Referring to fig. 1-3, the electromagnetic valve 200 operates according to the following principle:
In the use process of the electromagnetic valve 200, the piston 120 can be limited by connecting the end cover 130 with the valve core fixing seat 110, so that the movable stroke of the piston 120 is limited in the inner cavity 111 of the valve core fixing seat 110, and then the battery valve can form an independent movement mechanism in the use process, so that the structure of a shell and the like for limiting the movement of the piston 120 is simplified, and the electromagnetic valve 200 can be connected with an external valve seat 310 through the valve core fixing seat 110, so that the electromagnetic valve 200 is convenient to connect with an external structure, and the electromagnetic valve 200 can be applied to an independent electromagnetic valve 200 on a pipeline system and an inserted electromagnetic valve 200 for a thermal management integrated module, thereby improving the universality of the electromagnetic valve 200 and further reducing the use cost of the electromagnetic valve 200;
Specifically, when the electromagnetic valve 200 is used, the electromagnetic valve 200 is connected with an external valve seat 310 through the valve core fixing seat 110, and the magnetizer 211 is connected with the valve core fixing seat 110 or with the external valve seat 310, so that the electromagnetic valve can play a role in positioning and mounting, and when the electromagnetic coil 212 in the coil assembly 210 is electrified, the core 140 in the valve core assembly 100 can be driven to generate corresponding magnetic force, so that the piston 120 can be driven to move, and the conducting state of the valve seat 310 can be adjusted through the movement of the piston 120 after the electromagnetic valve 200 is connected with the external valve seat 310;
further, referring to fig. 1-3, in the present embodiment, when the core 140 is disposed, the core 140 includes a stationary core 141, a sleeve 142, a movable core 143, and a valve needle 144; the static iron core 141 is connected with the valve core fixing seat 110; the sleeve 142 is connected with the static iron core 141 and is used for forming a movable cavity 145 for the movable iron core 143 to move; one end of the valve needle 144 is connected with the movable iron core 143 positioned in the movable cavity 145, and the other end of the valve needle 144 passes through the static iron core 141 to be abutted with the piston 120;
The movable iron core 143 is used for moving relative to the movable cavity 145 under electromagnetic action, and driving the valve needle 144 to move towards the direction of the piston 120 so as to be abutted with the piston 120 and drive the piston 120 to move towards the direction of the end cover 130.
Thus, when solenoid 212 in coil assembly 210 is energized, plunger 143 in core 140 moves relative to movable chamber 145 under magnetic force, thereby driving piston 120 through valve needle 144 to move within chamber 111, such that piston 120 extends out of chamber 111 toward end cap 130 under the driving of valve needle 144, thereby moving relative to the flow path in outer valve seat 310 to adjust the opening and closing of the flow path in valve seat 310.
In order to control the movement stroke of the piston 120 during the movement of the piston 120, the valve core fixing seat 110 is matched with the end cover 130, so that the movement stroke of the piston 120 is limited, specifically, when the piston 120 moves, under the driving action of the valve needle 144, part of the piston 120 can extend out of the end cover 130 to be abutted with the external valve seat 310, and after the driving action of the valve needle 144 disappears, in order to enable the piston 120 to return to the original position, the valve core assembly 100 further comprises a piston spring 150 accommodated in the inner cavity 111, the piston spring 150 is sleeved on the piston 120, and two ends of the piston spring 150 are respectively abutted with the piston 120 and the end cover 130, wherein the piston spring 150 is used for enabling the piston 120 to have a trend of moving towards the direction of the core 140.

Referring to fig. 1-3, when the piston 120 is disposed, the piston 120 includes a first segment 121 and a second segment 122, wherein the outer diameter of the first segment 121 is smaller than the outer diameter of the second segment 122 along the axial direction of the piston 120, the outer diameter of the first segment 121 is smaller than or equal to the inner diameter of the through hole 131, and the outer diameter of the second segment 122 is larger than the inner diameter of the through hole 131; the piston spring 150 is sleeved with the first section 121 and abuts against the end portion, close to the first section 121, of the second section 122. By this arrangement, the first section 121 of the piston 120 can be extended from the end cap 130, while the second section 122 can abut the end cap 130 to limit the movement travel of the piston 120 and facilitate the installation of the piston spring 150. In addition, since the piston 120 is used to abut against the structure in the valve seat 310 when the piston 120 abuts against the flow path in the valve seat 310, the valve port gasket 123 is attached to the end of the piston 120 facing the end cap 130, that is, the valve port gasket 123 is provided to the end of the first segment 121 facing away from the second segment 122, in order to improve the sealing performance at the time of shut-off.
