Description

High sensitivity water flow sensing unit
Technical field
The utility model relates to a kind of separate water flow sensor.
Background technique
Roof is arranged on because present floor uprises solar water heater, because roof area is not enough, so there is human hair to understand, solar water heater is arranged on outside balcony exterior wall, water tank is arranged in balcony but to do discharge pressure so inadequate, has again human hair to understand pressure-bearing type separated solar water heater.
Pressure-bearing type separated solar water heater has two shortcomings: 1, thermal efficiency ratio non-pressure-bearing type solar water heater is low by more than 10%, because water heating needs volumetric expansion, and the feature of pressure-bearing has held the pressure of tap water, the volumetric expansion that water temperature will increase band is suppressed, do manual work because solar temperature rising will overcome pressure, so pressure-bearing is lower by more than 10% than the non-pressure-bearing type solar water heater thermal efficiency; 2, the working method of pressure-bearing type solar water heater be cold water enter hot water could out, when hot water, to use a half just not hot, so not energy saving.
Good solar water heater roof area is inadequate, is pressure-bearing type Split system bad again what if? first determine that Split non-pressurized solar water heater is good product, when unique shortcoming uses water exactly, pressure is little, addressing this problem is exactly good product, can benefit a lot of user.
Someone has used the booster water pump carrying water flow sensing unit, but because the minimum requirements of driving switch water pressure, be one meter high, be not also able to give the height differential water pressures of a meter even if Split non-pressurized solar water heater water tank is arranged on indoor highest point, so cause booster water pump not initiate self.
In view of the above-mentioned defect of prior art, need to adopt a kind of novel solar water heater controller, key is novel highly sensitive water flow sensing unit, can solve Split non-pressurized solar water heater recloser suction booster problem.
model utility object
The purpose of this utility model is to provide a kind of novel highly sensitive water flow sensing unit, and this switch designs is ingenious, and structure is simple, highly sensitive, applied widely.
The purpose of this utility model is achieved through the following technical solutions, high sensitivity water flow sensing unit, comprise housing, enclosure interior hollow forms water channel, mounting plate is provided with in housing, current sealing plate, the Magnetosensing element cooperatively interacted and magnet, mounting plate and described inner walls are sealed and matched, mounting plate is provided with via hole, current sealing plate is hinged on described mounting plate, described magnet is arranged on current sealing plate, described Magnetosensing element is arranged on housing, when non-water flow flows through via hole, under the interaction of Magnetosensing element and magnet, described mounting plate is close to by current sealing plate, cross bore closure, when there being current to flow through via hole, current sealing plate leaves described mounting plate, via hole is opened.
Preferably, described via hole is positioned at described mounting plate center.
Preferably, described via diameter is 6-20mm.
Preferably, described current sealing plate top is square, and bottom is arc.
Preferably, described Magnetosensing element is by wire connection control element or controller.
Preferably, described housing is provided with installation cover.
Preferably, described current sealing plate is sheet metal or non-metal board.
Preferably, described housing is metal shell or non-metal shell.
Compared with prior art, the utility model has following beneficial effect:
First, highly sensitive water flow sensing unit, comprise: wire, Magnetosensing element, current sealing plate, magnet, via hole, water channel, connecting pin, when current are by meeting jack-up current sealing plate during via hole, and magnet on current sealing plate also can jack-up thereupon, then magnet reduces along with distance increasing magnetic field, and Magnetosensing element just has different signals to pass to controller by wire, controller judges streamflow regime and switching value according to signal, makes corresponding action.
Second, the size of via hole and current sealing plate the sensitivity of weight and water flow sensing unit have relation, when via hole is larger, the more heavy then high sensitivity of current sealing plate is lower, both are proportionate relationships, the water pipe via diameter of ordinary circumstance G1/2 inch should not be greater than 12MM, and the differential water pressures that 15CM is high as via diameter 10MM just can normally work.If reduce via diameter again or reduce current sealing plates weight can improve the sensitivity of water flow sensing unit further.
3rd, the water flow sensing unit of new type of high sensitivity can be used for electric water heater, gas water-heater, non-pressure-bearing type solar water heater, also can increase the direct automatically controlled water pump of peripheral circuit.
