An environmental chamber with pressure balance control

Abstract

The invention relates to the field of design of environmental test chambers, in particular to an environmental chamber with a pressure balance control function.The environmental chamber comprises a regulation window opening, a window body and a counterweight mechanism.The regulation window opening is penetratingly formed in one wall of the environmental chamber; the window body identical to the regulation window opening in shape is in hermetical fit with the regulation window opening, the top of the window body is hinged to the wall, and the window body is capable of rotating around a hinge point with the wall towards a direction away from an inner cavity of the environmental chamber; the counterweight mechanism is detachably arranged on one lateral side, away from the inner cavity of the environmental chamber, of the window body and has a preset weight.The environmental chamber with the pressure balance control function has the advantages that when an acting force of an internal air pressure of the environment chamber on the window body is larger than a pressure force jointly formed by the window body and the counterweight mechanism, the window body can be pushed to rotate around the hinge point with the wall to open automatically, and accordingly air in the environmental chamber can be released for pressure relief; the window body can be hermetically reclosed when pressure balance is reached.

Description

technical field [0001] The invention relates to the field of environmental test chamber design, in particular to an environmental chamber with pressure balance control function. Background technique [0002] For sealed environment rooms, such as clean rooms, freezers, etc., the indoor pressure changes will be caused by changes in airflow organization or air contraction and expansion; if the indoor pressure balance does not meet the requirements, the outdoor air will enter the room, which will affect the indoor environment. Adverse effects on the life of indoor sealing components or equipment products. Especially for some situations where the air intake is large, the indoor pressure may change greatly in a short period of time, causing damage to the indoor structure and seriously threatening the safety of personnel, equipment, and products. Therefore, in the environmental chamber, the pressure balance regulation is a very critical part. Contents of the invention [0003] ...
