Hoop lower half slips and hoop upper half slips are assembled in pair and fastened through two sets of bolts and nuts to form fast detaching structures outside a valve body. According to the adopted technology, the titanium alloy five-blade connecting rib horizontal check valve of a hoop joint comprises a cylindrical shaft, a swing valve element, a hoop joint valve body, fastening screws and outer end covers. The titanium alloy five-blade connecting rib horizontal check valve of the hoop joint is characterized in that the outer end of an outlet elbow and the outer end of an inlet elbow on the hoop joint valve body are respectively provided with a valve pipe plane, a valve pipe frustum face is arranged on the inner side of each valve pipe plane, the ends of external pipeline joints are provided with pipeline planes to be tightly attached to the valve pipe planes, and the inner sides of the pipeline planes of the external pipeline joints are pipeline frustum faces and correspond to the valve pipe frustum faces; the hoop lower half slips and the hoop upper half slips which assembled in pair and fastened through the two sets of bolts and nuts are provided with valve pipe conical hole faces and pipeline conical hole faces to be matched with the valve pipe frustum faces and the pipeline frustum faces; the single-blade thickness of five-blade connecting ribs is 1 / 21 to 1 / 19 of the diameter of a round flow channel opening.

The invention relates to a special valve for an offshore oil drilling platform, and particularly to a copper alloy five-connecting-rib check valve of a flange connector. The check valve comprises a lower flange head hemisphere casing, an upper flange head hemisphere casing, a cylindrical pipe and a variable flow cavity valve core, wherein four sets of valve casing bolts and nuts are sealed, positioned and fixed between a lower four-lug on the lower flange head hemisphere casing and an upper four-lug on the upper flange head hemisphere casing, a deformed flow channel passes through the space between a valve core annular hole in the lower spherical surface of the valve core and a valve core circular hole in the upper spherical surface of the valve core, and five diversion supporting plates are arranged on the deformed flow channel; the inner side surfaces of the five diversion supporting plates are fixedly connected with the valve core cavity wall of the variable flow cavity valve core, and the outer side surfaces of the five diversion supporting plates are fixedly connected with the excircle inner side wall of the variable flow cavity valve core; the deformed flow channel gradually changes into the valve core circular hole in the upper spherical surface of the valve core from the valve core annular hole in the lower spherical surface of the valve core so as to ensure that the variable flow cavity valve core moves up and down relative to the cylindrical pipe and can do unidirectional circulation at the same time.
