微啟式安全閥概述：
國內(nèi)生產(chǎn)安全閥的主導(dǎo)廠，廠內(nèi)建有遠(yuǎn)東{yl}的安全閥測試中心，國產(chǎn){dy}臺安全閥就是我廠誕生的。二十多年來，安全閥的品種已發(fā)展到百余個系列，千余個規(guī)格，產(chǎn)品廣泛應(yīng)用于鍋爐、石化、電站以及國防工業(yè)。并為國內(nèi){dy}座核電站秦山核電站研制成功了{(lán)dy}批核級安全閥。 安全閥主要產(chǎn)品系列分別榮獲機(jī)械部信得過產(chǎn)品，上海市優(yōu)質(zhì)產(chǎn)品稱號，國家銀質(zhì)獎。 安全閥是受壓設(shè)備、容器或管路上的{zj0}超壓保護(hù)裝置。當(dāng)設(shè)備壓力升高達(dá)到預(yù)定值時，安全閥自動開啟，繼而全量排放，防止設(shè)備壓力繼續(xù)升高；當(dāng)壓力降低到規(guī)定值時，安全閥及時自動關(guān)閉。安全閥是選用者為保護(hù)工程設(shè)備安全運行的最理想的，最科學(xué)的明智選擇。
