valve clack

基本解释

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。
Equalizing feature for rearrangement of counter-balance moment is available in the valve, resulting in less flow resistance loss after opcnning the valve clack.
该阀还安装了调节平衡力矩范围的平衡机构，可以降低阀瓣开启后的流阻损失。
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。
