全啟式安全閥概述：
博通閥門是國內(nèi)生產(chǎn)安全閥的主導(dǎo)廠，廠內(nèi)建有遠(yuǎn)東*的安全閥測試中心，國產(chǎn)*臺安全閥就是我廠誕生的。二十多年來，博通閥門產(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)*座核電站秦山核電站研制成功了*批核級安全閥。博通閥門安全閥主要產(chǎn)品系列分別榮獲機械部信得過產(chǎn)品，博通閥門是受壓設(shè)備、容器或管路上的*超壓保護裝置。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。博通閥門是選用者為保護工程設(shè)備安全運行的的，zui科學(xué)的明智選擇。
