For achieving the above object, the valve body of idle call electronics expansion valve of the present utility model and coil location linkage structure, include valve body and coil, valve body is provided with location piece, coil is provided with location card, and described location piece comprises valve body positioning part and limited part, wherein, the valve body positioning part is fixed on valve body lower end or side, offers porose on the limited part or groove; Location card is made of coil location section and joint, and wherein, coil location section is fixed on the coil, and the hole on joint and the limited part or groove clamping matching form on the joint and prevent the bending of advancing and retreat.
Preferred as technique scheme, described location piece center is the circular hole shape, circular hole cooperates with valve body, is fixed in valve body lower end.
Preferred as technique scheme, described location piece is the tablet of bending, cylndrical surface and valve body are fixed.
Preferred as technique scheme, the hole on the limited part of described location piece or groove are more than one.
Preferred as technique scheme forms flange in the position of at least one hole or groove on the described limited part.
During preferred as technique scheme, the bending on the joint of described location card insert hole or groove on the limited part along valve axis or tangent to periphery direction.
Preferred as technique scheme, the joint integral body of described location card is " U " shape, two vertically section have at least one to form bending.
Preferred as technique scheme, the bending on the joint of described location card is semicircle or V-arrangement bending.
Preferred as technique scheme, the positioning part endoporus of described location card be circle.
The beneficial effects of the utility model are: because valve body is provided with location piece, coil is provided with location card, hole or groove screens that location card inserts on the location piece by the bending part distortion connect, can guarantee valve body and coil axes to and/or radially do not produce loosening, thereby improve the stability of electric expansion valve operation.In addition, because location piece is positioned at valve body lower end or sidepiece, in the basically identical situation of coil and magnet rotor height, can be close to the valve body upper end and reduces the height of magnet rotor, and finally reduce the whole height of electric expansion valve.
