Embodiment Construction
[0037] The following describes the implementation in detail in conjunction with the accompanying drawings.
[0038] The electric valve of the present invention realizes the reliable positioning of the coil by improving the structure and connection relationship between the coil fixing frame and the positioning card; at the same time, the matching relationship between the welding parts is combined with the optimally designed weld position to improve the electric valve. High pressure capability.
[0039] see Figure 4 , which is a schematic diagram of the overall structure of the present invention.
[0040] The main structure of the solenoid valve of the present invention is the same as that of the prior art. As shown in this figure, it includes a magnetic rotor (not shown) and a valve needle (not shown) placed in the housing 41, a stator 40, a valve seat 43, a positioning card 45 and a coil holder 44; wherein, the stator 40 is a yoke made of a coil box 42, a soft magnetic mate...
