Number feed back to control module., it is necessary to water impact wheel rotation during compared to the structure that impeller and magnet ring are used in conventional art
Magnetic field can be produced, the impulsive force that impeller is subject in the case that current are disorderly is also disorderly, and produced magnetic field is then unstable.And
Rotated in the application by turbine, be to be advanced to be driven to rotate by turbine by current using turbine rotation, and it is indirect
Cause the characteristic of rotation by impulsive force, stability when improving rotation with this so that magnet rotor can produce more stable
Magnetic field, improves stable magnetic field, is easy to the purpose that sensor gathers signal so as to realize.
It is preferred that, the Hall flow sensor is located at valve body lateral wall.Avoid electronic component by water currents, raising makes
Use the life-span.
It is preferred that, the Hall flow sensor is potted in epoxy resin block.It is by the printing with Hall element
Board component integral sealing is in epoxy resin block, it is to avoid electronic component is destroyed by water currents and external force, improves service life.
Further, in addition to positioned at the temperature sensor of valve inner, the temperature sensor and control module is defeated
Enter end to be connected.Control module is compared according to actual temperature with design temperature, so that instruction extremely regulation valve actuator is transmitted, with
This regulation hot and cold water water yield, realizes the function of temperature adjustment.
It is preferred that, the output shaft of the turbine is made by stainless steel material.To improve the intensity of output shaft with using
Life-span, it is to avoid it is by current erosion and corrosion.
It is preferred that, the magnet rotor is made by magnetic plastics material.Magnetic plastics density of material is small, impact strength
Greatly, the miniaturization, lightweight, precise treatment of the utility model structure are conducive to.
It is preferred that, the magnet rotor is integrally formed with output shaft.To improve the stable connection between magnet rotor and output shaft
Property, prevent that magnet rotor comes off under flow action, it is ensured that magnet rotor is rotated with output shaft.
The utility model compared with prior art, has the following advantages and advantages：
The utility model axial-flow type water proportioning valve, is rotated by turbine, is to pass through whirlpool by current using turbine rotation
Wheel advance is driven to rotate, and it is indirect cause the characteristic of rotation by impulsive force, stability when improving rotation with this so that
Magnet rotor can produce more stable magnetic field, improve stable magnetic field so as to realize, be easy to the purpose that sensor gathers signal.
