止水装置是闸门活动部份与埋设部份之间的密封装置,用以阻止水流从缝隙渗漏和喷射。因此,止水装置是闸门的重要组成部份。止水装置的好坏,直接关系着闸门运行的可靠程度。如果止水不严密,轻者会带来渗漏损失,使闸门后的检修区排水困难。重者将使闸门产生振动,或因漏水引起冻结(在高寒地区)造成操作事故。特别是深孔闸门。由于水头 Sealing device is the seal between the active part of the gate and the buried part to prevent the leakage of water from the gap and the injection. Therefore, water stop device is an important part of the gate. Water stop device is good or bad, directly related to the reliability of gate operation. If the water is not tight, light will bring leakage loss, so that after the floodgate drainage area difficult. In severe cases, the gate will vibrate or cause freezing due to water leakage (in the alpine region) causing operational accidents. In particular, deep-hole gate. Because of the water head
