Abstract
The utility model relates to an electronic expansion valve for a variable frequency air conditioner. The utility model is characterized in that a rotor rotating in a stator is provided with inner screw threads and outer screw threads; the inner screw threads are respectively provided with a rotor shaft rod, a spring, and a valve needle which can aim at a valve hole of a valve seat; the shaft rod is provided with a limiting mechanism; the lower end of the rotor is provided with a clamping mouth of a lower limiting mechanism; the upper end of the valve seat is provided with the clamping mouth. The utility model has the structure that the softness connection is arranged between the rotor shaft rod and the valve needle, so that the valve needle can move in the allowed range. Thus, the valve needle can not be locked in the valve hole.
Description
Technical field: the utility model relates to air conditioner electronic expansion valve technology field, belongs to electric micro computer specifically and controls automatically, by step motor drive, regulates the aperture between needle and the valve opening, regulates a kind of electric expansion valve of refrigerant flow.
Background technique: electric expansion valve in the market, its structure is made up of p-m rotor, stator and needle and valve opening.Send instruction by micro computer: given driving voltage makes the stepper motor rotation on kind of phase staor winding, when the burst direction was identical, pulse signal control step motor just changeed, on the contrary counter-rotating, thereby regulate the aperture between needle and the valve opening, regulate the flow of refrigeration agent.But a lot of electric expansion valve rotor shaft upper end is unsettled, there is not the fixed position, when rotor rotation, can produce and swing, destroyed the stability of system, general in addition position-limit mechanism all concentrates on position, upper end of axostylus axostyle, and complex structure, and spacing inaccurate, make the needle locking easily in valve opening.
Summary of the invention: the purpose of this utility model provides a kind of aperture of controlling rapidly and accurately between needle and the valve opening that has, and the rotor needle that can not swing simultaneously can the transducer air conditioning electric expansion valve of locking in valve opening yet.
For finishing the technological scheme that above-mentioned purpose is taked: the utility model comprises stator, rotor, needle and valve opening, establish in this stator and mould rotor, establish internal thread and outside thread with respect to the plastic magnetic rotor that rotates in the stator, internal thread is provided with rotor shaft, spring and needle respectively, needle is aimed at the valve opening of valve seat, an above-mentioned rotor shaft mechanism that limits, limit mechanism bayonet socket is set in above-mentioned plastic magnetic rotor lower end, and the end on the above-mentioned valve seat is established bayonet socket.
Adopt above-mentioned structure to establish reversible interface respectively in valve seat two sides, adopt above-mentioned structure simultaneously, axostylus axostyle upper end in the plastic magnetic rotor is provided with the fixed plastics part, and between needle and internal thread, establish retaining ring, and on the wall of internal thread chamber, establish exhaust port, between plastic magnetic rotor and stator shielding can is set in addition, sliding bearing is established in the axostylus axostyle upper end.
Staor winding is received the instruction that micro computer sends in sum, stepper motor rotates, the flow that causes in-migration regulating and controlling refrigeration agent on the needle, fixed plastics part fixed axostyle is set the while structure and axle end is connected with sliding bearing, upper and lower the moving of axostylus axostyle anti-system axostylus axostyle is swung, being provided with of retaining ring played leading role to needle, and establishing spring between more important rotor shaft and the needle is soft the connection, thereby needle can be not stuck in valve opening.
Description of drawings:
Fig. 1 is the utility model structural drawing.
Embodiment: according to shown in Figure 1, the plastic magnetic rotor 12 that rotates in the relative stator 10 is established internal thread 9 and outside thread 6, rotor shaft 14, spring 8 and needle 3 are set respectively in the internal thread, needle 3 is aimed at the valve opening 1 of valve seat 19, above-mentioned axostylus axostyle 14 mechanism 13 that limits, limit mechanism bayonet socket 16 is set in above-mentioned plastic magnetic rotor 12 lower ends, and bayonet socket 17 is established in above-mentioned valve seat 19 upper ends.Provided the position-limit mechanism of valve axostylus axostyle 14, rotor 12 according to above-mentioned structure.Valve seat 19 is established reversible interface 2 and reversible interface 20 respectively, and axostylus axostyle 14 upper ends in the plastic magnetic rotor 12 are provided with fixed plastics part 11, and anti-system axostylus axostyle 14 swings.Establish retaining ring 4 between needle 3 and the internal thread 9, needle 3 is played guiding function, while internal thread 9 chamber walls are provided with exhaust port 21 moves needle 3 flexibly.Between plastic magnetic rotor 12 and the stator 10 shielding can 15 is set, stator 10 and rotor 12 are isolated, sliding bearing 22 is established in axostylus axostyle 14 upper ends simultaneously, and the upper end that changes the prior art rotor shaft is unsettled.In addition owing to rotor adopts plastic magnetic rotor 12, overcomes the corrosion phenomenon of refrigeration agent to rotor 12.
