Assemble the disc screw through the disc washer and disc rubber , and screw it into the disc holder 穿过阀瓣垫圈和阀瓣橡胶组装阀瓣螺丝，并将其旋进阀瓣固定器内。
Threaded - in bonnet is common in lighter - duty services and smaller sizes of bronze multi - turn valves 螺纹旋进式阀盖：通常用于轻型管道系统和小尺寸青铜多回转阀门中。
Valves with threaded - in strength welded seats offer an additional level of safety against fugitive emissions 带有螺纹旋进强度的焊接阀座能够为短时排放提供更高水平的安全性能。
There are two kinds of vortex type oscillatory flowmeter : vortex flowmeter and vortex precession flowmeter 基于旋涡流体振荡原理的流量计主要有两种：涡街流量计和旋进旋涡流量计。
The assembly shall consist of two threaded - in check modules with captured springs and silicone seat discs 这种总成应该由两个螺纹旋进、配置复位弹簧和硅酮阀座阀瓣的止回阀模块构成。
Check modules shall be threaded into the valve adapters and check retainers / spacers shall not be utilized to retainer the check 止回阀模块应该是螺纹旋进到阀体适配器内，不应该采用止回阀固定器/垫片来固定止回阀。
The check assemblies are threaded into the body . to remove the first check assembly , rotate the check module by hand counterclockwise 这种止回阀总成是通过螺纹旋进阀体的。为了拆卸第一止回阀总成，要用手逆时针方向旋转止回阀模块。
Sound in a river entering a narrow canyon or water swirling down the drain becomes distorted and follows a bent path , like light around a star 在流入峡谷的河流中，或是在旋进排水孔的涡流中，声波会变形扭曲，并且沿著弯曲的路径行进，就像是星体附近的光一样。
In this paper , recent advances in the research and development of quantum magnetometers have been described together with some suggestions on further research work 摘要介绍了核子旋进磁力仪、欧弗豪泽磁力仪、光泵磁力仪、超导磁力仪和原子磁力仪研究和开发近况，提出了开展研究工作的建议。
The 775qt series features a modular design which facilitates maintenance and assembly by retaining the spring load . check modules are threaded into the valve adapter for leak proof operation 775qt系列特点是模块化结构，通过保留弹簧负载简化维护和组装。止回阀模块通过螺纹旋进阀门适配器内，提供无泄漏运行。
