Description
Technical Field
The invention relates to the technical field of sealed operation environments, such as a sealed operation box, a nitrogen and argon protection box, a radioactive operation box, a glove type operation box and the like, and particularly relates to a sealed door assembly and a sealed box.
Background
The sealed box is a box body made of metal, glass or plastic and is applied to the technical fields of sealed operation boxes, nitrogen and argon protection boxes, radioactive operation boxes, glove type operation boxes and the like which need sealed operation environments. These enclosures typically include a door for the enclosure to allow for the replacement of materials, maintenance or assembly of cables or ports, etc. The main housing of a glove box, for example, has a plurality of openings for receiving windows, transition compartments, windows for glove ports, cables, and the like. Operators operate materials and equipment in the box body through the windows or the doors so as to meet the requirements of isolating one or more active components in the air such as oxygen, moisture, carbon dioxide and other sensitive components in the scientific research and production process to realize operation in a closed environment or meet the protection requirements of toxic and radioactive harmful substances.
The sealers have a problem of possible leakage, for example, it is difficult to make the water and oxygen impurities in one sealer less than 1PPM (parts per million) each even if the sealers are filled with high-purity gas. In the normal use process, water and oxygen can also continuously and gradually rise, so that the concentration of the water and the oxygen in the box is far greater than the required concentration. The sealing requirements for toxic or radioactive environments are also very high.
During daily use and maintenance of the seal box, air permeates into the glove box through tiny gaps, the common main box body and the window, and the glove interface fittings or the door assembly are sealed by rubber seal rings, and tiny gaps are inevitably formed around the seal rings; and trace oxygen and moisture can be brought in when materials and equipment are transferred from the outside of the glove box to the inside of the glove box.
For example, the door assembly of the seal box is used as a key assembly for connecting a power supply and other equipment in the seal box, and the penetration piece has good gas sealing performance, so that the leakage of gas and harmful substances in the glove box is prevented; and has excellent high-voltage insulation and stable electrical transmission capability.
Currently, the sealing technique used on glove boxes is a common sealing technique, i.e. a sealing material, such as a sealing strip, a sealing ring or a sealant, is clamped between two sealing surfaces. The two sides of the sealing material are respectively ultra-high pure gas in the box body and air outside the box body, and the air with the oxygen concentration of more than 200000PPM is easily leaked into the glove box from a tiny gap, so that the purity of the gas in the box body is greatly influenced.
