VA-7010系列電動(dòng)二通閥是專供中央空調(diào)風(fēng)機(jī)盤管的配套產(chǎn)品，由驅(qū)動(dòng)器與閥體兩部分組成，驅(qū)動(dòng)器由一個(gè)磁滯同步電機(jī)驅(qū)動(dòng)，具備彈簧復(fù)位及手動(dòng)開閥杠桿操縱功能。閥體部分采用活塞式結(jié)構(gòu)。電動(dòng)閥可與溫控器配套使用，由溫控器控制電動(dòng)閥電機(jī)，使閥門打開或關(guān)閉，實(shí)現(xiàn)管道冷水或熱水的通或斷，再通過風(fēng)機(jī)盤管送風(fēng)，以實(shí)現(xiàn)溫度的自動(dòng)調(diào)節(jié)。工作原理：驅(qū)動(dòng)器由單向磁滯同步電機(jī)驅(qū)動(dòng)，閥門彈簧復(fù)位，閥門不工作時(shí)處于常閉狀態(tài).當(dāng)房間溫度發(fā)生變化時(shí)，由溫控器提供一個(gè)交流電源開啟信號，使單向磁滯同步電機(jī)接通交流電源而動(dòng)作，通過齒輪傳動(dòng)推動(dòng)活塞式結(jié)構(gòu)閥體開啟閥門，冷凍水或熱水進(jìn)入風(fēng)機(jī)盤管，為房間提供冷氣或暖氣.當(dāng)室溫達(dá)到溫控器設(shè)定值時(shí)，溫控器令電動(dòng)閥斷電，復(fù)位彈簧使閥門關(guān)閉，從而截?cái)噙M(jìn)入風(fēng)機(jī)盤管的水流，通過閥門關(guān)閉和開啟，使室溫始終保持在溫控設(shè)定的溫度范圍。 主要技術(shù)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(zhì)：空調(diào)冷熱水；4、功率消耗：＜6W；5、流體溫度：0～95℃；6、開關(guān)閥時(shí)間：通電后7秒內(nèi)；7、閥體承壓：1.6Mpa；8、驅(qū)動(dòng)器馬達(dá)類別：磁滯同步電機(jī)。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.
