(二线)进口风机盘管电动二通阀 技术参数 Technical paramete

风机盘管电动二通阀（二线）由单向磁滞同步电机驱动，弹簧复位。阀门不工作时处于常闭状态，当需要工作时，由温控器提供一个开阀信号，使电动阀接通交流电源而动作，开启阀门，冷冻水或热水进入风机盘管，为房间提供冷气或暖气；当室温达到温控器设定值时，温控器令电动阀断电，复位弹簧使阀门关闭，从而截断进入风机盘管的水流。通过阀门关闭或开启，使室温始终保持在温控器设定的温度范围内  RETZ electric two-way valve (two-wire) of fan coil unit is driven by one-way hysteresis synchronous motor with spring return. When the valve is not working, it is normally closed. When it needs to work, the temperature controller provides a valve opening signal to make the electric valve act by connecting the AC power supply, open the valve, and the chilled water or hot water enters the fan coil to provide air conditioning or heating for the room; When the room temperature reaches the set value of the temperature controller, the temperature controller will cut off the electric valve, and the return spring will close the valve, thus cutting off the water flow into the fan coil. Keep the room temperature within the temperature range set by the thermostat by closing or opening the valve

风机盘管电动二通阀（二线）安装说明 Installation instructions

常闭二通阀和分流三通阀的安装如图一、图二及图三所示。对干高层建筑物，应在底层支管上采用减压阀 RETZ installation of normally closed two-way valve and shunt three-way valve is shown in Fig. 1, Fig. 2 and Fig. 3. For dry high-rise buildings, pressure reducing valves shall be used on the bottom branch pipes

（图一）二通阀  (figure I) two way valve

当安装常闭二通阀时，水流方向是由“B”端至“A”端，对常开阀门流动是由“A”端至“B”端  When the normally closed two-way valve is installed, the water flow direction is from "B" end to "a" end, and for the normally open valve, the flow direction is from "a" end to "B" end

（图二）三通阀  (Figure 2) three way valve

（图三）三通阀  (Fig. 3) three way valve

三通阀当安装分流三通阀时,“B”端为供应端,“A”端为旁通端，入口是没有标记的，“A”和“B”孔标记于阀体底部  When the three-way valve is installed, the "B" end is the supply end, the "a" end is the bypass end, the inlet is not marked, and the "a" and "B" holes are marked at the bottom of the valve body

注意 be careful

马达罩应防止滴水渗入。当阀装入水平管道，安装位置与垂直平面夹角不应超过85℃（见图四）。当阀门在垂直管道上时，马达罩壳必须防止滴水渗入  The motor cover shall prevent water dripping. When the valve is installed in the horizontal pipeline, the angle between the installation position and the vertical plane shall not exceed 85 ℃ (see Fig. 4). When the valve is on the vertical pipe, the motor housing must prevent dripping

手支操作杆当把手动杆沿箭头指向慢慢移动并按进缺口内卡住，阀门处于常开状态。每当电流首次通过电动阀时，手动杆再设定至自动位置  When the manual lever is moved slowly along the direction of the arrow and pressed into the notch, the valve is normally open. Whenever the current passes through the electric valve for the first time, the manual lever is reset to the automatic position

如果驱动器没有预先安装在阀体上，需要安装时，先将驱动器的操作杆沿箭头方向推入凹槽中，按驱动器边上的黑色按钮，在阀体上放好后松开，即可装上。如需拆卸，重复上述操作  If the driver is not installed on the valve body in advance, when it needs to be installed, first push the operating rod of the driver into the groove in the direction of the arrow, press the black button on the side of the driver, place it on the valve body, release it, and then install it. If disassembly is required, repeat the above operation

注意 be careful

水流方向应同阀体上箭头指向一致安装时，驱动器不得作为受力的支点  The direction of water flow shall be consistent with the arrow on the valve body. During installation, the driver shall not be used as the fulcrum of stress
