詳細(xì)介紹
一、產(chǎn)品簡(jiǎn)介
A42H-C型彈簧全啟封閉式安全閥適用于工作溫度≤300℃的空氣、石油氣、液體等介質(zhì)的設(shè)備或管路上;A42Y-P/R型適用于工作溫度≤200℃有腐蝕性介質(zhì)的設(shè)備和管路上,作為超壓保護(hù)裝置。
二、產(chǎn)品概述:
A42H-C型彈簧全啟封閉式安全閥適用于工作溫度≤300℃的空氣、石油氣、液體等介質(zhì)的設(shè)備或管路上;A42Y-P/R型適用于工作溫度≤200℃有腐蝕性介質(zhì)的設(shè)備和管路上,作為超壓保護(hù)裝置。當(dāng)設(shè)備或管道內(nèi)壓力超過允許值時(shí),閥門自動(dòng)開啟,繼而全量排放,當(dāng)壓力降至規(guī)定值時(shí),閥門自動(dòng)關(guān)閉,保證設(shè)備和管道的安全運(yùn)行。
