Embodiment 1

[0017] A simple constant pressure glove box, such as figure 1 As shown, it includes a box body 1, a glove port 2 for operation, an inert gas source 3 connected to the box body 1, and an operation door 4 is installed on the side of the box body 1, and the operation door 4 is connected to the side of the box body 1. The edge of the contact surface is provided with a magnetic material 5 and a sealing ring. The operation door 4 and the box body 1 are locked by a mechanical lock, and the operation door 4 and the box body 1 are sucked tightly by the magnetic material 5. The magnetic material 5 The magnetic attraction force is 0.2MPa; the top of the operation door 4 is fixed on the side of the box body 1 through a pin shaft; the magnetic material 5 is a magnetic bar, and the magnetic bar is installed on the side of the operation door 4 A door edge and a position corresponding to the door edge on the box body 1 .

[0018] When an experiment is needed, the box body 1 is inflated throu...

Embodiment 2

[0020] The same function can also be realized by replacing the operation door 4 in the above-mentioned embodiment with an air overflow valve, and also can add other equipment behind the air overflow valve, such as gas recovery, etc., so that a greater Energy saving and environmental protection.

[0021] The box body 1 is made of plexiglass, and its compressive strength is greater than 0.4MPa. Such a box body ensures the pressure environment of the gas.

Abstract

The invention is applied to operations in a lab or a plant which requires an inert gas atmosphere and specifically relates to a simple constant-pressure glove box which comprises a box body, glove holes used for the operations and an inert gas source communicated with the box body, wherein an operation door is installed on the side face of the box body, a magnetic material and a sealing ring are disposed on edges of the contact face between the operation door and the box body, the operation door and the box body are locked by a mechanical lock, and the operation door and the box body are sucked tightly by the magnetic material. By virtue of absorption of the magnetic material with a certain intensity, a magnetic absorption door is disposed on the glove box, so that an automatic pressure adjustment function can be realized. The simple constant-pressure glove box is simple and practical, maintains a constant-pressure and high-purity gas environment in the box body and is also low in cost.

Description

technical field [0001] The invention is applied to laboratories and factories that need to be operated under an inert gas atmosphere, and in particular relates to a simple constant pressure glove box. Background technique [0002] Modern laboratories and processing centers often need to use high-purity gases and high-purity materials for more complex modern fine processing and production, such as some large-scale analytical instruments (inductively coupled plasma mass spectrometry, laser ablation technology, inductively coupled plasma emission spectroscopy, etc. ) can achieve ultra-low content (less than 10-9μg / g) element content analysis, and some multi-receiver mass spectrometers can achieve high-precision ratio analysis of low content elements, such as lead, strontium, neodymium, hafnium and other isotope composition analysis . The analysis of these elements and isotopes requires a lower instrument blank, that is, the background of the corresponding elements and isotopes...
