7010系列開關(guān)式電動(dòng)二通閥/丹富斯電動(dòng)二通開關(guān)閥簡(jiǎn)介
DF7010系列開關(guān)式電動(dòng)二通閥由DF7010系列閥門驅(qū)動(dòng)器和DF7010系列銅閥組成。用于控制冷水或熱水空調(diào)系統(tǒng)管道的開啟或關(guān)閉,達(dá)到控制室溫之目的。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)需要工作時(shí),由溫控器提供一個(gè)開啟信號(hào),使電動(dòng)閥接通交流電源而動(dòng)作,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)
閉或開啟,使室溫始終保持在溫控器設(shè)定的溫度范圍內(nèi)。
DF7010系列電動(dòng)閥之驅(qū)動(dòng)器與閥體采用螺套聯(lián)接方式,可以在閥門安裝之后,再安裝驅(qū)動(dòng)器,現(xiàn)場(chǎng)裝配,接線靈活、方便。 7010系列開關(guān)式電動(dòng)二通閥/丹富斯電動(dòng)二通開關(guān)閥
驅(qū)動(dòng)器之平面設(shè)計(jì)可以貼近墻面安裝,占用空間小。產(chǎn)品可靠耐用,工作噪音低,并能在隱蔽式風(fēng)機(jī)盤管裝置內(nèi)常出現(xiàn)的高溫環(huán)境可靠工作。
The switch type electric two-way valve, DF7010 series product introduction
By DF7010 DF7010 series switch type electric two-way valve series of valve drive and DF7010 copper valve series. Pipe is used to control the cold water or hot water air conditioning system of open or closed, to achieve the purpose of the control room temperature. Drive by one-way hysteresis synchronous motor drive, the valve spring return. Valve does not work in a normally closed state, when the need to work, provided by a thermostat open signal to make electric valve connected to the ac power and action, open the valve, chilled water or hot water into the fan coil units, to provide room air conditioning or heating; When the room temperature to the thermostat setting, temperature controller for electric power valve, reset spring to close the valve, to cut into the flow of fan coil units. Through the valve
Closed or open, make the room temperature always stay in the thermostat setting temperature range.
DF7010 series of electric valve drive with the valve body adopts a screw connection method, can be after installation, the valve again drive installation, field assembly, wiring flexibly and conveniently.
Drive the plane design can be installed close to the wall, small footprint. Products are reliable and durable, low operating noise, and can often appear in the concealment type fan coil of the high temperature environment and reliable work.
