PRODUCT DESCRIPTION 產品概說  

The flap valve shape is round which is usually installed on embankments or the exit of the pipeline end for he pump and water plant draining water. It prevents the damage from river reflux.

舌閥外型以圓型開口為主,常安裝於防洪牆(堤防)或連結管線之水平出口尾端,供抽水機或水廠管線排放水,排放於堤外時使用,防止河水倒灌之危機。

The velocity of flow helps the valve opened. The weight of flap helps the valve closed.

藉由管內水流速度即可順利開啟;關閉時,則藉閥蓋自身之重量達到關閉。

The flap valve has two designs which are single arm type and double arms type, and it also has self-lubricating  bearing. The valve cover is strong which can bear the water hammer when the valve closed.

舌閥設計可為單臂或雙臂式,並採用自潤式軸承,閥蓋設計堅固能承受關閉時所產生的水錘震動。

 

FEATURES 設計特點

When pump stops, the inlet water level is higher than the outlet water level 10cm, which helps flap valve closed exactly.

當抽水機停機時,舌閥外水位高出內水位10公分時,即可自動關閉。 

Hinge pin is dual shear design.

鉸螺栓為雙剪力設計。

Arm controls the flap movement by the adjustable pivot.

擺臂具有可調式支點,可限制閥蓋轉動。

Anti-locking bar ensures the flap valve open/close in normal situation.

防傾桿之設計確保舌閥之正常啟閉。
