Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 1 is the sectional view of the valve of internally-driven magneto-resistive electromotor driving of the present invention.
On the valve main valve body 1 that internally-driven magneto-resistive electromotor drives water intake 3 and water outlet 4 are arranged, fluid is flowed into by water intake 3, flow out by water outlet 4, there is circular valve port 2 at the partitioning wall middle part that in main valve body 1 water intake 3 and water outlet 4 is separated, internally-driven magneto-resistive electromotor is installed in circular valve port 2 tops, internally-driven magneto-resistive electromotor comprises motor field frame 5, stator 6, rotor 7, tapped through hole is arranged in the middle of the rotor shaft 8, the spool 9 of valve is housed in the through hole, spool 9 is an elongated rod shape, spool 9 one ends are the external thread rod that is arranged in rotor shaft through hole internal thread, internal thread in the outside thread of spool 9 and rotor shaft 8 intermediate throughholes is a trapezoidal thread, it is external that spool 9 the other ends stretch out motor case, and the spool serum cap 12 that the end is a circular flat is housed, and spool serum cap 12 is positioned at the top of valve port 2 upper plane, the cross section at shaft-like spool 9 middle parts is a polygonal, the polygonal cross-section at spool middle part can be a quadrilateral, pentagon, Hexagon, Octagon is quadrilateral among the figure.The polygonal cross-section place is equipped with the spool spline ring 10 of band polygonal hole, polygonal cross-section in the mode of execution is a quadrilateral, spool spline ring 10 is fixed on the internally-driven magneto-resistive electromotor housing 5, the seal ring 11 of the escape of liquid of preventing is arranged between spool 9 and the motor field frame 5, and rotor shaft 8 is bearing on the bearing 13.
