Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figures 1 to 3, the bistable state selector valve of controlling with the two contacts of the interconnected reset of spring of the present invention, comprise valve body 1 and two levers 2, roller 3 is equipped with at lever 2 tops, two lever 2 middle parts are articulated with valve body 1 by bearing pin 4, between two levers 2 of valve body 1 outside, be connected with spring 5, valve body 1 is established rod chamber 6, in bar chamber 6, be provided with valve rod 7, valve rod 7 can be in the interior slip in bar chamber 6, valve body 1 is provided with end cap 8 in lever 2 both sides, end cap 8 is affixed by screw 9 and valve body 1, corresponding lever 2 bottoms, valve rod 7 two ends, valve rod 7 two ends are provided with push shaft 10 and O-ring seals 11, the interior corresponding valve rod 7 in bar chamber 6 is provided with guide pin bushing 12, valve rod 7 middle parts are provided with seal ring 13, consult Fig. 4, valve rod 7 is provided with first body of rod 14 in seal ring 13 both sides, the first body of rod 14 diameters are less than the diameter of seal ring 13 and stem valve, first body of rod 14 and bar chamber 6 form gas channel 15, valve body 1 is provided with air source hole 16 and two delivery outlets 17, air source hole 16 is positioned at 6 tops, bar chamber, and be communicated with bar chamber 6, delivery outlet 17 is positioned at 6 belows, bar chamber, and be communicated with bar chamber 6.
