Detailed description of the invention
Under normal conditions, memory alloy spring (7) is in pressured state, down promote magnetic ring component (4) to drive core assembly (5) to move down by magnetic force, block relief hole (12), close auxiliary-valve, till auxiliary-valve not flowing water, meanwhile magnetic ring component (4) drives connecting cylinder (10) to move down, produce relative motion with actionless handle (11), make screw (8) press down spring base (9) and make memory alloy spring (7) be in pressured state.
Now, water feeding pressure is by the main valve on main film formula piston (18) presses hole (21) to enter into the top of main film formula piston (18), due to the parts be connected with main valve joint (17), the auxiliary valve body (1) and the hand stop valve (22) that comprise temperature-controlled member are closed condition, cannot be discharged by the pressure of main valve being pressed hole (21) enter, main film formula piston (18) top is caused to form larger pressure, make main film formula piston (18) downward sedimentation under the effect of pressure reduction, make the anhydrous outflow of main delivery port of main valve body (15), main valve body (15) is in closed condition, system does not work.
When the memory alloy spring (7) at one measuring point place experience environment temperature reach the operating temperature of setting time, memory alloy spring (7) extends instantaneously, screw (8) is with on the bucket (10) that is dynamically connected and is moved, impel magnetic ring component (4) to drive on core assembly (5) to move, open relief hole (12), auxiliary-valve is opened simultaneously, the delivery port water outlet of auxiliary valve body (1), cause the upper pressure of main film formula piston (18) to release simultaneously, the pressure of the influent pressure of main valve body (15) to the bottom of main film formula piston (18) is made to be greater than the upper pressure of main film formula piston (18), under the promotion of intake pressure, main film formula piston (18) moves up and opens the delivery port of main valve body (15), now, main valve body (15) is in opening state, system has at least plural shower nozzle to work at each measuring point place simultaneously.
Once unexpected, when self-winding parts lost efficacy, opened hand stop valve (22), and caused the current of the upper pressure of the main film formula piston (18) of main valve body (15) to discharge through hand stop valve (22), the water inlet of main valve body (15) promotes main film formula piston (18) moves, system works.
When normally using, if when not wishing the spray controlled in a big way, as long as hand stop valve (22) is changed into connection water source, making its former drainage pressure function become supercharging, just only can form point to point operation to the position that auxiliary-valve controls.
