Claims

[Claims for Utility Model Registration] At least the downstream portion of the main body 2 of the overflow prevention valve is immersed in an inverted L-shaped passage hole formed in the closure 10 in the main body 1, and the valve of the main body 2 is The skirt portion 53 of the valve body 5, which closes the seat opening 20 and is biased in the normally closed direction, is fitted onto the trunk of the main body 2 so as to be able to rise and fall freely, and the skirt portion 53 and the outer periphery of the base end of the main body 2 are arranged. A cam mechanism is interposed between the cam section and the cam section, and this cam mechanism is operated in accordance with the rotation of the closing member 10 to open and close the valve body 5, and also to open and close the valve body 5 at the fully open position of the closing member 10 and the closing member in the vicinity thereof. In a gas tank equipped with an overflow prevention valve configured to maintain the valve body 5 in an open state only in the open position, the closure 10 and the valve body 5 are mated in the axial direction of the two, and the two are integrally rotated. The valve seat opening 20 is constructed from an annular sheet body 23 made of an elastic material.
3 is brought into contact with the lower surface of the valve body 5, and a protrusion M integral with the inner peripheral edge of the seat body 23 is made to protrude inwardly.
A protrusion 59 is formed at a position facing the range surrounded by A gas tank with an overflow prevention valve that matches the protrusion M. At least the downstream portion of the main body 2 of the overflow prevention valve is immersed into an inverted L-shaped passage hole formed in the closure 10 in the Kotuku main body 1, and the valve seat opening 20 of the main body 2 is closed. The skirt portion 53 of the valve body 5, which is biased in the closing direction, is fitted onto the body of the main body 2 so as to be able to rise and fall freely, and between the skirt portion 53 and a cam portion disposed on the outer periphery of the base end of the main body 2. A cam mechanism is installed, and this cam mechanism is operated in accordance with the rotation of the closure 10 to open and close the valve body 5, and to open and close the valve body 5 only when the closure 10 is in the fully open position and in the vicinity of the closure open position. In a gas tank equipped with an overflow prevention valve configured to maintain the valve in an open state, an auxiliary passage H is formed that communicates the side wall of the closure housing part of the gas tank body 1 with the upstream side of the overflow prevention valve housing part. A gas tank equipped with an excessive outflow prevention valve, in which the downstream end of the passage H is opened in the side wall of the closure accommodating part that coincides with the downstream opening end of the passage hole of the closure 10 when the closure 10 is in the fully closed position.
