Problems solved by technology

However, this kind of mirror body installed on the opening of the pipeline cannot fully observe the situation in the pipeline, especially when the light on site is insufficient, or the color of the fluid in the pipeline is close to that of the inner wall of the pipeline, it is even more difficult to effectively observe the situation in the pipeline
In addition, when the liquid in the pipe contains chemical substances such as hydrogen, fluorine, acid, and strong alkali, ordinary pipe sight glasses cannot be used

Abstract

The invention discloses corrosion-resistant pipe sight glass and belongs to the field of pipe fittings. The corrosion-resistant pipe sight glass comprises a first flange, a second flange, a first pipe, a second pipe, a first end cap, a second end cap, a glass tube, nuts and a screw. One end of the first pipe is connected to the first flange and the other end is connected to the first end cap. One end of the second pipe is connected to the second flange and the other end is connected to the second end cap. The glass tube is arranged between the first end cap and the second end cap. A polytetrafluoroethylene piece is arranged in the glass tube. The screw is arranged between the first end cap and the second end cap. The nuts are arranged at both ends of the screw. The corrosion-resistant pipe sight glass is simple in structure, easy to use, long in service life, wide in application range, high in practicability and capable of being used for effectively observing the situation inside the pipes.

Description

technical field [0001] The invention relates to the field of pipeline fittings, in particular to a corrosion-resistant pipeline sight glass. Background technique [0002] At present, it is widely used that pipelines can meet the distance of liquid flow through flange connection, but in some special industries, the distance of liquid flow is long, and at the same time, it is necessary to understand the working conditions of liquid flow in the pipeline. In the prior art, a pipeline sight glass It is designed to observe the situation in the pipeline. It has a lateral opening on the pipeline, and a flat mirror body is installed on the opening, and the situation in the pipeline can be observed through the flat mirror body. However, this kind of mirror body installed on the opening of the pipeline cannot completely observe the situation in the pipeline, especially when the light on site is insufficient, or the color of the fluid in the pipeline is close to that of the inner wall o...
