【 A42Y彈簧全啟式安全閥用途】
A42Y彈簧全啟式安全閥采用全封閉閥蓋和閥帽結(jié)構(gòu),安全閥開啟排放時(shí),介質(zhì)不會(huì)向外界泄漏,而全部通過排泄管排掉,又可防止灰塵等雜質(zhì)進(jìn)入閥內(nèi),適用于溫度不高于300度的氣體和需要大排量的液體介質(zhì)。
【A42Y彈簧全啟式全閥特點(diǎn)】
1.全啟式結(jié)構(gòu),排量大
2.閥瓣處設(shè)有反沖盤部件
3.平面結(jié)構(gòu)的閥瓣和閥座易于維修和重新加工
4.整定壓力偏差小,可達(dá)±3%
5.選用優(yōu)質(zhì)的彈簧鋼,保證彈簧的壽命和穩(wěn)定性
