Description
Technical field
The utility model relates to a kind of novel electronic expansion valve.
Background technique
Electric expansion valve is to regulate vaporizer liquid supply rate according to pre-set programs, regulate pattern because belonging to electronic type, therefore be called electric expansion valve, it has adapted to the electrical integrated demand for development of refrigerator, has the incomparable good characteristic of heating power expansion valve, for the intellectuality control of refrigeration system provides condition, be a kind of rising auto-control energy-saving element, electric expansion valve is identical with the basic purposes of thermo expansion valve, varied in structure, but in performance, but there is larger difference in both.
Along with the flow adjustment range to refrigeration system, speed, precision etc. require greatly to improve, for system is worked under the best circumstances, but existing complex structure, be not suitable for producing in enormous quantities, bulky, it is unreliable to move, the shortcomings such as manufacturability is poor, and cost is high, and while sealability is poor.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of novel electronic expansion valve of applicable production in enormous quantities is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel electronic expansion valve, there is main body and valve seat, in described main body, be provided with pulse motors, on pulse motors, be provided with gear, gear is connected with drive part, drive part is connected with needle-valve, and needle-valve coordinates with the bellows being arranged in main body, and main body is fixedly installed on valve seat.
Further, on the outer surface of described pulse motors, be coated waterproof jacket, waterproof jacket ensures that motor has good mode performance.
Further, described bellows is welded in main body by weld part.
The beneficial effects of the utility model are: the utility model is simple in structure, and use and easily manufactured is applicable to producing in enormous quantities, and volume is little, reliable, has good sealability, reduces production costs, and increases the service life.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. main bodys in figure, 2. valve seat, 3. pulse motors, 4. gear, 5. drive part, 6. needle-valve, 7. bellows, 8. waterproof jacket, 9. weld part.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of novel electronic expansion valve as shown in Figure 1, there is main body 1 and valve seat 2, in main body 1, be provided with pulse motors 3, on pulse motors 3, be provided with gear 4, gear 4 is connected with drive part 5, and drive part 5 is connected with needle-valve 6, needle-valve 6 coordinates with the bellows 7 being arranged in main body 1, main body 1 is fixedly installed on valve seat 2, is being coated waterproof jacket 8 on the outer surface of pulse motors 3, and bellows 7 is welded in main body 1 by weld part 9.
Concrete pulse motors 3 driven gears 4 rotate, gear 4 is connected with drive part 5, and drive part 5 drives needle-valve 6 to move up and down, and realizes switch and opens and closes motion, simultaneously simple in structure, use and easily manufactured, is applicable to producing in enormous quantities, and volume is little, reliable, there is good sealability, reduce production costs, increase the service life.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
