三通電動(dòng)調(diào)節(jié)閥

三通電動(dòng)調(diào)節(jié)閥three-way electric control valve

1.     依工作溫度（℃）及適用流體來決定閥的型號(hào)。

In accordance with the working temperature (℃) and the suitable fluid to determine valve model.

2.     依流量值（KVS）來決定閥的口徑。

In accordance with the flow value (KVS) to determine the valve diameter.

3.     依壓力值（△P）來決定傳動(dòng)器的形式。

According to the pressure value (△P) to determine the type of driver.

型號(hào)（type）：Baodi-240/242-B-AD-P21-3/6/12/18-Fu/Fo

形式（form）：242=三通（three-way），240=三通（three-way）（分流，混合式Shunt, mixed type）

操作壓力（operating pressure）：3=1.2kg/cm², 6=1.2kg/cm², 12=1.2kg/cm², 18=1.2kg/cm²

操作方式（mode of operation）：Fu=通氣開（Ventilation opening），F(xiàn)o=通氣關(guān)（Ventilation, close）

工作溫度（working temperature）：-20℃~+350℃

本體耐壓（body pressure）：PN16及PN25（PN16 and PN25）（壓差值參考表the reference table difference pressure）

傳動(dòng)器耐溫（motor temperature）：-10℃~+80℃

口徑（Caliber）：DN15~DN150mm（1/2”~6”）

流量值（flow value）：參考表（reference table）

適用流體（application of fluid）：蒸汽，熱水，水，氣體，油品（steam, hot water, water, gas，oil）

本體材料（the material of the body）：碳鋼/球墨鑄鐵（carbon steel/ductile cast iron）

Fu和Fo在外形上識(shí)別（Fu and Fo in shape recognition）：

Fu（如下左圖）：壓縮空氣入口在上端，通氣時(shí)閥門打開，即圖中A與AB暢通，在平常不通氣時(shí)，A與AB之通路是關(guān)閉的，故稱常關(guān)（OPG）.

Fu（below, the picture on the left）：Compressed air entrance at the upper end, ventilation valve open, namely A and AB map is smooth, usually is not ventilation, A signaling pathway with AB is closed, so that the normally closed (OPG)

Fo（如下右圖）：壓縮空氣入口在下端，通氣時(shí)閥門關(guān)閉，即圖中A與AB不通，在平常不通氣時(shí)，A與AB之通路是暢通的，故稱常開（OPO）.

Fo（below, the picture on the right）：Compressed air entrance at the lower end, close the valve when the ventilation, namely A and AB barrier in the picture, in the usual no ventilation, A and AB channel is unimpeded, so normally open (OPO).

混合式控制及配管方式（Hybrid control and Piping manner）：

1.     控制閥在安裝時(shí)，不論是混合式控制或是分流式控制，其安裝位置請盡量靠近耗能設(shè)備（如圖中之V）,以增進(jìn)控制效果。

Control valve is installed, either hybrid control or flow control, its installation position please as close as possible to the energy consuming equipment (as shown in figure V), in order to enhance the control effect.

2.     控制閥在工作時(shí)，由于閥門可以停止在任何位置，因此：a閥桿往傳動(dòng)器方向移動(dòng)時(shí)（上升）表示閥門漸關(guān)，則主流A→AB通量就逐漸減少，副流B→AB 通量就逐漸增加。b閥桿往B方向移動(dòng)時(shí)（下降）表示閥門漸開，則主流A→AB 流量逐漸增加，副流B→AB 通量逐漸減少。

Control valve in the work, because the valve can stop at any position, so the valve stem to the driver: a direction (up) the valve that is the mainstream gradually, A →AB flux will reduce gradually, side stream B →AB flux increasing gradually. B stem to B direction (down) that the valve gradually opened, the main stream A →AB rate increases gradually, side stream B →AB flux decreases gradually.
