泄壓人孔

泄壓人孔 Pressure relief manhole

泄壓人孔是迅速泄壓設備，其技能功能、首要零部件資料與呼吸人孔一樣。
The pressure relief manhole is a rapid pressure relief equipment, and its skills, functions and primary components are the same as those of the breathing manholes.

泄壓人孔是是裝置在石油化工等設備和儲罐上的安全應急通風設備，一般與罐頂上裝置的呼吸閥配套運用，堅持罐內的正常壓力，既能防止因意外因素形成罐內急劇超壓或真空時，損壞儲罐而發作的事端；
The pressure relief manhole is safety emergency ventilation equipment device in petrochemical equipment and storage tanks, and the top of the tank for the breathing valve supporting the use of, adhere to the normal pressure tank, which can prevent the formation of accidental factors of tank sharp overpressure or vacuum, damaged tanks and attack incidents;

泄壓人孔具有定壓排放、定壓吸入、式閉靈敏、構造緊湊、密封功能好、安全可靠等長處。
The pressure relief manhole has many advantages, such as constant pressure discharge, constant pressure suction, closed type sensitivity, compact structure, good sealing function, safety and reliability.
