The working principle of heat energy water energy converter (14) is such: when in the working medium A heater (5-2) working medium of constant weight being arranged, because action of gravity is sunk in elevated temperature heat tank (5), subsequently by after the high-temperature water heating, working medium constantly gasifies in it, the working medium of vaporization constantly enters working medium work A chamber (14-7) by working medium delivery pipe (13), because working medium work A chamber (14-7) thus pressure increases symmetrical piston is constantly moved to symmetrical A piston (14-2) direction, at this moment there are two kinds of situations to occur, the one, the working medium of lining, working medium work B chamber (14-8) will begin constantly to reflux to working medium B heater (14-3) lining by working medium delivery pipe (12), the 2nd, volume-variation A chamber (14-11) is along with symmetrical piston constantly moves, volume is constantly reducing, its internal pressure constantly increases, under the effect of this pressure, after the current of lining, volume-variation A chamber (14-11) or air-flow obtain pressure energy, by unidirectional outlet valve (14-15), heat energy water energy converter outlet pipe (16), enter water conservation reservoir (1), meanwhile, volume-variation B chamber (14-12) along with the continuous mobile volume of symmetrical piston in continuous increase, its internal pressure is constantly reducing, after pressure was reduced to negative pressure, the water of following water conservation reservoir (2) lining will pass through heat energy water energy converter inlet valve (17), unidirectional inlet valve (14-3) enters volume-variation B chamber (14-12).Along with above-mentioned working procedure constantly continues, when symmetrical piston to symmetrical A piston (14-2) direction move arrive endpoint location after, at this moment two kinds of situations have also appearred simultaneously, the one, most working medium of working medium A heater (5-2) lining have entered working medium work A chamber (14-7), because the weight of working medium A heater (5-2) significantly reduces, float to the water surface in high-temperature water, working medium stops heating in it, working medium A heater (5-2) stops to carry vaporization working medium to working medium work A chamber (14-7), and symmetrical piston is also stopped to moving of symmetrical A piston (14-2) direction.At this moment, the working procedure that the working medium of lining, working medium work B chamber (14-8) refluxes to working medium B heater (14-3) lining also stops, and at this moment working medium B heater (14-3) sinks in high-temperature water owing to weight increases beginning.Second kind of situation be when symmetrical piston to symmetrical A piston (14-2) direction move arrive endpoint location after, symmetry A piston (14-2) just in time reaches the position of turnover tank (14-10), paddle hole (14-9) and turnover tank (14-10) are connected, at this moment the pressure water of lining, volume-variation A chamber (14-11) enters rapidly at the inboard working medium cooler (14-6) of symmetrical A piston (14-2), and the working medium temperature of lining, the A of working medium work at this moment chamber (14-7) has also reached the highest, its energy has also been changed and has been finished, need cooling cooling rapidly, carry out necessary preparatory work for working medium refluxes to working medium A heater (5-2) lining.The working medium heat of lining, working medium work A chamber (14-7) is delivered to this working medium cooler (14-6) rapidly, and water temperature raises in it.Ensuing working procedure is because aforementioned working medium B heater (14-3) beginning is sunk in high-temperature water, working medium is by constantly heating vaporization in it, working medium after the vaporization constantly enters working medium work B chamber (14-8) by working medium delivery pipe (12), because lining, working medium work B chamber (14-8) pressure increases, thereby symmetrical piston is constantly moved to symmetrical B piston (14-3) direction, because symmetrical piston moves to symmetrical B piston (14-3) direction, (14-11) forms negative pressure rapidly in volume-variation A chamber, under the effect of this negative pressure, the high-temperature water of working medium cooler (14-6) lining in symmetrical A piston (14-2) is inhaled into working medium work A chamber (14-7), paddle hole (4-9) and turnover tank (14-10) communication passage disconnect afterwards, this cooler sealing.Because the suction function of volume-variation A chamber (14-11), water in the following water conservation reservoir will enter volume-variation A chamber (14-11) by heat energy water energy converter intake pipe (17), gate valve (14-16) and unidirectional inlet valve (14-10), and purpose is for next step this current pressurization to be risen to the ready work of water conservation reservoir (1).When vacuum chamber (3-4) when needing suction air, closing gate valve (14-16) is opened gate valve (11), the air of vacuum chamber (3-4) lining can be drawn into volume-variation A chamber (14-11).When need kept the degree of vacuum of vacuum chamber (3-4) lining, closing gate valve (11) was opened gate valve (14-16) and is got final product.When symmetrical piston to symmetrical B piston (when the 14-3 direction moves, volume-variation B chamber (14-12) volume reduces pressure and raises, water from water conservation reservoir (2) suction down will rise to water conservation reservoir (1) by unidirectional outlet valve (14-15) and heat energy water energy converter outlet pipe (16) in it under the promotion of this pressure like this.The working medium of the A of working medium work at this moment chamber (14-7) also can constantly reflux to working medium A heater (5-2) lining.When symmetrical piston moves when arriving end points to symmetrical B piston (14-3) direction, working medium A heater (5-2) is because the weight increase, in the high-temperature water of elevated temperature heat tank (5) lining, sink, its working procedure can repeat above-mentioned working procedure again subsequently, move in circles like this, heat energy water energy converter (14) can realize that the thermal power transfer that constantly will obtain from elevated temperature heat tank (5) lining becomes mechanical energy, under the effect of mechanical energy, will descend the water of water conservation reservoir (2) to rise to the savings of water conservation reservoir (1) lining again, thereby finish the conversion of mechanical energy to the water energy.

In above-mentioned diagram; though having enumerated preferred embodiment of the present invention is illustrated; but it is well-known; should not limit right protection scope of the present invention on the contrary by this embodiment; that is any engineering science researcher who is familiar with this innovation point is if use the main feature of the present invention; carry out the change of some details, all must belong to scope of patent protection of the present invention.
