Claims

[Claims for Utility Model Registration] (1) A valve that is opened and closed by rotating its operating shaft approximately 90 degrees, and the operating shaft that is installed in the shaft chamber formed in the body of the valve has one end connected to the valve body. It consists of a stem that is non-rotatably connected to the other end of the stem, and a connector that has one end connected to the other end of the stem so as to be non-rotatable and slidable in the axial direction of the operating shaft, and the other end fixed to the handle. The connector includes a sliding guide part for sliding the connector in the axial direction and rotational direction along the inner wall surface of the shaft chamber, and a wing-shaped part extending right or left or both at right angles to the axial direction. a connector locking portion, a coil spring is installed between the connector and the bottom of the valve chamber, and a locking plate is fixed within the valve chamber by being positioned on the handle side of the connector locking portion. , the side of the locking plate facing the connector locking portion has a sliding plane on which the connector locking portion slides in the rotational direction, and a sliding plane on which the connector locking portion slides in the rotational direction, and a rotation of the connector within a range of approximately 90 degrees for opening and closing the valve. A locking plate locking portion is formed on the sliding surface of the locking plate, and the connector is pushed up by the elastic force of the coil spring when the valve body of the valve is in the closed position. The valve is characterized in that a fitting portion is formed into which the connector locking portion is fitted. (2) The valve according to claim 1, wherein the valve is a ball valve. (3) The valve according to claim 1 of the utility model registration claim, in which the stem and the valve body are integrally provided. (4) The connection between the connector and the stem is parallel to the
The valve according to any one of claims 1 to 3, which is a concave-convex connection with a flat surface. (5) The valve according to claims 1 to 4, wherein the connection between the handle and the connector is a concave-convex connection with two parallel planes. (6) Utility model registration claims 1 to 5, which seal between the stem and the body with an O-ring
Valves listed in section. (7) The locking plate has a disc shape that fits into the shaft chamber, and has a protrusion projecting outward on its outer periphery, and the protrusion is inserted into a groove vertically formed in the peripheral wall of the shaft chamber. The locking plate is fixed to the valve chamber by fitting a locking shaft into a circumferential groove formed on the inner wall surface of the valve chamber. valve.
