Technical field
The present invention relates to a kind of second throttle bidirectional heat expansion valve, belong to the throttling technology field of steam compression heat pump type refrigeration system, be specially adapted to the heat-pump type air-conditioning device refrigeration system as throttle element.
Background technique
The two-way heating power expansion valve that now is used for the throttling of heat-pump type air-conditioning device refrigeration system, only experience automatic temperature control valve mouth throttling passage cross section and carry out a throttling by bellows, before the throttling and the channel cross-section after the throttling all greater than the maximum cross-section of valve port throttling passage, when the valve port channel cross-section that different and bellows is experienced valve port throttling passage cross section under the temperature and requirement when cooling condition and the desired flow of heating condition does not match, cause system's cisco unity malfunction.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, simple in structure, in the refrigeration system of heat-pump type air-conditioning device, the desired different flow of cooling condition and heating condition can be satisfied, the second throttle bidirectional heat expansion valve of refrigeration system proper functioning can be guaranteed.
Second throttle bidirectional heat expansion valve of the present invention, comprise (preceding) passage and connecting tube etc. after (back) passage before valve body, needle, steel ball, valve port throttling passage, the valve port throttling, the valve port throttling, (preceding) passage is provided with throttle orifice after it is characterized in that before the valve port throttling (back) passage or valve port throttling, and the channel cross-section of throttle orifice is less than the maximum cross-section of valve port throttling passage.
Described throttle orifice can directly directly be processed to form by valve body on (preceding) passage after (back) passage or the valve port throttling before the valve port throttling.
Described throttle orifice also can embed before the valve port throttling (preceding) passage after (back) passage or the valve port throttling.
Described throttle orifice also can be arranged on the end in the connecting tube of two ends.
Second throttle bidirectional heat expansion valve of the present invention since before the valve port throttling after (back) passage or the valve port throttling (preceding) passage be provided with throttle orifice, in the heat-pump type air-conditioning device refrigeration system, can satisfy the cooling condition traffic demand different, because the effect of second throttle can fundamentally overcome ubiquitous fluctuation of heating power expansion valve or vibration with heating condition.

Embodiment
First embodiment of second throttle bidirectional heat expansion valve of the present invention is as shown in Figure 1:
Throttle orifice 8 directly is processed to form by valve body 1, and the channel cross-section of throttle orifice 8 is less than the maximum cross-section of valve port throttling passage 6.Its working procedure such as Fig. 5 and 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 second throttle bidirectional heat expansion valve 44 from the connecting tube 9 of second throttle bidirectional heat expansion valve 44, 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 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 second throttle bidirectional heat expansion valve 44 from the connecting tube 10 of second throttle bidirectional heat expansion valve 44, 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 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 system.
