Claims

[Scope of claim for utility model registration] Inside the valve chamber of the valve body, which is equipped with a through hole that connects to the pipeline,
A ball valve with an existing configuration in which a ball with a through hole is airtightly and rotatably housed through a seat, and the ball is rotated at a set angle by a spindle connected to a handle to open and close the valve. In this case, a concave and convex connection part with the handle is provided on the top surface of the short cylindrical body.
A spindle with a concave-convex connection with the stem on its lower surface and a guide protrusion on a part of its circumference, and a spindle with a guide slit consisting of a vertical part and a horizontal part cut into a short cylindrical body with a short inner diameter into which the spindle fits. A ball with a stem is provided in which the ball is integrally formed with a stem that has a guide and a concave-convex connecting portion that fits and connects with the concave-convex connecting portion on the lower surface of the spindle, and is installed in a fitting cylinder portion that extends integrally above the valve chamber of the valve body. , insert the above three parts in the order of the ball with stem, the spindle guide, and the spindle, insert the spindle into the spindle guide, engage the guide protrusion with the vertical part of the guide slit, and spring the spring between the spindle and the spindle guide. In addition, the concave and convex connecting portions of the spindle and the stem are fitted and connected, and this installed state is supported by appropriate means, and the concave and convex connecting portion of the upper surface of the spindle installed in the fitting cylinder portion and the appropriate lower surface of the handle are installed. A ball valve constructed by fitting and connecting concave and convex connecting parts.
