    Description:
    系列 Series
    先导式安全泄压阀是一种新颖结构的安全阀。主要用于石油天然气、化工、电力、冶金和城市燃气等领域,是受压设备、容器或管路上的最佳超压保护装置。其主要优点是变弹簧直接作用为导阀间接作用,提高了动作的灵敏度,而且主阀采用套筒活塞式,双重密封阀座结构,动作精度高、重复性好、回座快、不泄漏、能带高背压排放、工作寿命长、工作稳定可靠,它还可在线调校,反复启跳排放后,仍然能自动回座,关闭严密,操作维护方便。
    Pilot operated safety valve,newly-structured, is mainly applied to such trades as petroleum & nat-ural gas, chemistry, electric, meta-llurgy & burning gas. It is the best super-pressure protecting equipment on press equipment, container, or pipeline, It is mainly characterized by shifting direct function of spring to indirect function of guide valve. What's more, main valve, applying for sleeve piston & double sealed seat, is characterized by high pre-cision of action, good recycling function, fast turning back to seat, ability to high-pressure leaking, long working time & security, toge-ther with read-justment on line,
    aucomatic turning back to seat after leaking again and again, tight closure, operating and main-taining conve-nience.
