The utility model provides a solenoid valve 100 is applied to refrigerating system. The refrigerating system can be a refrigerating system of an air conditioner, a refrigerator or other refrigerating and heating equipment. The solenoid valve 100 is capable of controlling the refrigerant medium flow in the refrigeration system.
In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the solenoid valve 100 includes a valve body 10, a stationary core 20, a movable core 30, and a spacer 40, wherein the valve body 10 is provided with an accommodating cavity; the static iron core 20 is arranged in the accommodating cavity, and one end of the static iron core 20, facing the movable iron core 30, is convexly provided with an extending part 21; the movable iron core 30 is reciprocally and movably arranged in the accommodating cavity along the axial direction of the valve body 10, and a concave part 31 is concavely arranged at one end of the movable iron core 30 facing the static iron core 20; the spacer 40 is disposed on the protruding portion 21, so that when the stationary core 20 and the movable core 30 are attracted, the spacer 40 is stopped against between the protruding portion 21 and the concave portion 31, so that a gap is formed between the protruding portion 21 and the concave portion 31.
In the present embodiment, the accommodating cavity of the valve body 10 is used for accommodating the stationary core 20, the movable core 30, the spacer 40, the refrigerant medium, and other components of the solenoid valve 100. The valve body 10 is provided with a valve port 11 communicating with the receiving chamber, and the solenoid valve 100 controls the flow rate of the refrigerant by controlling the area of the valve port 11. The stationary core 20 is fixed at the top of the accommodating cavity, the movable core 30 is disposed at one side of the stationary core 20 facing the valve port 11, and the solenoid valve 100 further includes a coil assembly, which is sleeved at the periphery of the valve body 10 to generate electromagnetic force to drive the movable core 30 to move along the axial direction of the valve body 10.
The electromagnetic valve 100 in this embodiment is normally closed, when the electromagnetic valve 100 is in a power-off state, the electromagnetic force generated by the coil assembly disappears, the movable iron core 30 moves (i.e., resets) in a direction away from the stationary iron core 20 under the driving of its own gravity and/or an external force (e.g., an elastic force of the elastic member 50), and at this time, the distance between the movable iron core 30 and the stationary iron core 20 is gradually increased toward the electromagnetic valve 100; in the energized state, the electromagnetic force generated by the coil assembly is an attractive force, and the movable iron core 30 moves toward the stationary iron core 20 under the action of the attractive force, and at this time, the distance between the movable iron core 30 and the stationary iron core 20 gradually decreases. When the recess 31 of the movable core 30 contacts the spacer 40 provided in the protruding portion 21 of the stationary core 20, the moving speed of the movable core 30 is slowed, and when the movable core 30 stops moving (i.e., when the movable core 30 is attracted to the stationary core 20), a gap is formed between the recess 31 of the movable core 30 and the protruding portion 21 of the stationary core 20.
It can be understood that, when the movable iron core 30 and the stationary iron core 20 move relatively to each other, the protruding portion 21 is gradually inserted into the recess 31, and in this embodiment, the area of the opposite end surface between the stationary iron core 20 and the movable iron core 30 is increased by the way that the protruding portion 21 is matched with the recess 31, so as to increase the magnetic flux area when the stationary iron core 20 and the movable iron core 30 are energized, so as to provide a larger electromagnetic force for the movement of the movable iron core 30, and further, the electromagnetic valve 100 can be started under a smaller voltage.
It can be understood that the movable iron core 30 and the stationary iron core 20 are both made of a metal material, and if the movable iron core 30 directly collides with the stationary iron core 20, the movable iron core 30 and the stationary iron core 20 are easily worn away from each other, which affects the service life of the solenoid valve 100.
The technical scheme of the utility model, when quiet iron core 20 and movable iron core 30 actuation, stop to between the portion of stretching into 21 of quiet iron core 20 and the concave part 31 of moving iron core 30 through separator 40 to the clearance has between the portion of stretching into 21 and the concave part 31, thereby avoid moving and collide between iron core 30 and the quiet iron core 20, and then prevent to move and wear and tear each other between iron core 30 and the quiet iron core 20, prolong solenoid valve 100's life.

In one embodiment, as shown in fig. 2, the angle between the outer surface of the spacer 40 and the axis of the valve body 10 (as shown by c in fig. 2) is α, the angle between the surface of the protruding portion 21 and the axis of the valve body 10 is β, and α is greater than β.
It will be understood that, in an axial section of the valve body 10 coinciding with the axis of the valve body 10, the angle α between the outer surface of the spacer 40 and the axis of the valve body 10, i.e. the inclination of the outer surface of the spacer 40, and the angle β between the surface of the protrusion 21 and the axis of the valve body 10, i.e. the inclination of the surface of the protrusion 21, are greater the angle. Therefore, α > β can ensure that the outer surface of the spacer 40 protrudes from the surface of the protruding portion 21, so as to ensure that the movable iron core 30 contacts the spacer 40 first when the movable iron core 30 and the stationary iron core 20 move relatively, thereby avoiding direct collision between the movable iron core 30 and the stationary iron core 20.
