丹富斯電動兩通調節閥

1、概述           電動二通閥、電動兩通閥、

我公司電動兩通調節閥閥體有鑄銅、鑄鐵、鑄鋼、不銹鋼多種材質可供選擇，以適合不同工作介質及溫度的要求，閥體有螺紋連接和法蘭連接兩種，安裝方便，其構造符合IEC標準，閥體結構形式有兩通閥（單座）、兩通平衡閥（平衡式）、三通合流和三通分流閥產品功能執行器選用鑄鋁支架及塑料外殼，體積小、重量輕      

2、特點 　　                   電動二通閥、電動兩通閥、

選用永磁同步電機，并帶有磁滯離合機構，具有可靠的自我保護功能，適合多種控制信號：增量（浮點）、電壓（0～10V）、電流（4～20mA），具有0～10V或4～20mA反饋信號（選配）

電動兩通調節閥系列能調節蒸汽或冷熱水的流量，廣泛用于*空調、采暖、水處理、工業加工行業等系統的流體控制。

3、工作原理                         

驅動器是由可逆同步馬達驅動，并帶磁性離合器。馬達通過馬達轉子與離合器所產生的磁性作用，能在停頓的情況下產生穩定的扭力。故此當馬達設有電流通過時能穩定地停頓在任何一點，當閥門全開或全關時磁離合器分離，停止調節。驅動器的遞增式或比例式控制器所發訊號能使馬達順時轉動或逆時轉動，傳動齒輪采用金屬齒輪，大大提高了驅動器的使用壽命，功耗低、輸出力大、噪音小，本系統適用于空調系統的新風機組冬/夏季溫度控制，由溫度傳感器TE-1，比例積分溫度控制器TC-1和電動兩通調節閥TV－1組成送風溫度控制系統，安裝在送風管道的TE－1把檢測到的溫度信號傳送至TC－1，由TC－1將TE－1的檢測值與設定值不斷比較，同時不斷地輸出信號，控制TV，TV-1的開度連續可調。zui終使TE－1測量的環境溫度保持在設定溫度范圍內。 　　

當盤管后的溫度低于某限值時，低溫保護開關TS-1切斷送電機的電源，從而使 新風風閥關閉，防止盤管內的水結冰，漲裂盤管。（具體不詳細之處，來咨詢）

Dan fuss electric two-way valve 
 
1, an overview of the 
 
Our company electric two-way regulating valve body has cast copper, cast iron, cast steel, stainless steel variety of material to choose from, in order to suit the requirements of different working medium and temperature, the body has two kinds of threaded connection and flange connection, easy installation, its structure accord with IEC international standard, the body structure has a two-way valve (single), two-way balancing valve (balanced), the 3-way confluence and tee diverter valve actuator product function selects the aluminum bracket and the plastic shell, small volume, light weight 
 
2, the characteristics of 
 
Use permanent magnet synchronous motor, and with hysteresis clutch mechanism, has reliable self-protection function, suitable for a variety of control signals: increment (float), voltage (0 ~ 10 v), current (4 ~ 20 ma), with 0 ~ 10 v or 4 ~ 20 ma feedback signal (optional) 
 
Electric two-way valve series can regulate the flow of steam or hot and cold water is widely used in central air conditioning, heating, water treatment, industrial processing industry, etc. The fluid flow control system. 
 
3, the working principle of 
 
Drive by reversible synchronous motor drive and magnetic clutch. Motor by the motor rotor and magnetic effect produced by the clutch, can generate stable torque in the case of a pause. Therefore when the motor is equipped with an electric current passes through can steadily pause at any point, when the valve is fully open or close the magnetic clutch, stop adjustment. Drive incremental or proportional controller sends signal can make the motor starts to rotate chronological or reverse rotation, use a metal gear transmission gear, greatly improving the service life of the drive, low power consumption, big output power, low noise, fresh air units of the system is suitable for use in air conditioning systems in winter/summer temperature control, the temperature sensor TE - 1, pid temperature controller and electric two-way regulator TV TC - 1-1 of supply air temperature control system, installed on the air supply pipeline of TE - 1 to the temperature of the detected signals to TC - 1, will TE by TC - 1-1 of values compared with the set value constantly, constantly output signal at the same time, control the TV, TV - 1 opening continuously adjustable. Eventually keep TE - 1 measurement of temperature in setting temperature range.  
 
When after the coil temperature is below a certain threshold, low temperature protection switch cut off TS - 1 to send the power of the motor, so that fresh air valve closed, prevent water ice coil, coil up to crack. (not in detail, to call)
