液控缓闭止回蝶阀是目前国内外较先进的管理控制设备，主要安装于水电站水轮机进口，用作水轮机进口阀；或安装于水利、电力、给排水等各类泵站的水泵出口，替代止回阀和闸阀的功能。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。

本公司生产的液控缓闭止回蝶阀流阻系数小、智能化程度高、功能齐全、性能稳定可靠，是我公司设计人员在广泛搜集、研究、总结国内外同类产品性能的基础上，引入阀门、液压、电气等行业的多项研究成果，厚积而薄发，开发出来的新一代智能化高效节能产品。公司技术力量雄厚，并可根据用户的特殊要求单独进行设计，多方位满足广大用户对该类产品的需要。

该产品主要有如下特点：

1、可取代水泵出口处原电动闸阀和止回阀的功能，且机、电、液系统集成为一个整体，减少占地面积及基建投资。

2、电液控制功能齐全，无需另外配置即可以作为一个独立的系统单机就地调试、控制：也可以作为集散性控制系统(DCS）的一个设备单元，通过/O通道由中央计算机进行集中管理，与水泵、水轮机、旁通阀及其他管道设备实现联动操作；并配有手动功能，无动力电源时也可以实现手动开、关阀，满足特殊工况下的阀门调试、控制要求。

3、可控性好，调节范围大、适应性强。电液控制系统设有多处调节点，可以按不同的管道控制要求进行启闭程序设置，保证在满足开、关阀条件时，阀门能够且才能够自动按预先设定的时间、角度开启和分快、慢二阶段关闭。并能实现无电关阀，有效消除破坏性水锤，防止水泵和水轮机组飞过事故的发生，降低管网系统的压力波动，保障设备的安全可靠运行。

4、主阀密封副为三偏心金属或双偏心橡胶密封结构，启闭轻松、密封可靠；并有一道额外加大的偏心，使阀门具有良好的自关闭、自密封性能。中、小口径蝶板设计面双平板桁架式结构，排挤小、水流平顺，阀门流阻系数仅为0.1-0.6，远小于止回阀的流阻系数（1.7-2.6），节能效果明显。

本止回阀是一种三偏心结构助关缓闭蝶形止回阀，带辅助气动装置及缓闭阻尼油缸，适用于工作温度<300℃，瞬时温度不超过350℃的空气、可燃性气体、水等介质的管道。阀门的开启主要由阀前阀后的压差实现，而阀门的关闭则依靠阀瓣的自重及重锤的作用来自动关闭大部分，由气压来完成最终的关闭。阻尼油缸起到缓冲、阻尼作用，由于采用三偏心蝶形结构，阀瓣在启闭过程中缩短了相对摩擦时间，从而延长阀门的使用寿命和密封性能，而阻尼油缸可减少关闭过程中的冲击，消除压力波引起的振动，同时延长阀门的使用寿命。

该产品在一般情况下，水中约含2VOL%的溶解空气，在输水过程中，这些空气由水中不断释放出来，聚集在管线的高点处，形成空气袋（AIRPOCKET），使输水变得困难，系统输水能力可因此下降约5 - 5 % 。此微量排气阀主要功能就是排除这2VOL%的溶解空气，并适合装置于高层建筑，厂区内配管，小型泵站用以保护或改善系统的输水效率及节约能源。

单杆式（SIMPLELEVERTYPE）微量排气阀，为一类似椭圆形阀体，内部所有零件包括浮球，杠杆、阀座等均为304不锈钢，内部使用标准排气孔径1/6，适合用于PN16工作压力环境。介质温度：0-80℃。

AVAX型自动排气阀主要应用于暖通空调系统，往往安装在制高点或弯头等处，以排除管道中多余气体、提高管路使用效率及降低能耗。介质温度：0\~80℃。

该产品由内壳、高级合成橡胶性内胆及多孔管等组成。适用于工矿、企业、高层建筑、电站等各类给排水泵统中。在无需阻止水流的条件下，具有超卓的水击吸收力，有效地吸纳水锤。

ZYA-9000型活塞式气囊式水锤吸纳器的内部有一密闭的容气腔，下端为一活塞。当冲击波传入水锤吸纳器时，水击波作用于活塞上，活塞将往容气腔方向运动，活塞在一定压力的气体和不规则水击波双重作用下做上下运动，形成一个动态的平衡，这样就消除了不规则的水击波震荡。
