An air-conditioning pipeline velocity monitor

Abstract

The invention relates to an air conditioner pipeline flow velocity monitor. The monitor comprises a beam pipe installed on an inner wall of an air conditioner air duct. Several windward plates are arranged in the beam pipe in an array mode. One axial end of each windward plate is rotatably connected to an inner wall of the beam pipe. A free rotation end portion of each windward plate is provided with one fixing plane. Several resistance strain gauges are arranged between the fixing plane and the inner wall of the beam pipe in a linear array mode. Surfaces of the resistance strain gauges are parallel to an axis of the beam pipe. One windward sheet is fixed to the free rotation end of each windward plate. The surface of the windward sheet is inclined relative to the axis of the beam pipe. When the windward sheet bears wind pressure, the resistance strain gauges are tensioned by the windward plates, the windward plates and the windward sheet are coplanar, and the surface of the windward sheet is inclined relative to the axis of the beam pipe.

Description

technical field [0001] The invention relates to a flow rate monitor of an air-conditioning pipeline, which belongs to the field of fluid monitoring equipment. Background technique [0002] In the use of large-scale air temperature control and circulation equipment, it is included in the central duct air conditioner, and more air ducts are often used for air guidance. At the same time, in order to achieve air filtration and heat exchange, the air duct In order to monitor the normal operation of various equipment and components, various types of flow rate monitors will be installed in the pipeline. While monitoring the flow rate of the pipeline, it can realize Automatic control of drainage fans, heat exchangers and other equipment in the pipeline; [0003] The traditional gas flow meter is generally an anemometer. Its basic principle is to place a thin metal wire in the fluid, and heat the wire through an electric current to make its temperature higher than the temperature of...
