產(chǎn)品簡介/Porduct Introduction
ST2系列熱力膨脹閥通過制冷劑的過熱度對進(jìn)入蒸發(fā)器中的液體制冷劑的供給量進(jìn)行調(diào)節(jié)，這種閥適用于干式蒸發(fā)器中制冷劑的自動(dòng)調(diào)節(jié)供給。
具有外部壓力平衡和內(nèi)部壓力平衡兩種形式，有效的外部壓力平衡系統(tǒng)消除了由于蒸發(fā)器壓力損失帶來的影響。
可換的閥芯易于存儲(chǔ)，方便機(jī)組調(diào)節(jié)容量與系統(tǒng)匹配，更便于維修。
蒸發(fā)溫度范圍大，從-40℃～+10℃
Thermostatic expansion valve regulate the flow rate of refrigerant into evaporators according to its degree of superheat.
Both the iternal equalizer and external equalizer systems are furnished,especially, the external equalizer type efficiently eliminates the influence resulted from the loss od evaporator pressure.
The interchangeable orifice is easy to store and maintain,making the equipment to match with the system with ease.
Wide range of evaporator temperature: -40℃～+10℃
