Abstract

The invention relates to a calibrating device for a building exterior door and window testing machine. The calibrating device comprises a simulation window. The simulation window has a pressure sampling channel and a flow rate sampling channel; a gas flowmeter calibrating unit for calibrating a gas flowmeter of the building testing machine and a pressure sensor calibrating unit for calibrating a pressure sensor of the building testing machine are connected to the simulation window; the gas flowmeter calibrating unit includes a flow calibrating gas path connected to the flow rate sampling channel; the flow calibrating gas path is connected to at least two standard flow meters that can work separately; the pressure sensor calibrating unit includes a pressure calibrating gas path connected tothe pressure sampling channel; the pressure calibrating gas path includes at least two standard pressure sensors operating separately and a spiral pipe connected to the upstream of the standard pressure sensors in series. The invention solve the problem that the stand pressure sensors are arranged in a scattered manner in the prior art, which leads to troublesome transportation and a cumbersome calibrating process of the calibrating device.

Description

technical field [0001] The invention relates to a verification device for a building exterior door and window testing machine in the field of verification. Background technique [0002] Doors and windows need to be installed on the exterior wall of the building. For doors and windows, it is necessary to test the three mechanical properties of wind pressure resistance, air permeability, and rainwater permeability. A testing machine capable of testing doors and windows is called a door and window testing machine. Existing door and window testing machines, such as the ZMC series door and window testing machine produced by MIS Industrial Systems (China) Co., Ltd., the door and window testing machine includes a testing machine frame. The real doors and windows are installed on the testing machine frame. The door and window testing machine includes a suction fan and rain equipment installed on the testing machine frame. The suction fan can generate positive and negative pressure o...
