Variable pressure valve wherein, it is a valve being arranged on ventilative interface, built-in two pistons movably, piston is according to Water in Water Tank not when overfill, piston moves down, and ventilative interface is communicated with atmosphere by this valve, at Water in Water Tank slightly in overfill, on piston, move the passage of closing with atmosphere, water tank is in a temporary transient closed state; Another piston changes mobile according to the pressure in heat storage water tank, exceed the predetermined pressure of variable pressure valve, and the piston of pressure relief opening is opened and carried out decompression protection water tank.
Cyclic permutation heat exchange wherein, it is a kind of heat-exchange method between heat storage water tank and heat collector, the method is a kind of multiple batches of interval heat exchange, after every batch of running water inflow system, warm water being first mixed into the part hot water recycling from heat storage water tank, the energy that middle warm water relies on running water itself removes to displace the hot water that has been heated to predetermined temperature in heat collector, replaced hot water enters into heat storage water tank and stores, the middle warm water of displacement is trapped in and in heat collector, waits for cyclic permutation next time, circulation and displacement are two aspects of a process, both start simultaneously, also stop simultaneously.
Working state of system and operation principle are described below, system initial state, main transfer valve is at state one, auxiliary transfer valve is at one grade, in heat collector, be full of the running water of low temperature, because the temperature of running water does not reach the predetermined temperature of attemperating unit, watering pipeline is stopped flowing by attemperating unit cut-off, heat storage water tank hollow.
Heat collector ceaselessly absorbs solar energy, water in heating heat collector, water temperature also constantly rises, but the water temperature in heat collector reaches the predetermined temperature of attemperating unit, water route switch in attemperating unit is opened, watering pipeline circulates again, under the pressure of running water itself, running water flows into from water inlet, flow through water mixing valve, because heat storage water tank does not now have hot water, the water that upper water mixing valve flows out from two-in-one outlet or the low temperature running water of single entrained gas, this water flows through main transfer valve, water Rapid Flow in former watering pipeline is to heat collector, the new water flowing into passes through attemperating unit the water that has been heated to predetermined temperature in heat collector, auxiliary transfer valve, push into heat storage water tank, the new water flowing into is because water temperature does not reach the predetermined temperature of attemperating unit, water route switch in attemperating unit cuts out watering pipeline, water route is ended again.This process is exactly the process of displacement heat exchange, and cold water displaces the hot water that has been heated to predetermined temperature in heat collector and enters heat storage water tank, waits for the arrival of displacement next time and itself be trapped in heat collector.
Heat collector on and on absorbs solar energy, water in heating heat collector, water temperature also constantly rises, but the water temperature in heat collector reaches the predetermined temperature of attemperating unit, water route switch in attemperating unit is opened, watering pipeline circulates again, under the pressure of running water itself, running water flows into from water inlet, flow through water mixing valve, because heat storage water tank now has had the hot water of constant temperature, the hot water of part sucks from the water sucking mouth of upper water mixing valve, in the valve body of mixing valve, the running water of low temperature and the hot water of suction are mixed into middle warm water, middle warm water flows out from the two-in-one outlet of upper water mixing valve, flow through main transfer valve, the new middle warm water flowing into passes through attemperating unit the water that has been heated to predetermined temperature in heat collector, auxiliary transfer valve, push into heat storage water tank, the new middle warm water flowing into is because water temperature does not reach the predetermined temperature of attemperating unit, water route switch in attemperating unit cuts out watering pipeline, water route is ended again.But this time heat exchange is from last different, and the water of this displacement is middle warm water, instead of cold running water, and middle warm water is to circulate out by the loop exit of heat storage water tank, and therefore this heat exchange is cyclic permutation heat exchange.As long as have water in heat storage water tank, heat exchange is then not always the case, and this heat exchange is till heat storage water tank water is full.This cyclic permutation heat exchange, because each heat collector is all that therefrom warm water starts heating, therefore the speed of heat exchange is faster, implication, the time that hot water stops in pipeline is shortened, pipeline just can extend, and the spacing of heat collector and heat storage water tank just can extend use, brings great convenience to the installation of separated solar water heater.
System with hot working, when by heat, native system provides two kinds with hot mode, a kind of be heat storage water tank completely under non-pressure state by heat; Another kind is the use heat of heat storage water tank under micro-pressure-bearing or half pressure-bearing or full artesian condition.

If without electric control pump, also wish the out hot water of higher temperature and pressure of system, native system adopts another kind of supplying hot water mode, i.e. and minute-pressure or half is pressed or full pressure-bearing hot-water supply, and different pressure-bearing modes is decided by the bearing capacity of heat storage water tank.
