Flange for leakage-proof chemical pipeline

Abstract

The invention relates to the technical field of chemical pipelines, and discloses a flange for a leakage-proof chemical pipeline. The flange comprises a first flange plate and a second flange plate, wherein a first sliding groove is formed in the inner wall of the first flange plate, a sliding block is connected to the inner wall of the first sliding groove in a sliding mode, a sliding rod is fixedly connected to the front surface of the sliding block, a magnetic block is fixedly connected to the inner wall of the sliding rod, a spring is fixedly connected to the top of the sliding rod, an electromagnet is fixedly connected to the top of the spring, a clamping plate is fixedly connected to the bottom of the first flange plate, and a dielectric plate is fixedly connected to the inner wall of the clamping plate. According to the flange for the leakage-proof chemical pipeline, the voltage in a circuit is changed through the dielectric plate, a positive plate and a negative plate, so that the working state of a piezoresistor is changed; and the sliding rod is pushed to move through repulsive force formed between the electromagnet and the magnetic block, and the sliding rod is embedded with a first clamping groove, so that the effect of preventing leakage caused by looseness of the flange plates is achieved.

Description

technical field [0001] The invention relates to the technical field of chemical pipelines, in particular to a leak-proof flange for chemical pipelines. Background technique [0002] Flange, also called flange flange, is a part that is connected to each other between the shaft and the shaft. It is used for the connection between the pipe ends. The flange connection refers to the connection of flanges, gaskets and bolts as a set The detachable connection of the combined sealing structure, some flanges currently on the market are not very leak-proof, and there will be no alarm or reminder when leakage occurs at the connection. [0003] Since the flange and the flange are directly connected by bolts, under long-term use, they may be affected by factors such as vibration or scouring, and the bolts will loosen. Once the bolts loosen, the connection will not be tight. And there is no reminder function and anti-leakage function at this time. Once a leak occurs, it will cause a wast...
