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。

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.

对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法，其计算结果表明，双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值，其计算工作量与winkler弹性地基梁法相当，此外，文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正，由于内力计算过程中节点处的面积被重复计算，使得梁底应力偏小，可能导致计算结果的偏于不安全，修正后的应力值更接近于实际情况。
