1) double parallel expansion valve
双路并联膨胀阀
2) double expansion valve
双膨胀阀
3) dou-ble ported thermostatic expansion valve
双向膨胀阀
4) two-valved configuration
并联双阀
1.
Two parallel-placed needle valves with opposite flow direction referred as two-valved configuration instead of traditional single-valved configuration as double-inlet are adopted to control DC flow and are proved to be a successful way to decrease the refrigeration temperature of a single-stage pulse tube cryocooler below 20 K.
并联双阀双向进气模式是采用了两个并联排列、箭头指示方向相反的阀门来替代单一阀门的双向进气模式,可对脉管制冷中的直流进行有效控制,是使脉管制冷机单级情况下达到低于20 K温区的有效手段。
5) double valve parallel connection
双阀并联
6) 2-way TEV
双向热力膨胀阀
1.
Compares the test result that is tested under the same conditions & normal charged amount of original system with original system equipped with 2-way TEV,combined the price factors of each throttling element,and points out that the application of 2-way TEV in heat pump water heater is feasible and its performance and price ratio is high.
