Description
Technical field
It the utility model is related to detent mechanism built in a kind of plug-in type of electric expansion valve.
Background technology
The installation positioning of electric expansion valve is typically to be realized by being attached to the elastic locating mechanism outside valve body, such as：
ZLZL2012202506137 and ZL2012202404345 is two electric expansion valve, and installation detent mechanism is attached to valve by the former
The lower section of body, and detent mechanism is then attached to the top of valve body by the latter, can be with although schemes that both are set are different
Find out flexibly positioned its volume of the structure type being arranged on outside valve body is all bigger.
The content of the invention
The utility model be a kind of plug-in type of electric expansion valve built in detent mechanism, can be substantially reduced using this technology
The volume of electric expansion valve, while structure can also be simplified, reduce production cost.
In order to solve the above problems, the utility model is achieved through the following technical solutions, it by rotor, stator outside
Shell, flexibly positioned head, insert sealing composition.Rotor its structure employed in described rotor and ZL2012202404345 is basic
Identical (omit herein to internal rotor construction be described), appearance is cylindrical, and upper end is round platform top, lower end and feed tube and
Drain pipe connects, near the round platform top on a circumference of periphery, the uniform 4 pieces positioning pits for elastic positioning head positioning.
Described stator casing is plastic products, and profile approximation is in round platform scalariform, and the section of centre one is big cylinder, and laying installation thereon connects
The boss of line card, shield, both ends set small cylinder.The inside of stator casing is shoulder hole, and big cylinder hollow part installs stator
Coil, small cylinder aperture excessively coordinate with rotor, and upper small cylinder outer surface sets a convex tendon intersected with big cylindrical end face,
End face sets flat-top, and flat-top center sets a small ventilating holes, and the rectangular opening that sealing is inserted in installation is set at flat-top convex tendon, is carried on the back in hole along convex tendon
Face sets the groove for installing flexibly positioned head and slotting sealing.Described slotting sealing is made from a plastic material, and is inserted sealing and is corresponded to stator
The plane projection of outer casing groove is T-shaped, and side projection is in inverted L-shaped, and long side is the cutting to match with stator casing groove size,
Short side is then matched for be biased in long side one with stator casing flat-top rectangle hole shape and the sealing handle with edge sealing.Institute
The flexibly positioned head stated is formed by sheet metal punching, is assigned to the elasticity that positioning head meets location requirement, and flexibly positioned head is overall
Width can move freely in stator casing groove.During assembling, first the embedded stator coil in stator casing, installs wiring
Card, flexibly positioned head and slotting sealing are sequentially loaded into groove, and rotor is inserted stator by the slotting sealing that then press...withes one's finger, slightly
Rotation allows flexibly positioned head to fall into the positioning pit of rotor.Method when changing installation position is also very simple, as long as rotating
The relative position of son and stator casing, it is overlapping with the positioning pit in required orientation to be threaded to flexibly positioned head.

Embodiment
Rotor (4) appearance is cylindrical, and upper end is round platform top, and lower end is connected with feed tube (6) and drain pipe (7), in circle
Near platform top on a circumference of periphery, the uniform 4 pieces positioning pits for elastic positioning head (2) positioning.Outside described stator
Shell (3) is plastic products, and profile approximation is in round platform scalariform, centre one section be big cylinder, thereon laying installation wiring card (8),
The boss of shield (9), both ends set small cylinder.The inside of stator casing (3) is shoulder hole, and big cylinder hollow part installs stator
Coil (5), small cylinder aperture excessively coordinate with rotor (4), and upper small cylinder outer surface sets one and intersected with big cylindrical end face
Convex tendon, end face sets flat-top, and flat-top center sets a small ventilating holes, sets the rectangular opening that sealing (1) is inserted in installation at flat-top convex tendon, in hole
The groove for installing flexibly positioned head (2) and slotting sealing (1) is set along the convex tendon back side.Described slotting sealing (1) is by plastic material system
Make, insert sealing (1) correspond to stator casing (3) groove plane projection it is T-shaped, side projection is in inverted L-shaped, and long side is and stator
The cutting that shell (3) groove size matches, short side are then one and stator casing (3) flat-top rectangular opening being biased in long side
Shape matches and the sealing handle with edge sealing.Described flexibly positioned head (2) is formed by sheet metal punching, is assigned to positioning head
Meet the elasticity of location requirement, flexibly positioned head (2) overall width can move freely in stator casing (3) groove.During assembling,
