FLUID PRESSURE (TEMPERATURE) CONTROL, 3-STAGE DECOMPRESSION JET-TRIM(CIRCULAR) EXPANSION VALVE |
摘要 |
The present invention relates to an expansion valve of a turbo cooler. The present invention is designed to control expansion of a coolant and a flow rate of the coolant in accordance with a temperature setting value using a mechanism of an electrical motor driven controller (31). The jet-trim expansion valve used for the turbo cooler maximizes refrigerating performance (RT) by mounting a flow control device of a one-stage jet-trim (51) to a front end of the inside of a valve main body of a ball valve using the flange type ball valve and is decompressed in two stages by a two-stage jet-trim (71) mounted in a ball opening portion (42) inside a ball (40) in the ball valve in order to improve the refrigerating performance (RT) to improve the minimum power (kW/RT) of a compressor of the cooler to maximally save energy. |
