- closed force polygon 合力多边形
- Based on limited balance theory, the formula of force polygon method used to calculate the soil pressure of gravity retainwall for cohesionless soil under water is provided in . 以衡重式挡墙为例,从极限平衡理论出发,推导了无粘性填土在浸水条件下用力多边形法计算土压力公式;结合具体工程实例,对延长墙背法和力多边形法进行了比较。
- Therefore, when a pressurized diaphragm valve is closed to the recommended 10 ft-lbs. and the valve outlet is depressurized, the closing force on the seat is only 4 ft-lbs. 因此，当使用推荐的10ft-lbs力来关闭受压隔膜阀且阀门排气口压力下降时，在阀座上的关闭力量只有4ft-lbs。
- The taper stem head then transfers a vertical closing force to a lateral force which positively seats the knife against the seat face. 然后锥形阀杆头将垂直关闭力转换成侧向力，将闸刀放置到阀座表面上。
- Impactor handwheel gives 3-10 times more closing force than a standard handwheel. All this resulting in smooth, easy operation and tight shutoff under extreme pressures. 冲击式手轮的关闭力比普通手轮大3到10倍。这样就能够在极端压力下顺利、轻松的操作，紧密关闭阀门。
- When closing the valve against cylinder pressure, about 60%of the closing force goes toward pushing the diaphragms down, while only 40% of the force is transmitted to the seat. 当在钢瓶压力下关闭阀门时，关闭力量的大约60%25向下克服气体压力，而只有40%25的力传递到阀座。
