(三线两控)进口电动二通阀 技术参数 Technical paramete

风机盘管电动二通阀（三线两控）不工作时处于常闭状态，当需要工作时，由房间温控器提供一个开启信号，使电动阀接通电源而动作，开启阀门，冷冻水或热水进入风机盘管，为房间提供冷量或热量；当室温达到房间温控器设定值时，房间温控器令电动阀断电，复位弹簧动作使阀门关闭，从而截断进入风机盘管的水流。通过阀门关闭和开启，使室温始终保持在房间温控器设定的温度范围内 RETZ electric two-way valve (three-wire two-way control) of fan coil is normally closed when it is not working. When it needs to work, the room temperature controller provides an opening signal to make the electric valve act by connecting the power supply, and open the valve. Chilled water or hot water enters the fan coil to provide cooling or heat for the room; When the room temperature reaches the set value of the room temperature controller, the room temperature controller will cut off the electric valve, and the return spring will act to close the valve, thus cutting off the water flow into the fan coil. By closing and opening the valve, the room temperature is always kept within the temperature range set by the room temperature controller.

风机盘管电动二通阀（三线两控）安装说明 Installation instructions

阀门安装角度要求如图1所示，当阀门装在垂直管道上时，马达外罩必须防止滴水渗入 The installation angle of the valve is as shown in Figure 1. When the valve is installed on the vertical pipe, the motor cover must prevent water from penetrating

阀门安装流向时由端“B”到端“A”，见图2  The flow direction of valve installation is from end "B" to end "a", as shown in Fig. 2

当安装常闭型驱动器时，必须先把手动操作杆扳到"开"处  When installing the normally closed driver, the manual operating lever must be turned to the "on" position first

当第一次使用时，手动操作杆会转移至自动位置上  When used for the first time, the manual operating lever will be transferred to the automatic position

电动阀时为全封闭式系统设计，不建议在开放式系统使用。在开放式系统里，过多的氧气及氯气溶解会侵蚀阀体材料，造成过早的损坏  The electric valve is designed as a fully closed system and is not recommended to be used in an open system. In an open system, excessive oxygen and chlorine dissolution will corrode the valve body material and cause premature damage
