Abstract
The utility model relates to a kind of Novel efficient electronic expansion valve throttle system, outlet conduit place at electric expansion valve is provided with drainage cylindrical shell, drainage cylindrical shell be divided into be in turn connected with the outlet conduit of electric expansion valve along connect arc section, cross section and be 1/4 circular arc preparation expansion segment, be trumpet-shaped circular cone and expand cylinder section, it is the tube structure of both ends open and hollow that circular cone expands cylinder section, and circular cone expands a less open end of section and prepares expansion segment along connecing, be connected with pipe joint cylinder at a larger open end for circular cone expansion cylinder section by internal thread.The utility model is simple in structure, reasonable in design, the joint of unusual straight barrel type, and suitable arc section, preparation expansion segment, the circular cone expansion section of connecing of employing point three sections of designs, can carry out good drainage measure to the outlet liquid of electric expansion valve, with respect to traditional joint design, can significantly reduce the pressure loss, improve the flow efficiency of liquid simultaneously.
Description
Technical field
The utility model relates to a kind of Novel efficient electronic expansion valve throttle system.
Background technology
In known technical field, electric expansion valve is to regulate evaporimeter liquid supply rate according to pre-set programs, regulates pattern, therefore be called electric expansion valve because belonging to electronic type.It has adapted to the electrical integrated demand for development of refrigeration machine, has the incomparable good characteristic of heating power expansion valve, for the intellectuality control of refrigeration system provides condition, is a kind of rising auto-control energy-saving element.Electric expansion valve is identical with the basic purposes of thermal expansion valve, varied in structure, but in performance, both but exist larger difference.In actual use, often need to be to the joint of drainage be set in the outlet of electric expansion valve, can connect smoothly corresponding pipe-line system, the structure of general direct employing middle connector, still exists the pressure loss large, affects the flow efficiency of liquid.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of Novel efficient electronic expansion valve throttle system is provided, can reduce system pressure loss, improve the flow efficiency of liquid.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel efficient electronic expansion valve throttle system, comprise electric expansion valve, outlet conduit place at described electric expansion valve is provided with drainage cylindrical shell, described drainage cylindrical shell is divided into the suitable arc section that connects being connected with the outlet conduit of electric expansion valve in turn, cross section is the preparation expansion segment of 1/4 circular arc, be trumpet-shaped circular cone and expand cylinder section, it is the tube structure of both ends open and hollow that described circular cone expands cylinder section, and described circular cone expands the less open end of cylinder section and prepares expansion segment along connecing, the larger open end that expands cylinder section at described circular cone is connected with pipe joint cylinder by internal thread, and the outlet conduit internal diameter of described electric expansion valve be pipe joint cylinder internal diameter 1/5～1/8, between described pipe joint cylinder and circular cone expansion cylinder section, be provided with welded seal layer.
Further, as the ratio of best structure numerical value, described in the utility model along the arc radius that connects arc section be preparation expansion segment arc radius 1/4～1/3.
Further, as a kind of concrete embodiment, the tapering that circular cone described in the utility model expands cylinder section is 5 °～8 °.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the joint of unusual straight barrel type, and suitable arc section, preparation expansion segment, the circular cone expansion section of connecing of employing point three sections of designs, can carry out good drainage measure to the outlet liquid of electric expansion valve, with respect to traditional joint design, can significantly reduce the pressure loss, improve the flow efficiency of liquid simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. electric expansion valve, 2. drainage cylindrical shell, 21. along connecing arc section, 22. preparation expansion segments, 23. circular cones expand cylinder section, 3. pipe joint cylinder, 4. welded seal layer.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model Novel efficient electronic expansion valve throttle system as shown in Figure 1, comprise electric expansion valve 1, outlet conduit place at electric expansion valve 1 is provided with drainage cylindrical shell 2, described drainage cylindrical shell 2 is divided into the suitable arc section 21 that connects being connected with the outlet conduit of electric expansion valve 1 in turn, cross section is the preparation expansion segment 22 of 1/4 circular arc, be trumpet-shaped circular cone and expand cylinder section 23, 1/4～1/3 of the arc radius that the described suitable arc radius that connects arc section 21 is preparation expansion segment 22, the tapering that described circular cone expands cylinder section 23 is 5 °～8 °, tapering can only be within the specific limits, otherwise easily produce air gap, it is the tube structure of both ends open and hollow that described circular cone expands cylinder section 23, and described circular cone expands the less open end of cylinder section 23 and prepares expansion segment 22 along connecing, the larger open end that expands cylinder section 23 at circular cone is connected with pipe joint cylinder 3 by internal thread, and the outlet conduit internal diameter of electric expansion valve 1 be pipe joint cylinder 3 internal diameter 1/5～1/8, between pipe joint cylinder 3 and circular cone expansion cylinder section 23, be provided with welded seal layer 4.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
