Air conditioner duct flow rate controller

Abstract

The invention relates to an air conditioner duct flow rate controller. The controller comprises a beam pipe arranged on the inner wall of an air conditioner duct, wherein the beam pipe is internally provided with an windward plate, a vent hole is formed in the middle of the upwind plate, and a plurality of windward sheets are arrayed and fixedly arranged in the vent hole; one axial end of the windward plate is rotationally connected with the inner wall of the beam pipe, and a resistance strain gauge is arranged between the inner wall of the beam pipe and the rotary connecting end of the windward plate; the other axial end of the windward plate is connected with the inner wall of the beam pipe through an elastic frame comprising a plurality of spring connecting wires among which a venting gap is arranged; and when the spring connecting wires are tensioned, the resistance strain gauge is tensioned by the windward plate, the windward plate and the axis of the beam pipe are arranged obliquely, and the surfaces of the windward sheets are parallel to the axis of the beam pipe.

Description

Technical field [0001] The invention relates to an air-conditioning pipeline flow rate controller, which belongs to the field of fluid monitoring equipment. Background technique [0002] In the use of large-scale air temperature control and circulation equipment, a central air duct type air conditioner is often used to guide air. 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 flow rate monitors will be installed in the pipeline to monitor the flow rate of the pipeline while monitoring the flow rate of the pipeline. Automatic control of draft fans, heat exchangers and other equipment in the pipeline; [0003] The traditional gas flow meter is generally an anemometer. The basic principle is to put a thin metal wire in the fluid, and pass the current to heat the metal wire to make the temperature higher than the temperature of the fluid. Therefore, the wire anem...
