Abstract: An on-line sealing detecting device, which is set on a butting surface of two parts, and includes: a seal ring installed in the butting surface of two parts, and a circumferential chamber set in this seal ring ; an inlet and outlet unit connected with the inner of the chamber, and one detection unit set on this inlet and outlet unit. This detection unit is connected with a processor through electric connection and is used for detecting the gas pressure value and/or gas concentration value in the inlet and outlet unit, and for sending the gas pressure value and/or gas concentration value to the processor. An on-line sealing detecting method realizing an on-line detection of part sealing, and detecting each operation position of multi-section-type seal chamber processing equipment at the same time effectively improves the sealing detection efficiency of multi-section-type seal chamber processing equipment.

Abstract: This invention discloses a decontaminating column for on-line replacing adsorption material, and it includes: a tank having an inner tank being used for filling the adsorption material, and one end of the tank being set to be opened; at least one discharging part is being attached to the tank, and an open-close unit by which the adsorption material can be discharged and which is installed between the discharging part and the tank. There is a chamber in the discharging part, which is connected to a gas replacement unit. At the same time, this invention also discloses a glove box.
