Embodiment
First embodiment of the second throttle bidirectional heat expansion valve of the utility model band filtration is as shown in Figure 1:
If the heat-pump type air-conditioning device refrigeration system is in cooling condition, then the compressed machine 41 of gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, become high pressure liquid refrigerant through 43 condensations of four-way electromagnetic reversing valve 42 inlet chamber outer heat-exchangers, high pressure liquid refrigerant enters the second throttle bidirectional heat expansion valve 44 of band filtration from the left liquid connecting tube 9 of the second throttle bidirectional heat expansion valve 44 of band filtration, through valve port throttling prepass 4,5 enter and experience temperature by bellows and regulate the valve port throttling passage 6 of channel cross-section automatically and carry out the throttling first time, high pressure liquid refrigerant becomes the low-pressure low-temperature gas-liquid mixed refrigerant after the throttling first time, passage 7 enters throttle orifice 8 and carries out the throttling second time after the valve port throttling, the low-pressure low-temperature gas-liquid mixed refrigerant becomes pressure and temperature after the throttling second time lower, the gas-liquid mixed refrigerant that the gaseous refrigerant ratio is higher, entering indoor heat converter 45 heat absorption evaporations through right liquid connecting tube 10 becomes low-pressure gaseous refrigerant, gets back to the circulation that compressor 41 is finished cooling condition through four-way electromagnetic reversing valve 42.
If heat-pump type air-conditioning device is in heating condition, then the compressed machine 41 of gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, enter indoor heat converter 45 condensations through four-way electromagnetic reversing valve 42 and become high pressure liquid refrigerant, high pressure liquid refrigerant enters the second throttle bidirectional heat expansion valve 44 of band filtration from the right liquid connecting tube 10 of the second throttle bidirectional heat expansion valve 44 of band filtration, carry out the throttling first time through throttle orifice 8, enter valve port throttling passage 6 through valve port throttling prepass 7 and carry out the throttling second time, passage 4 after the gas-liquid mixed refrigerant behind the second throttle passes through the valve port throttling, 5 and left liquid connecting tube 9 inlet chamber outer heat-exchangers 43 heat absorption evaporation become low-pressure gaseous refrigerant, get back to compressor 41 through four-way electromagnetic reversing valve 42 and finish and heat circulation.
Because during cooling condition, the valve port throttling passage 6 that can regulate channel cross-section automatically is first throttle, throttle orifice 8 is second throttling, and during heating condition, throttle orifice 8 is throttling for the first time, the valve port throttling passage 6 that can regulate channel cross-section automatically is throttling for the second time, in heat-pump type air-conditioning device, during forward and reverse work, can satisfy the desired different flow of cooling condition and heating condition, second throttle can fundamentally overcome ubiquitous fluctuation of heating power expansion valve and vibration simultaneously, improves the Energy Efficiency Ratio of refrigeration system.Owing to be equipped with filter screen 2 between valve body 1 and left liquid connecting tube 9 and the right liquid connecting tube 10, during no matter forward and reverse work, all the remaining impurity in the refrigeration system can be blocked in outside the thermal expansion innervalve assembly assurance refrigeration system proper functioning.
