[0002] Nitrogen is a simple substance formed by nitrogen element, with the chemical formula N2. It is a colorless and odorless gas under normal temperature and pressure. It can only react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions, and can combine with oxygen to form nitric oxide under the condition of discharge; even active metals such as Ca, Mg, Sr and Ba can only react with it under heating conditions.

[0003] When protecting tobacco, it is necessary to fill nitrogen into the stack of tobacco, so that nitrogen gradually fills the entire tobacco stack from top to bottom, forming a high-nitrogen and low-oxygen environment to achieve the purpose of suffocating tobacco pests. When discharging nitrogen, a control joint is required. However, after the existing special control joint is used, it is not convenient to disassemble and tidy it up, resulting in longer time spent by the staff during operation. Therefore, there is an urgent need for a special control joint for filling nitrogen and adjusting gas to overcome the above defects. Content of the Utility Model
