VA-7010系列電動(dòng)二通閥VA-7010系列電動(dòng)二通閥是專供中央空調(diào)風(fēng)機(jī)盤(pán)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(kāi)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(mén)打開(kāi)或關(guān)閉,實(shí)現(xiàn)管道冷水或熱水的通或斷,再通過(guò)風(fēng)機(jī)盤(pán)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(mén)彈簧復(fù)位,閥門(mén)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(kāi)啟信號(hào),使單向磁滯同步電機(jī)接通交流電源而動(dòng)作,通過(guò)齒輪傳動(dòng)推動(dòng)活塞式結(jié)構(gòu)閥體開(kāi)啟閥門(mén),冷凍水或熱水進(jìn)入風(fēng)機(jī)盤(pán)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(mén)關(guān)閉,從而截?cái)噙M(jìn)入風(fēng)機(jī)盤(pán)管的水流,通過(guò)閥門(mén)關(guān)閉和開(kāi)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(kāi)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.
