332 are placed in third stage portion 335.Third section 333 is equipped with flange part 336 and extension 337, and flange part 336 can be with valve body
11 step surface the 4th stage portion 15 directed downwardly abuts limitation valve rod 33 and moves axially upward, and extension 337 is in flat ligule, energy
Enough it is embedded in the groove 121 of spherical spool 12.So set, being limited to the axial position of valve rod 33, send out it axially not
Raw larger displacement is circumferentially able to drive spherical spool 12 and rotates.
It is envisioned that valve rod 33 can also be designed to separate structure, i.e. second segment 332 and third section 333 is used as one
It is a to be made into integration entirely through metal bar material Vehicle Processing formation or powder metallurgy, from the end of 332 side of second segment to valve rod
Circular groove is opened in 33, first segment 341 is that cylindrical bar is processed to be formed, and first segment 341 is inserted into above-mentioned circular groove to connect the two.
Further, as shown in Figure 1, driving part 2 further includes bracket 24, which includes the first of receiving motor 21
Second receiving portion 242 of the first magnetic rotatable parts 22 of receiving portion 241 and receiving, the first receiving portion 241 and the second receiving portion 242 it
Between be equipped with partition board portion 243, the partition board portion 243 offer can power supply machine 21 the through-hole that passes through of output shaft 211, partition board portion 243 is logical
The end thereof contacts with output shaft 211 with motor 21 are crossed, partition board portion 243 can support motor 21.First magnetic rotatable parts 22
It is equipped with axial gap between partition board portion 243, axial gap is equipped between the first magnetic rotatable parts 22 and the top of shell 41.Tool
Body, the height of the second receiving portion 242 is greater than the thickness of the first noumenon 221 of the first magnetic rotatable parts 22；The output of motor 21
Axis 211 and the first connector 224 of the first magnetic rotatable parts 22 are fixed by rivet or weld.When it is implemented, due to motor
21 output shaft 211 has certain axial gap, and the first magnetic rotatable parts 22 and the second magnetic rotatable parts 32 are axially adjacent to setting
When setting, the mutual attractive force formed between the two can elongate output shaft 211, and the second receiving portion 242 is placed in shell ontology 45
On top, as long as therefore guaranteeing that the height of the second receiving portion 242 is greater than the thickness of the first noumenon 221 of the first magnetic rotatable parts 22
Degree, the first magnetic rotatable parts 22 can be made neither to contact with partition board portion 243, also do not contacted with the top of shell ontology 45, make its
Frictional force is not generated in rotary course, reduces the loss for the power that rotates in a circumferential direction.The outer peripheral surface of second receiving portion 242 is also provided with radial direction
Crossed beam trunking, can power supply machine 21 lead 212 it is protruding.
Wiring board can also be arranged in driving part 2, and wiring board is set to bracket 24, when wiring board is used to adjust the operating of motor
Between, angle is circumferentially rotated within the scope of 90 ° so as to control spherical spool 12, the uninterrupted of refrigerant is adjusted.Motor
21 lead 212 first passes through wiring board, then protruding by the crossed beam trunking that the outer peripheral surface of the second receiving portion 242 opens up.
The motor-driven valve of present embodiment drives the rotation of the first magnetic rotatable parts to produce in driving method using low-power machine
Raw rotating excitation field, makes the second magnetic rotatable parts that the first magnetic rotatable parts be followed to rotate synchronously, and will be turned round using gear reduction
Square amplification, so that circumferentially rotating with ovable valve stem makes the spool bore of spherical spool be connected to or disconnect refrigerant channel.Present embodiment
Motor-driven valve is by being fixedly connected to form confined space for shell and valve part in structure, and external with motor-driven valve is isolated, valve
Bar is set to the confined space, and valve rod one end is protruded into valve part and spherical spool is driven to circumferentially rotate, and realizes refrigerant channel
Forward and reverse opening and closing.Using this structure, have the advantages that flowing to for refrigerant is unrestricted, it is forward and reverse to be all opened and closed；It is cold
From when circulating forward or backwards, play will not all occur matchmaker for spherical spool, be conducive to the generation for inhibiting noise；Spherical spool is circumferential
Rotation is the process of gradual change, and refrigerant flows into low-pressure side from high-pressure side, will not generate enormous impact to spherical spool, be conducive to inhibit
The generation of noise；Deceleration mechanism, valve rod, spherical spool are all set in confined space, are conducive to inhibit refrigerant leakage, are improved valve
Reliability；Motor power itself is smaller, has energy-saving effect；Spherical spool flow resistance is smaller, and only in the switching of opening and closing
Energy consumption is generated in journey, energy-saving effect is good.
A kind of motor-driven valve provided by the present invention is described in detail above.Specific case used herein is to this
The principle and embodiment of invention is expounded, method of the invention that the above embodiments are only used to help understand and
Its core concept.It should be pointed out that for those skilled in the art, in the premise for not departing from the principle of the invention
Under, it can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection of the claims in the present invention
In range.
