Abstract
The invention relates to the technical field of testing equipment, in particular to a seal structure for an ultralow temperature environment simulation equipment door. An equipment box wall and an equipment large door are included. An external-use type silica gel seal strip, a medium-temperature type silica gel seal strip, a door edge temperature-resistance device and a box wall temperature-resistance device are arranged between the equipment box wall and the equipment large door sequentially from outside to inside. The equipment box wall is provided with a temperature control heating tape arranged between the external-use type silica gel seal strip and the medium-temperature type silica gel seal strip. The equipment large door is provided with a temperature measurement probe in signal connection with a controller. According to the seal structure, a layering thermal insulation mechanism is designed at the seal position of the ultralow temperature simulation environment testing equipment large door, thus cooling capacity is decreased effectively step by step during exchange with the outside, an insulating layer is provided with a temperature probe used for detecting the temperature after insulating, after analysis through the controller, then whether temperature compensation is conducted is controlled, and the service life of equipment is prolonged.
