る、 ガス過流出防止機構付ボール弁。[Scope of Claim for Utility Model Registration] A ball with a through hole is airtightly and rotatably installed in a valve chamber of a valve body equipped with a through hole for connecting to gas piping, cylinders, appliances, etc. through a seat. In a ball valve with an existing configuration in which the ball is rotated at a set angle by a spindle connected to the handle to open and close the valve, an overflow prevention mechanism is installed in the input side through hole with the ball as the center. A fuse chamber is formed, a fuse ball is housed in the chamber so as to be freely rotatable, and a valve seat for the fuse ball is formed between the fuse chamber and the valve chamber, and the fuse ball adheres to the valve seat due to excessive gas outflow. The fuse ball is provided so that a part of the fuse ball protrudes into the valve chamber when gas outflow is blocked, and
A ball valve with a gas overflow prevention mechanism, characterized in that a part of the ball collides with a protruding part of a fuse ball when the ball rotates to close the valve, and the fuse ball is forcibly removed from the valve seat. .
