Straight endoscopic installation of small size, and the 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.
Mirrors used in petroleum, chemical, steel, pharmaceuticals, thermal power, food, paper and other industrial production plant, ready to observe the reactions flow of liquid, gas, steam and other media, is to protect the safety in production indispensable accessory.
The main technical parameters:
1, housing material: carbon steel, stainless steel, glass and steel.
2, Windows Material: soda lime glass, steel and borosilicate glass, quartz glass, plexiglass.
3, the sealing material: nitrile rubber, PTFE, graphite composite.
4, the working pressure (Mpa): PN0.6 ~ 25, if higher pressures customer requirements, can be customized.
5, the working temperature: -200 ℃ ~ + 280 ℃; -500 ℃ ~ + 1500 ℃.
5, flange standard: GB81-59, other flange standards, please specify the user: If HG, ANSI, ASME, HGJ, DIN, JIS and so on.
1, depending on the mirror installation
Welding flange must be clean and not damaged by the professionals to operate.
2, sight glass lens mounting
Convinced that, as the lens holder smooth, sealed lens and lens holder, as the pad is mounted between the flat gasket no damage and stick grease Before fastening screw is determined as the mirror base and the cover is installed correctly, and then slowly tighten the screws.
3, depending on the mirror must work within the allowable pressure range, otherwise it can not guarantee the safe operating temperature range: soda-lime glass maximum allowable temperature of 150 ℃, dramatic range temperature of 120 ℃ to 20 ℃ tempered borosilicate glass. The maximum allowable temperature of 280 ℃, abrupt changes in temperature range of 230 ℃ to 20 ℃. maximum allowed temperature of the quartz glass is 1500 ℃, abrupt changes in temperature range of 500 ℃ to 20 ℃.
