Be provided with the system of operating a switch, kickboard system, movable wedge system and water inlet valve control system thereof in the storage tank 6.The system of operating a switch is positioned at the upper end of storage tank 6, and is connected with the kickboard system, and the kickboard system places in the storage tank 6, and the system of operating a switch can spur the kickboard system and in storage tank 6, slide up and down; Movable wedge system and water intaking valve control system are positioned at a lateral ends of storage tank 6, and the kickboard system drives the movable wedge system, intake in storage tank 6 thereby the water inlet valve control system that links to each other with the movable wedge system is opened.Storage tank 6 can be installed in the body of wall that mixes water valve 1 top, and the volume size of storage tank 6 can be according to the on-demand customization of pipeline situation.The cold water that gets into storage tank 6 can be under the effect of himself energy stored and kickboard gravity and spring powered, is back to mix in the water valve 1 and the realization reuse.
The system of operating a switch comprises power spring 11, fixed pulley 12 and stay cord 13.Fixed pulley 12 comprises 2, a top place of being fixed in storage tank 6, and another is fixed in the center of top place of storage tank 6; Stay cord 13 is connected on the kickboard 7 in the kickboard system through these 2 fixed pulleys 12; Power spring 11 1 ends are fixed in the center of top place of storage tank 6, and the other end is fixed on the kickboard 7 in the kickboard system.
The kickboard system comprises kickboard 7, little floating plug 23 and first support bar 24.Kickboard 7 places the bottom in the storage tank 6, can in storage tank 6, move up and down, and in the inboard of storage tank 6, when kickboard 7 moves and storage tank 6 contact positions are provided with rubber mount 10, to guarantee its sealing; Kickboard 7 is provided with the aperture that supplies little floating plug 23 to embed; Little floating plug 23 is fixed on first support bar 24 and can moves up and down along it, also is provided with rubber mount 10 between the little floating plug 23 and first support bar 24, to guarantee its sealing; First support bar 24 is fixed in the side in the storage tank 6.
The movable wedge system comprises movable wedge 15, water outlet pull bar 17 and first return spring 16.Movable wedge 15 places in the storage tank 6 and is fixed on second support bar 9 of water valve control system into; Water outlet pull bar 17 is fixed on the movable wedge 15, and first return spring, 16 1 ends are fixed on the movable wedge 15, and the other end is fixed on the sidewall of storage tank 6.
As shown in Figure 2, the water inlet valve control system comprises second support bar 9, ball valve 14, fixed bar 19, second return spring 21, fixing rivet 22, ratchet 18 and ratchet drives sheet 20.Second support bar 9 is fixed in the opposite side of storage tank 6; Ball valve 14 is fixed in the bottom of second support bar 9 and is arranged in storage tank water inlet pipe 4; Ratchet 18 is fixed on the top of second support bar 9; Ratchet drives sheet 20 1 ends are fixed on the movable wedge 15 by fixing rivet 22, and the other end links to each other with ratchet 18; Fixed bar 19 is fixed on the movable wedge 15 through fixing rivet 22; Second return spring, 21 1 ends are connected with fixed bar 19, and the other end is connected with ratchet drives sheet 20.
A kind of use of water heater backflow water saving fixtures, comprise open before, pulling stay cord, water inlet process, water inlet finish, exiting water process, water outlet finish six processes, like Fig. 3-shown in Figure 8, carries out concrete explaination in the face of each process down:
A. kickboard 7 is positioned at storage tank 6 bottommosts before opening, and power spring 11 is nature elongation attitude; Movable wedge 15 is in low order end under 16 effects of first return spring, second return spring 21 presents nature elongation attitude, and fixed bar 19, ratchet 18 and ratchet drives sheet 20 are in resting state;
B. after spurring stay cord 13; On beginning, kickboard 7 moves, when kickboard 7 moves to movable wedge 15 positions, because the lozenges of movable wedge 15 contacts with kickboard 7; Thereby movable wedge 15 stressed motions backward (just the side wall surface towards storage tank 6 moves); And then drive ratchet 18 rotations, and ball valve 14 is slowly opened, the cold water in the hot-water line 2 gets in the storage tank 6.In this process, power spring 11, first return spring 16 and second return spring 21 constantly are compressed;
C. when kickboard 7 rose to movable wedge 15 tops, movable wedge 15 is self-return under the effect of first return spring 16, loosened stay cord 13, and kickboard 7 just in time is arranged on the movable wedge 15; 14 complete openings under the drive of ratchet 18 of ball valve, water progresses under the elevated tank or the pressure of city planting ductwork in the storage tank 6 of kickboard 7 bottoms, and little floating plug 23 rises with the water surface.Because whole storage tank 6 is an airtight device, so get in the process of storage tank 6 when cold water, the gas in the storage tank 6 constantly is compressed, and air pressure and hydraulic pressure after compression reach equal;
When D. air pressure after compressing and hydraulic pressure reached balance, water inlet finished.In the water inlet process, the water surface constantly rises, and little floating plug 23 progresses in the corresponding aperture of kickboard 7, or the user is not before little floating plug 23 gets into aperture, just spurs water outlet pull bar 17 and makes into that water finishes in advance;
E. after the user spurs water outlet pull bar 17, drive movable wedge 15 and move backward, kickboard 7 can move downward, and makes the water of storage tank 6 get into mixed water valve 1 through storage tank outlet pipe 5, thereby realizes reuse; Because moving backward, movable wedge 15 drives ratchet 18 rotations simultaneously; Make ball valve 14 on the storage tank water inlet pipe 4 close thereupon rotating that (ball valve is equivalent to a ball and has opened a hole; 90 ° of revolutions just can realize that ball valve closes by being opened to), storage tank 6 no longer water inlet in this uses like this.The outflow head of storage tank outlet pipe 5 is the head sum that air pressure and kickboard gravity and spring force are provided in this process;
F. this moment, whole device returned to reset condition again, and kickboard 7 is positioned at storage tank 6 bottommosts, and power spring 11 is nature elongation attitude; Movable wedge 15 is in low order end, and first return spring 16 presents nature elongation attitude; Fixed bar 19, second return spring 21, ratchet 18 and ratchet drives sheet 20 also all are in initial conditions.
The above-mentioned description to embodiment is can understand and use the present invention for ease of the those of ordinary skill of this technical field.The personnel of skilled obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not breaking away from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
