va-7010系列電動(dòng)二通閥是中央空調(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(hào),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。

motorized two-way valve
va-7010 series motorized two-way valve , consisting of valve bodyand actuator driven by hysteresis motor, are speciallycoupled with fan coil of commercial air conditioners tocontrol the medium( hot or cold water) in the coil through a roomthermostat. as a result, it can achieve automatic temperaturecontrol.
when power on, actuator started by synchronous hysteresis motoropen valve,and when power off, spring return close valve. valve isclosed off when it is not in use. when the room temperature isabove or below the set-point, thermostat send a power signal toactuator that will connect to power, open valve ,input hot water orchilled water to fan coil unit. by doing this, the cooling orheating air will be provided to the room. when the room temperaturereached the set-point, thermostat cut off power, motorized valvecloses, spring switch returns , the hot water or chilled water isblocked in fan coil unit. by valve opening and closing, the roomtemperature can be maintained at the set-point.
