This utility model discloses an inflatable sealing device for an environmental chamber, including an air pump. One end of the air pump is an air inlet, and a particulate filter is installed at the air inlet. The other end of the air pump is connected to an air storage tank. The air outlet of the air storage tank is connected to an inflatable sealing strip via a pressure regulating valve and a three-way reversing valve. The inflatable sealing strip has an annular air chamber with an air inlet, which is connected to the inflation port of the inflatable sealing device. This utility model uses an inflatable sealing strip to seal the environmental chamber, ensuring that its leakage rate meets standards. This utility model also provides an inflatable sealing device for the inflatable sealing strip.
Description
Technical Field
The utility model relates to an environment cabin field, specifically speaking, in particular to environment cabin is with aerifing sealing device.
Background
The environmental chamber is a test device for reasonably simulating indoor environmental conditions, and under the operating conditions of the chamber, whether the formaldehyde emission of the artificial board meets the national standard or not is detected. The environmental chamber generally has larger chamber capacity, the chamber door is also larger, the requirement on the isolation effect with the environment is high, and the sealing requirement is high. The environmental chamber for releasing formaldehyde and VOC generally requires that the leakage rate is not more than 1% (flow comparison method). Most of the existing cabin door sealing structures of the environmental cabins adopt sealing strips, and the sealing performance of the sealing strips has an improved space.
