Problems solved by technology
[0003] When two sections of pipelines are connected by flanges, the sealing rings are usually clamped in the two butt flanges, so that the chemical liquid pipelines at both ends are sealed and connected, and the sealing effect is poor, which is prone to leakage; When installing, it is necessary to install a lot of bolts to ensure that the two flanges remain connected. The operation process of connecting and disassembling is very complicated, which makes it very inconvenient to connect and disassemble two sections of pipelines through flanges.

The invention relates to the field of flanges, in particular to a chemical liquid pipeline flange. The flange comprises a first flange and a second flange, wherein the first flange is located on one side of the second flange, the first flange is away from one side of the second flange, a rotating ring is arranged on the side, away from the second flange, of the first flange, and three rotating structures are fixedly connected to the side, close to the first flange, of the rotating ring. According to the flange, by arranging the rotating structures and a negative pressure structure, a drawing plug can slide in a clamping groove, air in the clamping groove can be drawn, a negative pressure environment is formed in the clamping groove, the first flange and the second flange are connected in asealed mode, operation is easy, the sealing effect is good, and liquid leakage is avoided, so that a spring can push a sliding cylinder to slide into a clamping hole, chemical liquid pipelines connected through the first flange and the second flange can be kept in a sealed connection state, the mounting operation process is simple, and the first flange and the second flange are very convenient toconnect and disconnect.
Description
technical field [0001] The invention relates to the field of flanges, in particular to a chemical liquid pipeline flange. Background technique [0002] In modern Chinese, chemical industry, chemical engineering and chemical technology are all referred to as chemical industry, which is of great significance in national economy and engineering technology. Chemical industry permeates people's modern life. Chemical liquid refers to chemical raw materials or chemical products in liquid form. , in the chemical industry, chemical liquids are transported through special chemical liquid pipelines. When two sections of pipelines are connected, they are usually connected through flanges to make the two sections of pipelines sealed, so that the chemical liquids will not leak when they are transmitted in the pipelines. . [0003] When two sections of pipelines are connected by flanges, the sealing rings are usually clamped in the two butt flanges, so that the chemical liquid pipelines a...
