磁安全弁装置。[Claims for Utility Model Registration] 1. A lever 2 that is swingable around an intermediate fulcrum 1 is arranged with one end 2a facing an operating rod 3 that moves forward and backward, and the other end 2b is placed in a pressing portion 5a of an electromagnetic safety valve 5. The electromagnetic safety valve 5 is arranged facing each other and is configured to swing the lever 2 by pressing the operating rod 3 to open the electromagnetic safety valve 5.
A line A passing through the fulcrum 1 of the lever 2 and perpendicular to the opening/closing direction of the lever 2 is a line segment D connecting the fulcrum 1 and a contact point B between the pressing portion 5a and the other end 2b when the valve is opened, and the end of the valve opening. When the contact point C between the pressing part 5a and the other end 2b and the fulcrum 1
An electromagnetic safety valve device characterized in that the bisector line substantially equally divides the angle θ formed by the line segment E connecting the lines. 2. A lever 2 that can freely swing around an intermediate fulcrum 1 is arranged with one end 2a facing the operating rod 3 that moves forward and backward, and the other end 2b facing the pressing part 5a of the electromagnetic safety valve 5, In the device in which the electromagnetic safety valve 5 is opened by swinging the lever 2 by a pressing operation, the electromagnetic safety valve 5
An electromagnetic safety valve device characterized in that the other end 2b presses the center of the electromagnetic safety valve 5 at the end of the valve opening. 3 A lever 2 that is swingable about an intermediate fulcrum 1 is arranged with one end 2a facing the operating rod 3 that moves forward and backward, and the other end 2b facing the pressing part 5a of the electromagnetic safety valve 5, In the device in which the electromagnetic safety valve 5 is opened by swinging the lever 2 by a pressing operation, the electromagnetic safety valve 5
A line A passing through the fulcrum 1 of the lever 2 perpendicular to the opening/closing direction of the lever 2 is a line segment D connecting the fulcrum 1 and a contact point B between the pressing portion 5a and the other end 2b when the valve is closed, and the end of the valve opening. When the contact point C between the pressing part 5a and the other end 2b and the fulcrum 1
The other end 2b of the electromagnetic safety valve 5 is made to be a bisector that substantially equally divides the angle θ formed by the line segment E connecting the electromagnetic safety valve 5.
An electromagnetic safety valve device characterized in that the center of the valve is pressed.
