1.產品簡介Introduction
  
液控緩閉止回蝶閥是目前國內外較先進的管路控制設備，主要安裝于水利、電力、給排水等各類泵站的水泵出口，替代止回閥和閘閥的功能。工作時，閥門與管道主機配合，按照水力過渡過程原理，通過預設的啟閉程序，有效消除管路水錘，實現管路的可靠截止，起到保護管路系統安全的作用。
The Hydraulic Control Slow-closing Butterfly Valve is one of advanced control equipment which is 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.
本公司生產的液控緩閉止回蝶閥流阻系數小、自動化程度高、功能齊全、性能穩定可靠，是我公司設計人員在廣泛搜集、研究、總結國內外同類產品性能的基礎上，引入閥門、液壓、電氣等行業的多項研究成果，厚積而薄發，開發出來的新一代智能化高效節能產品。公司技術力量雄厚，并可根據用戶的特殊要求單獨進行設計，多方位滿足廣大用戶對該類產品的需要。
The Hydraulic Control Slow-closing Butterfly Valve that our company produces features small flow resistance, 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.
該產品主要有如下特點：
This product mainly has the following characteristic
1、可取代水泵出口處原電動閘閥和止回閥的功能，并把機、電、液系統集成為一個整體，減少占地面積及基建投資。
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、電液控制功能齊全，無需另外配置即可以作為一個獨立的系統單機就地調試、控制；也可以作為集散性控制系統（DCS）的一個設備單元，通過I/O通道由中央計算機進行集中管理，與水泵、及其他管道設備實現聯動操作；并配有手動功能，無動力電源時也可以實現手動開、關閥，滿足特殊工況下的閥門調試、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 pass way 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 without power, meet valve debugging, control request under the special operating mode.
3、可控性好，調節范圍大、適應性強。電液控制系統設有多處調節點，可以按不同的管道控制要求進行啟閉程序設置，保證在滿足開、關閥條件時，閥門能夠自動按預先設定的時間、角度開啟和分快關、慢關兩階段。并能實現無電關閥，有效消除破壞性水錘，防止水泵和水輪機組飛逸事故的發生，降低管網系統的壓力波動，保障設備的安全可靠運行。
     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, the pressure fluctuation of the pipe network system, guarantee equipment’s safe and reliable operation.
4、主閥密封副為三偏心金屬密封或雙偏心橡膠密封結構，啟閉輕松、密封可靠；并有一道額外加大的偏心，使閥門具有良好的自關閉、自密封性能。中、小口徑蝶板設計成流線型平板結構，大口徑蝶板設計面雙平板桁架式結構，水流平順，閥門流阻系數小，節能效果明顯。
The sealing pair of the main valve is triple-eccentric metal sealing or double-eccentric rubbery 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.
