Become.Wherein, water proportioning valve valve body in addition to proportion adjustment flow component itself, a most incidentally discharge
Sensor cluster and temperature sensor assembly.Water proportioning valve is generally seated in water feeding of heater end, can realize regulation
The function of discharge.
When water is by water flow sensor, Hall element can export its frequency with discharge change
The pulse signal of change, feeds back to controller.Water heater controller is according to leaving water temperature and design temperature simultaneously
Between difference to water proportioning valve motor export corresponding control signal, with control water proportioning valve output suitable
Discharge, thus it is rapidly achieved the purpose of design temperature.
Water inlet one end of water proportioning valve is connected with the water supply connector of water heater, outlet one end and heat exchanger
Water inlet link together.When discharge at gas heater needs to adjust, the control of gas heater
Plate can give the regulation signal of motor on water outlet proportioning valve, and motor rotates the valve driven on water proportioning valve
Bar moves, and the aperture further realizing adjusting water proportioning valve water inlet carrys out regulating water flow size.
The water proportioning valve used in the market, often occurs that in user family water proportioning valve discharge regulates not
Situation accurately.Occur that the reason of this problem is to rotate identical step number, in same discharge at motor
In the case of, the outlet discharge of water proportioning valve goes journey and backhaul to there is bigger difference.
The journey of going of water proportioning valve refers to, motor is adjusted to the process of minimum discharge from maximum stream flow.
The backhaul of water proportioning valve refers to, motor is adjusted to the process of maximum stream flow from minimum discharge.
