Perpendicular positioning installation device of pitot sensor

Abstract

The invention discloses a perpendicular positioning installation device of a pitot sensor. The perpendicular positioning installation device comprises two pressing blocks and a height ruler, the front side and the rear side of the upper portion of each pressing block are provided with a front trapezoid groove and a rear trapezoid groove in the length direction, the two pressing blocks are positioned and connected through the trapezoid grooves formed in the upper portions of the pressing blocks via trapezoid pins, the opposite end faces of the two pressing blocks are provided with end face V-shaped grooves from top to bottom in a cut mode, the two end face V-shaped grooves are opposite to form a positioning channel with a rhombic section, the bottom faces of the two pressing blocks are respectively provided with a bottom face V-shaped groove in the length direction in a cut mode, the angles of the two bottom face V-shaped grooves are the same, the positions between the middle lower portions and the bottom faces of the opposite end faces of the two pressing blocks are cut to form inclined faces, the front side face and the rear side face of each pressing block are respectively provided with a jackscrew used for jacking the trapezoid pins and the top face of each pressing block is provided with a horizontal ruler. According to the perpendicular positioning installation device of the pitot sensor, the pitot sensor can be perpendicular to the axis of a pipeline in the vertical direction, and a connection line of a center point of a total pressure hole and a center point of static pressure hole in a pressure taking head of the pitot sensor is on the axis of the pipeline.

Description

technical field [0001] The invention relates to a vertical positioning installation device for installing a Bitoba sensor on a pipeline. Background technique [0002] The Bitobar sensor is a key component for measuring the fluid flow in the pipeline. When in use, insert the Bitoba sensor into the pipeline vertically from the pipeline wall, and connect the center point of the full pressure hole and the static pressure hole on the sensor to the pressure head. on the axis of the pipe. The installation of the Bitoba sensor needs to open a hole in the pipeline first, and then install the cylindrical pipe seat, which needs to be welded vertically on the pipe wall in a vertical manner, and then insert the Bitoba sensor through the cylindrical pipe Into the pipeline, and make the line connecting the center points of the total pressure hole and the static pressure hole on the axis of the pipeline, and finally fix the Bitoba sensor on the pipeline wall through auxiliary parts such as...

AI Technical Summary

Problems solved by technology

The above-mentioned two principles to be followed when installing the Bitobar sensor on the pipeline are to ensure that the Bitobar sensor is perpendicular to the axis of the pipeline in the vertical direction, and the second is to ensure that the full pressure hole and the static The central point of the pressure hole is connected to the axis of the pipeline, so that the accuracy of the data measured by the Bitoba sensor can be effectively guaranteed. The welding installation of the above-mentioned cylindrical pipe seat and the insertion depth of the Bitoba sensor into the pipeline are mainly determined by the operator. If the cylindrical pipe seat cannot be vertically perpendicular to the axis of the pipe, it is impossible to ensure that the Bitoba sensor is perpendicular to the axis of the pipe in the vertical direction, and it is also difficult to ensure that the sensor is taken The line connecting the center points of the full pressure hole and the static pressure hole on the pressure head is on the axis of the pipeline
