Stainless Steel Sanitary Four-way Spherical Sight Glass for Pipeline

The working principle of the stainless steel sanitary four-way spherical sight glass is to collect or divert multiple processes or media through a four-way pipeline structure. When the fluid passes through the four-way node, the transparent spherical observation window provides 360° all-round real-time visual monitoring for operators or automatic detection systems. The transparent sphere is usually made of high-strength tempered glass or other pressure-resistant transparent materials, which can withstand a certain pipeline pressure while ensuring that the flow state of media such as liquids, gases or slurries is clearly visible. Through the sight glass, the operator can directly observe the color, transparency, and whether it contains bubbles or impurities.

The options of the stainless steel sanitary four-way spherical sight glass include:

Connection method: quick installation, welding, flange.

Sight glass material: tempered glass, high temperature and high pressure resistant glass.

Surface treatment: mirror polishing, electrolytic polishing.

Built-in lighting: LED light or explosion-proof lamp.

Pressure level: normal pressure type, high pressure type.

Special functions: explosion-proof, anti-fogging, and cleaning nozzles can be added.

• The transition section inside the stainless steel sanitary four-way spherical sight glass adopts an arc-shaped flow-guiding transition to ensure that no obvious dead corners or vortices are formed when the fluid converges or diverges from four directions.
• The stainless steel sanitary four-way spherical sight glass adopts a 360° equidistant fine polishing process inside and outside, and the finish is below Ra0.2μm.
• The stainless steel sanitary four-way spherical sight glass adopts a floating seal design between the sphere and the stainless steel body. When the pipeline expands and contracts or the pressure fluctuates instantly, the sealing ring can deform slightly adaptively.
• The stainless steel sanitary four-way spherical sight glass has multiple micro-temperature sensor installation channels reserved between the cavity of the sight glass sphere and the four-way wall thickness, which can simultaneously monitor the temperature difference of fluids in different flow directions.
• The stainless steel sanitary four-way spherical sight glass is equipped with a micro-sampling or negative pressure sampling port on the top or side wall of the spherical sight glass, and trace liquid samples inside the pipeline can be extracted without disassembly.
• The stainless steel sanitary four-way spherical sight glass is designed with a micro-guide groove at the junction of the sight glass and the body, which automatically collects and discharges the condensate by using the surface tension difference of the condensate.
