現(xiàn)如今電動(dòng)執(zhí)行器和閥門電動(dòng)裝置已被廣泛作用于各行各業(yè)，那么電動(dòng)執(zhí)行器的發(fā)展歷史是怎樣的呢？天蝶閥門小編帶您來了解一下吧！

簡述電動(dòng)執(zhí)行器及閥門電動(dòng)裝置的組成

The development history of valve electric device and the composition of valve electric device are briefly introduced

自1929年LIMITORQUE制造出了世界上臺(tái)閥門電動(dòng)裝置以來，電動(dòng)執(zhí)行器獲得了較快的發(fā)展．國外是將電動(dòng)執(zhí)行機(jī)構(gòu)與電動(dòng)裝置視為同一類產(chǎn)品，分別應(yīng)用于閉環(huán)控制系統(tǒng)和開環(huán)控制系統(tǒng)。閥門電動(dòng)裝置在國內(nèi)電力、冶金、石油化工、污水處理及市政等各個(gè)行業(yè)得到應(yīng)用。與其他閥門驅(qū)動(dòng)裝置相比，電動(dòng)驅(qū)動(dòng)裝置具有動(dòng)力源廣泛，操作迅速、方便等特點(diǎn)，并且容易滿足各種控制要求。所以，在閥門驅(qū)動(dòng)裝置中，電動(dòng)裝置占主導(dǎo)地位。

Since 1929, LIMITORQUE has produced the world's first valve electric device, the valve electric device has been developed rapidly the construction and the electric device are regarded as the same kind of products, which are respectively applied to the closed loop control system and the open-loop control system. Valve electric device in the domestic electric power, metallurgy, petrochemical, sewage treatment and municipal and other industries have been applied.Compared with other valve drive devices, electric drive device has a wide range of power sources, rapid operation, convenience, and easy to meet various control requirements.Therefore, in the valve drive, electric devices dominate.

用戶的需求是多種多樣的，有希望帶控制的、帶無線遙控的、帶狀態(tài)顯示的、帶總線通訊等。現(xiàn)場的工況條件千差萬別，如長期潛水、抗輻射、抗震動(dòng)、耐高溫、耐腐蝕、防爆等。總體上閥門電動(dòng)裝置的發(fā)展正按照用戶需求、工況條件朝著高智能型、高可靠性兩個(gè)方向發(fā)展：

The user's needs are diverse, there is hope with control, with wireless remote control, with state display, with bus communications.The work-ing conditions on site vary widely, such as long-term diving, anti-radiation, anti-vibration, high temperature, corrosion resistance, explosion-proof and so on.On the whole, the development of the valve electric device is developing in two directions, that is, high intelligence and high reliability according to the user's demand and work-ing condition:

一是隨著電力電子技術(shù)、計(jì)算機(jī)技術(shù)及通訊技術(shù)的快速發(fā)展，單片機(jī)和新型高速微處理器代替以模擬電子器件為主的閥門電動(dòng)裝置控制單元，閥門電動(dòng)裝置正朝著高智能型方向快速發(fā)展，功能越來越強(qiáng)大。適合一般現(xiàn)場工況環(huán)境，操作和控制越來越方便。

First, with the rapid development of power electronic technology, computer technology and communication technology, MCU and new high speed microprocessor are the main substitutes for analog electronic devices valve electric device control unit, valve electric device is moving in the direction of rapid development of high intelligence, more and more powerful.It is more and more convenient to operate and control for general work-ing conditions.

二是為適應(yīng)特殊行業(yè)的惡劣工況環(huán)境，這些場合往往對(duì)閥門電動(dòng)裝置自身控制的要求不高，但特別強(qiáng)調(diào)高可靠性，通過特殊的機(jī)械結(jié)構(gòu)設(shè)計(jì)和材料選用，經(jīng)過嚴(yán)酷的試驗(yàn)測試．使閥門電動(dòng)裝置正朝著高可靠性方向發(fā)展。

Second, in order to adapt to the harsh work-ing conditions of special industries, these occasions often do not have high requirements for the self-control of valve electric devices.But special emphasis on high reliability, through the special mechanical structure design and material selection, after rigorous test tests, so that the valve electric device is moving toward high reliability direction. 

電動(dòng)閥門一般是由給排水專業(yè)選型的，給排水專業(yè)技術(shù)人員在工程設(shè)計(jì)時(shí)須對(duì)閥門的電動(dòng)裝置提出具體的功能要求，并由專業(yè)制造廠商對(duì)電動(dòng)裝置進(jìn)行選型。然而，在實(shí)際工程中經(jīng)常會(huì)發(fā)生在現(xiàn)場安裝時(shí)，閥門電動(dòng)驅(qū)動(dòng)裝置與控制系統(tǒng)沖突等不匹配的現(xiàn)象。這通常是由于在確定電動(dòng)裝置的功能需求時(shí)有不合理或是不完善的地方。

Electric valves are generally selected by the professional water supply and drainage, water supply and drainage professional and technical personnel in the engineering design of the electric device to the valve to put forward specific functional requirements, and by the professional manufacturers of electric devices selection.However, in the practical engineering, there is often a mismatch between the electric drive of the valve and the control system when it is installed on the site. This is usually due to unreasonable or imperfect aspects in determining the functional requirements of an electric device.

閥門電動(dòng)裝置的組成一般由下列部分組成：電動(dòng)機(jī)減速機(jī)構(gòu)，用以降低電動(dòng)機(jī)的輸出轉(zhuǎn)速；行程控制機(jī)構(gòu)，用以調(diào)節(jié)和準(zhǔn)確控制閥門的啟閉位置；轉(zhuǎn)矩限制機(jī)構(gòu)，用以調(diào)節(jié)轉(zhuǎn)矩（或推力）并使之不超過預(yù)定值；手動(dòng)、電動(dòng)切換機(jī)構(gòu)，進(jìn)行手動(dòng)或電動(dòng)操作的聯(lián)鎖機(jī)構(gòu)；開度指示器，用以顯示閥門在啟閉過程中所處的位置。其中，行程控制機(jī)構(gòu)、轉(zhuǎn)矩限制機(jī)構(gòu)、手動(dòng)、電動(dòng)切換機(jī)構(gòu)及開度指示器等合稱為電動(dòng)執(zhí)行器。

The stroke control mechanism is used for adjusting and accurately controlling the opening and closing position of the valve;a torque limiting mechanism for adjusting the torque (or thrust) so that it does not exceed a predetermined value;manual, electric switching mechanism, manual or electric operation of the interlock mechanism;the opening indicator is used to show the position of the valve in the opening and closing process. The stroke control mechanism, the torque limiting mechanism, the manual, the electric switching mechanism and the opening indicator are collectively referred to as electric actuators.
