Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0025] Such as Figure 1-Figure 3As shown, a high-precision water-blocking air pressure balance device has an outer shell 100 with a cavity formed inside and an adjustment assembly 200 arranged in the cavity of the outer shell 100. The adjustment assembly 200 includes a fixing member 210, a first adjustment piece 220 , a second adjusting piece 230 , a first elastic piece 240 and a second elastic piece 250 . The outer casing 100 and the adjustment assembly 200 are assembled to form a whole. In a specific implementation, the outer casing 100 can be made of an alloy material, which is cheap and easy to obtain. The fixing part 210, the first adjusting part 220 and the second adjusting part 230 in the adjusting assembly 200 can also be made of metal. The first elastic member 240 and the second elastic member 250 play a corresponding role through their own elasti...

Abstract

The invention discloses a high-precision water-blocking air pressure balance device, which comprises an outer casing with a cavity formed inside and an adjustment assembly arranged in the cavity of the outer casing, the adjustment assembly includes a fixing piece, a first adjustment piece, the second adjusting piece, the first elastic piece and the second elastic piece. The invention provides a brand-new device for internal and external ventilation during storage. By setting a diaphragm for water blocking, the problem caused by the high humidity of the external air is effectively solved. At the same time, the internal structure of the device is set to make it The operation is stable, the airflow is smooth, the action is sensitive, and the precision is high, which makes the device work well in actual use.

Description

technical field [0001] The invention relates to the technical field of air pressure adjustment, in particular to a high-precision water-blocking air pressure balance device. Background technique [0002] In various social business activities, warehousing is an indispensable link in the preservation and transportation of goods. Common ones include fresh goods storage, grain storage, ore powder storage, industrial semi-finished products such as forged steel storage and weapon storage, etc. [0003] The storage is inevitably affected by the surrounding environment. The common control indicators for the storage environment are the temperature and humidity of the item environment, as well as the concentration of oxygen and carbon dioxide. The reason is mainly related to chemical reactions such as rust. and biological responses to respiration, etc. In some warehouses, it is not necessary to maintain an inert gas environment. It is only necessary to maintain a normal gas exchange...