The panel knob rotating on switching makes winner's transfer valve at state two, and auxiliary transfer valve is at second gear.The state two of main transfer valve is that A interface is only communicated with D interface, water mixing valve in tap water flows, the water that running water and heat storage water tank loop exit flow into is mixed into middle warm water and flows out from the two-in-one outlet of valve, enter the A interface of main transfer valve, flow into the D interface of main transfer valve, be fed directly in heat storage water tank by " the former hot water outlet " of heat storage water tank, water level in the water lifting water tank flowing into, cause the variable pressure valve of installing at ventilation mouth, closed vent mouth, water tank is in temporary transient closed state.Water in heat storage water tank is flowing under the pressure of water, flow to " the former hot water inlet " of heat storage water tank, flow into a interface of auxiliary switching by pipeline, flow to again the d interface of auxiliary transfer valve, flow to the water sucking mouth of water pressurizing valve from d interface, finally flow to the two-in-one outlet of lower water pressurizing valve, inflow hot water pipeline.The former hot water outlet of the heat storage water tank under this state becomes " the new cooling water inlet " under new state, the former hot water inlet of heat storage water tank becomes " new hot water outlet ", hot water is to flow into after mixing with the water of heat storage water tank loop exit by running water, hot water is ejected, hot water is now to have pressure hot water, and the hot water flowing out, in the running water entrance situation of closing lower water pressurizing valve, be the constant temperature hot water of heat storage water tank itself exactly; If do not close the running water entrance of lower water pressurizing valve, the hot water flowing out is a kind of pressurization mixed hot water, and the pressure ratio of water flows to the pressure of the water of water tank and wants large.
The antifreeze job description of system, separated solar water heater is because heat collector and section of tubing are outdoor, when winter, temperature reduced, must consider antifreezely, and measures of prevent freezing of the present invention is, and main transfer valve is at state three, and auxiliary transfer valve is at one grade.Main transfer valve B interface is communicated with C interface, after C interface is communicated with the c interface of auxiliary transfer valve by pipeline, be communicated with the d interface of auxiliary transfer valve again, the water sucking mouth of d interface and lower water pressurizing valve links together, the negative pressure of water sucking mouth causes that two interfaces of attemperating unit are communicated with, pipeline is communicated with the atmosphere of the ventilation mouth of water tank by the ba interface of auxiliary transfer valve, form an emptying pipeline of complete water suction, by the suction of lower water pressurizing valve water sucking mouth, the corresponding pipeline being connected with water sucking mouth is all inhaled to sky, realize anhydrous antifreeze.
The invention has the beneficial effects as follows, a kind of brand-new two separated solar water heaters of pressing, have the ability of non-pressure hot-water supply and two kinds of supplying hot waters of pressure-bearing hot-water supply concurrently simultaneously, can according to the temperature of hot water in different use hot water conditions and heat storage water tank and hot water amount number, flexibly select.System has multiple duty, selects by mechanical knob, realizes full automatic upper water, heating, heat exchange, heat accumulation, antifreeze, non-pressure with hot water, pressure-bearing hot water.Adopt cyclic permutation heat exchange, realize the remote of heat collector and heat storage water tank, high efficiency heat exchange, heats at a high speed.System cost is low, and the realization under zero-power state makes separated solar water heater enter huge numbers of families, more energy-conservation.System provides at any time constant temperature hot water, heat storage water tank is placed into hot water point of application.

Operation principle of the present invention is further described according to diagram: the water up and down under non-pressure state, and main transfer valve is at state one, and AB is logical logical with CD; Auxiliary transfer valve is at one grade, and ab is logical logical with cd.The in the situation that of attemperating unit (103) conducting, running water flows into from water inlet (201), by water inlet pipe (401), flow on the one hand water mixing valve (107), also flow on the other hand lower water pressurizing valve (108), stopping with hot-water line (412) with under the state of hot water, lower water pressurizing valve (108) pipeline water is no longer mobile.The hot water that enters into the current of water mixing valve (107) and suck from the loop exit (206) of heat storage water tank (101) is mixed into warm water, flow out from the two-in-one outlet (210) of upper water mixing valve (107), by the AB interface of main transfer valve (105), flow into and displace pipe (402), enter the heat collector incoming interface (211) of heat collector (102), the own energy that middle warm water relies on running water flow into heat collector (102), the hot water that has been heated to predetermined temperature in heat collector (102), all push into and displace pipe (403), the ba interface of auxiliary transfer valve (106), hot water enters pipe (404) and enters in the heat storage water tank (101) that pipe links together with hot water, when central warm water self flow into the temperature control entrance (213) of attemperating unit (103), because the temperature of middle warm water does not reach predetermined temperature, the inner heat detector control water route switch of attemperating unit (103) cuts out water route, so far middle warm water is trapped in heat collector (102), heat collector (102) has been heated to the hot water of predetermined temperature, the overwhelming majority enters into the insulation of heat storage water tank (101) storage, and the process of such heat exchange is exactly cyclic permutation heat exchange.
