Description

Technical Field

[0001] The utility model relates to the technical field of air duct wind pressure detection, in particular to an air duct wind pressure detection component. Background Art

[0002] Duct wind pressure detection mainly measures the pressure of the gas in the duct. This process is carried out in the pipe section with relatively stable airflow. The orifice for measuring the total pressure of the gas should face the direction of the airflow in the duct, and the orifice for measuring the static pressure should be perpendicular to the direction of the airflow. The wind pressure detection component is an indispensable part of the wind pressure sensor. The wind pressure sensor is installed on boilers, burners, wall-mounted boilers, and water heaters. The operation of boilers, burners, wall-mounted boilers, and water heaters is automatically controlled through the fluctuation of the wind pressure index. The accuracy of the wind pressure detection component directly affects the operating efficiency of boilers, burners, wall-mounted boilers, and water heaters as well as the emission of pollutants after combustion.

However, the wind pressure detection component needs to be cut and grooved on each pipe during installation, which not only causes damage to the pipe, but also increases the difficulty of installing the wind pressure detection component, which is not conducive to the installation of the wind pressure detection component. In view of the above problems, a wind pressure detection component for a duct is proposed. Utility Model Content

[0033] At the same time, an elastic rubber gasket 218 is added to the outside of the pressure plate 213. The rubber gasket 218 fits against the inner wall of the pipe. The rubber gasket 218 can serve as an intermediate buffer to prevent the pressure plate 213 from contacting the inner wall of the pipe too much and causing damage to the pipe. There is no need to cut or groove the pipe, which is beneficial to the subsequent use of the pipe. The device uses a wind pressure detection connector 13, an aluminum tube 17 and a fan assembly 12 to detect whether the air duct is ventilating normally and whether the equipment is operating normally, which is convenient to use.
