Air speed measurement device of air gap

Abstract

The invention discloses an air speed measurement device of an air gap. The air speed measurement device comprises an air pipe (7) and an air gap connection device, wherein one end of the air gap connection device is connected with one end of the air pipe (7), the other end of the air gap connection device communicates with an air outlet, an air measurement hole (1) is formed in the air pipe (7) and is a conical hole, a large end surface of the conical hole communicates with the air pipe (7), and a small port of the conical hole communicates with the outside. The air pipe (7) employs a Sause air distribution pipe, and the problem of narrowness of a site condition can be effectively solved; an opening of the air measurement hole (1) is the conical hole, the characteristic of an air measurement device telescopic rod can be fit very well, the sealing condition is favorably ensured during the measurement process, the sealing connection device employs the design of a conical pipe (3), the cross section of the conical pipe (3) is in a trapezoid shape, the assistance of airflow tissue can be reduced, and the leakage rate is further reduced; and the air pipes (7) with different lengths areconnected by air sealing zippers (8), and the adjustability of the total length is ensured.

Description

technical field

[0001] The invention relates to a wind speed measuring device, more specifically, the invention mainly relates to a tuyere wind speed measuring device. Background technique

[0002] GB50243 "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" indicates that the selection of air volume measurement method at the tuyere should meet the following requirements:

[0003] 1. The air volume of the air outlet of the diffuser should be measured by the air volume hood method;

[0004] 2. When the tuyere is a grille or mesh tuyere, it is advisable to use the tuyere wind speed method to measure;

[0005] 3. When the tuyere is a slit-shaped tuyere or the air flow of the tuyere is offset, it is advisable to use the auxiliary air duct method for measurement;

[0006] 4. When it is difficult to test the wind speed method at the tuyere, the air duct air volume method can be used;

[0007] However, in the actual acceptance process, th...

[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a tuyere wind speed measuring device includes an air duct 7 and a tuyere connecting device, one end of the tuyere connecting device is installed on the tuyere, and the other end is connected to one end of the air duct 7, the air duct 7 is provided with a side air outlet 1, and The tuyere 1 is a conical opening, the large end surface of the conical opening is installed on the air duct 7, and the small end surface is far away from the air duct 7, and communicates with the outside world; the conical opening is a good fit for the comparison between the telescopic rod of the anemometer and the sensor end. Small, thicker as it gets closer to the hand-held end, it plays a sealing role during the measurement process. At the same time, the opening extends a distance, so that when the telescopic rod moves up and down, a small part of the wind m...
