Abstract
Official abstract text for this publication.
A regulating valve includes a valve body having a cylindrical portion, a valve stem, and a locking member. The valve body includes a female screw formed on the inner wall of the cylindrical portion and at least one chamfered portion formed on the outer wall of the cylindrical portion. The valve stem includes a first male screw and a second male screw formed on the surface close to the other end of the valve stem. The locking member includes a nut corresponding to the second male screw and a tongue portion formed integrally with the nut, extends in a direction orthogonal to an axial line S from one end portion of the nut, and is bendable in the direction parallel to the axial line.
First claim
Opening claim text (preview).
The invention claimed is: 1. A locking member for preventing engagement between a valve body and a valve stem of a regulating valve from being loosened, the locking member comprising: a nut on which threads are formed; and a tongue portion formed integrally with the nut at a coupling surface so as to extend in a direction orthogonal to an axial line of the nut from one end portion of the nut, the tongue portion being a ring having a continuous circular outer edge and being bendable in a direction parallel to the axial line, wherein the tongue portion has plasticity in a vicinity of the coupling surface with the nut and is bendable in the direction of the axial line using the coupling surface as a fulcrum.
