Specific embodiment
Under normal conditions, memory alloy spring(7)In pressured state, magnetic ring component is down promoted(4)To drive core assembly by magnetic force(5)Move down, block relief hole(12), close auxiliary-valve, till auxiliary-valve not flowing water, at the same time magnetic ring component(4)Drive connecting cylinder(10)Move down, with actionless handle(11)Relative motion is produced, screw is made(8)Push spring base(9)Make memory alloy spring(7)In pressured state.
Now, water feeding pressure passes through main film formula piston(18)On main valve on press hole(21)Enter into main film formula piston(18)Top, due to main valve joint(17)The part of connection, including the auxiliary valve body of temperature-controlled member(1)And hand stop valve(22)Closed mode is, by hole being pressed on main valve(21)Into pressure cannot discharge, cause main film formula piston(18)Larger pressure is formed at top, makes main film formula piston(18)Settled in the presence of pressure reduction downwards, make main valve body(15)The anhydrous outflow of main delivery port, main valve body(15)It is closed, system does not work.
Memory alloy spring at one measuring point(7)When experiencing environment temperature and reaching the operating temperature of setting, memory alloy spring(7)Moment extends, screw(8)Drive connection bucket(10)Upper shifting, promotes magnetic ring component(4)Drive core assembly(5)Upper shifting, opens relief hole(12), auxiliary-valve is while open, auxiliary valve body(1)Delivery port water outlet, while causing main film formula piston(18)Upper pressure release so that main valve body(15)Influent pressure to main film formula piston(18)Bottom pressure be more than main film formula piston(18)Upper pressure, under the promotion of intake pressure, main film formula piston(18)Move up and open main valve body(15)Delivery port, now, main valve body(15)In opening state, system has at least two shower nozzle can be while working at each measuring point.
Once it is unexpected, when self-winding parts fail, open hand stop valve(22), cause main valve body(15)Main film formula piston(18)The current of upper pressure handle dynamic stop valve(22)Discharge, main valve body(15)Water inlet promote main film formula piston(18)Upper shifting, system work.
In normal use, it is undesirable that when controlling large range of spray, as long as hand stop valve(22)It is changed to connect water source so as to which former drainage pressure function becomes supercharging, it is possible to which the position for only controlling auxiliary-valve forms point to point operation.
