Embodiment Construction
[0021] An embodiment of a verification device for an on-site door and window detector Figure 1~7 As shown: it includes a simulation window 2 and a simulation cabin 43 with a simulation pressure chamber. The simulation window 2 is installed on the rear side of the simulation cabin 43, and the front side of the simulation cabin is provided with a front air outlet for connecting the corresponding on-site door and window detector and the simulation pressure chamber. The rear side of the simulation cabin is provided with a rear air outlet for connecting the simulation pressure chamber and the simulation window, and the bottom of the simulation cabin is provided with walking wheels. The rear side of the simulation window 2 is connected with an instrument cabin 12. The simulation window 2 includes a simulation window body whose front side is the windward side for being installed on the corresponding on-site door and window detector. The simulation window body includes a front side pl...

The invention relates to a calibrating device for an on-site door and window detector. The calibrating device comprises a simulation window and a simulation cabin with a simulation pressure chamber. The front side of the simulation cabin has a front air outlet for connecting the corresponding on-site door and window detector and the simulation pressure chamber, and the rear side of the simulationcabin has a rear air outlet for connecting the simulation pressure chamber and the simulation window; the simulation window has a flow value sampling channel and a pressure value sampling channel; thecalibrating device further comprises a pressure sensor calibrating device connected to the pressure value sampling channel and a gas flow meter calibrating device connected to the flow value samplingchannel. The invention solves the problem that when the on-site door and window detector is calibrated in the prior art, the on-site door and window detector does not conform to the actual working condition, and the calibration is inaccurate.
Description
technical field [0001] The invention relates to a verification device for an on-site door and window detector in the field of verification. Background technique [0002] When installing doors and windows on the exterior wall of a building, it is necessary to test the three physical properties of the doors and windows: wind pressure resistance, air permeability, and rainwater leakage. In the prior art, there are two ways to test the physical properties of doors and windows, one of which is to install the doors and windows to be tested on the on-site door and window detector, and use the on-site door and window detector to test the doors and windows. There is a certain difference between the installation on the building wall and the actual installation of doors and windows, so its detection accuracy is limited. Another detection method is to directly detect the doors and windows installed on the building wall through the on-site door and window detector. One detection port, ...
