Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sight glasses, in particular to a corrosion-resistant and strongly sealed pipeline sight glass. Background Art

[0002] Straight-through sight glasses are widely used as important accessories in pipelines and equipment. They can be used in chemical towers with high temperatures, strong corrosiveness, easy poisoning, high danger, and easy crystallization to ensure their safe production. They have small installation dimensions, small driving torque, simple and quick operation, and also have good flow regulation function and closing and sealing characteristics. Sight glasses are the dominant form of sight glasses in the fields of large and medium calibers and medium and low pressures.

[0003] At present, the Chinese patent with the announcement number CN211402874U discloses a corrosion-resistant and strongly sealed straight-through cross-shaped sight glass, including a straight-through pipe and a sight glass pipe, wherein the sight glass pipe is fixedly connected to a bottom plate at one end away from the straight-through pipe, and the end face of the bottom plate is connected to a cover plate by bolts, and the end faces of the bottom plate and the cover plate close to each other are both provided with grooves. In this utility model, a bottom plate is provided on the sight glass pipe, a cover plate is provided on the bottom plate, and grooves are provided on the bottom plate and the cover plate. An airbag is provided inside the groove, an air pipe and a valve core are provided on the airbag, and a gasket and a sight glass body are provided on the inside of the airbag. The advantage of adopting this design is that the mounting assembly of the sight glass is modular, and it is easy to replace when a part is damaged. After the sight glass is installed, the airbag is inflated from the valve core through an air pumping tool, so that the airbag expands and completely fills and blocks the gap between the gasket and the groove, thereby making it difficult for the medium to leak from the gap, thereby enhancing the sealing of the sight glass.

[0004] Pipeline sight glasses are an important part of equipment, but most of the existing pipeline sight glasses are not equipped with corrosion-resistant and strong sealing effects. Due to the special use environment of pipeline sight glasses, when the pipeline sight glasses are not equipped with corrosion-resistant and strong sealing effects during use, it is easy for the surface of the pipeline sight glasses to be corroded, affecting the service life of the pipeline sight glasses. In addition, when the sealing of the pipeline sight glasses is not strong, it is easy for the pipeline sight glasses to leak, which is inconvenient for users to use. Utility Model Content

Then, the gas monitoring component is fixed to the top of the mounting frame, so that the gas monitoring component can monitor whether there is leakage at the connection of the mounting frame. The pipeline sight glass body includes a base layer.
