重锤式自动保压液控缓闭蝶阀
 1. 产品简介 Introduction 液控缓闭蝶阀是目前国内外较先进的管路控制设备,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。
 The Hydraulic Contronl Slow-closing Butterfly Valve is one of advanced control equipment which installed at the intel of the turbine in the world, and it’s widely used as a out valve in irrigation works, power stations and various pump stations, replacing non-return valve and gate valve. While working, the valve cooperates with host computer of the pipeline, according to the transition course principle of water conservancy, through the procedure of opening and closing that is preserved, dispel the pipeline water hammer effectively, realize the ending reliably of the pipeline, and play a role in protecting systematic security of pipeline. 
本公司生产的液控缓闭蝶阀流阻系数小、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。
 The Hydraulic Contronl Slow-closing Butterfly Valve that our company produces features small flow resistence, high level of automation, multifarious functions, steady and reliable performance. The valve is a new generation's intelligent energy-efficient product, which designed by our company’s designers through collecting, studying, summarizing the domestic and international similar properties of product extensively, and introducing the multiple research results of the valve, hydraulic pressure, and electric trade. Our company's technical force is rich, and the special requirement that can follow users is designed alone, meet the masses of user's requirements for this kind of product diversely. 
该产品主要有如下特点:This product mainly has the following characteristic 
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。 It can replace the function of the electronic floodgate valve and the non-return valve, which are at the exit of the pump. The machine, electricity, liquid system integrates for one whole, as well as it can reduce floor space and capital expenditure.
 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I/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。 The electro-hydraulic control system has multifarious functions, and it can debug, control locally as an independent systematic unit without other additions. It also can be carried on centralized management by the central computer through I/O passway as a apparatus unit of the collecting and distributing control system (DCS), realize linking and operating with water pump, hydraulic turbine, by-pass valve and other pipelines apparatus. It is furnished with manual function, and can turn on, turn off the valve manually 重锤式自动保压液控缓闭蝶阀 4 without power, meet valve debugging, control request under the special operating mode. 
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逸事故的发生,降低管网系统的压力波动,保障设备的安全可靠运行。
 The controllability is good, the regulation range and adaptability is great. The electro-hydraulic control system has several regulation points. It can open and close the valve according to different pipeline control requests, so as to guarantee the valve shut-off and open automatically according to time, angle that set for in advance. In addition it can be closed without electricity, effectively dispel the destructive water hammer, prevent water pump and hydraulic turbine from splashing, reduce the pressure fluctuation of the pipe network system, guarantee equipment’s safe and reliable operation.
 4、 主阀密封副为三偏心金属密封结构,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、小口径蝶板设计成流线型平板结构,大口径蝶板设计面双平板桁架式结构,水流平顺,阀门流阻系数小,节能效果明显。
 The sealing pair of the main valve is triple-eccentric metal sealing structure. It is easy to open and close, and the sealing is reliable. It also has an extra enlarge eccentric which makes the valve has a good function of closing and sealing automatically. The disc of the middling and small calibre butterfly valve are designed with streamlined dull and stereotyped structure, heavy-calibre disc is designed with a pair of dull and stereotyped truss type structure, it is small to squeeze, the stream is smooth-going, The energy-conserving result is obvious.
