The different flow characteristics could be derived from the different molded lines of the valveclack.
调节阀中不同阀芯型线可得到不同的流量特性。

The check valve by adopting the seal structure has great sealing effect, and the leakage between the valve body and the valveclack 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。

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