摘要
介绍了CCFC型初撑自保阀的系统原理,指出了其不足之处,提出了用DCF-PZ200/40型初撑操纵阀可以有效地使立柱活塞腔内液体压力达到额定初撑力。
System theory of CCFC type setting guaranteed valve was introduced ,whose defect was indicated. And then the paper put forward DCF-PZ200/40 type setting guaranteed operating valve which could availably make the pressure of leg piston cavity achieve rating setting load.
