Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-5 is please referred to, the present invention provides a kind of technical solution: a kind of LNG intelligence that energy automatic mechanical type turns off the switch
Safety valve, including intelligent and safe valve chest 1, battery case 3, pcb board 6 and either-rotation motor 7,1 upper end of intelligent and safe valve chest
Screw connection battery case 3 and either-rotation motor 7, the 7 upper end screw connection pcb board 6 of either-rotation motor, 6 one end table of pcb board
Face is 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, the screw rod 8
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 in seal cap 9
Right above portion and top is just contacted with 9 inner wall center of seal cap, and the 7 output shaft outer wall surface of either-rotation motor is provided with
Clutch structure 10, the clutch structure 10 are made of clutch tooth wheel seat 11, clutch axis 12 and clutch positioning bead 13.
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 two lateral walls of the clutch axis 12
Face is thicker, the clutch tooth wheel seat 11 shape in the shape of a " convex ".
Further, 7 output shaft of either-rotation motor is nibbled through 1 end surface of intelligent and safe valve chest and transmission gear 5
Close connection.
Specifically, when natural gas leaking occurs, passing through pcb board 6 after being manually packed into battery in battery case 3
Pre-set operation program connects 7 power supply of either-rotation motor, drives transmission gear 5 to rotate using either-rotation motor 7, and lead to
Crossing the transmission of transmission gear 5 makes screw rod 8 follow rotation, and by after the ejection of seal cap 9, gas transmission official jargon is blocked, to reach automatic machine
Tool obstructs the function of gas passage, effectively prevents natural-gas leakage, while saving use cost, effectively avoids
Because natural gas leaking is more, the case where causing fire, safety when use is effectively raised, when in clutch axis 12
When clutch positioning bead 13 turns to 12 inner wall of clutch axis thicker position (Fig. 4 dash area), 13 ball part of clutch positioning bead
After retraction makes clutch positioning bead 13 and the 12 inner wall increased friction of clutch axis, to drive clutch tooth wheel seat 11 while rotate, when from
Close (Fig. 4 dash area) when positioning bead 13 rotates out 12 inner wall of clutch axis thicker position, clutch positioning bead 13 and clutch axis
Frictional force becomes smaller between 12, forms idle running, can play good protecting effect, and the length for preventing screw rod 8 from extending is too long, is more than
While the limit of 9 tension of seal cap causes seal cap 9 to be damaged, the loss between whole drive mechanism is effectively avoided, is mentioned
High service life.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
