Abstract
The invention relates to a novel electronic expansion valve. The novel electronic expansion valve comprises a main body and a valve base. A pulse motor is arranged on the main body, a gear is arranged on the pulse motor, the gear is connected with a transmitting part, the transmitting part is connected with a pin valve, the pin valve is matched with a corrugated tube arranged in the main body, and the main body is fixedly arranged on the valve base. The novel electronic expansion valve is simple in structure, convenient to use and manufacture, suitable for mass production, small in size, reliable in running and good in sealing performance, the production cost is reduced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of novel electronic expansion valve.
Background technique
Electric expansion valve regulates vaporizer liquid supply rate according to pre-set programs, because belonging to electronic type shaping modes, therefore being called electric expansion valve, it has adapted to the electrical integrated demand for development of refrigerator, has the good characteristic that heating power expansion valve is incomparable, for the intelligentized control method 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 making system work under the best circumstances, but existing complex structure, be not suitable for producing in enormous quantities, bulky, it is unreliable to run, the shortcomings such as manufacturability is poor, and cost is high, and simultaneously sealability is poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of novel electronic expansion valve of applicable production in enormous quantities.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel electronic expansion valve, there is main body and valve seat, described main body is provided with pulse motors, pulse motors is provided with gear, gear is connected with drive part, drive part is connected with needle-valve, and needle-valve coordinates with the bellows be arranged in main body, and main body is fixedly installed on valve seat.
Further, the outer surface of described pulse motors is coated with waterproof jacket, waterproof jacket ensures that motor has good mode performance.
Further, described bellows is welded in main body by weld part.
The invention has the beneficial effects as follows: structure of the present invention is simple, use and easily manufactured, be applicable to producing in enormous quantities, volume is little, reliable, has good sealability, and reduction cost of production, increases the service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. main bodys, 2. valve seat, 3. pulse motors, 4. gear, 5. drive part, 6. needle-valve, 7. bellows, 8. waterproof jacket, 9. weld part in figure.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of novel electronic expansion valve as shown in Figure 1, there is main body 1 and valve seat 2, main body 1 is provided with pulse motors 3, pulse motors 3 is 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 be arranged in main body 1, main body 1 is fixedly installed on valve seat 2, the outer surface of pulse motors 3 is coated with waterproof jacket 8, and bellows 7 is welded on the body 1 by weld part 9.
Concrete pulse motors 3 driven gear 4 rotates, 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, structure is simple simultaneously, use and easily manufactured, be applicable to production in enormous quantities, volume is little, reliable, there is good sealability, reduce cost of production, increase the service life.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
