蓄能罐式液控缓闭止回阀HVD74X(H)产品详细介绍： 5HVD74X(H)液控缓闭止回阀 Hydraulicco*oldumpingcheckbutterflyvalve 产品简述ProductInstruction: 凯丰液控缓闭止回蝶阀是目前国内外较*的管路控制设备，主要安装于水电水轮机进口，用作水轮机进口阀；或安装于水力、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，阀门于管道主机配合，按照水力过渡过程原理，通过预设的启闭程序，有效*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。
我公司生产的液控缓闭止回蝶阀流阻系数小、自动化程度高、功能齐全、性能稳定、使用寿命长，集国内外同类产品性能的基础上，引进阀门、液压、电气等行业的多项研究成果开发出来的新一代*智能化产品。
并根据用户特殊要求单独设计，满足广大用户对该产品的需求。
产品主要功能与特点:1、 可取代水泵出口处原电动闸阀和止回阀的功能，且机电系统集成一个整体，减少占地面积及基建投资。
2、 电液控制功能齐全，无需另外配置就可以作为一个独立的系统单机就地调试、控制；也可作为集散性控制系统（DNS）的个设备单元，通过I/O通道由中央计算机进行集中管理，于水泵水轮机、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，可控性能强。
电液控制系统设有多处调节点，可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，阀门能够且才能够按预先设置的时间、开启和分快、慢二阶段关闭。
并能实现无电关闭，有效*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*动，保障设备的安全可靠运行。
4、 采用三偏心金属密封或双偏心橡胶密封机构，启闭轻松、密封可靠：并有一道额外加大偏心，使阀门具有自关闭、自密封性能。
中、*碟版设计成流线型平板机构，大口径蝶阀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0.10.6，远小于止回阀门的流阻系数（1.7～2.6）调节性能明显。

手动泵用于系统调试和特殊工况下的阀门启闭。
液压系统电磁换向阀控制特征一般为正作用型，即：电磁阀的电蝶阀开关阀、失电蝶阀开关阀；反之为反作用型，即电磁阀失电蝶阀开阀、得电蝶阀开关阀。
常规配套电磁换向阀为正作用型，采用反作用型应在订货时说明。
液压系统与阀门本体可以是整体式安装，也可分开装。
用户未作特殊说明时为整体式安装。
蓄能器采用立体式布置时均为分体式安装。

按液压系统类别分为普通型、B型、S型、X型、XS型等，每类中又分为离心泵、轴流泵和水轮机等使用工况。
其中：开阀离心泵（含离心式混流泵）工况：先启动泵，延迟*时间后开阀，或泵阀同时启动。
开阀轴流泵（含轴流式混流泵）工况:先开阀至一定角度，再启动泵，或泵阀同时启动。
开阀水轮机工况；先开启旁通阀平衡压力，再开阀，后开启水轮机。
各种工况一般要求要在管道主机停机或控制回路和远程联动控制回路。
就地控制回路主要用于现场调试，正常工作时一般均使用远程联动控制回路。
系统动力电源为AC380V,控制电源可以AC220V,DC220V,DC110V或其他电源等级。
电液控制原理详细说明参数看我公司各类夜空蝶阀产品（安装使用说明书）用户订货时详细说明主逻辑元件类别、液压系统类别、管道主机联动方式，换向阀控制特征、控制电源等级等具体使用工况条件。
我公司可按用户的不同要求进行一定调整，并可根据用户特殊工况要求单独进行设计。
