Among the figure: 1 mixes water valve, and 11 mix water valve handle, 16 stators, 161 hot water inlets, 162 cooling water inlets, 163 cooling water outlets, 164 mix water out, 17 rotors, 171 mix tank, 172 cold water discharge control flumes, 2 cold water pipes, 3 hot-water lines, 4 running water pipes, 5 water nozzles, 6 pressure limiting valves, 61 water inlets, 62 pressure limiting apertures, 63 delivery ports, 7 relief valves, 8 water tanks.
The specific embodiment
As shown in Figure 1, the cold water pipe 2 that this constant voltage water heater mainly comprises water tank 8, is connected with water tank inlet, the hot-water line 3 that is connected with water outlet of water tank.Wherein be connected with pressure limiting valve 6 between cold water pipe and the water tank, as shown in figure 11, be communicated with by a pressure limiting aperture 62 between the water inlet 61 of pressure limiting valve and the delivery port 63, the diameter of pressure limiting aperture is about 1～3mm, and concrete pore size needs to set according to different hydraulic pressure.Because the effect of pressure limiting valve makes that the water yield that enters and be ejected is in a basic balance, no pressure in 8 water tanks.The bottom of water tank is communicated with pressure-relief valve 7, in case the water tank internal pressure is crossed conference by its release, further guarantees safe in utilization.
Wherein cold water pipe 2, hot-water line 3, running water pipe 4, water nozzle 5 are connected on four interfaces of a mixed water valve 1.
The spool that mixes water valve comprises stator 16, rotor 17.As Fig. 2, shown in Figure 3, its stator is provided with cooling water inlet 162, hot water inlet 161, mixes water out 164, cooling water outlet 163.Wherein cooling water inlet 162 is connected with running water pipe 4, and hot water inlet 161 is connected with hot-water line 3, mixes water out 164 and is connected with water nozzle 5, and cooling water outlet 163 is connected with cold water pipe 2.As Fig. 4, Fig. 5, shown in Figure 6, its rotor is provided with the mixed tank 171 that cooling water inlet, hot water inlet can be communicated with mixed water out respectively, and rotor is provided with the cold rinse bank 172 that cooling water inlet, cooling water outlet can be communicated with.The bottom land of cold rinse bank 172 is a slope shape, and the bottom land incline direction is from deepening gradually to the other end near cooling water inlet 162 1 ends; Like this, it is many more that cold rinse bank overlaps with cooling water inlet, and the cold water that enters cold rinse bank is many more, promptly increases the cold water flow velocity, realizes the convenient cold water flow that flows into water tank of regulating.During use two spools are attached most importance to closing and be installed in the valve body, as shown in Figure 7.
Before using for the first time, at first cold water is filled water tank, then heating.
During use, operation mixes water valve handle 11, cold water is entered by running water pipe 4 mix water valve 1.Rotating mixed water valve handle drive rotor wherein then rotates together.
As shown in Figure 7, when cooling water inlet 162, the hot water inlet 161 of stator is communicated with the mixed tank 171 of rotor respectively, this moment, the cooling water outlet 163 of stator also was communicated with the cold rinse bank 172 of rotor.At this moment, enter a cold water part of mixing water valve and enter water tank by cooling water inlet 162, cold rinse bank 172, cooling water outlet 163, cold water pipe 2.Hot water in the water tank is ejected thereupon, flows to water nozzle by hot-water line 3, hot water inlet 161, mixed water out 164.So just, can use mixed warm water.
As shown in Figure 8, when mixed tank 171 overlaps the area increase with hot water inlet 161, mixing tank 171 reduces simultaneously with the area that cooling water inlet 162 overlaps, flow into the hot water that mixes tank 171 by hot water inlet 161 like this and will become many, flow into the cold water that mixes tank 171 by cooling water inlet 162 and reduce gradually, so mixed water comparative heat.Simultaneously, the area that overlaps of cooling water inlet 162 and cold rinse bank 172 increases, and promptly flows into the cold water that cold rinse banks 172, cooling water outlet 163 enter water tank 8 by cooling water inlet 162 and increases.The water yield that flows into water tank like this is suitable with the water yield that flows out water tank, so keep constant voltage in the water tank, can not increase the hydraulic pressure in the water tank because of injecting cold water.
In like manner, as shown in Figure 9, when 171 of mixed tanks overlap with hot water inlet 161, separate between cooling water inlet 162 and the mixed tank 171.What at this moment, water nozzle 5 flowed out is not pass through the hot water that mixes.At this moment, 162 of cooling water inlets are communicated with cold rinse bank 172, cooling water outlet 163, enter the cold water that mixes water valve 1 and all flow into water tank 8.
On the contrary, as shown in figure 10, when 171 of mixed tanks overlap with cooling water inlet 162, separate between hot water inlet 161 and the mixed tank 171.Enter this moment mix water valve cold water directly by cooling water inlet 162, mix tank 171 to water nozzle 5, the water nozzle place is the cold water through mixing not.This moment, cooling water inlet 162 staggered with cold rinse bank 172, and cooling water inlet can't be communicated with cooling water outlet, does not enter water tank so there is cold water.
In sum, make the cold and hot degree of water, decide with the size that hot water inlet 161, cooling water inlet 162 overlap area by mixed tank 171.The adjustment of described coincidence area size is that the rotation by rotor realizes.Can drive the rotor rotation by operating mixed water valve handle.
