Automatic cleaning method and system for gas pressure tapping pipe

Abstract

The invention relates to an automatic cleaning method and system for a gas pressure tapping pipe. The method comprises the following steps: turning on a power supply, and after a first set time, controlling an electromagnetic valve K2 to be closed through a time controller, and then controlling an electromagnetic valve K1 to be opened; inputting a back flushing gas into a metal pipe through a back flushing gas supply device, so as to enable the back flushing gas to enter a pressure tapping pipe; and after a second set time, controlling the electromagnetic valve K1 to be closed through the time controller, and then controlling the electromagnetic valve K2 to be opened. According to the method and system, on-line automatic timing back flushing of the pressure tapping pipe is realized, unobstructed pressure tapping pipe is ensured, and normal operation of a detection system is ensured.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, and more specifically relates to an automatic cleaning method and system for gas pressure-taking pipes. Background technique [0002] The use of pressure (source) tubes is very common in the fields of pressure, flow detection, and gas analysis. To measure the pressure on the pipeline, it is generally necessary to install a special pipeline for measuring pressure on the pipeline, that is, to install the pressure tube. When the pressure tube is in use, the pressure induction tube is often blocked, which affects the detection effect, thereby affecting the production efficiency and production quality, and some toxic and harmful gases will cause harm to personnel during the maintenance process, and at the same time increase the maintenance cost ; After research and testing, it is found that the main cause of pipeline blockage is the dust contained in the measured medium gas. Therefore, it is...
