Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only Some, but not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] Such as figure 1 As shown, the embodiment of the present invention provides an air pressure regulating chamber 1, which is applied to a sealed box. The air pressure regulating chamber 1 is arranged outside the sealed box. The sealed box includes a main box body 2 and a first A valve 3, the air pressure regulating chamber 1 communicates with and / or cuts off the ...

Abstract

The invention discloses an air pressure adjusting chamber which is applied to a sealing box. The air pressure adjusting chamber is arranged outside the sealing box; the sealing box comprises a main box body and first valves arranged on face plates of the main box body; the air pressure adjusting chamber communicates with and / or is separated from the main box body through the first valves; the airpressure adjusting chamber comprises a shell and a pressure adjusting valve arranged in the shell; and the pressure adjusting valve is used for communicating with the outside world to adjust the pressure in the interior of the air pressure adjusting chamber. The invention also discloses the sealing box with the air pressure adjusting chamber. According to the air pressure adjusting chamber and thesealing box with the same, the air pressure adjusting chamber is arranged on the sealing box, the purity degree of gas in an operating space of the sealing box is ensured, the leakage and invasion ofexternal substances possibly caused by the existence of gaps or the fine diffusion is effectively cut off, water and oxygen impurities in the sealing box are kept below 1PPM, and the purity and the pressure intensity of the gas in the sealing box are effectively controlled.

Description

technical field [0001] The invention relates to the technical field of glove boxes, in particular to an air pressure regulating chamber and a sealed box having the same. Background technique [0002] A sealed box is a box made of metal, glass or plastic. The main box has multiple openings for fittings such as windows, transition chambers and glove ports. The operator uses gloves to operate the materials and equipment in the box to meet the requirements of isolating one or several active components in the air such as oxygen, moisture, carbon dioxide and other sensitive components in the scientific research and production process to achieve airtight operating within the environment. [0003] At present, all airtight boxes have the problem of air leakage. Even if a airtight box is filled with high-purity gas, it is difficult to make the water and oxygen impurity contents inside each less than 1PPM (part per million). During normal use, water and oxygen will continue to rise g...
