動態(tài)平衡電動二通閥在制冷和供熱系統(tǒng)中，風(fēng)機盤管通常由電動二通閥控制。當(dāng)一些風(fēng)機盤管關(guān)閉時，其他運行的風(fēng)機盤管流量進(jìn)口動態(tài)平衡電動二通閥2.jpg將增加，引發(fā)室溫波動。STV系列是集動態(tài)流量平衡閥和電動二通閥于一體的產(chǎn)品，由電熱執(zhí)行器控制。在閥門開啟時，通過動態(tài)平衡閥的恒流作用維持流經(jīng)設(shè)備的流量不變而不受系統(tǒng)壓力波動的影響，使控制精度更高。在制冷或供熱系統(tǒng)中，當(dāng)室溫達(dá)到房間溫控器設(shè)定值時，房間的溫控器發(fā)送信號到電熱執(zhí)行器，令閥門關(guān)閉。當(dāng)室溫高于或低于設(shè)定溫度時，房間溫控器發(fā)送信號到電熱執(zhí)行器，令閥門開啟。通過閥門關(guān)閉和開啟，使室溫始終保持在房間溫控器設(shè)定的溫度范圍內(nèi)。內(nèi)置平衡閥芯會自動保持流量恒定 RETZ dynamic balance electric two-way valve In refrigeration and heating systems, fan coil units are usually controlled by electric two-way valves. When some fan coils are closed, the flow of other fan coils in operation will increase, causing room temperature fluctuations. STV series is a product integrating dynamic flow balance valve and electric two-way valve, which is controlled by electric actuator. When the valve is opened, the constant flow of the dynamic balance valve keeps the flow through the equipment unchanged without being affected by the system pressure fluctuation, so that the control accuracy is higher. In the refrigeration or heating system, when the room temperature reaches the set value of the room temperature controller, the room temperature controller sends a signal to the electric actuator to close the valve. When the room temperature is higher or lower than the set temperature, the room temperature controller sends a signal to the electric actuator to open the valve. By closing and opening the valve, the room temperature is always kept within the temperature range set by the room temperature controller. The built-in balance valve core will automatically keep the flow constant.
