MANUAL VALVE APPARATUS INCLUDING LOCKING MEANS

摘要

A manual valve apparatus including a locking unit is provided to keep a final installation state of a valve at a handle part and visually and easily detect an arbitrary operation by breaking a transparent cap when the handle is forcibly rotated. A manual valve apparatus(100) including a locking unit includes a handle part, and a valve lower body. The locking unit prevents the rotation of the handle. The handle part rotates to open and close a diaphragm of the manual valve. An uneven part is formed at the handle part. The valve lower body forms an oil passage by receiving the diaphragm at an inside thereof. A plurality of projections are formed on a surface of the valve lower body contacted with the valve lower body. The locking unit for preventing handle rotation is inserted between a plurality of projections formed at an upper portion of the valve lower body and a concave portion of the uneven part formed at a lower portion of the handle part. The locking unit for preventing handle rotation fixes the handle part not to be rotated.
