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。

Close the valve, the need to open and close with the Coma Berenices two pieces of the sealing surface of the seal formed between certain specific pressure, while also overcoming the stem and the packing between the stem and the nut thread Automatic Control Valves between the stem end bearing at and other friction parts of the friction, and therefore must apply the closing force and closing a certain moment, the valve in the open and close the process, the required hoisting hoisting force and moment of change, and its maximum is close to the final instant or open the initial transient.

关闭阀门时，需要使启闭件与发座两密封面间形成一定的密封比压，同时还要克服阀杆与填料之间、阀杆与螺母的螺纹之间、阀杆端部支承处及其他磨擦部位的摩擦力，因而必须施加一定的关闭力和关闭力矩，阀门在启闭过程中，所需要的启闭力和启闭力矩是变化的，其最大值是在关闭的最终瞬时或开启的最初瞬时。

For example, at 250 ℃ steam valve, the use of asbestos packing and co-lead by alternative Diego, the situation would reduce the steam leakage; some valves, medium constantly changing, such as the asbestos packing and Teflon tape common use, seal it better.

例如，在250℃蒸气阀门中，用石棉盘根和铅圈交替迭合，漏汽情况就会减轻；有的阀门，介质经常变换，如以石棉盘根和聚四氟乙烯生料带共同使用，密封效果便好些。
