Example Embodiment
[0054] Example one
[0055] The present application discloses an ultra-low energy consumption building airtight test method. Refer figure 1 and figure 2 The airtight test method of ultra-low energy consumption buildings includes the following steps.
[0056] S1, measurement basic data: measurement test spatial volume and enclosure structure surface area, measurement test space outdoor wind speed, indoor and outdoor temperature, indoor and outdoor air pressure;
[0057] S2, adjust the opening and closing state of the building component: Test the door and window inside the test space to turn on, turn off the doors and windows of the test space and non-test space, and the test space communicate with the non-test space is closed by the blocking device;
[0058] S3, mounting drum door 1: Install the drum damper 1 test system, and seal on the peripheral side of the blast door 1;
[0059] S4, positive pressure test: Test the static pressure of the test space, after the static pressure te...
Example Embodiment
[0080] Example 2
[0081] Refer Figure 10 The difference between the second embodiment of the present application is that the sealing device further includes a support mechanism 7, and the support mechanism 7 is used to support the extrudation ring 42 in the vertical direction, and the support mechanism 7 includes a pad 71 by a bolt. The electric push rod 72 on the plate 71, the push rod end of the electric push rod 72 abuts against the peripheral wall of the extruded ring 42. The support mechanism 7 can support the extrusion ring 42 in the vertical direction, and avoid the effect of blocking cover 2 and the extrudation ring 42 gravity on the annular suction cup 3, so that the annular suction cup 3 is stably sealed in the vicinity of the hole, which is advantageous Improve detection accuracy.
