Combined with specific embodiments below, the present invention is described in detail.

1, fault verification:

1.1, when being switched on, electromagnetism two-port valve, which powers on rear stepper motor and first resets, allows water valve to return to minimum aperture F0, and minimum is opened Degree is the water valve aperture F1 or actuator most initial position F2 when flowmeter detects numerical value 0.

(note: F2 is fixed value)

(1) when flowmeter normal operation, F0=F1

(2) when flowmeter failure, when cannot detect current water flow, F0=F2

(3)F1≤F2

1.2, when running, the maximum opening of electromagnetism two-port valve is Fmax, and maximum opening is that electromagnetism two-port valve detects flow Reach maximum stream flow F3 or actuator maximal end point position F4, stops valve opening after reaching maximum opening Fmax.(note: F4 is to fix Value)

(1) when flowmeter normal operation, Fmax=F3

(2) when flowmeter failure, when cannot detect current water flow, Fmax=F4

(3) F3 < F4

1.3, when electromagnetism two-port valve opens to the maximum aperture Fmax, if flow detector detects that flow F5 is less than maximum at this time Flow F3 70% when, i.e., report the dirty stifled failure of water route fouling.

2, valve opening controls:

2.1, water valve is according to target temperature opening and closing, from target temperature further away from, water valve aperture regulation frequency is faster, By opening gap that is big or turning down water valve shortening and target temperature；On the contrary closer from target temperature, water valve aperture regulation frequency is got over It is small, pass through water valve holding and target temperature.

2.2, an electric two-way valve is set after water valve, has a slide plate to control water flow on electric two-way valve, has simultaneously Two detection switch.

2.3, it is electronic when slide plate is adjusted to maximum opening when slide plate is up adjusted with the aperture increasing of water valve The detection switch 1 of two-port valve disconnects, and is denoted as ON, and electric two-way valve slide plate is no longer opened greatly at this time, and water valve stops adjusting aperture (at this time For safe maximum opening).

2.4, it is electronic when slide plate is adjusted to minimum aperture when slide plate is adjusted down with the aperture reduction of water valve The detection switch 2 of two-port valve disconnects, and is denoted as OFF, and electric two-way valve slide plate is no longer turned down at this time, and water valve phase down acts (this When for the minimum aperture of safety).

2.5, in general hot water machine, tap water enters heat pump heat exchanger by water valve, by the heating of heat pump system Afterwards, it is stored into water storage box.When the temperature difference between the target temperature that the temperature of tap water and system are arranged is larger, system adjusts water The frequency of valve regulation increases the adjusting frequency to water valve aperture, so that the leaving water temperature of heat pump system is rapidly achieved target temperature. System judgement is when needing out big water valve, and when the aperture of water valve is not turned off greatly to the maximum opening of electromagnetism two-port valve slide plate, detection is opened It closes 1 to disconnect, water flow is intake with flow at this time toward heat pump system.Conversely, water valve is opened when system judgement needs to turn down water valve Constantly when being decreased to the minimum aperture of electromagnetism two-port valve slide plate, detection switch 2 disconnects degree, and water flow is with flow at this time toward heat pump system System water inlet.

Technical solution of the present invention lowers the impaired probability of valve body, extends the service life of valve body by duplicate protection.Increase Water route fouling dirty stifled fault mechanism can detect the fouling condition in water route, handle in time, avoid the damage of component.
