valve clack

基本解釋

The different flow characteristics could be derived from the different molded lines of the valve clack.
調(diào)節(jié)閥中不同閥芯型線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.
該閥還安裝了調(diào)節(jié)平衡力矩範(fàn)圍的平衡機(jī)搆，可以降低閥瓣開啓後的流阻損失。
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.
採(cǎi)用上述密封結(jié)搆的止廻閥有良好的密封傚果，能有傚地防止閥躰和閥瓣之間的泄漏。
