Abstract
The utility model discloses a throttling device used by matching of capillary tubes and thermostatic expansion valves, which comprises a main solenoid valve connected with a liquid reservoir, wherein the main solenoid valve is respectively connected with a branch solenoid valve and a plurality of thermostatic expansion valves, and the thermostatic expansion valves are connected in parallel; and the branch solenoid valve is connected with a plurality of capillary tubes in parallel, and each capillary tube is connected with one thermostatic expansion valve. The throttling device provided by the utility model has the advantages that the refrigerating capacity can be enhanced and the refrigeration speed is accelerated so as to refrigerate two refrigeration houses simultaneously, and the refrigeration effect is favorable, and thus the equipment cost and resources can be saved.
Description
Technical field
The utility model discloses the throttling arrangement that a kind of capillary and heating power expansion valve are used.
Background technology
The freezer that uses at present all disposes a cover refrigerant compression condensation unit, makes the temperature in the freezer reach frozen state through refrigerant compression condensation unit.But when this cover refrigerant compression condensation unit is supplied with two freezers simultaneously; Refrigeration is obviously not all right, the single heating power expansion valve throttling of main still employing tradition, and the heating power expansion valve load is too big; If adopt two cover refrigerant compression condensation units, cost is obviously too big again.
The utility model content
The purpose of the utility model is the throttling arrangement that provides a kind of capillary and heating power expansion valve to be used; The utility model can pass through refrigerant compression condensation unit, can not only increase refrigerating capacity, and refrigerating speed is fast; Can supply with two freezers simultaneously; And cold storage effect is good, so just can drop into by minimizing equipment, can save resource again.
In order to achieve the above object, the technical scheme of the utility model is:
The throttling arrangement that a kind of capillary and heating power expansion valve are used comprises the total magnetic valve that is connected with liquid reservoir, it is characterized in that: this total magnetic valve is connected with branch way solenoid valve and a plurality of heating power expansion valve respectively, and these a plurality of heating power expansion valve parallel connections are provided with; This minute, way solenoid valve also was connected in parallel to a plurality of capillaries, and each capillary is connected with an above-mentioned heating power expansion valve.
The beneficial effect of the utility model is: simultaneously cold-producing medium is played throttling action through heating power expansion valve and capillary, can not only increase refrigerating capacity like this, and refrigerating speed is fast, can supply with two freezers simultaneously, and cold storage effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment 1
Throttling arrangement as shown in Figure 1, that a kind of capillary and heating power expansion valve are used comprises the total magnetic valve 1 that is connected with liquid reservoir 6, and this total magnetic valve 1 is connected with branch way solenoid valve 2 and a plurality of heating power expansion valve 3 respectively, and these a plurality of heating power expansion valve 3 parallel connections are provided with; This minute, way solenoid valve 2 also was connected in parallel to a plurality of capillaries 4, and each capillary 4 is connected with an above-mentioned heating power expansion valve 3.
The operation principle of the utility model: by the total magnetic valve 1 of cold-producing medium warp of liquid reservoir outflow; A cold-producing medium part gets into each heating power expansion valve 3 throttlings; Another part cold-producing medium gets into each capillary 4 through dividing way solenoid valve 2; Through capillary 4 throttlings, converge back (after evaporimeter heat exchange vaporization) through the cold-producing medium after the throttling of two places and return compressor 5 again.
