Description
Technical Field
The utility model relates to an outside sheathed tube pitot tube of taking can make full use of in wind speed, the amount of wind witnessed inspections process of all kinds of systems such as ventilation, air conditioner, discharge fume, belong to experiment test technical field.
Background
The pitot tube is an important instrument for calculating flow rate by measuring the difference between total pressure and static pressure of a fluid. When the pitot tube is used for measuring the fluid pressure in the pipeline, the measuring end of the pitot tube needs to be inserted into the pipeline at different depth positions according to the diameter or the width of the pipeline. At present, the inserting depth of the pitot tube is controlled mainly by measuring staff through a ruler, and the use is inconvenient.
Disclosure of Invention
The to-be-solved technical problem of the utility model is how to more conveniently fix a position pitot tube measuring position.
In order to solve the technical problem, the technical scheme of the utility model is to provide a pitot tube with a sleeve outside, which is characterized in that the pitot tube comprises a sleeve, the sleeve is of a hollow structure, the front part of the sleeve is provided with a pitot tube pressure measuring end sliding port, and the middle part of the sleeve is provided with a pitot tube static pressure connecting tube end sliding port; a pitot tube capable of freely sliding is arranged in the sleeve; the main body of the pitot tube is a straight pitot tube section, the front part of the pitot tube is provided with a pitot tube pressure measuring end, the middle part of the pitot tube is provided with a pitot tube static compression joint pipe end, and the rear part of the pitot tube is provided with a pitot tube full compression joint pipe end; the pressure measuring end of the pitot tube is positioned in the sliding port of the pressure measuring end of the pitot tube, and the pressure measuring end of the pitot tube is arranged outside the sleeve; the end of the pitot tube static compression joint pipe is positioned in the sliding port of the end of the pitot tube static compression joint pipe, and the connecting pipe end of the pitot tube static compression joint pipe is arranged outside the sleeve; the end of the pitot tube full-compression joint pipe is positioned at the rear part of the sleeve, and the connecting pipe end of the pitot tube full-compression joint pipe is arranged outside the sleeve; and a scale is arranged on one side of the sliding port at the end of the pitot tube static pressure connecting tube.
The utility model has the advantages that: compared with the prior art, the utility model provides a technical scheme simple structure, the casing design that provides, the pitot tube depth of insertion is easily confirmed, experiment operating personnel's of being convenient for use.
Drawings
FIG. 1 is a schematic diagram of an external structure of an externally sleeved pitot tube according to the present embodiment;
FIG. 2 is a schematic diagram of an internal structure of an externally sleeved pitot tube according to the present embodiment;
fig. 3 is a schematic structural diagram of a vicinity of a scale of an external sleeved pitot tube provided in this embodiment.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model relates to a pitot tube with a sleeve outside, which comprises a sleeve 1, wherein the inside of the sleeve 1 is a hollow structure, the pitot tube is arranged in the hollow structure of the sleeve 1, the sleeve 1 further comprises a pitot tube pressure measuring end sliding port 5, a pitot tube static pressure connecting tube end sliding port 6 and a scale 7; the pitot tube comprises a pitot tube pressure measuring end 2, a pitot tube static compression joint pipe end 3, a pitot tube full compression joint pipe end 4, a pitot tube pressure measuring end sliding port 5 and a pitot tube straight pipe section 8.
The pitot tube pressure measuring end 2, the pitot tube static compression joint pipe end 3, the pitot tube full compression joint pipe end 4 and the pitot tube straight pipe section 8 are connected to form a pitot tube for measurement.
The sleeve 1 is provided with a pitot tube pressure measuring end sliding port 5 and a pitot tube static pressure connecting tube end sliding port 6, and a scale 7 is arranged below the pitot tube static pressure connecting tube end sliding port 6.
The pitot tube pressure measuring end 2 is positioned in the pitot tube pressure measuring end sliding port 5 and can slide in the pitot tube pressure measuring end sliding port 5, the pitot tube static pressure connecting pipe end 3 is positioned in the pitot tube static pressure connecting pipe end sliding port 6 and can slide in the pitot tube static pressure connecting pipe end sliding port 6, and the sliding distance can be read through the scale 7.
When the pitot tube measures pressure, the equipment is inserted into the pipeline until the sleeve 1 touches the inner wall surface of the pipeline, and the pitot tube static pressure connection pipe end 3 is pushed towards the pipeline direction to the edge of the sliding port 6 of the pitot tube static pressure connection pipe end. At this time, the scale 7 corresponding to the pitot tube static pressure welding pipe end 3 is set to be 0, and the pitot tube pressure measuring end 2 correspondingly slides to the edge of the sliding port 5 of the pitot tube pressure measuring end.
And according to the determined measuring position in the pipeline, keeping the sleeve 1 still, pulling the pitot tube static pressure connection pipe end 3 outwards to a corresponding scale value on the scale 7, and starting to measure the wind pressure in the pipeline. At this time, the moving distance of the pitot tube static pressure welding pipe end 3 is the distance between the pitot tube pressure measuring end 2 and the inner wall surface of the pipeline.
