　　进口观视镜止回阀 窥视镜逆止阀用途慨述 Overview of use

　　观视镜止回阀（窥视镜逆止阀）用于管道中的流量监测，结合了止回阀和观察镜的特性，通过厚壁硼硅酸盐玻璃可清晰地看到流体通过 RETZ The sight glass check valve (sight glass check valve) is usedfor flow monitoring in the pipeline. Combining the characteristics of the checkvalve and the sight glass, the fluid can be clearly seen through the thick wallborosilicate glass

　　结构 structure

　　1.视镜球型止回阀：内衬阀门结合了浮球止回阀和观察镜的特性，通过厚壁硼硅酸盐玻璃可清晰地看到流体通过 Mirror ball check valve: the lined valve combines thecharacteristics of float ball check valve and sight glass, and the fluid can beclearly seen through the thick wall borosilicate glass

　　2.视镜翻板止回阀：通过翻板打开大小可近似地看出流量的大小，用于观察管道中介质流量的情况。（管道上专用配件、循环冷却水、蒸汽系统配件、电厂供用配配件）Mirror flap check valve: the flow can be approximately seen by theopening size of the flap, which is used to observe the medium flow in thepipeline. (Special fittings on pipes, circulating cooling water, steam systemfittings, power plant supply fittings)
