PRESSURE DETECTING DEVICE

Japanese Patent JP2016114401

A

PROBLEM TO BE SOLVED: To be utilized easily and widely in a general air-conditioning equipment as a configuration capable of suppressing an increase of the total cost in a pressure detecting device used for the detection or the like of a wind volume of the damper of the ventilator.SOLUTION: A pressure receiving bag body 3 formed from a flexible film material which becomes a prescribed three-dimensional shape in a pressed state is installed and fixed so as to block a circulation opening 2 provided on a separation wall body 1 which divides the boundary of a pressure difference. A pressure detecting device is configured to sandwich and hold the pressure receiving bag body 3 in a pressed state pressed by pressure means 5 by a displacement conversion body 4 rotatably fixing one axis to the separation wall body 1 serving as a base. Thus, the displacement volume based on the rotation of the displacement conversion body 4 due to expansion of an internal pressure state of the pressure receiving bag body 3 can be controlled only by a compressive force to be regulated by the pressure means 5 and appropriately enlarged, and can be detected by converting the object pressure into regulation information without complicating the conversion means 6, thereby making it possible to suppress an increase of the total cost of the device and to obtain a pressure detection device easily utilized by the general air-conditioning equipment.SELECTED DRAWING: Figure 1
