液控止回偏心半球阀 液控图阀门零件图

工作时，阀门与管道主机配合，按照水力过渡过程原理，通过预设的启闭程序，有效消除管路水锤，实现管路的可靠截止，起到保护管路系统安全的作用。液控止回阀适用于介质为水的泵出口管路上，作为闭路止回阀，用来避免和减少管路系统中介质倒流，防止产生过大的水锤，以保护管路系统。蓄能罐式液控闭止回蝶阀是在消化吸收欧美液控阀门基础上研制而成的新型产品。目前该阀门是我国一代液控蝶阀，它兼有闸阀和止回阀的功能，是一种能按预先调定的程序，分两阶段（先快关一定角度，再慢速关闭剩余角度）关闭的动作来消除水锥对管网破坏的理想控制设备。蓄能式液控缓闭止回蝶阀、重锤式液控缓闭止回蝶阀、液控止回偏心半球阀、液控快速关闭阀、液控截止阀、液控闸阀水轮机进水液控球阀，液控阀门，液控执行器，大口径全通径偏心半球阀 双向硬碰硬旋球阀 电动阀门，气动阀门及控制阀门液压站，高压液控截止阀，气液联动球阀，液控阀门控制装置。重锤式液控阀门，蓄能式液控阀门，重锤蓄能冗型液控阀，0.5秒快切阀门，快关、快开调节阀，阀门电控箱。
