LOCKING ELEMENT OF THE BALL COCK Russian patent published in 2017 - IPC F16K5/06 F16K5/20 

FIELD: machine engineering.

SUBSTANCE: ball cock contains the body of a plug made with a through hole and mounted in its housing with the ability to rotate. Removable main saddles with a sealing surface are installed on the plug in the corresponding grooves and bolted so that the axis of the removable main saddles is perpendicular to the axis of the through hole of the plug. The body of the cork is made in the form of a cube. The plug is additionally fitted with auxiliary removable seats with a sealing surface. The axis of the auxiliary seats is aligned with the axis of the through hole in the plug. The sealing surface of all saddles is made in the form of a sphere of the same diameter. The main and auxiliary seats are interconnected so that their sealing surfaces along the interface line form one continuous surface. Removable main seats are sealed against the plug with rubber rings and are attached to it by clamps made in the form of rings. The clamp is protected in a split ring, inserted into a groove made on the surface of the main seat. The groove is interfaced with the groove on the plug. Auxiliary saddles are installed on the plug in the grooves, made concentrically through the hole in the plug, and fixed with locking screws.

EFFECT: simplifying the design and increasing the maintainability of the ball cock.
