It is divided into two-way after net and water feeding one-way valve and has respectively entered hot water spool and cold water valve core.Beat when hot water handle controls hot water spool
When opening so that tap water enters outlet passage by hot water spool, enters the left inside cavity in hydraulic pressure switch chamber, left cavity afterwards
Internal water by the first through hole and pressure adjustable check valve enter into base interior cavity interior in, the water in base interior is by the
Two through holes enter into right inside cavity, and the water being simultaneously into base interior is discharged outside by Discharging bent-tube.Due in pedestal
Water in portion is exhausted directly to outside therefore the hydraulic pressure of base interior is extremely low, and the hydraulic pressure in right cavity is equal to the water of base interior
Pressure.When connector inside water pressure of intaking is more than 0.03MPa, owing to the aperture of the first through hole is the least, add pressure adjustable list
To the choked flow effect of both valves, the hydraulic pressure in the most left cavity promotes spring more than the hydraulic pressure in right cavity, the pressure differential of generation
Diaphragm moves right, and spring diaphragm drives seesaw push rod to move right together, the end of seesaw push rod under the effect of lever principle

By hot water spool and cold water valve core, now Discharging bent-tube not water outlet.
2, as shown in Figure 4, when cold water handle is not switched on, and hot water handle controls hot water spool and opens so that water inlet connects
The Natural Water of part enters in left cavity by outlet passage, and the water in left cavity passes through the first through hole and pressure adjustable check valve
Entering in pedestal, on the one hand the water in pedestal enter in right cavity by the second through hole, arranges simultaneously also by Discharging bent-tube
To outside.Owing to the water in pedestal is exhausted directly to outside, therefore the hydraulic pressure in pedestal is extremely low, and the hydraulic pressure in right cavity is equal to base
Hydraulic pressure in Zuo.When connector hydraulic pressure of intaking is more than 0.03MPa, owing to the first through-hole aperture is the least, add pressure adjustable
The choked flow effect of both check valves, in the most left cavity, hydraulic pressure promotes spring diaphragm more than hydraulic pressure in right cavity, the pressure differential of generation
The top of sheet is moved to the right.Power conduction to calandria is switched by lever principle by seesaw push rod again, seesaw push rod
The on & off switch that calandria switchs, calandria switch energising work are pressed down in bottom, thus control calandria work.When water inlet connector
When water feeding pressure is less than 0.03MPa, although hydraulic pressure is more than hydraulic pressure in right cavity in left cavity, but the pressure differential produced is insufficient to push away
Dynamic spring diaphragm own resilience and calandria switch making a concerted effort of the feedback force to seesaw push rod.Calandria switchs obstructed electrician
Make.When connector intake pressure of intaking big the most to a certain extent time, pressure adjustable non-return valve operational makes the hydraulic pressure in left cavity let out
Falling a part, protection spring diaphragm is unlikely to stress and crosses Major disruptionL.
3 as it is shown in figure 5, work as hot water handle and be not switched on, and cold water handle controls cold water valve core and opens so that water inlet connects
Natural Water in part enters in pedestal by cold water valve core and pod apertures, and the water in pedestal is discharged outside by Discharging bent-tube.
Owing to hot water spool is not switched on, in the most left cavity, right cavity, pedestal, hydraulic pressure is all equal, thus left cavity and right cavity it
Between can not produce differential water pressures, calandria does not works.Cold water handle only draws oneself up the opening and closing of this road water, is not involved in hot water handle water
Road controls work.
4, as shown in Figure 6, all open when hot water handle and cold water handle so that the Natural Water in water inlet connector is by warm
Water valve core and cold water valve core enter in pedestal, occur blending water state.Owing to the water in pedestal is outside by Discharging bent-tube
Draining, hot water spool is opened so that hydraulic pressure in hydraulic pressure is more than right cavity in left cavity, now calandria work.When Discharging bent-tube goes out
When coolant-temperature gage is higher, when hot water spool water yield cannot regulate applicable water temperature, opening so that Discharging bent-tube goes out of cold water valve core
The water yield strengthens thus carries out lower water temperature.
The above is only preferred implementation of the present utility model, is applicable not only to the electric heating fire hose that double spool controls
Head, is also applied for monolever and controls electric hot water tap.Described monolever control electric hot water tap spool be exactly hot water spool with
Cold water valve core function a kind of made that combines enters three pore structure spools of scene 2, it is noted that lead for this technology
