[0002] Flange sight glasses are mainly used in pharmaceutical, electronic and chemical industries. Flange sight glasses can observe the preparation, reaction and fermentation conditions in the container. They are an important observation window accessory on the head of stainless steel tank (kettle) containers.
[0003] Compared with the existing technology, there are problems: the conventional flange sight glasses on the market currently have cleaning dead corners, which makes it difficult to pass the riboflavin spray cleaning verification in the tank. The secondary production of the container surface that has not been thoroughly cleaned will have a certain impact on the product quality. For high-end clean liquid preparation tanks, reactors (vessels), fermentation tanks, etc., it is necessary to upgrade and optimize the design of ordinary flange sight glasses to meet the needs of clean tanks. For this reason, we proposed an easy-to-clean flange sight glass. After analyzing the structure of the washable flange sight glass, re-optimizing the design, improving, processing and testing, the update and upgrade of the washable flange sight glass was completed, so that it can be used in high-end clean liquid preparation tanks, reactors (vessels), fermentation tanks, etc., and passed the riboflavin spray cleaning verification perfectly.

[0006] As a further solution of the utility model: a plurality of fixing bolts are arranged on the top of the flange sight glass gland, and the fixing bolts are used to compress, fix and seal the flange sight glass gland and the easy-to-clean flange, and the easy-to-clean flange is welded to the upper head of the clean tank.
[0007] As a further solution of the utility model: an upper mirror sealing gasket is arranged on the top of the mirror glass, and a lower mirror sealing gasket is arranged on the bottom of the mirror glass.
[0008] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0009] 1. The flange sight glass gland and the easy-to-clean flange are provided, and the large angle slope and arc angle transition design at the bottom of the easy-to-clean flange are used to avoid cleaning dead corners during cleaning operations, ensuring that the riboflavin spray cleaning verification can be completed in one step. At the same time, the secondary production of the product is prevented from being affected by the container that has not been thoroughly cleaned, thereby improving the processing quality of the product and thus improving the practicality of the flange sight glass;
[0010] 2. The easy-to-clean flange sight glass is processed from a whole piece, without welding process and welding defects, ensuring that the overall material is completely consistent with the parent material. The inlay step of the sight glass is deepened to ensure the stability and sealing of the sight glass after installation;
[0011] 3. The installation of the mirror glass is sealed by arranging an upper mirror sealing gasket and a lower mirror sealing gasket to ensure the sealing of the flange mirror. BRIEF DESCRIPTION OF THE DRAWINGS
