1·The different flow characteristics could be derived from the different molded lines of the valve clack.

调节阀中不同阀芯型线可得到不同的流量特性。

2·The check valve by adopting the seal structure has great sealing effect, and the leakage between the valve body and the valve clack can be effectively prevented.

采用上述密封结构的止回阀有良好的密封效果，能有效地防止阀体和阀瓣之间的泄漏。

3·Though there is no condensate water that uses ball-type sealed lever to make the valve clack tightly adhesion to the valve seat, it can prevent the fresh vapor from leakage.

由于阀座孔在凝结水水位以下，形成水封，水、汽自然分离，达到无蒸汽泄漏。
