VA-7010系列電動二通閥是專供中央空調(diào)風機盤管的配套產(chǎn)品，由驅動器與閥體兩部分組成，驅動器由一個磁滯同步電機驅動，具備彈簧復位及手動開閥杠桿操縱功能。閥體部分采用活塞式結構。電動閥可與溫控器配套使用，由溫控器控制電動閥電機，使閥門打開或關閉，實現(xiàn)管道冷水或熱水的通或斷，再通過風機盤管送風，以實現(xiàn)溫度的自動調(diào)節(jié)。工作原理：驅動器由單向磁滯同步電機驅動，閥門彈簧復位，閥門不工作時處于常閉狀態(tài).當房間溫度發(fā)生變化時，由溫控器提供一個交流電源開啟信號，使單向磁滯同步電機接通交流電源而動作，通過齒輪傳動推動活塞式結構閥體開啟閥門，冷凍水或熱水進入風機盤管，為房間提供冷氣或暖氣.當室溫達到溫控器設定值時，溫控器令電動閥斷電，復位彈簧使閥門關閉，從而截斷進入風機盤管的水流，通過閥門關閉和開啟，使室溫始終保持在溫控設定的溫度范圍。 主要技術參數(shù):1、電源電壓：220/110/24 10%V，50～60Hz；2、環(huán)境溫度：0～65 max；3、流通介質：空調(diào)冷熱水；4、功率消耗：＜6W；5、流體溫度：0～95℃；6、開關閥時間：通電后7秒內(nèi)；7、閥體承壓：1.6Mpa；8、驅動器馬達類別：磁滯同步電機。MotorizedTwo-wayValveVA-7010SeriesMotorizedTwo-wayValve,consistingofvalvebodyandactuatordrivenbyhysteresismotor, arespeciallycoupled withfancoilofcommercialairconditionerstocontrolthemedium(hotorcoldwater)inthecoilthrougharoomthermostat.Asaresult,itcanachieveautomatictemperaturecontrol.Whenpoweron,actuatorstartedbysynchronoushysteresismotoropenvalve,andwhenpoweroff,springreturnclosevalve.Valveisclosedoffwhenitisnotinuse.Whentheroomtemperatureisaboveorbelowtheset-point,thermostatsendapowersignaltoactuatorthatwillconnecttopower,openvalve,inputhotwaterorchilledwatertofancoilunit.Bydoingthis,thecoolingorheatingairwillbeprovidedtotheroom.Whentheroomtemperaturereachedtheset-point,thermostatcutoffpower,motorizedvalvecloses,springswitchreturns,thehotwaterorchilledwaterisblockedinfancoilunit.Byvalveopeningandclosing,theroomtemperaturecanbemaintainedattheset-point.
