The invention discloses a coil assembly structure of an electromagnetic valve. The coil assembly structure comprises a magnetizer A (1), an outer cover (2), a coil (3), a jacking rod (4), a movable iron core (5), a magnetizer B (6), a magnetism isolating ring (7), a spring (8) and a magnetism isolating spacer (9). The magnetism isolating spacer (9) is arranged in an effective air gap formed by the magnetizer A (1) and the movable iron core (5) and is made of a non-magnetic-conduction material. The magnetism isolating spacer (9) is made of a 304 stainless steel material, the outer diameter of the magnetism isolating spacer (9) is not larger than the diameter of the movable iron core (5), and the thickness of the magnetism isolating spacer (9) is determined according to the turn-off current value of the electromagnetic valve. According to a designed coil assembly of the electromagnetic valve, by designing the novel coil assembly structure, the dependence of the performance of the electromagnetic valve on the part machining quality is reduced, the part machining difficulty of the electromagnetic valve is reduced, and the performance stability of the electromagnetic valve is improved.
Description
1. Technical field [0001] The invention belongs to the solenoid valve technology, and particularly relates to a solenoid valve coil assembly structure. 2. Background technology [0002] The solenoid valve is an electro-hydraulic conversion element, which consists of a coil assembly and an oil inlet assembly. The coil assembly is an electrical component, and its function is to generate electromagnetic force when the coil in the coil assembly inputs current. The movable iron core in the coil assembly is subject to the combined action of the spring force and the electromagnetic force. As the input current in the coil increases, the electromagnetic force continues to increase. When the electromagnetic force is greater than the spring force acting on the movable iron core, the movable iron core moves. Thus, the spool is driven to move, the solenoid valve is turned on, and the coil current at this time is called the turn-on current; when the current in the coil continues to decre...
