Background technology
1, present, China's immediately heating water heater (comprising two kinds of electrothermal and combustion types) causes that as the hydraulic pressure instability discharge instability causes the unsettled phenomenon of leaving water temperature because of no flow controller.Low when high during water temperature, use very inconvenient.
2, present, the firing system major part of China's gas heater is mechanical firing system: promptly promote the aqueous vapor gangbar and promote microswitch and light a fire with hydraulic pressure, in case hydraulic pressure is not enough, can't promote microswitch then water heater can't use.Mechanical firing system complex structure, volume are big, and be unstable, be not durable.
3, present, China's gas heater all is to control firepower by the size that manual (mechanical type) knob is regulated gas quantity, and then regulates water temperature, in case the hydraulic pressure instability causes the unsettled phenomenon of leaving water temperature.It is low when high during water temperature that to dash cold very not well.
Summary of the invention
At the technical deficiency of above existence, the purpose of this utility model is to provide a kind of discharge inductor of automatic control water yield size.
Goal of the invention of the present utility model is achieved by the following technical solution:
The discharge inductor comprises hall sensor component, valve body, water conservancy diversion cover, Magnmet rotor assembly, air deflector, flow controller, fixed screw, water delivering orifice, water inlet, and hall sensor component comprises PCB, Connection Block, Hall element; The magnet rotor assembly comprises the magnet and the stainless steel rotating shaft of turbine-like, described PCB, Hall element, resistance, electric capacity epoxy sealing, Magnmet rotor assembly adapter sleeve is in water conservancy diversion cover and air deflector, air deflector connects flow controller, the proportionate relationship of regulating impulse frequency and discharge is installed into valve body to above assembly again.At last hall sensor component is fixed on the valve body with fixed screw.The direct current of 5V on Connection Block 13 is logical, when magnet rotated, Connection Block 13 has 5V, and (pulse of electric current＜10mA) was exported.
1, the utility model utilizes the magnetoelectricity transfer principle, water drives magnet rotor (the two poles of the earth magnet) rotation once flowing, the magnet that rotates quite produces the rotating magnetic field of different magnetic poles, and the Hall element cutting magnetic induction is answered line, and the Hall element that is in the magnet top then produces the height impulse level.Because the output pulse signal frequency of Hall element is directly proportional with the rotating speed of magnet rotor, the rotating speed of rotor is directly proportional with discharge again, the high more current of hydraulic pressure are fast more, the magnet rotor velocity of rotation is just fast more, the pulsed frequency of output is just high more, and microcomputer chip is connected dynamoelectric water valve more automatically with the discharge that presets (such as 10L/Min) and carried out the valve size adjusting according to the size of the size judgement discharge of this pulsed frequency, reach the constant purpose of discharge, constant to guarantee water temperature.
2, at gas heater, as long as water flows through valve body, the very low magnet of that water funk pressure all can rotate, and magnet rotates Hall element and just has pulse output.Microcomputer chip has detected pulse output and has then connected ignition switch and electromagnetic gas valve automatically, reaches the purpose of low hydraulic pressure starting.
When 3, Dang Shui flows through the magnet rotor assembly, Hall element is exported corresponding pulse signal and is fed back to microcomputer chip, judge the size of discharge by microcomputer chip, when hydraulic pressure is unstable, can cause the variation of discharge and then cause the variation of water temperature, microcomputer chip can be regulated the electric current of control ratio valve automatically, thereby passing ratio valve control combustion gas tolerance reaches the constant purpose of water temperature.
The utlity model has simple in structure, reliable operation, metering accurately, advantage such as response is fast, durable, inexpensive.
