Abstract
A kind of nut seat of electric expansion valve disclosed in the utility model, including thread segment and guide section, thread segment one end is fixedly connected with guide section, thread segment other end connect setting through hole, thread segment is provided with internal thread linkage section, thread segment is integrally formed with guide section, it is circumferentially arranged in guide section to have some grooves, limited block is placed with groove, limited block includes limiting section and fixed part, limiting section is inside guide section, and fixed part is arranged in groove, supports being provided with back-moving spring between fixed part and bottom portion of groove.Its is simple and reasonable, improves the stability of electric expansion valve, adds service life.
Description
Technical field
The utility model is related to field of flow control, more particularly to a kind of nut seat of electric expansion valve.
Background technology
At present, electric expansion valve is widely used in throttling expansion and the Flow-rate adjustment of fluid, by nut seat and screw mandrel it
Between cooperation adjust flow.Existing nut seat generally includes thread segment and guide section, thread segment and guide section, thread segment one
End is fixedly connected with guide section, and the thread segment other end is connected with through hole, and thread segment is provided with internal thread linkage section.But nut
Screw thread between seat and screw mandrel, which coordinates, has certain thread pitch, so as to cause screw mandrel 4 to deviate wherein in rotation process
Heart axis, i.e., can occur when rotation it is certain rock, it is long so as to reduce the stability that electric expansion valve is operationally waited
Rocking for time makes the collision of screw mandrel and nut seat also to reduce its service life.
Utility model content
In view of the shortcomings of the prior art and defect, the utility model provides a kind of nut seat of electric expansion valve, its structure
Advantages of simple, improves the stability of electric expansion valve, adds service life.
To achieve the above object, the utility model provides following technical scheme.
A kind of nut seat of electric expansion valve, including thread segment and guide section, thread segment one end are fixedly connected with guide section,
Thread segment other end connect setting through hole, thread segment is provided with internal thread linkage section, and thread segment is integrally formed with guide section, guide section
It is interior it is circumferentially arranged have limited block is placed with some grooves, groove, limited block includes limiting section and fixed part, and limiting section is located at
Inside guide section, fixed part is arranged in groove, supports being provided with back-moving spring between fixed part and bottom portion of groove.
Further, limiting section is set in semicircle shape.
Further, also it is symmetrically arranged with fixture block on limited block.
Compared with prior art, the beneficial effects of the utility model are：Between screw mandrel and nut seat screw thread coordinate when
Wait, the cooperation by limited block to screw mandrel shaft, it is therefore prevented that screw mandrel shakes when screw thread coordinates between nut seat.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model standoff features schematic diagram.
In Fig. 1,1 thread segment, 2 guide sections, 3 through holes, 4 internal thread linkage sections, 5 grooves, 6 limited blocks, 61 limiting sections, 62 are consolidated
Determine portion, 63 fixture blocks, 7 back-moving springs.
Embodiment
Further explaination is done to the utility model with reference to accompanying drawing.
A kind of nut seat of electric expansion valve as shown in Figure 1, including thread segment 1 and guide section 2, the one end of thread segment 1 with
Guide section 2 is fixedly connected, the other end connect setting through hole 3 of thread segment 1, thread segment 1 be provided with internal thread linkage section 4, thread segment 1 with
Guide section 2 is integrally formed, in guide section 2 it is circumferentially arranged have limited block 6 is placed with some grooves 5, groove 5, limited block 6 is wrapped
Include limiting section 61 and fixed part 62, limiting section 61 is inside guide section 2, and fixed part 62 is arranged in groove 5, fixed part 62 with
Supported between the bottom of groove 5 and be provided with back-moving spring 7.
When screw thread coordinates between screw mandrel and nut seat, the cooperation by limited block 6 to screw mandrel shaft, it is therefore prevented that silk
Bar shakes when screw thread coordinates between nut seat.
Limiting section 61 is set in semicircle shape, and the setting of semicircle shape reduces the contact area between limiting section 61 and screw mandrel,
Reduce the friction between limiting section 61 and screw mandrel, it is therefore prevented that cause the reduction of valve body performance itself due to addition limited block 6.
Fixture block 63 is also symmetrically arranged with limited block 6, in the moving process of limited block 6, certain limit is played to limited block 6
Position effect.
Embodiment described above is not limited to the utility model, for a person skilled in the art, in this reality
With equivalent is carried out to which part technical characteristic within new spirit and principle, guarantor of the present utility model should be included in
Within the scope of shield.
