Abstract

The invention particularly relates to a miniature nitrogen-filled airtight vacuum control device which solves the problems that existing nitrogen-filled airtight vacuum equipment is large in size, high in cost and complex in structure. The miniature nitrogen-filled airtight vacuum control device includes a mounting base, a ventilation channel is formed in the mounting base; a nitrogen adapter is arranged in front of the ventilation channel and extends out of the mounting base; a nitrogen charging valve is arranged at the nitrogen adapter, a vacuum adapter is arranged in front of the ventilation channel and extends out of the mounting base, a vacuum valve is arranged at the vacuum adapter, a product adapter is arranged behind the ventilation channel and extends out of the mounting base, a pressure vacuum gauge is arranged above the ventilation channel of the product adapter, and an exhaust valve is arranged at the right end of the ventilation channel. The device is simple in structure,reliable in control, convenient to operate, carry and maintain, wide in application field, high in cost performance and high in practical value.

Description

technical field [0001] The invention relates to airtight vacuum equipment, in particular to a miniature nitrogen-filled airtight vacuum control device. Background technique [0002] In the military and civilian fields, it is necessary to test the airtightness of the airtight compartment of the equipment. At the same time, in order to ensure that the electronic components and metal structural parts in the airtight chamber are not oxidized, it needs to be filled with inert gas for protection. Currently, the existing equipment includes the following: disadvantages: [0003] 1) It is bulky, takes up space, and is inconvenient to move. [0004] 2) High cost and low cost performance. [0005] 3) The structure is more complex and inconvenient to maintain. Contents of the invention [0006] In order to solve the problems of large volume, high cost and complex structure of the existing nitrogen-filled airtight vacuum equipment, the invention provides a miniature nitrogen-filled ...
