安全回流閥適用于工作溫度-40~+80℃液化石油氣泵出口的液相回流管道上,用于超壓介質(zhì)的安全回流,當(dāng)泵前壓力超過規(guī)定值時,閥門自動開啟,并起安全回流入罐,能保證設(shè)備和管路的安全運(yùn)行。
產(chǎn)品工作原理和用途:
安全回流閥適用于工作溫度-40~+80℃液化石油氣泵出口的液相回流管道上,用于超壓介質(zhì)的安全回流,當(dāng)泵前壓力超過規(guī)定值時,閥門自動開啟,并起安全回流入罐,能保證設(shè)備和管路的安全運(yùn)行。
AH42F、A42F液化石油氣安全閥、安全回流閥安裝在管道上和貯罐、球罐上,保護(hù)設(shè)備內(nèi)介質(zhì)壓力異常升高到規(guī)定值時。閥門自動開啟,繼而全量排放,起到保護(hù)設(shè)備安全的作用。適用于大多數(shù)的固定球罐上。
產(chǎn)品結(jié)構(gòu)特點(diǎn):
一旦系統(tǒng)管路或裝置中的介質(zhì)壓力超過設(shè)定值,會自動釋放壓力,從而達(dá)到安全保護(hù)的目的。
主要參數(shù)是排量,這個排量決定于閥座的口徑和閥瓣的開啟高度,由開啟高度不同,又分為微啟式和全啟式兩種。
