In specific embodiments more of the present utility model, as shown in figs 2-4, pressure-sensitive Flow-rate adjustment assembly 300 includes determining
Position seat 310, locating cover 320 and pressure-sensitive part 330.
Positioning seat 310 is provided with the multiple circumferentially-spaced multiple positioning seat vias 311 along positioning seat 310.Locating cover 320 is installed
Positioning seat 310 is and with positioning seat 310 below, it is multiple circumferentially-spaced that locating cover 320 is provided with along locating cover 320
Multiple locating cover vias 321 and stretch into the diversion column 323 of positioning seat via 311.Pressure-sensitive part 330 can according to pressure shape
Becoming, such as, pressure-sensitive part 330 can be rubber ring, and pressure-sensitive part 330 is set on diversion column 323 and is positioned at positioning seat 310
And between locating cover 320, limit between inner peripheral surface and the outer peripheral face of diversion column 323 of pressure-sensitive part 330 respectively with positioning seat
The pressure flow adjustment hole 430 that via 311 connects with locating cover via 321, pressure-sensitive part 330 is regulated by the deformation of self
The cross-sectional area of pressure flow adjustment hole 430.
Specifically, when the hydraulic pressure in water inlet flow channel 130 is higher, water is acted on pressure-sensitive part 330 by locating cover via 321,
Pressure-sensitive part 330 diminishes towards diversion column 323 deformation, the cross-sectional area of pressure flow adjustment hole 430, and then reduces discharge.
When the hydraulic pressure in water inlet flow channel 130 is relatively low, pressure-sensitive part 330 recovers original shape, pressure flow adjustment hole 430
Cross-sectional area becomes big, and then increases discharge.
Those skilled in the art is it will be understood that pressure-sensitive part 330 is looped around the outside of diversion column 323, and pressure flow regulates
Hole 430 is limited by the inner peripheral surface of pressure-sensitive part 330 and the outer peripheral face of stroke sleeve 220, when hydraulic pressure that pressure-sensitive part 330 is subject to is bigger,
Pressure-sensitive part 330 towards diversion column 323 deformation (i.e. pressure-sensitive part 330 is crushed), and then can reduce the horizontal stroke of pressure flow adjustment hole 430
Sectional area.When hydraulic pressure that pressure-sensitive part 330 is subject to is less, pressure-sensitive part 330 recovers shape, and then the horizontal stroke of pressure flow adjustment hole 430
Sectional area increases.
Alternatively, as shown in Figure 3 and Figure 4, what the inner peripheral surface of positioning seat 310 was provided with along positioning seat 310 is circumferentially extending
Assembling annular groove, the outer edge of locating cover 320 coordinates in described assembling annular groove.
In concrete examples more of the present utility model, as shown in Figure 3 and Figure 4, pressure-sensitive Flow-rate adjustment assembly 300 is positioned at stream
Between amount feedback component 400 and water inlet 110, flow feedback assembly 400 is positioned at pressure-sensitive Flow-rate adjustment assembly 300 and water outlet
Between runner 140.Thus can so that pressure-sensitive Flow-rate adjustment assembly 300 more accurately regulates flow according to water feeding pressure,
Current are avoided to first pass through flow feedback assembly 400 and the accuracy of hachure pressure-sensitive Flow-rate adjustment assembly 300 pressure-sensitive.
Wherein, as Figure 1-Figure 4, flow feedback assembly 400 includes mounting seat 410, turbo blade, magnet rotor 430
With Hall element 440.
Described turbo blade is rotatably provided in mounting seat 410.Magnet rotor 430 is rotatably provided in mounting seat 410
And adjacent to described turbo blade.Hall element 440 is arranged on the outer wall of shell 100.
Specifically, turbo blade rotate time drive near water flow rotary, the water jet propulsion magnet rotor 430 of rotation rotates,
Hall element 440 is judged discharge by the rotation of induced magnetism rotor 430 and is utilized control line to feed back to control system 70.
Advantageously, as shown in figs 2-4, mounting seat 410 includes mounting seat 411 and lower mounting seat 412.Upper mounting seat
411 are provided with upper shaft hole and upper discharge orifice 414.Lower mounting seat 412 is removably mounted on the lower end of mounting seat 411, lower peace
Dress seat 412 is provided with lower shaft hole and lower discharge orifice 416.Magnet rotor 430 have central axes upper rotating shaft 431 and under
Rotating shaft 432, upper rotating shaft 431 is rotatably fitted in described upper shaft hole and lower rotary shaft 432 be rotatably fitted to described under
In axis hole, described turbo blade is rotatably installed in lower mounting seat 412.Turbo blade and magnetic thus can be facilitated to turn
The dismounting of son 430.
Further, as shown in figs 2-4, being provided with retainer ring 450 in water inlet flow channel 130, retainer ring 450 is positioned at peace
Below dress seat 410, mounting seat 410 is fixed by retainer ring 450.
The work process of gas heater 1 according to this utility model embodiment is described below.
As Figure 1-Figure 4, when uniform temperature feed water flow inflow-rate of water turbine self-checking device 10, when intake pressure increases,
Pressure-sensitive part 330 deformation, changes the gap between itself and diversion column 323, thus changes the transversal of pressure flow adjustment hole 430
Area, and then play the effect of current stabilization.The temperature of temperature-sensitive bag 330 perception outlet passage 140 and linear expansion or contraction change,
Thus promote stroke sleeve 220 to move, change aperture regulation 222 position in bellmouth, thus change temperature flow
The aperture of adjustment hole 250, and then change the size of discharge.When water flows through turbo blade, water flow rotary promotes magnet rotor
430 rotate, the rotation of Hall element 440 induced magnetism rotor 430, it is judged that the size of discharge feeds back to control system.
Control system supplies according to the discharge size after automatic flow rate adjusting device 10 regulation feedback, the combustion gas controlling gas control system
Answer ratio, thus control the burning load of combustion system, make water outlet reach ideal temperature.
Automatic flow rate adjusting device 10 according to this utility model embodiment, can according to the linear expansion characteristic of temperature-sensitive bag 330,
Control the function proportionate relationship that flow of inlet water becomes certain with inflow temperature, and when intake pressure exceedes setting pressure, no matter
Inflow temperature height, can reach preferable leaving water temperature.Thus, go out temperature constant, fluctuate little, multiple spot use water,
When hydraulic pressure is excessive, stability of flow.Compared with step motor type water proportioning valve, owing to need not judgement repeatedly and the meter of controller
Calculate, highly shortened the response time.Stable by the shape control flow of inlet water of temperature-sensitive bag 330, thus reach current stabilization
Effect, automatically controls flow of inlet water from source, without according to using rear end feedback just to carry out discharge regulation, simultaneously
Discharge after regulation can be fed back, and be easy to the integral arrangement of gas heater inner space.
