Description

Technical Field

[0001] This utility model relates to the field of wind pressure gauge technology, and in particular to a wind pressure gauge with an anti-blocking sampling structure. Background Technology

[0002] A pressure gauge with an anti-clogging sampling structure is a device used to measure air pressure. It is mainly used to prevent or reduce blockage in soot blowing system pipes. It is usually installed at the inlet of the air pressure measuring tube to measure air pressure, air velocity and pressure drop of the pressure gauge, thereby indirectly obtaining the air pressure value. This device is widely used in soot blowing of pipes in boiler, dust collector and fan systems and in the detection of blockage in dust collector pipes.

[0003] A wind pressure gauge with an anti-clogging sampling structure uses an internal filter plate to block dust particles and protect the normal operation of the measuring equipment. However, the filter holes inside the traditional filter screen are easily clogged by dust particles, resulting in insufficient pressure in the sampling cylinder. In cold weather, when the airflow passes through the filter plate, some water vapor is easily retained on the filter plate, and the water vapor condenses, causing the filter plate to freeze and become clogged.
