Abstract

The invention discloses an anti-blocking device for a high-dust measuring pressure tapping pipeline. The anti-blocking device comprises a timing controller and at least one reverse blowing pipeline. Each reverse blowing pipeline comprises a header air inlet valve connected with an original air supply, an electromagnetic valve connected with a transmitter and a reducing valve connected between the header air inlet valve and the electromagnetic valve. The timing controller is in coupling with the header air inlet valve and the electromagnetic valve for timed control of starting and stopping of the header air inlet valve and the electromagnetic valve. The anti-blocking device can automatically runs, it is ensured that the pressure tapping pipeline is not blocked, and normal operation of a measuring device is not influenced in the blow-sweeping process; and the manual labor intensity is reduced, and safe operation of a system is ensured.

Description

technical field

[0001] The embodiment of the present invention relates to an anti-blocking device for a high-dust measurement and pressure-taking pipeline. Background technique

[0002] In the process of industrial production, there is a lot of dust in some harsh working conditions, and the pipelines of the pressure gauges for measuring and taking pressure will be blocked due to the accumulation of dust, which cannot correctly reflect the actual process conditions. When it is found that the pipeline blockage of the pressure measuring instrument cannot be detected in real time, it is necessary to go to the site to manually purge. In order to prevent pipeline blockage from affecting production, it is necessary to arrange a special person to be responsible for manually purging from time to time, thus wasting a lot of manpower and material resources.

[0003] The existing purge system is manually purged from time to time, requiring special personnel to open the valve of the air...
