Description

Unidirectional ball valve structure of concentrated dialysis liquid supply system

Technical Field

The utility model relates to the field of medical appliances, in particular to a one-way ball valve structure of a concentrated dialysis liquid supply system.

Background

The common liquid supply ball valve cuts off or opens medium circulation, the opening and closing part (ball) of the ball valve is driven by the valve rod and rotates around the axis of the ball valve, the valve can also be used for adjusting and controlling fluid, and liquid in the valve can flow bidirectionally and is direct without direction. The dialysis machine needs to be disinfected every day, and when the dialysis machine is disinfected, the liquid supply ball valve needs to be closed, so that disinfectant is prevented from entering a pipeline for centralized liquid supply. The one-way liquid supply ball valve can be opened and closed in one way, so that the risk that the disinfectant enters the liquid supply pipeline is reduced. However, the unidirectional ball valve has the problem of poor sealing performance. In order to solve the problem of poor sealing performance of unidirectional flow of the one-way valve, the one-way valve with better sealing performance is provided, such as [ CN 212928845U ], [ CN 216279503U ], and the like. The sealing performance of the check valve is changed by arranging a complex pressure spring structure.
