Functions and differences between sight glasses and floor drains
Thread Content
What are the functions and differences between sight glasses and floor drains? Is it used in a closed pipeline or in an open system? Are there any criteria for selection?
Viewing mirror: It is used to observe the flow of the medium inside the pipeline, usually to determine whether the medium is still flowing within it. The specific settings mainly concern the aspects where the demand for circulating water is significant. Such as the compressor cylinder cooling water, or the compressor oil circuit. The sight glass pipeline is generally sealed. Floor drain: Used to collect wastewater or oily waste when it is discharged through pipes; it is similar to a concentric reducer. The floor drain area is open
I completely agree with what was said above. To add more, in the past we could use sight glasses to observe the separation of water and oil layers in the sedimentation tanks, and we could also visually assess the flow rate of the condensate coming from the coolers. Sight glasses provide a very intuitive way to monitor things, which is quite convenient for on-site operations; they are used in many different places.
If the sight glass is used to check the oil-water separation, oil deposits can accumulate over time in front of it, affecting its functionality. There are now models that come with a white board attached at the back to improve visibility; such sight glasses are commonly known as bull’s-eye glasses. More vivid
Under normal circumstances, after the sight glass is installed, it is usually checked during operation; it remains unobstructed in most cases, and if there is an obstruction, it stays inside； The floor drain? I only check it when I notice something leaking out; by then it’s usually blocked or the flow rate is too high ； If factors such as air and humidity have no impact on the material, drain plugs are generally not used on the pipes; custom funnels can be employed when filling the material.
The places I often go to are food processing plants. Now, in order to create dry workshops, customers generally require us to connect all the drainage pipes to floor drains. Every time material is fed for production, it is necessary to use the material to push the water in the pipes into the drain ； Before the end of each production cycle, it is also necessary to use water to push the materials into the storage tank, and then flush the water down the drain. To roughly see the interface between the material and water, we need to install a sight glass at the point where the pipe meets the drain!
For toxic and flammable media, sight glasses are generally chosen
Mirrors can be used to observe the interior, while floor drains are used to collect fluid that leaks out.
It’s hard to understand; there’s no inherent connection between these two things at all, so what’s there to discuss regarding differences?
Agree with the person above – what’s the connection between these two things? ?
