This greatly reduces the overall consumption of purge media and the subsequent removal from the process stream 这就大大减少了整个清洗流体介质的损耗，以及相伴随的工业生产液流的损耗。
The valve must be installed with the direction arrow on the body coincident with the direction of the flow in the pipeline 这种阀门安装时，阀体上的箭头方向必须与管路流体介质的流向一致。
Some flow media may further restrict the published temperature limits and / or significantly reduce seat life 有些流体介质可能会进一步限制所公布的温度范围，并且/或者明显缩短阀座使用寿命。
Diaphragm isolates the working parts of the valve from process medium for long life and leak - proof performance 隔膜将阀门的工作部件与所处理的流体介质隔离开来，延长了使用寿命，改善了防泄漏性能。
Gasket rings of different materals will be used for different liquid mediums , products can be supplied as per customersi requirements 使用流体介质的不同采用不同材料的橡胶圈，可根据客户需求提供产品。
Another benefit inherent in the wedgeplug design is that the purge media is only consumed when the valve is being opened or closed 楔塞结构的其他内在优点是只有当阀门开启或关闭时才会消耗清洗流体介质。
Thus it has important theoretic value and practicality to research sound - vibration characteristic of the finite cylindrical shell with stiffener 因此，研究流体介质中有限圆柱壳体的声?振耦合特性具有重要的理论价值和实际意义。
While they are more compact than rising stem valves , the stem threads are always exposed to flowing media , allowing for possible erosion / corrosion 这种结构形式比明杆更加紧凑，阀杆螺纹总是暴露在流体介质中，容易受到侵蚀或腐蚀。
In this paper , the effects of the casing and the fluid media on the electromagnetic wave propagation in oil wells are studied and discussed following the field analysis 首先，采用场分析的方法，分析井内套管和流体介质对电磁波传播的影响。
Some flow media may further restrict the published temperature limits and / or significantly reduce seat life . consul factory for additional information 一些流体介质可能会进一步限制所公布的温度范围，并且明显地缩短阀座的使用寿命。咨询工厂了解更多的信息。
