Claims (1)

Шаровой кран, имеющий корпус с патрубками, обеспечивающими проход потока, с размещенной в нем шаровой пробкой, поворачиваемой через включающий вал, расположенными концентрично к оси патрубка съемными кольцами, обеспечивающими плавающую опору шаровой пробки, прижимаемыми к шаровой пробке для компенсации осевых допусков при наличии возможности перемещения относительно корпуса, причем по меньшей мере одно из съемных колец имеет уплотнительные поверхности к шару и корпусу с вторичными уплотнениями в виде устройств с возможностью дополнительной смазки и/или мягких уплотнений и концентричную к оси патрубка кольцевую канавку в зоне уплотнительной поверхности съемного кольца к шару, причем в кольцевую канавку уплотнительной поверхности к шару входит контрольная линия продувочного отвода, проходящая через стенку корпуса и съемное кольцо, а также через разделительную полость между ними.A ball valve with a housing with nozzles providing a flow passage, with a ball plug placed in it, rotated through an actuating shaft, detachable rings concentric to the nozzle axis, providing a floating ball plug support, pressed against the ball plug to compensate for axial tolerances when movement is possible relative to the body, and at least one of the removable rings has sealing surfaces to the ball and the body with secondary seals in the form of devices with the possibility of additional body lubricant and / or soft seals and annular groove concentric to the nozzle axis in the area of the sealing surface of the removable ring to the ball, and the control line of the purge tap entering the wall of the housing and the removable ring and also through the separating cavity enters the annular groove of the sealing surface to the ball between them.
