Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figures 1 to 3, bistable state selector valve with the interconnected two contact controls that reset of spring described in the utility model, comprise valve body 1 and two levers 2, roller 3 is equipped with at lever 2 tops, two lever 2 middle parts are articulated in 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, be provided with valve rod 7 in the bar chamber 6, valve rod 7 can the 6 interior slips in the bar chamber, 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, bar chamber 6 interior corresponding valve rods 7 are 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, first body of rod, 14 diameters are less than the diameter of seal ring 13 and stem valve, and first body of rod 14 and bar chamber 6 form gas channel 15, and 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 is communicated with bar chamber 6.
