Mirrors installation of small size, and drive torque is small, simple, rapid, and also at the same time has a good flow regulation and closed sealing characteristics, medium and large caliber endoscopy in areas of low pressure in use, it is the dominant view mirror form can be used for high temperature, corrosion resistance, easy to poisoning, more dangerous, easily crystallized chemical tower in order to ensure its safety in production.
Straight view mirror has the following structural features:
⑴ use J44W-220R DN15 high-pressure shut-off valve in the form, cone seals, PTFE packing.
⑵ valve cover and valve body has a bolt connection, easy disassembly.
⑶ valve and valve stem for the overall structure, the body cavity medium flow path unobstructed, prevent false level.
⑷ monolithic body, dual stem structure, reasonable layout appearance.
⑸ insulation steam valve can pass as a medium heat, to prevent liquid crystal.
⑹ body and tower type vessel welding, raise body temperature, secondary prevention of liquid crystals.
Installation when a controllable endoscopic insulation should pay attention to the question:
⑴ improve sight glass gasket material using corrosion-resistant, anti-aging, high temperature PTFE sheet, when installed gasket sealing surface and visual inspection, may not have radial grooves and scratches
And other defects, the gasket should be installed smooth, precise location, without deflection or center offset, and good contact, to achieve the requirements.
⑵ strengthen the management of the production process indicators strict control pre-distillation column outlet temperature of 120 ℃, pressure 1.765MPa, an absorption tower outlet temperature ≤46 ℃, pressure 1.765MPa, to prevent over-temperature overpressure.
