Particularly, at housing 100 axially, edge is from water intake 110 to the direction of water outlet 120, pressure-sensitive assembly 400, Flow-rate adjustment assembly 200 and the temperature module 300 are arranged in order, flow feedback assembly 500 between pressure-sensitive assembly 400 and water intake 110, or between the temperature module 300 and water outlet 120.
Alternatively, the two ends of housing 100 can adopt screw thread, jump ring, clip, and the Placements such as latch are connected with other pipelines.
Here be with it will be appreciated by those skilled in the art that, pressure-sensitive assembly 400 and flow feedback assembly 500 are selectable unit (SU), in other words, flow regulator 60 can not comprise pressure-sensitive assembly 400 and flow feedback assembly 500, also can comprise at least one in pressure-sensitive assembly 400 and flow feedback assembly 500.
The working procedure of the gas water-heater 1 according to the embodiment of the present invention is described below.
As shown in figs 1 to 6, when uniform temperature feed water flow inflow-rate of water turbine controlling device 60, temperature sensibility 330 perception water inlet temperature and linear expansion or contraction change, thus promote moving sleeve 320 move.Moving sleeve 320 drives mobile post 220 to move, and changes the position of tapered portion 221 in cone shape hole, thus changes the aperture of temperature flow adjustment hole 230, and then changes the size of water flow.When intake pressure increases, pressure-sensitive part 420 deformation, changes the gap between itself and mobile post 220, thus changes the cross-section area of pressure flow adjustment hole 430, and then plays the effect of current stabilization.Current are when turbine blade 510, and water flow rotary promotes magnet rotor 520 and rotates, and the rotation of Hall element 530 induced magnetism rotor 520, judges that the size of water flow feeds back to control system 70.Control system 70 regulates the water flow size after feedback according to flow regulator 60, controls the gas supply ratio of gas control system 50, thus the combustion load of control combustion system 40, make water outlet reach ideal temperature.
According to the flow regulator 60 of the embodiment of the present invention, can according to the linear expansion characteristic of temperature sensibility 330, control flow of inlet water and become certain function proportionate relationship with entering water temp, and when intake pressure exceedes setting pressure, no matter entering water temp height, can reach desirable water-exit temperature.Thus, go out temperature constant, fluctuate little, when multiple spot water, hydraulic pressure are excessive, stability of flow.Compared with step motor type water Proportional valve, owing to not needing judgement repeatedly and the calculating of controller, highly shortened the reaction time.Stablized by the shape control flow of inlet water of pressure-sensitive part 420, thus reach the effect of current stabilization, from source, automatically control flow of inlet water, and do not need just to carry out water flow adjustment according to use rear end feedback, the water flow after adjustment can be fed back simultaneously.
