of lowpressure stream speed sensors 14 raises by zero gradually at this moment, and controller 7 can judge according to this checkout value whether compression pump 2 and low pressure valve 4 are opened, and have played the effect of detection feedback, has guaranteed the reliability of compression pump and low pressure valve 4 actions.When output valve was closed, the checkout value of lowpressure stream speed sensors 14 gradually became zero, and controller 7 was closed compression pump 2 simultaneously and closed low pressure valve 4 according to this testing signal control unlatching high pressure valve 5 this moment, the inner high pressure of output valve during with the maintenance holding state.
Embodiment three; As shown in Figure 3; This mode of execution and mode of execution one are roughly the same; Difference is that this utilizes high-pressure liquid control low-pressure fluid to hoist the sensor that control gear adopted of automatic transport for detecting the pressure transducer 16 of pipeline pressure, and pressure transducer 16 is installed on the low-voltage tube 1 of low pressure valve 4 outlets.When concrete production, also can pressure transducer 16 be installed on the corresponding high-voltage tube 3 of high pressure valve 5 outlets.Because the corresponding low-voltage tube 1 of low pressure valve 4 outlets is connected relations with the corresponding high-voltage tube 3 of high pressure valve 5 outlets, so both pressure are identical when static state.No matter pressure transducer is installed on the corresponding low-voltage tube 1 of low pressure valve 4 outlets; Also be mounted on the corresponding high-voltage tube 3 of high pressure valve 5 outlets; Can both detect the hydrodynamic pressure of the corresponding low-voltage tube 1 of the low pressure valve 4 outlets high-voltage tube 3 corresponding, just the hydrodynamic pressure of output valve input end with high pressure valve 5 outlets.When output valve was in closed condition, high pressure valve 5 was in opening state, and running water pipe is connected together through high-voltage tube 3 and low-voltage tube 1, so the detected force value of pressure transducer this moment is exactly the pressure of tap water self.When output valve was opened, tap water flowed out through high-voltage tube 3 and outflow section 12, and the inner hydrodynamic pressure of output valve reduces.After pressure transducer 6 detects the pressure signal of this reduction, just send this pressure signal to controller 7.Controller 7 just control and was closed high pressure valve 5 and open compression pump 2 and low pressure valve 4 simultaneously this moment, with realization the pressurization of low pressure hot water was confessed.When the user emits behind the hot water close outflow valve door, because the sensor of pressure 16 is positioned at the outlet side of compression pump 2, so pressure can suddenly raise.At this moment, controller 7 will be judged the buttoned-up information of output valve according to this elevated pressure signal, and like this, controller 7 will be controlled high pressure valve 5 and open, controls low pressure valve 4 and close and cut off compression pump 2 power supplys and get into holding state.When reality is used; If compression pump is positioned at the low pressure valve waterexit end; Also can pressure transducer be installed on the low-voltage tube 1 between compression pump 2 inlets and low pressure valve 4 outlets; During the close outflow valve door, pressure transducer 16 detected pressure can suddenly be reduced near the pressure under the hot water nature in the case.At this moment, controller 7 still can be judged the output valve that the user has turn-offed eminence, can control compression pump 2 shutdown equally and turn-off low pressure valve 4, opens high pressure valve 5 simultaneously to keep the inner high pressure of output valve.
Above-mentioned each embodiment is that the low pressure valve of being controlled by controller 7 with installation on low-voltage tube 1 inflow segment 11 4 is that example describes, and when practical application, also can use with compression pump 2 and flow to consistent one-way valve replacement.The main effect of one-way valve is the flow direction of restriction inflow segment 11 inner fluids, makes the fluid in the inflow segment 11 flow and can not flow backwards to flowing out section 12 directions, has effectively avoided tap water to pour in down a chimney the situation of hot water.
As shown in Figure 4; When concrete production; Can low-voltage tube 1 and high-voltage tube 3 all be arranged in the open hood type container 8, inflow segment 11 extends to open hood type container 8 intracavity bottoms away from an end that flows out section 12, and away from an end that flows out section 12 filter 13 is installed at low-voltage tube 1 inflow segment 11.Through filter 13, can the interior low pressure hot water of pairs of openings container filter, effectively ensured the turbidity test of output fluid.The intake channel 9 and the outlet pipe 10 that are communicated with open hood type container 8 inner chambers are set on open hood type container 8 outer walls, and intake channel 9 the inners link together with the end of high-voltage tube 3 away from low-voltage tube 1, and outlet pipe 10 the inners link together with outflow section 12 ends away from inflow segment 11.So not only can extract the low pressure hot water in the open containers, but also can utilize the hoist control gear of automatic transport of high-pressure liquid control low-pressure fluid to cover up this with open containers through compression pump 2, more attractive in appearance in appearance.Through being arranged on the intake channel 9 and outlet pipe 10 on the open containers outer wall; Can utilize the hoist control gear serial connection of automatic transport of high-pressure liquid control low-pressure fluid to be installed on the water supply pipe this; So just can the low pressure hot water that have hot properties in the open containers be confessed after pressurizeing automatically, installation or use are all very convenient.
