Abstract

The invention discloses a dredging device and method for a parallel multi-path small-caliber pressure measuring guide pressure hose. The pressure guide hose comprises a first pressure guide hose and asecond pressure guide hose, one end of the first pressure guide hose is provided with a pressure sensing hole, the other end of the first pressure guide hose is connected with the second pressure guide hose, the other end of the second pressure guide hose is connected with a collector, the dredging device comprises a three-way valve, the first pressure guide hose and the second pressure guide hose are connected through the three-way valve, a third connector of the three-way valve is connected with a dredging pipeline, the other end of the dredging pipeline is connected with a micro-positive pressure generating device, a one-way valve is further arranged on the dredging pipeline, and a valve is arranged on the first pressure guide hose. The dredging device is simple in structure, and can effectively dredge the second pressure guide hose when blockage occurs in the second pressure guide hose.

Description

technical field [0001] The invention relates to the technical field of rail transit wind speed detection equipment, in particular to a dredging device and method for parallel multi-channel small-caliber pressure measurement pressure guiding hoses. Background technique [0002] Parallel multi-channel small-diameter pressure guiding hoses are widely used in the field of detection equipment and sensors, such as wind speed detection of rail transit vehicles. When it is applied in a harsh environment, such as an environment with tiny particles such as sand, dust or smog, the pressure guiding hose is easily blocked, resulting in inaccurate measurement results, affecting the normal operation of the equipment, and even causing safety problems. [0003] Therefore, the dredging method of parallel small-diameter pressure guiding hoses is very important for the normal operation of equipment and facilities. However, it is difficult to dredge the small-caliber pressure-guiding hose by me...
