This article is a fluid control valve; as shown in the reference perspective view, the article includes a hood, a valve main body, and a hollow cylindrical part provided between the hood and the valve main body; as shown in the reference cross-sectional view, the cylindrical part is characterized by having a width greater than that of the stem and sufficient to allow a valve element, such as a ball, to be inserted into the cylindrical part and by having a length sufficient to prevent an operating part from freezing due to refrigeration by the fluid; the cylindrical part, including welding parts, is the portion for which a design registration is sought; the welding parts shown in the reference perspective view are joint structures adaptable to application to liquefied hydrogen, and it is possible to form the cylindrical part without the welding parts; the solid lines indicate the portion for which a design registration is sought; the thin lines drawn on curved surfaces do not indicate any patterns, but indicate the shape of stereoscopic surfaces; in the reference cross-sectional view, the hatched areas represent cross-sections of the subject article; in the reference cross-sectional view, part of the inner structure of the article is omitted.
