您要查找的是不是：
- The disc and moving parts may constantly move if the velocity pressure is not sufficient to hold the valve in a wide open and stable position. 如果流速压力不足于将阀门支撑在敞开的、稳定的位置，则阀瓣和其它活动部件将会持续振动。
- They are opened and sustained in the open position by the force of velocity pressure, and closed by the force of gravity. 他是利用流体速度压力来开启和保持在开启的位置，并利用重力的作用来关闭。
- The disc and associated moving parts may be in a constant state of movement if the velocity pressure is not sufficient to hold the valve in a wide open and stable position. 如果流体流速压力无法将阀门支撑在一个较大的开启度并保持在稳定的开启位置，则阀瓣和相关的运动部件可能会处于一种持续振动的状态。
