Abstract

The invention relates to a wind volume and wind pressure sensing and pressure receiving device. The wind volume and wind pressure sensing and pressure receiving device is characterized by comprising more than one wind volume and wind pressure sensing rod installed at a wind duct; the sections of the wind volume and wind pressure sensing rods are in the shape of a wing; the top surfaces of the wind volume and wind pressure sensing rods serve as windward surfaces which are in an arch shape; the left sides and the right sides of the middle-lower portions of the wind volume and wind pressure sensing rods are inwards inclined in an arc shape to form wind guide surfaces; windward sensing flow channels and wind guide sensing flow channels are formed in the wind volume and wind pressure sensing rods; first windward openings, second windward openings, third windward openings and fourth windward openings are sequentially formed in the portions, located at the middle lines of the windward surfaces, of the wind volume and wind pressure sensing rods and communicated with the windward sensing flow channels; the portions, on the left side and the right side of each wind guide sensing flow channel, of the corresponding wind volume and wind pressure sensing rod are symmetrically provided with two first wind guide openings, two second wind guide openings, two third wind guide openings and two fourth wind guide openings respectively, and the first wind guide openings, the second wind guide openings, the third wind guide openings and the fourth wind guide openings are all communicated with the wind guide sensing flow channels and located on the middle lines of the wind guide sensing flow channels. The wind volume and wind pressure sensing and pressure receiving device has the advantages of being small in wind resistance and high in wind volume and wind pressure measurement precision.

Description

technical field [0001] The invention relates to an air volume wind pressure sensor and a pressure receiver. Background technique [0002] At present, air volume and air pressure sensors and pressure receivers are drilled through aluminum pipes. When in use, the air volume and air pressure sensor and pressure receiver are installed in a circular pipe; due to the limitation of the shape of the aluminum pipe itself, the hole diameter and hole spacing are not uniform, which affects the airflow reading accuracy and cannot accurately measure the airflow guide. The reading accuracy of the air volume and air pressure on the flow surface is not high, and the indoor temperature cannot be accurately controlled, which fails to achieve the purpose of energy saving and precise control. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide an air volume and air pressure sensor and pressure receiver with small ...
