衛生級制藥用米勒緊急泄壓人孔生產廠家

緊急泄壓人孔工作原理：

在阻火呼吸閥正常工作情況下，呼吸人孔,阻火緊急放空人孔基本保持密封狀態，儲罐處于正常壓力。當呼吸閥正常工作滿足不了因意外原因造成儲罐急劇超壓時，呼吸人孔的泄壓蓋自動頂開，進行緊急泄壓，使罐內壓力保持正常；當罐內壓力急劇減壓或超真空時，吸入閥便開啟急劇吸入大氣，維護罐內正常壓力；當吸入大氣帶有火花、火焰時，阻火層起到“器壁效應"的作用來阻止火焰的通過，以保護儲罐的安全。

緊急泄壓人孔介紹：
阻火緊急放空人孔是安裝在石油、化工等物料儲罐上的安全應急通風裝置，通常與阻火呼吸閥配套使用，既能避免因意外原因造成罐內急劇超壓或真空時，損壞儲罐而發生的事故；又能起到安全阻火作用。
是目前國內保護儲罐安全的理想裝置。 產品采用全天候密封結構，以配重來調節吸入閥瓣和泄壓蓋的開閉，以不銹鋼波紋帶為阻火層，來阻止火焰的通過，并設雙抽屜口，為清洗更換阻火層提供了方便，縮短了時間。總之，該產品具有定壓排放、定壓吸入、工閉靈活、安全阻火、結構緊湊、密封性能好、安全可靠等優點。

Emergency relief manhole working principle: in the normal operation of the fire-resistant breathing valve, breathing manhole, fire-resistant emergency relief manhole basically keep sealed state, storage tank at normal pressure. When the normal operation of the breathing valve can not satisfy the sudden overpressure of the tank caused by accident, the pressure relief cover of the breathing manhole automatically opens to carry out emergency pressure relief so as to keep the pressure in the tank normal When the pressure inside the tank is sharply reduced or the super vacuum occurs, the suction valve opens to sharply inhale the atmosphere to maintain the normal pressure inside the tank, the fire-retardant layer acts as a“Wall effect" to prevent the flame from passing through and protect the safety of the storage tank. Emergency Relief Manhole: fire-resistant emergency relief manhole is installed in the oil, chemical and other materials storage tanks on the safety of emergency ventilation device, usually used with fire-resistant breathing valve, it can not only avoid the accident caused by sudden overpressure or vacuum in the tank, but also play the role of fire safety. It is an ideal device for protecting the safety of storage tanks in China. The product adopts all-weather sealing structure, adjusts the opening and closing of the suction disc and pressure relief cover with counterweight, uses the stainless steel corrugated belt as the fire-proof layer to prevent the flame from passing through, and sets the double drawer mouth, the utility model provides convenience for cleaning and replacing the fire-retardant layer and shortens the time. In a word, the product has the advantages of constant pressure discharge, constant pressure inhalation, flexible working closure, fire-resistant safety, compact structure, good sealing performance, safety and reliability.
