Flange sight glass and wafer sight glass I think that is to say this kind of commodity. The standard name of the Ministry of chemical industry is high-pressure vessel flange sight glass. Due to the structure, that is, a whole piece of laminated glass is sandwiched between the two tablet flanges, which is called tablet flange sight glass by many people; Because the laminated glass is fixed by the two flanges, it is also called the clamp flange sight glass.
1、 Principle of flange sight glass and relevant professional knowledge
The installation specification is small, the driver torque is small, the actual operation is simple and fast, and it also has the characteristics of excellent total flow adjustment and closing sealing. This is the core flange sight glass mode in the application industry of large and medium specifications and low and medium working pressure.
Main application: the flange mirror can be used in the tower of chemical plant with high temperature, strong corrosion, easy poisoning, great risk factors and easy crystal formation, so as to ensure its production a complete. Structure: the flange mirror is mainly composed of flange mirror base plate, flange mirror laminated glass, gate valve components, etc.
2、 Frequently asked questions
(1) change the material of flange gasket.
The PTFE plate with corrosion resistance and heat resistance shall be applied. During installation, the raised surface and sealing gasket shall be solved to carry out appearance inspection, and there shall be no defects such as axial pipe groove and scratch. The rubber sealing gasket shall be installed and leveled, the position shall be accurate, there shall be no inclination or deviation of management center, and the touch shall be excellent, which exceeds the application regulations.
(2) improve the management method of production process index value.
Strictly control the exhaust temperature of the pre distillation tower at 120 ℃, the working pressure of 1.765mpa, the exhaust temperature of the primary absorption tower ≤ 46 ℃, and the working pressure of 1.765mpa to avoid overheating and overpressure.
Sight glass refers to a device used to observe the materials inside containers and equipment. It is a complete accessory and should be inspected regularly. According to the shape, it is divided into circular and rectangular mirrors. According to the purpose, it is divided into peeping and lighting mirrors. According to the structure, it is divided into mirrors with lining and without lining, with neck, with cover, double-layer a full, thermal insulation, with scraper, with flushing device and mirrors suitable for powdery materials.
Sight glass for the petroleum, chemical industry, chemical fiber, medicine, food and other industrial production equipment, to facilitate odservation of any meterial inside the device operating conditions.
316 flange sight glass is our common type sight glass/ flow indicator, double windows can help monitoring clearly.Suitable for a variety of environments, wide range of use.
