CN202791050U 一种防回流高压旋转接头 失效 - 放弃

一种防回流高压旋转接头
摘要：
本实用新型公开了一种防回流高压旋转接头，接头包括接头壳体(2)，接头壳体(2)的一端能转动地设置在接头芯轴(9)上，接头壳体(2)的另一端设置有进油口(21)，接头壳体(2)的另一端固定连接有能封闭进油口(21)的逆止阀。该接头能够在液压系统停止向高压油腔中供油后使高压油腔内缓慢泄压，延长了轧辊芯轴和轧辊辊套的使用寿命。
摘要（英）：

The utility model discloses an anti-backflow high pressure rotating connector which comprises a connector casing (2), one end of the connector casing (2) is arranged on a connector mandrel (9) in rotating mode, an oil feeding port (21) is arranged at the other end of the connector casing (2), and a check valve capable of closing the oil feeding port (21) is fixedly connected with the other end of the connector casing (2). The connector enables a high pressure oil cavity to release pressure slowly after a hydraulic system stops supplying oil to the high pressure oil cavity and prolongs service life of a roller mandrel and a roller sleeve.
