1·Returning the lever to its normal position releases the tension on the rod permitting the valve to maintain normal system pressure.
将手柄恢复到正常位置，则“压杆”上的压力就得到缓解，使得调节阀能够保持正常的系统压力。
2·The experimental results under idling shows that the elastic prop model tension system is better than lever-weight-tightening the system.
通过在空载条件下的实验结果对比，表明在一定范围内带锯机弹性挺杆式张紧系统优于原杠杆压砣式张紧系统。
3·Highly lever and advanced performance of our products on stabilization and tension strength etc are better than other competitors.
产品的稳定、抗拉强度、收缩性均超同行先进水平。
