Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of LNG that energy automatic mechanical type turns off the switch
Intelligent safety valve, including intelligent and safe valve chest 1, battery case 3, pcb board 6 and either-rotation motor 7, the intelligent and safe valve chest 1
Upper end screw connection battery case 3 and either-rotation motor 7, the 7 upper end screw connection pcb board 6 of either-rotation motor, the pcb board 6 one
End surfaces are provided with capacitor 4, and the intelligent and safe valve chest 1 is internally provided with screw rod 8, seal cap 9 and transmission gear 5, described
Screw rod 8 is between transmission gear 5 and 8 one end of screw rod engages connection with transmission gear 5, and 8 other end of screw rod is located at sealing
Right above 9 inside of cap and top is just contacted with 9 inner wall center of seal cap, the 7 output shaft outer wall surface of either-rotation motor
It is provided with clutch structure 10, the clutch structure 10 is by clutch tooth wheel seat 11, clutch axis 12 and 13 groups of clutch positioning bead
At.
Further, the either-rotation motor 7 is located at 3 side of battery case, and the battery case 3 is internally provided with battery.
Further, electric wire connects between the either-rotation motor 7, pcb board 6 and battery case 3.
Further, the seal cap 9 is in the form of " U " shape and end surface is provided with " folding trace " and by " folding trace "
It is flexible.
Further, the clutch axis 12 is located at 11 center upper end of clutch tooth wheel seat, the clutch positioning bead 13
Positioned at 12 inside of clutch axis and clutch positioning bead 13 is provided with two groups, any inner wall opposite sides wall surface of the clutch axis 12
