Embodiment 1

[0024] Such as figure 1 figure 2 image 3 The air volume display tuyere shown includes a tuyere frame 1, a measuring piece 2, a fixing frame 3, a trachea connector 4 and an air volume display 5, and the measuring piece 2 is horizontally arranged in the tuyere frame 1, and one end of it is fixed by The frame 3 is fixed on the inner wall of one side of the tuyere frame 1, and the other end is fixed on the inner wall of the other side of the tuyere frame 1 through the trachea connector 4; the measuring piece 2 is provided with a total pressure average tube hole 201 parallel to the length direction and the static pressure average tube hole 202, the fixed frame 3 seals the total pressure average tube orifice and the static pressure average tube orifice of the measuring sheet end on its side; the trachea connector 4 is provided with two outlet pipe joints, The side of the two outlet pipe joints facing the test piece is respectively in sealing communication with the orifice of the...

Embodiment 2

[0030] Such as figure 1 Figure 4 The air volume display tuyere shown includes a tuyere frame 1, a measuring piece 2, a fixing frame 3, a trachea connector 4 and an air volume display 5, and the measuring piece 2 is horizontally arranged in the tuyere frame 1, and one end of it is fixed by The frame 3 is fixed on the inner wall of one side of the tuyere frame 1, and the other end is fixed on the inner wall of the other side of the tuyere frame 1 through the trachea connector 4; the measuring piece 2 is provided with a total pressure average tube hole 201 parallel to the length direction and the static pressure average tube hole 202, the fixed frame 3 seals the total pressure average tube orifice and the static pressure average tube orifice of the measuring sheet end on its side; the trachea connector 4 is provided with two outlet pipe joints, The side of the two outlet pipe joints facing the test piece is respectively in sealing communication with the orifice of the total pre...

Embodiment 3

[0034] A method for air volume detection, comprising the steps of:

[0035] 1) Install the air volume display air outlet shown in Embodiment 1 or 2 on the air outlet of the air supply duct; make the windward side of the test piece face the air flow direction of the air supply duct;

[0036] 2) Measure the total pressure in the air supply duct through the total pressure average tube hole;

[0037] 3) Measure the static pressure in the air supply duct through the static pressure average tube hole;

[0038] 4) The air volume is obtained from the following formula (1), formula (2) and formula (3);

[0039] Total pressure - static pressure = dynamic pressure (1)

[0040] Dynamic pressure=0.5×air density (kg / m3)×wind speed (m / s) squared (2)

[0041] Wind speed × air volume shows the effective cross-sectional area of ​​the air outlet = air volume (3).

[0042] In practical applications, the air volume detection method can be integrated into the air volume display and the final re...

Abstract

The invention relates to the technical field of tuyere frame air volume measurement, and discloses an air volume display tuyere and an air volume test method. The air volume display tuyere comprises atuyere frame, a test piece, a fixing frame, an air pipe connecting piece and an air volume display, wherein the test piece is arranged in the tuyere frame, and two sides of the test piece are respectively fixed through the fixing frame and the air pipe connecting piece; the fixing frame blocks a total pressure average pipe orifice and a static pressure average pipe orifice on the side where the fixing frame is located; the air pipe connecting piece is provided with two air outlet pipe connectors, the sides, which face the test piece, of the two air outlet pipe connectors are communicated withthe total pressure average pipe orifice or the static pressure average pipe orifice in a sealed mode, and the other sides of the two air outlet pipe connectors are communicated with the air volume display through air pipes. The air volume display tuyere has the beneficial effects that on the one hand, the air volume in the pipeline can be measured and displayed, on the other hand, an air outlet frame of an existing pipeline type air supply device can be replaced, and the effects of low cost and small occupied space are achieved.

Description

technical field [0001] The invention relates to the technical field of air volume measurement of a tuyere frame, in particular to an air volume detection method for an air volume display tuyere. Background technique [0002] In ducted air supply devices such as central air conditioners and fresh air systems, it is usually necessary to measure the air volume of the air outlet in order to control it; The inner cavity and the low-pressure average inner cavity get an average value and then connect it to the external micro-pressure differential sensor transmitter through the channel tube to calculate the average value of wind speed and air volume. On the one hand, the air volume measuring device with this structure has high cost, and on the other hand, it is bulky, and the installation and use are relatively cumbersome. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an air volume display tuyere. [0004] In order to o...
