Abstract
The invention provides a thermostatic expansion valve with a damping structure, belonging to the throttling technical field of vapor compression type refrigerating systems. The thermostatic expansion valve is suitable for one-way operation and two-way operation. In the invention, the damping structure formed by an expansion tube (3) and an insert muffler (4) is arranged at one end or both ends of an inlet and outlet adapter tube (2), and most noise generated in the throttling process can be eliminated through the damping structure to enable the noise transferred to an indoor heat exchanger through a metal connecting tube to be reduced to be very low, therefore, the invention can not influence the life and the rest of people.
Description
Technical field
The present invention relates to a kind of heating power expansion valve, belong to the throttling technology field in the vapour compression refrigeration system, be applicable to the heating power expansion valve of various one-way only operations and two-way operation with noise elimination structure.
Background technology
Existing heating power expansion valve, especially for the two-way heating power expansion valve in the domestic air conditioning, the noise that produces in the throttling process reaches indoor heat converter by metal connecting tube, influences people's life and rest in night.
Summary of the invention
The heating power expansion valve that the purpose of this invention is to provide a kind of simple in structure, band noise elimination structure that noise is little.
The heating power expansion valve of band noise elimination structure of the present invention comprises the expansion valve body, imports and exports tube connector, it is characterized in that the one or both ends of importing and exporting tube connector are provided with convergent divergent channel.
Respectively there is one section interpolation pipe at described convergent divergent channel two ends.
In the described convergent divergent channel porous inner tube is arranged.
The heating power expansion valve of band noise elimination structure of the present invention, owing to be provided with noise elimination structure in the one or both ends of importing and exporting tube connector, the noise that produces in the throttling process can most of be absorbed by noise elimination structure, thereby reaches the purpose that reduces noise.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are three embodiment of the heating power expansion valve of band noise elimination structure of the present invention.
Fig. 4 is the refrigerating system figure of pump type heat air regulator.
Shown in Fig. 1,2,3:
1-expansion valve body, 2-imports and exports tube connector, 3-convergent divergent channel, 4-interpolation pipe, 5-porous inner tube.
Shown in Figure 4:
The 41-compressor, 42-four-way electromagnetic reversing valve, 43-outdoor heat converter, the two-way heating power expansion valve of 44-band noise elimination structure, 45-indoor heat converter.
The specific embodiment
Refrigeration system by embodiment shown in Figure 2 and pump type heat air regulator shown in Figure 4:
When heating, the compressed machine 41 of low-pressure gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, enter indoor heat converter 45 through four-way electromagnetic reversing valve 42, carry out the heat exchange heat release with room air and be condensed into high normal pressure and temperature liquid refrigerant, room air is heated up, high normal pressure and temperature liquid refrigerant is through the two-way heating power expansion valve 44 of band noise elimination structure, the throttling step-down becomes the low-pressure low-temperature liquid refrigerant, inlet chamber outer heat-exchanger 43, carry out heat exchange heat absorption evaporation with outdoor air and become low-pressure gaseous refrigerant, get back to compressor 41 through four-way electromagnetic reversing valve 42 and finish and heat circulation.
The noise that produces in the two-way heating power expansion valve 44 throttling step-down processes of band noise elimination structure, take over 2 by expansion valve body 1, import and export, be passed to the noise elimination structure of forming by interpolation pipe 4 and convergent divergent channel 3, most of noise can be absorbed, therefore, it is very little to reach the noise of indoor heat converter 45 by the metal connecting tube road.
During refrigeration, the compressed machine 41 of low-pressure gaseous refrigerant is collapsed into the high pressure-temperature gaseous refrigerant, through four-way electromagnetic reversing valve 42 inlet chamber outer heat-exchangers 43, carry out the heat exchange heat release with outdoor air and be condensed into high normal pressure and temperature liquid refrigerant, two-way heating power expansion valve 44 throttling step-downs through the band noise elimination structure become the low-pressure low-temperature liquid refrigerant, enter indoor heat converter 45, carry out heat exchange heat absorption evaporation with room air and become low-pressure gaseous refrigerant, make the room air cooling, low-pressure gaseous refrigerant is got back to compressor 41 through four-way electromagnetic reversing valve 42 and is finished kind of refrigeration cycle.
Equally, the noise that produces in the two-way heating power expansion valve 44 throttling step-down processes of band noise elimination structure, take over 2 by expansion valve body 1, import and export, be passed to the noise elimination structure of forming by interpolation pipe 4 and convergent divergent channel 3, most of noise can be absorbed, therefore, the noise that reaches indoor heat converter 45 by the metal connecting tube road reduces to very little, can not influence people's life and rest.
Claims (3)
