阀门工作状态 Working status of pinch valve
全开：管夹阀的全通径弹性阀套无任何缝隙和死角。

Fully-open: the full-bore elastic valve sleeve of pinch valve without any gaps & dead spots.

关闭中：中线关闭，这一特征避免了套管内的紊流和磨损，阀套成为一个平滑的 封闭的文氏管，每次操作都能自清洗。

Center closed: closed on the center line of the valve body, which avoids turbulence and abrasion, as a result, the valve sleeve becomes a smooth and enclosed venturi with self-cleaning during every operation.

关闭：管夹阀在全关时确保双向零泄漏关闭，采用无密封件需要维护的内在安全

设计。

Fully-closed: it ensures the pinch valve is with no leakage of two ways when shut off, and the safe design of inner valve sleeve requires no maintenance of sealing elements.
