使关闭

Driven by the valve stem to close one to wind the rotatory central point while rotating,the spheroid to the third a bit more separately, relative valve central point at this moment,from the third orbit a bit one cam form partial another,enter valve flat make valve it keep sealing to shut off down wards .

由阀杆带动关闭件绕旋转中心点转动时，球体由另点移至第三点，此时相对阀门中心点，从另点的第三点轨迹为一凸轮状偏心，向下进入阀座使阀门关闭保持密封。

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。

Its principal is, such product can control some genes, reopen those genes that been closed while you were young, and close genes which leads decrepitude. This is a profound change in human life.

The dish washer includes one washer body with inside washing tank, rotary door in the front of the washer body, and one sealing latch set between the washer body and the door to raise the sealing property of the door. The sealing latch includes one hook unit set inside the hole on the washer body side, one sealing unit exposed outside the washer body and contacting closely to one side of the door in close state, one central slot for telescoping the hook unit, and one expansion joint in the joint part to avoid concentration of stress.

本发明包括洗碗机内部具备了洗涤槽的本体，设置在本体的前面转动的门，设置在本体前面和门之间，当关闭门时提高门和本体前面的封闭性的碰销；其中碰销包括：在本体前面一侧形成的插入孔中设置的挂钩部，露出于本体外部，在门关闭时，紧贴门一侧面的密封部，为了使挂钩在插入孔内直径方向伸缩，而在其中央部位形成的切缝，其特征在于密封部上形成了与切缝相通，防止挂钩伸缩时应力集中到挂钩部和密封部之间结合部位上的伸缩槽。

Are hidden drawer rail damper, so that when the soft closing drawers closed; buffer gate doors are hinged, so that when the soft close doors closed, high-quality metal parts, fully human.

Machine work, dehumidification within the host opened the door, outside the doors closed, private environment-friendly desiccants absorb moisture inside, and then close the inner door, outer door opened, dedicated heater heating the desiccant to evaporate into water vapor outside the box, the above link automatic cycle, and gradually reduce the humidity inside.

机器工作时，除湿主机内门打开，外门关闭，专用环保型干燥剂吸取箱内水汽，之后内门关闭，外门打开，加热器加热专用干燥剂，使水汽蒸发到箱外，以上环节自动控制循环进行，逐步降低箱内湿度。

The tunnel fire happened in the head part of the train is simulated by FLUENT, On different condition, say, all screen doors opened and eight screen doors closed near fire, fire simulation was processed respectively, with the comparison-analyzing afterwards, In the situation of partly-open-screen-doors, smoke was under control more efficiently, with less spread to platforms, which was better for the evacuation.

运用FLUENT软件对列车前部起火的隧道火灾进行了模拟，选择了屏蔽门全部开启和关闭靠近火源一侧的8个屏蔽门两种情况进行了数值模拟，并对模拟结果进行了比较分析。结果关闭靠近火源一侧的部分屏蔽门，可以使烟气得到更好地控制，扩散到站台的烟气量较少，更利于人员的疏散。

To close the headpin, making a loop with round nosed pliers and then twisting the wire around the loop will make a more professional and secure closing than just making a loop.
