Fig. 1 is the schematic diagram of installing and using of existing solar water heater;

Fig. 2 is the structure chart of the utility model one valve;

Fig. 3 is the another kind of art cell structure of the utility model one valve.

Among Fig. 2, shell 17 is made the tubulose step, upper and lower have valve gap 16 and valve bottom 27 to connect respectively, offer running water water inlet 19 and housing corresponding with it (descending) mouth of a river of going up of side in addition on the shell, go up (descending) mouth of a river and pick out three-way body 32, be fixed on place, (descending) mouth of a river with screw 34, threeway branches out two the tunnel, outlet 8 is by last (descending) water pipe water receiving case, and outlet 13 connects shower.Overflow water inlet mouth 3 water receiving case overflow flow exports, water nozzle 3 is actively connected on the support 1, support 1 is connected on the shell body overflow water inlet, and connects with valve bottom 27 with screw 31, overflows water nozzle 23 in housing opposite side corresponding position and is connected in the housing overflow outlet.State shown in Fig. 2 is water state on water tank, this

moment spring

7,9 are in compression or half compressive state, spring 24 is in free state, running water enters housing by water inlet 19, by hole 37 corresponding with it on the valve pocket 18 corresponding circumferential slot 20 water inlets on spool again, and through the opposite side 37 ' water outlet of groove 20 by valve pocket hole 37, because check ball 10 is subjected to the compressing (spring 9 is positioned in the three-way body by position-limitting pin 33) of spring 9 in the threeway, be positioned on the step surface of valve pocket hole delivery port 37 ', spheroid 10 is rotated intake pressure and back pressure spring 9 makes spheroid 10 turbulences, water can flow into threeway by the dynamic clearance between ball and the hole, and 8 leading to water tank by outlet, another shower mouth 13 of threeway this moment is closed (being common water valve) by artificial valve port 12.When water on the water tank is full, water tank overflow is flowed in the hydroecium of being made up of elasticity epithelium 4 and support 1 in the valve casing 2 by spilling water caliber spilling water import 3, elastic membrane 4 is fixed on the support 1 by screw 29 by trim ring 30, water in the hydroecium 2 drains into inner chamber through exhaust (water) mouth 6, but the drain discharge of exhaust (water) mouth is less than the flow of overflow inlet 3, so the water in the hydroecium 2 increases rapidly, hydraulic pressure increases, when its hydraulic pressure during greater than the elastic force of spring 24, water pressure pushing epithelium 4 drives the drive link 25 that connects with it and passes through pin 26 and drives control levers 22 compression springs 24, control lever 22 is swung to the right around the fulcrum 36 that is fixed on the bearing 5, its bayonet socket and spool awl tail step is broken away from, spool 11 moves upward under the effect of spring 7, when the spool straight line that makes progress moves to valve gap 16 when spacing, be that stroke is L, this moment is because of moving on the intake chamber 20, left the position of inlet opening 37, so the water inlet path cuts off, automatically stop to go up water, steel ball 10 is on the outlet one side stage terrace that has withstood hole 37 under the pressure of spring 9, prevented of the backflow of water tank water by last (descending) water pipe, because water tank water is completely gone up water and is stopped, so no overflow water inlet, ponding in the hydroecium 2 is very fast 6 discharges by inner chamber and overflow outlet 23 through the hole, anhydrous back hydraulic pressure descends in the hydroecium 2, then in spring 24 recovery processs control lever is pushed into original position left.Owing to move on the spool, the radial direction through hole 21 on this moment spool also moves to and valve pocket hole 37 center-aligned, but this moment hole 21 direction not with hole 37 in the same way, differ 90 °, this moment is because of moving on the spool, so spool top knob 15 has also broken away from the stopper slot 14 on the valve gap.If this moment hydro-thermal need shower, open showering 12, then shower head 13 goes out hot water, as dislike water too hot, rotatable adjusting knob 15, spool 11 is rotated in valve pocket, when hole 21 begins to align with hole 37, promptly there is cold water to enter, when hole 21 and hole 37 axis complete matchings, cold water inflow maximum promotes balls 10 by hole 37 outlet and advances cold water, and leads to the shower outlet after hot water that water tank comes mixes, and cold and hot adjusting is promptly regulated cold water water inlet combined amount till suitable by the rotational angle of manual adjustments spool fully.The intact back of shower water on water tank, aim at as long as knob 15 is threaded to valve gap groove 14, no longer align with hole 37 in hole 21, and get back to the position of 90 ° of mutual deviations,, even spool move down and compress spring 7 make spool forecone move down backstage terrace again be stuck in the bayonet socket of control lever on to pressing down knob 15 this moment, groove 20 aligns with hole 37, the last water process that can repeat to begin this moment.The place that Fig. 3 is different with Fig. 2 is that the hydraulic pressure sensing body of overflow water inlet hydroecium is different, replace the elasticity epithelium with a mobile piston under the hydraulic pressure effect, after overflow enters piston cavity hydroecium 2, discharge by exhaust (water) hole 6, but exhaust (water) mouthful 6 flows less than overflow water inlet 3, so the pressure of hydroecium 2 increases rapidly, when hydroecium pressure during greater than the elastic force of spring 24, piston 4 moves to right, and by drive link 25 drive control levers 22 compressing springs 24, control lever and spool are broken off relations, and all the other processes are with Fig. 2 process.1 is piston bush, and fixing with screw 30 with housing, 26 is the locating hole of spring 24, and 29 is the control lever locating slot.

The utility model will be gone up water and close automatically, anti-backflow, and the hot and cold water regulatory function is closed in a valve and is finished, must trouble on the scene when the personnel that saved go up water, water tank stops to go up water after completely automatically, prevents when cutting off the water that water tank water from refluxing, saved the water source, it is also very convenient to use.
