一、先導(dǎo)式安全閥概述:
先導(dǎo)式安全泄壓閥是一種新穎結(jié)構(gòu)的安全閥。主要用于石油天然氣、化工、電力、冶金和城市燃?xì)獾阮I(lǐng)域,是受壓設(shè)備、容器或管路上的超壓保護(hù)裝置。其主要優(yōu)點是變彈簧直接作用為導(dǎo)閥間接作用,提高了動作的靈敏度,而且主閥采用套筒活塞式,雙重密封閥座結(jié)構(gòu),動作精度高、重復(fù)性好、回座快、不泄漏、能帶高背壓排放、工作等命長、工作穩(wěn)定可靠,它還可在線調(diào)校,反復(fù)啟跳排放后,仍然能自動回座,關(guān)閉嚴(yán)密,操作維護(hù)方便。
