斯派莎克双窗观视镜，法兰、螺纹连接，随口径不同提供青铜和黄铜材质的产品
英国斯派莎克双窗观视镜/观视镜止回阀组合
斯派莎克观视镜可提供不同的材质和连接方式，能广泛地应用于蒸汽系统及其它工业液体系统中。将一个斯派莎克观视镜固定地安装在蒸汽疏水阀下游，就可以检测疏水阀是否正常工作。当数个疏水阀集中排放到一个封闭的冷凝水回收系统中时，观视镜可方便的用于检验每个疏水阀的工作情况。
此外，观视镜还可以提供有关蒸汽系统其它方面的情况。例如观视镜玻璃如有同体沉淀物而变得模糊，可判断蒸汽中含有游离的氧和二氧化碳，因而引起凝结水管的腐蚀，也可判断锅炉给水中有机物沉淀。
斯派莎克观视镜有两种类型，即单窗型和双窗型。双窗型为“透视”式，在大口径产品中为标准类型，可以利用背光，便于观察流动状况。
英国斯派莎克双窗观视镜止回阀组合式将观视镜和止回阀组合成一体，如果共疏水阀后面冷凝水有上升，这种装置省去一个止回阀，可简化安装
英国斯派莎克双窗应安装在容易观察的地方。对于用来监测蒸汽疏水阀泄漏的观视镜应安装在疏水阀的下游，对于喷排式排放冷凝水的疏水阀如热动力TD型，应安装在疏水阀后至少1米的距离。
观视镜可通过目测快速检查你的系统。

Sight Glasses / check valve combination Sight Glasses
Spirax Sarco Sight glasses are available in different materials and connections, can be widely used in steam systems and other industrial fluid systems. The concept of an endoscopic Spirax Sarco steam trap fixedly mounted downstream , it can detect the trap is working properly. When the number of traps concentrate discharged into a closed condensate recovery system, sight glass can be easily used to test the operation of each trap .
In addition , the concept of endoscopic steam system can also provide information on other aspects of the case . For example , if the same concept as the body of the crystal precipitate was blurred , can determine the steam containing free oxygen and carbon dioxide , thereby causing condensation pipe corrosion , boiler feed water can determine organic matter precipitate.
Spirax Sarco Sight glasses are of two types , namely single -and dual- window-type windows . Double window type is " perspective " type , in large-caliber products as the standard type , you can use the backlight , easy to observe flow conditions .
Sight glasses of school Sarco the concept of modular check valve and check valve endoscopy combined into one, if the total condensate trap behind the rise , this device eliminates the need for a check valve, simplifies installation
Sight glasses should be installed in easily observable . For leaking steam traps used to monitor the viewing glass should be installed downstream of the trap , the spray Exhaust emission condensate trap as TD -type thermal power , should be installed at a distance of at least 1 meter after the trap.
Sight glasses can quickly check your visual system .
