Abstract
The utility model relates to a combined throttle device of an electronic expansion valve, which comprises an electronic expansion valve (1), capillary tubes (2) and a solenoid valve (3). The electronic expansion valve (1) and the capillary tubes (2) are connected in parallel, and the solenoid valve (3) and the capillary tubes (2) are connected in series. By utilizing the structure the combined throttle device of the electronic expansion valve expands ranges of flow regulation and is more applicable to multi-frequency conversion units.
Description
Technical field:
The utility model relates to refrigeration and field of air conditioning, specifically is a kind of electric expansion valve combination throttling arrangement that is used for the connected unit.
Background technology:
In traditional refrigeration system, the overwhelming majority adopts capillary or heating power expansion valve to carry out throttling.In the last few years, along with convertible frequency air-conditioner is popularized, the research of various control theories, electric expansion valve has obtained extensive use.
Because connected unit load change, return liquid during for fear of little load during heating operation and excessive discharge temperature when loading greatly, off-premises station must use electric expansion valve to carry out flow-control, to adapt to the change of load.Along with the requirement of building energy-saving, large-scale connected unit had progressively obtained popularization in recent years.Off-premises station need use control accuracy higher, the electric expansion valve that flow is bigger.
A kind of combination throttle control device that utility model patent 200520134571.0 proposes, with electric expansion valve and capillary paralleling, though can improve the refrigerant circulation of throttling arrangement, but the upper and lower bound that is actually adjustable range improves simultaneously, the amplitude of the cold medium flux adjustable range that throttling arrangement is controlled does not but change, in addition because capillaceous must the use makes throttling arrangement be suitable for the connected machine set system from begin adjusting less than flow capillaceous.
The utility model content:
The technical problems to be solved in the utility model is, overcomes the defective of prior art, and a kind of flow adjustment range that enlarged is provided, and is applicable to the electric expansion valve combination throttling arrangement of connected unit more.
Technical solution of the present utility model is, a kind of electric expansion valve combination throttling arrangement is provided, and it comprises electric expansion valve and capillary, described electric expansion valve and capillary paralleling, and it also comprises magnetic valve, described magnetic valve is connected with capillary.
After adopting said structure, the utlity model has following advantage:
Whether the utility model can be controlled capillary by cut-offfing of magnetic valve in parallel with electric expansion valve, thereby increased the upper limit of the refrigerant circulation adjustable range of electric expansion valve combination throttling arrangement, widen flow adjustment range, be applicable to the electric expansion valve combination throttling arrangement of connected unit more.
Description of drawings:
Accompanying drawing is the schematic diagram of the utility model electric expansion valve combination throttling arrangement.
As shown in the figure: 1, electric expansion valve, 2, capillary, 3, magnetic valve.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of electric expansion valve combination throttling arrangement, and it comprises electric expansion valve 1 and capillary 2, and described electric expansion valve 1 is in parallel with capillary 2, and it also comprises magnetic valve 3, and described magnetic valve 3 is connected with capillary 2.
With specific embodiment operation principle of the present utility model is described below, for example, the flow adjustment range of electric expansion valve 1 is 55～450, the flow of capillary 3 is 200, then when magnetic valve 2 disconnects, capillary 3 does not use, then the adjustable range of electric expansion valve combination throttling arrangement is still 55～450, when magnetic valve 2 is opened, capillary 3 is in parallel with electric expansion valve 1, then the adjustable range of electric expansion valve combination throttling arrangement is 255～650, and so then can the adjustable range of whole electric expansion valve combination throttling arrangement be widened by cut-offfing of magnetic valve 2 be 55～650.
Certainly; above-mentioned explanation is not to be limit value to essential scope of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art person has done in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
