In this way, the formation of a groove it ABCDEA "∞" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

In this way, also the formation of a groove ABCDEA "∞"-shaped seal space (such as single-head screw, the groove will shun Rao axial screw plate to the mouth through the suction row, unable to form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

For valves with service above 550 psi (3795 kPa), an integral bonnet with a rod seal consisting of a pressure energized seal and a heavy duty braided scraper ring is required.

如果阀门应用在压力500 psi (3795 kPa)以上的应用环境中，则需要配置整体阀盖，带由一个压力自紧密封和一个重型编制平板环组成的杆密封。

The outside sealing component -corrugated tube of valve can affect outside sealing properties of valve. Through finite element analyse of stress state of corrugated tube, the stress status which are under stretch, compress and stretch-compress action are obtained. Combined with test, the stability, detonation pressure and rigidity of corrugated tube are analyzed. The result showed that corrugated tube is safety under working pressure and when stretch-compress displacement is less than 60% of maxmium displacement.

作为阀门外密封元件的波纹管是影响阀门外密封性能的关键部件，通过对波纹管进行有限元分析，初步掌握了波纹管在拉伸、压缩以及拉伸压缩共同作用下的应力状况，同时采用有限元计算和试验相结合的方法，分析了波纹管的稳定性、爆破压力、刚度等，结果表明，波纹管在工作压力下，拉伸和压缩量达到许用位移的60%时，波纹管工作仍是安全的，为阀门开启量的确定提供了理论依据。

Our company has developed many patented technologies and equipment used in car plant's such as automatic or semi-automatic waxing application, door panel and roof ditch sealing application by robot, internal and external car body sealing application by robot, noise damping materials coating application by robot, etc.

公司开发出很多项专利技术和设备应用于汽车厂的自动或半自动喷蜡、机器人的门槛和顶棚沟槽密封、机器人的车身内部和外部的密封、机器人的隔音降噪阻尼材料喷涂等

For reducing cost purpose some glass factories employ mineral oil instead of silicone oil , which deteriorates the sealing behavior of insulating glass unit and bring a lot of damage to insulating glass unit .

密封胶中一般使用硅油作为润滑剂和增塑剂，有些厂家为了降低成本，使用矿物油代替硅油，由此，降低了中空玻璃的密封性能，并给中空玻璃带来了诸多危害。

Two sets of back-to-back assembled mechanical seal BIA, and together with a shared spring can form a double mechanical seal.

由二套BIA机械密封背靠背安装，共用一个弹簧可组成一套双端面机械密封型式。

As a basic rule, some of the lighter styles of granite need to be sealed while many of the darker granites do not need to be sealed.

作为一个基本规则，某些花岗岩需要更轻的样式被密封，而许多更加黑暗的花岗岩不需要被密封。
