Description

TECHNICAL FIELD

[0002] Pipeline sight glass is a key component for observing the flow state of the medium in industrial pipeline systems, widely used in chemical industry, pharmaceutical industry, energy industry, etc. Traditional pipeline sight glass is usually made of transparent glass or polymer material, suitable for visual monitoring of conventional liquids or gases. However, when the medium in the pipeline is transparent gas (such as chlorine, hydrogen sulfide) or low flow rate liquid (such as high viscosity organic solvent), the flow state of the medium is difficult to observe directly through the conventional sight glass.

[0003] In addition, when transporting medium containing crystalline components (such as ammonia, some salt solutions) or strong corrosive medium, the medium is easy to condense, crystallize and firmly adhere to the inside of the sight glass, forming a shielding layer. For example, the reaction of acid gas (such as HCl) with silicate in glass causes the surface of the glass to corrode and become rough; the crystalline liquid (such as sodium sulfate solution) precipitates crystals when the temperature changes, which accumulate on the surface of the sight glass.

[0004] The patent with application number "CN202420517853.1" discloses a pipeline sight glass with an indicating device, which includes a valve body, the valve body includes a medium inlet and a medium outlet, an indicating swing plate is provided between the medium inlet and the medium outlet, the indicating swing plate is rotatably connected with the inner wall of the valve body, the size of the indicating swing plate is larger than that of the medium inlet, sight glass tubes are provided on the upper and lower sides of the indicating swing plate, the sight glass tubes are fixedly connected with the valve body, and a heat preservation device is provided outside the valve body.
