Therefore, the torque required to open the gate valve required torque than the closure of large, in addition, for a pair of contact between the sealing surface, the Non Rising Stem Resilient Seated Gate Valves coefficient of static friction between them than the dynamic friction coefficient, to make them from the static state generate the relative movement is required to exert greater force to overcome the static friction; due to temperature changes, so that the sealing surface pressure between the larger, need to overcome the static friction force also will be bigger, so that when you open the valve on the stem nut on the sometimes increase the torque exerted a lot.

所以，开启闸阀所需的力矩比关闭闸阀所需的力矩大，此外，对于一对互相接触的密封面来说，它们之间的静摩擦系数也比动摩擦系数大，要使它们从静止状态产生相对运动，需施加较大的力以克服静摩擦力；由于温度变化，使密封面间的压力变大，需要克服的静摩擦力也随之变大，从而使开启闸阀时，对阀杆螺母上施加的力矩有时会增大很多。" Moment analysis of valve operation "是由中国闸阀网提供的国际阀门新闻，译文仅供参考。另外，中国闸阀网还提供相关产品搜索：闸阀型号、闸阀价格、闸阀技术、闸阀新闻、闸阀生产商等。
