Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see figure 1 , a gas flow sensor calibration device, comprising a calibration table, the calibration table is provided with an air inlet at the front end, and an air outlet at the rear end. The calibration table is divided by three gas rectifiers to form three chambers from front to back. The three chambers are chamber 1 on the side of the air inlet, chamber 2 in the middle, and chamber 3 on the side of the air outlet. The gas rectifiers are respective...

The invention relates to the technical field of air valve calibration, and particularly relates to an air flow sensor calibration device which comprises a calibration table. An air inlet is formed in the front end of the calibration table, an air outlet is formed in the rear end of the calibration table, and the calibration table is divided into three cavities from front to back through three air rectifiers; and two cavities on one side of the air inlet are movable and variable cavities, the cavity on one side of the air outlet is a fixed cavity, the middle cavity is provided with an air valve support used for placing an object to be calibrated, the air outlet of the calibration table is connected with an air outlet pipeline, and the air outlet pipeline is connected with a standard air flow meter used for calibration. The device is suitable for calibration of air flow sensors and all or most specifications of air valves at the same time, and is good in universality, simple, convenient and accurate.
Description
technical field [0001] The invention relates to the technical field of damper calibration, in particular to a gas flow sensor calibration device. Background technique [0002] Dampers with measuring functions are calibrated before leaving the factory. Existing solutions generally use a set of calibration equipment of the same caliber (specification) for dampers of one caliber (specification), so it is necessary to match calibration equipment of different specifications for dampers of different lengths and shapes, resulting in a certain degree of waste of resources. Existing calibration equipment is also relatively complex. It is of great significance for the calibration of air valves to develop a calibration device with high adaptability and easy operation. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a gas flow sensor calibration device, which is suitable for calib...