Be trapped in the middle warm water in heat collector (102), rely on heat collector (102) constantly to absorb solar energy, promote the temperature of water, in the time that the temperature in heat collector (102) reaches predetermined temperature, attemperating unit (103) reopens, current restart to flow, and a new cyclic permutation heat exchange starts again.And so forth until the water of heat storage water tank (101) is full.
Open with the water valve in hot-water line (412) pipeline, running water flows into from the water inlet (208) of lower water pressurizing valve (108), due to the built-in special water stream channel of lower water pressurizing valve (108), water sucking mouth (209) at lower water pressurizing valve (108) produces the negative pressure lower than atmosphere, constant temperature hot water in heat storage water tank (101) flows out from hot water outlet (205) under the pressure of atmosphere, by hot water out pipe (410), the DC interface of main transfer valve (105), pipe (411) between valve, the cd interface of auxiliary transfer valve (106), the water sucking mouth of lower water pressurizing valve (108) flows into, be mixed into the hot water of suitable temperature with the running water in lower water pressurizing valve (108) valve body, flow out from the two-in-one outlet (210) of lower water pressurizing valve (108), enter into hot-water line (412).In the case can be lower than the constant temperature hot water temperature of heat storage water tank (101) itself from the hot water flowing out with hot-water line (412), but because heat storage water tank is a kind of higher constant temperature hot water, by lower water pressurizing valve (108) mixing of certainty ratio really, water temperature while making to use is just in time suitable, and the hot water that is out with the more benefit that water pressurizing valve (108) brings is at present a kind of hot water that has pressure.And lower water pressurizing valve (108) is a kind of full mechanical device, zero-power.If the hot water of certain more high pressure and temperature, can change an automatically controlled water pump lower water pressurizing valve (108).
The water of the present invention under artesian condition, as mentioned above, use hot water under non-pressure state, water temperature is a kind of hot water of suitable temperature, constant temperature hot water in non-heat storage water tank (101), hot water out has certain hydraulic pressure, the pressure of a kind running water, but hydraulic pressure can not be equal to the pressure of running water completely, if need hot water to be out equal to the hot water in heat storage water tank (101) completely, heat hydraulic pressure out is also equal to the pressure of running water completely, the invention provides the supplying hot water mode under a kind of pressure-bearing.The size of bearing capacity depends on the bearing capacity of heat storage water tank, and according to the bearing capacity of heat storage water tank, system can provide minute-pressure or half to press or total head supplying hot water.
Specifically at the ventilation mouth of heat storage water tank (101), a variable pressure valve is installed; this variable pressure valve is controlled the mobile piston in transformation valve body according to the water level in heat storage water tank (101); slightly overfill of water in heat storage water tank (101); variable pressure valve is just closed the passage with atmosphere; heat storage water tank (101) is in a temporary transient closed state, and variable pressure valve also has the pressure bearing according to water tank to carry out the function of decompression protection heat storage water tank (101).
Rotate the panel knob of main transfer valve and auxiliary transfer valve, main transfer valve is at state two, and auxiliary transfer valve is at second gear, and AD is logical logical with ad.Under this state, former hot water outlet (205) becomes " new middle warm water entrance ", and the hot water that running water and heat storage water tank loop exit flow out is mixed into middle warm water, is fed directly in heat storage water tank, removes to push the constant temperature hot water in heat storage water tank.Former hot water thermal water inlet (207) becomes " new hot water outlet ", the constant temperature hot water being extruded in heat storage water tank is mouthful outflow from then on, enter pipe (404) by hot water, flow into the ad interface of auxiliary transfer valve (106), flow to again the water sucking mouth of lower water pressurizing valve (108), if now close water valve (304), the hot water flowing out from the two-in-one outlet of lower water pressurizing valve (108) is exactly heat storage water tank constant temperature hot water completely, and the pressure of hot water determines the pressure of the middle warm water that enters heat storage water tank completely.If do not close water valve (304), hot water is out a kind of mixing water, and water temperature can reduce a bit, but heat hydraulic pressure out can exceed the pressure of the middle warm water that enters heat storage water tank.
Adopt under artesian condition with hot water, due to heat storage water tank (101) in this process heat storage water tank all the time for the state of full water, the cyclic permutation heat exchange meeting of system stops, under normal circumstances, need to adopt the water of using up in part heat storage water tank under non-pressure state, make the water in heat storage water tank no longer full, system just can start the work of cyclic permutation heat exchange.
