Abstract
A secondary throttle H-shaped automobile air conditioner thermal expansion valve belongs to the technical field of throttling of a vapor compression type refrigerating system, and is particularly suitable for being used as a throttling element in an automobile air conditioning device refrigerating system. The valve comprises a valve body (1), a valve needle (2), a steel ball (3), a valve port throttling channel (6), valve port throttling front channels (4) and (5), a valve port throttling rear channel (7) and a connecting hole (9); (10) and the orifice (8), the channel section of the orifice (8) is smaller than the maximum section of the valve port throttling channel (6). The high-pressure liquid refrigerant is subjected to secondary throttling, and the cross section of the throttling hole channel is a fixed value, and the cross section of the valve port throttling channel is automatically adjusted, so that the universal fluctuation and oscillation of the thermostatic expansion valve can be effectively solved, and the energy efficiency ratio and the refrigerating capacity of the refrigerating system are improved.
Description
Technical field
The present invention relates to a kind of second H type automobile air conditioner heat expansion valve, belong to the throttling technology field of vapour compression refrigeration system, be specially adapted to automobile air controlling device refrigeration system as throttle element.
Background technique
The H type automobile air-conditioning heating power expansion valve that now is used for the throttling of automobile air controlling 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, be difficult to overcome ubiquitous fluctuation of heating power expansion valve and vibration, cause refrigeration system Energy Efficiency Ratio and refrigerating capacity to descend.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, simple in structure, can not produce fluctuation and vibration at work, can improve the second H type automobile air conditioner heat expansion valve of refrigeration system Energy Efficiency Ratio and refrigerating capacity.
Second H type automobile air conditioner heat expansion valve of the present invention, comprise passage and attachment hole etc. after valve body, needle, steel ball, valve port throttling passage, valve port throttling prepass and the valve port throttling, passage is provided with throttle orifice after it is characterized in that valve port throttling prepass 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 the passage after valve port throttling prepass or the valve port throttling.
Described throttle orifice also can embed passage after valve port throttling prepass or the valve port throttling.
Second H type automobile air conditioner heat expansion valve of the present invention can fundamentally overcome ubiquitous fluctuation of heating power expansion valve or vibration owing to be provided with throttle orifice on the passage after valve port throttling prepass or the valve port throttling in automobile air controlling device refrigeration system.

Embodiment
First embodiment of second H type automobile air conditioner heat expansion valve of the present invention is as shown in Figure 1:
The compressed machine 41 of gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, become high pressure liquid refrigerant through condenser 42 condensations, high pressure liquid refrigerant drying cistern 43 enters second H type automobile air conditioner heat expansion valve 44 from the attachment hole 9 of second H type automobile air conditioner 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 vaporizer 45 heat absorption evaporations through attachment hole 10 becomes low-pressure gaseous refrigerant, gets back to compressor 41 through second H type automobile air conditioner heat expansion valve 44 top air cavitys and finishes refrigeration cycle.
Because high pressure liquid refrigerant through second throttle, therefore can effectively solve ubiquitous fluctuation of heating power expansion valve and vibration, improves the Energy Efficiency Ratio and the refrigerating capacity of refrigeration system.
